Golf Ball aerodynamics
applied to a car 

The dimples on golf balls are designed to reduce air resistance, optimizing their speed and range. This principle intrigued the drivers of the Mythbusters program, who in 2012 explored whether applying a similar surface on a car would improve their efficiency.

They covered a vehicle with clay to simulate a smooth surface and then added dimples. Tests showed that, although the normal car and the clay-coated consumed 26 mpg (9.05 l/100 km), the dimple model achieved a more efficient consumption of 29.6 mpg (7.95 l/100 km) reducing fuel consumption by 12.5%. While the results are promising, additional weight and structural challenges limit their implementation on current vehicles and aircraft.
