The new Kenworth T680 tractor model has received U.S. Environmental Protection Agency (EPA) SmartWay designation.

“Kenworth is proud that the Kenworth T680 has earned the prestigious EPA SmartWay designation,” said Gary Moore, Kenworth general manager & Paccar vice president. “As our most aerodynamic truck ever, we look forward to providing customers with enhanced fuel efficiency and reduced emissions with the new T680.”

The T680 features an aerodynamic body with 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. It comes standard with the 12.9L Paccar MX engine, offering 380 to 485 hp. and torque up to 1,750 lbs.-ft.

According to Kenworth, EPA SmartWay designated tractors are intended for use with 53-ft., 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.
