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.

Annoying quirks - 2008 Audi A6
By chicagotiger - March 29 - 8:58 pmOur Audi for the most part has been fabulous. However in the 2 years weve owned the car, weve only put 7,500 on it and our check engine light has come on 3 times. Perhaps its dishonest gas pumps, but we always use the premium gas. Its very annoying to have to take it in for service, get no real details, a couple of dings on the car and not even a car wash at our local dealership. Even though its been a nice ride for the most part, Id like to get rid of it before something major blows.

Excellent vehicle - 1999 Audi A6
By Pitt05 - March 26 - 10:26 pmThis is my second 1999 Audi A6. Both cars have proven to be very durable. Each car had the same minor issues, ie: broken mirror adjust switch, et cetera. (easy fixes) The build quality is top level, classic styling , decent power, and unstoppable in any weather. I have done most of the things people complain about in their reviews, but they dont seem to understand its routine maintenance, control arms, timing belts, and others. That being said, if you maintain a car like this properly, it will last a very long time. Owning a high end German car is a commitment (but ultimately very rewarding) , if your not willing to pay, get a generic Japanese luxury car, what a tool youll look.

Short review after 1400 miles- A6 - 2010 Audi A6
By Mattsam - March 20 - 7:30 pmI purchased the 2010 Audi A6 3.0 supercharged early this year. WOW what a car. Im an Acura guy and looked hard at a RL, the ZDX, and another MDX (would have been my third) All are great cars with only the MDX considerably less expensive. They just didnt thrill me. I was leasing my first company vehicle and I have owned/driven many of the premium brands. I was always drawn to the Audi, I hardly see one on the road. The ride is plush, the gadgets are over the top cool, and the 3.0 supercharged engine is top notch. Its been in the shop once already for check engine (dirt in a sensor) but I dont care. Every time I drive it Im smiling ear to ear!

High Maintenance Beauty - 2001 Audi A6
By SeattleQD - March 18 - 12:57 amI love my Avant wagon. It is beautiful driving and looking car but more expensive than ever to maintain. I purchased the car with 57,000 miles on it and took excellent care of it. I even used premium Mobile oil. The catalytic converter went our at 70,000. I have paid out $5,000.00 in repair costs not including the converter which I never had replaced. If you have money to carry the cost of ownership go for it! The driving experience is like none other.

Pleasant Surprise - 1999 Audi A6
By Bob - March 16 - 8:30 pmLots of bang for the buck in mechanics, body, interior and creature comforts - and they all have worked with no trouble. No exterior noise at any speed, some gear noise at 35-45, handles precisely, always starts first time. Auto leveler works for any weight - up to cement bags and block filling rear. Designed and works for smooth driving gas efficiency is great for heavy car when alert to traffic lights and with light foot on brake and gas pedals. Cruises without effort, and rpm to spare for passing. Roof rack needs better connectors/tie-down points + paint protection. Headlight washers/rear wiper and defroster all still work well. Stable in ice/snow/slush/mud. Wife loves heated seats!

performance enhanced luxury - 2010 Audi A6
By ed svoboda - March 15 - 12:15 amQuite simply a pleasure to drive. Fit and finish very tight. It begs to be pushed. The supercharged 3.0T kicks at 2000 rpm and rips to 6500 plus.

Secrets to owning an Audi - 1998 Audi A6
By webegeek - March 12 - 7:48 pmOkay, this was my dads car. He bought it after Id bought an A4. Two secrets: One, if you drive a lot of miles each year, they dont last. Two, find a good independent mechanic as soon as the warranty period is over. My A4 was costing me 2k every time I needed an oil change and I finally sold it. My dads A6 did better, he doesnt drive much and took it to a local place to have work done. And Ive lost count how many times hes lost the front lower spoiler on curb stops.

Not happy! - 2008 Audi A6
By Robert - March 11 - 7:58 pmWell have had my a6 for just 2 yrs now and 40,000 miles and the problems just keep on coming. First was the seat controls separating from the seat at 17,000 and not covered under warranty charged $40 to tighten bolt. Next was the xenon headlight going on and off, dealer said it was what they do when they are about to go bad $350. Then car started to run rough and engine light on told computer issue but that did not fix it. Then back to shop to find out it was carbon build up. Major engine work, fixed under warranty this time otherwise over $1,000 to fix. Dealer said that its because the gas today is not high enough octane to work with audis new engine design. Whats next? My last Audi.
