Is the Audi A6 a Good Car?

The A6 is the vehicular equivalent of that friend you find mildly annoying at times because they’re really good at everything. Inside, it has an interior that’s upscale even by luxury-car standards, with two rows of spacious seats and plenty of user-friendly technology. You have three engine choices, all of which have more than enough power, and the A6 handles extremely well for a midsize sedan. It also gets above-average gas mileage, and its price tag is lower than several of its class rivals. Due to the A6's combination of space, family-friendly features, and perfect crash test scores, we named it our 2018 Best Luxury Midsize Car for Families.

Should I Buy the Audi A6?

You'd be hard-pressed to find a reason not to buy the A6. Among luxury midsize cars, the A6 is at or near the top of the pack in every category. There are luxury midsize cars that cost less than the A6, but they don’t provide nearly as much value as this Audi.

If you are going to shop around – and you might as well – then the Mercedes-Benz E-Class is a good car to look at. Like the A6, it excels in nearly every area, and though it’s among the most expensive cars in the class, it’s worth the cost. The Cadillac CTS is another good comparison. It costs a bit less than the A6, but it still delivers an engaging driving experience and has a high-quality interior.

Should I Buy a New or Used Audi A6?

Last redesigned for 2012, the Audi A6 has seen a few changes over the past few model years. You can likely save thousands of dollars by shopping for a used A6, though you'll want to sort through the differences from each year. For 2016, the A6 received updated styling inside and out, and the continuously variable automatic transmission was discontinued. Each of the three available engines got a good bump in horsepower, from 220 to 252, 310 to 333, and 420 to 450, respectively. Android Auto and Apple CarPlay became available with the 2017 model, and a new Competition trim with sport seats, a sport suspension, and sportier styling debuted. Audi also made a rearview camera and parking sensors standard for 2017 – you can find them in older models, you just have to hunt around.

The MMI infotainment system with navigation became standard for 2018, and the supercharged V6 engine received a 333 to 340 horsepower boost. If these changes aren't important to you, consider shopping for a used A6. To research other models in this generation, check out our reviews of the 2015, 2016, and 2017 Audi A6.

How Much Does the Audi A6 Cost?

The Audi A6 has a starting price of $49,700. That’s not the highest base price in the class, but it is above average. However, it’s worth noting that the class average is skewed somewhat because of a few low-ranking vehicles that cost about $8,000-$10,000 less than many peers. The A6 is competitively priced among vehicles at or near the top of the class rankings.

That was a long-winded way of saying that the A6 provides plenty of value for the money. Even the base trim is well-equipped, but you can step up to the Premium Plus (starting at $51,900) or Prestige (starting at $61,400) trims if you want more features. And if you want the most power, there are two high-performance variants: the S6 Premium Plus (starting at $71,900) and the S6 Prestige (starting at $74,400).

Audi A6 Versus the Competition

Which Is Better: Audi A6 or Mercedes-Benz E-Class?

The Mercedes-Benz E-Class is another vehicle with no real drawbacks, and it might be the A6’s biggest competition in this class. The E-Class has an interior so upscale you have to see it to believe it, and the already-comfortable seats have a number of premium upgrades available. The E-Class has a litany of features, including some that the A6 doesn’t offer, such as driver drowsiness monitoring and evasive steering assist. The E-Class’ trunk is smaller than the A6’s, however.

Like its Audi rival, this Mercedes features several engine options, though none are as fuel-efficient as the A6's. The E-Class delivers a smoother ride (some would say the best ride in the class), but it is a bit less athletic than the Audi. The Mercedes also costs a few thousand dollars more. If you’re choosing between them, let your personal preferences be the ultimate deciding factor.

Which Is Better: Audi A6 or Cadillac CTS?

The Cadillac CTS finishes in the middle of our luxury midsize car rankings, but that’s just a product of how competitive this class is, because this is another great vehicle. The CTS has a slightly lower price than the A6 but still comes packed with features like Apple CarPlay, Android Auto, a Teen Driver monitoring system, a rearview camera, three USB ports, an 8-inch touch screen, an 11-speaker sound system, and adaptive remote start.

The CTS has a slightly more powerful standard engine than the A6, but it isn't as smooth as the A6's base engine. Like the A6, the CTS offers more-powerful engines and has sharp handling and a comfortable ride. Its nicely styled interior has high-quality materials, but it isn't up to the A6's standards. The A6 and CTS are have many similarities, but the Audi is a little ahead of the Cadillac in most areas.

A6 Interior

How Many People Does the A6 Seat?

The A6 seats five people, and both rows of seats are supportive. A number of available seating upgrades improve the already-impressive level of comfort. Drivers have excellent outward visibility, and the rear seats provide more legroom than many competitors do.

A6 and Car Seats

There are two full sets of LATCH car-seat connectors, and the middle seat has a tether anchor. All three tether anchors are easy to find and are visually distinctive from other hardware in the car. Lower anchors are recessed into a plastic housing in the seats, so they are easy to find and maneuver around with little effort required to attach the car seat straps.

A6 Interior Quality

It may be getting up there in years, but this generation of the A6 has lost none of its interior luster. The cabin is among the nicest in the class, and the materials are top-notch.

