The report — “Terrain, Technology, and Telematics: The Messy Middle Operations Report” — emerged from analysis of the results of NACFE’s latest Run on Less program in September.

Three gas-fueled tractors took part in the Messy Middle, the first such powertrains to contribute to a NACFE program since 2019’s Run on Less Regional Haul demonstration.

Emissions can be reduced, and trucking fleets still can rely on today’s predominant vehicle technologies and fueling infrastructure.

With funding for DOE's SuperTruck program apparently halted, the concept trucks developed during SuperTruck 2 may stand as the final fully realized concept trucks the program produced.

The second day of NACFE's “Messy Middle” demonstration — Sept. 9 — was World EV Day. But the event features almost as many natural-gas powered tractors as battery-electric models.

Hybrid-electric trucks offer a middle ground at lower cost and with less range anxiety than fully electric models.

ArcBest offered the latest window into what to expect from the long-awaited Tesla Semi battery-electric tractor, including energy consumption ratings matching its diesel peers.

The goal of the latest initiative — NACFE’s fifth Run on Less program — is to explore various alternative fueling options and investigate the need for infrastructure changes.

The North American Council for Freight Efficiency's recent report focuses on the increasing availability of cleaner, greener transport refrigeration units.

NACFE announced that it will reveal the fleets participating in its upcoming Run on Less: the Messy Middle test on April 3, and shared more details on the event.
