PHOENIX. The TrailerTail 2011 aerodynamic trailer fairing has shown up to a 6.6% improvement in fuel efficiency in third-party tests, according to the manufacturer ATDynamics. Introduced at the American Truck Assns.’ annual convention here, the next-generation design of its device incorporates thermoplastic composite materials for lighter weight and a collapsible design that eases trailer access, according to the company.

Featured on the ATA exhibit floor was a Mesilla Valley Transportation trailer fitted with the new device, which mounts on the rear trailer doors, folding close when the trailer needs to be loaded or unloaded. The truckload carrier plans on retrofitting 3,500 units with the new TrailerTail model, a move it estimates will reduce its diesel consumption by 1 million gals. a year, according to ATDynamics.

“Rear air drag reduction is increasingly recognized as the largest cost saving opportunity for fleets to increase fuel efficiency,” said CEO Andrew F. Smith. “When combined with side skirts and other aerodynamic modifications, trailer aerodynamics equipment can deliver over 12% fuel economy improvement to trucking fleets.”
