Here is an excellent never before seen look into BMW's Research and Innovation Center and the prototyping/design process of the first prototypes of each BMW model, each built by hand. Especially cool is the look into a "0 Vehicle," a prototype milled out of a solid block of aluminum to help ensure the highest quality standards. Its purpose is to check that every single body part fits the body exactly to spec. There's also some insight into the camouflaging process.
Any guesses as to which 0 Vehicle is actually being blurred out in this video?
The 0 Vehicle Prototype appears likely to be the future X4 SAV. According to SCOTT26:
The car you see being worked on but cleverly disguised for the viewer is something which is a couple of years away from production. The clue to the model is “Spartanburg” Hence why engineers are learning about the car for creating the production methods needed to build it.
