Carriers across the industry join NACFE's 'Messy Middle' Run
Alternative powertrain pioneers are preparing for this year’s major freight efficiency showcase. The North American Council for Freight Efficiency today announced 13 carriers will take part in its latest freight efficiency demonstration: Run on Less – Messy Middle.
“I’m thrilled with the participation,” Mike Roeth, NACFE’s executive director, told FleetOwner. “I’m excited to help these pioneering fleets tell their stories—that’s what the Run is all about.”
What is the Messy Middle?
Fleets today are stuck between the past of diesel primacy and a future of cleaner powertrains. In this time, alternative powertrains are immature. Carriers must sort through the mess to find the right power options for efficiency, fuel availability, affordability, and more.
“The Messy Middle is a time when fleets can choose from a variety of powertrain solutions and other efficiency-enhancing technologies,” Roeth said. “In this, 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.”
The latest NACFE Run is the fifth iteration of the group’s work to demonstrate freight efficiency technologies and practices. The last Run, Run on Less – Electric Depot, shared how fleets are managing BEV charging needs.
Run on Less – Messy Middle will begin September 8 and last three weeks. The Run will explore real-world, long-haul runs of four different power types: diesel, natural gas, battery electric, and hydrogen.

Who is hauling for this Run?
Each participating carrier selects one vehicle to participate in the event, sharing operational information and its telematics data along the Run.
This Run will feature four diesel, three natural gas, four battery electric, and two hydrogen vehicles. The vehicles and their engines cover both major and minor OEMs.
One of the diesel vehicles, operating a heavy-duty tractor on renewable diesel, is still unannounced. The 13th carrier, Roeth said, is waiting on final official correspondence before it can be announced.
“The one renewable diesel fleet will be named soon. They’re in and committed,” Roeth said.
Among the named carriers are major fleets dominating the latest FleetOwner 500 lists.
The participating carriers are:
Diesel
- Frito-Lay (subsidiary of PepsiCo, No. 2 on the FleetOwner 500: Private) out of Topeka, Kansas, is operating a Volvo VNL sleeper tractor with an Optimus Technologies system using B99 biodiesel.
- Albert Transport out of Laredo, Texas, is operating a 2022 Freightliner Cascadia sleeper tractor with a Detroit DD 15 engine running on diesel.
- Mesilla Valley Transportation out of Las Cruces, New Mexico, is operating an International LT sleeper tractor with a Cummins X15 2027 NOx engine running on diesel.
- To Be Announced operating a heavy-duty tractor on renewable diesel.
Natural gas
- UPS (No. 2 on the FO500: For-Hire) out of Salt Lake City, Utah, is operating a Kenworth T680 day cab tractor with a Cummins X15N engine using natural gas.
- Kleysen Group Ltd. out of Edmonton, Alberta, is operating a Kenworth T680 sleeper tractor with a Cummins X15N using natural gas.
- Wegmans out of Rochester, New York, is operating a Peterbilt 567 day cab tractor with a Cummins X15N engine using natural gas.
Battery electric
- Saia (No. 19 on the FO500: For-Hire) out of Stockton, California, is operating a battery-electric Tesla Semi day cab tractor.
- 4Gen out of Rialto, California, is operating a Volvo VNR day cab electric tractor.
- JoyRide Logistics out of Phoenix, Arizona, is operating a battery-electric Windrose day cab tractor.
- Nevoya out of Colton, California, is operating a battery-electric Freightliner eCascadia day cab tractor.
Hydrogen
- Penske Logistics (No. 16 on the FO500: For-Hire) out of Katy, Texas, is operating a Hyundai XCIENT hydrogen fuel cell day cab tractor.
- Pilot Travel Centers (which owns Pilot Flying J, No. 151 on the FO500: Private) out of Bloomington, California, is operating a Hyundai XCIENT hydrogen fuel cell day cab tractor.
A wealth of industry perspectives
A diverse sample is key for accurate market research. NACFE has no shortage of unique operations among its participants.
The Run goes beyond covering different powertrains: The event will capture a wide range of companies, manufacturers, routes, loads, and geographies.
“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.”
Albert Transport running straight diesel, for example, belongs to Henry Albert: an owner-operator known in the industry for outstanding fuel efficiency.
“His trailer and his tractor are together all the time, so he’s able to put technologies on the trailer that he knows is going to be behind his tractor 100% of the miles,” Roeth said.
Albert uses various aerodynamic solutions like trailer skirts and a trailer tail, as well as solar power to complement his HVAC.
Some of the carriers are repeat participants. Albert Transport, Pepsi’s Frito-Lay division, Mesilla Valley Transportation, UPS, and Penske all contributed to previous NACFE Runs.
What information will NACFE share?
Throughout 2025 and 2026, RunOnLess.com will feature a growing collection of stories and data points.
Throughout August, the Run on Less website will feature profiles for each participant leading up to Stories from the Run and data streaming from each truck in September. NACFE will visit each of the participants’ sites with video crews to record the carriers’ stories.
The three-week Run will feature metrics from data captured by Geotab telematics devices. As the Run gets underway, the group will publish the carriers’ operational data on different dashboards for each of the four powertrain options, sharing key statistics such as miles per kilogram of fuel.
Once the Run concludes, NACFE will share its immediate findings in early October. Throughout the rest of 2025 and into 2026, the group will share deeper analysis and produce reports on its learnings.
Roeth splits the information NACFE provides into “right brain, left brain,” the popular concept explaining people’s preferences for creative or analytic thinking. The Run’s operational statistics provide hard data for real-world hauls using nascent technology, satisfying the more analytic people in trucking. NACFE’s profiles and interviews, meanwhile, share a more personal look into how the carriers collaborate with countless partners to push forward the cutting edge of powertrain tech.
“We all talk about collaboration and how it’s going to take a lot of collaboration,” Roeth said. “Here’s 13 examples of how they’re actually doing it.”
Roeth said that NACFE expects to conduct 100 interviews or more, ranging from the truck drivers to charging companies, manufacturers, and beyond.
