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.

  $90,000 piece of junk - 2007 Audi A8
  By W. Stiles - July 12 - 5:40 pm

  I bought this CPO 2007 Audi A8L with 33,000 miles on it and have had nothing but headaches since owning it. It has been in the shop 4 times in less than a year for numerous electrical problems. The Audi A8 customer service line is a complete waste of time as they do nothing, but come up with excuse after excuse as to why the car is not performing as it should. We have had 2 aluminum wheel failures where the tire immediately loses pressure. One of these episodes almost caused my wife to be in a serious car crash on the highway. Audi says it is still safe and I completely disagree. I am now in the process of selling and getting a more reliable car (Mercedes or BMW)

  A lot of car for the money, great value - 2004 Audi A8
  By monzavifar - May 28 - 4:29 pm

  About 3 months ago I bought a 2004 A8L with 70K miles (black on beige) for $16K. I gave my BMW 530i in trade. At the beginning I missed the sportiness of the Bimmer but after a while I got used to it. Considering the fact that the car is a lot bigger and heavier than the Bimmer it is understandable that it doesnÂ’t sprint. My A8L has lots of gadgets that my Bimmer did not have. A few days ago I put 19 inch OEM wheels + new summer tires on it, man, it rocks now. I used to be a Bimmer fanatic and was looking for a 750Li for a while but after driving this car I am reconsidering. So far knock on wood have not had any mechanical issues with it. It is a lot of car for the money and very much fun to

  Best Luxury Sedan Value - 2010 Audi A8
  By Audi Fan - May 26 - 12:05 am

  This is my second audi,I upgraded my 2008 A6 to a 2010 A8. I also considered the BMW 550i GT and 7 series. I chose the Audi because it offered the best combo of luxury, performance and value. If you look at raw numbers of horse power and 0 to 60 times then the BMW shines, but if you drive the two cars there is no comparison. The Audis acceleration is like butter, the car seems to move effortlessly. I was always skeptical about whether or not the price jump from the A6 to the A8 was really worth it, but after driving both there is a big difference and I believe the cost is worth it. To be clear I am a fan of the A6, but I felt it was just a bit under powered with the 3.2 FSI engine.

  Fantastic Car.. - 2007 Audi A8
  By J Montana - May 25 - 10:49 pm

  This car has it all. Looks, performance and there are not many on the road. Every other car in LA is a 7 series or S550. This is one amazing car. Tight , great motor, short wheelbase handles great. Bose stereo is more than adequate.

  Best car Ive ever had - 2007 Audi A8
  By Justin Fontaine - May 24 - 6:07 pm

  Ive had the privilege of owning/leasing BMWs ( 5 series ) a couple of 911s and a Mercedes S class and I have to say that this A8 is tops for performance, class, reliability and most of all individuality. In LA there are thousands of S Class and 7 series. I can honestly say Ive not seen one other dark blue short wheelbase A8 with the performance 20" wheels in 3 years of driving here. The car is special in every way. The handling for a large sedan is spectacular due to the aluminum body and quattro. The fit and finish inside of the amaretto interior are awesome. Power is smooth and refined. Great Bose system. Biggest issue will be whether or not to buy it after the lease! Not one problem

  A Great Car - 2001 Audi A8
  By moose - May 12 - 2:00 pm

  Ive had this car since new and have @ 67,000 miles on it. Had an extended warranty that was a nice addition, b/c out of warranty repairs can be costly. It most comfortable and the gas economy tho not great can be up in the 25-26 range on a trip. One of the drains on the sunroof still is blocked after 2 attempts to fix.

  All Cars have Maintenance Costs. - 2001 Audi A8
  By T in CA - April 11 - 5:32 pm

  Bought the car certified-preowned, (used). Car was in a front end/rear end collision so price was lower than listed. In spite of the collision history, body panel fit is excellent. Things that have gone wrong...whoever put the drain system for the moonroof in did so incorrectly causing a leak when it rained, the dealer took three trys to get it fixed. Other than that MAP air sensor, trans filter service and power steering fluid leak repair. Above and regular maintenance is all that Ive had to have done to the vehicle. Out of warranty so sought out non-dealer service which halved the cost of repairs.

  Maybe the only 3.7 model left in USA? - 1997 Audi A8
  By Geoff - April 10 - 1:08 pm

  I bought mine used in 2002, have driven it 80,000 miles since. Build quality, handling, performance are great. Many small things have failed though, and at 170K miles its on its third transmission (!). No other mechanical issues though. The engine is fantastic, still tight and strong and using no oil. Ive driven the 4.2 AWD models as well, and I have to say I prefer the handling of my FWD 3.7 model. Weight is only 3600 lbs, about the same as a Subaru WRX. The 3.7 seems to have virtually disappeared from the roads now, though. At current rock-bottom prices these are a stupendous bargain.
