Bought a copy of Performance Car magazine which tested a '98 A6 Quattro vs. a '98 A6. The results were very interesting.
On 0-100-0: "The Quattro made its traction off the line count, leaping to 30 mph in 2.1 secs, passing 60mph in a rapid 6.9 sec but then fading slightly to hit the magic 100 in 19.6 secs...but the front-drive SE was marginally quicker to 100 at 19.3 secs. despite trailing the quattro at 30 and 60 (2.7/7.2). Interestingly, the SE had traction control and we recorded our best times with it switched in..."
On Lateral G's: "In theory, there should be no difference...this is a steady-state test using constant throttle opening and both cars have the same size tires, so the quattro doesn't get a chance to show it can redistribute the engine's torque. The reason the quattro is a fraction quicker around the circle is more likely its lower, stiffer suspension."
On wet handling: "You'd expect the quattro to leave the fwd choking in its spray here...the times both drivers recorded for the A6's were within tenths: Barker lapped the quattro in 38.7 secs and the fwd in 39.0 secs, while Strong's times were even closer at 41.0 secs for the quattro and 41.1 secs for the fwd. Barker's best times for the fwd were set with traction control off. It looked less tidy, with plenty of wheelspin, but helped maintain revs out of the tight turns, as on the dry handling circuit. Strong commented that the fwd felt more adjustable, with a helpful degree of tail swing when late braking into the same turns."
Wet lateral g: "Subjectively, the quattro had a definite edge; it seemed to have better bite and more balance, holding its line with less steering lock than the fwd. That said, they both looked impressively rapid around the glassy circle and their lateral g ratings were very close."
0-30 mph wet: "Even with a quarter of an inch of water under its tires the quattro punched off the line almost as well as most fwd cars can manage in the dry. The fwd recorded its best acceleration times with traction control on..."
0-30 mph ice: "This was the only test that proved categorically the benefits of four-wheel drive. "...and the fwd struggled. The revs flared and died as the traction control system went on overtime, and slowly and
agonizingly the front-drive A6 picked up speed. By contrast, the quattro dragged itself to 30 mph with ease. There were some unusual sensations as the drivetrain juggled the torque, favoring the front and rear wheels in turn, but there was no denying it was an impressive performance."
