When was NASCAR formed?
Stock car racing
When NASCAR was first formed by France in 1948 to regulate stock car racing in the U.S., there was a requirement that any car entered be made entirely of parts available to the general public through automobile dealers. Additionally, the cars had to be models that had sold more than 500 units to the public. This is referred to as "homologation". In NASCAR's early years, the cars were so "stock" that it was commonplace for the drivers to drive themselves to the competitions in the car that they were going to run in the race. While automobile engine technology had remained fairly stagnant in World War II, advanced aircraft piston engine development had provided a great deal of available data, and NASCAR was formed just as some of the improved technology was about to become available in production cars. Until the advent of the Trans-Am Series in 1967, NASCAR homologation cars were the closest thing that the public could buy that was actually very similar to the cars that were winning national races.
Bill France Sr.
France knew that promoters needed to organize their efforts. Drivers were frequently victimized by unscrupulous promoters who would leave events with all the money before drivers were paid. On December 14, 1947 France began talks with drivers, mechanics and car owners at the Ebony Bar at the Streamline Hotel at Daytona Beach, Florida that ended with the formation of NASCAR on February 21, 1948. They discussed uniform rules, insurance coverage and guaranteed purses.
