Overview & Reviews
Luxury-car shoppers who love value have long cheered the Audi A6. And in true Audi fashion, the midsize A6 gives you a lot for a very competitive price. One of the A6's primary strengths is its deluxe cabin. Materials are first-rate, and the overall design is nothing short of class-leading. Its winter-weather capability is another plus, as most A6s on dealer lots, like other Audis, have all-wheel drive.
But the car's most compelling asset concerns value. In terms of overall quality and performance, the Audi A6 is typically equal to or even better than its luxury sedan rivals, yet it typically costs thousands less. A used A6 represents an even more affordable proposition, though these older examples lack the athleticism of their more contemporary rivals. The latest A6 benefits further still from enhanced performance and increased driver engagement, making it a top choice in the segment.
Current Audi A6
Powering the base Audi A6 is a turbocharged 2.0-liter inline-4 (2.0T) that produces 220 horsepower and 258 pound-feet of torque. Other engine choices include a supercharged 3.0-liter V6 (3.0T) with 310 hp and 325 lb-ft of torque, and a 3.0-liter turbodiesel (TDI) that cranks out 240 hp and 428 lb-ft of torque. Front-wheel drive and a continuously variable automatic transmission (CVT) are standard on the 2.0T. Standard with the other engines, and optional on the 2.0T, is an eight-speed automatic coupled to all-wheel drive. Fuel economy across the board is quite favorable when compared to competing sedans.
Trim levels start with the Premium (2.0T only) and move up through Premium Plus (2.0T, 3.0T and TDI) and Prestige (3.0T and TDI). Standard feature highlights of the Premium include a sunroof, tri-zone automatic climate control, leather upholstery and heated front seats. Premium Plus trims add larger wheels, xenon headlights, parking sensors, keyless ignition and entry, upgraded audio, a navigation system and an in-car Internet connection. The Prestige boasts adaptive headlights, unique exterior accents, quad-zone climate control, ventilated front seats and a Bose sound system. Options depend on trim levels and include LED headlights, a sport-tuned suspension, a top-view camera system, a head-up display, various electronic driving/safety aides, and a Bang & Olufsen sound system.
In reviews, we rank the current Audi A6 highly for its engaging driving dynamics, excellent interior, long list of features and impressive combination of performance and fuel efficiency. Drivers with a penchant for winding roads will certainly appreciate the A6's tenacious grip on the pavement and well-balanced weight distribution, while others will likely enjoy the quiet and attractive cabin that is well stocked with intuitive high-tech wizardry. Whereas previous A6 generations played second fiddle to their Mercedes and BMW rivals, this latest version has no problem challenging them for first chair.
Used Audi A6 Models
The current A6 debuted for 2012 and represents the fourth generation in the car's lineage. Adopting the latest Audi design language, the A6 is distinctive for its large trapezoidal grille and more angular headlights. It is also notable for improvements in regard to performance, making it the go-to choice as a "driver's car." The next year brought automatic engine stop-start for the V6, available all-wheel-drive for the 2.0-liter engine and the available top-view camera system. Apart from the 2.0T having slightly less power (211 hp versus 220 hp), the unavailability of the TDI and a slight shuffling of trim levels, these latter A6s are similar to the current version.
The third-generation Audi A6 ran from the 2005 to the 2011 model year. Overall, the third-generation car represented an admirable mix of attention-getting style, entertaining driving dynamics and opulent furnishings. A wagon body style, known as the Avant, was offered alongside the sedan.
In the third generation's final year of production, three engines were offered: a 265-horsepower V6 (3.2), a 300-hp supercharged V6 (3.0T) and a 350-hp V8 (4.2). The 3.2 front-wheel-drive sedan had a CVT, while all other A6s came with a six-speed automatic transmission and all-wheel drive. The A6 Avant was only available with the 3.0T engine, AWD and the automatic.
Throughout the production run, trim levels were generally structured around engine selections. For the most part, three trims were offered: base 3.2 Premium, midlevel 3.0T Premium Quattro and top-of-the-line 4.2 Prestige Quattro. Wagons were available only in the 3.0T Premium Quattro trim. Standard features were as generous as any luxury car for the time, with navigation standard for all and the upper trims coming with heated seats. Meanwhile, Audi's easy-to-use Multi Media Interface (MMI) system made controlling audio, navigation and Bluetooth functions easy with clear and logical menus.
