Indianapolis-based Allison Transmission Holdings Inc. (NYSE: ALSN) has signed an agreement with IndyGo to provide its next generation electric hybrid propulsion system for more than two dozen IndyGo buses. Allison Chief Executive Officer David Graziosi says the new partnership is the continuation of a longstanding collaboration focused on innovation.
As part of the deal, Allison says it will pair its H 40 EP electric hybrid transmission with the B6.7 engine from Columbus-based Cummins Inc. (NYSE: CMI) in 24 of the 27 buses procured by IndyGo.
“This propulsion solution will enable these buses to save up to 25% in fuel consumption versus conventionally-fueled buses,” said Graziosi. “This unique, electric hybrid solution has saved more than 305 million gallons of diesel fuel and eliminated more than 3 million metric tons of CO2 emissions through more than 9,000 systems that have been fielded since 2003.”
The remaining three buses will receive Allison’s new eGen Flex electric hybrid system, which was unveiled earlier this week. Allison says the system will allow the buses to enable pure electric operation for up to 10 miles on any route without capital infrastructure investment in charging stations.
The manufacturer says the system is capable of improving fuel economy by up to 25% compared to a conventional diesel bus, while also reducing emissions and noise. It will also allow the buses to operate their heating and air conditioning systems on electric power, which will reduce engine strain, according to Allison.
“By integrating eGen Flex-equipped buses into their fleet, IndyGo has demonstrated to our community that they are committed to reducing dependence on fossil fuels, enhancing the quality of life in our community, protecting the environment, and minimizing their total cost of ownership,” Rohan Barua, vice president of North America sales for Allison, said in a news release. “We are very pleased to continue our long-term partnership with IndyGo and look forward to the innovation this collaboration will deliver to our community.”
IndyGo CEO Inez Evans says the partnership lays the foundation for future collaboration on clean air propulsion.
