SHORT STORY
Five years after the original Lexus RX300 created the luxury sport utility segment and
became a best seller with more than 500,000 units sold worldwide, the new generation
Lexus RX300 further raises the segment benchmarks. The new RX300 improves on every
aspect of the outgoing model, making a quantum leap in safety, driving dynamics and
refinement to move it even further ahead of other vehicles in the luxury SUV segment.
In redefining the RX300 for its next generation of buyers, the Lexus development team
concentrated on creating a vehicle that could deliver excellent dynamic performance –
especially in handling and ride comfort – NVH and braking. It was determined from the
outset that the new RX300 should have advanced styling, unsurpassed levels of active and
passive safety and a host of innovative features.
The power of the 3.0-litre transversely-mounted high-performance V6 engine is increased to
201bhp by improving the intake and exhaust systems. The powerplant, which already
complies with the 2005 Euro IV emission standards, is complemented by a new five-speed
automatic transmission with a sequential gearchange and a new drivetrain in which the
torque distribution between the front and rear wheels is controlled electronically by the
Traction Control (TRC) system. A more aerodynamic body and higher-performance tyres
increase the top speed from 112 to 124mph, while improving combined fuel consumption by
more than six per cent, achieving a best in class figure for luxury SUVs equipped with sixcylinder petrol engines.

In addition to offering class-leading aerodynamic efficiency with a Cd figure as low as 0.33
(SE-L equipped with air suspension) and a wind noise level 5dB lower than its predecessor,
the new Lexus RX300 is distinguished by bold new looks. The RX300 shares styling cues
with other Lexus models, with the distinctive grille design, modern, clear glass lamps front
and rear, strong wheel arches, a rising window line and a distinctive ‘c-post’ rear pillar
design.
The modern and distinctive shape also gives a passenger compartment that is bigger and
roomier than most of its segment rivals. At 4,740mm in length, the new Lexus RX300 is
160mm longer than its predecessor and 30mm wider, with refined packaging giving an extra
100mm of wheelbase for additional luggage load space. Despite the greater length, the
turning radius remains a compact 5.7m.
A further comfort and convenience feature offered by the new generation RX300 is a poweroperated rear-tailgate, standard on the SE and SE-L, automatically opening and closing at
the touch of a button. It can also be activated remotely by the vehicle’s key. To ensure safe
operation, the system features a warning buzzer. By receiving information from the touch
sensors and the electric motor, the system ECU can stop the door and reverse its movement
when there is any obstruction to its closing action.
Rear end styling and safety are equally enhanced by lamps which use the latest LED (light
emitting diode) technology rather than traditional filament bulbs. These are more energy
efficient and a significant active safety item. The LED elements light up 10 times faster than
a conventional lamp, 2 to 15 milliseconds as opposed to 150 to 200msec. This equates to
six metres of reaction time at 62mph.
The new Lexus RX300 takes the lead in all areas of active and passive safety. Uppermost
are the excellent driving dynamics, aided still further by Vehicle Stability Control (VSC),
Traction Control (TRC) and Brake Assist (BA) technology. Additionally, the new RX300
carries more safety equipment than any other vehicle in its segment.
A new Air Suspension System, fitted to the RX300 SE-L, offers a still higher level of
performance and refinement. This feature provides greater ride control together with an
auto-levelling function and the ability to alter ride height through a range of 45mm.
Intelligent AFS (Adaptive Front-lighting System), a world-first for SUVs, radically improves
night-driving visibility when cornering. Unlike other systems which either use additional
lamps or are merely directly linked to a car’s steering, the Intelligent AFS microprocessor
controller calculates the optimum swivel of the lighting area from the vehicle speed and
3
steering angle. It is combined with xenon headlights with an automatic levelling system and
headlamp cleaners for the best night-time vision.
A further aid to active safety is the use of a Lexus Parking Assist Monitor. Effectively a TV
camera mounted in the rear, it is a unique feature among luxury SUVs. When reverse gear is
selected, an image appears on the navigation display screen on the dashboard, allowing
accurate manoeuvring and minimising the risk of collision with low-level objects.
To further advance the model’s leadership in passive safety performance the new RX300
features as standard equipment dual stage driver and front passenger SRS airbags and a
first-in-segment driver’s SRS knee airbag. New Extra-large Side Airbags (protecting torso,
abdomen and pelvis) and standard side curtain shield airbags offer supplemental protection
for occupants in side impacts.
Yukihiro Okane, Lexus RX300 Chief Engineer, said: “The new RX300 is intended to give its
users a feeling of freedom. It is comfortable and pleasurable to drive, both on your everyday
commute or on weekend leisure activities away from town.
“The original RX300 created a new segment in the world of SUVs by establishing an
indisputable combination of a fully-grown luxury car with a competent SUV. For the new
generation we had to concentrate on maintaining our leadership position in the segment we
have created. This is the reason why the new RX300 has evolved in every possible way to
become a more assertive vehicle.”
Commenting on the new Lexus RX300, Stuart McCullough, Director Lexus Europe, said:
“We are still selling the outgoing RX300 very successfully but with the new model we have
the opportunity to fundamentally alter the dynamic of the dealer network. We have the
advertising tagline for the launch ‘The New RX300 – It Changes Everything’. Whilst that’s
intended to be a statement about the impact that the car will have on its segment, actually
it’s equally relevant to our dealer network. The volume and the profit opportunity that exist
within the car will enable our dealers to invest further to create the kind of network that we
need.
“The new RX300 will continue to be our second-highest volume selling car, a very, very
close second to the IS. It will play a big role in helping to establish the business generally. It
is a car which will bring people to Lexus who may not have considered a saloon car. It has a
role in ensuring the balance and breadth of our customer base.”

DEFINITION AND EQUIPMENT: A NEW GENERATION OF THE WORLD’S MOST
SUCCESSFUL LUXURY SUV
Fourteen years ago, Lexus arrived among the world’s established luxury car makers as a
totally new brand, with dramatic new products and the philosophy of ‘The Relentless Pursuit
of Perfection’.
The aim behind Lexus was to create the world’s finest luxury automobile brand. That
translated into offering customers exclusivity, intelligent design, integrity, attention to detail
and the highest standards of customer service. The marque was first launched in the USA in
1989, with the debut of LS400 ‘premium luxury sedan’. From the moment it entered the
market, LS400 was hailed as one of the finest cars ever made.
THE CREATION OF RX300
Lexus quickly carved a niche for itself and, in 1993, became the number one luxury import
brand in the USA. By the mid-1990s, Lexus had earned a reputation for setting new
standards of customer satisfaction. Now was the time for Lexus to branch out, presenting
new, but still distinctively Lexus products. First came a luxury sports saloon, the Lexus GS.
Then in 1998 Lexus launched the RX300 on the American market, its first distinct sport utility
vehicle (SUV).
The successful core philosophy behind the RX300 was to offer the commanding ride height
and off-road functionality of an SUV without sacrificing the comfortable ride, handling and
convenience of a luxury car. A sophisticated and efficient 3.0-litre VVT-i V6 engine was
combined with a four-wheel drive powertrain and suspension designed for exceptional onroad driving dynamics. Innovations, such as the first Active Control Engine Mount, ensured
the highest levels of refinement, as expected of a Lexus.
“The breakthrough was building a 4x4 with a monocoque body and car-like driving dynamics.
Up until that point everybody had been building truck-like SUVs on ladder-frames,” says
Lexus Europe Director, Stuart McCullough. “It gave RX300 the ability to have the ride height
and capability of a 4x4 with the refinement and the driving dynamics of a car which behaved
like an upmarket saloon. A number of our rivals obviously agree – they’ve tried to follow us
ever since!”
From the moment of its unveiling at the 1998 North American International Automobile Show
in Detroit, RX300 proved a runaway success; establishing an all-new segment in the market
on both sides of the Atlantic and beating both established domestic and imported brands in
5
the USA. This also created increased awareness of the Lexus brand among a wider
audience, driving sales of the full range of models. Lexus became the number one-selling
luxury brand in the United States, outperforming Mercedes-Benz, BMW, Audi, Lincoln,
Cadillac and all other luxury competitors.
The total number of RX300 models sold in the United States stood at 355,942 by the end of
2002, making up 68 per cent of the worldwide total of 525,021. In Europe, more than 15,000
RX300 models have been sold since the model was launched in early 2000.
NEW RX300: SALES AND POSITIONING
The new-generation Lexus RX is set to move the class standard still higher. The new model,
known as the RX330 in the USA, received rave reviews following its unveiling at the North
American International Auto Show in January 2003 and similar excitement is growing in
Europe, after its static launch at the Geneva Motor Show. The aim is to sell around 7,000 of
the new RX300 in Europe in the first year. The IS sports saloon and SportCross will remain
the top selling Lexus model at around 10,000 units.
In the UK sales of the current generation RX300 have reached 4,166 since launch in 2000.
In 2003 Lexus (GB) aims to sell 2,300 units, rising to 3,900 in 2004, the first full year of
sales.

