With more than 70,000 delivery vehicles worldwide, traveling in excess of 3 billion miles per year, fuel efficiency is always on their minds at UPS. And while the company has toyed with natural gas, fuel cells and other technologies to improve efficiency, the company recently announced a seemingly low-tech plan to launch a line of trucks with plastic bodies instead of conventional aluminum paneling.
The decrease in weight (1000 lbs.) will permit a smaller diesel engine to be employed, and should reduce total fuel usage by about 40% A fleetwide rollout of this "technology" would save more than 84 million gallons of fuel.
