Legends car racing is a style of race car, designed primarily to promote exciting racing and to keep costs down. The body shells are 5/8-scale replicas of American automobiles from the 1930s and 1940s, powered by a Yamaha motorcycle engine. The sanctioning body for legends car racing is called INEX. INEX stands for inexpensive racing. Legends cars are a “spec” series, meaning all cars are mechanically identical, with the exception of three styles of car (standard coupe, 34 coupe, and sedan) available with 10 types of body styles.