BODY: STYLED FOR A ‘DYNAMIC AND HIGH PERFORMANCE IMAGE’
The new Lexus RX300 is distinguished from its predecessor by bold new looks, which
combine the most advanced elements of SUV styling with a sporting and dynamic image,
together with a distinctive C-post rear pillar design. Lexus design cues can be easily
identified in areas such as the headlights and front grille.
DESIGN: RENOUNCING CONVENTIONALITY
Some typical elements were incorporated in the RX300’s exterior design in order to mark a
very clear Lexus identity. The familiar vertically latticed grille is combined with further Lexus
styling cues, including modern, clear glass lamps front and rear, strong wheel arches and a
rising window line. Large 17-inch six-spoke or 18-inch five-spoke alloy wheels give the car
an imposing image and the complete side profile makes the new RX300 instantly
recognisable.
The inspiration for the RX300’s distinctive shape stems from the project’s chief designer,
Takumi Ichikawa, who has a passion for aeroplanes. The dynamism of their shapes was an
8
inspiration for the exterior design of the RX. A further aircraft-inspired element is the rising
belt line to the rear – expressing the speed and stance of a jet fighter aircraft.
The tailgate design features an integral rear spoiler which aids aerodynamic efficiency and
stability and helps keep the rear window clean. The rear lamp clusters combine clear lenses
and the latest LED (light emitting diode) technology.
AERODYNAMICS: WORLD’S BEST LUXURY SUV
In addition to the manufacturer's own wind tunnel, the new generation RX300 has also been
developed at the Maibara wind tunnel. Maibara was also used for the development of the
Shinkansen Bullet Train, as well as other Lexus models, including the LS430. Here the
RX300 was tested in wind speeds of up to 125mph.
The Maibara wind tunnel was also used because of its very low background noise. This
allowed Lexus to concentrate on the reduction of wind noise. Further flow analysis was
undertaken by Computational Fluid Dynamics, with areas such as the positioning of the
parked windscreen wipers and the shaping of the A-pillars being refined to reduce wind
noise by an average of 5dB at all frequencies.
In addition to achieving superior airflow characteristics over the visible body surfaces, careful
tuning of underbonnet and underbody aerodynamics contributes to a class leading Cd figure
of 0.34. Fairings ahead of each wheel smooth out the airflow around the front and rear tyres,
while an aerodynamic engine undercover, floor undercovers, a specially shaped fuel tank,
rear undercovers and a spare tyre cover are all designed to produce a smooth airflow.

This Cd figure is cut to 0.33 on models equipped with air suspension. This system
automatically reduces ride height at speed by 7.5mm, further optimising the vehicle’s
aerodynamic performance. This makes the RX300 the world’s most aerodynamic SUV.
PACKAGE
A combination of intelligent packaging within a modern and distinctive shape gives the new
RX300 compact exterior dimensions but a passenger compartment that is bigger and has
more useable space than most of its segment rivals. The new Lexus RX300 is 160mm
longer than its predecessor and 30mm wider. A wheelbase longer by 100mm increases
luggage capacity. Even accounting for the longer wheelbase, the turning radius remains a
compact 5.7m.
While the RX300 is optimised for on-road performance, short front and rear overhangs
provide excellent approach and departure angles for off-road driving. This is further
enhanced on models equipped with air suspension, which can increase the car’s ground
clearance from the standard 185mm to 205mm.

