Colt EV

The in-wheel motor test car, Colt EV, is based on the standard compact vehicle, Colt. After removing the combustion engine, fuel tank and transmission, two in-wheel motors were fitted to the rear wheels and powered by a floor-mounted lithium-ion battery system. Mitsubishi Motors will use the on-road testing program to identify and resolve any problems unique to the in-wheel motor vehicle, including any deterioration in road holding and ride comfort due to increases in un-sprung weight, as well as reliability and durability issues in the in-wheel motor system and its peripheral components (suspension, wheels, tyres). Rigorous proving ground tests are now being conducted on the Colt EV. The test car is scheduled to undergo a tuning program with independent control of drive torque and braking force for left and right wheels to improve dynamic performance. After receiving vehicle type certification, Colt EV will undergo verification testing on public roads.
