Stock car racing began in the United States during the Prohibition era (1920-1933), primarily as an informal competition among moonshine runners who modified their cars to outrun law enforcement on rural roads. After Prohibition ended, the drivers' need for speed and mechanical skills found a new outlet in organized races, which formalized into the NASCAR (National Association for Stock Auto Racing) league in 1948, founded by Bill France Sr.
The roots are firmly planted in the Appalachian region. Bootleggers needed vehicles that appeared ordinary but could handle the heavy load of moonshine and, more importantly, outrun police cars on winding mountain paths. They became experts at modifying engines, suspensions, and chassis. These modifications—engine tuning for more power and chassis reinforcement for durability—laid the foundation for the performance enhancements we see in racing today.
After World War II, these drivers began to test their skills and machines against each other in informal races on weekends. Recognizing the potential for a organized spectator sport, Bill France Sr. organized a meeting of drivers, mechanics, and promoters in Daytona Beach, Florida, in 1947. This led to the founding of NASCAR on February 21, 1948. The first strictly stock car race was held on the Daytona Beach road course on June 19, 1949, and was won by Red Byron. The term "strictly stock" meant the cars were supposed to be identical to those sold to the public, a concept that has evolved dramatically but remains a core part of the sport's identity.
