Oshkosh to Show HEMTT A3 Hybrid Truck in Atlanta

Font size: Decrease font Enlarge font

Oshkosh Corporation will display its Heavy Expanded Mobility Tactical Truck (HEMTT) A3 equipped with ProPulse diesel electric hybrid system at CALSTART’s Hybrid Truck Users Forum in Atlanta.

Attendees will be offered rides in the Oshkosh vehicle on Oct. 29 at Turner Field. The Oshkosh ProPulse vehicle provides a substantial fuel economy improvement for the application of a hybrid drivetrain in a military vehicle.

The HEMTT A3 is equipped with the Oshkosh proprietary ProPulse diesel electric hybrid system, a technology currently under various stages of development across several commercial and military Oshkosh vehicle platforms.

Earlier this month, the Oshkosh HEMTT A3 outperformed a similar but conventional drive vehicle in multiple scenarios, including a range of steady speeds and aggressive acceleration starts and stops. The HEMTT A3 demonstrated a 24 percent improvement in fuel economy at 60 mph cruising speed and a 33 percent improvement in a start-and-stop-cycle.
The HEMTT A3 is equipped with a load handling system which can off-load a C-130 aircraft, has a variable height independent suspension and lower center of gravity for increased maneuverability and handling. The HEMTT A3 can export up to 100 kW of clean, military-grade electrical power making the A3 ideally suited to support initial deployment of troops, bring electrical power to remote areas, as well as support recovery missions in the event of a natural disaster.

The Oshkosh ProPulse technology can be integrated into any new vehicle design, like the HEMTT A3. Additionally upgrade kits are available for existing vehicles, such as the Oshkosh Medium Tactical Vehicle Replacement (MTVR) with OBVP to provide on-board vehicle power (OBVP). The technology also has been integrated on an
Oshkosh commercial chassis in a refuse hauling application as part of the Advanced Heavy Hybrid Propulsion System Project sponsored by the Department of Energy and the National Renewable Energy Laboratory.
