A gorgeous blend of the coupe and X3, the BMW X4 Concept retains the iconic kidney grilles, bordered with black gloss chrome. Sloping fenders add to its athletic prowess, as do the funky 21-inch light alloy wheels with a bi-color finish. It'll be powered by Beemer's XDrive all-wheel system and word is that its engine will be along the lines of the X3's with a 3-liter diesel also in the running.
