Chevrolet is entering the silent service.
The automaker has built a hydrogen-powered truck for the U.S. Army that generates its own electricity with an onboard fuel cell. The heavily-modified Chevrolet Colorado-based rig is powered by a 174-horsepower electric motor that can drive all four wheels while making hardly any noise and keeping a low thermal profile compared to an internal combustion engine.
Hydrogen tanks and a small battery are installed where the bed of the Colorado would normally be, along with a power-take-off unit that provides electricity for equipment in the field. Meanwhile, water emissions produced by the fuel cell's operation can be collected and used by troops for drinking, or keeping that mean bodywork clean in the driest of regions.
With its stealthy characteristics, lifted body, 37-inch tires, and an extreme off-road suspension, the ZH2 is envisioned as more as a patrol and reconnaissance vehicle than a replacement for a general purpose vehicle like the Humvee.
