The 2016 Audi S6 Sedan makes for an excellent contender in the midsize sedan class. With two trims on offer, the 2016 Audi S6 Sedan has a base MSRP of $70,900 competing directly with the Lexus GS F and the BMW 550i. Only a 4.0L turbocharged V8 engine is offered, mated to a 7-speed automatic transmission. Together, they produce 450 horsepower and 406 lb-ft of torque. Accelerating from 0-60 in 4.1 seconds, the Audi S6 Sedan maintains a combined fuel economy of 21 MPG. Audi offers the S6 Sedan in 12 stunning colors, with the Brilliant Black being a particular favorite of ours.
