CARB Compliance 

The California Air Resource Board (CARB) has adopted a regulation to improve the fuel efficiency of tractor-trailers. We invite fleets that are evaluating compliance strategies to consider ATDynamics products that by themselves achieve standalone compliance with requirements for trailer aerodynamics, and which together maximize CARB compliance at a profit. 

U.S. EPA SmartWay

SmartWay is a voluntary partnership of government and the freight transportation industry dedicated to reducing greenhouse gas emissions and improve fuel efficiency. ATDynamics has been a SmartWay Affiliate since 2008. 

SAE J1321 Testing

SAE J1321 testing is the industry standard for measuring increases in fuel efficiency attributable to aerodynamic technologies. In addition to laboratory optimization and fleet evaluation, ATDynamics relies on SAE J1321 testing to evaluate the aerodynamic performance of its commercial products and of technologies in the pipeline.
 

Do-It-Yourself Savings Gauge  

No online calculator can predict your on-road fuel savings. But we hope that our DIY version will give you a figure that's in the ballpark. If you need a more specific calculation, our sales team is available to walk you through a comprehensive NPV (Net Present Value) analysis.

Aerodynamics 101
 
A tractor-trailer is exposed to four main areas of aerodynamic drag, which together account for 2/3 of fuel consumed by the vehicle at highway speeds.

Aerodynamics & Safety  

Aerodynamic technologies improve visibility for drivers, trailing trucks, and passenger vehicles by reducing spray, and enhance stability by streamlining airflow, particularly at the rear of a tractor-trailer. The relationship between aerodynamics and safety is ripe for further study.
