The North America Council for Freight Efficiency’s (NACFE) Run on Less – Messy Middle, the organization's fifth real-world demonstration to bring clarity to long-haul trucking, will include data from 13 fleets and four powertrain options.
This year's program will focus on heavy-duty Class 8 trucks, sleepers and day cabs, in long-haul return-to-base and over-the-road duty cycles. Lasting three weeks beginning on September 8, 2025, and will feature metrics from data captured by Geotab telematics devices, NACFE's partner for the event.
“The Messy Middle is a time when fleets can choose from a variety of powertrain solutions and other efficiency enhancing technologies,” explained Mike Roeth, NACFE’s executive director. “In our fifth Run, we are featuring tractors powered by diesel, natural gas, batteries, and hydrogen fuel cells. These four powertrain solutions represent currently available options for fleets today.”
Run on Less website will feature profiles for each participating fleet throughout August, leading up to Stories from the Run and data streaming from each truck in September.
“It’s a really nice mix, all performing in long haul,” Roeth said. “I’m thrilled with the diversity: We have the different technologies they’re running; they’re hauling different loads; we have mega fleets all the way down to an owner-operator.”
