2 BILLION MILES ON-ROAD PERFORMANCE

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.
