IMSA SportsCar Championship

The Monterey Sports Car Championship is a sports car race held annually at WeatherTech Raceway Laguna Seca by the International Motor Sports Association (IMSA). The event began in 1950 as a race on the roads of Pebble Beach, California. In 1951, it was added to the new SCCA National Sports Car Championship. When Laguna Seca Raceway was built in 1957, the races moved there. The event fell dormant after the National Championship was discontinued in 1957, but was revived by the SCCA's new United States Road Racing Championship in 1963. The race fell dormant again in 1969, and was revived in 1973 with the IMSA GT Championship.

The 2022 Chevrolet Detroit Grand Prix (formally known as the Chevrolet Detroit Grand Prix presented by Lear) was a sports car race held at The Raceway on Belle Isle in Detroit, Michigan on June 4, 2022. It was the sixth round of the 2022 IMSA SportsCar Championship and the fourth round of the 2022 WeatherTech Sprint Cup.
