Kenworth Truck Company on Thursday, June 21, announced that its new aerodynamic Kenworth model has received U.S. Environmental Protection Agency SmartWay designation. “As our most aerodynamic truck ever, we look forward to providing customers with enhanced fuel efficiency and reduced emissions with the new T680,” said Gary Moore, Kenworth general manager and Paccar vice president.
The T680’s sleek, aerodynamic body benefits from a 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 T680 is standard with the 12.9-liter Paccar MX engine, which offers a range of 380-hp to 485-hp and torque up to 1,750 lb-ft and is suited for over-the-road and pickup-and-delivery applications.
Kenworth’s aerodynamic lineup now includes three on-highway vehicles with EPA’s SmartWay designation – the T660, T680 and T700. In addition to the aerodynamic benefits, each model features a different cab width for specific applications requirements. Cab width for the T660, T680 and T700, respectively, is 1.9, 2.1 and 2.3 meters.
EPA SmartWay designated tractors are intended for use with 53-foot box van trailers that also are EPA SmartWay designated. According to EPA, a SmartWay tractor-trailer combination may reduce fuel consumption by as much as 18 percent at highway speeds. Fleets in-use savings will vary based on their specific operations and environment.
