Our take, from owner reports
Owners of the C8 S6 broadly praise the car's power delivery, describing it as feeling like a jet and faster than advertised, with the electric supercharger and 48V mild hybrid system credited for eliminating turbo lag.
7 problems reported (1 recurrent, 6 isolated) · high confidence
Described as nothing but problems and a lot.
Requiring two weeks at the dealer to clean.
Insufficient owner data available to declare a consensus. Partial signal: one owner specifically praised their 2020 Navarro Blue with Rotor Gray interior, noting it was one of only 24 sold in the USA that year, and described the engine as different from the RS5 with its electric supercharger and 48V mild hybrid. Another owner highlighted the 2025 S6 Premium Plus with white exterior and red stitching as preferable to the Prestige trim they test drove.
Owners compare it most often with the Audi A6, Audi A7, Audi S5, Audi RS5 and Audi SQ8.

Owners of the C8 S6 broadly praise the car's power delivery, describing it as feeling like a jet and faster than advertised, with the electric supercharger and 48V mild hybrid system credited for eliminating turbo lag. The car is called an instant classic and a rare bird, with several owners calling it a huge upgrade over the A6. Criticism centers on the touchscreen-heavy interior, which some find less usable and more plasticky than the previous generation, and on the excessive start/stop functionality. Early C8 owners reported AC and ECM problems, while later discussion focuses more on water pump failures and software issues in the newest model year. The 2025 model year draws significant criticism for its new entertainment system, which multiple owners describe as having a lot of problems.
Owners position the C8 S6 as more powerful and more of a real driving car than the S5, with one owner stating the S6 is way more powerful and worth the cost difference unless you want the newest bells and whistles. Against the A7, owners note the S6 would hold its value slightly higher but the A7 is more practical with its hatchback opening. One owner cross-shopping a BMW M3 was told it would be crazy to switch from the G80 to an S6. The S6 is described as more adult-like compared to the S5, which one owner characterized as seeming like a car for a 20 year old.
Insufficient owner data available. One owner noted the 2025 S6 Premium Plus with white paint and red stitching was liked better than the black Prestige they test drove. Another owner mentioned the S6 has the electric supercharger that spools up before the turbo to boost low end torque and reduce lag, plus the 48V mild hybrid, and that the car is faster than advertised.
Owners strongly recommend purchasing an extended warranty for this generation, with one owner stating you should always get one if you plan to keep the car past factory protection, and another advising to extend coverage before expiration rather than trying to buy after it lapses. One owner emphasized reading over extended warranty choices carefully, calling engine, transmission, electric, and suspension coverage a must for these cars. Owners suggest finding a reputable euro shop for out-of-warranty service to save roughly half versus dealership rates. One owner recommended reserving $10,000 to $15,000 for potential repairs if buying without a warranty. For winter driving, owners recommend sizing down to 20-inch wheels with winter tires, with Pirelli Scorpion Winters specifically praised for performing spectacularly in upstate New York and New England conditions. One owner runs Pilot Sport all-seasons year-round in the Midwest with no complaints.
One owner reported a 2025 S6 recall involving the torsion bar in front seat belt retractors possibly damaged during production, with dealers replacing affected seat belts free of charge. An owner noted the S6 has fake exhaust tips that are not connected to the pipes, though both pipes on each side do exit straight out of the rear. Owners repeatedly note that dealership service rates vary widely, with some reporting $300 per hour while others cite $185 to $210 per hour, and independent euro shops charging $100 to $150 per hour. One owner mentioned the S badge on the front grille shows only the S without the number 6. Analysis based on approximately 81 substantive owner discussions about this generation.
