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 ...

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 ...

Aerodynamic add-ons for tractors and trailers can deliver measurable fuel savings and faster ROI. Most solutions are designed for easy installation and minimal maintenance to reduce downtime. Products ...

You might have seen semi-trucks with tiny Airtabs lining their body and trailer. These are for more than just show; they also ...

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 ...

Aerodynamic drag reduction remains a pivotal area in automotive design, balancing fuel efficiency with performance and safety. Advances in computational fluid dynamics (CFD) modelling, experimental ...

The USPTO has approved a Stellantis design for an angled pickup truck bed cap aimed at reducing aerodynamic drag and improving fuel efficiency. Stellantis patented an “Angled Bed Cap for Truck” to ...

In nature, the most aerodynamic shape is that of a drop of water, which has a coefficient of drag (Cd) of 0.05. Unfortunately, this is not a practical shape for a vehicle. An object's Cd, or how much ...
