Supertouring

Super Touring, Class 2 or Class II was a motor racing Touring Cars category defined by the Fédération Internationale de l'Automobile (FIA) for national touring car racing in 1993. It was based on the "2 litre Touring Car Formula" created for the British Touring Car Championship (BTCC) in 1990. The FIA organised a World Cup for the category each year from 1993 to 1995, and adopted the term "Super Tourer" from 1995.

Super Touring replaced Group A as the norm in nearly every touring car championship across the world, but escalating costs, and the withdrawal of works teams caused the category to collapse in the late 1990s. The cars looked like regular production road cars, while expensive changes had to be made to provide space for racing tyres inside the standard wheel arches.

An example for this was the German Super Tourenwagen Cup (STW) series, which ran from 1994 to 1999, filling a void left after the end of the 2.5-litre V6-powered Deutsche Tourenwagen Meisterschaft (DTM) in 1996. In 2000, the Deutsche Tourenwagen Masters (keeping the 'DTM' acronym) resumed with 4.0-litre V8-powered cars.

The Super Touring cars were required to be a minimum of 4.20 metres (13.8 ft) in length, with four doors, effectively requiring a small family saloon car as a minimum. No more than 2 litres engine capacity, or six cylinders were permitted, and the engine was required to be normally aspirated. Only two wheels could be driven and steered. For homologation, initially at least 2500 units of the model used must have been produced. In 1995, in a bid to counter the increasing numbers of homologation specials this was increased to at least 25,000 units.
