Design

Alexander Dennis announced the launch of a battery electric variant of its Enviro500 MMC tri-axle double decker in 2021 for the North American market, initially marketed as the Enviro500EV CHARGE. The North American Enviro500EV, seating 130 passengers and sharing components with the 2-axle Enviro400FCEV developed for the UK market, is equipped with a 648  kWh battery. [4] [5] A revised Enviro500EV for the North American market, featuring an integrally-constructed powertrain, battery capacities of 709kWh or 827kWh, a higher operating range of up to 340 miles (550 km) and a new exterior design in line with both the UK market's Enviro400EV and Enviro100EV buses, was launched in June 2025. [3]

For the Asian and Oceanian markets, Alexander Dennis launched the Enviro500EV in August 2022 with an all-new body style and an integrally-constructed powertrain as part of a major redesign of its electric bus range, initially marketed towards bus operators in Hong Kong as the Enviro500EV NG. [6] In either New Zealand or Hong Kong specification, the Asian and Ocenaian Enviro500EV is capable of seating between 100 and 117 passengers, with between 82 or 88 seated and the remainder standing or in dual wheelchair spaces. Both variants are powered by 472kWh NMC batteries, with the range of the bus subject to operating conditions, and feature dual doors and air conditioning as standard. [1] [2]
