 TCR cars are eligible to compete in the Super Taikyu Series starting from the 2017 season.The Pirelli World Challenge allowed TCR-based cars in their TC class for the 2017 season, and will introduce a TCR-only class in 2018.Unlike the IMSA Continental Tire SportsCar Challenge Series in the United States, which also is TCR-based for two or four hour races, the World Challenge races are shorter (no more than 50 minutes for a typical event) and are single-driver races.
