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.

Still in Love over 1 year in - 2013 Audi A8
By djefferson - July 21 - 12:15 amI purchased my A8 late spring 2013 and have had no surprises, just pure driving pleasure. This change to Audi was driven by frustration of dealer practices to purchase a new Mercedes S-550/S350 Bluetec at that time a 2012/13 model. I was promised an excellent deal but after almost 4days of back/forth on price and frustration,I went looking for Audi and Im very happy I did. The only reason for not leaving any sooner I had 4 new Benzs within the last 6yrs from that dealership. Forget about loyalty. Love what you drive. I really do. This big girl has excellent dance moves..Rain or Shine, Curves or Straights it drives like a smaller car begging to show off. Both City/Hwy MPG is impressive.

Surprising Luxury and Performance - 2014 Audi A8
By clarkg - July 29 - 8:52 amI have owned Audi A8 sedans previously but switched to Mercedes S Class a few years ago - all of these high tech sedans can be problematic due to the complexity of their electronic systems - so be prepared to buy only from a dealer with 5 star service - recently, I was intrigued by the 2014 A8L TDI diesel sedans specs and options so I acquired one - it does everything right, especially fuel mileage which surpasses my expectations - the A8L is "sized right" as compared to the lumbering S550 - the diesel performance is outstanding - the electronic gizmos are entertaining but most are not necessary for daily use - cons - lots of road noise from stiff tires, mediocre stereo, electronic failures

1999 Audi A8 - 1999 Audi A8
By audi99 - July 19 - 10:30 amGreat Car. I have owned this car since 2000 with 18,000 miles and now have 152,000. I have minor repairs done to this car like a few of the 4 ball joints that are on both sides of the car. Cruise control brake switch and thermostat. The front seat is sagging a little bit and I may take it apart to adjust. The center arm rest broke so I repaired it myself. I replaced the timing belt and water pump at 100,000. I recommend changing the thermostat at same time as timing belt and water pump. I have not had any transmission problems and I have not changed transmission fluid. I dont drive it hard and fast and that policy seems to help longevity of any car.

Pinnacle of Technology, Luxury, Comfort and Prestige - 2013 Audi A8
By magician2166 - July 6 - 7:38 pmLadies and Gentlemen, If You are on the market for a luxury vehicle, please do yourself a huge favor. Test drive this marvel of German engineering. No words can describe the adrenaline from its powertrain, comfort of its heated, cooled and massaged seats and the luxury of its interior. I drove many luxury cars before, but I was totally stunned and amazed by every attention to even the smallest detail the designers had paid in this spaceship. This is truly the pinnacle of technology, luxury, comfort and prestige.

Three great months and counting... - 2006 Audi A8
By dognmonkey - June 29 - 9:59 amNew to me 2006 A8L with 73k miles. Premium, sport and massage packages. This year is the first year with the single grill and the last year with timing belt engine. Ive had 98 A8 for 7 years - loved the car and now this one is amazing. No wonder many people moved from BMW, Mercedes to Audi. Air suspension is comfortable and very convenient to raise the car up when going to a complex that has many tall speed bumps. The car is so powerful, fast but very nimble (drives like a small car) and still get average 19MPG (26 hwy). Soft close doors are nice (the doors got sucked in if close half way). I drive people who dont know Audi on my A8L and theyre amazed at the comfort and design.

The Best of 2005 luxury car - 2005 Audi A8
By hazar - June 3 - 1:10 pmI traded in my big failure 07 BMW X5 with this beauty : and I am very pleased with this move. . It was nightmare to own a very expensive SUV like the 07 X5 ( top of the line ) which give us only troubles... the driving of this car is nothing close to any of BMW & MB .. I drove the S class, C63 -AMG , as well as the BMW , but never tried the Audi which I realize the mistake I did .. This car is a luxury feeling , sporty feeling , fun feeling.. great interior , high quality material , smooth engine.. This is the one to have in your Garage for all season ... you should know that you will not be able to drive MB in snow... It was a big failure m at least to me...

130K and STILL going strong... - 1999 Audi A8
By pocketchange - April 10 - 11:35 amAfter two years of ownership I have no complaints. When first purchased I decided to replace or rebuild all the systems sos not to have any concerns for a few years. Having little service history I continue to think this was a positive move in spite of the moneys spent. My greatest problem was locating a clean example of an A8 (this took months) due to their limited numbers and dubious ownership. For my limited investment, I am more than pleased with this very fine example of German craftsmanship.

2012 A8L has some LEMONS to admit and RESOLVE - 2012 Audi A8
By grnltrn - February 9 - 1:35 pmAudi is building a few (hopefully) LEMONS and attempting to outrun their flawed automobiles with marketing dollars. A search of the AUDI forums disclose a number of late model A8L vehicles with similar problems and a lack of acknowledgement by Audi that they intend to stand behind their warrantees. Audi is intimidating dealers, directing them to not service the car or refusing to pay them for warrantee repairs. Seat sensor - airbag deactivation Mirror heat not working tranny hard downshift Radio station refresh Cell phone pairing fails Console rattle Door close/locks malfunction when cold Clunk on acceleration MMI system fails to play .wav and .flac files Int lighting flickers

Audi Company - 2011 Audi A8
By domehead - January 29 - 8:02 amI have owned a 2011 A8 and 2012 A6 and the basic cars work very well. But I am very disappointed in Audi Company in their technical service department and also with the National sales team. My A8 was having a electrical /mechanical issue with the relay that controls the power brake system. My understanding is that Audi technical support instructed the local Audi Mechanic to wrap insulation around the relay so I would not hear the relay closing and opening. The next item was to relocated the relay to another spot in the car so I would not hear the relay. Both of this approaches did not address the core issue of the problem why is the relay started working that way. Instead it appears that Audi was trying to mask the issue hope the owner would go away. This is very serious problem with this car and I would not aspect Audi would try to cover up of the issue. The next point is that I ask the local sales manager to see what Audi would do for a trade value on my car towards a newer one. The answer he give was that Audi would not help out in this matter besides not fixing the issue. Needless to say that the way Audi has handle this matter is very disappointing for a company that is trying to make inroads in the high end market.
