Kenworth launched the all-new C580 at CONEXPO-CON/AGG, marking its next generation of extreme-duty, off-highway vocational trucks. The C580 will enter production in January 2027, fully replacing the C500, which will be phased out in 2026.
“The Kenworth C580 marks a new era in extreme-duty performance, capable of hauling up to one million pounds gross combination weight,” said Kevin Haygood, assistant general manager for sales and marketing.
Designed to meet the most demanding off-highway and severe-service applications, the Kenworth C580 blends the durability of the C500 chassis with the modern comfort, technology, and integration of Kenworth’s latest cab platform.
Kenworth C580 specs
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.
A technology-forward cab
While engineered for extreme-duty applications, the C580 delivers modern comfort and technology offered in other Kenworth vocational models, including the T880. The C580’s new cab offers enhanced visibility, a larger windshield, optimized hood slope, and increased room between seats compared to its predecessor.
A customizable 15-inch digital display places all gauges and critical information clearly in view, supporting safer and more efficient operation. New heated LED headlamps are standard on the C580, enhancing driver safety in all conditions.
Advanced Driver Assistance Systems (ADAS) improve driver safety, while TruckTech+ Remote Diagnostics delivers real-time fleet insights into the usage and health of vehicles.
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.
Building on a long-standing platform
The C500, introduced in 1972, was widely used in mining, oilfield operations, logging, heavy equipment transport, and prime mover applications. Its reputation was built on handling heavy loads in challenging terrain, both in North America and internationally.
“These trucks have been to the Arctic in the oilfields; in Borneo hauling logs and coal; in Asia transporting massive mining equipment; and deep in the Amazon hauling transformers,” said Haygood. “They’ve gone where no other truck could go, and now the new C580 will do the same, handling the most demanding jobs on and off the road.”
