The 2018 Audi S8 Sedan makes for an excellent contender in the fullsize sedan. With a single on offer, the Audi S8 has a base MSRP of $115,900, competing directly with the Mercedes-Benz AMG S 63 Sedan, the BMW Alpina B7, and the Jaguar XJR575. Only a 4.0L turbocharged V8 engine is offered, mated to an 8-speed automatic transmission. Together, they produce 605 horsepower and 517 lb-ft of torque. Accelerating from 0-60 in 3.7 seconds, the S8 Sedan maintains a combined fuel economy of 18 MPG. Audi offers the S8 Sedan in 12 stunning colors, with the Oolong Gray Metallic being a particular favorite of ours.
