I wouldn't include this information unless you have evidence of these changes/timing. You must be reading something I haven't seen, because there has been nothing regarding timing that I am aware of. If there is something, can you provide a link? Thanks.

"I have read that documents outlining the LCI for the E70 started reaching dealers in the last couple of days, so you may have already seen internal documents about this. It appears that production will begin in March for Mid-April delivery of the 2011 X5’s, which are receiving minor changes to the bumpers and lights. More importantly, I am hearing that the N55 twin-scroll turbo with 300hp & 295lb-ft of torque will be replacing the naturally aspirated 3.0 liter as the base engine. Not only is this a more powerful engine, it gets better gas mileage."
