Designed to meet the most demanding off-highway and severe-service applications, the Kenworth C580 blends the proven durability of the C500 chassis with the modern comfort, technology, and integration of Kenworth’s latest cab platform. Production of the C580 is scheduled to begin January 2027, with the model fully replacing the C500 which sunsets in 2026.

The C580 is available in single- or twin-steer axle configurations, with front-drive axle options enabling 4×4, 6×6, 8×8, and 10×10 configurations. High-capacity axle ratings support up to 44,000 pounds on twin steer axles and up to 165,000 pounds on tandem rear axles.
In North America, the C580 is standard with EPA compliant Cummins X15 engines, with ratings up to 605 horsepower and 2,050 lb.-ft. of torque. Additional Cummins X15 engines are available with several levels of Euro emissions compliance for export to international markets. The C580 features Kenworth’s full suite of transmission offerings including manual transmissions, Allison 4000 and 6000 Series automatics and for the first time in the extreme-duty segment, the advanced Eaton Endurant XD Pro automated transmission.

The C580 features a large 1,780-square-inch cooling module and is designed to handle high-horsepower operation in stationary, high-altitude, and extreme-heat environments. Full-length parent frame rails extend to the front of the chassis and support FEPTO capability for specialized vocational applications. Standard dual 13-inch cowl-mounted ERA air cleaners offer high performance, ease of service, and classic Kenworth styling.
Designed with durability in mind, the C580 features abrasion resistant double-wrapped exterior wiring harnesses, a sheet metal hood and fenders, robust five-piece crossmembers, and enhanced serviceability and component access to support body installations. Common electrical architecture with other Kenworth vocational models allows for seamless integration of power takeoffs, auxiliary lighting, remote throttle controls, and body-specific functionality.
