The Kenworth T680's sleek, aerodynamic body benefits from 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. This power range, combined with excellent fuel efficiency, high reliability and durability, lightweight design, and low cost of ownership, makes the PACCAR MX engine an ideal choice for Kenworth customers operating in various applications, including over-the-road and pickup and delivery.

Kenworth's industry-leading, aerodynamic line-up now includes three on-highway vehicles with the valued EPA SmartWay Designation - the Kenworth T660, Kenworth T680 and Kenworth T700. In addition to the aerodynamic benefits, each model features a different cab width to provide customers with an excellent selection to meet their specific applications requirements. Cab width for the T660, T680 and T700, respectively, is 1.9, 2.1 and 2.3 meters.

According to the 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.
