The new product is targeted for medium- and heavy-duty trucks in distribution, refuse, utility and shuttle applications.

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, says Laurie Tuttle, vice president of hybrid programs at Allison Transmission. 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,” says Tuttle. “With the launch of the new H 3000, we’ll now provide this technology for a much wider range of vehicles.”

Allison says 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 the company says enables fleets to maximize efficiency while achieving outstanding performance and productivity.

The H 3000 also will 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, Tuttle says the system is designed to offer fuel savings of up to 25 percent.

Production is expected to begin later this year.
