Executive Reports

The NACFE is proud to announce the publication of its first Freight Efficiency Executive Report. These reports are provided to help accelerate the adoption of freight efficiency products, technologies and practices. They describe in five or so pages the concept, the best use of the product or practice, for instance the duty cycle and vocational applicability, its technical details, economics, some real world applicability and other important information to help fleets determine if this is something they should pursue. The Executive Report offers a balanced investigation of the feature providing both the improved performance and economic considerations, while being sure to identify adverse consequences of its use. Once published, the industry is asked to comment on the report and even suggest further areas of investigation. This might include more detailed study in a particular aspect of the topic or consulting / collaboration around the idea. The first report details the opportunity of adopting 6×2 dead axle tandems on tractors. Other reports will be coming.

Preventative Maintenance

In this report, the effects of proper preventative maintenance to enable lower fuel consumption will be discussed. Operational functions such as driving style, dispatch practices, road conditions, weather, and traffic all effect fuel economy. Consistent, effective vehicle maintenance can deliver big returns for many aspects of fleet costs including unexpected down time, higher repair costs and fuel economy. An efficiently operating truck can help minimize the effects of all these variables.

Speed Limiters

The North American Council for Freight Efficiency has issued its third Executive Report.  This report discusses the advantages and issues to be considered when implementing a process to limit speeds on commercial trucks.  The power and associated fuel to propel a motor vehicle at highway speeds is significant and rises exponentially when driving faster.  This report is the result of interviews with some major fleets who have adopted a speed limiting strategy.

Wide Base Tires

The second Executive Report offered by the NACFE for use to improve freight efficiency is on wide base tires.  Wide base tires were originally developed decades ago to lower vehicle weight, cost and to simplify the tire management for fleets.  This technology turns 18 wheelers into 10 wheelers.  Through their development over the years they are proving to provide substantial fuel consumption reductions, along with the weight savings.  These two factors improve freight efficiency.  The first increasing the miles traveled per gallon of fuel and the second in providing for more freight to be hauled as cargo in the trailer.

6×2 (Dead Axle) Tractors

This report explores the pros and cons of fleet adoption of 6 X 2 tractors. These vehicles are equipped with a rear tandem axle that includes one drive axle and one non-driving axle. This tandem configuration is sometimes referred to as a tag tandem (non drive axle in the rearmost position) or pusher tandem (non-driving axle in the forward position of the tandem). Another term used is “dead axle tandem”, to reflect the presence of one non-driving axle. Although 6 X 2 tractors have been available for years, their volumes have been relatively low. Recently, however, there is increasing interest in this configuration due to potential fuel economy increases ranging from 2.5 to as much as 6%.
