Annual Fleet Fuel Study

August 24, 2016 NACFE Releases it’s 5th annual Fleet Fuel Study Report.  It can be downloaded for free at  Please have a look at it.  We expect it will help you in your effort.

    The North American Council for Freight Efficiency (“NACFE”) has built on what has been called the “The most comprehensive study of Class 8 fuel efficiency adoption ever conducted”. In 2015, the group now has 14 fleets operating 53,000 tractors and 160,000 trailers reporting on the adoption of 70 technologies for the past 12 years. Much can be learned from this data and is presented below. In summary, these fleets saved $477M in fuel expense during 2014, equaling about $9,000 saved per truck. If all of the approximately 1.7M tractor trailers did the same the savings would be about $15B for us truck operators in Class 8 over the road alone.

Testing Reports

During May of 2016, NACFE assisted XStream Trucking, with a real world fuel economy test of a product they are developing to close the gap between Class 8 tractors and trailers.  During these tests (details of how the test was conducted is provided in the report) a 2.5% reduction in fuel use was witnessed when the device was deployed.

Xstream GapGorilla Fuel Economy Test Report

November 2013, NACFE was engaged to help plan, execute and validate a fuel efficiency test of a platooning technology under development by Peloton Technology. The report below details a 10% fuel consumption reduction for the trailing tractor trailer and 4.5% for the lead combination, when electronically connected at 36 feet separation and 64 mph. A modified SAE J1321 test protocol was used in cooperation with CR England on Interstate 80 west of Salt Lake City.

Peloton Technology Platooning Test

During the summer of 2011, NACFE helped execute and monitor a 5,000 mile fuel economy test for various tire configurations for Michelin NA. This test was conducted as a high mileage confirmation of the improvement in fuel efficiency of various tires in doubles trailer operation.

Other Reports

Uptake and costs of NA trailer fuel efficiency technologies

-NACFE again has collaborated with ICCT to interview the industry on fuel efficiency technologies. This report shares learnings from such an effort on technologies available to fleets for improving the fuel efficiency of NA 53 foot trailers. Items included were tires, tire pressure systems, gap reducers, underbelly devices, skirts and trailer tails. The full report can be downloaded here.  Please feel free to contact us with any questions or comments.

Market Barriers

NACFE is proud to announce that the Market Barriers to Technologies for fuel economy sponsored by the ICCT, is now published. It has been a pleasure working with fleets, owner operators, truck and trailer builders, manufacturers and others on this significant study. Contact us at with questions or comments.
