Alexander Dennis Limited (ADL) has announced that its zero-emission capable Enviro400ER double decker has been fully certified as an Ultra-Low Emission Bus by the UK’s Low Carbon Vehicle Partnership (LCVP).
The ADL Enviro400ER is an electric range hybrid capable of running in zero-emission mode for up to three miles.
Developed in partnership with BAE Systems, it uses an electric driveline for smooth acceleration and braking. Powered by a 32kWh battery and charged by an on-board generator, the vehicle delivers zero emissions without any dependency on additional external charging infrastructure.
Alternatively, it can be charged externally through an industry standard plug-in connection.
The bus will save 31% “well-to-wheel greenhouse gas emissions” over the UK Bus Cycle compared to a Euro VI diesel bus of equivalent passenger capacity.
Ken Scott, Group Engineering Director at ADL, said: “The Enviro400ER’s certification as Ultra-Low Emission Bus confirms our position as the UK’s leading supplier of green buses. Capable of zero-emission operation, the Enviro400ER delivers immediate carbon savings and air quality benefits that can be further enhanced by the stepwise introduction of charging infrastructure.”
Ian Wilson, Business Development Director of Power and Propulsion Solutions at BAE Systems, explained that hybrid electric drive remains a key technology on the UK’s journey to achieve net zero emissions.
ADL launched the Enviro400ER in 2019 when Go-Ahead Group’s Brighton & Hove introduced 30 of the double-decker buses to cut out emissions in Brighton’s Ultra Low Emission Zone (ULEZ).
