A 2.2-liter four-cylinder engine mated to a six-speed manual transmission is equipped to the S2000, producing 237 horsepower and 162 pounds-feet of torque. The S2000 has a stiff suspension, and comes with a molded top cover (body-colored hardtop optional) and leather-trimmed bucket seats. All-disc anti-lock brakes come standard. The CR trim (which stands for ?Club Racer?) is also available in 2009, with standard aluminum hardtop, specially designed aerodynamic front spoiler and rear wing, upgraded suspension, and cloth seats with synthetic suede trimmings. The air conditioning and radio are optional and for additional weight savings the sound insulation, spare tire and jack, and convertible soft top have been removed on the CR. The 2009 model is a carryover from 2008.
