Consumers aren’t the only ones concerned with saving money on gas. The U.S. Army unveiled its Fuel Efficient Demonstrator (FED) Bravo concept at the Society of Automotive Engineers (SAE) World Congress sporting a diesel-hybrid setup in hopes of reducing the cost and risk with delivering fuel to its military vehicles.
Under the hood of the FED Bravo is a Ford-sourced 4.4-liter, twin-turbocharged V8 diesel powerplant with 268-hp. Weighing in at 16,760 lbs, the FED Bravo features a six-speed automatic transmission and hybrid drive for the rear axle in addition to an electric motor to power the front wheels.
The motors are powered by a lithium-ion battery pack that can also uses regenerative braking. And like all other hybrids on the market, it features start-stop technology to save fuel and can travel up to 5 miles on electric power alone. In hopes to shave some weight off the FED Bravo, the team utilized carbon-ceramic brake rotors rather than steel brake disks.
Compared to the traditional Humvee, the FED Bravo gets 8.2 mpg in the city and 14.2 mpg on the highway. While that may not sound impressive compared to a conventional hybrid, the current Hummer gets an underwhelming 3 to 6 mpg.
The FED Bravo is treated strictly as a concept right now, but there’s no doubt some of the technology that has been put into it will surface in future military vehicles.