BUILD QUALITY: ACHIEVING BEST IN CLASS NVH
The construction of the new Lexus RX300 body further enhances the car’s dynamic
capabilities, efficiency and durability. The body structure is manufactured from high strength
sheet steel ensuring the highest levels of body rigidity and a light weight. The use of
additional fastening and reinforcement in the front suspension tower, front cowl panel and
around the entire back door opening all contribute to the vehicle’s rigidity and NVH
performance. There is also strategic use of sound absorbing and vibration damping
materials.
The build quality of the new RX300 plays a major role in both NVH and perceived quality.
Accurate ‘cutline management’ yields a big improvement in fit between lamp units and body
panels.
SAFETY: A CLEAR LEADER IN THE SUV SEGMENT
One of Lexus’s highest priorities for the new RX300 is an unparalleled level of occupant
safety. Not only is the new RX300 a class leader in its own right, it is expected to influence
the safety provisions in all SUVs to come, setting new standards by combining a vast range
of innovative technologies into an integrated approach embracing structural, active and
passive safety.
Uppermost are the excellent driving dynamics, further aided by Vehicle Stability Control
(VSC), Traction Control (TRC) and Brake Assist (BA) technology. Additionally, the new
RX300 carries more active and passive safety equipment than any other vehicle in its
segment.
PASSIVE SAFETY
Standard equipment includes multi-stage driver and front passenger SRS airbags. These
work in conjunction with impact absorbing structures in the front end of the vehicle and the
pretensioner-equipped seat belts to reduce shocks to the head, chest and legs in the event
of a frontal collision.
The multi-stage driver and passenger airbag system is linked to a seat position sensor,
crash severity sensor and the seatbelt buckle switch (which detects whether or not the belt is
fastened). Using information from these sources, it judges the best inflation level for each
airbag according to the immediate circumstances. These ‘intelligent’ airbags, by neither
under nor over-inflating, greatly enhance the security of driver and passengers.
11
The provision of a driver’s SRS knee airbag in the RX300 – a first for the segment – is likely
to reduce significantly injuries to the legs, which are common in major frontal impacts. The
knee airbag deploys from the lower part of the instrument panel at the same time as the front
airbag. It is primarily designed to reduce injury from contact with steering column and lower
dashboard structures, but has also been found to reduce head and chest injuries by
reducing displacement of the pelvis and rotation of the torso in a major impact.
Further protection is provided by an energy absorbing mechanism in the steering column.
When a major impact is transmitted to the steering mechanism in a collision, a breakaway
bracket separates, causing the entire column to move forward, away from the driver. Energyabsorbing plates and brackets also reduce impact forces delivered to the steering wheel.
To complement this feature, the RX300 is also equipped with a collapsible pedal system. In
the event of a frontal collision, pedals will disengage and move forward from their original
position to minimise potential injuries to the driver’s feet.
In the event of a side-impact, the impact-absorbing structure of the RX300 is reinforced by
side curtain shield airbags that provide passengers with extra head protection. These inflate
from the top of the door frames to help reduce the impact energy transmitted to the driver,
front passenger and outer rear seat passengers in the event of a side collision, effectively
creating a pneumatic ‘curtain’ over the window area.
This side protection is further enhanced by the world’s first use of extra-large SRS ThoraxAbdomen-Pelvis (TAP) Side Airbags. These airbags have a capacity of 16 litres, at least six
litres more than conventional side airbags. This means they can reduce the risk of chest and
abdomen injuries by spreading the forces over a wider area, covering torso, abdomen and
pelvis. In spite of their size, the TAP Airbags are mounted in the seats rather than on doors,
so they remain in the ideal position however far back or forward the seat is positioned. In
total, the new Lexus RX300 is equipped with nine airbags.
Seats in the new RX300 have been designed to WIL (Whiplash Injury Lessening) principles.
The design incorporates innovations in headrests and seat backs that decrease neck motion
in a rear end collision. By reducing the motion between head and torso, the seats have been
shown to significantly lessen the incidence of whiplash injury.
To provide optimum safety, the airbags work in conjunction with three-point electronically
sensing pretensioned seatbelts, fitted to both the front and rear seats. The rear seat is
12
designed with built-in Seat Belt Comfort Guides to ensure the correct positioning of the
seatbelts for children or smaller passengers. An ISOFIX bar for securing child seats has
been provided behind the rear seat cushion. In addition, three CRS anchor brackets for
securing child seats are provided on the rear seat backrests.
The ‘intelligent’ electronic seat belt pretensioners and force limiters allow full freedom of
movement under normal circumstances, but instantly restrain the body in an impact.
Triggered by the ignition signal from the airbag sensor, the seatbelt pretensioner activates
simultaneously with the front airbags. At the start of the collision, if the tension of the seatbelt
reaches a predetermined level, the force limiter is activated to reduce the force exerted on
the occupant.
The overall structural strength of the new RX300 also plays a significant part in protecting its
occupants. Reinforcements have been added to the inner and outer rocker panels, front
pillars, and roof side rails in order to minimise cabin deformation during a frontal collision.
Impact energy from a side collision directed to the cabin area is dispersed throughout the
body via the central pillar, reinforcements, side impact protection beams and floor cross
members.
ACTIVE SAFETY
The impact absorbing structure and passive safety equipment in the new RX300 are really
designed as a final resort. Of perhaps greater importance is the maximisation of Active
Safety, the use of design, technology and driving dynamics to avoid potential accident
situations in the first place.
Electronic traction control (TRC), a multi-channel anti-lock braking system (ABS), with
Electronic Brake-force Distribution (EBD), Brake Assist (BA) and a Vehicle Stability Control
(VSC) system all add to the vehicle’s dynamic handling characteristics.
13
The purpose of the innovative VSC system is to aid stability during cornering. The system
monitors the vehicle's behaviour during cornering and maintains stability by using the car’s
ABS and TRC sensors to apply small amounts of asymmetric braking to correct oversteer or
understeer before it occurs. The primary roles of the TRC and ABS are to provide stability
under acceleration or braking.
Further significant safety enhancements are the use of EBD, which uses the anti-lock
braking sensors to equalise front and rear brake force distribution and Brake Assist, which
interprets a quick push of the brake pedal as emergency braking and supplements the
braking power applied to maximise performance in conjunction with ABS.
The elevated driving position of the RX300 is itself an important active safety feature. At
night or in bad weather the Intelligent AFS, Adaptive Front-lighting System, radically
improves visibility when cornering by directing the front headlight low beam towards the
inside of a curve. Intelligent AFS is equipped with an electronic controller which calculates
the optimum degree of light swivel from information received on vehicle speed and steering
angle.

