BMW is very secretive about its concept and prototype development, but in an unprecedented move the German firm has lifted the lid a little on its top secret development department.
A new video released by BMW shows its hush-hush centre in Munich, used to hone its new cars. The video shows a prototype being cut from a solid piece of aluminium billet, though BMW will not say what this car will eventually become when it reaches the road.
Called Plant Zero, BMW's secret workshop can be seen in this video.
