Before Audi turns a big sedan into a coupe with the A7, its going to have one last crack at making a large sedan into a large sedan with an updated A8. Just like previous renderings and rumors, the new A8 should get a sleeker and more aggressive design inspired by the A7/Sportback concept. Just like smaller models, Audi's next flagship will utilize the MLP platform, which will allow for the engine to be mounted further back and more weight directed toward the center of the car.

As far as the engine lineup goes, the middle of the road should stay the same with at variety of V6 and V8 engines in both gas and diesel forms offered over the international line. What is unclear just now is that if Audi continues to go for smaller engines with turbocharging, a four cylinder engine may become the base powerplant. Rumors suggest 230 hp version of the 2.0-liter TFSI engine from the Volkswagen Group's parts bin may become the lowest rung on the A8 ladder. For the same reason a four-banger may make an appearance in the large sedan, it may also jeopardize the top of the line W12 engine or possibly the Lamborghini-inspired 5.2-liter V10 in the next R8.

Any engine shake ups should not have a huge effect on the U.S. market, where we currently have only V8 engines or higher, and will likely never see a diesel version of the big sedan. The official debut of the next A8 will be made in September at the Frankfurt Motor Show, and the sales will begin in 2010.
