Alexander Dennis Enviro200
The Alexander Dennis Enviro200 (previously known as the TransBus Enviro200) is a midibus that was manufactured by TransBus International and later Alexander Dennis between 2003 and 2018. The original TransBus Enviro200 design was innovative but ultimately unsuccessful, with few being sold before the introduction of the second generation Enviro200 (originally referred to as the Enviro200 Dart) revived sales for the product from 2006. It was supposed to be positioned in between a minibus and a rigid single-decker bus.
The Enviro200 was originally designed to be the replacement for the Dennis Dart SLF chassis and Alexander ALX200 and Plaxton Pointer 2 bodies. The Enviro200 MMC was launched in 2014, eventually replacing the original Enviro200 and Enviro300, which went out of production in 2018 and 2016 respectively.
Over 6,000 Enviro200s had been built as of July 2017.[citation needed] From 2017, the Enviro200 was also marketed in North America. Previously, a licence-built version of the model was built by New Flyer Industries and branded the MiDi.
The first generation Enviro200, then known as the TransBus Enviro200, was unveiled at Coach & Bus 2003 by the vehicle's then-manufacturer, TransBus International. Two diesel demonstrator buses were initially produced for display in 2003.
The first generation Enviro200 was unique in that it had a door both at the front and at the rear of the bus, as such a layout is rare in the UK – most dual-door buses in the UK have a door at the front and another door around the centre of the bus. This door layout was achieved by placing the engine vertically at the rear offside together with other driveline components, which also created a full low floor layout, common on buses in Continental Europe. An "Enviro Pack" mounted to the roof was also incorporated, intended to vent exhaust emissions, noise and heat away from ground level and thus alighting passengers. The design meant that the Enviro200, 2.4 m (7 ft 10 in) and optioned at either 10.5 m (34 ft 5 in) or 11.1 m (36 ft 5 in) long, could hold up to 25% more passengers than a vehicle of equivalent dimensions (10.4 m (34 ft 1 in) long, 2.4 m (7 ft 10 in) wide), with a capacity of 77, with 27 seated.
A single demonstrator of the hybrid variant, the Enviro200H, was produced in 2004 and entered long-term trials in London; however the unconventional engine and door layout, combined with the collapse of TransBus International in 2004, led to the type's commercial failure. As a result, it was the VDL SB120-based Wright Electrocity hybrid electric single-decker bus that was ordered instead by many operators.
Following the collapse of TransBus, the Enviro200 was rebranded as the Alexander Dennis Enviro200 by Alexander Dennis, the successor to TransBus. Only two more first generation Enviro200s were built following the collapse of TransBus, one diesel and one hybrid vehicle, delivered to Far East Travel of Ipswich in early 2007. This pair, and the original London demonstrator, have since passed to Buses Excetera of Guildford.
The first generation Enviro200 was offered alongside the second generation Enviro200 Dart for a time, but received no further orders following 2007 and was retired in favour of the new model. Only five examples were built and only one is known to exist today being the sole hybrid demonstrator for London, SN54 GRU. It was converted to diesel during its working life after its life as a demonstrator and is currently being restored.
