以下有关DSG的评论摘自The Dog and Lemon Guide:
DSG (also called the S-Tronic) transmissions are the pits. They’re essentially a racing system that has been adapted to suburban use. That’s a bit like playing football using the rules for baseball. DSG transmissions were supposed to offer the convenience of an automatic with the performance of a manual. Alas, reality has a nasty habit of spoiling the fun.
Leaving aside the frequent reliability issues (and the staggering repair costs), DSG transmissions are often horrible to live with on a daily basis. For example, take a typical motoring situation: you’re in a slow moving line of traffic, waiting to get into a carpark. Whereas a conventional automatic is happy to smoothly creep along, adjusting itself to your chosen speed, the DSG operates in a series of small jerks. This is bad enough when you’re moving slowly, worse when you’re coming to a halt and worse still when you’re trying to park in a tight space. Instead of easing the car into the available space, the DSG hesitates then jumps, just enough to get you into trouble.
Even away from the crowded cities, the DSG frequently loses the plot. Part of the attraction of these gearboxes is extremely quick gearchanges, selectable using flappy paddles mounted behind the steering wheel. In order to change gear quickly, these gearboxes essentially guess which gear the driver is going to need next, and have it ready to change when he or she blips the flappy paddle. This system works fine on a racetrack, but in the real world, you can be halfway through a casual overtaking procedure when a truck suddenly looms into view, heading straight towards you. You floor the accelerator to get away from this threat and … and….and...the gearbox has to stop and think, then select a low gear and surge forward. Eventually.
The problem with any selectable system is that it can’t possibly predict all the shifts you’re going to need, so it changes gear for you with a ‘mother knows best’ hamfistedness that often destroys the driving experience, which, after all, is the primary reason you’d want a gearbox that changes gear very quickly. The whole system is daft in the extreme.
This is not merely our opinion: Volkswagen in America was recently forced to recall all 2007-2009 Volkswagens and Audis fitted with DSG. The models covered were the Volkswagen R32, Jetta, Jetta SportWagen (UK Golf estate), GTi, Eos, as well as Audi A3 and TT. VW America was also forced to extend the warranty on these transmissions to ten years to allay reliability concerns. This was an American recall and was not extended to many other countries. Nor was the warranty. |
