Alexander Dennis Enviro500EV

The Alexander Dennis Enviro500EV is a low-floor, three-axle battery electric double-decker bus built by the British maker Alexander Dennis for the Asia and Oceania and North American markets. It began in 2021 as a battery electric variant of the Enviro500 MMC for North America, first marketed as the Enviro500EV Charge. In August 2022 the company launched a redesigned version with an integral powertrain for Asia and Oceania, marketed to Hong Kong operators as the Enviro500EV NG, which carries between 100 and 117 passengers on 472 kWh batteries. The first production bus went to Kowloon Motor Bus of Hong Kong in April 2023, and MTR Bus began taking delivery of 35 from late 2024. A revised North American version with 709 or 827 kWh batteries and a range of up to 340 miles was launched in June 2025, and Sound Transit of Seattle ordered 33 of them for its Stride bus rapid transit scheme in February 2024.
