Fleets operating 41,000 tractors and 130,000 trailers achieved fuel savings of $7,200 per year per truck by adopting a variety of new technologies, according to a new study released Wednesday by the North American Council for Freight Efficiency.

Since 2011 this group of fleets, manufacturers, government and nongovernment organizations has conducted its Annual Fuel Efficiency Benchmark Study, a report on 10 of the largest most innovative fleets in terms of using products to improve fuel efficiency.

The studied fleets, which represent 2.5% of all the trucks on the road, include regional and long haul carriers who haul dry goods and refrigerated cargo.

The new study revealed that the average purchased adoption rate of fuel-saving technologies has increased from 31% to 50% since 2003. As a result, these fleets are achieving fuel economy of 6.77 mpg on average, an 8% increase since 2011.

The study also looked at 66 fuel efficiency technologies in six categories: idle reduction, chassis, practices, tires/wheels, tractor aerodynamics and trailer aerodynamics. Fleets that participated in the study shared their implementation experiences and best practices for using the various technologies. The study offers insights for other fleets considering adding these products or practices in the future, said NACFE.

According to NACFE, fuel saving technologies and practices with high adoption rates include: full height roof air fairings, minimizing fifth wheel height, synthetic transmission oil, limiting speed and training drivers for fuel economy.

Technologies that are being used frequently by fleets, according to the study, include:

  • Tractor chassis skirts – partial; 40%, up from 27% in 2012
  • Fixed 5th wheel with minimum gap; 51%, up from 38% in 2012
  • Specified weight reduction on tractors; 54%, up from 44% in 2012
  • Specified weight reduction on trailers; 60%, up from 50% in 2012
  • Spec’ing dead axles; 14% up from 10%, in 2012
  • Move to automated transmissions; 20%, up from 0% in 2012

“The study is extremely valuable because it is based on technologies that are currently available and being used by fleets in their operations today. Real-world data shows that fleets are increasing their adoption rates of these technologies and seeing measurable improvements in fuel economy,” said Mike Roeth, NACFE executive director.

He said these technologies present an enormous opportunity for improved freight efficiency since there are about 1.5 million tractor-trailers on the road in North America, consuming 26 billion gallons of diesel fuel. For every 1% reduction in fuel use, 260 million gallons of fuel, or about $1 billion, per year are saved, according to Roeth.

“While all these technologies have costs associated with them, the fleets we studied saw a payback in three years,” Roeth. “We anticipate this payback will improve going forward as more fleets adopt these technologies. This should bring economies of scale to producing them and lower the initial purchase price.”

The full report is available on the NACFE website.

    So 6.77 mpg with all that....why do I get 7 with a few cheap engine mods....and that's with a 1996 fld120 12.7 with 4.11 rears and a 9 speed. ..

    Hauling liquid, I gross 78k loaded, then 32k empty on backhaul. I average 7.1 mpg with a 1990 pete 379 machanical cat 3406 turned up and a 15 sp. 390 rears on 24.5 rubber.
