This incredible process is how automakers make their cars extremely fuel efficient

Aerodynamics is one of the biggest things car companies have to keep in mind for automotive design, speed, handling, and fuel efficiency.

For nearly 100 years, automotive engineers have thought to model cars so that they can cut through wind better.

Now, we have production cars with extremely low drag coefficients, road cars that can travel over 700 miles on a full tank, and race cars that can corner at over 200 MPH. It's likely none of these feats would be possible if it wasn't for the aerodynamic testing capabilities automotive manufacturers have access to today.
