![]() Some components were removed, and the weight was reduced. The new DSG has received further development as well. Thats why youll notice all the performance front engine cars like the Audi RS and BMW M going with the ZF 8HP while front engine transverse or mid/rear engine cars like the TT RS,RS3, GTI, Porsche will use DCTs. The dry clutch has improved efficiency, resulting in reduced fuel consumption and emissions and even more comfort and driving pleasure. A large reason rear/mid-engine cars stick with DCT is because the ZF 8HP is too long. The essential difference with the 6-speed dual-clutch transmission is a new dual clutch which is no longer in an oil bath and runs dry. A direct-shift gearbox ( DSG, German: Direktschaltgetriebe 1) 2 3 is an electronically-controlled, dual-clutch, 2 multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout (depending on engine/drive configuration), with automated clutch operation, and with fully-automatic 2 or semi-manual gear selection. The revolutionary SEAT 7-speed dual-clutch transmission technology is also available for smaller engines that develop torque up to 250 Newton metres. In this way, the gear shifts are performed imperceptibly for the driver and without any interruption in traction.ĭepending on driving style, intelligent control electronics enable fuel savings of up to 10% compared to a 6-speed manual transmission. That said, Continuously Variable Transmission can be less responsive than DCT and may not be suitable for high. It offers a seamless driving experience and is more fuel-efficient than conventional transmissions. Within three to four hundredths of a second, one clutch opens while the other closes. CVT is also an advanced version of an automatic gearbox that uses a belt and a pulley system to vary the gear ratio continuously. During a gear shift, the next gear is preselected but not yet engaged. Have been a follower/admirer of this forum since 2014 when I bought my first car. ![]() ![]() BHPian abhinav1817 recently shared this with other enthusiasts. And this is without considering the maintenance cost of DCT against IVT over the years. (DSG) or Dual-clutch Transmission (DCT) This is a quite rare solution due to. There is a difference of nearly 3 L OTR between both DCT and IVT. The direct-shift gearbox has two wet clutches which use two drive shafts to operate respectively the 1st, 3rd, 5th and reverse gears (clutch 1) or the 2nd, 4th and 6th gears (clutch 2). Transmission (AMT) This is a niche solution, more common on sport cars. As a result, the gear change is very smooth and almost imperceptible to you and your passengers. The fully-automatic, 6-speed gearbox is characterised by its ability to shift gear without interrupting traction. Dual-clutch transmission, also known as direct-shift gearbox (DSG), represents a modern evolution of the SEAT transmission assembly.
