Earlier this year, we wondered out loud if it was really possible to achieve drastically improved fuel economy figures through the use of a dimpled vinyl automotive wrap. The premise is pretty simple: just as golf balls and recent high-tech sporting outerwear feature an uneven surface to cut down on wind resistance, a similar pattern could be applied to the outer skin of an automobile to achieve greater aerodynamic efficiency.
A company called Fastskinz believes it can increase overall vehicle fuel mileage by up to 20% with its decidedly simple vinyl wrap, and Popular Mechanics decided those claims were worth investigating. To properly test the Fastskinz wrap, PM obtained two identically-prepared 2009 Ford Flex crossovers. Both vehicles had about 8,000 miles on the odometer, featured the same powertrain combination and had similar levels of equipment.
