Kenworth T680 Heavy Truck

Feb. 16, 2021

The next generation Kenworth T680 Class 8 truck includes new aero bumper and hood, turning vanes, durable lower fairing extensions, chassis fairings, wheel well closeouts, 28-inch side extenders, tandem drive axle fairings, and wheel covers, among other features, all to keep the airflow closer to the cab and reduce drag-causing turbulence.

The Kenworth T680 heavy truck is standard with the Paccar MX-13 12.9-liter engine and Paccar powertrain that also offer strong fuel efficiency gains. The MX-13 engine features enhanced durability, reduced complexity, performance upgrades, increased downspeeding capability, and more effi­cient combustion. It is paired with the Paccar 12-speed transmission and Paccar 40K axles.

The cab features a new 15-inch, high-definition, fully Digital Display. 

Kenworth T680 Specifications: 

  • Kenworth Advanced Driver Assistance Systems (ADAS): ADAS includes Lane Keeping Assist and Torque Assisted Steering as options. Lane Keeping Assist uses camera input to identify when the truck is departing the lane. Torque Assisted Steering provides additional torque to the steering column, reducing driver fatigue. Also included are Adaptive Cruise Control, Lane Departure Warning, Collision Mitigation, and Side Object Detection. 
  • Bumper and Under-Truck Airflow Management: The aerodynamic bumper has an improved profile to direct air past the wheel openings. The unique air dam design guides and controls airflow under the chassis while providing protective coverage under the cooling module.
  • Hood: The aerodynamic hood includes a hood air vent for aero benefit, narrower grille, and high-visibility side turn indicators. The hood is available in two sizes: 125-inch BBC (standard) or 119-inch BBC (MX).
  • TruckTech Remote Diagnostics: The system provides engine health information to fleet managers and Kenworth dealers. The system diagnoses the issue and provides the recommended solution to the driver and fleet manager.
  • Lighting: Fully LED headlamps have a built-in infrared heater to clear ice and snow.
  • Wheelbase Reduction: Improved chassis packaging provides a shorter wheelbase and a reduced trailer gap of between 38 to 42 inches.
