A go-kart, also written as go-cart (often referred to as simply a kart), is a type of small sports car, close wheeled car, open-wheel car or quadracycle. Go-karts come in all shapes and forms, from non-motorised models to high-performance Kart racing.
Karting is a type of racing in which a compact four-wheel unit called a go-kart is used.
Art Ingels created the first motorised go-kart in Los Angeles in 1956.
are a popular form of non-motorised go-kart. These are karts which are propelled by gravity and are often simplistic, homemade and used for either recreational or competitive use. These are often referred to as soapbox cars in North America, however other regional variations such as Billy cart (Australia) are common.
Other forms of non-motorised go-karts (ie. ) may also be propelled by means such as bicycle pedals (such as in the form of a velomobile).
are available, requiring only that the batteries of the karts be plugged into an array of chargers after each run. Since they are pollution-free and emit no smoke, the racetracks can be indoors in controlled environments. Electric karts powered by lead-acid batteries can run a maximum of 20–30 minutes before the performance is affected, while those powered by lithium batteries may last up to 2 hours on a single charge. Some karts have been fitted with hydrogen fuel cells. Forze hydrogen karts High-performance electric go-karts for amusement parks and indoor tracks may have external electronic controls in the event of an accident or other hazards, in which the track attendant or the race referee can remotely slow down or stop all vehicles on the track via radio control. This external control can also be used to limit young riders to a slow operating speed, while a race consisting only of adults is permitted a higher speed. These controls can be applied to both electric and combustion-engine karts.
In some countries, go-karts can be licensed for use on public roads often referred to as street tracks. Typically there are some restrictions; in the European Union, a go-kart modified for use on the road must be outfitted with headlights (high/low beam), tail lights, a horn, indicators, and an engine not exceeding .
Outdoor Kart circuits can offer low-speed karts strictly for amusement (dedicated chassis equipped with low powered four-stroke engines or electric motors), or faster, more powerful karts, similar to a racing kart, powered by four-stroke engines up to and, more rarely, by 2-stroke engines, but designed to be more robust for rental use. Typically, outdoor tracks are also used for traditional kart races.
Indoor kart tracks can be found in many large cities in different parts of the world. These tracks are often located in refurbished factories or warehouses, and are typically shorter than traditional outdoor tracks. Indoor karts are usually powered by a four-stroke gasoline engine producing anywhere from , or sometimes by an electric motor. Many tracks offer competitive races and leagues. At the top level, an Indoor Karting World Championship (IKWC) exists.
There is a separate category of go karts in the powersports industry that includes off road go karts. These are similar to a miniature dune buggy. Off road go karts typically feature large tires, a full roll cage, heavy duty suspension, and features to protect the riders from wind and mud. There are no longer any American made offroad buggy brands due to legal issues, so all brands will come from China. Trailmaster is the leading off-road go kart brand with a wide range of models and features. Other brands of offroad go karts also come from China and include Coleman, Tao Tao, Kandi, and Hammerhead (previously built by Trailmaster).
