LOUISVILLE, Ky. — ATDynamics is coming out with a Nano version of its TrailerTail that will comply with Canadian regulations.

The new model was announced today at the Mid-America Trucking Show. Bob Ozden, chief operating officer of ATDynamics said the Nano version will extend two feet from the rear of the trailer and deliver fuel savings in the range of 4%. The expected savings of the mini-trailer tail have not yet been scientifically proven.

The TrailerTail Nano will also be suitable for double trailer applications and intermodal operations, Ozden said.

Meanwhile, popularity of the device continues to increase in the US. ATDynamics announced Werner Enterprises recently placed an order for 130 units after field testing the product and another “Top 10” US fleet has committed to the product, Ozden said. The four-foot TrailerTail, which can be used across the US, has proven to reduce fuel consumption by 6.6% when travelling at highway speeds.

Ozden said fleet customers always combine TrailerTails with side skirts, which together can provide fuel savings of 7/10ths of a mile per gallon. Tails alone provide savings of 4/10ths mpg, he noted, providing a payback in six to 24 months. ATDynamics sells Transtex Composite side skirts, providing a complete trailer aero solution.

ATDynamics has delivered more than 4,000 TrailerTails to date. They’re priced at US$2,800 for individual orders with volume discounts available.

Five to 10 unit are deployed in the US every day, Ozden pointed out. So far, the device has accrued 14 million miles of real-world experience with only about a half dozen failures, Ozden noted, and he blamed those on improper installations by dealers. ATDynamics has dismantled its dealer network and is in the process of building a new one that will better serve the industry’s needs, Ozden said.

The Canada-compliant TrailerTail Nano is expected to weigh about 100 lbs and will be available this fall. It will come with a three-year warranty.
