Kenworth C580 Replaces Legendary C500 for Extreme-Duty Hauling

Key Details Kenworth unveiled its new C580 extreme-duty vocational truck at ConExpo in Las Vegas on March 3, marking the successor to the iconic C500 that has dominated severe-service applications for over 50 years. Production of the C580 is scheduled to begin in January 2027, with the C500 being phased out in 2026. Capabilities The new C580 can handle gross combination weights up to one million pounds and offers flexible drivetrain configurations including 4x4, 6x6, 8x8, and 10x10 options. It features single or twin-steer front axles, with twin steers supporting up to 44,000 pounds and tandem rear axles rated for 165,000 pounds. Why It Matters Kenworth remains the only OEM serving the extreme-duty off-highway segment, and the C580 honors the C500's legacy while delivering modern technology and driver-focused features. The original C500 earned its reputation operating in Arctic oilfields, Southeast Asian logging operations, mining sites, and Amazon heavy-haul applications. The new model will continue this tradition with enhanced capability and contemporary engineering.
