The Enviro200 MMC bodywork is also available as an all-electric bus, known as the Alexander Dennis Enviro200EV, built on a BYD Auto battery electric chassis.

Notably, some Enviro200 MMCs have also been modified by Fusion Processing to be used as the basis for the first driverless bus trials in the United Kingdom.

Through financial difficulties at the various parent companies, production of the Dart SLF passed first to TransBus International in 2001 and subsequently to Alexander Dennis in 2004.

Alexander Dennis unveiled the Enviro200 MMC (short for Major Model Change) at the Euro Bus Expo in Birmingham in November 2014.

[4] The first production examples of the Enviro200 MMC entered service with National Express West Midlands in 2015, the operator having ordered 50 of the type.

[7] Twelve more were delivered to Bluestar in 2016,[8] followed by a third batch in 2019, some of which had air filters mounted on the roof following successful trials in Southampton.

[citation needed] Arriva North West, meanwhile, began taking delivery of 56 Enviro200 MMCs for use on the Liverpool City Region's franchised Metro services from November 2024 onwards.

[61][62] A pair of Enviro200 MMCs were delivered from stock to Rotala subsididary Preston Bus on short-term notice in September 2024.

It has been produced since 2015 by the British company Alexander Dennis in partnership with the Chinese electric vehicle manufacturer BYD Auto.

[73] The first autonomous bus trial in the United Kingdom commenced in mid-2019, with an Enviro200 MMC modified with SAE Level 4 autonomous software from Fusion Processing able to operate in driverless mode within Stagecoach Manchester's Sharston bus depot, performing tasks such as driving to the washing station, refuelling point and then parking up at a dedicated parking space in the depot.

A passenger-carrying driverless bus service named CAVForth commenced operations on 15 May 2023 using a fleet of five Enviro200AVs built to the same specifications as the Manchester trial vehicle on a 14 miles (23 km) Stagecoach East Scotland park-and-ride route across the Forth Road Bridge, from the north bank of the Forth to Edinburgh Park station.

[75][76] The pilot service, partly funded by the UK government's Centre for Connected and Autonomous Vehicles (CCAV), employs twenty personnel recruited by Stagecoach, which includes 'safety drivers' who occupy the cab and monitor the driverless technology as well as 'bus captains', similar to the role of a bus conductor, who will assist passengers boarding the service.
