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 this, meaning that the BTCC suffered from small grids. 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 would be 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.[1]
