Allison Transmission Receives California Air Resources Board Certification for Hybrid-Electric Propulsion System with Cummins Engines

INDIANAPOLIS — Allison Transmission Holdings, Inc. (NYSE: ALSN) and Cummins, Inc. (NYSE: CMI) announced on May 31 the certification from the California Air Resources Board (ARB) for model year 2019 Allison Hybrid 40/50 Electric Propulsion (H 40/50 EP) system, paired with the Cummins B6.7 and L9 diesel-electric hybrid engines that are used in transit buses and coaches. The B6.7 is the leading diesel engine that is used in large school buses.

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 electric hybrid-propulsion system and Cummins engine are used in both straight and articulated transit buses.

“We appreciate ARB’s continued renewal,” said Barbara Chance, director of mobile source regulatory compliance for Allison Transmission. “Allison was the first electric hybrid-propulsion system to be certified in California for transit buses and coaches. We look forward to continuing our work with ARB.”

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 electric hybrid-propulsion system has received 2019 CARB certification,” said Brian Wilson, GM of the global bus business at Cummins, Inc. “We believe the latest Cummins and Allison clean diesel power system will provide our bus customers an even more reliable and environmentally-friendly powertrain to help them be as successful as possible. For 2019, our latest generation of B6.7 and L9 engines are enhanced with improved fuel economy, and improved uptime, reducing overall costs for customers.”

The Cummins B6.7 and L9 diesel-electric hybrid engines feature proven technology that is designed and developed in-house and 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.
