No one's going to kill this electric car

The HEMTT A3, by truck maker Oshkosh, uses electric motors to drive all eight wheels, a diesel engine and generator to make electricity, and ultracapacitors for quick energy storage and release.

The Oshkosh hybrid HEMTT A3

This behemoth by truck maker Oshkosh uses electric motors to drive all eight wheels, a diesel engine and generator to make electricity, and ultracapacitors for quick energy storage and release. AutoblogGreen reports that several of these trucks, dubbed HEMTT A3, will be tested at the Aberdeen Proving Grounds by the Army. While the truck is technically a hybrid, Oshkosh calls the drive system ProPulse. But the use of electric motors to drive the wheels means the electricity could come from any adequate source. The system uses less fuel than a straight diesel drivetrain because the diesel engine can run at a constant speed, and it doesn't need a transmission or drive shafts. And with its electricity-generation capabilities, it can provide enough electricity when stationary to power a city block. The HEMTT A3 also uses regenerative braking.

The unmanned Oshkosh TerraMax

Oshkosh is developing the HEMTT A3 under a research contract from the military. We last saw Oshkosh's advanced technology research at the 2005 DARPA Grand Challenge, with the largest entrant in this unmanned vehicle desert race, the TerraMax. Oshkosh will be back for this year's DARPA Urban Challenge with a new, smaller version of the TerraMax.

Once the HEMTT A3s go into operation, will we see a civilian version, just the way the HMMWV spawned the Hummer?
