U.S. Army hybrid vehicle saves fuel and lives

Quantum CERV buggy can creep up on enemy in silence

Green is a word most often used to describe the army’s uniform, not its transport. However, images of gas-guzzling army vehicles could soon be history, as the US Army has started developing hybrid vehicles.

At this week’s Chicago Auto Show, the US Army presented its latest innovation called the Clandestine Extended Range Vehicle or CERV. This light armoured buggy is intended for reconnaissance missions, and thanks to a silent electric vehicle mode it can travel for up to eight miles on rough terrain without being heard by the enemy.

The CERV is a joint development project between Quantum Fuel Systems Worldwide, a company that specialises in renewable energy propulsion, and the US Army’s Tank Automotive Research, Development and Engineering Centre. It can use up to 25% less fuel than equivalent diesel models, which could slash the military’s bills.

The hybrid can hit speeds of up to 80mph and climb slopes as steep as 60 degrees, and can also ford up to 30 inches of water. Its diesel hybrid-electric powertrain produces in excess of 5,000 lb-ft of maximum torque, which is available immediately. CERV uses a 1.4-litre diesel engine connected to a 75kW generator. This is combined with power from lithium ion batteries that feed a 100kW permanent magnet drive motor.

All this is bolted to a special lightweight chassis, which enables the scouting vehicle to be transported by a number of military aircraft, such as the Osprey rotorcraft.

On top of the advantages that a stealth ground-vehicle offers, by cutting down on diesel consumption the CERVs can also help reduce the risks involved with transporting and guarding fuel supplies. Fuel transports are obvious targets for enemy combatants and are reportedly one of the most dangerous jobs a soldier can do.
