According to German-based Automobilwoche, Audi has revealed that the next generation Audi A8 luxury sedan is set to arrive sometime in 2010. More than just the approximate launch schedule, we also know that Audi’s flagship model is also expected to feature two diesel and two petrol powerplants.

To help Audi keep up in the “fuel efficiency” bandwagon, the auto maker will also add an engine start-stop system while the super-fast S8 model is expected to carry a 5.0 litre V10 FSI that is good for 620HP.

Another improvement that we might see in the new Audi A8 is the utilization of the Audi’s second generation Alluminium Space Frame (ASF 2) which features an aluminum passenger cell with steel and foam built in to reinforce certain vulnerable areas. Expect a preview of the Audi A8 at the upcoming Frankfurt Motor Show which is set to kick start in September this year.
