One reason car companies camouflage their test cars is to prevent other automakers from stealing their designs and prevent the general public from getting too excited about upcoming models. To prevent keen eyes from seeing a new model ahead of time, automakers use camouflage, which can be either vinyl wraps or additional body panels that bulk up a car’s shape. However, a vinyl wrap alone will make it easier for engineers to gauge real-world fuel economy. The concept is the same as the Dazzle camouflage, It’s been given a great deal of layering and depth to throw off phone and camera focusing, so shots end up either out of focus or distracting attention away from the important bits automakers haven’t yet revealed to the world.
