U.S military multipurpose vehicle Humvee soon will be completed tours of duty, In lieu of the largest car manufacturers in the United States, General Motors (GM), began to consider a replacement.
Therefore, GM introduced the Chevrolet Colorado concept ZH2 scheduled to undergo a series of trials in 2017.
As reported by Jalopnik, actually the Chevrolet Colorado ZH2 based on Colorado regular double cabin truck extended and strengthened.
Now, Colorado ZH2 has dimensions of 198 cm high and 203 cm wide, with tires measuring 37 inches which helps special suspension performance.
Also, the Chevrolet Colorado ZH2 planned to bring hydrogen-fueled engines are expected to assist in military operations.
The toughness of Chevrolet Colorado ZH2 engine will be tested the ability to be able to walk quietly as possible and reduce the signs of heat.
Therefore, this Humvee replacement candidate will also wear an electric engine in order to reduce noise and fuel consumption.
Chevrolet Colorado ZH2 also carries a tool called exportable Power Take-Off (EPTO), which serves to remove energy from the car and can be used for other purposes such as being a generator
The Colorado ZH2 is a demonstration vehicle that will be tested by the U.S. Army to evaluate the effectiveness of a hydrogen fuel cell-powered off-road vehicle in mission setting. Chevrolet along with TARDEC (Tank Automotive Research, Development and Engineering Center) will begin testing the Colorado ZH2 in early 2017.
Proprietary chassis designed, engineered and tested by Chevrolet
The chassis was designed and engineered for off-road use. It starts with 37-inch BF Goodrich tires mounted to 17-inch beadlock wheels. Power is transferred from the 93 kW fuel cell system to the 132-kW electric motor, which produces 236 lb.-ft. of instantaneous torque. That torque is then delivered to the transfer case and a 4-wheel drive system with front- and rear- electronic locking differentials.
Off-road performance is further enabled by proprietary damper technology that provides body control for trail running and expanded wheel travel for rock crawling. Technical details about the dampers will be released later.
Calibration testing and validation are currently underway, and the Colorado ZH2 is expected to be a truly capable off-road vehicle featuring:
12 inches of ground clearance
48-degree approach angle and 39-degree departure angle
Top speed above 60 mph
Ability to ascend, descend and restart on 40 percent grade
20 percent side slope capability
Other ZH2 specifications include:
6:1 gear ratio
6,038 lbs. curb weight (estimated)
7,338 lbs. GVWR (estimated)
133.5 in. wheelbase
67.4 in. track width
