Group 6 (racing)
Group 6 was the official designation applied by the FIA to two motor racing classifications, the Prototype-Sports Car category from 1966 to 1971 and the Two-Seater Racing Cars class from 1976 to 1982. Group 6 Prototype-Sports Cars (1966 to 1971) The original Group 6 was introduced for the 1966 racing season, at the same time as a new Group 4 Sports Car category. Whilst Group 4 specified that competing cars must be one of at least fifty examples built, Group 6 had no minimum production requirement. Nor did it have a maximum engine capacity limit although there were weight, dimensional and other restrictions placed on the Group 6 cars.M.L Twite, The World’s Racing Cars, 4th Edition, 1970, Page 136 The Prototypes and Sports Cars categories each had their own international championships to fight for but many of the major international endurance races such as the 24 Hours of Le Mans would count as qualifying rounds for both championships. 1968 saw a three-litre engine capacity l ...

Hewland
Hewland is a British engineering company, founded in 1957 by Mike Hewland, which specialises in racing-car gearboxes. Hewland currently employ 130 people at their Maidenhead facility and have diversified into a variety of markets being particularly successful in electric vehicle transmission supply. Hewland are currently supplying into Formula 1, Formula E, DTM, LMP, RallyCross, Prototype and GT Sportscar. History Mike Hewland ran a small engineering business at Maidenhead in the UK with the speciality in gear cutting. In 1959, Bob Gibson-Jarvie, the Chief Mechanic of UDT Laystall racing team running Cooper F2 cars, sought help from Hewland as gearbox troubles were experienced. The result of this request came out as six successful gearboxes being designed and built in 1959, and Hewland was in the gearbox business. The first transaxle product, the Hewland Mk.I of 1960, was a minor modification of the Volkswagen Beetle 4 speed transaxle used upside-down with custom made differ ...

Sports Prototypes
A sports prototype, sometimes referred to as simply a prototype, is a type of race car that is used in the highest-level categories of sports car racing. These purpose-built racing cars, unlike street-legal and production-based racing cars, are not intended for consumer purchase or production beyond that required to compete and win races. Prototype racing cars have competed in sports car racing since before World War II, but became the top echelon of sports cars in the 1960s as they began to replace homologated sports cars. Current ACO regulations allow most sports car series to use two forms of cars: grand tourers (GT), based on street cars, and prototypes, which are allowed a great amount of flexibility within set rule parameters. In historic racing, they are often called "sports racing cars". Sometimes, they are incorrectly referred to as "Le Mans cars", whether they are competing in the Le Mans race or not.

Chevron Racing Cars
Chevron Cars Ltd. is an English manufacturer of racing cars, founded by Derek Bennett in 1965. Following Bennett's death in 1978, the firm has remained active in various guises. The original company's designs and name continue to be used to build replacement parts and continuation models of earlier Chevrons. In 2000, Chevron Racing Cars Ltd., founded by Vin Malkie acquired the trade mark Chevron Racing Cars Ltd and in addition to the company's other activities has designed and built new grand tourer racing cars under the Chevron name, as well as other continuation models of earlier Chevrons. History Derek Bennett Derek Bennett was born in 1933 in Manchester; he was brought up in Prestwich. He was a largely self-taught, intuitive engineer and a talented amateur racing driver. In his early years Bennett took a keen interest in model aircraft. He took an apprenticeship in mechanical and electrical engineering before becoming a mechanic, but he soon fell in with motor racing ...

Formula One Engine
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. Operation Formula One currently uses 1.6 litre four-stroke turbocharged 90 degree V6 double-overhead camshaft (DOHC) reciprocating engines. They were introduced in 2014 and have been developed over the subsequent seasons. The power a Formula One engine produces is generated by operating at a very high rotational speed, up to 20,000 revolutions per minute (rpm). However, they are electronically limited to 15,000 as of 2021 season. This contrasts with road car engines of a similar size, which typically operate at less than 6,000 rpm. The basic configuration of a naturally aspirated Formula One engine had not been greatly modified since the 1967 Ford Cosworth DFV and the mean effective pressure had stayed at around 14 b ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom, and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission; common types of automatic transmissions are the hydraulic automatic transmission (AT), and the continuously variable transmission (CVT), whereas the automated manual transmission (AMT) and dual-clutch transmis ...
