The base RSX came standard with the majority of convenience features expected for this class of car. Highlights included automatic climate control, power windows and mirrors, keyless entry, cruise control, a CD player and a moonroof. A smooth-revving four-cylinder was standard, and it came mated to either a five-speed manual transmission or a five-speed automatic. The base RSX initially produced 160 horsepower, but new SAE horsepower ratings in 2006 changed the number to 155. Leather seating was the only option.
.The RSX Type-S added an in-dash six-CD changer, standard leather seating, 17-inch wheels, a more firmly tuned suspension and more powerful brakes. The Type-S also had a four-cylinder engine tuned to produce extra horsepower (200 hp, later increased to 201). A six-speed manual was the only choice for a transmission.
The RSX is somewhat familiar as a redesigned Integra. The current version has either a 160 or a 200 hp four-cylinder power plant, with the latter coming standard in the Type S. The more powerful engine makes its horses partly through an advanced valve timing technology, which shifts into high performance mode at 6,000 rpm.
