OptiFlowTM AutoTail is here
An EPA’s SmartWay 4% verified solution & GHG phase 2* BIN III certified rear aerodynamic tail
OptiFlowTM AutoTail, is the new patented1 benchmark in rear aerodynamic solutions. A reliable, powerful and yet compact tail that competes against larger, bulkier devices. Sharing design experiences from its international made counterpart, this Tail has several modifications that make it a unique offering for the North American market.

Construction & Operation
OptiFlowTM AutoTail has been submitted to the harshest environment under automotive testing standards, assuring peace of mind, lowest subjected total cost of ownership for a solid return of investment.
The lightweight plastic construction of the components are durable and reliable when compared to heavier and expensive metal components.
OptiFlowTM Autotail is not only an EPA GHG phase 2 BIN III solutions, it also offers SmartWay’s verified 4.3% fuel savings.
By connecting to the trailer’s ABS the AutoTail will deploy at a speed of 45 miles per hour and as the trailer slows down or brakes the AutoTail will self retract at speeds below 15 miles per hour. No driver interaction is required, an invisible product to the driver that perform aerodynamics when it counts.
Loading or unloading, AutoTail is designed to keep cargo handling unaffected. The AutoTail patented top-panel design allows its deformation to wedge into the reduced available space between door and trailer side wall when opened reducing rear-door opening angle. The trailer can operate as usual, top marking lights are unhindered and doors chainstays will attach, just as in any other trailer door application.
Panels and struts are made of robust automotive-grade injection molded TPO plastic; brackets, stiffeners, pneumatic cylinders and connectors are manufactured from high quality stainless steel and aluminum for maximum rust resistance.
The most salient aspect of the Autotail design is its aerodynamic dimensional shape. Panels were carefully designed to outperform standard flat panels. The panels are shaped to closely follow optimum aerodynamic flow. The side panels have a meeting horizontal area that overlaps the top panels to provide an unhindered joint.
It is surely the first Tail that has a gradual transition, merging the trailer’s side with the tail’s lateral panels. And when looked at closely, its elongated top panels pop up. This, is not just an aesthetic gimmick; it is in fact an aerodynamic feature. At the sides air flows unhindered from trailer to tail, but at the top an offset was required by law to allow top marking-lights visibility. To counteract the effects of such offset in the flow, this newly designed component will re-attach the flow, reducing rear low body pressure and therefore increasing the overall system performance.
This, resulting from months of CFD2 and wind tunnel testing with more than 100 tail designs making this particular design the undoubtable selected winner.
