Oshkosh Corporation Displays Fuel Efficient Military Vehicle at Hybrid Truck Users Forum

OSHKOSH, Wis.--(Business Wire)--
Oshkosh Corporation (NYSE:OSK) announced today its Heavy Expanded Mobility
Tactical Truck (HEMTT) A3 equipped with ProPulse® diesel electric hybrid system
is on display October 27 - 29 at CALSTART`s Hybrid Truck Users Forum (HTUF) 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.

"We focused our efforts on optimizing the vehicle design and engine control
strategy to maximize fuel economy, and those efforts have paid off
significantly," said Gary Schmiedel, Oshkosh Corporation vice president of
Advanced Product Engineering. "We`re sharing the research results for the first
time this week because the Hybrid Truck Users Forum brings together the best in
industry technology with the U.S. Army. At Oshkosh Corporation, we take a
similar approach towards excellence by applying leading technologies with a
strong customer focus in an effort to better serve our military customers."

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.

In addition to the benefits of increased fuel economy, the Oshkosh HEMTT A3
provides a better crew environment because noise and vibration are reduced.
Also, the simplified drivetrain and the resultant flexibility of equipment
positioning, allow for increased vehicle capabilities and reduced maintenance
requirements. 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.

"We are proud of the initiative and investments member companies like Oshkosh
are making to develop new, efficient and clean technologies for heavy-duty and
military trucks," said Bill Van Amburg, senior vice president CALSTART.
"Together we will help improve our national security by lessening our dependence
on fossil fuels."

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.
