Kenworth T680 with PACCAR MX Engine to Participate in DOE SuperTruck II Project

Kenworth will work with the PACCAR Technical Center and DAF Trucks NV to improve Class 8 truck efficiency through aerodynamics, engine and powertrain improvements as part of the SuperTruck II project.

Kenworth announces that it will collaborate closely with the PACCAR Technical Center and DAF Trucks NV, a subsidiary of PACCAR, to develop important advancements in Class 8 truck aerodynamics, engine and powertrain efficiencies with $8 million in year-one funding provided by the Vehicle Technologies Office of U.S. Department of Energy (DOE) SuperTruck II program. Other partners include Eaton, National Renewable Energy Laboratory (NREL), Mississippi State University, and AVL.

The project will utilize the company’s on-highway flagship Kenworth T680 with the 76-in. sleeper and the fuel-efficient PACCAR MX engine. The project’s target goals include the demonstration of greater than 100% improvement in freight efficiency over 2009 equivalent product, and achieving 55% in engine brake thermal efficiency.

“The U.S. DOE SuperTruck II project is an excellent opportunity for Kenworth, the PACCAR Technical Center and DAF engineers, along with our partners, to explore significant modifications to aerodynamic design, while also developing key ways to further enhance the efficiency of the PACCAR MX engine and PACCAR powertrain,” says Mike Dozier, Kenworth General Manager and PACCAR Vice President. “This is an important program that can produce real-world results to benefit fleets and truck operators with even greater reductions in fuel usage and emissions in the future.”

PACCAR joins four other SuperTruck II teams working to develop such innovative technologies designed to more than double the freight efficiency of Class 8 trucks. Up to $12 million in additional funding could be awarded for the Kenworth T680 and PACCAR MX engine project over the next 3 years, subject to annual appropriations by Congress, which has been very supportive of the SuperTruck II initiative.

According to the DOE, trucks haul 80% of goods in the United States and use about 28 billion gallons of fuel per year. This accounts for approximately 22% of total transportation energy usage and presents a significant opportunity to increase efficiency and reduce cost for a key segment of the nation's transportation sector.
