Daimler Buses North America has received orders totaling 1,052 Orion VII Next Generation diesel-electric series hybrid transit buses. MTA New York City Transit has ordered 850 and the City of Ottawa (OC Transpo) has ordered 202. These buses will be powered by BAE Systems’ HybriDrive diesel-electric hybrid propulsion system and delivered into 2010.
This order will bring MTA’s diesel-electric hybrid bus fleet to almost 1,700 units, making it the largest diesel-electric hybrid fleet in the world. With this order, Orion transit buses will account for almost 50% of MTA New York City Transit’s entire fleet.
OC Transpo has ordered 202 Orion VII Next Generation diesel-electric hybrid transit buses to be delivered by 2009. This delivery will make OC Transpo the third largest hybrid bus fleet in Canada.
The hybrid drive in the Orion includes a 6-cylinder, in-line, 5.9-liter Cummins diesel that delivers 194 kW (260 hp) at 2300 rpm; a 120 kW generator; a 32 kWh battery pack (initially lead-acid, but a majority of the new orders will use a lithium-ion battery pack with cells from A123Systems (earlier post), according to Daimler); and a 186 kW (250 hp) traction motor that delivers 2,100 lb-ft (2,847 Nm) of torque (continuous), with 2,700 lb-ft (3,661 Nm) peak.
Compared to standard diesel propulsion, these hybrid buses deliver up to 30% better fuel economy while greatly reducing emissions: 90% less particulate matter, 40% less NOx and 30% fewer greenhouse gases.
With 1,100 hybrid transit buses already on the road, 460 pending deliveries and the announced new orders, Orion has received more than 2,600 orders for the hybrid since the launch of the Orion hybrid bus in 2003.
Daimler Buses North America, headquartered in Greensboro, N.C. (United States), is a Daimler AG company. It combines three commercial bus brands under one corporate structure: Orion transit buses, Setra motorcoaches, and the Dodge Sprinter shuttle bus.
