An automatic transmission is a multi-speed transmission used in motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. Vehicles with internal combustion engines, unlike electric vehicles, require the engine to operate in a narrow range of rates of rotation, requiring a gearbox, operated manually or automatically, to drive the wheels over a wide range of speeds.
Overdrive is the operation of an automobile cruising at sustained speed with reduced engine speed (rpm), leading to better fuel consumption, lower noise, and lower wear. The term is ambiguous. The most fundamental meaning is that of an overall gear ratio between engine and wheels, such that the car is over-geared, and cannot reach its potential top speed, i.e. the car could travel faster if it were in a lower gear, with the engine turning at higher RPM.
A transmission is a mechanical device which uses a gear set—two or more gears working together—to change the speed or direction of rotation in a machine. Many transmissions have multiple gear ratios, but there are also transmissions that use a single fixed-gear ratio.
A manual transmission (MT), also known as manual gearbox, standard transmission, or stick shift, 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.
A transfer case is an intermediate gearbox that transfers power from the transmission of a motor vehicle to the driven axles of four-wheel-drive, all-wheel-drive, and other multi-axled on- and off-road machines. A part of the vehicle's drivetrain, it employs drive shafts to mechanically deliver motive power. The transfer case also synchronizes the difference between the rotation of the front and rear wheels, and may contain one or more sets of low range gears for off-road use.
A semi-automatic transmission is a multiple-speed 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. Semi-automatic transmissions were almost exclusively used in motorcycles and are based on conventional manual transmissions or sequential manual transmissions, but use an automatic clutch system. But some semi-automatic transmissions have also been based on standard hydraulic automatic transmissions with torque converters and planetary gearsets.
A direct-shift gearbox is an electronically controlled, dual-clutch, multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout, with automated clutch operation, and with fully-automatic or semi-manual gear selection. The first dual-clutch transmissions were derived from Porsche in-house development for the Porsche 962 in the 1980s.
The Jaguar S-Type is a saloon car produced by Jaguar Cars in the United Kingdom from 1963 to 1968. Announced 30 September 1963 it was a technically more sophisticated development of the Mark 2, offering buyers a more luxurious alternative without the size and expense of the Mark X. The S-Type sold alongside the Mark 2, as well as the Jaguar 420 following its release in 1966. A retro-styled vehicle with the same name was also produced, based on the design of the original S-Type vehicles.
Formula One Grand Prix is a racing simulator released in 1991 by MicroProse for the Amiga, Atari ST and PC created by game designer Geoff Crammond. It is often referred to as Grand Prix 1, MicroProse Grand Prix, or just F1GP. Although the game itself was not affiliated officially with the FIA or any Formula One drivers, team liveries and driver helmets were accurate to represent the 1991 season, but the names were fictional. The game is a simulation of Formula One racing at the time and was noted for its 3D graphics, remarkably high framerate and attention to detail, in particular the player's ability to edit the teams and drivers and set up their car to their own personal specifications. The game was ranked the 27th best game of all time by Amiga Power. Grand Prix's success spawned three sequels, called Grand Prix 2, Grand Prix 3 and Grand Prix 4.
The Armstrong Siddeley Sapphire is a large automobile which was produced by the British company, Armstrong Siddeley Motors Limited, from 1952 to 1960.
A gear stick, gear lever, gearshift or shifter, more formally known as a transmission lever, is a metal lever attached to the transmission of an automobile. The term gear stick mostly refers to the shift lever of a manual transmission, while in an automatic transmission, a similar lever is known as a gear selector. A gear stick will normally be used to change gear whilst depressing the clutch pedal with the left foot to disengage the engine from the drivetrain and wheels. Automatic transmission vehicles, including hydraulic automatic transmissions, automated manual and older semi-automatic transmissions, like VW Autostick, and those with continuously variable transmissions, do not require a physical clutch pedal.
Jaguar XJ220 is a pseudo-3D racing game released by Core Design for the Amiga in 1992 and Mega-CD in 1993. The car featured is the eponymous Jaguar.
Top Gear 3000, later released in Japan as The Planet's Champ: TG3000, is a racing video game developed by Gremlin Interactive and published by Kemco for the Super Nintendo Entertainment System. It is the third game in the original Top Gear trilogy, and the last in the series to be developed by Gremlin. 3000 heavily resembles the previous Top Gear 2, but is set in the distant future.
Top Gear 2 is a racer video game developed and published by Gremlin Interactive. A direct sequel to the 1992 game Top Gear, it was first released by Kemco for the SNES in North America on August 8, 1993, and then the Super Famicom in Japan on December 22. It was later ported to the Amiga on May 24, 1994 by Gremlin Interactive, and to the Sega Genesis on June 2 by Vic Tokai. While more realistic than its predecessor, Top Gear 2 maintained the arcade-style gameplay the series is known for.
A sequential manual transmission, also known as a sequential gearbox, or a sequential transmission, is a type of non-synchronous manual transmission used mostly for motorcycles and racing cars. It produces faster shift times than traditional synchronized manual transmissions, and restricts the driver to selecting either the next or previous gear, in a successive order.
5G-Tronic is Mercedes-Benz's trademark name for its five-speed automatic transmission, starting off with the W5A 580 and W5A 330 as core models.
Selespeed is the name of an automated manual transmission used in Alfa Romeo cars, developed by Italian company Magneti Marelli and made by Graziano Trasmissioni.
Subaru launched the third generation Japanese and world-market Legacy in June 1998, while the North American model was introduced in May 1999 for the 2000 model year. In all markets except for the United States, production lasted through 2002, with a limited production Blitzen model sold mid-cycle under the 2003 model year in Japan. Production in the United States lasted through 2004.
The Jaguar XJ (X300) is a full-size luxury saloon car manufactured by Jaguar Cars between 1994 and 1997. It was the first Jaguar XJ produced entirely under Ford Motor Company ownership, and can be considered an evolution of the outgoing XJ40 generation. Like all previous XJ generations, it features the Jaguar independent rear suspension arrangement. The design of the X300 placed emphasis on improved build quality, improved reliability, and a return to traditional Jaguar styling elements.
Powerband is a Formula 1-style racing game for the Acorn Archimedes published in 1990. It was written by Gordon J. Key and published by The Fourth Dimension. The game was released on a single 3.5" floppy disk.
