Engine: 4.0L twin-turbocharged V8
Torque: 550 Nm
0–100 km/h: ~4.4 s
The C7 Audi S6 was a subtle powerhouse, hiding serious firepower beneath its businesslike silhouette. Its 4.0-liter V8 biturbo engine, part of the EA824 family co-developed with Bentley, delivered 420–450 hp (depending on model year) and a meaty 550 Nm of torque from as low as 1,400 rpm. Mated to a fast-shifting 7-speed S tronic dual-clutch transmission and the quattro all-wheel-drive system, it catapulted from 0 to 100 km/h in just 4.4 seconds—performance that rivaled many supercars of the time.
But the S6 was more than straight-line speed. The quattro system provided tenacious grip, while the available adaptive air suspension balanced comfort and control with ease. Body control was tight, steering responsive if slightly muted, and optional torque vectoring helped rotate the car with surprising agility for its size. It felt composed, even in spirited mountain driving, and supremely stable at high speeds on the autobahn.
The S6 was a wolf in a Brioni suit—an executive express that delivered brutal pace when summoned, yet cruised quietly and elegantly the rest of the time. It was fast, refined, and impressively discreet, engineered for the driver who wanted performance without sacrificing dignity or daily comfort.
Body Styles
The Audi S6 was offered in two distinct body styles: the four-door sedan and the five-door Avant wagon. Both featured clean proportions, strong shoulder lines, and muscular haunches. The sedan embodied the executive ideal with a classic long-hood, short-deck silhouette, while the Avant offered enhanced practicality without compromising elegance. Signature S-model cues included aluminum-look mirror housings, unique front and rear bumpers, a platinum grey single-frame grille, quad exhaust outlets, and discreet badging. Measuring just under five meters, the S6 combined luxury presence with understated aggression—never shouty, always poised.
Model Name Meaning (Manufacturer)
The “S” prefix identifies the model as a performance evolution of Audi’s core A6 series, positioned above the standard trims but below RS-level extremes. The number “6” designates its size class within Audi’s hierarchy, placing it in the upper executive segment between the A4/S4 and A8/S8.
Body & Interior Colors and Rims
The S6’s exterior palette emphasized sophistication with shades like Glacier White, Daytona Gray Pearl, Moonlight Blue, and Brilliant Black. Exclusive S options included Misano Red and Sepang Blue, which added visual punch without veering into ostentation. Optional black optic packages replaced chrome elements with gloss black trim, darkened the grille surround, and added black window frames for a stealthier look.
Inside, the S6 featured Valcona leather upholstery in Black, Lunar Silver, or Arras Red, with diamond stitching and contrasting piping available on higher trims. Brushed aluminum and carbon atlas were standard inlays, while layered wood veneers offered a warmer atmosphere for those preferring classic luxury. S6-specific digital instrumentation, flat-bottom steering wheels, and illuminated door sills reinforced the performance theme without overpowering the cabin’s elegant simplicity. The dual-cockpit dashboard and MMI interface were ergonomically designed and visually cohesive.
Wheel sizes ranged from 19 to 20 inches. Standard five-parallel spoke designs featured a titanium finish, while optional wheels included Y-spoke and double-spoke variants in machined or darkened treatments. The wheels filled the subtly flared arches well, contributing to the S6’s confident stance and silent athleticism.

vs Competitors
The Audi S6 stood between the brutal muscle of the Mercedes-AMG E43 and the balanced sharpness of the BMW 550i xDrive. It lacked the rear-drive flair of the BMW but made up for it with superior interior execution and all-weather grip thanks to quattro. Compared to the AMG, it was quieter, more cohesive in ride and handling, and less ostentatious—better suited for executives who preferred power under control rather than spectacle. Against all three, the S6 offered a singular proposition: supercar-like pace in an elegant shell, with restrained style and class-leading interior technology. It was the definitive autobahn weapon in a suit and tie.
Fun Fact
Despite its V8 power and blistering acceleration, the S6 used cylinder deactivation technology—shutting off four cylinders under light load—to enhance fuel economy. This discreet tech helped the S6 cruise like a V4 when calm, and roar like a V8 when provoked, proving that performance and efficiency could indeed coexist under one hood.
