Video shows how BMW prototypes are born and tested at a facility in Munich. A secret prototype appears in the video with the image blurred so that we cannot make out what it its.

They call it Plant Zero.

Somewhere amongst the array of buildings at BMW's Research and Innovation Center in Munich is the place where prototypes are born.

This video shows the people in the Experimental Vehicle Shop (Plant Zero) where first-off prototypes are built and assembled by hand.

Those 'zero' prototypes are made from a solid block of aluminum and the development process is not only meant to create the best possible vehicle, but also devise the most efficient methods to produce the model on BMW's vehicle assembly lines - all highly digitized and robotized.

A secret prototype for a future vehicle appears in the video with its image blurred so that we cannot make out what it is (F30 3-Series).

We also get to see an X6 prototype and learn why BMW prefers that swirling white-on-black camouflage film over black plastic and metal body panels.

Our favorite part of the the 2:10 mark a BMW employee from South Carolina says the word "vee-hicle" in his charming Southern drawl. We just like that, you know.
