In motor racing, BTC Touring (BTC-T) was a set of new regulations for the British Touring Car Championship (BTCC) introduced in the 2001 BTCC, after the demise of the Supertouring category.
The cars were based on standard bodyshells but were allowed significant modifications to turn them into race cars and differentiate them from the Super Production class that would run alongside BTC Touring in the 2001 BTCC.
A year after the regulations began, the European Touring Car Championship launched its Super 2000 regulations. As the latter allowed manufacturers to have their cars seen internationally, most major companies opted for it, resulting in small grids for the BTCC. In 2004, TOCA allowed Super 2000 cars to compete, with rules designed to equalise the performance of both classes. BTC-T cars were eventually made ineligible to win the main championship from 2007.
The 2010 season was meant to be the last year BTC Touring cars were eligible to enter the championship; however, they were allowed to compete for one more season in 2011, with their base-weight +50 kg on 2010.
