2015 Rejects Touring Car Championship season

The 2015 season of the Rejects Touring Car Championship occured 17 years after the first, but was only the second in the history of the championship. The original RTCC had ceased to exist after just two rounds of the 1998 season, due to the conviction and imprisonment of series supremo Herrmann Mann on drugs possession and use charges. Impromptu champions Team Ultimate returned to contest the 2015 season (albeit with manufacturer backing from BMW), along with many of the teams that contested the inaugral season. However, the established teams were joined by new teams, most notably West Cliff Racing and Douglas-Cliff Racing. Team Wales, Zakspeed, Martini Nissan Racing, Equipe de Corse Belge, Astral Motorsport, The Good Will Out (Race You) and Taiwan Motorsport did not return to compete in 2015.
