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.
There are numerous notable series that are run all over the world, including the Porsche Supercup, a supporting series for Formula One.
There are single-chassis single seater formulas such as Formula BMW, although they are not regarded as one-make racing.
