Model Overview:

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.

  • Once you go QUATTRO you cant go back! - 2004 Audi A6
    By -

    This is the best piece of man made machine I have ever driven. I drove Infiniti G35s and Nissan 350Z and then had two hondas and one gm. Of all those cars, I can say this is in its own category and nothing comes to close to the performance and comfort and style and OH YOU HAVE A NICE CAR comments. MY next car will be an A8L but I will enjoy every bit of my A6. Every time I start the engine and hear the muffler noise (modified) I just cant wait to hit on the gas pedal and accelerate. The feel is way beyond anything I can ever own and AFFORD to own. 20k$

  • Terrific CPO purchase - 2006 Audi A6
    By -

    I had finally outgrown my e36 m3 and decided to get a more austere sedan. I shopped Infiniti, BMW and Audi. I picked up a CPO 2006 A6 and couldnt be happier with it. The car drives wonderfully, although the V8 is a little thirsty if you keep your foot in it. I expected that though. The car is built very solid, and offers 90% of the 5er performance, but with a bit more comfortable ride. I have non-sport suspension btw, and look to change that at some point, mainly to minimize the 3" wheel gap (Toyota?). Otherwise, the car is gorgeous, and I look forward to keeping it for quite awhile. I think an A6 is a terrific CPO purchase, the extended warranty could come in handy (hopefully not).

  • Fun While It Lasted - 2002 Audi A6
    By -

    Loved the looks and performance of this car - both inside and out - but now shopping for a new car at only 90,000 miles. Extremely disappointed that this car didnt live up to the expected 200K miles. As soon as the extended warranty was up, the problems started, multiplied and some unable to fix. Inept and outrageously expensive dealer repairs and other folks just dont like working on Audis, will not take me down this path again - too bad for they have some beautiful new cars that I would love to own like the A5. However, this experience has totally soured me on Audi and taking a new direction.

  • fun - 2003 Audi A6
    By -

    fun to drive, especially in sport mode, had water leakage problem (battery holder overflow into passenger footwell ruining a $1700 transmission control cpu, catalytic converter failure, CV boots needed replacing, easily breakable cupholders quattro goes through tires, not as reliable as a japanese sedan but way more fun to drive

  • Super car - 2001 Audi A6
    By -

    This is our third Audi, was impressed with the first two, (67 and 71) so I took the chance to purchase this one off Ebay for my wife. Weve put 35,000 miles on it in the last 4 years and other than regular maintenance, we have had only the alternator fail. Average fuel economy 27 mpg in the summer and 23.5 mpg in the snow. Best fuel economy on a trip so far was 32.1 mpg. It is a little hard on tires (or is that me?) The turbos really help with the high altitude here. With all the driving we do on gravel and dirt roads, not a single squeak or rattle. Super car.

  • Snow Monster - Love It - 2010 Audi A6
    By -

    Ive had this car 3 months, and love it. Comfortable, handles great, and fun to drive. This car is a monster in the snow. Nothing holds it back in the white stuff. I test drove all the usual suspects, and picked the winner.

  • Great looking and thats about it - 2001 Audi A6
    By -

    Purchased the car used with less then 30k miles. Had all the bells and whistles. Great looking car but no reliability in this vehicle. Before having 5ok miles timing belt had to be replaced and water pump went out. Great looking car but not up to par against Infiniti, BMW or Lexus...i will never buy another Audi again!

  • Love my Audi 2.7T - 2002 Audi A6
    By -

    I have replaced CV boot, tie rod, brake pads and rotors, and expect to keep spending money on it. my friend is a good mechanic so he helps me out i just have to pay for parts. but if youre looking for an economy car, get a Honda/Nissan. If youre looking for something between Luxury and Sportscar, get an Audi. its too heavy to be sporty but that makes it perfect for cruising and a little smoother ride. its not as big as the A8...but is roomy enough to be considered a luxury car. I would recommend this car ...to someone who thinks they might like Audis ...or who like VW. Just do ur research and make sure you dont find something thats been ragged on or wrecked. :)

  • Plagued with problems - 2008 Audi A6
    By -

    My A6 continues to be plagued with problems. Spent 10 days in the shop over thanksgiving. Oil seals on all 6 cylinders had to be replaced. A major job on a car with only 12k miles. The carbon buildup issue which was initially attributed to a computer reprogram turned out to be failing seals. I also mentioned a rattle/squeak from the front left suspension dealer greased the suspension per Audi directives but to no avail. Car was in the shop for 1 week. Now it turns out that it may be a bushing problem (a known issue amongst Audis) and I am being asked to take the car back again. BTW - JDPower only gives the A6 a 6 rating which is on the cusp of below average.

  • Perfection - 2007 Audi A6
    By -

    This is my favorite car yet. I have had other German cars and they dont compare. I have put 10,000 miles on my Audi and not a single problem. The car handles really well in the rain and is perfect for defensive driving with all these other crazy Florida drivers. It is beautiful on the outside and ultimate luxury on the inside. I even left my purse with my cell in the trunk and I was able to still make calls with the built-in bluetooth. I am so satisfied with this car I want to keep it another 3 years and continue with Audi.
