The U.S. Army unveiled its first hybrid-electric propulsion system for a new fleet of Manned Ground Vehicles (MGVs). The Army is developing and building eight new MGV variants for 15 Future Combat Systems Brigade Combat Teams (FCS BCTs). All eight commonly-designed MGV variants will provide Soldiers with enhanced survivability, increased speed and mobility, new network-based capabilities, and more modern, modular technology. All the eight variants will have a common chassis saving the army a great deal of money. For the first time the Army will be integrating a functional hybrid-electric drive system into a combat vehicle. The drive system is part of the propulsion system that will power the vehicles.
