One-make racing

See also: One-Design

One-make, or single marque, championships often employ production-based cars from a single manufacturer or even a single model from a manufacturer's range. There are numerous notable one-make formulae from various countries and regions, some of which – such as the Porsche Supercup and, previously, IROC – have fostered many distinct national championships. Single marque series are often found at club level, to which the production-based cars, limited modifications, and close parity in performance are very well suited. Some of the better-known single-make series are the Radical European Masters, John Cooper Mini Challenge, and Clio Cup, and at a more modest budget, Ginettas, Caterhams, BMWs, and MX5s. There are also single-chassis single seater formulae, such as Formula Ford, Formula Renault, Formula BMW, and Formula Vee, usually as "feeder" series for "senior" race formula (in the fashion of farm teams).
