2013 Fleet Study: First Annual Update Real Fleets. Real Experience. 4
Details Fleet Study OTR Tractors and 53 Trailers 60 techs & prac3ces 10 Fleets; 41k tractors & 125k trailers 2012 4.5b miles & 673m gals of fuel 109,306 miles/truck/year 3.1:1 trailer to tractor ra3o Findings Ten Fleets versus Business as Usual 57,760,101 gallons saved/yr or 1,416 gal/truck/yr $231,040,404 saved/yr or $5,665/truck/yr 5
Technology Selec3on 60 technologies Available Purchased From other studies ~3 year Payback Cost of technology not a factor Highest cost = Automated transmissions, APUs, major Aero Lowest = Lower speed, Engine parameters, Wheel covers 6

Move from manual to Automated Manual transmissions Use of doubles or triples trailers Cutdown mudflap width Tire pressure inflation - trailer Downsize engine (e.g. 15L - 13L) Wide based tires - tractors Mechanical Turbo- compounding Predictive cruise control Wide based tires - trailers Flyswatter mudflaps - trailer Flyswatter mudflaps - tractor Use of clutched air compressor Truck Stop Electrification Capable Remove or relocate any trailer drag parts? (name them) Battery APUs Move from 6x4 to 4x2 tractor specs Spec dead (6x2) axles Tire pressure monitoring - trailer Wheel covers - tractors Fast ramp to 100% Slow ramp to 100% Ramping at <100% Started and stopped Never purchased Each Fleet is represented as a column showing adop3on differences.
