Having only seen the new BMW 4 Series in a series of photoshopped snaps courtesy of the Bavarian carmaker, we were excited to come across these images on Bimmertoday taken by one of the German forum's followers in his home country. The model spied on the street is a top-of-the-range 435i prototype with the M Sport package, which is even better as this is one of the two models coming to the states. In fact the orange reflectors sitting ahead of the front wheels give the car away as US spec.

Positioned above the Sport Line, the M Sports package includes revised front and rear aprons, large alloys and some interior mods. It will be available from launch exclusively with the Estroil Blue Metallic body color. The 4 Series Coupe will make its live debut at the 2013 Frankfurt Motor Show. Thanks to Tom for capturing the new 4 Series in the wild.
