Trailer aerodynamics devices can improve fuel efficiency by 1% to 10%. The gap between the trailer and tractor, the underbody, and the rear of the trailer are three areas ripe for drag reductions. A ...

You may have noticed semi trucks with long pieces of metal hanging down toward the ground -- this is a side skirt, and here's what they're meant for.

This trailer owned by Illinois-based Nussbaum Transportation has both an aerodynamic “boat tail” from Stemco TrailerTails and extra-long trailer side fairings it developed with Wabash. Photo: Nussbaum ...

The winds of change continue in the aerodynamics biz, as universities and manufacturers find ways to streamline tractors and trailers in order to reduce air drag and thus, save fuel. Ad Loading ...

Trailer aerodynamics drives fuel efficiency; pairing aero tractors with non-aero trailers limits gains. Fleets benefit from optimizing trailer gaps, underbody, and rear designs for reduced drag. Data ...

If you're pulling a camper with an electric truck or SUV like a Tesla Model Y, a slipperier shape is the key to preserving range. With their large size, the average camping trailer isn’t a very ...
