Daimler Buses North America has announced that it received orders totaling 1,052 for Orion VII Next Generation diesel-electric hybrid transit buses, 850 for the MTA New York City Transit, and 202 for the City of Ottawa’s OC Transpo, for delivery into 2010.
This order will bring the MTA's diesel-electric hybrid bus fleet to almost 1,700 units, making it the largest diesel-electric hybrid fleet in the world, accounting for almost 50 percent of MTA's entire fleet.
With already 1,100 diesel-electric hybrid transit buses on the road, 460 pending deliveries and these new orders, Orion has received over 2,600 orders since the launch of the Orion hybrid bus in 2003.
The Orion VII transit buses are powered by BAE Systems' HybriDrive(R) propulsion system. The series power train consists of the following:
- A 6-cylinder, 6-liter, 194 kW (260 hp) Cummins diesel, running at nearly constant speed.
- A 120 kW generator producing electric power for the batteries.
- A single 186 kW (250 hp) electric motor drives the vehicle and regenerates energy during braking.
- A 32 kWh A123 lithium-ion battery pack, in the majority of buses, supply power during acceleration and hill climbing as well as storing energy from regenerative braking.
Compared to standard diesel propulsion, these hybrid buses deliver up to 30 percent better fuel economy while greatly reducing emissions: 90 percent less particulate matter, 40 percent less NOx and 30 percent fewer greenhouse gases. Drivers and riders enjoy a quieter, cleaner and smoother ride.
Production of all Orion V, and VII buses begins at the Mississauga, Ont. Canada factory where the integrated chassis/body structure for each bus is assembled. The structure is then shipped to the Oriskany, NY plant where seating, engines, transmissions, axles, electrical, heating and air conditioning systems, and other final finish components are installed.
