One of Kenworth Truck Co.’s new models received a government designation certifying its energy efficiency and reduced emissions, the original equipment manufacturer announced Aug. 5.

The U.S. Environmental Protection Agency collaborates with freight companies to reduce emissions as part of the SmartWay Transport Partnership. The Kenworth T680 Next Generation model met the requirements to receive a designation as part of the initiative.

“We’re proud that the Kenworth T680 Next Generation — our most aerodynamic truck ever — has earned the EPA SmartWay Designation,” Chief Engineer Joe Adams said in a statement.


The EPA SmartWay designation is only afforded to tractors that offer a full aerodynamic package, including integrated roof fairings, chassis fairings, cab/sleeper side extenders, aerodynamic bumpers and mirrors, low-rolling-resistance tires and idle reduction features.

Kenworth conducted aerodynamic simulations to develop each individual component of the truck model during the design process. The company also verified results through wind tunnel testing. The focus was on keeping airflow closer to the cab and reducing turbulence. The bumper directs air underneath the chassis and past the wheel openings, and the hood is 8 inches narrower than before. — Transport Topics
