INDIANAPOLIS, Feb. 8, 2017 /PRNewswire/ -- Allison Transmission Holdings Inc. (NYSE: ALSN) and Cummins Inc. (NYSE: CMI) today announced certification from the California Air Resources Board (ARB) for model year 2017 Allison Hybrid H 40 EP™ / H 50 EP™ propulsion systems paired with the Cummins B6.7 and L9 diesel-electric hybrid engines used in transit buses and coaches.

Originally issued by the ARB in 2014, the dual Executive Order (EO) is required to be reviewed for renewed eligibility on a model year basis. The paired Allison Hybrid EP systems and Cummins engine is used in both straight and articulated transit buses.

"We appreciate ARB's continued renewal," said Greg Mann, director of mobile source emissions activities for Allison Transmission.

The Allison H 40/50 EP has been proven to improve fuel economy up to 25 percent over similar diesel buses. Additionally, its regenerative braking capability can significantly extend the brake change interval by as much as 350 percent.

"Cummins is pleased the Allison hybrid system has received 2017 certification from the ARB as it will provide transit customers with system continuity using our proven diesel-electric engine configurations designed to meet business and environmental needs. For 2017, our latest generation of B6.7 and L9 engines are enhanced with improved fuel economy, and higher uptime, resulting in better operating costs," said Laura Chasse, general manager of North American Bus Business. 

The Cummins B6.7 and L9 diesel-electric hybrid engines feature proven technology designed and developed in-house that is optimized to deliver the efficiency, durability and performance on which transit bus customers depend. The B6.7 diesel-electric hybrid engine is rated at 280 hp (209kW) while the L9 diesel-electric hybrid engine is rated at 330 hp (246kW) for the transit bus market.
