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.

  Luxury without flaunting your wealth. - 2007 Audi A8
  By DLBoston - July 23 - 12:22 pm

  I have owned Jags, Mercs, BMW, and Cadillacs and they all have their outstanding features. The regal look of the Jag, the comfort of the Merc and the Cadis smooth ride. The Audi L W12 (my first) took the best features of luxury automobiles in its class and built a car that has lived up to my expectations. Yes the car has a six figure price tag fully loaded however the car delivers on all its promises and gives the driver a senseof royalty without being to flashy. Would it be fair to say that I am an Audi man for life? YES!!

  Outstanding A8L - 2005 Audi A8
  By William H. Malone II - June 19 - 12:15 pm

  This my second A8 experience. The first is a 2000 A8 that now has 122000 flawless miles. This is the reason that we purchased the 2005 A8L. Best vehicle that I have ever owned. Outstanding in ALL areas and a complete pleasure to drive. You can keep the BMWs and Mercs. No contest. Audi understands and understates their cars. The car speaks for itself. It shouts OUTSTANDING as it passes everything on the road.

  Finally a competitor to big Germans - 2005 Audi A8
  By nick - June 18 - 10:28 pm

  Gorgeous body, fit and finish. Impressive looks, great engine, agile, stately, big but easy to drive like a midsize sedan. Few flaws however: CD changer in the glove compartment must go, bad location for cup holders, short lived original equipment tires (Continental CH95), problems with automated trunk, immediately after purchase navigation upgrade was issued for $299 (should be covered at least for a year or upgraded with a discount).

  A Great Car - 2007 Audi A8
  By TDL - June 1 - 11:41 pm

  This is my third Audi, and I find them to be a superb balance between a luxury and sporty design philosophy. The vehicle feels like a smaller, more nimble vehicle, but has more room than practically anything else in this segment. The interior design and fit and finish are best in class. The S8 variant is an attractive alternative, but we also had a sporty car in the garage, and decided to go with the long wheel base and the extra rear leg room which precludes the S8 package. But, I also feel the extra length gives the car a more flowing appearance in the side view. Fuel economy is what you expect in this class, and when considering the performance (and the way I drive), it is rather good.

  A luxury sedan wannabe - 2005 Audi A8
  By ggill - May 15 - 4:35 pm

  Ive had problems with this car ever since it was delivered. Immediately had a problem with the instrument cluster. Outside temp read below zero, so a/c would not work. Transmission noise required 10 days in shop to fix. Had several recalls. Now electronic controls (MMI) dont work. Although still under warranty, Audi wants me to pay, so they can pull and inspect unit before covering. If you call their customer service center in Michigan, be prepared for a long wait before you can speak with an "advocate", and expect a poor result. Im buying a Lexus 460, and pity whoever buys my used Audi.

  Great car but... - 2004 Audi A8
  By King Daddi - May 9 - 3:01 pm

  I traded a 2001 BMW 740iL for the A8L. The car seems great but less than 3 weeks after I bought it, it was in the shop for a system failure and the entire dashboard display has to be replaced plus several other items. Check the service history. I was told by the tech that the 04s are "just temperamental". If you can, hold out for a 2006/07 Get a CPO and still under Audi warranty or you will be in big trouble. Gas mileage seem very poor.

  Quattro - 1998 Audi A8
  By Lambillotte - April 5 - 2:47 pm

  Well built and high roadability particularly in northern climates where the quattro really helps. Hardly any minor defects. Excellent fit and finish. Only drawback was that at 150,000 miles had several expensive repairs that were not routine maintenance including failure of the power windows, pulley bearing failures and computer controls failure.

  Just a great car - 2004 Audi A8
  By A Beauty - February 18 - 5:59 pm

  A dream car. Excellent pick up, great MMI, really simple to use, very few steps to do anything important (i.e. radio, heated seats etc.). Spacious like you wouldnt believe. Great handling, fun to drive. Highly recommended, but you do have to expect issues when you buy German.
