![]() ![]() Inside the car the driver only sees a brake and a throttle with the gear selection via the dual clutches, one controlling odd gears (one, three, five and reverse, for example) and the other one controlling even gears (two, four, and six). What is a DSG, and how does it work?Ī DSG, or dual-clutch gearbox is, in simplistic terms, a manual transmission with two clutch packs to control odd and even gears. This article explain how a DSG works and why driving a car with one isn’t like driving a normal automatic. With gear selection, up or down, happening in around 8 milliseconds most drivers will be virtually unaware of what’s going on. And, despite what your mates might tell you, most DSGs can skip gears from, say, sixth straight to fourth in auto (or D for Drive) mode or by a double-pull of the shift paddles. ![]() And because of how a DSG works there’s no loss of power or momentum during up shifts thanks to the pre-selection of the next gear in the other gear set, and its manually controlled shift is much faster than a driver shifting gear in a conventional manual.Īll DSGs allow for both manual and automatic modes. ![]() It offers a half-way between the ease of driving you get form a normal automatic transmission (because there’s only a brake and accelerator pedals) and the ‘control’ of a manual transmission just without the physical action of depressing a clutch. But, unlike that ‘normal’ automatic, a DSG effectively mates two gear sets (one with odd gears – 1-3-5 and the other with even gears – 2-4-6) and two clutches to allow for pre-selection of gears and a seamless swap between them. Like a conventional automatic transmission, a DSG uses fixed gear ratios to ensure an engine is running at its most efficient rpm (revolutions per minute) depending on the speed. This is a newer type of automatic transmission that had its birth in motorsport via Porsche, but it was Volkswagen that made DSG a household name. ANYONE WHO’S considered buying either a Volkswagen or Skoda, or even some Hyundai models will have come across the term DSG, or DCT although both refer to the same thing a dual-clutch gearbox/transmission. ![]()
