The Allison Hybrid H 40 EP is a two-mode parallel hybrid that operates automatically as a parallel hybrid or series hybrid, to offer an infinite number of ratios, which can be automatically adjusted to operate at optimum power curves to enhance performance and fuel economy.
Allison’s Hybrid System has been deployed in approximately 3,500 buses and coaches that are operating in over 160 cities worldwide, including the transit agencies of Chicago, Philadelphia, Washington DC, Seattle, Houston, Minneapolis-St. Paul, Baltimore, Vancouver and Yosemite National Park.
The deployment of these buses is estimated to save approximately 13.5 million gallons of fuel, while eliminating over 130,000 metric tons of CO2. The Orion transit buses featuring Allison Hybrid H 40 EP are expected to be available in 2011.
Daimler Buses North America chief commercial officer Patrick Scully said that the Allison Hybrid System further enhances Orion’s current hybrid leadership and now allows customers to specify which hybrid system is best suited for their specific needs.
