INDIANAPOLIS, June 29, 2022 – Allison Transmission, a leading designer and manufacturer of conventional and electrified vehicle propulsion solutions for medium and heavy-duty commercial vehicles, announced that Emergency One, the UK’s largest manufacturer of fire and rescue vehicles, has integrated the Allison eGen Power® 100D electric axle into its new E1 EV0™ platform of fully electric fire and rescue vehicles.

“The industry-leading technology provided by the Allison eGen Power 100D was critical in bringing our latest E1 EV0 electric vehicle to market,” said Michael Madsen, Managing Director of Emergency One. “As the world’s first all-electric pumping vehicle that is fully certified to the BS EN1846 standard, EV0 exceeds standard requirements for electric driving range and pumping performance at zero emissions. This fire engine is the first in the UK to feature an innovative all-electric rear drive axle installation.”

The eGen Power 100D is a drop-in solution designed for easy installation into the current vehicle frame. The e-Axle integrates two high-speed electric motors and a multi-speed transmission, eliminating the need for additional drive shafts and support structures. One of the most powerful electric axle systems on the market, the eGen Power has a continuous output power of 454 kW and a peak output power of 652 kW. It was designed to deliver optimum efficiency, fast acceleration, high speed and increased maneuverability, which are all critical for fire and rescue vocations where failure is not an option and every second counts.

“We’re proud to continue our longstanding partnership with Emergency One to provide our award-winning e-Axle for their next-generation platform of electric vehicles,” said Heidi Schutte, Vice President of EMEA, APAC, and South America Sales, Allison Transmission. “The eGen Power 100D will offer our mutual customers, including many fire brigades and rescue teams across Europe, industry-leading performance and reliability while also supporting the industry’s sustainability efforts through innovative electric drive capabilities.”

The E1 EV0 fire engine, equipped with the Allison eGen Power 100D, was unveiled for the first time at Interschutz 2022, a fire and rescue industry tradeshow in Hanover, Germany, from June 20-25, 2022. The all-electric pumping engine has been sold to the Scottish Fire and Rescue Service and is expected to be put into service in early 2023. The vehicle will assist crews in responding to fire and rescue emergencies.
