R.T. Quaife Engineering, Ltd. is a British manufacturer of automotive drivetrain products. It designs and manufactures motorsport and performance orientated gearboxes, gearkits, differentials, steering racks and axle kits, along with many other associated drivetrain products.
The company was founded in 1965, by Rod Quaife and is now run and owned by Sharon Quaife-Hobbs, Sharon's son Adrian Quaife-Hobbs is the owner of Pro-Sim and is a professional racing driver.
The early days at Quaife were spent manufacturing performance motorcycle gearkits, most notably close ratio 5-speed units for Triumph, BSA and Norton. Quaife also took on subcontracted work from AMC; the makers of Matchless and AJS motorcycles. Quaife gearkits were used to achieve victories in the Daytona Speedway and Isle of Man TT.
Based near Sevenoaks, Kent they have two sites, one in Sevenoaks and the other, their OEM production facility, in Gillingham.
Quaife's signature product is its line of automatic torque biasing differentials, a form of limited slip differential that employ helical gears rather than clutch mechanisms that are controlled mechanically. These differentials are usually available as aftermarket items, but for some models are specified by automobile manufacturers as OEM equipment. Quaife's ATB differential is now available in over 300 different applications, covering everything from Alfa Romeo to Volvo. Originally developed in the 1980s, the ATB differential appeals to many performance and racing car enthusiasts for its mix of traction-enhancing abilities, reliability, smooth operation and its 'fit and forget' installation. Within many markets, the Quaife ATB differential also comes with a lifetime warranty; applicable to both road and race environments.
Aside from manufacturing precision engineered differentials, Quaife also produces highly sought after sequential gearboxes. The Quaife QBE60G and QBE69G heavy duty 6-speed sequential gearboxes are offered with several bell housings to fit a number of popular racing applications. Other sequential transmissions cater for applications including the Ford GT40, Land Rover V8, Mitsubishi EVO 4–9, Nissan Skyline GTR R32-R34 and Porsche 996 and 997. Quaife also offers many transmissions in synchromesh and dog engagement formats.
Quaife's range of motorsport gearkits replace the standard internals of many popular transmissions found in both classic and contemporary vehicles. Initially the company focused on classic British cars as well as those manufactured by Ford Motor Company. Over recent years, the company has expanded its gearkit offering by catering for many front-wheel drive vehicles including Honda K-Series, Volkswagen 02M/02Q and a number of Ford applications.
Elsewhere, Quaife driveline components can be found in a wide range of vehicles, including those from Radical Sportscars, Caterham, Ginetta, Morgan Motor Company and Donkervoort. Quaife sequential transmissions help to power Mini JCW Challenge race cars, while the Ligier JS P4 manufactured by Onroak Automotive uses Quaife sequential technology.
Quaife has also briefly built complete road cars, with the R4 GTS in 1999 which also competed in the British GT Championship. [1] The company has also produced a roadster which was known as the R40.
Quaife continues to manufacture and supply ATB differentials for Ford Motor company for the Fiesta ST, Puma ST and Transit Custom.
A differential is a gear train with three shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average.
Caterham Cars is a British manufacturer of specialist lightweight sports cars established in Caterham, Surrey, with their headquarters in Crawley, Sussex. Their current model, the Caterham 7, originally launched in 1973, is a direct evolution of the Series 3 Lotus Seven designed by Colin Chapman. In the 1990s the company made the Caterham 21, a two-seater soft top alternative to the MGF and Lotus Elise,. A track-only car, the SP/300.R, a joint project with Lola was released for customer testing in 2010 and was scheduled for release in 2013. On 27 April 2011, Team Lotus owner Tony Fernandes announced that he had purchased Caterham. On 2 April 2021, news was leaked that Caterham Cars was acquired outright on 31 March 2021 by VT Holdings, Japanese importer for the Caterham Seven since 2009. As well as being a Caterham importer, VT also imports Lotus cars and Royal Enfield motorcycles into Japan.
Four-wheel drive, also called 4x4 or 4WD, refers to a two-axled vehicle drivetrain capable of providing torque to all of its wheels simultaneously. It may be full-time or on-demand, and is typically linked via a transfer case providing an additional output drive shaft and, in many instances, additional gear ranges.
The Mitsubishi Lancer Evolution, commonly referred to as 'Evo', is a sports sedan based on the Lancer that was manufactured by Japanese manufacturer Mitsubishi Motors from 1992 until 2016. There have been ten official versions to date, and the designation of each model is most commonly a Roman numeral. All use two litre turbocharged inline four-cylinder engines and all-wheel drive systems.
A transmission is a machine in a power transmission system, which provides controlled application of power. Often the term 5-speed transmission refers simply to the gearbox, that uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device.
The Dodge Challenger is the name of three different generations of automobiles produced by American automobile manufacturer Dodge. However, the first use of the Challenger name by Dodge was in 1959 for marketing a "value version" of the full-sized Coronet Silver Challenger.
A limited-slip differential (LSD) is a type of differential that allows its two output shafts to rotate at different speeds but limits the maximum difference between the two shafts.
Semi-automatic transmission denotes a multi-speed motor vehicle transmission where part of its operation is automated, but the driver's input is still required to launch the vehicle from a standstill and to manually change gears. Most semi-automatic transmissions used in cars and motorcycles are based on conventional manual transmissions or a sequential manual transmission, but use an automatic clutch system. However, some semi-automatic transmissions have also been based on standard hydraulic automatic transmissions, with, or incorporating a fluid coupling or torque converter, and a planetary gearset.
The Ford MTX-75, is a 5-speed transmission developed by Ford Motor Company for its larger-engined front wheel drive models. "75" refers to the distance in millimeters between the main and lay shafts.
Drifting is a driving technique where the driver intentionally oversteers, with loss of traction, while maintaining control and driving the car through the entirety of a corner. The technique causes the rear slip angle to exceed the front slip angle to such an extent that often the front wheels are pointing in the opposite direction to the turn. Drifting is traditionally done by clutch kicking, then intentionally oversteering and countersteering. This sense of drift is not to be confused with the four wheel drift, a classic cornering technique established in Grand Prix and sports car racing.
Torsen Torque-Sensing is a type of limited-slip differential used in automobiles.
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.
The Tremec TR-6060 six-speed manual transmission features six forward speeds and one reverse speed. It is derived from the Tremec T-56 6-speed manual transmission. As usual, the forward helical cut gears are synchronized however, the reverse gear operates through a fully synchronized constant-mesh system. The TR-6060 contains removable wear pads on the shift forks, and uses aluminum alloys for the main case, extension housing, and clutch housing. It is manufactured by TREMEC and is rated for 600 lb⋅ft (810 N⋅m) of torque.
