Kenworth Launches C580 Heavy-Haul Successor to C500 in 2027

Key Details Kenworth unveiled the C580 heavy-haul tractor on March 3 at CONEXPO-CON/AGG in Las Vegas. Production begins January 2027, fully replacing the C500 model which sunsets in 2026 after 54 years in service. What's New The C580 pairs the proven C500 severe-duty chassis with Kenworth's latest cab platform. Drivers get a larger windshield, optimized hood, wider seat spacing, and a customizable 15-inch digital display for safer, more efficient operation. Configuration Options The truck comes in single or twin-steer axle setups with front-drive options ranging from 4x4 to 10x10. Twin-steer axles handle up to 44,000 pounds while tandem rear axles support up to 165,000 pounds, enabling gross combination weights up to 1 million pounds. Power and Emissions Standard EPA-compliant Cummins X15 engines deliver up to 605 horsepower and 2,050 pound-feet of torque. The C580 supports manual, Allison 4000/6000 Series automatic, and Eaton Endurant XD Pro automated transmissions to meet 2027 EPA nitrogen oxide requirements. Why It Matters This modernization positions Kenworth to meet stricter emissions standards while maintaining heavy-haul capability that defines vocational trucking.
