The Kwik Fit British Touring Car Championship is a touring car racing series held each year in the United Kingdom, currently organised and administered by TOCA. It was established in 1958 as the British Saloon Car Championship and was renamed as the British Touring Car Championship for the 1987 season. The championship, currently running Next Generation Touring Car regulations, has been run to various national and international regulations over the years including FIA Group 2, FIA Group 5, FIA Group 1, FIA Group A, FIA Super Touring and FIA Super 2000. A lower-key Group N class for production cars ran from 2000 until 2003.

Next Generation Touring Car, also known as NGTC and by its Fédération Internationale de l'Automobile (FIA) designation TCN-1, is an FIA and TOCA specification and classification for production based race cars. The specification covers national level touring car racing. The goal of the limited choices in engines and parts in the NGTC classification is to allow more manufacturers and privateers to race by reducing the cost of a competitive car and to reduce reliance on the increasingly expensive Super 2000 equipment. The only significant differences between different models is the external body shells and the use of front- or rear-wheel drive; the suspension, brakes and transmissions are common to all cars, and engines are of uniform performance.
