KIRKLAND, Wash. — A new Kenworth T370 Class 7 diesel-electric hybrid tractor for local haul applications, including beverage, general freight, and grocery distribution, has officially rolled off the line.

Kenworth’s goal for the T370 hybrid tractor is to improve fuel economy by up to 25% in local haul applications. The tractor will be available in various wheelbases, starting as short as 153 inches. The new Kenworth hybrid tractor will be a featured participant during the Oct. 16 Ride and Drive event at the annual Hybrid Truck Users Forum (HTUF) in South Bend, Ind.

The Kenworth T370 tractor is powered by the PACCAR PX-6 engine and features an integral transmission-mounted motor/generator, a frame-mounted 340-volt battery pack, and a dedicated power management system. Advanced powertrain controls are designed to monitor driving conditions and automatically select the ideal power mode, smoothly switching among electric only, combined diesel and electric, and diesel only power modes. Electricity generated through regenerative braking is stored and used for acceleration, assisting the diesel engine. The hybrid system is monitored through a dash display. As the power requirements for different driving conditions change, the screen constantly updates the driver on system status, the company said.
