If you thought that having an ultra smooth surface that cuts through the air with razor sharp efficiency, you were wrong! As surprising as it may be, the Mythbusters on Discovery have found out that a car with dimples like those on a golf ball actually increases fuel efficiency. The original myth is that a car covered with dirt is more fuel efficient than a clean car because of the golf ball like dimpling effect that the dirt has on the car. However, they found out that dirt doesn't have any significant influence on the car's fuel efficiency. So as usual, they went to the extreme creating a car that actually had golf-ball like dimples on it by using clay. The standard car with the clay smeared on top without the dimples did 26mpg at a constant 65mph but after the dimples were created, the car did over 29mpg! The theory states that because of the dimples, it reduces the drag on the car thus making it more aerodynamic than say, a normal smooth shape. And it turns out to be Myth - Plausible. Quite amazing that they actually went out and did it. But can you imagine cars of the future looking like this just to improve a car's fuel efficiency? I don't think so but this looks amazing if you think of the principle behind it. It does look like a golf ball inspired car to the largest extent!
