Another interesting concept car on display at the Tokyo Auto Show is the Mitsubishi i MiEV Sport.

Effective use of energy in the i MiEV (Mitsubishi innovative Electric Vehicle) Sport is achieved by installing an auxiliary solar panels on the roof, a power-generating fan inside the front grill, and regenerative braking functions to recover energy when the car is slowing down. Much of the lighting is by bright, power-saving LEDs, including in the rear combination lamps and vehicle interior, and the efficiency of the air conditioning is enhanced by the use of heat-absorbing window glass. In addition, Green Plastic - Mitsubishi Motors’ unique plant-based resin technology - is used wherever possible for interior components in another nod to the environment.
