GT World Challenge America is a North American auto racing series launched in 1990 by the Sports Car Club of America. It has been managed by the SRO Motorsports Group since 2018, and has been sanctioned by the United States Auto Club since 2017.
The series functions as the highest level of SRO Motorsports America race weekends, supported by the Pirelli GT4 America, GT America, Toyota GR Cup North America, TC America, and McLaren Trophy America series. A GT World Challenge America race weekend consists of two 90 minute races held exclusively for GT3-class race cars, though it has been confirmed that the format will change to a single three hour race per weekend beginning in 2026.
