Self Study Program 662 – Audi A8 (type 4N)

VAG SSP 662. This self study programme describes the design and function of the Audi A8 (type 4N). Launched in 1994, the Audi A8 was the world’s first large-volume production car with a self-supporting aluminium body. Since then, Audi has built around a million cars with the Audi Space Frame (ASF) body. Its successor, the A8 (type 4N), continues this tradition. The design of the new A8 perfectly embodies the fundamental qualities for which Audi is renowned – sports appeal, light-weight construction and quattro all-wheel drive.

Stylistically, the Audi A8 marks the beginning of a new design era for the entire brand. The front end with its wide, upright Singleframe grille and the fluid, muscular body symbolise sporty elegance, sophistication and progressiveness. The defining design feature of the new Audi A8 is spacious luxury; the cabin of the Audi A8 resembles a spacious lounge with generous proportions.

In comparison with the predecessor model, both body variants are noticeably longer. The interior of the luxury saloon is deliberately minimalist, with a clearly defined and strictly horizontal architecture. Audi carries its high quality standards into the digital age with a radically new operating concept. The driver controls the infotainment system with fingertip control on the large display.

The driver can use a second touchscreen display on the centre tunnel console to access the air conditioning and comfort functions as well as making text inputs. The MHEV (mild hybrid electric vehicle) technology of Audi is based on the newly developed 48 volt electrical system – it supplies the 12 volt system, which in this case becomes the electrical subsystem.
