2018 Audi S4 vs the competition

2018 BMW 340i -- The most powerful 3 Series before getting into M3 territory, this 320-hp sedan comes with rear-wheel drive as standard, or optional all-wheel drive.

2018 Infiniti Q50 Red Sport 400 -- Slightly more powerful than the S4, with 400 hp, but otherwise not in the same league in terms of quality, equipment, handling or youth.

2018 Jaguar XE S -- A supercharged V6 makes 340 hp. The rest of the car is similarly wonderful, except the cabin isn't at Audi's level.

2018 Mercedes-AMG C 43 -- With 362 hp and all-wheel drive as standard, this version of the C-Class is the most direct S4 competitor.

Used BMW M3 -- Take a look at BMW's certified pre-owned (CPO) program, since the ultimate compact sport sedan is within reach of those considering the S4's Prestige trim.
