The Audi A8 III, known as the third generation (2009–2017), stands as the flagship luxury sedan from the German marque. Coded internally as Typ D4, it debuted late in 2009 and remained in production until 2017, receiving a significant facelift in 2013. Sales in the US began in 2010 through Audi's official dealer network. The model rides on the innovative MLB (Modular Longitudinal Platform), enabling an extensive aluminum body structure that cuts weight while boosting rigidity.
Design highlights include sleek, aerodynamic lines (drag coefficient of just 0.26), the signature Singleframe grille, and the world's first full-LED headlights on a production car. The elegant silhouette exudes prestige. Under the skin, it impresses with quattro all-wheel drive, adaptive air suspension, potent engines ranging from a 3.0-liter diesel to a 6.3-liter W12, plus cutting-edge features like the MMI system with touchpad, night vision, and adaptive cruise control. The third-gen A8 set the benchmark in the luxury segment, going head-to-head with the Mercedes S-Class and BMW 7 Series.
What’s New Compared to the Previous Generation
Compared to the second-generation A8 (Typ D3, 2002–2009), the D4 brought sweeping updates that made it sharper, lighter, and more advanced. Styling shifted to crisper lines and full LED lighting: the D4 looks more aggressive, with a stretched wheelbase (standard 2992 mm, long-wheelbase 3122 mm) that enhances proportions and rear-seat space. The body shed about 187 pounds thanks to even greater aluminum use (up to 92% of the structure), improving handling, efficiency, and performance.
The MLB platform replaced the old D3 architecture, paving the way for new tech such as electromechanical power steering and optional torque-vectoring quattro. Engines were modernized: turbocharged V6s (3.0 TFSI/TDI) and V8s (4.2 FSI/TDI) replaced older units, cutting fuel consumption by around 22%. Tech leaped forward with Matrix LED headlights (post-facelift), Audi Pre Sense collision avoidance, night vision with animal and pedestrian detection, and upgraded MMI navigation with HDD storage.
Comfort soared with superior sound insulation (acoustic glass, active noise cancellation), a roomier cabin, and options like massaging seats and rear-seat entertainment. Safety remained top-tier: eight airbags, ESP with off-road mode, adaptive headlights. Overall, the A8 III became lighter, more tech-laden, and more refined while preserving Audi's signature DNA.
US Used Market
On the American used market, the 2009–2017 Audi A8 remains a sought-after choice among luxury-car enthusiasts, executives, and comfort-focused buyers. Listings on platforms like CarGurus, Autotrader, and Cars.com (as of early 2026) show steady availability, reflecting sustained demand thanks to timeless design, strong reliability, and accessible parts through Audi's widespread dealer network.
Approximate market price range in the United States: $10,000 to $35,000 (realistic used values depending on condition, mileage, and trim). Entry-level examples – pre-facelift models with 120,000+ miles, often 3.0 TDI or 3.0 TFSI – typically fall in the $10,000–$18,000 bracket. Top-spec variants (S8 or W12, lower mileage) can reach $30,000–$40,000+. Average transaction price hovers around $18,000–$25,000. Diesel versions with quattro and long-wheelbase command the strongest interest due to their efficiency (roughly 20–25 mpg combined) and suitability for long-distance American driving. Gasoline engines are more common stateside, with the S8 prized by performance enthusiasts.
Facelifted models (2014–2017) with Matrix LED headlights and updated electronics see higher demand. Hybrids remain rare but attract growing interest. Overall, the A8 D4 offers compelling value – true flagship luxury at the price of a mid-size premium sedan.

It suits executives, long-distance drivers, and families who want spacious, refined transport with a premium badge – without the new-car premium.
