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.^[1] It was based on the "2 litre Touring Car Formula" created for the British Touring Car Championship (BTCC) in 1990.^[2] The FIA organised a World Cup for the category each year from 1993 to 1995, and adopted the term "Super Tourer" from 1995.^[3]

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 because of the loosely regulated aerodynamics required the team to invest resources equivalent as a professional Formula 1 team, and the 8,500-rpm speed limit required the team to use extremely unusual construction in engine modifications to allow the engine to break through more than 300 horsepower.

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.
