New truck marks beginning of long-term strategic partnership

Daimler Trucks North America (DTNA) and Walmart have collaborated to build the first-ever hybrid electric Freightliner Cascadia.

This truck also marks the beginning of a long-term strategic partnership between DTNA and Walmart to develop innovative, green technologies.

Developed based on a Walmart spec’d truck, the 72-inch raised roof Detroit Diesel DD15-equipped Cascadia features a parallel hybrid system based on an electrically-driven second drive axle. The system uses advanced lithium-ion-based energy storage and advanced electronic control algorithms that were developed in collaboration with the Daimler Trucks Global Hybrid Center in Japan.

With this advanced hybrid technology, the conventional drivetrain remains completely intact, allowing for high system reliability from the very beginning. In addition, initial assessments of fuel efficiency further indicate the potential of this technology.

“Starting with our advanced wind tunnel testing facility, DTNA has long been dedicated to developing the industry’s most efficient and environmentally-friendly technologies, and this new Cascadia marks the next evolution in hybrid electric solutions for heavy-duty vehicles,” said Wilfried Achenbach, senior vice president, engineering and technology for Daimler Trucks North America.

Long-time customer Walmart will work closely with DTNA engineers to create new products that will ultimately serve as a roadmap to future innovations.

“Walmart is partnering with our suppliers like Daimler Trucks North America to develop technologies that will improve the efficiency and lessen the impact of our operations. These partnerships help to prove out these technologies and speed up the time to market,” said Chris Sultemeier, senior vice president of transportation for Walmart. “We look forward to working with DTNA on this and other projects.”

DTNA already offers products powered by alternative technologies, including the Freightliner Business Class M2 106 Hybrid, and the Freightliner Business Class M2 112 natural gas lineup.
