2010 refresh
The modified X5 will be revealed at Geneva Motor Show in March 2010. The updates are focused on a revised range of engines and exterior changes[7]. All models are provided with an eight-speed automatic transmission as standard and permanent BMW xDrive. Exterior changes are among other things selective changes to the front and rear, e.g. enlarged cooling intakes, new fog light, new headlight design with optional LED corona rings (European models only), LED daytime running lamp function position, optical underride protection and LED taillight as well.

I'll find out the answer later today or tomorrow morning
