Manufacturer's Suggested Retail Price (MSRP), also known as "sticker" price, is a recommended selling price that automakers give a new car that is above the invoice price paid by the dealer. It is a price that does not include any options that can be added to a particular car style. When shown as a range, the prices are starting MSRPs, without options, for multiple styles for that model.
This price range reflects for-sale prices on Cars.com for this particular make, model and year.
Best Bets get above-average mpg, class-average or better reliability, class-average or better crash-test ratings, and our recommendation.
These city and highway gas mileage estimates are for the model's standard trim configurations. Where there are optional features, packages or equipment that result in higher gas mileage, those fuel-economy estimates are not included here.

Vehicle Overview Audi is extending its "S" performance treatment from one model into a veritable series. Previously available only on the A4 as an S4, a high-performance variant will now be available on Audi's midsize A6, as the S6. Audi had previously announced it will build an S8 full-size variant.
Exterior There are no changes from the A6 to the S6, although the S6 gets special badging to boast its performance capabilities: a "V10" emblem on each front quarter panel, and an "S6" emblem front and rear. The front "S6" badge, mounted on the gargantuan grille, is somewhat lost amid the ocean of chrome.
Interior There are no changes from the A6.
Under the Hood Audi uses the same 420-horsepower, 5.2-liter V-10 in the S6 and S8. It's mated to a six-speed-automatic transmission that gives the driver the ability to shift gears manually and choose different driving modes, such as "Sport," to enhance performance. The V-10 represents an 85-hp boost from the biggest engine available in the A6, a 335-hp V-8.
The S6 and S8 also get Audi's "quattro" all-wheel-drive system.
Safety The S6 has all the elements of the A6: Sideguard head-curtain airbags, side-impact airbags, an electronic stability system and antilock brakes. In addition, side airbags for the rear seats are an option not available on the A6.
