The stand-alone 1995 Audi S6 is essentially the old Audi S4 rebadged, since the 100 platform on which it was based was going through a renaming transition to the A6. As such, the 1995 S6 is virtually identical to the 1994 S4. A mid-size luxury performance-oriented sedan (and the rare wagon, mostly sold in Europe), the S6 featured a 2.2-liter, 227-hp turbocharged I5 engine and standard 6-speed manual transmission. With sports-tuned suspension, springs, and shocks, and dual exhaust pipes, the S6 boasted 0-60 in six seconds. Quattro all-wheel drive turned the commuter sedan into an outdoor all-weather, all-season car, sure-footed in any condition.

Though the ride was firmer and performed optimally in highway driving, city roads were relatively smooth, thanks not only to Audi engineering, but its attention to comfort and luxury on the inside. The 1995 S6 came standard with leather seats, cruise control, intermittent wipers, power heated mirrors, a power sunroof, keyless entry, an alarm system, and the spoil-yourself heated front and rear seats. There was virtually nothing left for the options list except for a CD changer.

As with the S4, owners of the 1995 S6 praise its precise handling, solid feel behind the wheel, and confident grip on the road. They report little body roll and expert cornering capability. The most frequent complaint was turbo lag, though once the S6 got into gear, it was pleasingly fast. High marks also go to the comfortable and roomy interior and the quattro technology. Some criticisms went to the soft braking and electrical system problems. As with all Audis, repairs and parts are jaw-dropping expensive.
