Semi Truck Fuel Economy Reaches 12 MPG
“Tall” gearing and a large engine are giving an expedited freight hauler the high fuel economy he sought, even if most factory engineers won’t approve his spec’ing requests.
Tom Buchwald, who heads Expedel Services out of Shelbyville, Tenn., recently purchased a Class 7 straight truck with an engine and transmission about twice the size of what such trucks usually have.
He says it’s getting about 12 mpg in highway service, compared to 6 or 7 mpg with a typical medium-duty truck whose powertrain components are much smaller and whose engine races to keep up speed.
