Verified Aerodynamic Technologies

Aerodynamic technologies minimize drag and improve air flow over the entire tractor-trailer vehicle. Aerodynamic technologies include gap fairings that reduce turbulence between the tractor and trailer, side skirts that minimize wind under the trailer, and rear fairings that reduce turbulence and pressure drop at the rear of the trailer. Using fairings in combination with one another (or, in a few cases, when used alone) have the potential to provide an estimated 5 percent or greater reduction in fuel use relative to the truck's baseline, when used in conjunction with an aerodynamic tractor on long haul Class 8 trucks, in highway type operation. This reduces NOx emissions, saves up to 800 gallons of fuel, and eliminates over nine metric tons of greenhouse gas emissions per year.

EPA has verified the following categories of aerodynamic technologies:

  • Trailer Gap Reducer and Trailer Side Skirts (used in combination with one another); Trailer Boat Tail and Trailer Side Skirts (used in combination with one another);
  • Advanced Trailer End Fairing; and,
  • Advanced Trailer Skirts.

To be eligible for DERA funding, aerodynamic technologies must be on EPA's SmartWay verified technology list
