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


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.


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.


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.