Those considering third-gen models should keep in mind that the base V6 made only 255 hp from 2005-'09 (later increased to 265 hp). Also, the supercharged V6 (3.0T) wasn't available from 2005-'08, while the car's V8 produced only 335 hp prior to 2007, when output was bumped to 350 hp. In terms of features, the A6 has stayed mostly unchanged, though trim packages and options were also simplified for '09, and the MMI electronics interface and navigation system were upgraded for 2010.
In reviews, we've found the engines smooth and refined. The base V6's acceleration is certainly passable, but our choice would be the 3.0T thanks to its broad range of torque and relative fuel efficiency. In fact, we've found this engine provided quicker acceleration than the V8. The A6 rode comfortably on the highway, and while it wasn't the most athletic car in its class, our editors applauded its predictable, confident feel around corners.
The second-generation A6 sedan arrived on the market in 1998 and benefited from a ground-up redesign; an all-new version of the Avant wagon debuted the following year. This was the first Audi A6 to ride on a stretched version of the highly regarded A4 platform.
For the first two years, only a naturally aspirated V6 was available, but in 2000, Audi added a spirited twin-turbocharged V6 and a torque-rich V8 to the sedan lineup. Given that acceleration tended to be sluggish with the base V6, particularly on the hefty A6 Avant wagon, Audi began offering a more powerful 3.0-liter six-cylinder in 2002. Transmission choices included a five-speed automatic and a CVT (which was introduced in 2002). In reviews, we praised the heavenly cabin and all-wheel-drive utility offered by the second-generation A6, and panned its somewhat nonlinear steering. Overall, it represents a solid choice for used-car shoppers.
The original Audi A6 came to market in 1995 as a lightly revised version of the old Audi 100 sedan and wagon. Although prices on used A6 models from this era are convincingly low, consumers should be aware that only one engine -- a 172-hp V6 -- is available on these cars. With the lightest A6 sedan weighing in at 3,400 pounds, acceleration is modest at best. However, much like newer Audis, this A6 was nicely appointed and offered a choice of front-wheel drive or Quattro all-wheel drive.

Most Luxurious 98,000 mile life disposable car - 2006 Audi A6
By Steven - January 14 - 6:01 pm
Ok, well we loved this car, then hate this car, then love this car, and so on... It all comes down to reasonable and prudent reliability and quality of materials. This was a 24000 mile pre-owned Audi certified car we purchased. Driven lightly for the last 5-6 years, garage kept 1/2-2/3 of the time owned. What's good? Performance, feel, and overall car experience were favorable. Fuel economy is outstanding, especially highway. Car has generally been trouble free, or so I thought (see What's Bad). What's Bad? Where to start. 1) Service intervals - we have had this into Audi every 10K per suggested and every time we leave with no less than a $400 bill gone for what I would have normally thought was a Jiffy Lube type $65 event. They ALWAYS find something wrong that needs to be fixed or replaced, or updated - and being a good Audi owner I comply since I want my Audi to be in top shape all the time. 2) Absolutely $%## poor quality of materials on interior knobs, dials, and trim. Just google it and you will see lots of people with delaminated interior trim. Audi chooses to turn the other way though and does not recall this to fix an obvious mfg defect. Its a calculated risk for them I assume thinking not enough care - I do and on this alone, I will never buy Audi again. I tried to sell my car (which is otherwise in great shape) and everyone was turned off by paint peeling off of the various knobs and dials. 3) Power Steering - Developed a leak at 65K miles. Too expensive to repair on my quickly depreciating car - no return on investment there, so just keep adding the $30/pint Audi fluid as need be. 4) Oil Use - uses about 1 US Quart of $8 synthetic oil every 4K miles. No matter what they say, this seems excessive. My Ford Explorer had 200K and used 1/3 of that. 5) Technology - Even in 2006, simple things like AUX jacks should be available. There is no way to connect a device other than Radio Frequency Module - which suck. My 2002 Corolla was better than that. 6) Navigation is ok, not great. Its so outdated and Audi wants you to pay $300+ for their map update CDs....residual income for them I guess. 7) Battery - The $180 battery that goes with this only makes it about 12-14 months then dies. Get a good one with a warranty since you will be using it A LOT. 8) And now for the 95,000 interval (I had to wait to 98,000...shame on me). Remember that the car has been factory serviced every 10K since 24K miles.... 8a) Windshield washer pump was shorted out $400 - had to fix this since its a safety item. 8b) windshield washer blades - there are no auto store or aftermarklets available. Audi must provide these @ $60. 8c) Oil and filter change @ $400. Up to $800 now. 8d) take a guess...bad battery $180 (I declined since mine is Autozone and under warranty). 8e) Motor mounts are bad (huh?) - $1300 - I declined. 8f) Adaptive headlight sensor error - must remove front end to check it $1200 (for a light that is still shining? LOL) - I declined. 8g) Rear brake light error - tech tried to check this but the lens covers were too brittle. New ones cost $1200 - again LOL - I declined. 8h) Front end bushings need replaced - $1800 - I declined. 8i) Oil leak noticed around timing and valve cover - $1500 - I declined. I stop them here. This $6,500 car is way past its service life at 98,000 miles. Didn't even make it to 100K - wow for a $65K automobile. I share my experience with the first person I see who I knew had a A3 with 50,000 miles on it. They just traded theirs in after their service call quoted them thousands of dollars in very similar repairs and failures. Different dealership, different auto groups so no suspicion there. I assume its just a fact that an Audi is disposable ($0 value) after 8-10 years or 50-90K miles. Well, I hear scrap metal is $3/100 pounds so there is that.....
