Rear-drag reduction device provides fuel savings as much as 5%

Louisville, KY, March 27, 2008 – A rear-drag reduction device, ATDynamics’ new aerodynamic TrailerTail®, will be attached to the rear of the industry’s first EPA Certified SmartWay® trailer, a 4000D-X® Dry Van built by Utility Trailer, and showcased in the Environmental Protection Agency’s SmartWay® booth (#13052, North Wing) at the Mid-America Trucking Show, March 27-29, in Louisville, Kentucky.

ATDynamics developed the collapsible TrailerTail® extension to meet the durability and usability requirements of long-haul trucking operations, while dramatically cutting emissions and fuel costs by as much as 5%. The TrailerTail® also improves vehicle safety by providing additional stability and reduced spray at the rear of the trailer.

Third-party SAE J1321 testing conducted by Robert Transportation at Energotest 2007 in Montreal, Canada showed that the TrailerTail® boosts fuel efficiency by 5.1% at 62 mph. At 68 mph the TrailerTail® yields potential efficiency gains of greater than 6%. Based on average long-haul trailer mileage, the TrailerTail® can deliver more than a billion dollars in fuel savings annually to the North American trucking industry.

The TrailerTail® is constructed of lightweight, rugged panels designed to endure daily wear and driver abuse, yet ensure smooth opening and closing. A patented TrailerTail® hinge system allows truckers to operate doors and access loading bays normally. The TrailerTail® collapses from four feet to two inches in length in less than 8 seconds.

“The least aerodynamic way to carry goods down the highway is in a large rectangular box,” explained Andrew Smith, CEO of ATDynamics, Inc. “Forward-thinking fleet operators are now serious about improving the aerodynamics of their fleets. Starting with the TrailerTail® and with other products now in the pipeline, our goal is to dramatically improve the sustainability of the global freight industry.”

ATDynamics is an affiliate of the Environmental Protection Agency’s SmartWay® Transport Partnership, a voluntary program which accelerates the trucking industry’s efforts to conserve fuel and reduce emissions.
