NASCAR stock cars are specially designed vehicles used in NASCAR racing events. Unlike regular cars, these stock cars are built for high performance, featuring powerful engines and aerodynamic designs to enhance speed and handling on the track. They typically weigh around 3,200 pounds and can reach speeds exceeding 200 miles per hour. The cars are based on production models but are heavily modified for racing. Each vehicle is equipped with safety features, such as roll cages and fire-resistant materials, to protect drivers during high-speed collisions. NASCAR stock cars compete in various races, including the famous Daytona 500.
