Audi does not build many cars like the Audi S6: a 4-door saloon/sedan, / 5-door Avant (estate/wagon) with 2.2 , built from 1994 to 2025 when airbags, anti-lock brakes and Japanese build quality became the world standard.
Where it came from
The Audi S6 is a high-performance variant of the Audi A6, an executive car produced by German automaker Audi. It went on sale in 1994, shortly after the "A6" designation was introduced, replacing the "100" nameplate.
The original S6 was largely identical to the outgoing Audi S4 (C4) (Often referred to as the Ur-S4), with the only visible differences being new body-cladding and badging. In certain markets where the even-higher performance RS6 (which is also based on the A6) is not sold, the S6 serves as the most powerful trim level for the A6 lineup. The S6, like all Audi "S" models, is fitted as standard with Audi's trademark quattro four-wheel drive (4WD) system, using the Torsen-based permanent 4WD.
Under the skin
Under the skin sits 2.2 other versions carried different engines, listed in the specification table below. Kerb weight is 1730 kg. The gearbox is a 5-speed manual, / 6-speed manual, / 4-speed automatic. The wheelbase is 2692 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
In context
Where it sits in Audi's history is not in doubt: it was built at Neckarsulm, Germany. On a showroom list of its day it stood against the Subaru Outback, the Toyota RAV4, the Toyota Tacoma. Nearby in the Audi catalogue sit the Audi 200 and the Audi 225.
The money
On the used market today a Audi S6 typically changes hands for $17,700–$65,000, and running it — fuel and maintenance at its age — costs about $3,805–$8,045 a year. Insurance sits around $1,730–$3,570 a year. The figures are class-level estimates from the federal record, with the formula on the methodology page; the model-year pages carry complaints, recalls and repair costs year by year.
