Compared to the harder-edged BMW M5 and the neck-snapping Mercedes-Benz E63, the
Audi S6 almost feels laid-back at times. Not for a lack of horsepower or agility,...
... mind you, but because of the sheer effortlessness with which it goes about the business of being fast. The resulting confidence makes the S6 a particularly satisfying partner on public roads. The steering and brake systems are tuned appropriately, and you can feel the quattro all-wheel drive system making its contribution to balanced handling. Highway ride comfort takes a slight degradation from the suspension's sport tuning, but even for a long coast-to-coast excursion the S6 would be among our top choices.
