Daimler, Walmart roll out hybrid Cascadia

PORTLAND, Ore. — Daimler Trucks North America LLC (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, the companies say.

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 an 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. "Our customers look to us for advanced solutions in every application, and we will continue to deliver at every turn."
