Audi A6 Versus the Competition

Audi A6 vs. BMW 5 Series

The BMW 5 Series is an excellent luxury midsize car with across-the-board appeal. It has a lengthy list of blistering powertrain options, and the range-topping BMW M models rival the Audi S6 and RS for power and performance. The BMW also impresses with its thrilling handling, silky ride, and impressive cabin materials. The Audi is a good vehicle, but the BMW is better.

Compare the A6 and 5 Series »

Audi A6 vs. Audi A7

The Audi A7 is a luxury large car that has a lot in common with its sibling. Both vehicles have a dual-screen infotainment system and sumptuous cabin materials. Both also have performance-oriented models: the Audi S6 and S7, as well as high-performance RS models. However, the A7’s liftback design gives it more cargo space than the A6 or S6 sedans. There’s no wrong choice between these Audis.

A6 Interior: High-End Cabin, Tiny Trunk

A6 Cargo Space

The A6 and S6 sedans have 13.7 cubic feet of trunk space. That's small for the class, but most reviewers have no complaints about the size, and the standard split-folding rear seat can be used to create more space. A power trunk lid is available. The RS 6 wagon has a roomier 30 cubic feet of cargo space behind its rear seats and even more with those seats folded.

How Many People Does the A6 Seat?

Regardless of body style, this car can accommodate five people. Leather upholstery comes standard, and front-row occupants are treated to eight-way power-adjustable heated seats. Upgrades include additional power adjustments for the front seats, ventilated and massaging front seats, heated rear seats, upgraded leather upholstery, and a heated steering wheel.

Both rows have enough head- and legroom for most adults to sit comfortably. The seats are well-cushioned, and the long list of upgrades help to maximize comfort.

A6 and Child Car Seats

This sedan has two complete sets of LATCH connectors for the rear outboard seats, plus a single tether for the rear middle seat. The Insurance Institute for Highway Safety gave this LATCH setup the highest rating of Good for its ease of use.

A6 Interior Quality

With its premium cabin materials, soft leather surfaces, and cutting-edge tech features, the A6’s cabin oozes luxury.

A6 Infotainment, Bluetooth, and Navigation

This Audi’s MMI infotainment system uses dual touch screens with haptic feedback, meaning touch-based clicks or vibrations signal that your input has registered. The system works well, with the upper screen displaying navigation and audio functions and the lower screen showing climate and other settings. While the system is responsive and offers crisp graphics, it can be distracting to use while driving.

  • Standard infotainment features: an 8.8-inch upper touch screen, an 8.6-inch lower touch screen, Amazon Alexa, Apple CarPlay, Android Auto, a navigation system, USB ports, HD Radio, satellite radio, a 10-speaker stereo, and Bluetooth
  • Available infotainment features: a 10.1-inch upper touch screen, a 16- or 19-speaker Bang & Olufsen stereo, wireless device charging, and a 12.3-inch digital driver display (Audi's Virtual Cockpit)
  • Additional standard features: tri-zone automatic climate control, a panoramic sunroof, and proximity keyless entry
  • Additional available features: quad-zone automatic climate control

A6 Performance: Mild-Hybrid, Major Power

A6 Engine

There are four engine choices for this vehicle. The A6 can be had with a 2.0-liter four-cylinder or a 3.0-liter V6, and both are turbocharged. The four-cylinder makes 248 horsepower and 273 pound-feet of torque, while the V6 has 335 horsepower and 369 pound-feet of torque. Both have mild-hybrid setups and are paired with a seven-speed dual-clutch automatic transmission.

The turbo-four engine is perfectly fine for daily driving, and outside of feeling a touch strained on the highway, it supplies ample power for most driving situations. The V6 helps deliver more authoritative acceleration.

For something spicier, you might consider upgrading to the S6 or RS 6 Avant. The Audi S6 has a 2.9-liter twin-turbocharged V6 engine rated at 444 horsepower and 443 pound-feet of torque. It helps the S6 sprint from zero to 60 mph in 4.4 seconds and hit a top speed of 155 mph.

The strongest engine in the mix comes in the high-performance Audi RS 6 Avant. This wagon has a 4.0-liter twin-turbo V8 with a blistering 591 horsepower and 590 pound-feet of torque. The RS can go from zero to 60 mph in 3.5 seconds and has a top speed of 190 mph. Both the S6 and RS 6 have an eight-speed automatic transmission.

A6 Gas Mileage

The A6 gets an EPA-rated 23 mpg in the city and 31 mpg on the highway when paired with its standard four-cylinder engine. With the optional V6 engine, fuel economy dips to 22/29 mpg city/highway. Those are decent ratings considering this Audi comes standard with Quattro all-wheel drive. The performance-oriented S6 and RS 6 Avant get 18/28 and 15/22 mpg, respectively.

A6 Ride and Handling

The A6 provides a composed and comfortable ride, and it's easy to maneuver around turns. Few road flaws penetrate the cabin. Audi's Quattro all-wheel drive is standard.

A6 Dimensions and Weight

The A6 is 16.2 feet long. Its curb weight ranges from 4,101 to 4,266 pounds. The Audi S6 sedan is 16.3 feet long with a curb weight of 4,486 pounds. The Audi RS 6 wagon is 16.4 feet long, and it has a curb weight of 4,960 pounds.

Where Is the 2021 Audi A6 Built?

Audi builds the 2021 A6 in Germany.

Which Audi A6 Model Is Right for Me?

