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 2009 Audi 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.
