The new Audi A8 - the sportiest sedan in the luxury class
Fascinating sportiness, innovative technology and superior comfort: Audi is bringing the next generation of the A8 to the starting line. The new flagship demonstrates the brand’s proverbial Vorsprung durch Technik with its light aluminum body, its powerful and highly efficient engines, the further improved MMI operating system, new driver assistance systems, the full LED headlights and an elegant interior with a craftsman’s level of workmanship.
With all this technology the new Audi A8 offers the perfect synthesis of dynamics, perfection in design, workmanship and pioneering efficiency.
“The new Audi A8 is the sportiest sedan in its segment,” says Rupert Stadler, Chairman of the Board of Management of AUDI AG. “It combines numerous functions in a new and intelligent way. And it’s unmatched in the stylistic elements and impression of the interior.”
The new luxury sedan, to arrive at U.S. dealerships in late 2010, is a technical work of art. Its elegant and forceful body is an aluminum Audi Space Frame (ASF), weighing about 40 percent less than a comparable steel structure. The interior is captivating, with its new and spacious design and uncompromisingly high-quality workmanship full of attention to the smallest detail. The comfort on board is first class – from new, emotionally charged ambient lighting to the luxurious, power adjustable seats in the rear.
Superior power and high efficiency – the new 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 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 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.