Audi makes the 2021 A6 in three trim levels: Premium, Premium Plus, and Prestige. The performance-oriented Audi S6 comes in Premium Plus and Prestige trims, and the high-performance Audi RS 6 Avant comes in a single trim. The RS 6 Avant is a wagon, while the rest are sedans.

The major difference between the A6, S6, and RS 6 relates to powertrain. The Audi A6 has a four-cylinder or V6 engine. The Audi S6 has a twin-turbocharged V6 engine, and the RS 6 features a twin-turbo V8. Audi’s Quattro all-wheel drive is standard throughout the lineup.

Every model is well-equipped, but it may be worth upgrading to the Premium Plus trim to get Audi's Virtual Cockpit, which replaces the traditional gauge cluster with a high-tech digital display.

Audi also produces the Audi A6 Allroad wagon, which we review separately. This model represents a more affordable way to get an A6 wagon than the RS 6 Avant, though you lose that model's incredible performance for that reduced price.

Audi A6 Premium

The entry-level Premium trim has a starting MSRP of $54,900. Standard equipment includes the MMI infotainment system, an 8.8-inch upper touch screen, an 8.6-inch lower touch screen, a navigation system, Android Auto, Amazon Alexa, Apple CarPlay, a 10-speaker stereo, satellite radio, HD Radio, USB ports, and Bluetooth.

The Premium also has leather seats, heated and eight-way power-adjustable front seats, a panoramic sunroof, tri-zone automatic climate control, proximity keyless entry, Audi Pre Sense Basic, Audi Pre Sense Front, front and rear parking sensors, rain-sensing windshield wipers, and lane departure warning.

The Convenience package adds wireless device charging (Audi Phone Box), a 10.1-inch upper touch screen, a hands-free trunk lid, Audi Side Assist, Audi Pre Sense Rear, vehicle exit warning, a surround-view parking camera system, and a heated steering wheel. Adding the V6 engine costs $4,900.

Audi A6 Premium Plus

The Premium Plus retails for $58,800. It gains the Audi Virtual Cockpit, a 16-speaker Bang & Olufsen sound system, automatic high-beam headlights, lane keep assist, adaptive cruise control, and the contents of the Convenience package. The V6 raises the price by $4,900.

The Executive package adds quad-zone automatic climate control, ventilated front seats, heated rear seats, and a power trunk lid. The Driver Assistance package adds traffic sign recognition and intersection assist. The Sport package adds a sport-tuned suspension and larger alloy wheels.

Audi A6 Prestige

The Prestige (MSRP: $64,900) comes with a head-up display, adaptive headlights, power soft-closing doors, 12-way power-adjustable front seats, and the contents of the Executive and Driver Assistance packages. In the Prestige, getting the V6 bumps up the price by $4,600.

The Sport package remains available. The Luxury package adds massaging front seats, 18-way power-adjustable front seats, a leather-covered dashboard and console, Valcona leather upholstery, and a power rear-window sunshade. Models with the V6 engine can be equipped with an adaptive damping suspension and all-wheel steering.

Audi S6

The Audi S6 has a starting price of $74,400. Other than a twin-turbo V6 engine, the S6 Premium Plus and S6 Prestige are comparably equipped to their A6 counterparts. However, the S6 is available with an S Sport package that adds a sport exhaust, red brake calipers, a Quattro rear differential, and all-wheel steering. Other options include a 19-speaker Bang & Olufsen sound system and a night-vision camera.

Audi RS 6 Avant

The Audi RS 6 Avant wagon has a base MSRP of $109,000. In addition to performance upgrades such as a twin-turbocharged V8 engine, all-wheel steering, a performance-tuned suspension, and a Quattro rear sport differential, it has many of the Audi S6 Premium Plus’ standard equipment and options. Some RS-specific options are available too, such as carbon-ceramic brakes.

The Final Call

The 2021 Audi A6 is a top contender among luxury midsize cars. It has potent powertrain options and body styles that range from the S6 sedan to the RS 6 Avant wagon. Regardless, you’ll get a car with a punchy engine, a serene ride, and a handsome cabin. However, this is a highly competitive class. Before buying the Audi, it may be worth checking out its rivals from Mercedes-Benz and BMW.

Don’t just take our word for it. Check out comments from some of the reviews that drive our rankings and analysis.

  • "The 2021 Audi A6 is the German brand’s sophisticated player in the midsize luxury sedan segment, where it competes with the BMW 5 Series and Mercedes-Benz E-Class. Those rivals may outsell the A6, but this luxury sedan is highly attractive to executives seeking to stand out from the crowd." -- Autotrader
  • "While one-time rivals like the Lexus GS are being discontinued, the A6 still faces formidable competition in the BMW 5 Series and Mercedes-Benz E-Class. Those German competitors outsell the A6, but the Audi attracts with its excellent – and standard – quattro all-wheel-drive system. The 2021 Audi A6 also boasts innovative technology and excellent driving manners that split the difference between the sportiness of the BMW 5 Series and plushness of the Mercedes E-Class." -- Kelley Blue Book
  • "Comfortable, spacious, and well-equipped, the 2021 Audi A6 checks the critical boxes for a mid-size luxury car. Its cabin is lined with quality materials and fit and finish ranks among the best the premium automobile marketplace has to offer. The A6 also woos tech-savvy buyers with a plethora of displays, cameras, driver-assistance features, and convenience items sprinkled throughout the interior. What's missing here is the crisp and tossable handling dynamics that shine so brightly in the smaller A4 sedan and its two-door A5 siblings." -- Car and Driver
