(Skip to details on the: A8 L W12)
A8s feature a version of Audi's distinctive single-frame grille and adaptive headlights, as well as side mirrors with turn-signal lights. The A8 L rides on a 121-inch wheelbase, which is 5.1 inches longer than the base A8. The A8 L's rear doors are 5 inches longer than those on the shorter-wheelbase version for easy entry and exit.
The regular-length A8 has an overall length of 199.3 inches, a width of 74.6 inches and a height of 56.9 inches. It is the shortest in height of its competitors, and its width is comparable. The A8's length is close to that of the BMW and Lexus, but nearly 6 inches shorter than the Mercedes-Benz S-Class.

Standard safety features include:
The top-of-the-line A8 L W12 features all-wheel drive and a 6.0-liter W-12 engine rated at 450 hp and 428 pounds-feet of torque. The A8 L is also available with the 4.2-liter V-8 that's in the A8. Either engine drives a six-speed Tiptronic automatic transmission. This was the first production car in the world to use LED technology, which uses extremely low power consumption, for its daytime running lights. The A8 L W12 has distinct rocker panels, too.
Audi says the A8 L W12 "accommodates four in supreme luxury." Seating for five is available in the W12 and standard in the A8 L 4.2 models. Standard equipment includes keyless entry and engine start-up, a navigation system, four-zone automatic climate control, a front and rear Parktronic parking system, and electric sunshades for the rear and side windows.
