Hybrid-Electric Transit Buses: NYCT (New York City Transit) Diesel Hybrid-Electric Buses: Final Results (Brochure)
Final results of the New York City Transit Hybrid-Electric Transit Bus Study. Hybrid buses had lower emissions, higher fuel economy, and higher operating costs compared with diesel buses. New York City Transit (NYCT), part of the Metropolitan Transportation Authority in New York, began operating the first of 10 heavy-duty diesel hybrid-electric transit bus prototypes (Model VI) from Orion Bus Industries in 1998. All 10 buses were in revenue service by mid-2000. The hybrid buses are intended to provide NYCT with increased fuel economy and lower levels of harmful exhaust emissions, compared with NYCT's diesel transit buses. Between 1999 and 2001 (over various predefined fuel and maintenance evaluation periods), these first 10 hybrid buses were part of a data collection and analysis project sponsored by the U.S. Department of Energy (DOE). The operating costs, efficiency, emissions, and overall performance of these low-floor hybrid buses were compared against those of 14 conventional high-floor diesel transit buses (7 each from NovaBUS Corporation and Orion) operated by NYCT in similar service. Results indicate that the hybrid buses operate with greater fuel efficiency and much lower emissions, compared with the diesel buses. Maintenance costs for the prototype hybrid buses were significantly higher than those of the diesel buses during this evaluation. However, these costs are expected to decline for the next-generation Orion VII buses, currently being procured by NYCT, as repair technicians become more familiar with the advanced hybrid propulsion systems.
