Gear changes – imperceptible and fast.
| The principle of overlapping gear changes in the DSG is as follows: when one gear is engaged, another gear is always preselected. If a gear change is approaching, one clutch opens within three to four hundredths of a second while the other closes. The mechatronics unit ensures that this takes place fast and accurately on a level that would not be possible manually. In this way, the change of gear is imperceptible to the driver and is achieved without any interruption of the driving power. |
The decision as to which gear should be engaged next is taken by the control unit based on the position/operation of the accelerator, engine speed and vehicle speed. If the accelerator pedal is pressed and the vehicle accelerated, the next-highest gear will be preselected before the shift point is reached. If the accelerator is not operated, however, i.e. the vehicle is in overrun, the next-lowest gear will be preselected. | |
| The advantages in detail:- The Volkswagen DSG permits smooth gear-changing along with the additional comfort of an automatic gearbox.
- The virtually loss-free dual clutch even cuts the fuel consumption of some models featuring DSG to below that of manual models depending on the style of driving.
- The Tiptronic with manual, sequential gear selection offers sporty driving enjoyment due to direct gear-shifting.
