The biggest changes come inside. Bringing BMW's smallest off-roader in line with the X5, trim will be dramatically upgraded. High quality soft-touch plastics will replace the cheap-feeling material found on the dashboard, while equipment levels are expected to be revised to improve value for money.
Under the bonnet, the X3 will feature cutting-edge powerplants from the new 3-Series. The 2.5-litre petrol unit will get a 23bhp power boost to 215bhp, while the more costly 3.0-litre engine is also uprated from 231bhp to 254bhp.
Extra sound-deadening material will improve refinement on all variants. But no chassis alterations are expected - rather than deliver a complete overhaul, BMW intends to address specific minor weaknesses in the X3 package.
Facelifted models will go on sale in Germany in September next year, with right-hand-drive cars due before the end of 2006. Competition in this class is set to be fierce, with the Volvo and Land Rover using the next Ford Mondeo platform.
