Allison Transmission has partnered with ElDorado National (ENC) to integrate the Allison H 40 EP electric hybrid propulsion system into the San Francisco Municipal Transportation Agency’s (SFMTA) Municipal Railway (Muni) buses.

This system reduces fuel consumption by up to 25% versus a conventional diesel bus, facilitates quieter operation, and reduces CO2 emissions.

“ENC is excited to partner with SFMTA and Muni on these buses which will utilize the Allison Hybrid EP system which dramatically reduces both diesel fuel consumption and CO2 emissions as compared to a conventional diesel transit bus,” said Mike Ammann, VP of Sales, ElDorado National (California).

SFMTA has awarded a contract to ElDorado for 30 electric hybrid E-Z Rider II model heavy-duty 30-foot transit buses. The contract features the Allison H 40 EP.

ElDorado said it expects to deliver the electric hybrid buses in the second quarter of 2022.

“We are proud to support SFMTA in its efforts to modernize its Muni fleet with ENC,” said Rohan Barua, VP of North America Sales, Global Channel and Aftermarket at Allison Transmission. “Allison’s electric hybrid solutions for transit buses are proven to demonstrate bottom-line operating benefits for municipalities and fleets all over the world while delivering industry-leading performance, reliability and durability, for nearly two decades and over several million miles of operation.”

Allison has delivered over 9,000 electric hybrid propulsion systems, serving 230 cities in 43 states. These systems have accumulated over 2.9 billion miles, saving more than 340 million gallons of fuel.
