Zero-emission step van passes durability testing phase

May 16, 2013

AMP Holding, under the Workhorse brand, has announced that its all-electric medium-duty step van has completed durability testing at Transportation Research Center (TRC), an independent testing lab in East Liberty, OH.

TRC tested the vehicle under an accelerated testing protocol designed to determine the durability of the vehicle by simulating a 20-year service life. The testing ran for 4,000 miles during the Ohio winter from February to April, AMP said.

According to AMP, the tests included running 2,000 miles at curb weight and 2,000 miles fully loaded. Each durability cycle was just under 10 miles long, and consisted of traversing a series of resonance, chatter, and impact bumps, a series of moderate washboards, frame twists, and dips, inverted chuckholes, stopping and starting on a 20% brake slope, “lock-to-lock” figure-8 maneuvers, a short slalom course, and traversing gravel roads.

AMP’s all-electric incorporates a dual-motor system that produces 250 kw and accelerates the 19,500 GVW vehicle faster than the original factory-installed diesel engine, the company said. The system has a total energy storage system of 100 kwhr that can push the 1,000 cubic foot vehicle 100 miles on a single charge.

AMP plans to produce step vans and other vehicle types using the AMP Workhorse Custom Chassis plant in Union City, IN.
