The IMSA WeatherTech SportsCar Championship is a sports car racing series based in the United States and Canada that is organized by the International Motor Sports Association (IMSA). It offers Cadillac engineers a chance to totally rethink the boundaries of what a racecar can be. Season after season, they create unique models that take to the track and show off Cadillac’s legendary power and performance.


Just like in the World Challenge circuit, the innovations found in the Protoype models are tailored to daily driving and make their way into production models like the ATS-V and CTS-V.
