Expert 2021 Audi S6 review

our expert's take

What Is the 2021 Audi A6?

The Audi A6 is a mid-size luxury sedan that bridges the gap between the German automaker’s smaller A4 sedan and the full-size A8 sedan. Engines range from mild to wild, with the S6’s 444-horsepower, twin-turbocharged 2.9-liter V-6 falling into the latter category. 

Base sedans are powered by a 248-hp, turbocharged 2.0-liter four-cylinder engine that works with a seven-speed dual-clutch automatic transmission. A 335-hp, turbocharged 3.0-liter V-6 is available, and this engine also powers the Allroad wagon. All-wheel drive is standard. Competitors include the BMW 5 Series and Mercedes-Benz E-Class

What’s New on the 2021 Audi A6?

The A6 was redesigned for the 2019 model year; changes for 2021 consist of the reshuffling of some features within option packages. 

What Features in the 2021 Audi A6 Are Most Important?

Standard features include:

  • Dual center touchscreens
  • Leather seating surfaces
  • Power moonroof 
  • Heated front seats
  • Tri-zone automatic climate control
  • Apple CarPlay, Android Auto smartphone connectivity

Available features include:

  • Lane-keeping assist
  • Adaptive cruise control
  • Bang & Olufsen premium stereo
  • Head-up display
  • Heated steering wheel
  • 360-degree camera system
  • Sport suspension

Should I Buy the 2021 Audi A6?

With a choice of body styles and powertrains, there’s probably an A6 that will meet your luxury car needs. Interior quality is a familiar Audi highlight, but we’re less impressed by the A6’s adoption of many touch-sensitive controls. The sedan’s trunk is also on the small side.

Sophisticated Performance Sedan

I purchased the 2021 Audi S6 Prestige after looking at similar vehicles in the class like the BMW M550i and Mercedes Benz AMG E53. My choice came down to performance, reliability, look, and value. I have had the car for 4 weeks and have no regrets. My highway gas mileage has been as high as 31 miles per gallon which is terrific for a car with this type of performance. The controls are easy to learn and the car feels like it is floating when driving it. I like that it is a performance vehicle with an understated look. Some may want a car with a more aggressive look but I like the understated, traditional sedan look. So far I would recommend this car.
