Group 5 (racing)
Group 5 was an FIA motor racing classification which was applied to four distinct categories during the years 1966 to 1982. Initially Group 5 regulations defined a Special Touring Car category and from 1970 to 1971 the classification was applied to limited production Sports Cars restricted to 5 litre engine capacity. The Group 5 Sports Car category was redefined in 1972 to exclude the minimum production requirement and limit engine capacity to 3 litres. From 1976 to 1982 Group 5 was for Special Production Cars, a liberal Silhouette racing car, silhouette formula based on homologated production vehicles. 1st Generation Group 5 – "Special Touring Cars" (1966 to 1969) In 1966 the FIA introduced a number of new racing categories including one for highly modified touring cars, officially known as Group 5 Special Touring Cars. The regulations permitted vehicle modifications beyond those allowed in the concurrent Group 1 and Group 2 Touring Car categories.M.L Twite, The World's Racing Ca ...

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. At the beginning of 2021, Hewland was acquired by Indian Hero Motors Company. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sports Prototypes
A sports prototype, sometimes referred to simply as a prototype, is a type of race car that is used in high-level categories of sports car racing. They are purpose-built auto-sports race cars, as opposed to production-car based or street-legal, low-volume homologation specials – thus entirely not intended for consumer purchase, or production beyond the fabrication of the (nearly) unique cars entered into races and in race-car competition classes or "formulas", with sufficiently open regulations to allow for vehicles of unique design to partake. 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 cars)'', which are strictly based on production street cars, and ''sports prototypes'', which are allowed a great amount of flexibility within set ru ...

Formula One Engine
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 Formula One regulations, 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 #Engine regulation progression by era, era. Characteristics Formula One currently uses 1.6 litre four-stroke turbocharged 90 degree V6 engine, V6 overhead camshaft engine#Double overhead camshaft, double-overhead camshaft (DOHC) reciprocating engines. They were introduced in 2014 and have been developed over the subsequent seasons. Mostly from the 2023 season, specifications on Formula One engines, including the software used to control them and the maximum per-engine price to F1 teams of €15,000,000, have been frozen until the end of 2025, when the completely new 2026 spec will c ...

Naturally-aspirated
A naturally aspirated engine, also known as a normally aspirated engine, and abbreviated to N/A or NA, is an internal combustion engine in which air intake depends solely on atmospheric pressure and does not have forced induction through a turbocharger or a supercharger. Description In a naturally aspirated engine, air for combustion ( Diesel cycle in a diesel engine or specific types of Otto cycle in petrol engines, namely petrol direct injection) or an air/fuel mixture (traditional Otto cycle petrol engines), is drawn into the engine's cylinders by atmospheric pressure acting against a partial vacuum that occurs as the piston travels downwards toward bottom dead centre during the intake stroke. Owing to innate restriction in the engine's inlet tract, which includes the intake manifold, a small pressure drop occurs as air is drawn in, resulting in a volumetric efficiency of less than 100 percent—and a less than complete air charge in the cylinder. The density of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canadian English, Canada, British English, the United Kingdom and American English, the United States), or stick shift (in the United States), is a multi-speed motor vehicle Transmission (mechanical device), 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 Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic ...