Great driver's car - 2014 Audi A6
By Dan - January 7 - 5:07 am
We love to drive this car. It's a rocket, getting 40 to 42 MPG on the highway. Beautiful interor, quiet.
2000 Audi A6 quattro 2.7t My green alligator - 2000 Audi A6
By Richard Tanguay - December 27 - 7:29 pm
Like many others have said, expensive car to buy, will go anywhere in the snow, lots of power with the twin turbos, but after about 60,000 miles lots of leaks and sensor problems. Spent about equal time driving and being in the service station. Vacuum leaks, cam shaft seal leaks, valve cover leaks, axle leaks. Just about every week, something new comes up to fix and the repair bills were about $4,000 per year. Figured I better get rid of it before the turbos, engine, or transmission need replacing because those thing would cost me more than the car was valued at. I did keep the car for about 16 years, but if I had to do it over again I wouldn't by an Audi (way overpriced), or if I did, I would sell it at about 60,000 miles. They do not hold their value well. On a positive note, one of the best things about the Audi was after 16 years, there was no rust anywhere on the vehicle. Audi did an excellent job with metal finishing and plastic protecting guards underneath the vehicle to limit corrosion on these New England salted roads. In closing, my personal experience with the A6 is that it just keeps eating away at my wallet, my green alligator. Never another Audi for me.
Still a great car at 105K - 2008 Audi A6
By Steven Woods - December 17 - 3:37 pm
Update to my earlier review. Now I have over 105k miles on this car that I purchased new. It goes through brakes but it has otherwise been faultless. Still love driving it. Same great ride, no rattles and no issues. Recently had to add some coolant, but other than that, just routine oil changes.
Hurts to sell this one... - 2006 Audi A6
By A6 Guy - November 29 - 7:20 am
Just traded in my 2006 A6 Quattro sedan 3.2 S-line with 117,500 miles for a 2016 Prestige A6 3.0 and while the new model is fantastic, I hate stepping away from my 2006. This was my first Audi and the most enjoyable car I have ever owned. Bought as CPO with 30k. The 2006 was quick and handled like on rails. Quattro system is awesome in WI winters (especially equipped with Blizzak snow tires). I had a few warranty issues before 50k (covered by Audi) and little to none since. I maintained my car well and it treated me right. Local independent shop handled all needed work. I'm am only selling for fear of costly repairs down the road which if I could predict to be reasonable, I'd keep it. Lastly, the Bose surround system is the best factory car audio I have ever heard. The misano red turns heads and many folks still think the 06 is a newer car. If you don't get hit with reliability costs, the 2006 is a GREAT value.
