The 2009 Honda S2000 is a compact two-seat roadster that is available in two versions -- base and CR. The base S2000 includes a power convertible soft top with a glass rear window, 17-inch alloy wheels, xenon headlights, leather upholstery, full power accessories, air-conditioning and a CD player. There are no significant factory options for the S2000, but a number of dealer-sourced accessories, including a removable hardtop, are available.The CR model is a racetrack-focused variant aimed at die-hard enthusiasts. Air-conditioning and the sound system have been removed to reduce weight, though they can be added back as options. Other casualties of the CR's diet include sound insulation and the power soft top, the latter being replaced by the removable aluminum hardtop. The CR also receives some unsightly but effective aerodynamic spoilers, dark gray wheels with wider rear tires, even sportier suspension tuning, a quicker steering ratio, a sport-tuned muffler and fabric seats with suede inserts. Add it all up and the topless CR is 99 pounds lighter than the standard S2000 (51 pounds lighter with the hardtop installed). Some of the base model's options are also available on the CR.