Unlike rival systems which are merely directly linked to a car’s steering, or use additional
lights, the Intelligent AFS controls the lighting direction of each headlamp light
14
independently. It is also combined with High Intensity Discharge (HID) headlights with an
automatic levelling system and headlamp cleaners.
An automatic rain sensing windscreen wiper system on the SE and SE-L versions and a
spray windscreen wash system on all models ensure the best possible visibility in poor
weather. This is further aided by the use of water-repellent glass, which is specially coated to
maintain clear vision through the front side windows.
A further aid to active safety is the use of the Lexus Parking Assist Monitor, effectively a TV
camera mounted at the rear and a unique feature among luxury SUVs. When reverse gear is
selected, an image appears on the navigation display screen on the dashboard. This helps
accurate manoeuvring and reduces the risk of collision with low-level objects.
Providing a final touch of style, technology and safety at the rear of the new RX300 are
combination lamp units which use the latest LED (light emitting diode) technology rather than
traditional filament bulbs. In the case of the brake lights, their more rapid response time is a
significant active safety item. The LED elements light up 10 times faster than a conventional
lamp, between 2 and 15 milliseconds as opposed to 150 to 200msec. This equates to an
extra six metres of ‘reaction time’ at 62mph.
INTERIOR: ORIGINAL, ATTRACTIVE, WITH A NEW APPROACH TO
CONVENIENCE
As well as the customary standards of Lexus comfort, ambience, practicality and luxury, the
new RX300 combines the latest contemporary design with the highest quality materials and
an even higher level of perceived quality. The interior design features ample
accommodation, with plenty of storage places; a ‘segment-first’ Power Tailgate; and rear
seats that are multi-adjustable, including a ‘flat-floor’ folding system.
DESIGN AND PERCEIVED QUALITY
Design inspiration for the interior came from not just the automotive industry, but from a
wider range of craftsmanship and hand-made luxury goods. High quality musical instruments
are a typical example of how different materials can be seamlessly worked to combine both
practicality and aesthetic beauty. Lexus designers have spent time with musical instrument
craftsmen to learn more of their special timber moulding techniques used in making pianos,
violins and guitars.
15
Perceived quality is further enhanced by specially treated interior trim and soft-touch padding
that covers the dashboard all the way down to its bottom edge. The airbag aperture for the
front passenger has been made invisible.
The dashboard architecture matches the front-end exterior design philosophy of the new
RX300, in being inspired by wing-like shapes. The main instrument cluster in front of the
driver is housed in a distinctive ‘Optitron’ three pod unit with a central speedometer, flanked
by tachometer and a multi-function display with fuel gauge, engine temperature and gearshift
position read-outs.
The dashboard features a distinctive brushed ‘cool metal’ panel in the centre, which is
divided into left and right halves. Its shape is elegant and the metallic finish draws attention
to the console, which houses the climate and audio controls and a seven-inch touchsensitive screen for vehicles equipped with satellite navigation system and reverse parking
monitor.
The central trim is complemented by curved Walnut or Maple wood in the lower console
containing the selector lever for the sequential automatic transmission. There are further
light wood highlights on the steering wheel, door trims and centre console box between the
front seats. The adjustable console box can either slide forwards to give the impression of a
continuous sweep from the centre console, or backwards to create a ‘walkthrough’ space
between the front seats.
CONVENIENCE
On the SE and SE-L versions, the leather-upholstered driver and front passenger seats have
eight-way electric adjustment, allowing occupants to select the ideal fore/aft seat position;
seatback (forward/backward); seat cushion tilt angle; seat cushion height (up/down). With
fabric trim, the driver's seat has eight-way adjustment and the passenger seat four-way
adjustment. The SE and SE-L also feature a memory function that will store two positions for
the driver’s seat, along with settings for the steering wheel and door mirrors. All can be
recalled at the touch of a switch on the driver’s side door trim.
The rear seats match those in the front, being designed as separate entities to highlight an
‘independent four seat’ approach. A padded central area between the outer two seats acts
as a third rear seat. Each rear seat is adjustable fore and aft by 120mm and can be reclined,
allowing all passengers to travel in great comfort. The padded central seating area
additionally folds down to create a combined armrest and storage box, with two ‘XL’ size
cupholders. Three cupholders are provided for front-seat passengers.
16
For more flexible, versatile load carrying, the three rear seat backs on the SE and SE-L
models can be folded down in a variety of combinations: 100, 80, 60, 40 or 20 per cent. With
the central (20 per cent) section lowered, long loads can extend through from the luggage
compartment between the two outer rear passengers.
A key feature of the new Lexus RX300 is the power operation of the tailgate, automatically
opening and closing at the touch of a button (SE and SE-L versions). It can also be activated
at distance using the remote key control fob. For safety, a buzzer sounds when the
automatic operation starts. Touch and motor sensors stop the door if there is any obstruction
to its closing action. If jamming by any object is detected, the Power Tailgate will
immediately move in the up direction.
To further aid convenience, the tonneau-type luggage bay cover automatically retracts as
the tailgate opens. There are 12V power outlets in the centre console and luggage
compartment, while hidden underfloor storage compartments are also accessible in the
luggage bay, simply by clicking down their pop-up lids.
A further combination of perceived quality and owner convenience is a premium illumination
scheme which lights up door handles, centre console, footwells, ignition switch and scuff
plates. The Intelligent Illuminated Entry System fitted to SE and SE-L versions uses an ECU
to coordinate the activation of the different illumination points with certain actions, such as
opening the door and inserting the key in the ignition. It is particularly helpful when getting
into or out of the vehicle at night.
Further convenience is offered by the Customised Body Electronics System. This allows the
Lexus Centre to individually programme the various ECUs to suit the owner’s personal
preferences. For example the remote door lock control system can be programmed to
respond differently to either ‘one click’ or ‘two click’ pressing of the unlock button; the hazard
warning lights can be programmed to respond to input from the remote; and the Theft
Deterrent System can be programmed to start automatically 30 seconds after removing the
key from the ignition.
LOW LEVELS OF NVH
In common with all Lexus models, the RX300 sets new standards in its class in terms of
NVH. Intensive computer modelling has achieved the best possible application of vibration
damping and noise suppressant materials to reduce engine and road noise and increase
high-frequency noise absorption.
17
Foamed urethane sponge and foamed seal material are applied to the cabin roof and pillars
to reduce wind and road noise, while a large-size dash panel silencer cuts down highfrequency noise. A dash outer silencer and bonnet silencer significantly reduce the noise
transmitted from the engine compartment.
In place of the traditional underfloor noise
damping sheets, the RX300 is the first vehicle of its type to use a new coating-type of
foamed damping material that sticks to the entire floor panel, treating it as a single acoustic
system. This gives enhanced road noise reduction, while at the same time achieving a 20
per cent reduction in the combined weight of the sound proofing materials.
ON-BOARD INFORMATION
The RX300’s advanced electronics have also made it possible to provide more features for
enhanced convenience, quality and performance. The Lexus Parking Assist Monitor,
effectively a TV camera mounted at the rear, is a unique feature among luxury SUVs. When
reverse gear is selected, an image appears on the navigation display screen in the centre of
the dashboard, helping more accurate and safer manoeuvring and reducing the risk of
collision with low-level objects.
The display can also show a composite view, with parking guidelines superimposed on the
screen to assist the driver. These guidelines include a vehicle width extension to help the
driver gauge the width of the vehicle, and a guideline indicating the likely path of the vehicle
based on the current steering position.
When specified, the same touch-sensitive seven-inch screen displays information from the
Lexus Navigation System, trip information, air conditioning controls and a calendar display
with memo registration and multi-information display.
The Lexus Navigation System uses the Global Positioning System and map data from a
DVD to pinpoint the position of the vehicle and display it on screen. The system also
provides voice instructions to guide the driver to any pre-selected destination.
Vehicles not equipped with the seven-inch touch sensitive centre screen feature a new MultiInformation Display. This LCD panel is located on the top of the centre console and provides
information about ambient temperature and trip-related data, such as average speed,
average fuel consumption, instantaneous fuel consumption, journey distance from start-up,
journey range and elapsed time.
AIR CONDITIONING SYSTEM WITH NEURAL NETWORK CONTROL
18
The RX300’s air conditioning system is the most advanced available in any SUV today. The
fully automatic system features left/right independent control allowing the driver and front
seat passenger to individually select their preferred temperature. Both cold and warm air can
now also be conducted directly to rear seat passengers via a new rear face level duct.
The system features a Neural Network Control system. This is capable of effecting complex
temperature control by simulating the way the human nervous system processes
information, similar to a human brain.
In previous automatic air conditioner systems, the ECU determined the required air
temperature and blower air volume according to fixed calculations from its sensor
information. However human sensors are more complex and influenced by the surrounding
environment. For example, a given amount of solar radiation can feel comfortably warm in a
cold climate, yet uncomfortable in a warm climate. The Neural Network Control system
collects and stores a range of data from different environmental conditions to provide
enhanced air conditioner control and comfort.
The unit is also significantly more energy efficient. Although maintaining the same power
consumption, the heater now has greater heating capacity and the air conditioner has
additional cooling capacity. Heat exchange efficiency has also been improved.
The air
conditioner unit is now more compact, with a new, super-slim evaporator and longitudinallymounted heater.
AUDIO SYSTEM: THE EXCELLENCE OF MARK LEVINSON®
A final luxury and convenience touch is a choice of advanced audio systems including a
Lexus eight-speaker system with an in-dash six-CD player and Automatic Sound Leveliser
(ASL). An 11-speaker premium audio system is also offered, developed from Lexus’s unique
collaboration with the world’s most exclusive maker of home audio systems, Mark
Levinson®. More information about this equipment can be found in the ‘Advanced Features’
chapter.
CHASSIS: ENGAGING DRIVING DYNAMICS WITH TYPICAL LEXUS
REFINEMENT
Subtle enhancements and new technology have been combined in the chassis and
suspension of the new RX300 to provide even more engaging driving dynamics in all driving
conditions. In addition, a new, optional Air Suspension System offers a still higher level of
19
performance and ride control, together with an auto-levelling function and the ability to alter
ride height through a range of 55mm.
AIR SUSPENSION: FIRST TIME IN RX300
The optional new Air Suspension System offers an even higher level of performance and
refinement. It provides greater ride control together with an auto-levelling function, along with
four operating modes by which ride height can be adjusted through a range of 55mm and
five levels: High (+30mm), Normal, Auto-low (-7.5mm), Low (-15mm) and Access Mode (25mm).
The system uses pneumatic cylinders instead of the coil springs used in a conventional
suspension design. A suspension control ECU analyses information based on the switches,
sensors, load and ride input signals to operate the height control compressor assembly, and
uses solenoid valves to control the vehicle ride height and attitude.
Three vehicle heights can be selected by operating a control switch on the dashboard: The
‘HI’ (High) mode raises vehicle height by 30mm to allow optimum ground clearance and
‘drive-through’ performance on rough roads. The ‘LO’ (low) mode lowers vehicle height by
15mm for better high speed handling, reduced body roll and improved aerodynamic
performance. The ‘N’ (Normal) mode helps produce the optimum ride comfort and
controllability in normal driving and at speeds above 62mph automatically lowers the vehicle
by 7.5mm to provide superior high-speed stability.
When the ignition is turned off, the air suspension assumes ‘Access’ mode, lowering vehicle
height by 25mm, to provide easier access or exit for driver and passengers, as well as easier
loading of cargo.
COIL SUSPENSION: FLATTER RIDE WITH IMPROVED COMFORT
An improved front MacPherson Strut suspension system includes a new coil spring rate,
shock absorber and revised suspension bushes for greater lateral force control and a
smoother ride. This is further aided by the exceptional rigidity of the new body structure.
In addition to the new components, the front suspension uses ‘Nachlauf’ geometry. This
positions the kingpin axis ahead of the axle centre, which delivers excellent straightline
stability. The steering feel is also improved by using this geometry.
The front suspension also adopts a small level of negative camber, effectively leaning the
top of each front wheel inwards, relative to the bottom of the wheel when the vehicle is
20
moving in a straight line. When the suspension is under cornering load, the change in
vehicle posture naturally reduces the ground contact camber angle of the outside front
wheel, positioning it in the optimum position to handle cornering loads.
A key component of any vehicle with MacPherson strut suspension is the suspension upper
support. In the RX300 this is designed to transmit the load applied by the spring through its
metal structure, while the rubber portion receives only the load applied through the shock
absorber. This further improves NVH suppression and suspension control, while the inclining
of the centre axis of the coil spring to the outside of the vehicle compared with the shock
absorber reduces the lateral force bearing on the shock absorber piston rod, allowing
smoother and more accurate operation.
The performance of both front and rear shock absorbers features ‘high reaction’
developments to achieve high response and high damping force at small amplitudes. They
are also enhanced by the use of multi-leaf type linear control valves, which promote more
linear damping. On the front suspension, a rebound spring is adopted to reduce body roll,
promote a flatter cornering attitude and create extra vehicle stability during cornering.
At the rear of the new RX300, a dual-link strut suspension system is used in combination
with a new, more rigid rear axle design. At the same time, there is a new layout for the coil
springs and shock absorbers, optimising the suspension geometry to achieve a flatter ride,
greater stability and controllability.
STEERING
A speed-sensitive rack and pinion steering system is used, with a responsive 3.0 turns from
lock to lock.
For further comfort and convenience the steering column is electrically
adjustable for reach and on the SE and SE-L versions is equipped with a memory function.
The upgraded power steering system used in the new RX300 creates a more linear vehicle
movement during initial steering input and improved cornering and steering response.
Internal-external tube bushings are used to mount the steering gear to the vehicle.
WHEELS AND TYRES
The RX300 runs on 225/60 R17 tyres on 17-inch diameter six-spoke alloy wheels or 235/55
R18 high performance tyres on 18-inch diameter five-spoke alloy wheels. In addition to
enhancing the vehicle’s appearance and giving optimum driver feedback and cornering
performance, these wheels allow larger ventilated front brake discs to be fitted, the diameter
21
increased from 296 to 319mm. An increase in front brake piston size and reduction of brake
pedal stroke ensure more linear and powerful braking performance.
BRAKE CONTROL SYSTEM
Braking performance is further enhanced by a multi-channel anti-lock braking system (ABS),
with Electronic Brake Distribution (EBD), Brake Assist (BA) and Vehicle Stability Control
(VSC) system.
Brake Assist interprets a quick push of the brake pedal as emergency braking and
supplements the braking power applied to maximise braking performance in conjunction with
the ABS. This overcomes the recognised problem of drivers not applying sufficient force to
the brake pedal in an emergency.
While the primary role of the ABS is to help prevent the wheels from locking when the brakes
are applied firmly or when braking on a slippery surface, EBD utilises the ABS to deliver
optimum brake force distribution between the front and rear wheels, according to driving
conditions. In addition, during simultaneous braking and cornering, EBD works with the VSC
to control the individual brake forces on the right and left wheels, helping to maintain vehicle
stability.
The VSC system also monitors the vehicle's behaviour during normal cornering. It maintains
stability by using the car’s ABS and TRC sensors to apply small amounts of asymmetric
braking, preventing the vehicle from slipping sideways as a result of a loss of traction from
either front or rear wheels during cornering.
This distribution of brake force, which in the past was performed mechanically, is now
performed by a skid control ECU. This provides much more precise electronic control for
optimum brake force, according to driving conditions.
POWERTRAIN: MORE DRIVING PLEASURE WITH GREATER FUEL
EFFICIENCY
The transversely-mounted high-performance three-litre V6 engine and full-time four-wheel
drive system used in the original RX300 have been significantly revised to boost
performance and refinement in the new model. The new generation RX300 additionally uses
an all-new five-speed, Multi-mode Automatic Transmission and electronically controlled
torque distribution between front and rear wheels for even greater efficiency.

