Dual-clutch transmission, also known as direct-shift gearbox (DSG), represents a modern evolution of the SEAT transmission assembly. The fully-automatic, 6-speed gearbox is characterised by its ability to shift gear without interrupting traction. As a result, the gear change is very smooth and almost imperceptible to you and your passengers.
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). During a gear shift, the next gear is preselected but not yet engaged. Within three to four hundredths of a second, one clutch opens while the other closes. In this way, the gear shifts are performed imperceptibly for the driver and without any interruption in traction.
Depending on driving style, intelligent control electronics enable fuel savings of up to 10% compared to a 6-speed manual transmission.
The revolutionary SEAT 7-speed dual-clutch transmission technology is also available for smaller engines that develop torque up to 250 Newton metres. 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. The dry clutch has improved efficiency, resulting in reduced fuel consumption and emissions and even more comfort and driving pleasure.
The new DSG has received further development as well. Some components were removed, and the weight was reduced.
