Key Features and Updates
Paccar Powertrain
The Kenworth T680 is powered by PACCAR’s fully integrated powertrain, combining the fuel-efficient PACCAR MX engines, transmission, and drive axles. Made for reliability and performance, the 12.9-liter MX-13 delivers the horsepower and torque for heavy-duty jobs, while the lighter 10.8-liter MX-11 is ideal for lighter pickup and delivery work. “PACCAR powertrain components work together at lower engine RPMs — regardless of road speed, reducing friction and fuel consumption delivering all the power drivers need.” (Source)
Aerodynamics
Outside the cab, Kenworth worked to make the most aerodynamic truck in their model lineup. It features a highly sloped hood, standard dual Halogen headlights, and an optional panoramic windshield. Smarter exterior design elements, like the narrower hood and grille or chassis fairings, were added to reduce drag and improve the truck’s overall efficiency. Made of stamped aluminum panels, its shape was crafted to cut through air with minimal resistance to help significantly save on fuel. These enhancements were implemented to improve a driver’s visibility while contributing to the truck’s aerodynamics.
Idle Management System
Kenworth’s factory-installed, battery-based no-idle system helps long-haul fleets reduce idling, fuel use, and emissions in both hot and cold climates without compromising performance. Its split system provides more storage underneath the bunk, while features like automatic heating and A/C, onboard diagnostics, battery monitoring, and a digital LCD display give drivers better, reliable comfort and easy control.
Comfortability
Like every truck, the experience for the driver starts with the design of the cab. Kenworth gathered more than 800 professional truck drivers to get a hands-on evaluation of cab preferences and needs. Coupled with Kenworth’s high standards for interior finish and features, the T680 is truly a driver-centric truck. Its spacious cab and sleeper offer premium comfort after those long days on the road. And, there are multiple interior options to choose from – including Diamond and Vantage trim levels – tailored to fit every driver’s personal style and needs.
Control and Connectivity
In today’s world, connectivity is so important, especially on the road. High-definition mirrors, configurable gauges, and an intuitive dashboard create a comfortable, functional workspace. Features like adaptive cruise, predictive systems, and digital dashboards help drivers stay focused and connected. Plus, Kenworth’s Driver Performance Center offers real-time insights to track fuel, vehicle status, and system safety performance on the go.
NavPlus HD
NAV+ HD is Kenworth’s in-dash, 7-inch high-resolution display. Consider it a driver’s personal assistant: with a simple touch (or voice-command), you have direct access to a full range of valuable, driver-focused features. Some of which are truck-specific navigation, roadside assistance, vehicle data, hands-free calling, audio and entertainment controls, blind-spot camera inputs, and even the internet.
T680
The Kenworth T680 is more than a truck. It’s a smart investment in efficiency, reliability, and driver satisfaction. Built for jobs both small and large, this truck represents Kenworth’s commitment to the driver’s experience. With the T680, Kenworth has made a Class 8 truck that is perfectly suited for the driver.