Engine speed
(rpm)
The Lexus RX300 is powered by the most sophisticated and refined petrol engine to be
found in a sport-utility vehicle. The 2,995cc, four-cam, all-aluminium V6 remains a technical
leader in luxury SUVs by utilising a three-stage variable induction system and an active
engine mount, among other technical refinements.
The power of the RX300 has been increased to 201bhp by refinement of the intake and
exhaust systems. This figure is class-leading among competitors equipped with three-litre V6
petrol engines.
The Lexus VVT-i (Variable Valve Timing, intelligent) engine optimises valve overlap
throughout the engine’s rev range to eliminate the traditional compromises between low-end
torque and high-end horsepower. The result is an engine that develops 80 per cent of peak
torque as low as 1,600rpm for optimum pulling power and standing-start performance.
The three-stage ACIS (Acoustic Control Induction System) is a variable induction system
with three independent variation stages, as opposed to the two stages in other, conventional
systems. The use of ACIS achieves higher torque across the complete rev-range and brings
tangible improvements in terms of smoothness.
23
Fuel economy and lower emissions were identified by Lexus engineers as the key priorities
in the development of the new RX300 engine. This was the prime reason for using the 3.0litre engine for European markets, as opposed to the 3.3-litre version of the same engine
which is used in the USA.
A more precise electronic control of the fuel injection throttle system, combined with higher
gear ratios means that extra-urban fuel economy is improved from 21.7mpg for the original
RX300, to 23.2mpg for the new model, a best in class figure for luxury SUVs equipped with
six-cylinder petrol engines.
The new Lexus RX300 already complies with the strict 2005 Euro IV emission regulations.
Equally importantly, it does so without the need for performance-sapping devices such as
exhaust gas recirculation, required by many other such vehicles.
The smoothness and refinement of the V6 engine is further enhanced by the use of a fully
Active Engine Control Mount, which is controlled directly by each combustion stroke of the
engine. The technology, which was a ‘world-first’ refinement on the original RX300, uses a
solenoid-controlled diaphragm to create pulses which are equal but opposite to the engine’s
movements, to counteract vibration.
TRANSMISSION: FIVE-SPEED MULTI-MODE AUTOMATIC TRANSMISSION
A five-speed automatic transmission is used in the Lexus RX300 for the first time, combined
with an improved drivetrain in which the torque distribution between the front and rear
wheels is controlled electronically by the Traction Control (TRC), rather than the previous
mechanical control by viscous limited-slip differential. The new TRC system provides more
precise control, delivering smooth traction even when the throttle pedal is used roughly.
The Multi-mode Automatic Transmission, controlled from a dashboard-mounted shift lever
offers either full automatic operation or the opportunity to select S-mode and create the
driving feel of a sporty five-speed manual transmission vehicle.
By moving the selector from ‘D’ to ‘S’, the driver is able to sequentially shift gears with a
forward and backward movement of the shift lever, with the shift range position being
displayed on the dashboard. As a further convenience while in S-mode, the transmission
automatically returns to first gear, whenever the vehicle comes to a standstill.
In the D-mode, the transmission is optimised by the electronic throttle control system to give
quick downshifts and smooth upshifts. Extra refinement is achieved by the use of a shift
24
control programme, which minimises the shifting of gears when the driver operates the
accelerator pedal on a winding road or gradients. The engine and transmission ECUs work
together to calculate from the speed sensor signal and engine load, whether the vehicle is
travelling up or downhill.
If the electronic control module determines the vehicle is heading uphill, it will automatically
delay any upshift in the gearbox until it recognises that the ascent is complete. On a downhill
gradient, the transmission will shift down the ratios in accordance with the driver operating
the brake pedal, minimising the need for brake application.
Specifically designed to meet the needs of customers who are already used to the standards
of refinement and performance set by Lexus saloons, the RX300 four-wheel drive system is
well ahead of traditional ‘off-roaders’ in terms of driveability, comfort, efficiency and safety.
The first generation RX300 used a viscous limited-slip centre differential to transfer torque to
the wheels which have the most traction. This has been replaced in the new RX300 by a
more sophisticated and efficient electronic control system which uses the car’s TRC and
VSC systems to ensure seamless distribution of drive, even when alternate wheels would
otherwise slip.
By discontinuing the traditional limited-slip differential and concentrating on the development
of more effective traction and stability control systems, a significant weight saving has been
achieved. The TRC and VSC provide superior traction in every situation and are quicker to
react than the limited slip differential as the wheel sensors can detect even minimal wheel
slippage.
The weight saving achieved by the use of electronic control is reflected in both performance
and better fuel economy. Aligned to the decision not to include the seldom-used low-range
transfer gearbox, with its associated cost, weight and maintenance implications, the RX300
is between 200 and 300kg lighter than many of its segment rivals.
Of course, in terms of its powertrain, the new RX300 remains a true Lexus, setting new
standards in refinement, beyond the class leading standards established by the original
model. Detail developments include the use of a dynamic damper on driveshafts, along with
the straightening of the exhaust system and the driveline routes under the car, to minimise
resonance and vibration.
As hard acceleration is a principle source of vibration, the front section of the driveline is
canted forward by two degrees when the car is static to allow it to assume the optimum
25
straight line under acceleration load. Combined with the rigid, low vibration and low noise
body structure characteristics, this exceptionally refined driveline contributes to the lowest
levels of cabin noise in the vehicle’s class.
BIRTHPLACE OF THE RX300: CHANGING THE WAY OF BUILDING CARS
Production of both the original and the new generation of the Lexus RX300 is at a
groundbreaking plant in Miata in the prefecture of Kyushu, Japan’s southernmost island.
The factory came on stream in December 1992 and began RX300 production in December
1997. It was the first independent Toyota Motor Corporation plant to be established outside
the Aichi Prefecture and has set new standards in quality, efficiency and environmental
performance.
Kyushu people are renowned in Japan for their independence and rapid decision-making.
This quality is put to good use at the Kyushu plant and is a perfect expression of ‘kaizen’ – a
commitment to continuous improvement. “As no process can ever be declared perfect, there
is always room for improvement”.
Employees develop tools in-house that will make tasks easier and faster and will increase
quality. The factory is fully air-conditioned and features coordinated interior colours to create
a pleasant working environment. Noise is also carefully controlled. For example, the noise
from the 4,000-ton body-stamping machine is absorbed by a giant noiseproof cover and
372mm-thick anti-vibration springs.
Cleanliness is regarded as paramount. When the sheet metal rolls arrive at the plant, they
are kept in a dirt-free warehouse and wrapped in protective material. Before they go to the
press machine, they are carefully cleaned again to make sure there is no dust or particles
that could damage the quality of the stampings.
Robots and AGVs (automatic guided vehicles) take the completed panels to the flexible body
line. Here the stamped parts are attached by more than 360 automatic welding machines
and robots. The painting plant achieves the highest possible quality by maintaining a dustfree environment. While most processes are carried out by robots and painting machines,
the human hand and eye remain equally important. Detailed tasks and strict quality
inspections of every vehicle are conducted both visually and manually by workers.
The final assembly, which mates the mechanical and suspension components, electrics and
interior trim, attaches as many as 2,500 components to each car. The traditional production
26
line has been divided into 11 mini lines, where a team of workers manages its area
independently.
Each worker personally assures the vehicle quality in his or her own
assembling process before the car moves on to the next stage.
The assembly area aids both worker comfort and product quality by positioning each RX300
on a height-adjustable lift, which can raise or lower cars by up to 600mm to ensure the best
access for fitting components.
To foster a greater sense of achievement among the
workers, a scheduled rotation of staff between production lines allows them to acquire a
range of different skills.
Kyushu has its own recycling centre within the plant, something that is still quite rare in the
motor industry, where many waste products are still simply incinerated. In this facility drying
machines process waste paint and sludge, while crushers, condensing machines and
grinding machines reprocess and recycle other waste materials. The plant also cleans and
recycles more than 4,000 tonnes of waste water each day. The emission and energy
consumption levels for the plant are exceptionally low for a unit of this type, helped by the
use of solar power to provide energy and electricity to some buildings. These examples of
environmental commitment were decisive in the attribution of the ISO14001 certification in
1998.
The Kyushu plant was honoured with the J.D. Power Platinum World Award for product
quality in 2001 and won the Gold Award for Asia in 2002. The quality of the end product of
the plant, the new Lexus RX300, will of course speak for itself.
LEXUS RX300: TECHNICAL GLOSSARY
THREE-STAGE ACIS (ACOUSTIC CONTROL INDUCTION SYSTEM)
The Lexus RX300’s 3.0-litre V6 powerplant of the Lexus RX300 is equipped with an
innovative variable air intake system which adjusts the length of the intake manifold
according to the engine’s load and speed.
The purpose of ACIS is to improve torque throughout the rev range, particularly at low
speeds. ACIS also promotes a smoother engine operation with three independent variation
stages, compared to the two featured in most conventional systems. ACIS has been
installed
in
the
1MZ-FE V6 engine since 1998.
27
The stage variation is achieved through the control of two actuators (one in the throttle body,
the other in the intake air chamber) by the engine ECU. These actuators selectively open
and close to control the air intake route through the air cleaner hose, throttle body and intake
air chamber.
Stage 1 - heavy load, low-speed range
To suit the longest cycle of intake pulsations (at lower engine speeds), the engine ECU
closes both actuators. As a result, the air stream will take the longest route to the
combustion chamber, passing through the air cleaner hose, throttle body and intake air
chamber.
Stage 2 - heavy load, mid-speed range
To generate a suitable response in these conditions, ACIS will operate an intermediate
stage, activating only the throttle body actuator. As a result, the intake air chamber will
function as an intake manifold, shortening the intake air path compared to Stage 1.
Stage 3 – during idling, light load and high-speed range
To suit a very short cycle of intake pulsations, the two intake air control valves are opened,
allowing a quicker air supply to the combustion chamber and improving volumetric efficiency.
4WD SYSTEM WITH CONTINUOUS TORQUE SPLIT
The Lexus RX300’s full-time four-wheel drive system of Lexus RX300 constantly distributes
torque at a 50:50 ratio between front and rear axles.
Compared to that used on the first-generation RX300, the efficiency of this 4WD system has
been improved to such a level that it doesn’t require a limited-slip differential mechanism for
the centre differential or a viscous coupling-type LSD for the transfer mechanism. As a
result, the whole system is much lighter and simpler, which also adds to overall reliability.
Traction control versus limited-slip centre differential
Thanks to improvements made to the TRC (traction control) system, the new RX300’s 4WD
system can prove more efficient than the former LSD-based system in most driving
conditions.
For instance, in situations where both a front and a rear wheel are slipping, the centre
differential would prove inefficient in providing a torque split that could be converted into
traction. However, on a TRC-based system, the TRC would selectively brake these two
wheels, forcing the differentials to transfer all the torque to the wheels with most grip.
28
In addition, the TRC system is also quicker to react than an LSD mechanism, as the wheel
sensors can detect even the slightest slippage. In practice, the RX300’s 4WD system
equipped with TRC can provide continuous and instantaneous torque distribution to each
wheel.
ACTIVE CONTROL ENGINE MOUNT
To achieve low levels of noise and vibration, the Lexus RX300’s front engine mount has
been equipped with an active system, unique among vehicles in its segment and a world-first
for Lexus when it was introduced in 1998.
The Active Control Engine Mount operates during idling, at engine speeds below 900rpm.
The engine ECU sends signals synchronised to the engine speed so that the engine vacuum
can be utilised to vary the pressure of the intake air chamber in the Active Control Engine
Mount. As a result, an internal diaphragm vibrates, and, using the liquid as a medium, the
rubber mount vibrates. This vibration acts to cancel out engine vibration during idle, thus
reducing overall noise and vibration levels.
AIR SUSPENSION SYSTEM
The Automatic Vehicle Height Control continuously adjusts the vehicle height to a
predetermined level, independent of the number of passengers or load. The Air Suspension
ECU receives information from four different vehicle height sensors and can command the
system to fill or empty the pneumatic cylinders if any variation in ride height occurs.
29
The Air Suspension System can also adjust the vehicle height according to several
conditions:
Control
HI (High) Mode
Vehicle Height
N (Normal) Mode
Control
LO (Low) Mode
Vehicle Speed Sensing Control
Access Mode Control
Vehicle height variation
+ 30 mm
0 mm
- 15 mm
-7.5 mm
- 25 mm
The Vehicle Height Control can be activated using a switch in the centre console. This
allows the driver to choose between three different height settings.
On selecting Vehicle Speed Sensing Control, the vehicle’s height will automatically be
lowered by 7.5mm from the normal mode for speeds above 62mph. However, if the vehicle
height switch is set to HI and the vehicle speed is between 19 and 31mph, the Vehicle
Height Control will transfer vehicle height to N (normal) mode after 10 seconds. If the speed
happens to be higher than 31mph, the vehicle’s height will immediately be lowered to N
mode.
The Access Mode Control will lower the vehicle’s height to allow an easier access for
passengers and loading or unloading of cargo. By pressing the Access Mode button, the
vehicle’s height will be lowered by 25mm from N mode.
AUTOMATIC LIGHT CONTROL SYSTEM
The new Lexus RX300 is equipped with a system that automatically turns on headlights and
taillights in poor light conditions. This system is particularly useful in daytime driving on roads
with tunnel sequences.
The Automatic Light Control System is enabled when the AUTO position is selected on the
light control switch. The level of ambient light is detected by an automatic light control sensor
integrated into the air conditioning system’s solar sensor.
This sensor is located on the driver side, above the instrument panel. An embedded photo
diode produces variable electrical resistance proportional to the amount of ambient light.
This allows the system to monitor the light level continuously.
CUSTOMISED BODY ELECTRONICS SYSTEM
30
The Customised Body Electronics System enables the settings of up to 40 electronic vehicle
functions to be adjusted to suit each owner’s individual requirements. This task can be
performed on request by all Lexus Centres.
The range of features which can be customised include the remote locking system, theft
deterrent system, electric windows, wipers, intelligent illuminated entry system, light control
system, sunroof, air conditioning and power tailgate.
THORAX-ABDOMEN-PELVIS (TAP) SIDE AIRBAG
A new generation of side airbags is being launched in the new Lexus RX300. They have a
bigger capacity and so protect a wider area of the passenger’s body. Instead of protecting
just part of the abdomen or torso, they can simultaneously protect the torso, abdomen and
pelvis.
To achieve this superior level of side-impact protection, these airbags have a capacity at
least six litres greater than most others available on the market.
The TAP side airbags are offered as standard equipment in the new RX300 and,
complemented by the vehicle’s strong body construction and the curtain shield airbags, they
provide top levels of injury protection in the event of side impacts.
INTELLIGENT ADAPTIVE FRONT-LIGHTING SYSTEM (AFS)
Introduced in the Lexus RX300 as a world-first for SUVs, Intelligent AFS can greatly improve
levels of active safety during night-time driving. By swinging the projector headlight (low
beam) to the inner side of the cornering direction, Intelligent AFS ensures a wider
illumination area.
The Intelligent AFS ECU receives information from the steering wheel angle sensor and
speed sensor. This lets the system acknowledge the steering angle, steering direction and
speed of the vehicle and calculate the ideal swivel angle for the projector beam.

