Stemco Products Inc. announced its TrailerTail Automatic fuel-saving system, the newest version of its signature TrailerTail products. It deploys automatically when the trailer reaches 35 mph.

Comparatively speaking, today’s over-the-road tractors are slick machines.Improved aerodynamics enables them to slide through the air better than any earlier generation while offering the potential for double-digit improvements in fuel efficiency.

XStream Trucking Inc. launched its aerodynamic device called TruckWings to address the gap between a Class 8 truck and trailer when at highway speeds.

In dueling court filings, Environmental Protection Agency lawyers said they want to postpone the start of a federal appeals court case on the trailer section of the Phase 2 greenhouse gas rule while trailer makers are eager to see the new rule scrapped.

In a move to respond to concerns by the trailer and glider industry, the U.S. Environmental Protection Agency announced it plans to “revisit” its Phase 2 provisions on greenhouse gas emissions and fuel efficiency for medium- and heavy-duty engines.

Ridge Corp. teamed with aerospace technology company FlexSys Inc. to apply its advanced technology to aerodynamic devices used in the trucking industry to reduce drag and improve fuel efficiency.
