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.

  THE BEST EVER! - 2007 Audi A8
  By Brian - November 30 - 11:11 am

  I just picked up my A8L 4.2 V8 2 weeks ago and it is THE most luxurious car Ive ever owned. The attention to detail of the interior leather and wood is sheer perfection. The drive is amazingly smooth but as precise as a surgeons scalpel. I cant believe that a large luxury car like this handles so well. Not to mention the all wheel drive gives me a feeling of confidence on the road that is a true benefit. Mine is Black with Amaretto Leather and the B & O stereo! The rear seat room is amazing and my girls love the power rear seats!

  Bellisimo! - 2007 Audi A8
  By Svetlana B. - November 18 - 9:48 pm

  The most beautiful car Ive ever owned. Stunningly luxurious interior, classy exterior, polished demeanor, great acceleration from 350hp V8, dazzling 19" wheels that turn heads, super attention to detail, nimble handling that belies its size, and so much more. I bought it last week, and already took it across the state line!

  An Ideal Car - 2006 Audi A8
  By Richard Nigro - November 17 - 2:24 pm

  This car is a unique blend of soft, smooth ride without the swaying of some cars. This car also exhibits oustanding handling and acceleration. I also own a MB E320. The interior in this car is beautifully fit and finished. The drivers seat is perfectly contoured and 12 (16?) way adjustable.The controls are logically arranged and are easy to use. The MMI eliminates a clutter of dials and buttons,and is easy for an average person to use (unlike the MB 320 computer which is impossible). Do yourself a favor and consider this car for your next vehicle.

  Sporty A8 - 2007 Audi A8
  By JRH332 - November 11 - 10:42 am

  I purchased my A8 on 11/04/06. This is not the long wheelbase model but the shorter A8. If my dealer told me the truth this the only A8 in the Audi Central Region with the 20" Sport Package. The car is not only a knock out in looks but a blast to drive. Great performance plus all the luxury you could ever want. I traded in a 2006 Infiniti M45 Sport so you know I had to go some to find a better vehicle! Audi needs to advertise this model more.

  Great Car - 2006 Audi A8
  By Capt Hill - November 10 - 11:51 am

  This was the third Audi Ive bought from this dealer. Great service, and we were totally happy with the transaction. The car is built like a bank valult and drives very responsively, even more responsively than my 2002 A6 4.2 sedan, which is also a great car. Creature comforts are amazing. The massaging seats are a plus, and seat heating is easy to set and change. Cupholders are OK, but do not quite accommodate the fancy Audi leatherette cups we also bought. They are too tall for the holders. Technically, I have not yet mastered the Navigation or the phone, but we are getting there. A truly great car, indeed.

  Simply awesome... best of the class - 2006 Audi A8
  By TTaylor - October 27 - 11:29 am

  Getting straight to the point, I have owned BMW 7 series, Lexus 430 and Mercedes S series vehicles.The Audi A8L is undoubtably the most complete car I have ever owned (compared to the others). Yes, you lose a little performance to the BWM (very little, almost hard to notice), the perceived elite status of the Mercedes (notice I said perceived...but not realized in the ownership experience)and the softness/comfort of the Lexus. Now for tag line, if you want completeness, with very little compromise to the perceived strengths of the other three purchased the Audi A8L. The true and most complete athlete of the class. I may own an Audi A8L for many years to come.

  Simply Outstanding Auto - 2003 Audi A8
  By Fanning - September 8 - 2:13 pm

  This is my fourth Audi, my second A8, this time an A8L with most of the options. Best automobile I have ever owned and operated. Quiet, sure-footed, solid vehicle that pampers the occupants in sumptuous surroundings. Contrary to some reviews, I find this car to be quite economical regarding gas consumption as I am getting between 34 and 37 mpg cruising at 60 mph (100 kmh). City mileage around 20 mpg. At 44000 km (27000 mi) changed tires for Michelin Pilot A/S. Any complaints about rough ride and road noise evaporated with the new rubber.

  MB 550 vs. the Audi A8L 4.2 - 2006 Audi A8
  By Chris - September 5 - 8:12 pm

  I love my A8L the MMI is perfect and easy to use, the Bose stereo is so much better than my MB Harmon Kardon stereo. The 4 wheel drive is nice to make a 4 when you make a u-turn.

  A8L will always be my only car - 2004 Audi A8
  By Audi onwer for life - August 28 - 6:23 pm

  I purchased my 2004 A8L after owning a 1999 model. This car is a major advancement over the previous generation car which was a great car in its own right. It is a technological wonder mechanically and the interior is darn near a work of art. The structure is rock solid with no body flex and the suspension is a perfect balance of comfort and handling. The engine has excellent power and smoothness yet sounds like a performance car when pushed hard. This is the most intelligently designed car in the world according the to the window sticker and I couldnt agree more. As long as Audi continues to build this model I will own one.

  Best sedan yet - 2005 Audi A8
  By The2thmover - August 16 - 12:23 pm

  After 2 Mercedes, and 1 BMW I can easily say this is my favorite sedan I have owned. After one year of ownership I can say that reliability has easily exceeded that of Mercedes with no issues to report. It plays up to the "drivers car" side of me without being as unforgiving as the BMW. Fit, finish, and quality of interior matierials are remarkable. Every car has quirks, but the quirks with this one are either petty or livable. An outstanding automotive value.