INTELLIGENT ILLUMINATED ENTRY SYSTEM
This system can control several different light sources in the interior in order to provide the
passengers with the right type of illumination at the right time.
The lighting sources are: interior light (roof), key illumination, scuff plate light, inside door
handle light, footwell light and combination meter ring illumination.
Each one is turned on and off in coordination with different actions, such as unlocking doors,
opening and closing the driver’s door and turning the ignition on.
This special illumination system and the combination of all light sources represent a step
forward in convenience and add to the premium look of the RX300’s cabin.
KNEE AIRBAG
In a frontal collision, the 16-litre SRS knee airbag will inflate and protect the driver’s knees
from hitting the lower parts of the dashboard. The knee airbag will also help keep the driver’s
body in the correct position for optimum protection from the seatbelt and front airbag.
The Lexus RX300 is the first SUV in the world to feature a knee airbag, fitted as standard.
LED (LIGHT EMITTING DIODE) STOP LIGHTS
In the new Lexus RX300, LED technology is used in the design of the stop lights. The
replacement of the conventional light bulbs by LED lights achieves three distinct benefits:
Safety: LED elements light up 10 times faster than lamp bulbs, 2 to 15 milliseconds as
opposed to 150 to 200msec. This represents something like six metres of reaction time at
62mph – a distance that could be crucial in avoiding a collision.
Fuel efficiency: LEDs use less energy than conventional filament bulbs. They account for up
to a 0.8 per cent improvement in fuel consumption.
Design: LEDs are more compact and give the design team more freedom when designing
the rear lights.
LEXUS PARKING ASSIST MONITOR
The new Lexus RX300 is the first vehicle in its segment to be equipped with an optional
parking auxiliary system which can make reverse parking manoeuvres simpler and safer.
32
The system consists of a small rear-view camera discreetly installed in the handle of the
tailgate. It transmits images to a seven-inch LCD centre display when reverse gear is
selected. Special software can generate guiding lines on the screen to provide assistance.
The television camera uses a wide-angle lens that can capture objects that are almost
directly below the rear bumper.
Display Status
The Lexus Parking Assist Monitor can function in three different modes:

