The Alexander Dennis Enviro200EV is a battery electric single-deck bus produced by the British bus manufacturer Alexander Dennis in partnership with Chinese electric vehicle manufacturer BYD Auto since 2015.

Design

An electric variant of the diesel integral Alexander Dennis Enviro200 MMC, which had been launched that same year to replace the outgoing Enviro200 and Enviro300, the first-generation Enviro200EV launched in 2015 utilises BYD's own 12 m (39 ft 4 in) chassis and drivetrain and has a range of up to 160 miles with a recharge time of 3.5 hours. A shorter 10.8 m (35 ft 5 in) variant was subsequently added to the range in 2016.

The lithium iron phosphate batteries of the first-generation Enviro200EV are stored on the roof of the bus. From the beginning of production, the battery store was arranged in a 'pod' layout, which was replaced in 2020 by a revised and more aerodynamic arrangement that removed the need for the 'pod'.

A second-generation Enviro200EV, using "in-house" battery-electric technology and featuring a restyled exterior, driver's cab and passenger compartment similar to the Enviro100EV, was revealed by Alexander Dennis in October 2024 ahead of the 2024 Euro Bus Expo. The second-generation Enviro200EV will be available at lengths of 9.9 metres (32 ft), 10.9 metres (36 ft) and 11.7 metres (38 ft) for regional operators, providing a maximum capacity of 92 passengers with up to 43 seated, with Transport for London (TfL) specification Enviro200EVs additionally being offered in 10.4 metres (34 ft) length. Unlike the Enviro100EV and second-generation Enviro400EV, which use NMC batteries, the second-generation Enviro200EV will retain the use of lithium iron phosphate batteries.

Operators

First generation (2018-2025)

United Kingdom

Go-Ahead London were the launch customer for the Enviro200EV, ordering 51 of the type in July 2015 after trialling two integral BYD K9 electric buses for use on routes 507 and 521. Further deliveries included 14 examples for route 360, 30 more in 2018 for use on routes 153 and 214, and 130 of the type being supplied for various routes across London throughout 2023.

Other TfL contractors who operate first-generation Enviro200EVs include London United, who operate 100 of the type which were delivered across two batches in 2018 and 2021, Metroline, who purchased 23 Enviro200EVs for use on route 46, and Stagecoach London, who purchased five of the first Enviro200EVs to feature the redesigned roof layout for service on route 323.

Outside London, the first 12 Enviro200EVs to enter service outside of the capital were delivered to Arriva Merseyside in 2017. Three Enviro200EVs were also delivered to Salisbury Reds in 2020 for park and ride services in Salisbury. Since then, the Stagecoach Group has become a popular operator of Enviro200EVs, most commonly in Scotland; the group's first nine Enviro200EVs were delivered to Stagecoach South for use in Guildford on 'Glide' park and ride services in January 2019. Further orders for the group's Scottish operations, funded in part by the Scottish Zero Emission Bus (ScotZEB) challenge fund, began to be delivered in the early 2020s; Stagecoach East Scotland first took delivery of nine Enviro200EVs for service in Perth, followed by further 13 to electrify the city's bus network in early 2023 and eleven Enviro200EVs for service Dunfermline in 2023. Stagecoach West Scotland, meanwhile, took delivery of 15 Enviro200EVs for service in Kilmarnock in 2021, joined by a further two in early 2023.

First Glasgow first took delivery of two Enviro200EVs for trial service in January 2020, which was followed by an order for 22 more of the type in March 2021; prior to entering public service in November, these were used as shuttle buses for the 2021 United Nations Climate Change Conference being held in the city. This was followed by a repeat order for 50 more Enviro200EVs, which began to be delivered to the company's Scotstoun depot in June 2023. Elsewhere in Glasgow, three dual-door Enviro200EVs were delivered by National Car Parks in 2019 for car park shuttle services at Glasgow Airport.

A handful of Enviro200EVs are also in use by operators on private or local authority contract bus services. Ten delivered between 2022 and 2024 are operated by Cobra Corporate Services on private shuttle services for Sky UK campuses in Osterley and Livingston, while four Enviro200EVs, two being 10.8 metres (35 ft) examples and another two being 10.2 metres (33 ft) examples, were delivered to Stagecoach in Mansfield for use on Nottinghamshire County Council contracted 'Nottsbus' services between 2018 and 2021, and the South Yorkshire Mayoral Combined Authority took delivery of four Enviro200EVs in March 2024, entering service on 'Sheffield Connect' shuttle services on 8 April.

Exports

The National Transport Authority of Ireland have ordered 200 Enviro200EVs to be delivered to operators across Ireland over a period of five years, specified at 12 metres (39 ft) length with dual doors and spaces for wheelchairs and prams as well as a raked front windscreen. Deliveries commenced in January 2023, with the first 11 Enviro200EVs entering service with Bus Éireann in Athlone.

In New Zealand, eight Enviro200EVs were delivered to Auckland Transport operator Fullers360 in late 2020 for services connecting the Auckland Region's Waiheke Island. An electric demonstrator based on the tri-axle Enviro200 XLB was later delivered in August 2021 to Auckland Transport.

Second generation (2025-)

The first major pre-production order for the second-generation Enviro200EV was placed by the Stagecoach Group in June 2024, with 54 Enviro200EVs intended for Stagecoach subsidiaries receiving central government funding from the Zero-Emission Regional Bus Areas (ZEBRA2) scheme due for delivery between 2025 and 2026.

The first independent bus operator to order the second-generation Enviro200EV was Falcon Buses of Byfleet, who plans to take delivery of 13 10.9 metres (36 ft) examples of the type in 2026.
