General Motors has developed a medium-duty chassis cab truck powered by a hydrogen fuel cell powertrain for commercial buyers that the company is also pitching to the U.S. military, the company announced.

GM will show the truck, which is known as the Silent Utility Rover Universal Superstructure (SURUS), at the fall meeting of the Association of the United States Army (AUSA) from Oct. 9 to 11.

The truck uses GM's Hydrotec fuel cell system and offers autonomous capability, according to GM. It has been developed to handle large payloads over longer distances. The vehicle is a hydrogen-electric hybrid using GM's second-generation fuel cell system, two electric drive units, and lithium-ion battery pack that enables more than 400 miles of range.

Commerical applications include use as a utility truck, mobile and emergency backup power generation, flexible cargo delivery systems, commercial freight, and medium-duty uses.

The vehicle also uses four-wheel steering, advanced propulsion power electronics, GM truck chassis components, and an advanced suspension.

The SURUS commercial platform was developed with the help of research from GM's joint testing project with the U.S. Army of its hydrogen-powered Chevrolet Colorado ZH2.

GM will continue testing the SURUS truck through the spring of 2018.
