The DSG transmission

The DSG transmission was developed by VW & Audi. This is an amazing transmission. It delivers more power to the wheels than a standard automatic transmission. That is mostly due to the fact, it's not really an automatic transmission at all. The DSG is actually more like 2 3 speed manual transmissions in one. There is no clutch on the DSG transmission it's controlled electronically. When starting from idle the transmission is in 1st and 2nd gear, however the clutch is engaged on second gear. The vehicle takes off in first gear and when it is ready to go into secondary gear the clutch is applied to the first transmission and automatically swaps to 4th gear, as the 2nd transmission is engaged. The result of this technology is a faster gear change than any human can do. According to Audi, the A3 runs 0-60 in 6.9 seconds with a 6-speed manual and 6.7 seconds with the 6-speed DSG. When down shifting the DSG transmission the transmission goes into neutral with clutch applied and matches engine speed according to road speed then engaged downward gears flawlessly. The automatic feature has a regular drive function for normal driving. As well as a sport feature which lets each gear rev out longer, important for vehicles such as the 2.0T GTi, since the turbo is more effective at higher RPMs. To shift the DSG gear box into manual feature you slide the gear selector over to the right, and either use the slap shifter feature, or the paddle shifters located on the steering wheel.



- Personal Thoughts

With a transmission like the DSG, why would any sports enthusiast still want a regular manual transmission, the DSG is faster at the track, and more convenient around town. Some people will still prefer the manual transmission to have more say to the vehicle's input but the DSG has it covered. It's very fun to drive vehicles with the DSG, flawless shifts, and a lot of fun with the paddle shifters. Great Transmission!!

Nice. I like your enthusiasm. I'm a Volkswagen/Audi fan, but I must point out that the DSG was actually developed by Borg Warner together with VW/Audi and licensed to VW/Audi.
