Our expert's take
By Cars.com Editors
Full article

What Is the 2021 Audi A8?

Audi’s flagship sedan, the A8, is a rival to the Mercedes-Benz S-Class, BMW 7 Series and Lexus LS. The car’s base engine is a 335-horsepower, turbocharged 3.0-liter V-6; a 453-hp, twin-turbocharged 4.0-liter V-8 is available. Audi also sells a plug-in hybrid version of the A8 that can travel around 17 miles on electric power alone. The high-output S8 — the performance version of this full-size luxury sedan — has a 563-hp V-8. All powertrains work with an eight-speed automatic transmission, and all-wheel drive is standard. 

What’s New on the 2021 Audi A8?

New standard features include 22-way power-adjustable front seats and a 360-degree camera system with a virtual viewing mode. The S8 now comes with standard front heated armrests and 21-inch wheels with summer tires. 

What Features in the 2021 Audi A8 Are Most Important?

Standard features include:

  • Adaptive air suspension
  • Panoramic moonroof
  • Leather upholstery
  • Heated and ventilated front seats
  • Four-zone automatic climate control
  • Power rear sunshades
  • Wood interior trim
  • Touchscreen navigation system
  • Bang & Olufsen stereo

Available features include:

  • Massaging, power-adjustable rear seats
  • In-cabin fragrance system
  • Heated steering wheel
  • Head-up display 
  • Blind spot warning 
  • Rear dual-tablet entertainment system
  • Night vision

Should I Buy the 2021 Audi A8?

If you have the means to afford a full-size luxury sedan, the A8 is worth a look. Its range of available powertrains is a plus, and its classy interior impresses. Some might find the design too conservative, however, and rivals offer similar levels of luxury.

  • S8 Incredible Sport Sedan

    Love the power ride quiet and comfort…it drives itself in traffic jams and is like a rocket on the highway. Interior comfort with massage seats and fit and finish was incredible.