Guiding lines off: the driver receives only the images from the rearview camera, with no
guiding lines.

Manual Assist Mode: the driver can have the assistance of guiding lines for normal
reversing manoeuvres.

Serial (parallel) Parking Assist Mode: this mode projects guiding lines on the screen to
help the driver in parallel parking manoeuvres.
The guiding lines are generated by the camera’s ECU. It receives information from the
steering wheel sensor and from a vehicle speed sensor to adapt the guiding lines to the
different phases of the parking manoeuvre.

MARK LEVINSON® AUDIO SYSTEM
The new Lexus RX300 SE-L is equipped with an audio system developed by Mark
Levinson®, the world’s most exclusive audio systems specialist. The equipment designed by
Mark Levinson® for Lexus is of the same exceptional quality as its world-renowned home
entertainment systems.
The specification of the Mark Levinson® audio system includes:

AM/FM tuner

Cassette player with Dolby noise reduction

In-dash six-CD changer

CD Text function

24-bit Digital Signal Processor

Automatic Sound Leveliser (ASL)

Custom engineered speakers (11)

Tri-amplified audio

240W, 8-channel amplifier
The quality of the RX300 cabin itself also contributes a great deal to the achievement of
such superb sound quality. The interior of the car is well insulated, with a low level of
ambient noise. Several components have a high level of rigidity and so eliminate unwelcome
resonance.
The audio system for models with leather interiors has been subjected to a specific tuning
process in order to deliver all the desired sound qualities.
MULTI-MODE AUTOMATIC TRANSMISSION
For the first time, all versions of the Lexus RX300 are equipped with a five-speed automatic
transmission. The system is designated as Multi-mode as it allows the driver to choose
between automatic and sequential gear changes.
Manual sequential shifts can be made by moving the gear lever to the “S” position. From
there, gears can be selected by moving the shift lever forwards ("+" position) or backwards
("-" position). The gear selected is indicated in a display in the central instrument cluster.
36
The five-speed automatic transaxle incorporates a number of other features:

