The Audi A8 is a four-door, full-size, luxury sedan car manufactured and marketed by the German automaker Audi since 1994. Succeeding the Audi V8, and now in its third generation, the A8 has been offered with both front- or permanent all-wheel drive—and in short- and long-wheelbase variants. The first two generations employed the Volkswagen Group D platform, with the current generation deriving from the MLB platform. After the original model's 1994 release, Audi released the second generation in late 2002, and the third and current iteration in late 2009.
The major difference between the A8 and the A8 L is the extra 5.1 in. of space between the front and rear axles, giving a wheelbase of 122.9 in., along with an overall length of 207.4 in. The rear passengers see all the benefit, with longer doors for easier ingress/egress as well as interior space that Audi classifies as "opulent."
The W-12 is hooked to Audi’s new ZF-sourced eight-speed Tiptronic transmission, as is the A8’s 4.2-liter V-8, and the gearbox routes power to the standard Quattro all-wheel-drive system.
