Chronology

The Alexander Dennis Enviro200 Dart is a bus manufactured by Alexander Dennis since 2006 as a replacement for the Dennis Dart SLF chassis and Plaxton Pointer body. The Enviro200 Dart is also manufactured and marketed in North America by New Flyer as the MiDi.[1]

A new updated model was released in 2014.[2]

Design[edit]

Kowloon Motor Bus Enviro200 Dart, with modified frontal design to meet the ECWVTA regulations

The Enviro200 Dart, as it was originally known, was launched by Alexander Dennis in August 2006. The bus is available in five lengths, ranging from 8.9 metres to 11.4 metres.

Unlike the innovative but unsuccessful TransBus Enviro200, the chassis of Enviro200 Dart (also known as the Dart 4[3]) retains the conventional rear-engined layout of the Dart, and is offered with a choice of four or six-cylinder Cummins ISBe Euro IV engines with a range of transmission options, and features new front and rear axles.

It offers the same seating capacity of the Pointer, but with more 'fixed' seats rather than 'tip up' for each length. The vehicle features integrated chassis and body multiplexing, and cantilevered seats.

Externally, the bus features the same front panel as the double-deck Enviro400, projecting a "family look" onto the two models. The Enviro200 Dart chassis is also available with East Lancs Esteem and MCV Evolution bodywork.

In February 2007, the body of Enviro200 Dart became available on MAN 14.240 chassis, this is to give the option of EGR emissions reduction as some operators prefer this technology to the Cummins' SCR.

In August 2007, due to significant orders for the Enviro400, Alexander Dennis announced that the production of Enviro200 bodywork would be moved from its's plant at Falkirk to the recently acquired Plaxton factory at Scarborough. This meant that the Scarborough factory would once again be producing the bodywork for the Dart chassis, and producing the bodywork for the MAN 14.240 at the same time as the Plaxton Centro and Enviro200 bodies.

In 2008, Alexander Dennis unveiled the hybrid-electric powered version of Enviro200 Dart (known as the Enviro200H, not to be confused with the TransBus Enviro200H which was unveiled in 2003) using BAE Systems's HybriDrive series drive system with the Cummins ISBe 4-cylinder engine fitted for power generation.[4]

In early 2011, the Enviro200 was modified in order to meet the European Community Whole Vehicle Type Approval (ECWVTA) regulations.[5] Apart from the change of body length options, other modifications include:

  • Space was reserved below the headlamps for installation of daytime running lamps.
  • Offside emergency door, which was no longer mandatory for dual-door version, was relocated from the rear to the centre.
  • New rear bumper was used, with lowered position for the registration number plate.
  • New rear engine cover was used, without the model name 'ENVIRO200'.

The orders[edit]

Over 4,000 Enviro200s have been built.[6] While most have been for British operators, examples have been exported to Australia, Hong Kong, New Zealand and Spain.[7][8][9]
