Pure Pleasure: Highly Efficient 1.4-Liter Turbo in the New Astra

All-aluminum: four-cylinder gasoline unit of the latest engine generation

Instant throttle response: Dynamic response and ample performance

Pure high-tech: Direct fuel injection and turbocharging for highest efficiency

Milestone: Eight millionth engine from Szentgotthárd a 1.4-liter turbo
Rüsselsheim. The full name of the new Opel engine is 1.4 ECOTEC Direct Injection Turbo
and it will celebrate its world premiere in the new Opel Astra at the International Motor
Show in Frankfurt (IAA) in September. The four-cylinder turbocharged unit with central
direct fuel injection will be available in two outputs, 92 kW/125 hp and 110 kW/150 hp. This
combination links the new all-aluminum engine to the recently introduced 1.0 ECOTEC
Direct Injection Turbo known from Opel ADAM and Corsa. In fact, the new 1.4-liter fourcylinder engine is the big brother of the one-liter, three-cylinder unit that has been praised
by the trade press since its introduction in the ADAM ROCKS and the new Corsa
generation. Both engines are members of the so-called small gasoline engine family – a
group of high-tech engines with three or four cylinders and a displacement below 1.6 liters.
They are key players in the biggest engine offensive in Opel’s history which will see 17
new engines brought to market from 2014 to 2018.
Best in class: The new Opel four-cylinder engine purrs like a kitten
A lot of attention was paid to dynamic responsiveness and high performance while curbing
fuel consumption during the development phase of the 1.4-liter turbo. The engine delivers
maximum torque of up to 245 Nm very early. The maximum power is available between
2,000 and 3,500 rpm – an outstanding torque plateau. Perfect conditions for driving
pleasure in combination with efficiency. According to preliminary data, the powerful turbo
with Start/Stop will consume a mere 4.9 liters of gasoline per 100 kilometers in the
combined cycle (114 g/km CO2). The 1.4-liter turbo will therefore be able to outperform

even two-liter gasoline engines in all performance characteristics and replace them. The
engineers once again paid close attention to low noise levels and vibration behavior during
the development of the 1.4-liter turbo – just like they did for the one-liter, three-cylinder
unit. The engine block was constructed with resonance reduction in mind, the oil pan split
into two, the integration of the cylinder head into the exhaust manifold is noise protected, a
sound absorbing cam cover has been designed, the high-pressure injection valves
decoupled and the timing chain trimmed for quiet concentricity.
“Our new turbocharged 1.4-liter, four-cylinder engine with central direct injection is part of
the newly designer small gasoline engine family and embodies its attributes ‘powerful,
efficient and cultivated’. The all-aluminum unit is not only environmentally friendly but also
sets new standards in driving comfort,” said Christian Müller, VP GM Powertrain
Engineering Europe.
The lightness of being: The new degree of efficiency
Based on its construction, the new 1.4 ECOTEC Direct Injection Turbo adds less weight to
the car. The aluminum engine block alone weighs ten kilograms less than the cast-iron
block of the current 1.4-liter turbo, making it the perfect match for the new, highly efficient
Opel Astra. Apropos efficiency, this is where the 1.4 turbo can really show its technical
advantages: to make the engine as light as possible, the crankshaft is hollow cast, the oil
pump drive is especially low friction and the oil pump works in two pressure levels
accordingly. The entire engine is designed for low friction oils with a viscosity grade of 5W30. All of these measures ensure fuel efficiency of the highest standard.
While the three-cylinder Opel units are typical representatives of engine downsizing
(smaller, lighter, more efficient), the Opel engineers speak of “rightsizing“, i.e. the perfect
balance between low load and high load efficiency, when talking about the new 1.4-liter
four-cylinder engine.
Milestone engine from Szentgotthárd
The 1.4 ECOTEC Direct Injection Turbo is manufactured in the Opel Flex Plant in
Szentgotthárd. And it is already responsible for setting a new milestone for the Hungarian

plant. The eight millionth engine from Szentgotthárd left the production line today and it
was, of course, an all-aluminum, four-cylinder unit that will make its debut in the new Opel
Astra from September.
“We have world class flexible engine plant in Hungary and it plays a key role in our product
strategy. Congratulations and a huge thanks to the entire team here – eight million engines
is something to be very proud of and I am sure that we will be able to celebrate even more
milestones here in the future,” said Peter Christian Küspert, Vice President Sales &
Aftersales Opel Group, who attended the celebrations along with Marc Schiff, Executive
Director Manufacturing Opel/Vauxhall Europe, members of the Hungarian government and
local officials.
