Times are changing and so do measurement units. Because people in the U.S. are used to thinking of gasoline consumption in miles per gallon, and electric/plug-in hybrids have to do with kilowatt-hours, the Department of Energy is now introducing a measuring unit called the eGallon. The eGallon, as they define it (and it will be […]

100 Year-Old Aerodynamics Problem Solved: Could Increase MPG Dramatically

Ovidiu Sandru — Sat, 27 Sep 2008 15:06:10 +0000

MIT researchers discovered the solution to a problem put 100 years ago by Ludwig Prandtl. It refers to the situation when, for example, a car accelerates up and down a hill, then slows to follow a turn, and the airflow around it cannot keep up and separates from it. This aerodynamic phenomena creates an additional drag, slowing the car, and forcing you to push harder on the pedal, consuming more gas.
