Hybrid Electric-High Mobility Multipurpose Wheeled Vehicle (HE-HMMWV)

The U.S. Army asked CTC to produce a reasonably affordable and efficient hybrid electric vehicle using currently available technology.  The vehicle had to meet or exceed the baseline performance of the conventional/current High Mobility Multipurpose Wheeled Vehicle (HMMWV).

CTC-developed hybrid-electric powered HMMWV exceeds performance expectations.

CTC successfully converted the conventionally powered HMMWV to a hybrid-electric (HE) powered vehicle for the U.S. Army.  The vehicle exceeds the conventional HMMWV in gradeability, fuel efficiency, acceleration and top speed.  In addition, the new vehicle offers stealth operation and has the potential for a remote power source.  Specifically:

• CTC’s HE-HMMWV achieved 17.9 miles per hour (mph) on a 40% grade as compared to 9.4 mph for the current U.S. Army M1097 HMMWV.

• CTC’s HE-HMMWV achieved 20.9 miles per gallon (mpg) at a speed of 60 mph as compared to 7.1 mpg for the current M1097 moving at 60 mph.

• CTC’s HE-HMMWV accelerated from 1 to 60 mph in 17.3 seconds as compared to 54.8 seconds for current U.S. Army M1097 conventionally-powered vehicles.

• CTC’s HE-HMMWV exceeded the project’s maximum speed goal of 70 mph on level, paved roads, attaining 72.3 mph.
