Here are some A8 rumors:

Facelift in early 2013 because some exec not too happy with the styling. I agree partially, the A8 looks quite bad in photos and from the front in real life. Basically the photo used in the article is what I am talking about. It does look great from the side, rear 3/4 and not too bad from the back.
400+ hp V8 TDI which is already known. The 6.3 W12 will be turboed for the A8 for extra "torque". The engine is perfectly capable of 650 horsepower but I can see Audi quoting a lower figure to protect Bentley and Porsche.
Next generation A8 might ditch the aluminum spaceframe concept for an aluminum/steel/composite combination. The A8 might also be built on the Porsche led MSB platform (next Panamera, Bentley Continental, Flying Spur) and have rear wheel drive/ rear biased all wheel drive. Discuss.
