ArvinMeritor Hybrid Propulsion
Walmart will test in the Detroit area, this first of its kind dual-mode diesel-electric hybrid. The ArvinMeritor hybrid has both mechanical and electrical propulsion systems, which use the electric motor drive primarily for periods of high demand under low-speed, high-load operating conditions, such as accelerating from a stop.

In addition to its work at highway speeds, the engine also charges an onboard energy storage system, which provides power to the electric motor when demand is high. Energy that is generated during braking is captured and stored using regenerative braking.
