I think the European version of the 3.0 liter has had 260-270 horsepower for a few years and direct injection alone would do that. My 2007 X3 had either 255 or 260 HP and then they dumbed it down for 2011 to 240. The reason I bought a 2007 X3 was the additional HP after owning a 2004 X3 which either had 230 or 240 HP. It doesn't matter because we will get the N20 which I'd rather have for the torque and mpg's anyway.
