[font size=3]Late last year, we got news that General Motors would work with the US Army to develop a hydrogen-fuel-cell-powered pickup truck. On Monday at an annual US Army association meeting, GM took the wraps off the beast, which the Army will test in Michigan over the next year.
The US Armys tank research center collaborated with GM to build the Chevy Colorado ZH₂, which has a reinforced body thats six-and-a-half feet tall and seven feet wide. The truck will chew up terrain with 37-inch tires and a special suspension built for off-road handling.
The ZH₂ has a single motor thats powered by a hydrogen fuel cell and a battery. The advantage of that hydrogen fuel cell is that the only byproduct is water, and the electricity-powered engine is quieter than a traditional combustion engine. It also gives off less heat, which GM said would help the car in stealth situations, where the Army would want to reduce acoustic and thermal signatures. According to Wired, the ZH₂s hydrogen fuel cell produces two gallons of water an hour.
Clearly, hydrogen supply issues arent stopping GM from building research vehicles. The Colorado ZH₂ follows GMs announcement of an unmanned undersea vehicle (UUV), which it built in partnership with the US Navy. That UUV is currently being tested in a pool for weeks if not months of endurance in underwater environments.

yet it produces power- and the fuel can be made anywhere there is water and electricity.
Not many superchargers off the main interstates. If it was battery only, the battery would have to weigh more than a ton. And one day that battery would end up in a landfill. And even if there were superchargers in the bush, imagine a few soldiers waiting around 45 minutes for a 75% charge- every ~200 miles.

(19,937 posts)Your list includes carburetor and distributor. What cars are sold today with a carburetor or a distributor? Today, fuel injectors and electronic ignition are the norm.
Yes, there will be routine maintenance which is eliminated, but there will still be necessary routine maintenance. Tires, brakes, shocks/struts, body work
There will even be maintenance necessary with an electric car which is not necessary with a conventional car, since, currently, storage batteries and fuel cell stacks both have limited lifespans when compared to a well-maintained internal combustion engine.
And just because the car is driven by an electric motor, or even expensive does not guarantee it is well made.

The magazine recently released its list of "Used Cars to Avoid Buying," and the 2014 BMW i3 was among the dishonorable mentions.
The 2012, 2013, and 2015 versions of the Tesla Model S all have "much-worse-than-average" reliability, according to the magazine.
Despite heaping praise on the Model S when it was new, Consumer Reports last year pulled its coveted "recommended" rating for the car, owing to that increasing evidence of that below-average reliability.
Another used electric car to avoid is the 2013 Nissan Leaf, staffers say.
