A sequential manual transmission , also known as a sequential gearbox or sequential transmission , is a type of non-synchronous manual transmission used mostly in 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.

36-532: A 6.0 L mid-mounted Chevrolet fuel injected V8 engine . At the same time as the launch of the car, Klaas Zwart, a Dutch racing driver expressed interest in the car and ended up buying the entire company along with the design rights of the car. The new owner of the company chose to enter the FGT in racing, the race car featured a Ford Modular V8 engine and was entered into the British GT Championship . With
54-433: A conventional manual transmission. On a sequential manual transmission, the shift lever operates a ratchet mechanism that converts the fore-and-aft motion of the shift lever into rotation of a Gear shift drum or selector drum (sometimes called a barrel) which has three or four tracks machined around its circumference. Selector forks are guided by the tracks, either directly or via selector rods. The tracks deviate around

90-450: A layout of 1 - N - 2 - 3 - 4 - 5 - 6 (for a typical 6-speed gearbox, said as "one down, five up"). However, most modern motor scooters do not use a sequential manual transmission; instead using either a hydraulic automatic transmission , or a belt-driven or chain-driven continuously variable transmission . Underbones , however, often use a semi-automatic transmission with an automatic centrifugal clutch , but will still retain
108-509: A manual shift lever was used in the 1990 Peugeot 905 Group C sports car , followed by the Ferrari 333 SP LMP racecar and CART Champ Cars / Indycars in 1994 and 1996, and then the McLaren F1 GTR , Mercedes-Benz CLK GTR , Porsche 911 GT1 , and Panoz Esperante GTR-1 GT1 racecars in 1996 and 1997. This was closely followed by WRC Rally cars in 1997, 1998, and 1999, and also
126-696: A partial season in 1997 with only a best finish of fourth at Donington Park . Following the 1997 season, Ascari built 17 production versions of the FGT dubbed the Ecosse. The Ecosse was unveiled by Ascari at the 1999 Earls Court Motor Show. The Ecosse was given a BMW V8 engine in place of the Chevrolet and Ford units used in the FGT, although the engine was further tuned by Hartge . The 4.4 L engine produces around 300 hp (304 PS; 224 kW), while later larger 4.7 L units produced around 400 hp (406 PS; 298 kW). The last three cars were fitted with
144-514: Is different from Wikidata All article disambiguation pages All disambiguation pages Ascari FGT The Ascari Ecosse is a mid-engined sports car produced by Ascari Cars from 1998 to 1999. It was the first production car released by the company and is essentially the production version of the Ascari FGT concept race car. In 1995 Ascari introduced the FGT at various European motor shows, designed by Lee Noble . It featured
162-489: The Hartge 5.0 litre V8 engine based on the 4.4 L BMW unit. The new engine produced around 420 hp (426 PS; 313 kW) and 520 N⋅m (384 lb⋅ft) of torque. The last car was built at Blandford in 2000 with a sequential manual transmission and is still in possession of Ascari. The spaceframe chassis and wishbone suspension carry a lightweight fibreglass body, weighing 1,250 kg (2,756 lb). The Ecosse, with
180-656: The Porsche LMP1-98 , Nissan R390 GT1 , Toyota GT-One , and the BMW V12 LM ' and LMR Le Mans Prototype racecars in 1998 and 1999. Touring cars have also used sequential manual gearboxes; starting with the European DTM series in 2000, which used it for 12 seasons, until a switch to a paddle-shift system in 2012. The Australian V8 Supercars series started using sequential manual gearboxes in 2008, after switching from an H-pattern manual gearbox . NASCAR introduced
198-468: The 1958 Lotus 12 , and is technically the first proper "sequential" gearbox used in a racecar. Most racing cars also use a sequential transmission now (via a sequential shift lever, with a mechanical linkage, or electronic paddle-shifters), rather than the old H-pattern stick shift , beginning with the paddle-shifted Williams FW14 Formula One car in 1991, which used a sequential drum-rotation mechanism. The first modern sequential manual gearbox with

#1732902024709216-434: The circumference and as the drum rotates, the selector forks are moved to select the required gear. When upshifting or downshifting a sequential manual transmission, there is no need to operate the clutch, which is only required when the vehicle starts. Since the engagement ring (or "dog ring") pushed by the shift fork and moves quick, and the engagement ring begins to transmit power synchronously while it comes into contact,
234-521: The conventional foot-operated gearshift lever, such as the Honda Super Cub . The first proper sequential manual gearbox used in a racecar was with the Porsche Type 360 Cisitalia in 1946, followed by the infamously unreliable Queerbox design, pioneered by Richard Ansdale and Harry Mundy , which was used in various Lotus Grand Prix racecars during the late-1950s and early-1960s, beginning with
252-491: The larger 4.7 litre engine, can accelerate from 0–60 mph (0–97 km/h) in 4.1 seconds, while top speed is measured to be 200 mph (322 km/h). Only 17 were produced. The Ecosse was replaced by the Ascari KZ1 in 2003. Sequential manual transmission A sequential manual transmission is unsynchronized , and allows the driver to select either the next gear (e.g. shifting from first gear to second gear) or
270-404: The previous gear (e.g., shifting from third gear to second gear), operated either via electronic paddle-shifters mounted behind the steering wheel or with a sequential shifter. This restriction avoids accidentally selecting the wrong gear; however, it also prevents the driver from deliberately "skipping" gears. The use of dog clutches (rather than synchromesh ) results in faster shift speeds than
288-399: The previous or next gear through the use of buttons or a lever (usually near the gear shifter or steering wheel); however, the mechanicals of the transmission are unrelated to a true sequential manual transmission. Most motorcycles use a sequential manual transmission. The rider controls the gear shifter with their foot, allowing their hands to remain on the handlebars, and gear selection uses
306-403: The sequential manual transmission has the shortest shift speed, and the shift time is usually 5 milliseconds or less, so now used in all Formula 1 cars. A sequential manual transmission is not to be confused with a "sequential" shifting function sometimes fitted to hydraulic automatic transmission , marketed with terms such as "Tiptronic" or "SportShift". This function allows the driver to select
324-421: The sole car produced meeting the homologation requirements, Zwart won an event at Silverstone Circuit in the car's debut season of 1995. The car also attempted to qualify for the 24 Hours of Le Mans , but was not fast enough to pass pre-qualifying. The car continued to maintain pace with newcomers to British GT Championship in 1996, before Zwart partnered with William Hewland, owner of Hewland engineering, for
