Stock car racing's history traces to Prohibition era moonshiners. They had to upgrade their cars to get away from authorities but had to do so without raising suspicion. NASCAR races can be in excess of 200 miles per hour when race track conditions allow it which only extremely high end sportscars can do (NASCAR engines are up to 900 horsepower).

By definition, they are cars that look like they're consumer cars but inside they're made to be powerful racing vehicles.
