2021 Audi A6 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

  • 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.

Very nice upscale vehicle. Bought as a previously

Very nice upscale vehicle. Bought as a previously 2 yr leased auto, avoiding new car price and immediate depreciation. V-6 engine has no hesitation and quietness is excellent. My only two negatives are lack of storage for incidentals and a bit quirky audio that may reset from time to time ( must wait for it to go through a cycle). It has a mind of its own. Overall, excellent vehicle.

Beautiful Meh

Leased the car for looks new in 2021. Now 2023 with 28k miles. Perfect? No. Awful? Hardly. Many recalls but no maintenance issues whatsoever. Biggest complaint is the auto-start stop and that the electronics are quirky (pre-set destinations reset frequently) car is comfortable, quiet, quick, and get OK gas mileage (would assume better with 2.0 4cyl.) I often switch between this and a 2017 Honda Accord and to be honest I can't tell much of a difference other than noise and quickness. Will buy it off lease (got it before the residual values rose exponentially) and will keep it indefinitely.
