Audi A8

The second-generation A8 built on Audi's D3 platform was introduced in early 2003. The model was longer than the previous generation, with room for four or five large adult occupants in the cabin depending on rear seat configuration.
Two body variants of the second generation A8 are offered, the A8 and the long-wheelbase A8L. The A8L adds five inches of rear legroom.
Audi restyled the D3 platform A8 range slightly in 2005, endowing all variants with a taller, wider single-frame grille inspired by that of the Nuvolari concept car. The top-of-the-line 12-cylinder W12 version was the first model to be equipped with this grille; V8 models were outfitted with the new grille the following year. In addition to the styling update, new engines became available to European and Asian market customers. The entry-level 3.0 L V6 was replaced with a new 3.2 L unit featuring FSI, which it shares with the new A4.
The second-generation A8 introduced the 4.2 L Diesel V8 engine. Generating 240 kW (326 PS) of power, this is the most powerful diesel engine Audi has ever offered in a passenger automobile. The engine uses two turbochargers and two intercoolers, with each turbocharger functioning exclusively for one bank of four cylinders.
For MY 2008, the A8 received new electronic safety systems. "Audi Side Assist" detects cars in the A8's blind spots. "Audi Lane Assist" helps when the driver attempts to change lanes without signaling first.
