Not green coloured race cars, but eco friendly ones. Nissan will bring its LEAF NISMO RC to Le Mans while Honda will campaign its CR-Z hybrid race car. They won’t be challenging Audi and Peugeot for the win though; the eco racers will do their thing in a support event called Le Mans Vers Le Futur or Le Mans of the Future, which is reserved for EVs and hybrids.

The LEAF RC (RC stands for Racing Competition) is a 2011 New York show car that’s fully battery powered. Its full carbon fibre monocoque bodywork contains a battery pack, electric motor and inverter located in a mid-ship position. The 80kW AC synchronous motor generates 107 hp and 280 Nm, good for 0-100 km/h in 6.85 seconds and a top speed of 150 km/h. Nissan says that it can run for 20 minutes under racing conditions.

Honda’s entry is less green, but more evocative. Developed by Honda Performance Development (HPD), the racing arm of American Honda, it was first seen at last year’s SEMA show in Las Vegas. While still an IMA hybrid, the 1.5L internal combustion engine has been turbocharged to make 200 hp and 237 Nm. It’s paired to a six-speed manual gearbox.

Other expected entries are the Peugeot EX1 (see Nurburgring video here) and the Audi e-tron Spyder.
