Kenworth Truck Company has selected the Zimmerman Truck Lines to test the new Kenworth T680 trucks for the long-term reliability.
The trucks are powered by the new 12.9L PACCAR MX-13 engine that generates an output of about 500hp and 1,850lbft of torque.
Zimmerman Truck Lines chief operating officer Mark Zimmerman said along with driver satisfaction, the actual cost-per-mile is what drives our purchasing decision.
"Sale price, fuel mileage and resale value all play a factor, but the one thing we've always looked at and use as a gauge when purchasing trucks is what it costs us, per mile, for the life of the truck," Zimmerman added.
Along with the new T680 with PACCAR MX-13 engine and Eaton UltraShift PLUS transmission, Zimmerman has received the delivery of five new T660s in 2012.
