The Classes

IMSA Prototype Challenge Presented by Mazda, an International Motor Sports Association (IMSA) Development Series, enters its 12th season in 2017. The series provides thrilling action and grooms drivers for future IMSA Weather Tech SportsCar Championship competition in the Prototype and Prototype Challenge classes.
 
The series features global race car constructors Élan Motorsport Technologies backed by Mazda power, and offers racers from around the world the opportunity to compete at historic venues like Sebring International Raceway and Road Atlanta.
 
The Prototype Challenge mission is two-fold: present an opportunity for semi-professional race car drivers to compete in a world-class environment, while also providing an avenue for drivers to move up the ladder into the Prototype classes in the IMSA Weather Tech SportsCar Championship. Offering more avenues for potential professional race care drivers and a more professional atmoshpere for the semi-professional race car driver is the Prototype Challenge way of advancing the competition of sportscar racing.
