2011 AUDI A8 Pictures and Wallpaper - Audi has launched the next generation of the Audi A8 - the sportiest sedan of the luxury class sets new standards. Its elegantly styled body with the Audi Space Frame (ASF) is aluminum, the engines are powerful and highly efficient, and the power transmission and running gear combine dynamics with convenience. The new flagship's generously designed interior captivates with its luxurious equipment, newly developed control system MMI and the excellent quality of its workmanship. Innovative assistance systems lend even more confidence to driving.

Engines
Superior power and high efficiency - the new Audi A8 makes its debut on the market with a strong V8 engine. With 372 hp, they never fail to impress with their superior power and mighty but discreet propulsion. All engines feature direct fuel injection, and consume 15 percent less fuel than their respective predecessors.
The engine in the Audi A8 has intelligent elements from Audi's modular efficiency system on board. During deceleration the recuperation system converts the kinetic energy to electric power, which is buffered in the battery. In the innovative thermal management a computer monitors numerous actuators for the ideal distribution of the heat flows between the engine, transmission and interior in any situation. After the cold start the engine is temporarily fully uncoupled from the cooling circuit, considerably shortening the warm-up phase with its high loss of friction.
The 4.2 FSI draws 273 kW (372 hp) of power from 4,163 cm3 displacement, generating its maximum of 445 Nm (328.22 lb-ft) torque at 3,500 rpm. It accelerates the Audi A8 from zero to 100 km/h in 5.7 seconds, with the propulsion ending (as in all engine variants) at the electronically controlled speed of 250 km/h (155.34 mph).
The most important reason for this enhanced power is the reduction of internal friction, especially in the chain drive for the camshafts and auxiliaries. The controlled oil pump with changeover between two pressure stages operates with high efficiency. Like all gasoline engines from Audi, the V8 has FSI direct injection. It allows a high compression of 12.5:1, for increased power and efficiency.
