With superior traction, great balance, and capable steering, the 2008 Audi S6 is a powerhouse of a sedan.
The Audi S6 can go from 0-60 in just 5.1 seconds, says MyRide.com. The 2008 Audi S6 has "5.2-liters of displacement, direct injection, a 12.5:1 compression ratio and dual overhead cams," making it so "the 40-valve aluminum V10 boasts 435 horsepower at 6,800 rpm and 398 lb.-ft. of torque at 3,500 rpm (90 percent of the total torque is available between 2,300 and 6,200 rpm)." ForbesAutos calls the engine "glee-inducing" and cautions "lay a big toe on the accelerator and hold on, because off you go."
Autoblog points out that this Audi 2008 model has a 40/60 split front-to-back power distribution via standard quattro all-wheel drive and a six-speed automatic. However, if the surface conditions change, the split can go as far as distributing 85 percent of the power to the rear wheels or 65 percent to the front wheels. Cars.com notes, "Purists will bemoan the lack of a true manual transmission," but the selectable sport mode keeps the rpm running high and allows for steering wheel paddles to be used for shifting or a gear shifter for sequential-manual shifting. And while ForbesAutos understands the concern over a lack of manual transmission, they "found it highly enjoyable," noting this is most likely due to the fact that "no matter what kind of gear-changing device it's channeled through, 435 horsepower is going to be fun."
Fuel economy in this Audi 2008 model is a bit of a drag with 14 mpg in the city and 19 mpg on the highway, according to Edmunds.
The 2008 Audi S6 keeps a tight grip on the road because of its 265/35 performance tires, says MyRide.com, and the electronic stabilization program also makes for better handling in tricky road conditions. They call braking a "consistently worry-free endeavor" and note steering is equally "praiseworthy," except for the need of a bit more "road feel" and "responsiveness." Body roll is minimal, says ForbesAutos, and the Audi S6 car feels "unexpectedly light on its feet" when out on the open road, making for "excellent" ride quality. Even so, they call the pedal sensitivity "disconcerting, because at low speeds the gas pedal can feel like an on/off switch." They further mention how this can be a real pain in high traffic times. "The brakes are likewise quick to grab hold, which can be annoying when creeping along during rush hour," they say.
TheCarConnection.com’s editors believe the 2008 Audi S6’s hard-edged engine and sport-tuned suspension give drivers plenty to play with, despite the lack of a manual transmission. There's even a "sport" mode in the automatic that holds gears at redline, for the true racer, so you can hear that glorious, throaty, muffled roar. The transmission, steering, chassis, and brakes are appropriately upgraded for such prodigious power. The steering is perfectly weighted and responsive, the brakes powerful and sure, the ride motions beautifully damped as the big tires grip, the suspension takes a set, and your thumbs call up exactly the right gear to power through each corner, whether slow, fast, or ruggedly rough.
The 2008 Audi S6 is Hercules on wheels, with all-wheel-drive grip as a bonus.
