The Honda Civic Mugen Si is the first real factory Mugen vehicle to be offered in the United States. When Honda pulled the wraps off the production car last month, all we saw were a few static studio images. That's been remedied, as the automaker has unleashed a mess 'o new shots, showing the trick, tuned Civic Si carving up a track. Limited to 1,000 units, the Mugen Si gets a more aggressive suspension tune, the body kit shown, and lighter wheels. Power is the same as the standard Civic Si, but we have a feeling the Mugen will hustle around the track in less time. It goes on sale this fall. All the new photos have been added to the gallery below. Enjoy.
