T680 Technology
The new T680 is built around the driver experience — both inside the cab and out on the road. Its advanced digital technologies help drivers stay informed, comfortable, connected, and focused.
15-inch Digital Driver Display: At the center of the dash is an industry-leading 15-inch digital display. The screen provides vehicle health information, navigation, trip data, safety system alerts, and more. Drivers can personalize layouts and quickly access the information that’s most important to them.
SmartWheel: Kenworth’s upgraded SmartWheel places vehicle controls directly at the driver’s fingertips. Buttons for cruise settings, adaptive cruise functions, phone connectivity, audio adjustments, trip management, and digital display navigation allow drivers to keep their eyes on the road while still operating essential systems.
TruckTech+ Remote Diagnostics: TruckTech+ helps drivers proactively monitor vehicle health and communicate service information to fleet managers and Kenworth dealerships in real time. Standard on the T680 Next Gen, this system helps identify issues faster and streamline service coordination with ease.
Advanced Driver Assistance Systems (ADAS): The T680 Next Gen offers a suite of safety technologies designed to improve driver awareness during long hauls. Safety features include collision mitigation, lane assist, and predictive cruise control, among many others. These systems all work together to provide a safer, more confident overall driving experience.
DigitalVision Mirrors: Replacing traditional side-view mirrors, these smart mirrors with an advanced camera system provide a clear 360-degree view and awareness around the truck. Plus, the interior-mounted displays keep the driver’s eyes closer to the road compared to the normal field of vision. The benefits of DigitalVision Mirrors include reduced blind spots, night vision capability, hydrophobic lenses, and much more.
