Overview & Reviews

The flagship Audi A8 is a full-size luxury sedan meant to appeal to wealthy consumers looking for maximum luxury and space. Although competing models from the premium German and Japanese marques may sell in greater numbers, the A8 does possess a distinct advantage because of its aluminum frame and body panels. Significantly lighter than a traditional steel structure, the Audi Space Frame (ASF), as it's called, helps offset the weight of the car's Quattro all-wheel-drive system; the A8's competitors are primarily rear-wheel drive.

Thanks to Quattro, winter weather capability is one of the Audi A8's strengths. Luxurious accommodations are another, particularly with the last couple of generations. As with other Audis, understated luxury and cutting-edge electronics combine to form an experience that delivers refinement in abundance. Though it's sometimes overlooked, the A8 is a fine choice for a luxury flagship.

Current Audi A8
The Audi A8 is a full-size luxury sedan available in standard and long-wheelbase ("L") forms. Even with standard all-wheel drive (AWD), the A8 still weighs less than most of its rear-wheel-drive rivals, let alone those fitted with optional AWD. The A8's AWD system has a rear-biased power split, which helps to provide a sportier feel akin to a rear-drive performance sedan.

There are six trim levels: 3.0T, L 3.0T, L 3.0 TDI, 4.0T, L 4.0T and L W12. The 3.0T trims have a supercharged 3.0-liter V6 with 333 horsepower and 325 pound-feet of torque. Like all A8 engines, it runs through an eight-speed automatic transmission. The 4.0T trims have a turbocharged 4.0-liter V8 that makes 420 hp and 444 lb-ft. The W12 features a 6.3-liter 12-cylinder engine that cranks out 500 hp and 463 lb-ft.  In addition to these gas-fueled powerhouses, there is the 3.0 TDI, a 3.0-liter turbodiesel V6 rated at 240 hp and 406 lb-ft. Regardless of engine choice, acceleration is swift, with the 0-60-mph sprint ranging from around 4.2 seconds to 6.3. Fuel economy is also notable, with the TDI in particular rated at an impressive 28 mpg combined.

Of course the A8 comes loaded with all the latest high-tech features. Highlights include a dynamic steering system that can intervene with automatic countersteering in a slide, adaptive cruise control with stop-and-go capability, automatic emergency braking, and night vision with thermal imaging and pedestrian detection. Audi's MMI electronics interface features an additional touchpad interface that reads fingertip gestures as letters and commands. Google Earth mapping for the navigation system is another A8 exclusive.

Beyond the sumptuous cabin, which features front and rear seats that can be adjusted in a multitude of ways, there's also the big sedan's impressive ride and handling characteristics. The ride is comfortable without excessive float over bumps. When pressed on a curvy road, the A8 proves surprisingly agile, with nicely weighted steering. Rear seat room is ample in the regular-wheelbase model, while the A8 L provides more than enough legroom for a pair of 6-footers.

The A8 undoubtedly lacks the name recognition and styling flair of its fellow Germans, but don't let that stop you from giving it strong consideration. With its roomy, best-in-class cabin and excellent driving dynamics, this luxury sedan shines as one of the strongest picks in its segment.

Used Audi A8 Models
The current A8 represents the third generation in the model's history, debuting in 2011. In that inaugural year, the sole engine was a 4.2-liter V8 engine with 372 hp and 328 lb-ft of torque. The following year brought the 6.3-liter W12. For 2013, the 4.2-liter was dropped, while both the supercharged V6 and turbocharged V8 seen in the current lineup debuted. Apart from lacking the TDI engine option and some minor differences in standard and optional equipment, these latter A8s are otherwise essentially identical to today's version.

The previous, second-generation Audi A8 was sold from 2004-'10. Relative to its predecessor, this generation offered a lighter chassis and a more muscular V8, along with lots of comfort, safety and suspension upgrades. This A8 was offered in both standard-wheelbase (A8) and long-wheelbase (A8 L) versions. The base engine was a 4.2-liter V8 that generated 335 hp and later rose to 350 hp for 2007. A six-speed automatic transmission and all-wheel drive were standard. From 2005-'09, there was an A8 L W12 model that featured a 6.0-liter 12-cylinder engine that produced 450 hp.

Changes were light during this generation. There were slight styling alterations for '08, while the equipment list was bolstered nearly every model year. Regardless of which year you may be considering here, cabin furnishings were superb and the MMI interface made accessing the car's numerous audio, climate and navigation functions fairly easy. This A8 was often overlooked by luxury sedan shoppers, but we always found it to be a great alternative and certainly equal to other flagships in terms of luxury, performance and craftsmanship.

The first-generation Audi A8 was offered from 1997-2003. Although it was one of the most technologically advanced cars on the market by virtue of its aluminum frame, it never had its successor's flair for style or performance. Understated in its adornments inside and out, the original A8 failed to deliver the over-the-top ambience that's so important for high-dollar luxury sedans sold in the United States. However, if you like the idea of owning a discreet luxury car, you can buy a used A8 for considerably less than you'd pay for a used BMW 7 Series or Mercedes-Benz S-Class.

Early Audi A8s were offered only with a 113-inch wheelbase, which meant that their backseats were cramped compared to the other full-size luxury sedans. The longer and roomier A8 L arrived for the 2000 model year and would be our pick if you're planning to carry adults in back. Most first-generation A8s were sold with a 4.2-liter V8 and Quattro all-wheel drive. Thusly equipped, the A8 was one of the quickest large luxury sedans of its day, though the V8 was deficient in off-the-line torque. It was a comfortable car but not a particularly entertaining one due to overly soft suspension tuning. Audi also offered a less expensive front-wheel-drive model from 1997-'99. This rare A8 had a small 3.7-liter V8 and a modest 8.3-second 0-60 time.

