At the 2009 Tokyo Auto Salon (TAS), Mugen surprised everyone by unveiling this extreme NSX. Called the RR, it comes almost four years after production of the regular model was cancelled.

The biggest modification was made to body with new carbon fibre and aluminum panels that both widens and lengthens the standard NSX body. Attached to this is a new fixed rear wing, front splitter, rear diffuser and hood scoop.

As one would expect the powertrain and chassis were also upgraded but at the show the engine was not functional. Mugen said that the RR was strictly a showcar to celebrate their upcoming anniversary.
