U.S. Army considering hybrid trucks

Truck, a Wisconsin based provider of the Army’s heavy cargo-hauling HEMTT (Heavy Expandable Mobility Technical
Truck), is developing an electric hybrid variant for the U.S. Army, and has just signed a contract do develop a
prototype of a similar vehicle for the Marines. In addition to increasing fuel economy from 3 to 4 miles per gallon,
the hybrid powertrain could generate enough electricity to power a city block or a hospital, a valuable capability when
operating in underdeveloped or disaster areas. While the increase in fuel economy might be modest, approximately 70% of
what military vehicles carry is fuel. The adaptation of hybrid technology to heavy vehicles is not a straightforward
process. Military vehicles often have to operate off-road, carry large amounts of cargo, and endure severe grades,
which have an impact on the design of the vehicle. This newest version of the HEMTT uses a diesel engine which powers a
generator that sends power to electric drive axles, while energy is stored through regenerative braking. The approach
allows reduction in vehicle weight and easier maintenance, on top of the fuel savings. [Source: Houston Chronicle]

I drive a hybrid and wish everyone did. I think that anything the Army does in the way of hybrid trucks will make people stop and consider one themselves. I live in a city that has a high military population and this technology would really make a difference. I think that they need to seriously consider replacing the mps cars with hybrid vehicles. That would make a big difference immediatly.
