As it turns out the Mugen CR-Z is no the only hotted-up version of the car in the works. It also has an RR sister which is even hotter, at least visually.

The RR was revealed at the Goodwood Festival of Speed and ran up the hill, but there is not much details available on its technical specs. Mugen themselves only talk about the car’s visual features which include front aero bumper, front aero fender, side spoiler, rear aero bumper, rear wing, 18″ wheels. The RR looks much better than the non-RR version and is closer to the original sketches.

The interior of the RR also features the same range paint as the exterior, garnished with various carbon parts.

Even though this car must have the worst rear visibility, it looks great and we hope they finally get around making it. Honda is of course denying any plans to put either of these Mugen prepared CR-Zs into production and refer to them just as “Design Study Model”.
