Since its debut in 2002, the RSX has carved a solid niche in the sports coupe segment, and with the important "tuner" market. Available in two distinct models-the sporty RSX and the high-performance RSX Type-S-this sports coupe serves as an important point of entry for the brand, introducing youthful performance enthusiasts to the Acura line-up of precision-crafted performance luxury vehicles. The RSX has won an assortment of industry awards including being named to Car and Driver's "10 Best" and Ward's 10 Best Engine's lists. With their high-performance engines, abundant luxury features, advanced safety and security systems, and innovative cockpit and body designs, the RSX and RSX Type-S have set a bold standard of driving excitement and refinement in the sports coupe segment.
The RSX is powered by a 16-valve, DOHC i-VTEC 2.0-liter four-cylinder engine that produces 160 horsepower at 6500 rpm and 141 lb-ft. of torque at 4000 rpm. The RSX features either a 5-speed manual transmission or an available 5-speed Sequential SportShift automatic transmission. For 2005, modifications to the intake, exhaust and emissions systems were made to the Type-S model's 16-valve, DOHC i-VTEC 2.0-liter four-cylinder engine to boost power to 210 horsepower at 7800 rpm (up from 200 hp at 7400 rpm on the previous model) and 143 lb-ft of torque at 7000 rpm (up from 142 lb -ft at 6000 rpm). The Type-S comes exclusively with a close ratio 6-speed manual transmission. To complement the engine performance gains, the final gear ratio of this 6-speed manual was lowered by 8.6 percent to provide quicker acceleration. Single cone carbon synchronizers replace double cone brass synchronizers on fifth and sixth gears to provide a more direct shift feel and reduce mechanical losses in the transmission.
