Not sure if the states is going to get the motor, but the inline 6 has 3 turbos and produces a whoping 545 ft.lb. tq at 2000 RPM. Its rated at a little over 380 hp and projected to get 38+ in the 5 series wagon. I am not sure about the gas consumption figures as the high 20's seems more realistic, regardless here is one of the few articles out there I have read.

Amazing stuff for sure. The Porsche wagon gets a little less @ 67 mpg.
