The 2007 Audi A8 is part of the car's third generation, and it's a full-size luxury sedan celebrated for its elegant aesthetics and innovative technology. The A8 is powered by a 4.2-liter V8 engine that generates 350 horsepower, linked to a six-speed Tiptronic automatic transmission that channels power to all four wheels via Audi's Quattro all-wheel-drive system. Available in two trims: the regular wheelbase A8 and the stretched A8 L, both come heavily loaded with luxury features such as Valcona leather seats, a navigation system, and Audi's MultiMedia Interface system. Safety is highlighted by anti-lock brakes, stability and traction control, front seat side airbags, full-length curtain-type airbags, and front knee airbags. For the 2007 model year, a new adaptive air suspension was introduced offering a balance between smooth ride quality and handling agility.
