Kenworth to develop ‘SuperTruck’

Kenworth, PACCAR Technical Centre and DAF Trucks will be collaborating on a highly efficient, $10 million SuperTruck project.

The SuperTruck 2 program is funded by the US Department of Energy (DOE) and aims to develop important advancements in Class 8 truck aerodynamics, engine and powertrain efficiencies.

The project’s target goals include the demonstration of greater than 100 per cent improvement in freight efficiency over 2009 equivalent product, and achieving 55 per cent in engine brake thermal efficiency.

The SuperTruck will be based on a Kenworth T680 with the 76-inch sleeper and the fuel-efficient PACCAR MX engine.

“The US 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,” said 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 heavy-duty trucks.

Up to US$12 million ($15 million) in additional funding could be awarded for the Kenworth T680 and PACCAR MX engine project over the next three years, subject to annual appropriations by Congress, which has reportedly been very supportive of the SuperTruck II initiative.
