The United States version of the WEC motorsports testing laboratory The International Motor Sports Association (IMSA) created in 1969 by John Bishop and NASCAR President Bill France Sr.

 

The IMSA Weathertech SportsCar Championship is North America's premier sports car racing series, with Prototype and GT styles of vehicles competing in IMSA racing. Both the Prototype and GT styles feature a Pro and a Pro-am class, meaning there are four classes of IMSA racing on the track simultaneously, all vying for the lead in their respective classes.

 

Prototype and Grand Touring are the two automobile classes in the WeatherTech SportsCar Championship. The Prototype Class features the quickest and most technologically advanced cars in North America and a driver lineup comprised entirely of professional drivers. Daytona Prototype International (DPi), Le Man's Prototype 2 (LMP2), and Le Man's Prototype 3 (LMP3) are the three different types of prototypes (LMP3). 

GT Le Mans (GTLM) and GT Daytona are the two Grand Touring classifications (GTD). Factory-backed efforts dominate in the DPi and GTLM classes. The LMP2, LMP3, and GTD classes are available for privateer client teams.
