The 2018 Audi S5 Sportback makes for an excellent contender in the compact sedan class. With 2 trims on offer, the Audi S5 Sportback has a base MSRP of $54,400, with prices going all the way up to MSRP $58,800, competing directly with the BMW 3 Series Sedan, the Mercedes-Benz AMG C 43 Sedan, and the Kia Stinger GT Sedan.
