7 gear dual-clutch gearbox DSG.

About 400 parts. And only 70 kg. But what makes the design of the new 7 gear dual-clutch gearbox DSG so exceptional is its ‘dry’, hydraulically controlled dual-clutch. Apart from a range of different constructional advantages, this allows a considerable reduction in the amount of lubricant needed. For only the actual gearing and the bearings still require lubricating oil, and none is needed for cooling the clutch. The result: a significantly higher efficiency rating for the gearbox and therefore lower fuel consumption.

The combination of mechatronics, intelligent electro-hydraulic gearbox control, a double-clutch, two drive shafts and three gear shafts means that the next highest transmission stage remains permanently ‘on hold’, simply waiting to be called on. And that takes place in the blink of an eye. Clutch 1 serves the odd numbered gears, whilst clutch 2 serves the even gears and the reverse gear. The effect is immediately apparent in the dynamic driving characteristics: There is no longer any loss of traction power during gear shifts.
