Adoption of Trailer Aerodynamics Continues to Grow, Report Finds

This story appears in the March 14 print edition of iTECH, a supplement to Transport Topics.

Fleets have ramped up their investments in trailer aerodynamics systems in recent years to improve fuel economy, and federal regulations are expected to drive further adoption, a new report found.

Today, approximately a fourth of all dry van and refrigerated trailers on the road in the United States have at least one aerodynamic technology installed, according to a new report from Trucking Efficiency, a joint effort between the North American Council for Freight Efficiency and Carbon War Room aimed at boosting freight efficiency.

The report also said prices for trailer aerodynamic technologies — particularly side skirts — have decreased significantly due to a greater competition among suppliers, higher sales volumes leading to lower costs and increased availability of devices directly from trailer manufacturers.

In fact, more than 30% of new trailers are being equipped with trailer aerodynamic devices, the report found.

“Fleets have moved from asking why they need aerodynamic devices on their trailers to determining when and how they will add them,” said Mike Roeth, NACFE’s executive director.

Regulations such as the federal government’s proposed Phase 2 greenhouse-gas emissions standards are expected to spur further growth in the deployment of aerodynamic systems. That proposal, issued in June by the Environmental Protection Agency and the National Highway Traffic Safety Administration, would introduce the first federal trailer efficiency standards starting in 2018.

The Trucking Efficiency report also noted a “clear prioritization” on which areas of the trailer the industry is addressing through aerodynamics.

The top priority has been the trailer underbody, with nearly 30% of new trailers equipped with side skirts followed by the back of the trailer with about 5% of trailers equipped with tail devices, the report said.
