Honda is currently prepping a new performance version of the Civic sedan that’s set for release in the Japan this September. Based on the already sporty Type R, the new Honda Civic Mugen RR was transformed after undergoing a power upgrade and weight reduction program in collaboration with the help of its Mugen racing division.

Power is up 15hp over the standard Type R, producing 240hp at 8,000rpm and 160lb-ft at 7,000 revs. The jump comes from modifications to the intake system and new cams as well as high-flow exhaust. Weight has been cut back with the replacement of some panels with carbon-fiber and aluminum, down 10kg once again over the standard Type R.

Other enhancements include Bridgestone Potenza tires designed specifically for the Mugen RR, a new sports suspension and uprated brakes. Inside, the car gets Recaro bucket seats with unique Mugen RR labeling. Only 300 cars will be produced, and all will be limited to Honda’s Milan Red finish.
