Auto racing (also known as car racing , motor racing , or automobile racing ) is a motorsport involving the racing of automobiles for competition. Auto racing has existed since the invention of the automobile. Races of various sorts were organised, with the first recorded as early as 1867. Many of the earliest events were effectively reliability trials, aimed at proving these new machines were a practical mode of transport, but soon became an important way for competing makers to demonstrate their machines. By the 1930s, specialist racing cars had developed. There are now numerous different categories, each with different rules and regulations.

The first prearranged match race of two self-powered road vehicles over a prescribed route occurred at 4:30 A.M. on August 30, 1867, between Ashton-under-Lyne and Old Trafford, a distance of eight miles. It was won by the carriage of Isaac Watt Boulton. Internal combustion auto racing events began soon after the construction of the first successful gasoline-fueled automobiles. The first organized contest was on April 28, 1887, by the chief editor of Paris publication Le Vélocipède , Monsieur Fossier. It ran 2 kilometres (1.2 mi) from Neuilly Bridge to the Bois de Boulogne. On July 22, 1894, the Parisian magazine Le Petit Journal organized what is considered to be the world's first motoring competition, from Paris to Rouen. One hundred and two competitors paid a 10-franc entrance fee. The first American automobile race is generally held to be the Thanksgiving Day Chicago Times-Herald race of November 28, 1895. Press coverage of the event first aroused significant American interest

Open-wheel racing edit The two most popular varieties of open-wheel road racing are Formula One and the IndyCar Series. F1 is a worldwide series that runs only street circuit and race tracks. These cars are heavily based around technology and their aerodynamics. The speed record was set in 2005 by Juan Pablo Montoya hitting 373 km/h (232 mph). Some of the most prominent races are the Monaco Grand Prix, the Italian Grand Prix, and the British Grand Prix. The season ends with the crowning of the World Championship for drivers and constructors. In single-seater (open-wheel), the wheels are not covered, and the cars often have aerofoil wings front and rear to produce downforce and enhance adhesion to the track. In Europe and Asia, open-wheeled racing is commonly referred to as 'Formula', with appropriate hierarchical suffixes. In North America, the 'Formula' terminology is not followed (with the exception of F1). The sport is usually arranged to follow an international form

In many types of auto races, particularly those held on closed courses, flags are displayed to indicate the general status of the track and to communicate instructions to competitors. While individual series have different rules, and the flags have changed from the first years (e.g., red used to start a race), these are generally accepted. Flag Displayed from start tower Displayed from observation post The session has started or resumed after a full course caution or stop. End of hazardous section of track. Full course caution condition for ovals. On road courses, it means a local area of caution. Depending on the type of racing, either two yellow flags will be used for a full course caution or a sign with 'SC' (Safety car) will be used as the field follows the pace/safety car on track and no cars may pass. However, if the safety car gives a green light, then the cars behind can pass the safety car (lapped cars only). Local caution condition —no cars may pass at t

The worst accident in racing history is the 1955 Le Mans disaster, where more than 80 people died, including the French driver Pierre Levegh.

In auto racing, the racing setup or car setup is the set of adjustments made to the vehicle to optimize its behaviour (performance, handling, reliability, etc.). Adjustments can occur in suspensions, brakes, transmissions, engines, tires, and many others. Aerodynamics edit Aerodynamics and airflow play big roles in the setup of a racecar. Aerodynamic downforce improves the race car's handling by lowering the center of gravity and distributing the weight of the car equally on each tire. Once this is achieved, fuel consumption decreases and the forces against the car are significantly lowered. Many aerodynamic experiments are conducted in wind tunnels, to simulate real life situations while measuring the various drag forces on the car. These "Rolling roads" produce many wind situations and direct air flow at certain speeds and angles. When a diffuser is installed under the car, the amount of drag force is significantly lowered, and the overall aerodynamics of the vehicle is
