The original Trans-Am Series dissolved in 2006, but returned to action in 2009 with tube frame TA1 and TA2 divisions racing with production-based TA3-American and TA3-International divisions. In addition, the SCCA continues to provide a major support series for Trans-Am. This series, known as the SCCA World Challenge, consists of a one-hour race for each round, combining three classes: GT (Chevrolet Corvette, Aston Martin DB9, etc.), "GTS" (Acura TSX, BMW 3 Series, etc.; replaced the former touring car class), and Touring Car (a "showroom stock" class similar to Grand Am's Continental Challenge). The Trans Am series returned in 2009, but has yet to establish a television contract.
