Automobile racing (also known as auto racing, motor racing, or car racing) is a sport involving racing automobiles. Auto racing began in 1895, and is now one of the world's most popular sports.
With auto construction and racing dominated by France, the French automobile club ACF staged a number of major international races, usually from or to Paris, connecting with another major city in Europe or France.
These very successful races ended in 1903 when Marcel Renault was involved in a fatal accident near Angouleme in the Paris-Madrid race. Nine fatalities caused the French government to stop the race in Bordeaux and ban open-road 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.
Many series follow the Group N regulation with a few exceptions. There are several different series that are run all over the world, most notably, Japan's Super Taikyu and IMSA's Firehawk Series which ran between the 1980s to 1990s all over the United States.
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. A rally is typically conducted over a number of 'special stages' of any terrain, which entrants are often allowed to scout beforehand at reduced speeds compiling detailed shorthand descriptions of the track or road as they go. These detailed descriptions are known as 'pace notes'. During the actual rally, the co-driver reads the pace notes aloud (using an in-helmet intercom system) to the driver, enabling them to complete each stage as quickly as possible. Competition is based on lowest total elapsed time over the course of an event's special stages, including penalties.
