Allison Transmission, ElDorado National partner to bring electric hybrid buses to San Francisco

Aug. 30, 2021
ElDorado expects to deliver the electric hybrid buses in the second quarter of 2022.

Allison Transmission’s Allison H 40 EPTM electric hybrid propulsion system will be integrated into the San Francisco Municipal Transportation Agency’s (SFMTA) Municipal Railway (Muni) buses, in partnership with ElDorado National (ENC). 

“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, vice president of sales, ENC (California). 

SFMTA awarded a contract to ElDorado for 30 electric hybrid E-Z Rider II model heavy-duty 30-foot transit buses, which will feature the Allison H 40 EP. This system reduces fuel consumption by up to 25 percent versus a conventional diesel bus, facilitates quieter operation and reduces CO2 emissions, helping to protect the environment.  

In addition, the H 40 EP Series is equipped with regenerative braking, a system that converts the vehicle’s kinetic energy to stored electric energy when decelerating or stopping. ElDorado 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, vice president 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.”
