Formula 1000

Not to be confused with the publisher of services for life scientists Faculty of 1000.

F1000 cars in 2013.

Formula 1000 (F1000) is a class of open wheel formula racing with professional and amateur series worldwide. Formula 1000 gets its name from the 1000 cc (1.0 L) super-bike engine used to power a single seat, open wheel race car with fully adjustable wings and suspension. ^[1]

Currently in the United States, F1000 runs in SCCA under the FA (Formula Atlantic) class (it was previously run as the FB class prior to 2020) or under SCCA Pro Racing with the North American Formula 1000 Championship.

Formula 1000 cars are priced between $40,000 to $75,000. SCCA rules also allow conversion of an existing Formula car (e.g., FC) to meet F1000 requirements. ^[2]

Formula 1000 race cars can reach speeds higher than 274 km/h (170 mph) and experience as much as 3 Gs of downforce ^{[ citation needed ]} on brakes and corners.

There is a similar but distinct category in the UK called F1000, run by the 750 Motor Club.

Manufacturers

Manufacturers of Formula 1000 race car conversions are listed below in alphabetical order. A Formula 1000 conversion involves the modification of an existing Formula 1000 race car to meet current Formula 1000 rules. One of the major changes involved in a conversion is replacing the original engine and drive train with a 1000 cc super-bike engine using a chain drive train. Other modifications may include chassis frame changes, suspension changes and the addition of an aerodynamics package consisting of front and rear wings with a floor pan diffuser.
