INDIANAPOLIS, March 4, 2013 /PRNewswire/ --Allison Transmission Holdings,
Inc. (NYSE: ALSN) today announced that it will unveil its H 3000

heavy-duty trucks in distribution, refuse, utility and shuttle applications.

"We're thrilled to bring Allison's world-renowned reliability, durability and
technical expertise to a new hybrid product for our commercial truck and bus
customers," said Laurie Tuttle, Vice President of Hybrid Programs for Allison

The fully-automatic parallel hybrid-propulsion system is based on the Allison
3000 Series transmission which is matched with hybrid system components,
including a motor-generator, power electronics and lithium-ion cell battery
packs. Scalable to each application, the modular lithium-ion battery packs
enable an optimal amount of energy capacity to be tailored to a specific
vehicle or duty cycle, allowing for greater flexibility and performance.

"We began pioneering hybrid technology in 1989 and, since 2003, have delivered
more than 5,000 hybrid-propulsion systems for the transit bus market," said
Tuttle. "With the launch of the new H 3000, we'll now provide this technology
for a much wider range of vehicles."

The H 3000 captures otherwise wasted energy during vehicle braking and uses it
to assist in vehicle propulsion and powering of auxiliary equipment. The
design features a torque converter fully-automatic transmission and the hybrid
motor-generator which enables fleets to maximize efficiency while achieving
outstanding performance and productivity.

Since the system is built with Allison's fully-automatic 3000 Series, it
provides smooth, uninterrupted power to the wheels. The H 3000 will also come
equipped with Allison's latest generation of electronic controls which offer a
variety of features to further improve productivity and efficiency. Depending
on vocation and duty cycle, the system is designed to offer fuel savings of up
to 25 percent. Production is expected to begin later this year.

Attendees of The Work Truck Show can experience the H 3000 during the Green
Truck Ride-and-Drive events on Wednesday and Thursday.
