Thomas Saf-T-Liner C2e Hybrid School Bus Prototype '07.2008

The first prototype was built in 2008 and underwent evaluation. It was displayed at the 2008 School Transportation News School Bus EXPO in Reno, Nevada and the National Association for Pupil Transportation Conference and Trade Show in Myrtle Beach, South Carolina. The 2008 prototype used a Mercedes-Benz diesel engine and an Eaton parallel hybrid system.

High Point, N.C. – A prototype of a hybrid Saf T Liner® C2 school bus is currently being evaluated in North Carolina. The vehicle should reduce emissions and improve fuel economy by 30 percent or more. The prototype bus, powered by a Mercedes Benz diesel engine, an Eaton transmission, and an electric motor, was developed jointly by Thomas Built, Eaton Corporation and Freightliner Custom Chassis Corporation.

The powertrain used in the hybrid bus has been refined for more than two years in a delivery van application developed by Freightliner Custom Chassis and Eaton. Approximately 200 vehicles have been built and are currently in operation. The experience gained from the hybrid delivery vans (which have an operating profile similar to a school bus) is being leveraged by Thomas for the school bus market. In those vans, tests revealed a fuel savings of 300 to 450 gallons per year, based on annual mileage of 10,000 miles. Assuming a $3 per gallon fuel price, the annual cost savings is between $900 and $1,350 per year.

Other advantages of Thomas’ hybrid bus are expected to include reduced brake wear and component maintenance and quieter operation. There’s even an advantage that can’t be measured in dollars: the boost to a school district’s image from driving a fleet of environmentally responsible school buses.

The Thomas Built hybrid prototype bus will be shown at 2008 pupil transportation events including the School Transportation News School Bus EXPO in Reno, Nev., July 28-20 and the National Association for Pupil Transportation Conference and Trade Show in Myrtle Beach, S.C., October 26–30.
