The tare weight of a typical combination truck can be reduced by as much as 10,000 pounds by using lightweight
materials and eliminating unnecessary components (12). Most trucks will not be able to achieve reductions this
large, in part because of the need for certain accessories or more durable components.We assume that trucks could
achieve a weight reduction of 3,000 lbs. while still maintaining desired durability and features. A 3,000-pound
reduction in vehicle weight improves fuel economy by approximately 0.11 mpg at 65 mph (12). This would reduce
fuel use by 296 gallons annually for a typical long-haul freight truck.

Vehicle mass is a critical variable in determining fuel consumption. While the exact relationship varies from one situation to another (truck configuration, relevant weight range, road surface/condition, tires, wind, speed, road vertical geometry, etc), the relationship is probably within the range of 0.02 to 0.06 km/L for every tonne of weight (tare weight or payload weight). For example, a typical heavy diesel truck probably decreases fuel consumption (increases km/L) by one to three percent for every decrease of one tonne.
