Maximum speed
Japan proposed to use Maximum speed in
R68 .
Maximum speed means:
For electric vehicle, the highest average
value of the speed, which the vehicle can
maintain twice over distance of 1 km.
Further discussion is necessary to
finalize vehicle classification.
Phone meeting will be held after
