Pin the tail on the trailer

ATDynamics announced the commercial launch of its aerodynamic TrailerTail, a rear-drag reduction device the company said is proven to increase fuel efficiency of long-haul tractor-trailers by more than 5%. ATDynamics said it developed the collapsible TrailerTail extension to meet the durability and usability requirements of long-haul trucking fleets, while also dramatically cutting emissions and fuel costs. The company said TrailerTail improves vehicle safety by providing additional stability and reduced spray at the rear of the trailer.

ATDynamics CEO Andrew Smith said third-party SAE J1321 testing showed the TrailerTail boosts fuel efficiency by 5.1% at 62 mph. And, he said, at 68 mph the TrailerTail yields potential efficiency gains of greater than 6%. Based on average long-haul trailer mileage, the device can deliver more than a billion dollars in fuel savings annually to the North American trucking industry, stated Smith.

The TrailerTail is constructed of lightweight, rugged panels designed to endure daily wear and driver abuse, yet ensure smooth opening and closing. A patented hinge system allows truckers to operate doors and access loading bays normally. It collapses from 4 ft. long to 3 in. in less than eight seconds.

ATDynamics is an affiliate of EPA's SmartWay Transport Partnership, a voluntary program that aims to accelerate the trucking industry's efforts to conserve fuel and reduce emissions.
