The new 2015 BMW X4 is set to debut at the New York Auto Show but a prototype has been spotted with no camouflage in Germany. This particular X4 has the xLine treatment and is finished in a Deep Sea Blue Metallic. I must be honest, apart from the very bland wheels, this is a good looking new Beemer. I absolutely loved the concept version and once again it has been toned down for production but I still find it very appealing.
