Purchasers of certain Kenworth medium-duty diesel-electric hybrid tractors in the United States are now eligible for a tax credit of $9,000, the maximum available, under a qualified hybrid motor vehicle credit offered by the federal government.


The U.S. Department of Treasury and Internal Revenue Service recently certified the tax credit eligibility of Kenworth T370 Class 7 hybrid tractors when equipped with a Paccar PX-6 engine and an Eaton(R) diesel-electric hybrid power system. The credit applies to Kenworth hybrid tractors built this year. The T370 hybrid tractor is available up to 55,000-pound GCW, for local haul applications, including beverage, general freight, and grocery distribution.

Earlier this year, Kenworth's T370 and T270 hybrid trucks for pickup and delivery and utility applications received certification from the U.S. Department of Treasury and Internal Revenue Service for tax credits. The T370 qualified for a $12,000 credit, the maximum for Class 7 hybrid trucks. The T270 qualified for a $6,000 credit, the maximum for Class 6 hybrid trucks.

The Kenworth hybrids feature a Paccar PX-6 engine, integral transmission-mounted motor/generator, frame-mounted 340-volt battery pack, and dedicated power management system. Electricity generated through regenerative braking is stored and used for acceleration, assisting the diesel engine. The hybrid system is monitored through an in-dash display. As the power requirements for different driving conditions change, the screen constantly updates the driver on system status.
