Series Hybrid Peterbilt with Capstone Turbine, Parker Hannifin Motors
A Walmart truck with a series hybrid electric drive is to be shown by development partner Great Dane Trailers at the Mid-America Trucking Show in Louisville this week.
In addition to the carbon fiber Great Dane trailer, the Wave truck – for Walmart Advanced Vehicle Experience – features a Capstone Microturbine (diesel-fueled) and a PMAC permanent magnet AC traction motor from Parker Hannifin. The truck has lithium ion batteries.
Walmart trucks serve more than 4,800 U.S. locations. The retailer wants to double its fleet efficiency by 2015 (compared to 2005).
“We’re already 80% of the way there. Since 2007, we’ve delivered 658 million more cases while driving 298 million fewer miles,” the company says.
Details at MATS on Wednesday Evening
“But the key to continued improvement is through technology,” Walmart says on its fuel efficiency blog. “We need to use the most efficient equipment available – and we need to pursue and test the technologies of tomorrow.”
The Wave truck, Walmart says, “combines aerodynamic, mictroturbine-hybrid powertrain, electrification, and advanced control systems all in one vehicle.”
Like the concept cars in the auto shows, this prototype will evolve before it’s ready for the road,” Walmart notes. “In the meantime, Walmart is using existing technology to phase in more than 1,000 new 2014 tractors that are about 12% more efficient than current models and are projected to provide approximately $40 million in savings.
In addition to superior aerodynamics, a carbon composite Great Dane trailer for Walmart would save about 4,000 pounds. Walmart plans to provide further Wave truck details at a MATS 2014 press event on Wednesday evening.
MATS 2014 runs March 27-29 at the Kentucky Exposition Center in Louisville.
