The Honda S2000 is an open top sports car that was manufactured by Japanese automobile manufacturer Honda, from 1999 to 2009. First shown as a concept car at the Tokyo Motor Show in 1995, the production version was launched on April 15, 1999 to celebrate the company's 50th anniversary.
The Honda S2000 was notable for its exceptional specific power output of about 124 hp per litre, or about two horsepower per cubic inch, the highest of any mass production, naturally aspirated engined car.
The S2000 was introduced in 1999 for the 2000 model year and was given the chassis designation of "AP1". It features a front mid-engine, rear-wheel-drive layout.
The engine is mated to a six-speed manual transmission and Torsen limited slip differential. The S2000 achieved what Honda claimed as the highest specific output of a normally aspirated production automobile engine in the world.
