This is a common approach for very early prototypes. BMW takes an early M3 test mule they don't need any longer, apply some of the changes/modifications, and test the car. Later prototypes will reflect the actual car better, but this spotting is huge as we know for sure now how serious BMW is about the lightweight E90 M3.
