Why should I consider onboard technology for my fleet?
Fuel Economy:
"The driver is arguably the principal variable in fuel mileage. There is as much as a 35 percent different between the most proficient and least capable drivers" - The Fleet Manager's Guide to Fuel Economy, The Technology and Maintenance Council of the American Trucking Association.
Engine idle:
Average truck wastes 2196 gallons per year idling (Argonne National Lab)
Minimium 1 gallon per hour idle, without A/C or other engine load
Speed:
For every 1 MPH increase over 55 MPH, fuel consumption increases 2.2%
7.5 MPH at 55 MPH drops to 6.6 MPG at 65 MPH.
Rapid accelerations and decelerations:
Widely variable based on vehicle weight and driver aggressiveness, frequent and rapid braking wastes energy spent building the vehicle's momentum.

Emissions:
10 MPH speed reduction reduces diesel engine NOX emissions by 18%.
Idling by commercial trucks releases an estimated 10,000,000 tons of CO2, 50,000 tons of NOX, and 2,000 tons of particulates.
Vehicle Maintenance:
Increase in speed from 55 MPH to 65 MPH increases tire wear 5% to 16%, depending on weight.
Increase in speed from 55 MPH to 65 MPH decreases miles to engine overhaul by 10% to 15%.
Increase in speed from 55 MPH to 65 MPH increases oil consumption 15%.
Idling for 6 hours = 42 miles of engine wear.
