An open-wheel car is a car with the wheels outside the car's main body, and usually having only one seat. Open-wheel cars contrast with street cars, sports cars, stock cars, and touring cars, which have their wheels below the body or inside fenders. Open-wheel cars are built both for road racing and oval track racing. Open-wheel cars licensed for use on public roads, such as the Ariel Atom, are uncommon, as they are often impractical for everyday use.
The Japanese Super Formula Championship is a formula racing series held primarily in Japan. It is considered to be the pinnacle of single-seater racing in Japan or Asia as a whole, making it one of the top motorsport series in the region. The series is sanctioned by the Japan Automobile Federation (JAF) and managed by Japan Race Promotion (JRP). As of 2024, Super Formula is the second fastest racing series in the world, after Formula One.
Formula racing, also known as open-wheel racing in North America, is any of several forms of open-wheeled single-seater motorsport. The origin of the term lies in the nomenclature that was adopted by the FIA for all of its post–World War II single-seater regulations, or formulae. The best known of these formulae are Formula One, Formula E, Formula Two, Formula Three, regional Formula Three and Formula Four. Common usage of "formula racing" encompasses other single-seater series, including the IndyCar Series and the Super Formula Championship.
Formula Ford, also known as F1600 and Formula F, is an entry-level class of single-seater, open-wheel formula racing. The various championships held across the world have historically been an important step for many prospective Formula One drivers. Formula Ford has traditionally been regarded as the first major stepping stone into formula racing after karting. The series typically sees career-minded drivers enter alongside amateurs and enthusiasts. Success in Formula Ford can lead directly to other junior formula series such as a Formula Renault 2.0 and Formula Three, or F1 Academy for female drivers, and previously the W Series, prior to the series folding.
The IndyCar Series, currently known as the NTT IndyCar Series under sponsorship, is the highest class of American open-wheel car racing in the United States, which has been conducted under the auspices of various sanctioning bodies since 1920 after two initial attempts in 1905 and 1916. The series is self-sanctioned by its parent company, IndyCar, LLC., which began in 1996 as the Indy Racing League (IRL) and was created by then Indianapolis Motor Speedway owner Tony George as a competitor to Championship Auto Racing Teams (CART). In 2008, the IndyCar Series merged with CART's successor, the Champ Car World Series and the history and statistics of both series, as well as those from its predecessors, were unified.
The USF2000 Championship Presented by Continental Tire is an American racing series using an American variation of the Formula Ford standard, "F2000", that resumed operation for the 2010 season.
