Pros: Impeccable interior materials; fine all-around build quality; quick acceleration with supercharged V6
Cons: Some complicated controls; prices escalate quickly as options are added; rear seat not as spacious as exterior size would suggest
CG Says: The 2018 Audi A6 is essentially unchanged. Keyless starting/entry and navigation are now standard on all models and horsepower for the A6 3.0T supercharged V6 increases from 333 to 340—the same as last year’s A6 3.0T Competition model. A6 and performance S6 are premium midsize sedans. The A6 2.0T is powered by a 252-horsepower turbocharged 2.0-liter four-cylinder engine. 2.0T has a 7-speed automated-manual transmission with front-wheel drive or an eight-speed automatic transmission with all-wheel drive. All 3.0T models have an eight-speed automatic transmission and all-wheel drive. The all-wheel-drive S6 packs a 450-hp turbocharged 4.0-liter V8 mated to a 7-speed automated manual. Available features for A6 and S6 include blind-spot alert, surround-view camera, head-up instrument display, and adaptive cruise control. The 2018 Audi A6 and S6 excel for their high levels of polish and sophistication that strikes a nice blend between the performance-oriented BMW 5-Series and coddling Mercedes-Benz E-Class. First-rate interior accommodations and a remarkably hushed cabin add to the experience. However, rear-seat room is less than impressive, and reasonable base prices quickly skyrocket as you add expensive standalone and packaged options. Unfortunately, some of the more desirable luxury and convenience items will force you into the high-end 3.0T model. Still, for those with the means to acquire such a vehicle, A6 and S6 are extremely appealing premium-midsize sedans.
