Start with the most highly evolved aerodynamic long-haul tractor Kenworth has ever engineered. Optimize the powertrain with an efficient, fully-integrated solution from PACCAR. Incorporate easier-to-service, longer-lived components for maximum uptime. Add smart technology that makes driving more intuitive, safer, less fatiguing. And include a world-class cabin reminiscent of the finest automobiles. Welcome to the Kenworth T680.



PROFIT-TUNED PERFORMANCE

The sleek new exterior of the T680 incorporates innovative aerodynamic design features meant to squeeze every possible mile from every gallon. Offering you up to 7 percent in fuel savings* from day one.

*Based on similarly spec’d T680 classic model. Fuel savings dependent on spec and application.

CUTTING EDGE EXTERIOR STYLING

Wind-cheating features begin up-front with a narrower hood and grille design that cuts neatly through the air. A-pillar turning vanes create less wake next to side windows and smooths airflow around the cab. Integrated front air dams, redesigned chassis fairings, and optional 28-inch side extenders work in tandem to keep airflow tight to the truck. Tandem axle fairings combine with new wind-slick wheel covers to reduce turbulence around the rear wheels and on to the trailer.

FUEL-SAVING INTELLIGENCE

A state-of-the-art, fully-optimized PACCAR powertrain together with innovative technologies such as Predictive Cruise Control, Predictive Neutral Coast and driver shift aids deliver unrivalled fuel-saving performance – automatically.

NEXT GEN EXTERIOR LIGHTING

Headlamp choices:
  • New best-in-class LED headlamps boost lighting efficiency, offering a wider pattern and whiter lighting for better visibility. Signature LED daytime running lights add a signature Kenworth look.
  • Halogen headlamps flow with the hood and integrate daytime running lights and an amber turn signal.

New side turn indicators: An unmistakable 17.3”-long LED side turn indicator, mounted to the trailing edge of the hood, increases visibility for surrounding traffic.
