The seven-speed dual clutch transmission from Volkswagen

Abstract

Volkswagen is making two world premieres with the new seven-speed dual clutch DSG transmission. It is both the first seven-speed transmission for front transverse mounting and the first dual clutch transmission with a ‘dry’ dual clutch. The transmission is designed for a maximum torque of 250 Nm and use for vehicles in the compact class as well as, also a world premiere, for vehicles in the small class. As a build feature, the dry dual clutch has considerable benefits for the entire transmission concept. Compared to Volkswagen’s current six-speed dual clutch transmission, it comes with an even higher efficiency rating and therefore makes a significant contribution to reducing fuel consumption and emissions levels in the design of new vehicles.
