The Audi A8 (2004), codenamed 4E, 4E2, and 4E8, marks the second generation of the flagship luxury sedan from the German automaker. Unveiled in 2003, this iteration brought a significant leap forward in both design and technology, building upon the success of its predecessor. The A8 (2004) was available in a range of body styles, including the standard long-wheelbase sedan, a shortened wheelbase version, and an extended wheelbase variant for chauffeur-driven clientele. The design language, penned by Walter de Silva, embraced a more elegant and restrained aesthetic compared to the previous generation. It featured a bold, upright grille, sharp lines running along its flanks, and a sweeping roofline that culminated in a distinctive rear end. This sophisticated exterior was complemented by a luxuriously appointed interior, featuring high-quality materials and advanced technology for its time.

Underneath the sleek exterior, the A8 (2004) offered a powerful and refined driving experience. It was available with a range of V6, V8, and W12 petrol and diesel engines, paired with either a six-speed manual or a six-speed Tiptronic automatic transmission. The chassis was also significantly advanced, incorporating aluminum construction for enhanced weight reduction and handling precision. Key features notable for its time included adaptive air suspension, quattro all-wheel drive, and an array of electronic driver assistance systems, such as ESP (Electronic Stability Program) and ABS (Anti-lock Braking System). Moreover, the A8 (2004) was amongst the first cars to offer a full-fledged multimedia system with a large, color touchscreen and navigation capabilities, underscoring its status as a leading technological innovator in the luxury automotive segment.
