A heavy-duty parallel hybrid vehicle is the centre of attraction at the Military Utility Assessment (MUA) tests at Fort Lewis, Washington. The powerhouse vehicle- Future Tactical Truck System Maneuver Sustainment Vehicle or FTTS-MSV- is developed for the U.S. Army and has already been tested for nearly 3,000 miles before being subjected to the current Military Utility Assessment (MUA) tests. FTTS-MSV comprises of an 8.8-liter Caterpillar C9 diesel engine, a 120 kW UQM hybrid electric motor, and a 336V 3 kWh Cobasys NiMH battery pack with a 7-speed automatic transmission. The winning point of this multi-wheel giant is its highly fuel-efficient engine which can work wonders in increasing supply ranges to between 600 and 900 miles, which is almost double to triple than what the current tactical vehicles employed with the U.S. Army are giving. The highly fuel-efficient FTTS-MSV will be a boon to the U.S. Army, as supply ranges play one of the most important roles in any land combat. Source.
