As part of its continued commitment to sustainability, UPS will be implementing a new fleet of UPS brown vans that are designed to allow for better fuel efficiency.

The new fleet of UPS brown vans will be made of composite materials -- materials that have been used in both the Boeing Dreamliner jet and the Tesla sports car -- that will replace the significant amount of metal typically used in the construction of the large square vehicles. By using composite material, the trucks will weigh 900 pounds less than the original vehicles, which will boost fuel efficiency by 40 percent. Currently, UPS plans to buy 150 of the composite-body trucks to test their durability, repair qualities and structural strengths, reports BrandChannel.
