Like a golf ball, a dimpled car decreases drag by adding turbulence. The result? 11% fuel efficiency at 65mph for 1 mile at full speed. About 16 dimples were used from left to right on the hood. Although this is so simple, only golf balls use this design. Do you think 11% increased efficiency is worth adding dimples to cars, planes, trains, projectiles, and other fast moving objects? There may be other uses for surfaces with gas or fluid flow as well. Feel free to skip through the video.
