Aerodynamics
A significant factor affecting fuel use is aerodynamic resistance, commonly known as drag. Studies by the Rocky Mountain Institute and others have shown that drag is a large factor in fuel use, and that a reduction in drag will reduce fuel consumption at both urban and highway speeds. For tractor-trailer combinations, about 70% of drag is due to the trailer.

Many OEM and aftermarket manufacturers are selling these devices today. For a look at the experience of BC fleets piloting some of these technologies, see Fleet Experiences.

Also see a May 2003 article on highlights of a US Lawrence Livermore Labs analysis on the impact of drag on fuel efficiency in large tractor-trailer combinations: “Reducing Aerodynamic Drag”. A recent Freight Wing study on trailer fairings showed that this aerodynamic feature could offer a 6.4% savings in fuel consumption and pay for itself in 1.1 to 2.2 years. |

Some of the devices heavy-duty commercial trucking can consider to reduce drag include:
E3 Fleet PartnersThe E3 Fleet program reflects the commitment and expertise of many people, including some of the country’s most innovative fleet managers. All have a common passion – to see Canada’s fleets take a cleaner, green road to the future. The Fraser Basin Council launched E3 Fleet in 2006 in cooperation with Climate Change Central (Alberta) and Fleet Challenge. Since October 2016, the program has been managed by Fleet Challenge Inc. The E3 Fleet Charter members were also pivotal to its success: Auto-Gas Propane, BC Hydro, BC Ministry of Environment, City of Coquitlam, Corporation of Delta, Enbridge, City of Hamilton, Hydro One, City of Kelowna, Township of Langley, District of Maple Ridge, City of North Vancouver, Novex Couriers, City of Prince George, District of Saanich, University of BC and Municipality of Whistler. We’ve enjoyed the journey so far, and it’s only just begun. Join us! |
