Rene is from Osnabrück, a little city in Lower Saxony. The German seems to know his way around a car and even collaborated with Lexus on an NX project. However, this BMW X6 is clearly his masterpiece. The technology that makes these color flips possible has been around for many years. In fact, some of you might remember how Hot Wheels had toy cars that changed color when dipped in hot water. How hot must the water be? Probably not that hot, since it’s designed for little kids to play with. However, seeing all that steam rise from the BMW X6 makes you wonder if this procedure is good for the car.
