GPS FLEET TRACKING & VEHICLE LIFE FACTORS TrackNet GPS Fleet Tracking Systems Gives You The Tools To Deal With Downtime and After Hours Usage!
Argonne National Laboratories, part of the US Department of Energy, conducted a study on the aggregate effects of excessive engine idling and speeding as part of overall vehicle operational costs:
ENGINE IDLE EFFECTS
Running a vehicle at idle speed dramatically reduces engine life; 60 minutes of idling is equivalent to between 80 and 120 minutes of driving time. The resulting loss of fuel economy from excessive idling can add up to 800 gallons of fuel annually for the average truck. On average an idling vehicle burns between 1.6 and 2.4 gallons of gas. (Since 2002, we have helped our customers learn that their vehicles average between 1 to 2 hours PER DAY of unnecessary idling! That is 2 to 4 gallons of gas saved per day!)
Ideal driving speed for the average truck is 50-55 mph; the power required to increase speed multiplies dramatically:
73% more horsepower to cruise at 60 mph
159% more horsepower to cruise at 70 mph
Each mile per hour above 50 mph increases fuel consumption by one-and-one-half (1½) percent. A truck, which averages 8 mpg at 50 mph, will average 6.8 mpg at 60 mph.
EFFECT ON TIRES
Sustained speeds raise tire temperatures above the critical level, causing strength and wear properties to deteriorate rapidly. Tire wear will almost double at road speeds of 70 mph or greater.
Gears, bearings, clutches, suspension and drive trains wear much faster at higher speeds. Increasing speed from 50 mph to 60 mph increases maintenance cost by 38%. Increasing the speed to 70 mph increases the cost by 80%.
Approximate stopping distances, factoring in the reaction time for the average person driving a 2-axle truck, are listed below:
50 mph – 275 feet (.92 football fields)
60 mph – 375 feet (1.25 football fields)
70 mph – 500 feet (1.67 football fields)
At 70 mph, stopping distance is 63% greater than at 50 mph. Even in daylight, higher speeds will significantly increase accident probabilities.
Measuring and Controlling Fleet “Soft Costs” Can Save You Big Money!

“Soft costs are actually more significant than hard costs and addressing them can have a greater impact on the success of a fleet program, both directly and indirectly.”
Jim Frank, President; Wheels, Inc.
2006 Fleet Manager of the Year Award Ceremony
Every business needs accurate and quantifiable data to make profitable decisions and long-term plans. Measuring hard costs like fuel, vehicle purchases, equipment expenses, etc. is a well defined way fleet managers track their progress. But identifying soft costs such as the bottom line impact of fleet downtime and driver safety is just as important!.
Downtime Is Critical
One of the most important responsibilities in fleet management is ensuring the dependability and productivity of a company’s vehicles so that employees can effectively serve customers and produce revenue. Consequently, preventive vehicle maintenance is key. Lost business due to out-of-service vehicles can be a significant drain on your budget.
A company with a fleet of 20 vehicles can typically have one vehicle out of service for unscheduled repairs at least twice every month at an average cost of $750 a day (the cost may vary according to your industry). A simple 25% reduction in this unscheduled soft cost can result in an annual savings of nearly $5,000 based on the following formula:
