The third-generation Audi A8 (D4, type 4H) represented the pinnacle of luxury and technological expertise from Ingolstadt upon its release. Built on the ASF (Audi Space Frame) aluminum structure, it stands out for its surprising agility for its size, its standard quattro AWD (except hybrid), and its exceptional interior finish. The late 2013 facelift (Model Year 2014) introduced the famous Matrix LED headlights, revised engines to meet the Euro 6 standard, and further improved soundproofing. Although its build quality is flawless, it is an extremely complex vehicle whose maintenance requires a substantial budget, particularly on the V8 petrol and W12 engines.
The Audi A8 D4 is a fascinating technological showcase that offers an exceptional price-to-performance ratio on the used market due to its heavy depreciation. However, this depreciation is justified by prohibitive maintenance costs. If you are looking for a petrol engine, the 3.0 TFSI is the most reasonable and reliable choice. The V8 versions (4.0 TFSI and S8) offer supercar performance but require absolute vigilance regarding the turbo recall (oil strainer), otherwise you risk bills exceeding €10,000. Buy only with a complete maintenance history from the dealer network or a recognized specialist, and keep a comfortable financial reserve for unforeseen events (air suspension, electronics).
