The ALMS also created a new class of competitors, known as GT2S, designed to allow racing cars based on production vehicles which had seats for four in a coupe or sedan body style. Cars of this type were now allowed by ACO rules, but IMSA agreed that these cars would not be eligible for Le Mans entry even if they won Petit Le Mans or the season championship. These cars however would be competitively equal to the GT2 class and would compete accordingly with them. The long time BMW factory supported effort of Team PTG announced their return of the BMW M3 to the series, while Lexus announced their intentions to bring a new purpose built racing car built off of the IS. Rumors also speculated that Cadillac could bring their CTS-V SpeedGT program to the series. However, come the beginning of the season, neither Lexus nor Cadillac showed, leaving the BMW M3 as the only true GT2S competitor. The GT2S notion was shelved midseason.
