![]() The less time spent off the power changing gear during acceleration the faster the vehicle can accelerate - and by reducing the time spent off the power during gear changes in general, the better fuel economy will be as engine power isn’t wasted. The purpose behind a DCT is to reduce the gap between gear shifts to a minimum, with the benefits being improved performance and fuel efficiency. It wasn’t until 2003 that a production road car featured a DCT, in Volkswagen’s Mk4 Golf R32. The electronics needed for the computerised control module had not yet reached the miniaturisation levels of modern times and so were quite sizeable and took up valuable engine bay space. Space was also a considerable restriction. The Porsche 956 released in 1983 received the distinction of being the first to feature one, and their complexity and expense kept them in the realm of motor racing and high-end super cars for the most part. Its realisation had to wait until the 80’s, and it was Porsche who eventually became the first major adopter having worked on their own version since the 60’s. Like so many ‘new’ developments for automobiles, the double clutch transmission is an idea that had been around for a significant amount of time before finally being put to use, having been experimented with pre-World War two. ORIGINSĪlso referred to as a Direct Shift Gearbox (DSG), most car manufacturers have their own version or versions, but use them selectively across their ranges of vehicles – with the Volkswagen group the most invested in their implementation. Sitting in the middle ground between an automatic and a manual transmission, the simplest way of describing their operation, is that they’re an automatically operated manual transmission – achieved by using two clutches.ĭoing away with the torque converter of a normal automatic transmission, they utilise the traditional gearing methods of a manual - but then split that gearing across two output shafts to allow power flow to shift between them incredibly quickly. 4 Benefits of Owning the 2023 Volkswagen ID.Despite what is undoubtably very clever and complex engineering, the Double (or Dual) Clutch Transmission (DCT), has a mixed reputation with drivers and has not achieved the level of ubiquity many thought it would.Top 3 Family-Friendly Volkswagen SUVs for 2023 in Brookfield, WI.Explore the Features of Keyless Access in Your Volkswagen.4 Advantages of Buying a CPO Volkswagen in Brookfield, WI.Also, check out our new VW incentives and manager’s specials to get the lowest price on a new VW.

For a dual-clutch transmission, shifting out of a gear and into another is the same action, making for a quicker and smoother shift. While a car can do this pretty quickly, it still takes time and wears down the transmission. When a regular automatic transmission shifts from one gear to the next, it first has to shift out of the gear it’s currently in, find the next gear, and then shift into it. You may think that your regular automatic does this it does not. The advantage of a dual-clutch transmission is that it shifts directly from one gear into another. ![]() You put the car “Drive” and it does the rest. From a driver input standpoint, a dual-clutch transmission and a standard automatic work exactly the same. So, one clutch handles 1 st, 3 rd, 5 th, etc., gears while the other handles 2 nd, 4 th, 6 th, etc., gears. Each part of the “dual-clutch” aspect handles alternating gears. What is a Dual-clutch Automatic Transmission?Ī dual-clutch automatic transmission, like the seven-speed Volkswagen DSG, uses alternating gears to shift directly into the next gear from the current one.
