Truck maker Kenworth announced plans to sunset several popular models in 2026.

On March 19, Kenworth announced its decision to discontinue production of legacy 1.9-meter cab Class 8 trucks in 2026, including Kenworth’s W900 (W900L and W900B models), T800W (wide-hood), and the C500.

The company said that the decision to discontinue production on these models is due to “evolving emissions regulations and component constraints as the industry moves forward with new, more efficient, and better integrated technologies and products.”

“We know these legacy Kenworth models are an integral part of our history here at Kenworth, which makes this decision a difficult but necessary one as we enter the next era of trucking,” said Kevin Haygood, Kenworth’s assistant general manager for sales and marketing. “As we transition to future products, we remain committed to honoring the spirit of these iconic trucks by delivering innovation, efficiency, and the same level of craftsmanship that our customers and drivers have trusted for generations.”

A final call for truck orders will be issued later this year, but dealers and customers are advised to place orders as soon as possible.

“To ensure a smooth transition, Kenworth is providing comprehensive support and guidance to dealers and customers. Kenworth’s W990 and T880 are well-positioned to continue Kenworth’s tradition of excellence, offering best-in-class driver comfort, efficiency, and reliability. Kenworth’s latest T880S, with the newly designed performance hood, offers high horsepower engines and increased cooling capacity. The T880S Performance Hood is compatible with large displacement engines including the Cummins X15, rated up to 605 hp and 2,050 lb.-ft. of torque, making it a viable option for T800W applications,” the company said in a news release.
