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.

The fourth Run on Less program in NACFE’s Run on Less initiative will involve four different powertrain solutions: diesel, natural gas, battery-electric and hydrogen fuel cells.

Based on data from some of the North American freight industry’s largest carriers, fleet-wide fuel efficiency averaged 7.77 mpg in 2023, compared with 7.62 mpg in 2022.

The research, published Oct. 18, marked NACFE’s first analysis of alternatives available to fleets, with the introduction of all-electric TRUs in its early stages.
