Jon Sibal posted these pictures of the Mugen CR-Z GT testing at Twin Ring Motegi. The car is slated to compete in the GT300 class of the Japanese Grand Touring Championship. The people who saw the car in person said the engine was relatively quiet, so it’s probably turbocharged. Honda has already stated that the CR-Z GT has a racing hybrid system. Honda likes to put their racing campaigns that use possibly risky drive train technology under the Mugen name in case they’re not as successful as they hoped it would be. The same thing happened with the Mugen Shinden electric motorcycle. Head over to Jon Sibal’s Blog to see the rest of the pictures. The CR-Z won’t be the only hybrid in the GT300 class. Toyota is also campaigning a Prius hybrid race car.
