The 2006 Civic launches in the U.S. this fall and will include a 4-door sedan, 2-door coupe and Si Coupe, Hybrid and a natural gas version, the GX.
The Si Coupe concept is powered by a 200 hp, 16-valve, DOHC, I-VTEC engine with an 8,000 rpm redline. Getting power to the road is helped by a helical-type limited slip differential.
Other Si features are 18-inch wheels and tires, 4 wheels discs, cross-drilled rotors and 4-piston Brembo calipers.
