Formerly the Grand-Am Koni Challenge Series, the Continental Tire Sports Car Challenge is the premier proving ground for many of today’s automotive manufacturers by using an endurance racing format to test their mettle. The series competes at historic tracks in the United States and Canada, featuring some of the best production car drivers from around the world. The series complements the Rolex Sports Car Series by using race cars that are actual production vehicles.
Continental Tire Sports Car Challenge cars are often purchased directly from the showroom floor with only minimal racing modifications allowed to enhance safety and performance. Two classes of race cars compete on the track at the same time during Continental Tire Sports Car Challenge—Street Tuner (ST) and Grand Sport (GS)—with drivers competing for top honors in their specified class, as well as the overall win. Continental Tire Sports Car Challenge cars are classified by weight, engine size and model.
