Helping design and engineering professionals discover, evaluate and specify technologies and processes that shorten the design cycle and enable success.
The Walmart Advanced Vehicle Experience (WAVE) is a concept tractor/trailer combo was designed by the retailer, Peterbilt, Roush Engineering, Great Dane Trailers, and Capstone Turbine. The oddly shaped cab is 20% more aerodynamic than a traditional truck, and it's powered by a Capstone micro-turbine hybrid electric drivetrain that can run on diesel, biodiesel, and compressed natural gas. In urban areas, the trucks can run on electric power alone.
According to the company, designers used computational fluid dynamics (CFD) analysis to optimize the cab's unique styling. The cab sits over the engine and the wheelbase has been shortened, which reduces weight and improves maneuverability.
Walmart operates a fleet of around 6,000 trucks, and announced in 2005 that it wanted to double fleet efficient by 2015. According to the company, it has already achieved an 84% improvement.
It also has a 53-ft. carbon fiber trailer, which the company says is an industry first. The trailer has a convex nose and includes one-piece carbon fiber panels that are among the largest ever made. The design has shaved nearly 4,000 lbs. of weight from the trailer.
The company showcased the truck at the Mid-America Trucking Show (MATS) last month.
