The A8's fuel consumption of each of the engines available has been reduced by as much as 22 per cent. The 3.0 TDI with front-wheel drive to follow later emits only 159g of CO2 per kilometer (255.9 g/mile) and with 6.0 litres of fuel per 100km (39.20 US mpg) it improves fuel economy.
The new luxury sedan is expected to arrive at dealerships in early 2010. Its body is made up of an aluminum Audi Space Frame (ASF), weighing about 40 per cent less than a comparable steel structure.
The Audi A8, when combined with an optional navigation system, its Multi Media Interface MMI includes the MMI touch. This MMI touch system enables the driver to control functions intuitively. MMI navigation plus is networked with the advanced driver assistance and safety systems. It reads road ahead in the navigation data and provides this information to control units for automatic transmission, headlights and refined Audi adaptive cruise control with stop & go function.
According to Audi, new A8 will initially be offered with either of two engines, a 4.2 FSI with 273 kW (372 hp) and a 4.2 TDI, packing 258 kW (350 hp). These will be followed by a 3.0 TDI with 184 kW (250 hp), which is a new design. The output and torque of all engines have been increased.
Rupert Stadler, chairman of Audi, said: "The new Audi A8 is the sportiest sedan in the segment. It combines numerous functions in a new and intelligent way. And it is unmatched in the stylistic elements and impression of the interior that will be the best in operator comfort and control, while still meeting our customers' budget needs."
