As modern motor racing is centered on modern technology with a lots of corporate sponsors and politics involved, historical racing tends to be the opposite. Because it is based on a particular era it is more hobbyist oriented, reducing corporate sponsorship and politics. Events are regulated to only allow cars of a certain era to participate. The only modern equipment used is related to safety and timing. A historical event can be of a number of different motorsport disciplines. Notably some of the most famous events of them all are theGoodwood Festival of Speed and Goodwood Revival in Britain and Monterey Historic in the United States. Championships range from grass root Austin Seven racing to the FIA Thoroughbred Grand Prix Championship for classic Formula One chassis.
