Super 2000 regulations are an FIA specification and classification for production based race cars, used in both touring cars and rallying.
The main goal of S2000 was to reduce the costs of a competitive car, therefor enticing more manufacturers and privateers to compete. The regulations were first introduced to the British Touring Car Championship in 2004.
An S2000 car must be derived from a production model of which 2500 must have been produced within the past 12 months. The car must also have a naturally aspirated, 2-litre engine maxing at 8500rpm for 4 cylinders, 8750rpm for 5 cylinders and 9000rpm for 6 cylinder.
Circuit racing S2000 cars must be two-wheel drive, however all-wheel drive is permitted for rally machines.
Gearbox are also a spec part, with a 6 speed sequential gearbox, or a 5 speed MT gearbox maintaining original gear ratios. McPherson supply the front and rear suspension for S2000 cars, and no electronic driver aids are allowed. Cars must cost a maximum of €168,000 (£144,700 approx.).
The British Touring Car Championship still use these regulations, although they are now the secondary class of racing, below the new NGTC regulations. Drivers in the S2000 class are competing for the Jack Sears Trophy, given to the driver with the highest number of S2000 wins throughout the season.
