When we looked at the MiEV Evolution two years ago, it was sporting a tri-motor, 322-hp (240-kW) powertrain, which was modified to four motors and 536 hp (400 kW) last year. This year, the MiEV Evolution continues to evolve, packing 603 hp (450 kW) of power potential in its motor four-pack. Each motor is a high-output version of the electric power plant in the production i-MiEV.
The structure around the powertrain has also been improved, starting with a lighter tube-frame chassis with new materials. The front-end has been aero-optimized with a redesigned spoiler and carbon cowl. The race car's Super All-Wheel Control AWD system has been reworked for better handling and traction control, and the tires increased in size to 330/680-18.
