Auto racing is a motorsport involving the racing of automobiles for competition. In North America, the term is commonly used to describe all forms of automobile sport including non-racing disciplines.
An outboard motor is a propulsion system for boats, consisting of a self-contained unit that includes engine, gearbox and propeller or jet drive, designed to be affixed to the outside of the transom. They are the most common motorised method of propelling small watercraft. As well as providing propulsion, outboards provide steering control, as they are designed to pivot over their mountings and thus control the direction of thrust. The skeg also acts as a rudder when the engine is not running. Unlike inboard motors, outboard motors can be easily removed for storage or repairs.
Kart racing or karting is a motorsport discipline using open-wheel, four-wheeled vehicles known as go-karts or shifter karts. They are usually raced on scaled-down circuits, although some professional kart races are also held on full-size motorsport circuits. Karting is commonly perceived as the stepping stone to the higher ranks of motorsports, with most Formula One drivers—including Ayrton Senna, Michael Schumacher, Fernando Alonso, Kimi Räikkönen, Lewis Hamilton, Sebastian Vettel, Nico Rosberg, and Max Verstappen—having begun their careers in karting.
A V16 engine is a sixteen-cylinder piston engine where two banks of eight cylinders are arranged in a V configuration around a common crankshaft. V16 engines are less common than engines with fewer cylinders, such as V8 and V12 engines. Each bank of a V16 engine can be thought of as a straight-eight, a design that can be inherently balanced. Most V16 engines have a 45° bank angle.
A snowmobile, also known as a snowmachine, motor sled, motor sledge, skimobile, or snow scooter, is a motorized vehicle designed for winter travel and recreation on snow.
Sprint cars are open-wheel race cars, designed primarily for the purpose of running on short oval or circular dirt or paved tracks. Historically known simply as "big cars," distinguishing them from "midget cars," sprint car racing is popular primarily in the United States and Canada, as well as in Australia, New Zealand, and South Africa.
OK-Junior is a kart racing class for top drivers aged 11 to 15.
The Rotax Max 125 Engine is a two-stroke 125 cc (7.6 cu in) engine designed by Rotax, part of Bombardier Recreational Products (BRP), to provide cost-effective but high speed kart racing. Built in Austria, the engine is liquid cooled, equipped with a balance shaft, integrated water pump, electric starter and centrifugal clutch. Its combination of onboard electric starter and centrifugal clutch simplifies its operation. This concept is called TaG (Touch-and-go).
Superkart is a form of motorsport road racing that uses karts on long circuits. The bigger difference between a superkart and most other forms of kart is that they have full aerodynamic bodykits, as well as having a longer wheel base than sprint chassis, and are generally raced on car circuits over 1,500 metres in length. The power unit, most often but not exclusively two-stroke 250 cc engines, can be specially designed kart engines or production motorcycle engines with either five- or six-speed sequential manual gearboxes. Owing to their high top speed and superb cornering ability, a superkart's aerodynamic bodywork includes a front fairing, larger sidepods, and a rear wing. They use either 130-or-150-millimetre-diameter tires and wheels and most often race on full size auto-racing circuits.
A motorized bicycle is a bicycle with an attached motor or engine and transmission used either to power the vehicle unassisted, or to assist with pedalling. Since it sometimes retains both pedals and a discrete connected drive for rider-powered propulsion, the motorized bicycle is in technical terms a true bicycle, albeit a power-assisted one. Typically they are incapable of speeds above 52 km/h (32 mph); however, in recent years larger motors have been built, allowing bikes to reach speeds of upwards of 113 km/h.
A micro kart is a small, one-passenger mini go-kart. These karts typically have two-stroke engines, ranging in size from 22.5 cc to 85 cc, and putting out anywhere from 1.2 hp to over 20 hp, or an electric motor with rechargeable lithium-ion batteries.
This article gives an outline of Formula One engines, also called Formula One power units since the hybrid era starting in 2014. Since its inception in 1947, Formula One has used a variety of engine regulations. Formulae limiting engine capacity had been used in Grand Prix racing on a regular basis since after World War I. The engine formulae are divided according to era.
A quadracycle is a four-wheeled human-powered land vehicle. It is also referred to as a quadcycle, pedal car or four-wheeled bicycle amongst other terms.
The 2si 460 is a family of in-line twin-cylinder, two-stroke, single ignition, aircraft engines that were designed for ultralight aircraft.
Microstock is a form of full roll cage go cart or kart racing that originated in New Jersey invented by Bill and Bob Wagner.
KF1 was the top level of karting. It is open to drivers aged 15 and up.
An electric go-kart is a type of go-kart powered by electric motors and batteries or supercapacitors, as opposed to a traditional petrol engine.
The PRD Fireball is a two-stroke go-kart racing engine manufactured by Pro Racing Design Co, Ltd. Pro Racing Design is a Taipei, Taiwan based company, manufacturing an array of racing engines for use in professional go-kart racing worldwide. Pro Racing Design was founded by Chris Dell from Australia and it is now an Australian based manufacturer. The Fireball represents an engine targeted for multiple racing classes: International Kart Federation (IKF), World Karting Association (WKA) and Touch and Go (TAG) USA. The PRD Fireball is the cheapest TAG motor available to purchase new in the USA.
The Maserati MC20 is a two-seater, rear-mid-engine sports car produced by Italian car manufacturer Maserati.
