Kenworth's new T680 model has received the U.S. Environmental Protection Agency SmartWay Designation.

The Kenworth T680 features sculpted full-height roof, optimized bumper and hood, full-height side extenders, cab/sleeper-to-fairings closeout panels, chassis fairings extenders and flush-mounted lighting.

The model is standard with the 12.9-liter Paccar MX engine, which offers a range of 380 horsepower to 485 horsepower and torque up to 1,750 pound feet.

EPA SmartWay Designated tractors are intended for use with 53-foot, box van trailers that are also EPA SmartWay Designated. According to the EPA, a SmartWay tractor-trailer combination may reduce fuel consumption by as much as 18% at highway speeds. Fleets in-use savings will vary based on their specific operations and environment.

The EPA SmartWay Transport Partnership is a collaboration between the EPA and freight industry designed to improve energy efficiency and reduce emissions. To receive EPA SmartWay Designation, trucks must offer a full aerodynamic package, including integrated roof fairings, fuel tank side fairings, cab/sleeper side extenders, aerodynamic bumpers and aerodynamic mirrors, low rolling resistance tires, as well as options for reducing extended engine idling.
