New US Humvee Burns 70% Less Fuel

24 Oct

The new vehicle, dubbed FED Alpha, will be on display this week in the Pentagon’s courtyard for an Energy and Sustainability Technology Fair. The vehicle has a solar panel on its back hatch to recharge its electrical systems, a custom engine and transmission along with several new features that will drastically increase its range and reliability over other models of Humvees. The new vehicle has all the toughness and survivability of the standard up-armored Humvee but burns 70% less fuel.

While the FED may not ever be mass-produced, it’s a valuable platform for testing the practical uses of environmentally friendly and sustainable technologies. The vehicle features a 200 horse-power 4 cylinder engine, a six speed automatic transmission and low-rolling resistance tires. The tires provide a 7% fuel reduction all by themselves. The savings from the tires alone are expected to save about $45 million annually if applied to the entire Humvee fleet. Their are several computer systems on board, such as one that informs the driver when they exceed the optimum fuel efficiency speed by causing the gas peddle to vibrate and giving resistance against more speed. However, if speed is essential to the mission, the driver just needs to push through the feedback.

Some other features of the FED are its high efficiency 28 volt integrated starter-generator that allows for extensive electronics to be installed, a light-weight aluminum structure except for the armored cab and v-shaped blast protection on the undercarriage. And finally, the FED has a much improved driveline specially designed to reduce friction.It’s been undergoing testing since July and another prototype design is under construction.
