Just checked out the Audi web-page -- according to the technical specifications of the A8, the quattro version is *lighter* than the fwd version (3,619 vs 3,850 lbs)! How'd they do that (esp. since the difference is over 200 lbs)? -Arun -- Arun Rao Scientist Pixar 1001 W. Cutting Blvd. Pt. Richmond, CA 94804 (510)215-3526
