An evolution of the dominant Shelby GT350R-C, the Mustang GT4 was developed by Multimatic Motorsports for Ford Performance as a turn-key package for global GT4-level competition. The car was unveiled at the 2016 SEMA tradeshow, ahead of its competition debut during the 2017 Daytona 24 weekend. The Mustang GT4 would go on to claim five wins and ten podiums in its first year of IMSA Continental Tire SportsCar Challenge and Pirelli World Challenge competition.
