ATDynamics has announced its TrailerTail rear-drag reduction device for tractor-trailers has received an exemption from the U.S. Dept. of Transportation’s length restrictions on commercial motor vehicles, meeting federal standards on crash safety, lighting and conspicuity and size.
According to ATDynamics, 2007 third party testing showed the TrailerTail improves fuel efficiency by more than 5% at 62 mph, and the product’s performance has been recognized by both the U.S. EPA SmartWay program and the California Air Resources Board.
The TrailerTail is constructed of lightweight, durable panels, collapsing from four feet to three inches in length in six seconds, and folds flat against rear swing-doors of dry van, refrigerated and drop-deck trailers to maintain normal access to cargo, the company said.
"High-mileage fleets now understand that aerodynamics is a basic way to raise profits during this economic slowdown," said Chuck Horrell, vp of engineering for ATDynamics. "Throughout the rest of 2008, we are focused on delivering TrailerTail units to priority fleet customers and taking orders for 2009 production."