  Auto Mags are missing the boat - 2013 Audi A8
  By baygasauto - January 23 - 10:29 pm

  WOW!!! Automobile, Road and Track, Car and Driver..youre all missing something special by ignoring this beast. My previous were a GS400, BMW 545i, Panamera 4s (8cyl). I swear this car out accelerates the Porsche and handles better than the Lexus or Beemer w/sport pkg.. This Audi accelerates so effortlessly and uneventful it almost scares me. A locomotive that Edmunds claims does 0-60mph on 4.2. After 2500 miles, Im finally gettin the guts to push it around corners. It sticks like glue. However youre so relaxed driving this vehicle it seems a shame to throw it around like the Porsche. Cmon car mags, spread the word. This beast is something very special.

  40k-110k review - 2007 Audi A8
  By boyracer3 - January 20 - 5:34 pm

  Bought a preowned A8L 07 a couple of years ago. Have put 70K on car since. It has been remarkably reliable. The build quality is excellent. I dont get the gas mileage it promised unless driving over 70. I have all service done at dealership, and have been very surprised at the low cost of maintenance, and the quality of service. Had a new A4 in 07, hated it, swore Id never buy Audi again, got bad service. Bought the 8 because I needed big and 4WD. Expected many of the same problems I had with the 4, but it is a much better car. And I think Audi is a much better car maker and has made huge efforts to improve customer satisfaction.

  2013 Audi A8 short wheel base - 2013 Audi A8
  By mancaver - December 26 - 5:26 pm

  I have only had the car for two weeks, so I cant accurately comment on the reliability---but all other aspects I rated as execllent, so I expect the relaibiilty to be the same. Anyway, I owned an Audi A4 which was very reliable. I understand Im still on my "honeymoon" with this car, but so far it is great---I have owned: MB E320 and C280, Acura Legend and TLS, Lexus ES330, BMW 530i and 535i, Mazda Millenia and RX7, Honda Civic and Accord, and even a Triumph TR6---of course, any new car will have features unheard of a few years ago---but the A8 is everything the (just about unanimous) positive revews describe.

  The best Luxury Car money can buy!!! - 2012 Audi A8
  By donnie13 - March 25 - 7:03 am

  I had a 2006 750LI and loved this car. Traded for a 2009 Audi A8L and while was a great car, didnt have enough pizazz. Traded it for a 2010 Mercedes S-Class. Was a good car but too soft. Felt floaty. Bought a 2011 Eguus, while a good car, too jittery and not refined. Now comes the new 2012 Audi A8L! Unbelievable car. Out drives and performs better than all of the above. Feels like youre driving a Bentley for half the price. Fit and finish, impeccable. Ride is stiff when needed and firm at just the right time. Im a car buff as you can see by all the cars I purchase and Im more impressed with this car than any of the large luxury cars Ive owned, including my past 2009 A8L.

  Truly fine automobile - 2007 Audi A8
  By swissman564 - January 28 - 5:35 pm

  I bought my 07 A8L a year ago at Tysons Audi in Virginia. It had 61,000 miles on it and although it looked practically showroom new in every way, I was a bit worried about spending serious money on a 4-yr old car with that many miles. My worries have been laid to rest 20K miles later. I have owned 4 BMWs (7, 5, and 3 Series) and one Benz. I never liked the Benz but loved all of my BMWs and never thought I could appreciate a car more than a BMW. The 1st time I laid eyes on this car I fell in love with the looks. Mechanically, fit & finish and handling, this is the Ubermachine from Germany. Simple as that. No use enumerating it all. Enough said. Im in love.

  Heartache/headache - 2004 Audi A8
  By heyjude5 - April 18 - 11:51 am

  This car is so comfortable we call it the sofa. It has,however, been a maintenance nightmare. It is constantly in the shop and dealers in northern California uniformly provide lousy but expensive service. When the heater failed while in Minnesota on a winter trip, the dealer groaned when he saw it was a 2004. Nothing but headaches, he told me. Tons of electrical problems to start with, then the list gets mechanical.

  Ultimate Q-ship - 2008 Audi A8
  By tolimits - March 17 - 7:39 pm

  Cleanest design of all large sedans. Extreme comfort and adequate power. Purchased a used one off lease and saved 50% of sticker price. Not sure if it was very well cared for or the build quality is that exceptional, but the car is in nearly brand new condition after 36k miles.

  2011 AUDI A8L - Awesome Car - 2011 Audi A8
  By 2011aviii - December 15 - 6:47 am

  I took delivery of my 2011 A8L earlier this week. I live in the midwest where we received several inches of snow, which turned to ice covering most roads. I had my A8L only one day when I was able to test it in these conditions. I love this car. It handles great in the snow. Prior to my purchase I tested a Benz S550 and a BMW 750LiX drive turbo. Hands down the Audi is the best value for the money. The instruments are a bit complicated, but once you get used to them you appreciate all the car can do. The Audi A8L is very understated, which is one of the reasons why I chose it. I have the Bang and Olufsen sound system and it is amazing.

  Audi A8 - 1997 Audi A8
  By Anonymous - December 6 - 2:00 am

  Very well engineered car. Interior is awesome. Leather is still soft, no rattles, everything works, very solid car. Engine is teriffic. Smooth, quiet, with enough power to get you where you are going. Suspension is a little loose for my tastes, but very smooth over bumps. Steering is feather light and very nice. Transmission had failed at 170k. Not unexpectedly with the D2 A8. Tranny shifts are slow and tall gearing can make the car feel slow when not in the correct gear. Fuel mileage is great for a car this big at about 25 mpg average when using cruise most of the time. Ive had to replace a couple of things here and there but nothing out of the ordinary.
