Tests were performed to measure the differences in fuel consumption of a cross section of passenger vehicles and light trucks when traveling 55, 60 and 70 mph. A secondary objective was to determine the effect on fuel consumption of using the vehicles' air conditioners. Results showed that an average of eight percent more fuel was required when traveling 60 mph versus 55 mph, and an average of 22.5 percent more fuel was required at 70 mph versus 55 mph. Using the air conditioner required an additional 4.5 percent of fuel, at 55 mph, when compared to a windows closed/air conditioner off configuration.
