Conventional wisdom has it that driving too fast on the highway uses more fuel. But fleet operators don’t base decisions on conventional wisdom. General statistics provided by the government say that aggressive driving can lower highway gas mileage by as much as 33% and that driving above 50 miles per hour brings loss of fuel efficiency. But since each fleet is unique, smart fleet managers demand specifics.
Enter the Department of Energy’s easy to use fuel economy calculator, which puts concrete numbers to the conventional wisdom, shedding light on just how much you can save by making sure your fleet operates at a safe and efficient highway speed.
The calculator, at fueleconomy.gov, walks you through a few simple steps to determine just how much additional fuel your vehicles burn when driving at a higher rate of speed. By selecting the year, make, model, and engine specs of your vehicle, and then entering the type of fuel you use, average cost of fuel in your area, and your typical highway driving speed, you get a diagnosis specific to your fleet.
You’ll take away data on how much fuel your vehicles burn for each 100 miles driven at speeds ranging from 50 to 80 miles per hour. The calculator also provides the fuel cost per gallon at each of those speeds, as well as a chart detailing the savings in dollars per gallon, dollars per 100 miles, and the savings per extra minute of travel when you slow down 5, 10 or 15 miles per hour.
