Alexander Dennis Enviro100EV

The Alexander Dennis Enviro100EV is a battery electric integral midibus built by British bus manufacturer Alexander Dennis. It is the first midibus produced by the company equipped with Alexander Dennis' own in-house electric drivetrain, complementing the BYD-powered Enviro200EV in the Alexander Dennis product range. The body of the bus is to be assembled in Zhuhai in China, while the chassis of the bus is to be assembled with the body at the Alexander Dennis factory in Scarborough in England.

The Enviro100EV was announced as a new model in the Alexander Dennis range on 1 November 2022 at the Euro Bus Expo at the National Exhibition Centre in Birmingham, England, with the first production model unveiled a year later on 1 November 2023. The bus is primarily marketed at smaller bus operators running bus services in rural areas, although plans have been made to potentially introduce a Transport for London specification Enviro100EV by mid-2024, and an Enviro100EV for international markets was also in development as of November 2023.

Orders
The Stagecoach Group was the launch customer for the Enviro100EV, with an order for 20 of the type announced in November 2023 intended to have twelve Enviro100EVs delivered to Stagecoach West Scotland and the remaining eight delivered to Stagecoach East Scotland in early 2024. A further ten Enviro100EVs were ordered by the group for delivery between 2025 and 2026, intended for Stagecoach subsidiaries in England which have received central government funding from the Zero-Emission Regional Bus Areas (ZEBRA2) scheme, and 24 Enviro100EVs were ordered by Stagecoach London for delivery in 2025, these being the first Enviro400EVs to be sold to a TfL bus contractor.

The first independent operator to order an Enviro100EV was Shuttle Buses of Kilwinning, who ordered a single example in December 2023. A demonstrator Enviro100EV was also evaluated without carrying passengers on Guernsey in April 2024.

Enviro100AEV
The Enviro100AEV is an SAE Level 4 autonomous variant of the standard Enviro100EV equipped with Fusion Processing's CAVStar Automated Drive System, which was first developed on the larger Alexander Dennis Enviro200AV conventional diesel bus. The first Enviro100AEV was ordered by Stagecoach East Scotland for service on CAVForth2, an extension of the original CAVForth scheme operated by five Enviro200AVs towards Dunfermline city centre via the Forth Road Bridge. Three Enviro100AEVs are to be delivered to Stagecoach East in late 2024, which are intended to enter service on the Cambridge Connector network in early 2025.
