The Wheels On The Bus Are Green, Green, Green
We’ve recently learned from Warrenville’s Navistar
International (parent company of IC Corporation, the nation’s
largest school bus manufacturer) what’s new and exciting in
the world of school bus technology. IC has teamed up with a
leading power systems supplier, Enova Systems, to introduce
the first hybrid school buses in the nation. The bus, which
was extensively, and successfully, tested and evaluated last
spring, couples a V8 diesel engine with an 80 kilowatt
hybrid-electric powertrain, incorporating a transmission,
batteries, and an electronic motor. According to IC Corp, this
power system “recovers kinetic energy during regenerative
braking, charging the batteries while the bus is slowing
down-making school buses ideal candidates for hybrid
technology because of the frequent stops and starts they
perform along their daily routes.”
Hybrid school buses are expected to attain a 40% increase
in fuel efficiency, and to reduce engine emissions as well.
Eleven states (AZ, CA, FL, IA, NC, NE, NY, SC, TX, VA, and WA)
will be the first to receive the new school buses. To learn
