7 gear dual-clutch gearbox DSG.

Our aim: To achieve more agility and at the same time consume less fuel. Our solution: A seventh gear! Thanks to the innovative 7 gear configuration we have been able to design the first gear with a shorter range. That improves the start-up behaviour considerably. As the gearbox stages are close together and it is equipped with overdrive, the seventh gear with its large transmission ratio saves significantly more fuel – and therefore reduces the emission of CO2. One positive side effect is even audible – or rather inaudible – the vehicle runs even more quietly.

But how does the new 7 gear dual-clutch gearbox DSG actually work in practice? Here is an example: When the vehicle is travelling in sixth gear and accelerates further, the seventh gear is already engaged – but not yet active. When the ideal shift point has been reached the clutch for the sixth gear automatically opens. At the same time the other one closes and thereby activates the seventh gear. The result of this interplay between the two clutches: optimal driving comfort without any interruption of traction power.

Compared with conventional manual transmissions and converter transmissions the new 7 gear dual-clutch gearbox DSG is clearly at an advantage:

• It allows for direct and completely smooth gear shift operations.
• It is as driver-friendly as a full automatic transmission.
• Lively handling characteristics and dynamic driving are guaranteed: through gear shifts without traction power interruption.
• It responds positively and spontaneously, with extremely short reaction times.
• And it is economical and helps to conserve resources: With the practically loss-free operation of the dual clutch it is even possible – depending on the driving behaviour – to reduce the fuel consumption to below that of manual transmissions.
• Qualities which not only demonstrate the trailblazing nature of this transmission concept, but also something much more important: its day-to-day dependability. Never mind what driving conditions prevail, it ensures that the vehicle is driven correctly.
