How GasPods Save Fuel

Reducing the drag coefficient of your vehicle results in a reduction in the fuel it burns. GasPods do just that!

At various points on every vehicle, air disengages from its surface, creating turbulence, or drag. Overcoming that drag consumes fuel. Reducing that drag saves fuel. GasPods are aerodynamic, pod-like devices, that when placed before the point where turbulence forms, enhance the flow of air to make the vehicle more aerodynamic. The more aerodynamic the vehicle, the easier it is to power through the air.

According to auto industry experts, “For a full-size truck, a change in drag coefficient of 0.01 is approximately equal to an improvement in fuel economy of 0.1 mpg on the combined city/highway driving cycle, … The same drag coefficient reduction can improve a car’s fuel economy by approximately 0.2 mpg.” (Improving Aerodynamics to Improve Fuel Economy at, 05/05/2009)

Computational fluid analysis (simulated wind tunnel tests) revealed a reduction in the drag coefficient of between 5.2% and 6.7%, when GasPods were placed 10″ before the rear windshield and along the rear sides of a Volkswagen Golf. That translates into just under a 5% reduction in fuel consumption for the vehicle tested, or around an extra gallon of gas for every tank full!

These fuel savings have been verified in field tests, with drivers realizing between 2% and 17%. Variation is due to differences in the aerodynamic characteristics of the vehicles driven, and whether driving is primarily in the city or highway. Field testers driving primarily in the city a less aerodynamically designed 2004 Volvo XC 70 AWD reduced gas consumption by 1 mile per gallon for an extra 16 miles per tank of gas. A freeway commuter driving a 2009 Toyota Yaris saved 3.7 miles per gallon – an extra 40 miles per tank of gas!
