DAYTONA BEACH, Fla. – Since 2018, the IMSA Michelin Pilot Challenge has included the highly competitive Touring Car (TCR) class, featuring sophisticated four- and five-door race cars from world-class manufacturers powered by turbocharged engines up to 2.0 liters. As part of the agreement, WSC has been solely responsible for establishing the Balance of Performance (BoP) for TCR race cars everywhere in the world. “It remains understood that the only applicable Balance of Performance for any TCR car is the one issued by WSC,” said IMSA President John Doonan. “Through the provision of our agreement, the IMSA technical team has increased the vehicle weight across the TCR class to create the desired class separation between TCR and the Grand Sport (GS) class. Beginning in 2021, WSC and IMSA will work together to jointly develop a specific BoP for endurance TCR races.
