{{Main|Production car racing}}

Production-car racing, otherwise known as "showroom stock" in the US, is an economical and rules-restricted version of touring-car racing, mainly used to restrict costs. Numerous production racing categories are based on particular makes of cars.

Most series, with a few exceptions, follow the [[Group N]] regulation. There are several different series that are run all over the world, most notably, Japan's Super Taikyu and [[International Motor Sports Association|IMSA]]'s Firehawk Series, which ran in the 1980s and 1990s all over the United States.
