Digging Deeper into NACFE’s Run on Less Truck Fuel-Efficiency RoadShow

">The North American Council for Freight Efficiency released an in-depth report on its Run on Less fuel-efficiency roadshow. The three-week event last fall demonstrated that it's possible to get 10-plus mpg in real-world Class 8 freight-hauling operations. The report released at the Technology & Maintenance Council's annual meeting March 4 digs into the strategies used by the seven participating fleets.
During the 17-day run, seven trucks from participating fleets Albert Transport, PepsiCo's Frito-Lay Division, Hirschbach, Mesilla Valley Transportation, Nussbaum Transportation, Ploger Transportation and U.S. Xpress, averaged 10.1 mpg, exceeding the 9 mpg goal and saving $2,877 gallons of fuel and $7,193 compared to the national average of 6.4 mpg for the over-the-road tractor-trailer population.
NACFE drew the following conclusions from the Run on Less event:
- 10 mpg does happen in the real world
- Conditions matter and need to be understood for decision-making
- High mpg requires efforts in many areas
- Telematics reports and data logging are worthwhile investments.

The 17-day Run on Less fuel-efficiency event featured diverse truck routes, all converging in Atlanta. (Routes displayed using the MyGeodata Cloud online tool.)
">Fuel-efficient truck specs
The trucks, which were 2015 model year or newer, used commercially available technologies. Including engines and engine ratings for maximum fuel efficiency, downsped powertrains, considerable attention to aerodynamics, and in some cases idle reduction equipment, including solar panels.
Some of the specifications employed across the seven participants were quite similar, others very diverse. Features that were common across all seven included:
- All-inclusive tractor aerodynamics, including sloped hoods, bumper dams, aerodynamic mirrors, chassis fairings, full height roof fairings, cab extenders, vented mud flaps and drive wheel fairings with wheel covers.
- Low rolling resistance tires on most wheel ends.
- Automated manual transmissions.
- Downsped powertrains at 2.67 at faster.
- Low viscosity engine lubrication.
- Engine programing for idle shutdown and diesel-fired heaters for idle ...Read the rest of this story
