Production car racing : Production car racing or known in the US as showroom stock, is an economical and rules restricted version of touring car racing, mainly to restrict costs.

One-make racing: Similar to production car racing, as races can lead to an unfair advantage by teams, the differences of one-make racing is rules are mainly centered on one-manufacturer, sometimes on one-model, which is a misnomer to the tag.

Stock car racing : One of the most famous tracks was the old Riverside International Raceway in Riverside, California. Stock car racing, the North American equivalent to touring car racing, is the most-popular form of auto racing (in terms of viewership) on that continent. NASCAR also runs the Busch Series (a junior stock car league) and the Craftsman Truck Series (pickup trucks).

Rallying : A Ford Escort Cosworth, driven by Malcolm Wilson on a stage rally. Rallying, or rally racing, involves two classes of car. The modified Group A, but road legal, production based cars and the Group N Production cars compete on (closed) public roads or off-road areas run on a point-to-point format where participants and their co-drivers “rally” to a set of points, leaving in regular intervals from start points.

Sports car racing : In sports car racing, production versions of sports cars and purpose-built prototype cars compete with each other on closed circuits. The races are often conducted over long distances, at least 1000 km, and cars are driven by teams of two or three drivers (and sometimes more in the US), switching every now and then. Famous sports car races include the 24 Hours of Le Mans, the 24 Hours of Daytona and the 12 Hours of Sebring.
