Kenworth Truck Company and Dunn Lumber, both Seattle-area companies, have teamed up to bring Kenworth’s first medium duty hybrid-electric truck into the U.S. market.
Kenworth’s goal for its new medium duty hybrid is to enhance fuel economy by up to 30 percent in start-and-stop applications, such as pickup and delivery and utility trucks. Kenworth is offering limited production of medium duty hybrid trucks for municipal fleets and utility companies this year with full-scale production expected to follow in 2008.
Dunn Lumber’s new Kenworth Class 7 hybrid, which can carry a payload of up to 16,000 pounds, features a PACCAR PX-6 240 hp engine, integral transmission-mounted motor/generator, frame-mounted 340-volt battery, and dedicated power management system.
The Dunn Lumber fleet includes four Kenworth T800 Class 8 trucks and six other Kenworth medium duty conventionals that run between 20,000 to 26,000 miles annually.
