Audi A8 L
The Audi A8 debuted in 1994. Unlike its predecessor, the Audi V8 model, which was built on an existing steel platform, the A8 debuted on the then-new Volkswagen Group D2 platform, an all aluminum monocoque, marketed as the "Audi Space Frame" (ASF), which helped to reduce weight and preserve structural rigidity. The sedan was offered in both the A8 (standard wheelbase), and the A8L extended or long-wheelbase (LWB) version. The A8L adds 5 inches (127 mm) of rear legroom.
In the year 2000 the model year saw a minor front-end restyle, with new, larger, clear headlights, a revised grille, and lower front valance with standard projection fog lamps. On the interior, the seats received a new, horizontal stitch pattern. These restyled cars also featured revised external door handles and an integrated radio antenna.
The A8 received side curtain airbags. Audi introduced its new W12 engine, a compact 6.0-litre unit developed by effectively mating twoVR6 engines together at the crankshaft.
