Any good sites with info on the Quattro system?
With winter coming, I'd like to learn more about the drive system and how best to use the electronics in snow, ice, etc.
I've had 4 wheel drive trucks before with open and locking diffs. I just like to learn how the quattro is the same/different.
Thanks,
John

Wow, spectacular article (more)>>>
That was exactly what I was looking for, thank you.
At the end of the article, it mentioned some of the Quattros using a haldex system. Do the C6 A6's still use the Torsen system?

The C6 retains Torsen based AWD. Haldex is used in platforms with transversely
mounted engines. Cars like the TT, R32, etc. The new Passat uses Haldex too, but the last one used Torsen. That's because the new Passat is based on a longer and wider version of the MK V platform (basis for Golfs, Jettas, and my A3 among others).
Most longitudinal engines Audis use the T-1 Torsen, however, I think the RS4, next S6, and S8, all use the T-3.
The latest Haldex can be equipped with something called, "Pre X". This allows for quicker responses than before, and in some cases, acts with the electronic throttle and ESP unit to pro-actively shunt power to wheels before slip even occurs.<ul><li><a href="http://www.torsen.com/products/products.htm">Torsen info</a></li></ul>

The 2006 S4 six-speed also has Torsen T-3. If the C6 RS 6 is ever built, it too will have Torsen T3. Currently, all Audis with longitudinally mounted engines have Torsen T-2, not Torsen T1. Torsen T1 was last used in the B4 80/90 Series/S4, C4 100/200 Series/A6/S6 and D1 V8. As for the engine in the C6 RS 6 (again, if it is ever built), I am betting on a high revving (9,000-9,500 RPM redline) normally aspirated hybrid 5.5L FSI V10 with a total of 600 hp and 516 lbs/ft of torque (50 hp and 103 lbs/ft of torque from the electric motor; 550 hp and 413 lbs/ft of torque from the FSI V10 itself). A hybrid FSI V10 would be far more fuel efficient, far cleaner, far more space efficient, far more reliable, far less costly and much lighterweight than a twin turbo FSI V10 would be. The overall performance of the C6 RS 6 with a hybrid FSI V10 would also be much better than it would be with a twin turbo FSI V10.

Re: Well, you can dream.
Hybrid technology from Audi is not unrealistic. In fact, the Q7 4.2 Hybrid is supposed to go into production in late 2007 for 2008. The 4.2L FSI V8 in the Q7 4.2 Hybrid is supposed to produce 370 hp and 325 lbs/ft of torque while the rear mounted electric motor is supposed to produce 50 hp and 147 lbs/ft of torque for a total of 420 hp and 472 lbs/ft of torque. And with Audi's trend of reserving forced induction for their diesel (turbocharged only) and FSI four-banger (available in normally aspirated form and turbocharged form) engines, the likelihood of the C6 RS 6 having the hybrid technology I described in my last message is very high even though it is not definite or confirmed.
