So it'll get the 3.0T found in the current S4/S5 and the standard 4.2L V8 but how I ask, are they going to squeaze 620 BHP out of their 5.2L V10? I can only assume this is going to be the TFSI version found in the RS6, but it seems odd that they would tune it to be more powerful in the S8 than the RS6. Or maybe that's a typo, maybe 520 HP not 620 HP, let's not forget the current S8 with the 5.2L V10 FSI only makes 450 HP.The Audi A8 will be released with two diesel and two petrol engines. The two engine displacements available will include a 3.0-liter and 4.2-liter V8. It does not appear that Audi will release a hybrid version of the car, unlike the BMW 7-Series and the Mercedes S-Class. However, Audi will likely improve A8 fuel consumption with a start-stop automatic. An Audi S8 could see the benefit of a 620 hp 5.0-liter V10 FSI.It is also looking more likely that the Audi A8 will use the ASF II, the second generation of the company's Aluminum Space Frame. It uses an aluminum passenger cell, with steel and foam built in to reinforce vulnerable areas.
