The 2005 Audi A8 is a full-size luxury sedan from the model's second generation. It has been touted for its sophisticated, yet understated, design and stellar performance. It's powered by a range of engines, starting with a 3.0 TDI V6 producing 233 horsepower, through to a powerful 6.0 W12 gas engine delivering 444 horsepower. Audi's celebrated quattro all-wheel-drive system comes standard, supplemented by a 6-speed automatic transmission. Inside, the A8 is notable for its exquisite interior, featuring Audi's MMI (Multi Media Interface) system with a 7-inch screen. Safety credentials include ABS, ESP, multiple airbags and an optional adaptive cruise control. Although unchanged dramatically from the previous model year, the 2005 A8 did receive some refined retuning of the suspension for an even smoother ride.
