A large rectangular box is the worst shape to pull down the road at highway speed.
ATDYNAMICS HAS REDEFINED THE SHAPE OF THE MODERN SEMI-TRAILER, engineering the first commercially successful rear-drag aerodynamic device in the history of the trucking industry.
TrailerTail® technology streamlines the airflow around a semi-trailer and reduces the low pressure suction drag that occurs at the back of the trailer which acts as a vacuum pulling the trailer backward and reducing its fuel efficiency.
Patented, award-winning TrailerTail® technology improves a trailer’s fuel efficiency by over 5% without hindering cargo capacity, loading or unloading.
CERTIFIED to deliver 5.54% fuel efficiency gains at 65 mph based on SAE Type II testing
VALIDATED by the U.S. EPA
COMPLIANT with 2010 CARB regulations for trailer aerodynamics as a stand-alone device
EXEMPT from U.S. DOT length restrictions
PROVEN to perform in drop and hook dry van and refrigerated trailer operations in ALL weather conditions
ESSENTIAL to the profitability and competitiveness of any fleet operation accruing over 25,000 miles per year, per trailer at highway speed
