Having heart-thumping power is one thing but keeping it on the road is another. Get all-weather traction thanks to the available Quattro AWD, which balances the engine power across all four wheels based on grip conditions. The first of three engines, a 252 hp turbocharged 2.0L four-cylinder, and FWD get the job done around town. Or, at 333 hp, a 3.0L supercharged V6 engine—bumped to 340 hp in 2018 Audi A6 Competition models—should easily handle any high-performance demands.

4. Luxurious interior
