Michelin Pilot Challenge

The Michelin Pilot Challenge is a grand touring and touring car racing series run by the International Motor Sports Association. Originating from the Canadian Motorola Cup, the series was taken over by Grand-Am in 2001 to become the Grand-Am Cup following the demise of rival IMSA's Firehawk series of similar rules in the US. KONI became series sponsor for the start of the 2007 season when the series became known as the KONI Challenge Series, before renaming once more prior to the start of the 2009 season as the KONI Sports Car Challenge. The series name was once again changed for the 2010 season to Continental Tire Sports Car Challenge. In 2019, the series rebranded again after Michelin was selected to become the new official tire supplier of the series.

The Continental Challenge was the support series for Grand-Am's premier offering, the Rolex Sports Car Series. In 2014, the series became the support series for the United SportsCar Championship (now known as the IMSA SportsCar Championship) upon the merger of the Rolex Series and the American Le Mans Series.
