The full UT-6-plus system from SmartTruck has four separate components that work in harmony to sculpt the air flow under, over and around the trailer. The heart of the system, the UT-1 under-tray device looks simple enough, but there's more going on down here than meets the eye. Smart Truck's chief scientist, Mike Henderson, explains how it works.

What conclusion is the reader supposed to come to when two sets of properly conducted and documented fuel economy tests yield significantly different results? It would be easy to dismiss one of the tests as inaccurate, but that would still not answer the question, which one is wrong? What if both of them are right? A recent news article published such test results and yielded a significant discrepancy. A week-long deep-dive into fuel economy testing and real-world fleet results reveals that we s

Most of the low-hanging aerodynamic fruit has already been plucked from the engineering tree. Truck makers and their design teams are now actively exploring options they would have ignored a decade ago. It's all about the cost of fuel. The big shift to slope-nosed aero trucks began nearly 20 years ago, and since then engineers and designers have been refining the design. Today we see tweaks and twists yielding just the tiniest of gains, yet they are all steps in the right direction. What follows is a pictorial review of some of the changes we've seen in recent years -- some dramatic, some very subtle, but all aimed at killing fewer bugs. By Jim Park, Equipment Editor
