Stock car racing is a high-speed form of automobile competition.

Drivers compete on oval tracks or winding road courses. While the sport began in the southern United States, it is now a global phenomenon. You can find stock car racing in Canada, Mexico, Brazil, Argentina, and Chile. It also has a presence in Australia, New Zealand, and the United Kingdom. The sport is defined by intense speed and highly specialized machinery. Today, the premier level of professional racing is the NASCAR Cup Series.

Modern racing vehicles are built for extreme performance. They are no longer the "stock" cars of the past. These machines use a body template to resemble current street models. However, the chassis and running gear are custom-built for racing. They do not resemble ordinary automobiles at all. Most top-level cars use naturally aspirated V8 engines. These engines produce massive power, often between 860 and 900 horsepower.

On superspeedway tracks like Daytona International Speedway, these engines allow for incredible velocities. In 2007, driver Russ Wicks set a speed record in a NASCAR-spec Dodge Charger. He achieved this at the Bonneville Speedway.

The history of the sport is tied to the Prohibition era of the 1920s. During this time, moonshine runners needed to outrun authorities. They upgraded their vehicles to increase speed. They kept the cars looking ordinary to avoid attracting attention. Eventually, these runners began organizing races to challenge one another. In the early 1930s, these informal gatherings became organized events. By 1948, Bill France Sr. recognized a need for unified rules. He organized a meeting at the Streamline Hotel. This meeting led to the formation of NASCAR to regulate the sport.

In the early years, NASCAR used a rule called homologation. This meant every car had to use parts available to the general public. To qualify, a car model had to have sold at least 500 units through dealers.

In these early days, cars were so similar to street versions that drivers often drove them to the track. The 1949 Oldsmobile Rocket V-8 was a major success during this period. It was the first postwar modern overhead valve engine available to the public. This created a "win on Sunday, sell on Monday" culture. Manufacturers realized that racing success could drive high car sales.

As technology advanced, the relationship between manufacturers and racing changed. In the 1960s, carmakers produced "special edition" models to satisfy homologation rules. These were high-performance versions of base models. For example, Ford sold enough aerodynamic "sport-roof" Galaxies to qualify them for racing. In 1963, NASCAR restricted engines to a maximum displacement of 7.0 liters. This was also the limit for using only two valves per cylinder. Manufacturers like Ford, Chrysler, and General Motors competed fiercely to build the best engines. This era saw the rise of legendary drivers like Richard Petty.

Petty won 27 of 48 races in 1967 using a Plymouth Belvedere.

Aerodynamics became a major focus as speeds increased. Some cars, known as "aero-cars," featured radical body shapes. The Dodge Daytona used a pointed nose and a wing for stability. This was necessary to remain stable at speeds over 200 miles per hour.

However, these high speeds caused safety concerns. NASCAR feared that tire technology could not handle the extreme forces. They changed the rules in 1970 to require more cars be sold to the public. This was meant to delay the use of extreme aerodynamic bodies. Eventually, NASCAR adopted restrictor plates to limit engine power and manage top speeds.

Today, stock car racing is a massive professional industry. The sport underwent a major shift in 1972 when R.J. Reynolds became the major sponsor. This changed the name to the Winston Cup. This infusion of money transformed the entire nature of the sport. Since 1992, the cars have moved further away from true street models. They now feature sleeker shapes and grounded type spoilers. While they look like the cars in a showroom, they are highly engineered racing tools. The sport continues to evolve through better engineering and changing safety regulations.
