It’s been on the market long enough to hit the normal refresh cycle, but the A6 stills feels very current. It’s also plenty energetic, bursting to 60 mph in 5.4 seconds and lobbing through the quarter-mile in as little as 13.9 seconds, according to some tests. Sure, all-wheel drive helps these standing-start sprints, but the muscular V-6 TDI and smart-shifting eight-speed automatic transmission are the prime reasons the A6 has such pace. Even better, stick to normal speeds and the A6 averages 29 mpg—30 mpg if you’re careful. As for comfort, the A6 fills any reasonable luxury demand, offering the innate satisfaction of intelligent sizing and premium materials through a full slate of electronic frills— albeit mainly in pricey option packages. It’s a must-sample choice for power trippers wanting both fuel economy and luxury in their ride.
