Indianapolis-based Allison Transmission (NYSE: ALSN) is partnering with Columbus-based Cummins Inc. (NYSE: CMI) and GILLIG in California to deliver 24 electric hybrid buses to IndyGo. Allison says the system improves fuel consumption by up to 25% versus a conventional diesel bus and reduces CO2 emissions, helping to protect the environment.
Allison’s H 40 EPTM electric hybrid propulsion system is paired with the Cummins B6.7 engine in GILLIG buses.
“Given the constant evolution, high capital expenses associated with charging infrastructure and other quality and reliability concerns, many transit properties across the country are struggling to implement fully electric solutions for their fleets,” said Rohan Barua, vice president of North America sales, global channel and aftermarket at Allison Transmission. “The Allison eGen Flex is a viable, reliable option that allows fleets to protect the environment and improve ridership experience right now.”
Additionally, Allison says its electric hybrid system will be integrated into three of IndyGo’s new buses beginning in 2022, providing full electric operation for up to 10 miles. The system will enable IndyGo buses to eliminate engine emissions and noise by operating the bus with the engine off when the bus is stopped at bus stops and in pedestrian areas.
“This product [eGen Flex] helps IndyGo achieve its goal to become a clean fleet or near-zero emission fleet,” said Inez Evans, IndyGo president. “As we move toward that goal, eGen Flex gives us a solution that will still provide the mileage range that a diesel bus would offer so we can also meet all of our service needs. This will help reduce our carbon footprint and meet that near-zero emission footprint we are striving for.”
Allison says the propulsion system provides fleets with full electric capability when required, as well as the ability to operate in hybrid mode when needed for longer routes, and it does not require an external charging source for its operation.
