It’s a quiet year for the Audi A8. Audi’s full-size luxury sedan gets a bit more standard equipment and some streamlined options packages for 2021, but it otherwise remains what it always has been: a handsome marriage of style, technology, and comfort.
You want comfort? Check out items like the optional heated massaging footrest. Cool tech? One look at the digital gauges and you’ll be hooked. And all it takes is one drive down a twisty two-lane comprehend the value of the predictive active suspension, which also plays a role in the safety of the A8. Here’s how: If this large Audi luxury sedan senses an imminent side collision, the active suspension lifts the chassis by 3.1 inches (within a half-second) to expose the strongest part of the structure to the brunt of the impact.
The all-wheel-drive Audi A8 is available in three ways. The A8 55 TFSI is powered by a turbocharged 3.0-liter V6 with 335 horsepower. The A8 60 TFSI e PHEV is a plug-in hybrid model with 443 horsepower and an electric range of about 17 miles. The top offering is the A8 60 TFSI, which is powered by a turbocharged 4.0-liter V8 with a whopping 453 horsepower.
If you’re looking for the 563-horsepower Audi S8, it’s reviewed separately on Autotrader.com.
Every new A8 coming to the United States from Audi’s plant in Neckarsulm, Germany, is the long-wheelbase version. BMW and Mercedes-Benz also sell the long-wheelbase versions of their large sedans in the U.S.
What’s New for 2021?
All Audi A8s get power front seats with 22-way adjustability for 2021. Beyond that, a top-view camera is now standard, and the A8 60 TFSI model has been upgraded with Sport exterior kit, Matrix headlights, and Valcona leather.

Environmental Protection Agency (EPA) fuel economy hasn’t been released yet for the 2021 A8, but we expect it to the stay the same because the cars are the unchanged mechanically.

Standard Features & Options
The 2021 Audi A8 55 TSFI ($86,500, plus $995 destination) comes with 19-in alloy wheels, adaptive air suspension, a top-view camera, full LED exterior lighting, a heat-insulated windshield, keyless entry, a panoramic sunroof, power soft-close doors, and a power-operated trunk. Inside, standard highlights include leather upholstery, quad-zone automatic climate control, Drive Select (adjustable steering, suspension, transmission and throttle settings), variable-ratio steering, 22-way power-adjustable front seats, digital Virtual Cockpit gauges with navigation, and standard Apple CarPlay/Android Auto. The stereo is a Bang & Olufsen unit with 17 speakers.
The A8 60 TSFI e ($94,905) adds the V6 plug-in hybrid drivetrain. A Rear Seat Connectivity package includes dual tablets, a rear DVD changer, a power outlet, and two rear USB ports.
The A8 60 TSFI ($97,905) model has an abundance of extra features to go with its stout V8 power. The Executive package includes blind-spot monitoring with rear cross-traffic alert, dual-pane acoustic glass and a heated steering wheel. The Driver Assistance package brings adaptive cruise control and active lane-keeping assistance along with Intersection Assist and Road Sign Recognition.
Of the two available Rear Seat Comfort packages, the most luxurious is the 4-seat Executive version of the A8 60 TSFI e PHEV and A8 60 TSFI models, which includes folding rear tables, reclining/ventilated/massaging rear seats, and remote controls that allow you to adjust the climate, lighting, and even the fore/aft location of the front passenger seat. This is also where the lucky rear passenger can enjoy the heated/massaging footrest.
Other options include 20- or 21-inch wheels and a 23-speaker Bang & Olufsen surround-sound audio system with 1,920 watts of power.
While we are in love with the A8’s spacious and elegant interior, we’d be remiss to not mention that its trunk, at 12.5 cubic feet, is on the small side. The S-Class Mercedes and Lexus LS 500 have much more cargo capacity – 16.3 and 17.0 cubic feet, respectively. Also worth noting: The A8 PHEV’s trunk is only 10.4 cubic feet because of the 14.1-kWh battery.
Standard safety equipment on the 2021 Audi A8 includes seven airbags, including a front-center airbag. Pre Sense (standard in all Audi cars) is perhaps the most notable standard safety feature; it automatically closes the sunroof and windows and cinches the seat belts for added occupant protection before an impending collision. Front and rear parking sensors also are standard, and although they are technically not safety hardware, they will help protect the A8 from bumper dings, as will the standard new (and very handy) top-view 360-degree camera.
The Audi A8 has not been crash-tested by the National Highway Traffic Safety Administration or the Insurance Insurance Institute for Highway Safety, but that is not a cause for concern.
Behind the Wheel
The A8 has a quiet and opulent cabin, with an understated design and abundant technologies. Materials are top-notch, and every switch or control operates with a precisely engineered feel. The haptic touchscreens have tactile and audible feedback, and passenger space is in abundant supply.
The driving experience of the 2021 Audi A8 is best characterized as smooth and refined, with more than ample power (especially in the V8-powered A8 60 TFSI models). Handling dynamics are impressively buttoned-down, although the response is more satisfying than exciting. Rear-wheel steering, part of the Black Optic Package, makes the A8 feel smaller than it is by helping to tighten this large sedan’s turning radius.
If ever there was a car designed for comfortable Interstate travel, the Audi A8 is it. As stated, it gobbles up the miles with ease, and it’s so quiet and smooth and solidly built that it makes 75 or 80 mph feel like about 60. No surprise that this sedan comes from the land of the high-speed Autobahn.
Other Cars to Consider
