What are you hauling with this beast?

This is NOT your average highway hauler. The 2026 Kenworth T680 is a meticulously engineered machine, built from the ground up for drivers who demand serious power, bleeding-edge efficiency, and a driving experience that puts them in complete control. If you live by the numbers and crave top-tier performance, this is the rig that checks all the boxes.

Let's break down the heart of this beast:

⚙️ Engine: The legendary PACCAR MX-15. This powerhouse is renowned for its robust construction and relentless delivery of torque.

🐎 Horsepower: A potent 525 HP ensures you have the muscle for any incline or overtaking maneuver.

💪 Torque: Experience the sheer force of 1850 lb-ft of torque. This is what gets you moving heavy loads with confidence and makes light work of steep grades.

But raw power needs intelligent management. Kenworth pairs this engine with a driver-favorite transmission that offers ultimate engagement and precision:

⚙️ Transmission: Eaton 13-Speed Manual. For the drivers who appreciate a tactile connection to their truck and the ability to precisely control power delivery. This is peak driver engagement.

Beyond the engine and gearbox, every aspect of the T680 is optimized for superior on-road performance and long-haul efficiency:

💨 Aerodynamic Design: The T680's sleek profile, including the 76-inch high-roof sleeper, is a testament to Kenworth's commitment to reducing drag. This translates directly into significant fuel savings, improving your operational costs and maximizing your profits mile after mile.

⛽️ Massive Fuel Capacity: Equipped with a substantial 240-gallon diesel tank, this truck is designed for extended range operations. Spend more time on the road and less time at the pump, boosting your productivity.

✅ California Compliant: Demonstrating that power and efficiency can coexist with environmental responsibility. This truck meets stringent emissions standards.
The driveline is engineered for exceptional load-carrying capabilities and highway cruising:

Axle Ratio: A smart 3.25 Rear Axle Ratio provides a perfect equilibrium. It offers robust pulling power when you need it most for heavy loads, while also ensuring efficient cruising speeds on the open highway, contributing to overall fuel economy.

The Synergy: This combination of a high-torque PACCAR engine, a responsive manual transmission, and a class-leading aerodynamic design means you get a truck that’s not only powerful but also remarkably efficient. It’s built to maximize your uptime, minimize your operational expenses, and deliver a superior driving experience on every journey.
