Allison Transmission and Eldorado National partner for electric hybrid buses


Allison Transmission (Indianapolis, Indiana) announced the 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, 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, which will feature the Allison H 40 EP. This system reduces fuel consumption by up to 25% 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, for nearly two decades and over several million miles of operation.”

Allison has delivered more than 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, and preventing 3.4 million metric tons of carbon dioxide from entering the atmosphere.
