Someone here posted some time back that when BMW facelifts the 7 Series, they will also increase the power of the 4.4-liter and 6.0-liter engines. The 745i will become 400 horsepower and the 760i will become 500 horsepower. If they put the 6.0-liter engines in the 5 and 6 Series, they will start rivaling the M5 and M6!
