The Civic Sedan Si went on sale on November 1st 2007.
The car was previously showed at the SEMA (Specialty Equipment Market Association) show that year and was basically a Civic Si with 4 doors. This compact sedan went on sale in 2008 for the Canadian market and was some 60 pounds (27 kg) heavier than the coupe version, but the additional weight was offset by a better weight distribution balance (60/40 front-rear for the sedan versus 61/39 percent for the coupe version). The car came with sport tuned suspension, an i-VTEC engined that revved up to 8,000 rpm and several exclusive interior features like suede leather sport seats and red backlit gauges.