Brakes - 2014 Audi A6
By Phil - October 23 - 4:57 pm
i lease a 2014 Audi a6. the car sits in my heated garage from December to April. i leased the car in May and during the first winter the brake pads froze to the rotors. When i tried to move the car in the Spring i had to gun the motor to brake them loose. the audi dealership said the only solution was to replace the rotors and i only had 13,000 miles. i had the rotors turned at a local shop and this lasted for 4 months before the rotors were again corroded. At this point i no choice but to replace the rotors and Audi was no help. they said it was normal wear and tear. The dealership was very helpful in covering some of the costs but Audi covered nothing. Thin twice about a new Audi
Best in class - 2014 Audi A6
By John - September 21 - 10:50 pm
Phenomenal mid-size luxury car! All of the benefits of the old, large V8 engines that used to be in the luxury cars, without any drawbacks. Not only do I get smooth power basically anywhere in the powerband, but I get exceptional fuel economy if I am cruising on the highway. The supercharger allows for the immediacy in power, which is essential for drama-free passing on the highway, and it also allows for quiet, efficient cruising. With a light foot, I have had the car exceed 38 mpg, with normal highway cruising returning ~30 mpg. I mean seriously, it feels like a crime having both power and efficiency. Everything else is as expected: quiet, comfortable cabin with class-leading technology, layout and materials used. The screen is beautiful, with NVIDIA graphics allowing for beautiful map rendering, the Bose sound system is rich, and the MMI is fantastic once you get used to it. I am techy so it took me about 1 day to learn the system while driving around, but I feel as though almost everything makes sense in terms of layout and ergonomics. The ride is not as supple as some of ultra-luxury cars with air-suspension, but those cars are no fun to drive. This is the perfect compromise. I bought the car used with ~5k miles on the odometer, which not only took a few thousand off the price, but more importantly gave me the piece of mind of a 5 year 100,000 mile warranty! My only question is how much less power does the 2.0T have? Because for day-to-day commuting, you don't even get into the power in this car. Yes, it's nice to have the power to pass 98% of cars I see on the highway, but at the same time, 90% of my driving is done with efficiency in mind.
Beautiful body, tough on tires, - 2014 Audi A6
By Audi Reviewer - July 17 - 8:17 pm
Owned my 2014 A6 TDI Premium+ for 18 months and have driven it 30,000 miles. Pros: THE best looking styling of all European/Japanese/American mid-size luxury sedans, hands down. Love the TDI diesel--44+mpg combined, quicker than a bullet, quiet engine (see the one major con on this engine below). Road handling is superb and this car is a blast to drive on a curvy highway. Cons--On the other hand...not the most comfy to drive on long trips and I have taken this car cross country. I get it's a sports sedan but after a while the lack of expected comfort starts to wear on you (esp. on a $60,000+ car). Tires--I have 30,000 miles on them, I don't drive hard, but the dealer told me I have about 10,000 miles left on them. What? 40,000 miles on a set of Dunlops? Biggest beef--as the tread wears down the noise these tires make is unbearably loud. Last issue-- Audi sends me a letter letting me know my TDI diesel engine was engineered to run on UP TO 5% biodiesel. Unfortunately I live in a state that mandates the sale of 20% biodiesel in the warmer months. Nice. Wish my dealer would have mentioned that to me when I bought the car. Audi goes on to state in the letter to me that in any event, they WILL honor any warranty issues arising out of the use of this biodiesel. As one who usually "buys them and drives them forever", I don't think I want to own this car after the warranty expires. I love this car but doubtful I will buy another diesel engine as long as I live in this state. I realize this is not Audi's problem but hopefully they are working on this biodiesel issue.
German "cruise" missile - 2012 Audi A6
By GW - July 15 - 6:19 pm
I was fortunate enough to find a rare very loaded A6 just off lease. Previous owner had Audi Care so all the services were done-key to a used Audi. Car has Sport Package, night vision, HUD, Prestige, OEM 20" wheels, Havana black-incredibly cool color upon close inspection- nougat interior heated cooled, LED headlights and interior, adaptive cruise, Nav, becomes WIFI hotspot, on and on. Huge trunk, fold down rear seats-tons of cargo spaceDoes not have B&O sound, my traded S4 did. Have to say I find nothing to fault with the Bose surround to take nothing away from B&O both are great (Bose$6K+ additional cost on this car. MSRP was $67K. Bought for $34.5K with 49K miles. Car presents as near new. 8 speed auto is a pleasant upgrade from the 7 speed in S4. DSG was great but, this tranny shifts like silk and does not require costly DSG fluid replacement intervals. Plus you still get the paddles if you want to use them. Mileage is a solid 28-29 highway. 8th gear makes the difference. S4 struggled to get 23 on highway. Pick up is robust when needed but, super smooth and comfortable unless you get into the right pedal. Awesome car. This is my 4th Audi. I highly recommend the Prestige package, it costs more but is in my opinion clearly worth it. Great car.
100K and going strong - 2008 Audi A6
By docwoods - June 22 - 11:56 am
This is the third review from me on this car. Just turned over 100,000 miles without any significant issues. I am the original owner and just follow routine maintenance. It is still solid, quiet and a great performer. This is the best car that I have owned. Looking to keep it at least 10 years.
