Grand Touring Prototype (GTP) The newest and most technologically advanced Prototype race car takes to the track for the first time in 2023, featuring a common hybrid powertrain for all entries that takes kinetic energy gained in braking and stores it in batteries for later use when needed.

Four manufacturers – Acura, BMW, Cadillac and Porsche – are set to usher in this new era of sports car racing. The class name “GTP” stands for Grand Touring Prototype and absolutely invokes a popular and competitive time in IMSA history, but the modern teams and sophisticated new makes will undoubtedly create their own updated storylines.

The GTP prototypes on Daytona International Speedway’s high banks today are the most sustainable race cars competing in North America. Every car will use a single-source hybrid powertrain developed by IMSA and its partners at the Automobile Club de l’Ouest (ACO) and suppliers Bosch, Williams Advanced Engineering and Xtrac.
