From behind the wheel, the first thing you notice about the Audi S6 Audi is how effortlessly it marries everyday comfort with genuine performance. The twin-turbo V6 hums at idle, then pulls hard as you feed in throttle. This is the kind of car that makes you take the long way home. On paper, the Audi S6 Audi competes with the BMW M550i and Mercedes-AMG E53. In practice, it carves its own lane—less aggressive than the BMW, more planted than the Mercedes, and priced to keep the accountants at Audi happy. Over a week of testing through canyon roads and LA freeways, the S6 Audi proved it can do it all, but not without a few compromises.
The 2.9-liter twin-turbo V6 produces 444 horsepower and 443 lb-ft of torque, good for a claimed 0-60 mph in 3.9 seconds. The eight-speed automatic shifts smoothly, and the Quattro all-wheel drive provides immense grip. Yet the steering, while accurate, lacks the tactile communication of a true sports sedan. The Audi S6 Audi is fast, but it's not a scalpel. It's a sledgehammer with a velvet glove.
What Makes the Audi S6 Stand Out?
The biggest selling point of the Audi S6 Audi is its dual nature. In Comfort mode, it glides over potholes with an isolation that rivals the A8. The cabin is whisper-quiet, the seats are supportive, and the technology suite—including the Virtual Cockpit and dual touchscreens—is intuitive after a day of use. Switch to Dynamic mode, and the exhaust note deepens, the suspension stiffens, and the transmission holds gears. For daily commuting, the S6 is a luxury car. For a weekend blast, it's a capable performer. That versatility is rare in this segment.
But the Audi S6 Audi also stands out for what it's missing. Unlike its rivals, it doesn't offer a V8 option. The BMW M550i has a thunderous 523-hp V8. The E53 uses a straight-six hybrid. Audi chose downsizing, and while the V6 is potent, it lacks the character of a larger engine. The sound is artificial and processed. Enthusiasts who love a visceral engine note will be disappointed. The Audi S6 Audi is quick, but not exciting in the way the M550i is.
Interior and Technology: A Mixed Bag
Step inside the Audi S6 Audi, and the quality impresses. Leather, Alcantara, and brushed aluminum cover every surface. The seats are heated, ventilated, and massaging. The rear seats offer adequate legroom for two adults, though the middle position is tight. The trunk measures 13.7 cubic feet—reasonable for the class.
However, the technology has some quirks. The dual touchscreens (10.1 and 8.6 inches) control infotainment and climate. They look sleek but attract fingerprints and require a firm press. While driving, adjusting the volume or changing a setting takes your eyes off the road too long. The mandatory gesture control is gimmicky. A dedicated knob would be better. For a 2024 model, the Audi S6 Audi should have more intuitive controls. Still, the audio system (Bang & Olufsen optional) is superb, and the navigation integrates Google Earth views.
Pricing and Competition
The 2024 Audi S6 Audi starts at around $80,000. Our test car, with the Premium Plus package and several options, stickered for $88,000. That undercuts the BMW M550i by roughly $6,000, but matches the Mercedes E53. The S6 offers standard Quattro and adaptive suspension, while the competition charges for similar equipment. Resale value is strong, though depreciation is steeper than a BMW's. For buyers focused on value, the Audi S6 Audi is a smart choice, but the lack of an optional V8 limits its appeal among purists.
The Verdict: Pros, Cons, and Whether You Should Buy One
Pros
- Quiet, comfortable ride in Comfort mode
- Quick acceleration and secure handling
- High-quality interior with excellent materials
- Competitive pricing for the segment
Cons
- Artificial engine sound; no V8 option
- Touchscreen controls distract while driving
- Rear seat space merely average
- Steering lacks feedback
Bottom Line: The Audi S6 Audi is a well-rounded sport sedan that excels at daily driving and occasional fun. It's not the most engaging car in its class, but it might be the most livable. If you prioritize comfort, technology, and value over raw thrills, it's a strong contender. If you want a car that talks to you on every corner, look at the BMW or a used Panamera.

What the Audi S6 Audi Costs Over Three Years of Ownership
Beyond the sticker price, the Audi S6 Audi carries predictable ownership costs that help you budget. Depreciation is the biggest hit: after three years, expect the Audi S6 Audi to retain about 55-60% of its original value, which is slightly below the BMW M550i but better than the Mercedes E53. Insurance for the S6 runs around $2,000 per year for a good driver with a clean record, according to major insurers. Fuel costs are moderate for the class; the EPA rates the S6 at 18/28 mpg (city/highway), so expect to spend about $2,400 annually if you drive 15,000 miles. Routine maintenance is pricey: an oil change costs around $250 at the dealer, and the 40,000-mile service can exceed $1,000. Audi’s Carefree Maintenance plan covers the first two years, which helps. Overall, owning the Audi S6 Audi for three years will cost roughly $25,000 to $30,000 in depreciation, insurance, fuel, and maintenance, depending on options and driving habits. That’s competitive with its rivals, though the initial purchase price remains the deciding factor.
