Army goes green with hybrid vehicle

The Army is testing a "recently unveiled a 50 mpg hybrid utility vehicle that can replace the Humvee on many assignments," according to CNNMoney. The Army developed hybrid powertrain utilizes a removable 18-hp diesel engine, and two 10-hp electric engines and three batteries that supports interchangeable body types. Body types include passenger, pick-up, armored or one for remote control vehicles. Instead of the Humvee's 11 mpg, this hybrid achieves 50 mpg, and costs $20,000, instead of $65,000.