NEURAL NETWORK CONTROL SYSTEM
In conventional automatic air conditioning systems, the ECU determines the required outlet
air temperature and blower air volume using a calculation formula based on information
received from sensors.
A human’s sensorial network is much more complex, though, which means that sometimes
the settings used by the A/C do not provide the best comfort for passengers. For instance, a
given amount of solar radiation can feel comfortably warm in a cold climate or extremely
uncomfortable in a hot environment.
The answer to this problem was the development of an air conditioner ECU that can actually
simulate the complex human sensorial network that regulates the body’s thermal functions
and sets the standards for thermal comfort.
To begin with, a great deal of information was stored in the ECU, based on how several
people would react to variations in temperature. This information is then used as a basis for
the Neural Network Control, which consists of three layers of neurons.
37
The input layer neurons receive information on elements such as outside temperature,
amount of sunlight and cabin temperature. They will then output this data to the intermediate
layer neurons. Based on this information, they adjust the strength of the links between the
neurons. The sum of these links is then calculated by the output layer neurons in the form of
details such as required outlet temperature, solar correction, target airflow volume and outlet
model control volume. The air conditioner ECU will then control the servo motors and the
blower motor in accordance with these parameters.
The new Lexus RX300 is the first luxury SUV in the world to use such a sophisticated air
conditioning system.
POWER TAILGATE
The Lexus RX300 is the first luxury SUV in Europe to be equipped with an electric-powered
tailgate.
This system, available as standard equipment on SE and SE-L grades, automatically opens
or closes the vehicle’s rear door at the press of a button or using the key remote controller.
For safer operation, the system is equipped with a warning buzzer and touch sensors. This
sounds when the automatic operation starts and the touch sensor detects any foreign object
obstructing the door, commanding the system’s ECU to stop and reverse the closing action.

WATER REPELLENT GLASS COATING
The front door windows feature a special water-repellent coating that significantly improves
visibility in heavy rain. Water droplets slide easily across the glass surface instead of
gathering together on the window and impairing outward vision.
NEW LEXUS RX300: MUCH MORE FOR YOUR MONEY
COST OF OWNERSHIP
Both in terms of on-the-road price and cost of ownership, the RX300 leaves its rivals
standing. The competition has had five years to sharpen up its act, but still lags behind when
it comes to delivering anything like the kind of comfort, convenience and safety equipment
package Lexus owners enjoy as standard for a remarkable on-the-road price.
Take your pick of the premium marques and you will discover that, to specify an equivalent
vehicle to match even the entry-level RX300, owners will need to spend thousands of
pounds on extra-cost options. Taking a package of what Lexus has identified as priority
items for luxury SUV owners, it enjoys a price advantage of up to £3,510 compared to direct
rival models from BMW, Mercedes-Benz, Volvo and Land Rover. And that’s without taking
into account the fact that the Lexus comes with some features money just can’t buy where
other brands are concerned.
The BMW X5 3.0i is a prime example. Even before you consider the specification detail, the
car is more than £4,000 more expensive to buy than the RX300. Watch that figure soar as
you add on £1,220 for automatic transmission, £250 for a CD autochanger, £545 for xenon
headlamps and a wallet-busting £1,495 for electric seat adjustment.
The picture is similar with the Mercedes-Benz ML 350. You will need to find more than
£3,300 just to pay for a CD autochanger, trip computer, xenon headlamps and electric seat
adjustment. That’s on top of a list price that’s already more than £3,700 higher than that of
the Lexus.
And where the Land Rover Discovery XS V8 is concerned, there is no hope of side or curtain
airbags, xenon lights, stability control, or a host of other standard Lexus features, no matter
how much money you are prepared to pay. What’s more, even with its poor specification and
39
options list, the Discovery will still set you back more than £2,500 above the price tag of the
RX300.
The RX300’s advantage is not confined to just those features listed here for comparison
purposes. All versions of the car are equipped with a driver’s knee airbag, while the SE and
SE-L versions offer a tailgate that opens and closes at the touch of a button. The flagship
SE-L further benefits from the Adaptive Front-lighting system, which swivels the headlights in
line with steering input to improve forward illumination through bends, and a rear-view
camera with a colour display screen integrated into the vehicle’s Lexus Navigator satellite
navigation system.
Full details of how the new Lexus RX300 measures up against its key market rivals are
provided in the following tables.

For company car drivers, the appeal of the new RX300 is even greater. Lined up against its
key luxury SUV rivals, it has almost all of them beaten on monthly tax charges. The monthly
Benefit in Kind taxation, based on carbon dioxide emissions of 288g/km, works out at just
more than £335 for the Lexus – almost £90 less than for a BMW X5 3.0i and more than £80
less than for a Mercedes-Benz ML 350.
The Jeep Grand Cherokee 4.0 Limited has a marginally better tax performance, but the
‘saving’ of a little more than £4 will quickly disappear when you take the car’s inferior fuel
economy into account: Jeep quotes a combined cycle figure of 17.7mpg for the 4.0-litre V8powered Grand Cherokee, while the RX300’s clean and efficient 3.0-litre V6 engine is
capable of 23.2mpg under the same conditions.
The Association of British Insurers (ABI) has awarded the RX300 and RX300 SE insurance
group 15E, the same classification as the outgoing model. The SE-L version is in Group
16E.
The new Lexus RX300 requires servicing every 10,000 miles (Health & Safety Check) with
major servicing required at 20,000 mile intervals. RX300 is sold with 3 years/60,000 miles
warranty with 3 year paint and 12 year anti-perforation warranties.
The new Lexus RX300 will be available in three versions when UK sales begin on 16 May.
The on-the-road prices and grading structure is as follows:
RX300
RX300 SE
RX300 SE with Lexus Navigator
RX300 SE-L
RX300 SE-L with Wood Finish Pack
£28,955
£33,000

£37,705
£38,105
* These prices include the additional £5 VED charges introduced from 1 June 2003.
RESIDUAL VALUE
The new Lexus RX300 luxury SUV may have a higher top speed than its predecessor but it
looks certain to be even slower to depreciate. The car has been set an unusually high threeyear residual value of 50 per cent by leading vehicle financing and fleet solutions provider
ALD Automotive.
“This is a sector-leading car, offering improved levels of driveability and safety,” says ALD’s
Procurement Manager Peter Rossiter. “It will be a very sought-after used vehicle at the end
of contract – as is the current model. Lexus dealers are actually snapping up any used
46
examples now. There’s a shortage on the marketplace because this is a niche rather than a
volume product, and that will help the car retain its value.
“The RX is a superb product but a figure as high as 50 per cent is quite uncommon in the
SUV sector,” says Rossiter of the three-year/60,000-mile residual. “It will be more of a retail
than a corporate prospect and in terms of our fleet mix we’re happy as long as there’s a
market at the end of contract. Certainly the desirability factor on the RX is pretty good and
that’s good news as far as risk management is concerned.”
The valuation was welcomed by Andy Simpson, Lexus’s National Corporate Sales Manager:
“I’m delighted that the RX300 has achieved a 50 per cent residual, it’s a major statement of
faith in the brand.
“What’s more, the existing RX300 is already being moved up by CAP to 42 per cent in
March, which is a strong basis for the launch of the new car. All the old models were sold
three months before the arrival of the new one. This is a deliberate policy designed to create
a launch platform and order bank for the new car,” he says.
The run-out strategy has already paid off: by the end of March, 250 new RX300s were
already on order.
