The Wright Electrocity was a type of hybrid electric bus built by Wrightbus between 2002 and 2013. The Electrocity was based on DAF/VDL SB120 chassis for most of these buses, except for a single Dennis Dart SLF prototype.

Hybrid electric bus

A hybrid electric bus combines a conventional internal combustion engine propulsion system with an electric propulsion system. These type of buses normally use a Diesel-electric powertrain and are also known as hybrid Diesel-electric buses.

Wrightbus

Wrightbus is a Northern Irish coachbuilder and pioneer of the low-floor bus based in Northern Ireland; it was established in 1946 by Robert Wright and currently run by his son William Wright.

VDL SB120

The VDL SB120 was a low floor light-weight midibus produced from 1999 by VDL Bus & Coach of the Netherlands primarily for the United Kingdom market.

History

Two Electrocity prototypes were initially built in 2002; one based on DAF SB120 chassis, the other based on a Dennis Dart SLF chassis. [1] The bodywork design was similar to the existing Wright Cadet and Crusader, which were also built on DAF SB120 and Dennis Dart SLF chassis respectively, with the addition of battery pods on the roof of the Electrocity being the main difference. The Electrocity was the first bus of its kind to be built, and the prototypes competed mainly with the TransBus Enviro200H.

Wright Cadet

The Wright Cadet was a low floor midibus body built on the DAF/VDL SB120 chassis by Wrightbus between 2000 and 2006. It was sold via VDL dealer Arriva Bus & Coach. Of the 681 produced, 366 were for Arriva subsidiaries including eight for its Netherlands subsidiary. Bus Éireann purchased 35.

Wright Crusader

The Wright Crusader was a single-decker bus body built on Dennis Dart SLF, Volvo B6LE and Volvo B6BLE chassis by Wrightbus between 1995 and 2002.

Alexander Dennis Enviro200

The Alexander Dennis Enviro200 is a bus manufactured by TransBus International and later Alexander Dennis since 2003. The original TransBus Enviro200 design was innovative but ultimately unsuccessful, with few being sold before the introduction of the second generation Enviro200 revived sales for the product from 2006. It was supposed to be positioned in between a minibus and a rigid single-decker bus.

The Electrocity design was facelifted in 2005 to match the updated Cadet design, with the main noticeable change being rounded front headlights. Following the collapse of TransBus International in 2004 and subsequent cancellation of the Enviro200H programme, in February 2006 London Central placed six Electrocitys based on VDL SB120 chassis into service on route 360.

London Central Bus operator in London

London Central is a bus company operating in South London. It is a subsidiary of the Go-Ahead Group and operates services under contract to Transport for London.

London Buses route 360

London Buses route 360 is a Transport for London contracted bus route in London, England. Running between Royal Albert Hall and Elephant & Castle, it is operated by London Central.

Originally equipped with lead-acid batteries and 1.9 litre Vauxhall engines, in 2011 all were rebuilt by Wrightbus with lithium-ion batteries and 4.5 litre Cummins ISBe engines. The hybrid management system was converted from Enova to Siemens. [6] [7] Externally they received larger white pods on the rear roofs to house the batteries.

Vauxhall Motors British automotive manufacturing and distribution company

Vauxhall Motors Limited is a British car brand, which is a fully owned subsidiary of German car manufacturer Opel, which in turn is owned by Groupe PSA of France. Vauxhall's vehicle lineup is identical to that of its parent, Opel, but the Vauxhall brand is exclusively used in the United Kingdom and Isle of Man. Vauxhall is one of the oldest established vehicle manufacturers and distribution companies in the United Kingdom. Its headquarters are in Chalton, Bedfordshire, on the outskirts of North Luton.

Lithium-ion battery Rechargeable battery type

A lithium-ion battery or Li-ion battery is a type of rechargeable battery. Lithium-ion batteries are commonly used for portable electronics and electric vehicles and are growing in popularity for military and aerospace applications. It was developed by John Goodenough, Rachid Yazami and Akira Yoshino in the 1980s, building on a concept proposed by M Stanley Whittingham in the 1970s.

Cummins B Series engine

The Cummins B Series is a family of diesel engines produced by American manufacturer Cummins. In production since 1984, the B series engine family is intended for multiple applications on and off-highway, light-duty, and medium-duty. In the automotive segment, it is best known for its use in Dodge/Ram pickup trucks.

All subsequent Electrocitys were built on VDL SB120 chassis. In 2007, another five were built for Travel London for use on route 129. [8] [9] A single Electrocity was built for London Central in 2008, followed by a batch of six in 2011, to allow for a full conversion of route 360. [6]

Travel London

Travel London was a bus company operating services in Greater London. It was a subsidiary of National Express before being sold in May 2009 to NedRailways. In October 2009, it was rebranded as Abellio London.

These were the last buses to be built to the same Wrightbus design philosophy as that introduced with the Wright Renown in 1997, fourteen years previously; the similarity in the design of the Renown and the Electrocity, at least on the surface with the body design, is evident.

Wright Renown

The Wright Renown is a low entry single-decker bus body built on Volvo B10BLE chassis by Wrightbus in Ballymena, Northern Ireland.

The Electrocity was superseded by the Wright StreetAir in 2016. [10]
