TheHonda S2000 is a sports car that was manufactured by the Japanese automaker Honda Motor Company. Its front mid-engine, rear wheel drive layout (FMR Layout) gives 50:50 weight distribution, reduces the moment of inertia and, hence, improves the vehicle's handling. It was launched in April 1999 and was created to celebrate the company's 50th anniversary. The S2000 is named for its engine displacement of 2 L, carrying on in the tradition of the S500, S600, and S800 roadsters of the 1960s. Several revisions were made throughout the car's lifetime, including changes to the engine, gearbox, suspension and interior and exterior. Officially two variants exist: the initial launch model was given the chassis code AP1, while the AP2 designation was given to vehicles produced from mid-2003 onwards. Production of the S2000 ceased in June 2009.
