Once the truck returns, hit group engineers remove it from the back of the cab, and place it on scales to be weighed.
Extremely sensitive scales measure the weight of the fuel left in the tank for an accurate fuel economy measurement.
Navistar President Bill Kozek personally signed off on getting a brand new LT tractor into the pit group fuel test.
Each truck is fitted with a 32-gallon fuel tank mounted behind the cab for the 52 mile test run.
Navistar chief performance engineer Aaron Peterson was also sent down to Chattanooga make sure the new LT tractor was ready to go.
US Xpress Senior Vice President, Maintenance, Gerry Mead, is particularly excited to see his company's brand-new next-generation Freightliner Cascadia tractor perform in the fuel test.
