IC Corporation and Enova Introduce First Hybrid School Bus; Plug-In Configuration as an Option (updated)

IC Corporation, North America’s largest school bus manufacturer, unveiled the nation’s first hybrid school bus today at the New York Association of Pupil Transportation (NYAPT) Show.
The company, a subsidiary of Navistar International Corporation, has partnered with Enova Systems to develop the hybrid, which can deliver about a 40% increase in fuel economy. (Earlier post.)

The initial powertrain for the hybrid school bus will couple an International VT365 V8 diesel engine with a post-transmission 80 kW Hybrid Drive System, incorporating a transmission, batteries and an electric motor. The system is based on a parallel architecture.
The company will offer two battery systems—NiMH and PbA—as well as a plug-in configuration that uses an NiMH battery pack. (More information to come.)
The system recovers kinetic energy during regenerative braking, charging the batteries while the bus is slowing down. This provides additional power for acceleration, making the hybrid buses ideal because of the frequent starting and stopping of the bus.
With fuel prices near all-time highs, new innovations in hybrid technology are needed to help customers keep their operating costs lower. We feel that this technology provides significantly improved fuel economy. In addition, even though current International diesel engines produce no visible smoke and minimal emissions, the hybrid program will reduce engine emissions even further.—Michael Cancelliere, vice president and general manager of IC Corporation
We believe our non-invasive Post Transmission Design, and partnership with IC Corporation, provides opportunities for both future production and the aftermarket retrofit sectors.—Mike Staran, vice president of marketing for Enova
The first hybrid school bus will be delivered by Leonard Bus Sales in Deposit, N.Y., to Shenendehowa Central School, one of the largest school districts in the state. The deal is pending final approval on a grant to help fund the purchase.
