The Audi 2018 S6 luxury sport sedan brings with it that most intoxicating of automotive virtues: power. How much (or how little) power there is can define a car's character and place it in the automotive hierarchy of speed. The S6 has 450 horses at its disposal, and that's good enough to propel it quite high in that hierarchy.
The S6 is based on Audi's A6 sedan and slots between the smaller S4 and Audi's flagship S8. It's in the "just right" size range, alongside cars such as the BMW 5 Series and Mercedes-Benz E-Class. With its stout chassis supported by optional all-wheel drive, the S6 is the perfect platform for high-performance hijinks.
While A6 gets along with either a four- or six-cylinder engine, the S6's heart is Audi's mighty direct-injected, twin-turbocharged 4.0-liter V8 engine rated at 450 horsepower. A miracle of compact packaging, the Audi V8 stuffs its two turbos in the valley between the two cylinder banks.
Using Audi's S tronic dual-clutch, seven-speed automatic transmission and, naturally, all-wheel drive, the S6 can make the most of its prodigious power. This is a startlingly fast car capable of slingshot launches to 60 mph in 4 seconds. But there's more to the S6 than just mastery of stoplight drag races. The engine produces torque by the train load; it always feels ready to shoot the car forward without dropping more than one or two gears.
The S6 is also civilized. Everything that can be covered in leather is. The interior is roomy and the ride is comfortable. The S6 can do a pretty good imitation of an A6 when it's asked to. Of particular note is Audi's outstanding Multimedia Interface (MMI) that uses brilliant graphics and a relatively intuitive interface to keep the driver informed.
An obsession with speed is best exercised with safety in mind and an eye to not spend too much to indulge in it. So use the buying tools here on Edmunds to get the best deal on your new S6.
