Acura RSX Type-S
From Acura press: 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 2.0-liter 4-cylinder engine in the high-performance RSX Type-S model adds a high-performance version of the i-VTEC system and a fixed, high-volume intake manifold. To make the Type-S even more exciting to drive for 2005, the Type-S engine receives substantial enhancements to its intake and exhaust systems as well as high performance camshafts to boost horsepower from 200 at 7400 rpm to 210 at 7800 rpm and increase torque from142 lb-ft. at 6000 rpm to 143 lb-ft. at 7000 rpm.
In keeping with Acura's proven commitment to the environment, both the RSX and Type-S engines meet strict Low Emission Vehicle-II (LEV-II) tailpipe emissions standards. Engine, fuel tank and catalytic converter modifications made for 2005 have lowered evaporative emissions by 75 percent to achieve a LEV2 Evaporative Emissions rating.
The RSX Type-S is available exclusively with a short-throw 6-speed manual transmission. The final gear ratio has been lowered by 8.6 percent for 2005 to complement the additional horsepower and provide enhanced acceleration. Designed to be compact and lightweight, the 6-speed has also been engineered to provide the lightning-quick shift action of a race car transmission.
Synchronizers (triple cone on gears 1 and 2, double cone on gears 3 and 4, and new for 2005, single cone carbon on gears 5 and 6) help reduce shifting load for a light, responsive feel. The Type-S also includes a short-throw clutch with a torsion mechanism that considerably reduces gear rattle.
The 210 horsepower RSX Type-S uses the same high-performance a three rocker arm VTEC design as the NSX, to vary the lift and duration of both the intake and exhaust valves for maximum power output. At lower rpm, the valves follow low lift, short duration camshaft profiles to help boost low-end torque. Above 5,800 rpm, the intake and exhaust valves are operated by high-lift, long-duration cam profiles, for maximum high rpm horsepower.
