The Audi A8 is a full-size luxury sedan manufactured and marketed by the German automaker Audi since 1994. Succeeding the Audi V8, and now in its fourth generation, the A8 has been offered with both front- or permanent all-wheel drive—and in short- and long-wheelbase variants. The first two generations employed the Volkswagen Group D platform, with the current generation deriving from the MLB platform. After the original model's 1994 release, Audi released the second generation in late 2002, the third in late 2009, and the fourth and current iteration in 2017. Noted as the first mass-market car with an aluminium chassis, all A8 models have used this construction method co-developed with Alcoa and marketed as the Audi Space Frame.

A mechanically upgraded, high-performance version of the A8 debuted in 1996 as the Audi S8. Produced exclusively at Audi's Neckarsulm plant, the S8 is fitted standard with Audi's quattro all-wheel drive system. The S8 was only offered with a short-wheelbase for the first three generations, being joined by a long-wheelbase variant for the fourth generation.

D2 (Typ 4D; 1994–2002)

Development

In 1982, Ferdinand Piëch signed an agreement with Aluminum Company of America. The objective was to design and develop a car that would be substantially lighter than any other vehicles in its class (to compensate for the fact that standard all-wheel drive was around 100 kg (220 lb) heavier than competitors' rear-wheel drive). In the late 1980s, it was decided that the target vehicle would be a successor to the V8 (Typ 4C) flagship introduced in 1988. By 1990, a final design by Chris Bird and Dirk van Braeckel was chosen and frozen for series production in mid-1991. In September 1993, the Audi Space Frame (ASF) Concept was unveiled at the 1993 Frankfurt Motor Show (IAA) as a D2 Typ 4D prototype in polished aluminum. Pilot production began in December 1993 and development ended in early 1994, at a total cost of $700 million (£418.1 million).

Negative 1998 Audi A8 car reviews

Julian Stroman 2025-01-02

I really enjoy cruising at high speeds of 85-90. The ride is quiet, refined, and solid, with more than enough power available for highway speeds. You can drive for extended miles on the highway and arrive feeling relaxed. The large fuel tank will allow you to go over 600 miles before refilling, but your bladder probably won't last that long without a stop. If you're looking to get the most for your money, a used A8 is a much better value than a new A4 for the same price.
Paxton Hyatt 2024-05-23

Congratulations on reaching 200,000 miles on your car! It sounds like it runs well and is very comfortable to drive. It must be a great car for student drivers to have fun in.
Wyman Rosenbaum 2024-03-23

After owning numerous BMW's and driving many other cars over the past twelve years, I must say that this car is a true revelation. I never expected an Audi to provide me with such an incredible driving experience, all while maintaining the utmost comfort and style. It is truly a beautiful car.

Adonis Heaney 2024-11-29

I bought a Quattro A8 that had just come off a lease and I must say, it's been a great car. Even after two years and 96K miles, I've only experienced a few minor electrical glitches (outside mirror motor). The quality and performance of this car is truly superb.
Ransom Moore 2024-09-24

I've been driving this car since 2002 and it's been an amazing experience. It's so much fun to drive, especially considering its size. The engine is incredibly powerful, and I'm glad it's legal in the United States. Despite its size, the space frame makes it feel light and nimble, yet solid as a rock. Living in the mountains of Utah, the Quattro is a must-have. I can see myself buying A8's for many years to come.
Boyd Emmerich 2024-09-23

You've owned some impressive cars in the past, including the Lexus LS400, Mercedes S500, and BMW 750IL. However, it's clear that this car is your favourite to drive! The car handles ultra-smoothly at speeds in excess of 100 mph, making it perfect for the autobahn. It's also impressive that you're able to get over 25mph on the freeway! The Quattro is a real asset to the car, giving you confidence on snowy or rainy roads - something that many other luxury car makers struggle to match. Overall, this car is a great deal for anyone looking for ultimate safety and performance, especially if you're able to find a good deal on a used one.
Taylor Huel 2024-09-20

Hi there! I hope you're doing well. I just wanted to share my experience with my car. I bought it used back in 2002 and have driven it for 80,000 miles since then. I have to say, the build quality, handling, and performance are all great! However, I have had some small issues with it over the years. At 170K miles, it's now on its third transmission, which is a bit of a bummer. But, on the bright side, I haven't had any other mechanical issues. The engine is fantastic and still tight and strong, using no oil. I've also had the chance to drive the 4.2 AWD models, but I have to say, I prefer the handling of my FWD 3.7 model. It's only 3600 lbs, which is about the same as a Subaru WRX. Interestingly, the 3.7 seems to have virtually disappeared from the roads now, though. At current rock-bottom prices, these are a stupendous bargain! Thanks for reading.
Jettie Borer 2024-09-15

This must be the best car I've ever owned. I've owned Mbs and tons of other great cars, but nothing compares to this. Its awesome power is amazing, and it accelerates from 80-110 quicker than 0-60 (which is a big deal). The brakes are strong and it's lightweight...