A6 Cargo Space

The Audi A6 has a smaller trunk than some other midsize cars, though it's about average for the class overall. It has just over 14 cubic feet of space, though the rear seats fold down to provide extra room if you need it. The liftover height is low, but the trunk opening is a bit narrow. Despite the unimpressive trunk, the A6 still has enough room for about 10 shopping bags or pieces of carry-on luggage.

A6 Infotainment, Bluetooth, and Navigation

The A6’s standard features include a sunroof, satellite radio, Bluetooth, navigation, and the MMI infotainment system with an 8.3-inch display screen. Available features include quad-zone automatic climate control, a Bose audio system, a Bang & Olufsen audio system, a touchpad with handwriting recognition, Android Auto, and Apple CarPlay.

The MMI system is intuitive and responsive. So much so, that some users think it’s easier to use than the available Apple CarPlay and Android Auto connectivity systems. The available audio systems deliver outstanding sound quality.

A6 Performance

A6 Engine: 4, 6, or 8 Cylinders?

The base A6 comes with a turbocharged four-cylinder engine that puts out just over 250 horsepower. It moves this midsize sedan easily, but there are larger engine choices for more power-hungry buyers. Higher trims feature a 340-horsepower supercharged V6, and the performance-oriented S6 comes with a turbocharged V8. These larger engines will throw you back in your seat while accelerating and have power to spare even during high-energy driving maneuvers.

A6 Gas Mileage: Reliable MPG Ratings

The Audi A6 gets better fuel economy ratings than many of its classmates, earning estimates of 25 mpg in the city and 34 mpg on the highway with the base engine. It does require premium gasoline, but so do many other luxury cars.

A6 Ride and Handling: Bust a Move

The A6 has an athletic feel and plenty of agility to let you enjoy driving on curvy roads. Front-wheel drive is standard, but the available Quattro all-wheel-drive system provides better road grip and is the preferred setup. The A6 generally rides smoothly, but it will jolt you occasionally over rough pavement.

Which Audi A6 Model Is Right for Me?

The Audi A6 has several trims to choose from, and like many luxury cars, all are well-equipped. Nobody would blame you for sticking with the base trim, particularly since the 2018 model has more standard features than in previous years. The A6 Premium Plus is worth a look, though, because it has more available features and its starting price is only slightly more.

There’s really no need to go higher than the Premium Plus unless you want the V8 engine, which packs an outstanding punch but will cost you an additional $10,000 at least. The V8 is only available in the S6 trims.

Audi A6 Premium

Despite the name, the A6 Premium is actually the base trim. It has a starting price of $49,700 and comes standard with front-wheel drive and a turbo-four engine. You can add all-wheel drive for $2,200, or you can add the supercharged V6 engine and all-wheel drive for $6,800 (FWD models aren’t available with the V6). You can also add heated seats and a heated steering wheel for around $500.

Audi A6 Premium Plus

The A6 Premium Plus starts at $51,900. FWD and the turbo-four are standard, and AWD and the V6 are available. In addition to the Premium’s features, the Premium Plus comes with quad-zone automatic climate control, a Bose audio system, and blind spot monitoring. The Driver Assistance package adds helpful features like adaptive cruise control, lane keep assist, forward collision warning, and automatic emergency braking, but it costs more than $2,500.

Audi A6 Prestige

The A6 Prestige has a starting price of $61,400. The supercharged V6 is the standard engine in this trim, and all-wheel drive is standard as well. In addition to the lower trims’ features, the Prestige comes with a power trunk, ventilated front seats, and a head-up display. For about $2,500, you can add the Night Vision Assistant. You can upgrade to the Bang & Olufsen audio system, but that will set you back nearly $5,000. The Comfort Seating package costs around $3,400 and adds contoured, massaging front seats.

Audi S6 Premium Plus

The Audi S6 Premium Plus is the high-performance variant of the A6, and it starts at $71,900. All S6 models come standard with all-wheel drive and a turbocharged V8 engine. Its features list is nearly identical to the A6 Premium Plus’, though the S6 edition adds a few sport-oriented touches like larger brakes and a sport-tuned suspension.

Audi S6 Prestige

The S6 Prestige is the highest trim, with a starting price of $74,400. Like the Premium Plus, the S6 Prestige’s features list closely mirrors the A6 Prestige’s, with the exception of a few performance upgrades.

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

  • "The 2018 Audi A6 should be suffering from diminished appeal. After all, it's been kicking around without a full redesign for six model years now while its prime competitors have been completely redone in the past year. It's old news. Well, that might be true in terms of attracting attention, but in the end, the A6's appeal has in fact diminished little. This well-rounded luxury sedan continues to deliver exactly what shoppers in this segment are seeking: room, features, luxury and performance in abundance." -- Edmunds
  • "The 2018 A6 … splits the comfort/performance balance of the Mercedes-Benz E-Class and BMW 5 Series, all while imparting its own personality. Don't let the A6's understated attitude fool you: Underneath that contemporary skin is an executive sedan that's rewarding to drive and technologically advanced. … In addition to its German rivals, the A6 faces competition ranging from the Lexus GS and Jaguar XF to the Cadillac CT6. While the A6 may fly lower on the radar, it merits a spot on yours." -- Kelley Blue Book
  • "The … Audi A6 is the perfect example of a midsize executive sedan, blending elements of luxury, sport and high style." -- Autotrader (2016)
