Slower Drivers are Profitable for your Business

Fuel Mileage

You may know excessive speeding can dramatically reduce fuel economy, but few of us have bothered to learn just how much it costs. Following is some useful and startling information compiled from DOE data.

The DOE calculation
Unfortunately, it's true. Your vehicle's gas mileage decreases once it gets past its optimal speed. For most vehicles, this is around 55 mph. This means that every time you go over this speed, you're essentially wasting fuel and money.  You'd be surprised to learn that a slight decrease in your highway driving speed could significantly reduce your fuel consumption, while only adding a few minutes to the travel time.

How much?
According to studies backed by the DOE, the average vehicle will be at its advertised peak efficiency MPG at 55 mph. But as the speed increases you lose up to 28% of efficiency when traveling at highway speeds!  The data:
- 3% less efficient at 60 mph

- 8% less efficient at 65 mph
- 17% less efficient at 70 mph
- 23% less efficient at 75 mph
- 28% less efficient at 80 mph


EZ Fleet's Speed Alerts.

EZfleet's GPS system has two types of speed alerts.   One is a top end “threshold” alert.   Set the threshold at, for example, 70 mph and if a driver exceeds that alert you can be notified they exceeded that speed (or get a daily report of all violations).   The other alert is “posted speed” alert.    Set this alert to be triggered if a driver exceeds, for example, 12 mph over ANY posted speed limit on any road. Alerts can be sent to your email or phone but you may want to simply have a daily or weekly report sent to you showing you all violations.  (see attached report) 

Use these alerts or reports to coach your drivers.  Provide incentives or gift card to those with the least violations.   Then watch your fuel bill plummet!
