INDIANAPOLIS, Ind. — Allison Transmission has introduced a fully automatic hybrid system for medium- and heavy-duty distribution, refuse and utility vehicles.

The company unveiled the H 3000 system at the Work Truck Show.

“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 Transmission.

The system is based on Allison’s 3000 Series transmission, which is matched with a motor-generator, power electronics and lithium-ion cell battery packs.

The system captures energy during braking and uses it to help propel the vehicle and power auxiliary equipment. Allison says the use of its 3000 Series transmission ensures smooth, uninterrupted power is supplied to the wheels.

“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.”

Depending on application, Allison says fuel savings could total up to 25%. The system is expected to go into production later this year.
