“This is the most comprehensive study of Class 8 fuel efficiency adoption ever conducted.” - Truck News

Data and Tools that help you decide which technologies will help you save fuel dollars

​This report contains the results into the adoption of various products and practices for improving freight efficiency among 19 major North American fleets. The scope of this work encompassed Class 8 tractors (daycabs and sleepers) and trailers in regional and long-haul applications. Fleets providing data for this 2017 study include Bison Transport, Cardinal Logistics, CFI, CR England, Challenger Motor Freight, Crete, Frito-Lay, Maverick, Mesilla Valley Transportation, NFI Industries, Nussbaum, Paper Transport, Prime, Ryder System Inc., Schneider, United Parcel Service, and US Xpress. One more fleet has supplied data in the past, but has not for the past few years. The primary goal was to study the fleets’ levels of adoption of 85 technologies and practices, and the results those drove in each organization. All 85 technologies, up from 69 in last year’s study, are currently available and not prototypes, validation test units, or pre-production units. This study focuses on technologies purchased and implemented onto a fleet’s trucks and trailers.

 The primary finding of this report is that the 19 fleets studied are increasing their rate of adoption of these technologies, and that they are enjoying improved fuel economy as a result. The overall adoption rate for the technologies studied in this report has grown from 17% in 2003 to 42% in 2016. Not all technologies could be applied to a single tractor-trailer, as some are clearly an either-or decision. Last year was another year of decreased fuel cost at the pump with diesel fuel, which powers a large majority of this fleet, averaging $2.31 per gallon for 2016 (EIA, 2017), down from the 2011 to 2014 four-year average of $3.89.

The fleet-wide average efficiency for these fleets reached 7.11 mpg in 2016, a 1% increase over the same fleet in 2015, a tenth consecutive year mpg improved. But, after a 3% improvement in the fleet-wide average last year, it decreased to only 1% in 2016.  The report outlines the reasons for the decline in improvement.  Still, the 19 fleets operating 71,124 trucks saved $499,265,226 in 2016 compared to the national average of all trucks on the road.

Maybe the most significant part of the report is that data for most of the technologies is compared to the EPA’s forecast for technology adoption provided in the Regulatory Impact Analysis of their final Greenhouse Gas Phase 2 rule.  This provides unique 30 year adoption curves for such technologies as idle reduction solutions, tire pressure systems, automated manual transmissions, 6x2 axles, low rolling resistance tires and tractor and trailer aerodynamics.

 Three documents are provided: the full report, easy to cut and paste collection of key graphics and a data document and benchmarking tool.
