The Mercedes-Benz Citaro is a single-decker, rigid or articulated bus manufactured by Mercedes-Benz/EvoBus. Introduced in 1997, the Citaro is available in a range of configurations, and is in widespread use throughout Europe and parts of Asia, with more than 55,000 produced by December 2019.[1]
The first generation Citaro was launched in 1997, as a successor to the Mercedes-Benz O405.[2]
In 2005, an updated version of the Citaro to coincide with the introduction of Euro IV- (and later Euro V- and EEV-) compliant engines. Apart from minor technical alterations, mainly to accommodate the new generation of engines, the external design received a facelift to give the buses a less angular look, with internal panelling altered accordingly. Production of the old model ceased by autumn 2006.
In 2006 the Citaro received a much more substantial facelift, which can be seen from the outside by a revised front and rear design (analogous to the recently introduced low-entry buses). The hitherto characteristic feature of the first series, the "washboard trim" on the front of the vehicle, which was also available as a front advertising area and smooth surface without Mercedes star, accounted for a somewhat rounded front baffle. The lateral sweep of the front turn signals was reversed.
In May 2011, the second generation Citaro, referred to internally as the C2, was launched.[3] From 2012, the C2 could also be equipped with Euro 6 engines. The C2 versions of the Citaro LE models were the last to be presented, at Busworld Kortrijk in October 2013.[4]

Specifications
Citaro CNG 1st generation facelift
Operators are able to choose between two different front stylings: the standard design features an angled destination display, like a roof dome, and is primarily marketed for urban buses, while a version with a one-piece windscreen covering the destination display also is available and is primarily intended for interurban use. However, all models are available with either version.
With the introduction of 2nd generation Citaro, the front destination display was slightly enlarged, which juts a bit out of the vehicle roof. As a result, Mercedes-Benz designed a small fairing at both sides of destination display. This fairing is available on all models by default. Later, after the introduction of Euro VI version, which results a complete structural change in engine compartment, also the rear destination display was enlarged and added with a fairing. However, afterwards, customers are also able to order a front display without fairing, whether urban or interurban versions.
Other customizations include the number and type of doors as well as the interior layout. Two types of seats are offered as part of the standard range, again with a basic model for urban use and an enhanced version for longer-distance routes, although both also are available on all models.
Aside from the usual diesel engines, the Citaro is also available with a powerful Euro VInatural gas engine M936G rated by 222kW. It can be optionally combined with the new hybrid system of Mercedes-Benz, which helps to save more fuel and lower emissions.[7]
As a one-off, German operators üstra of Hanover and LVB of Leipzig took delivery of a batch of Citaros bodied to a special design by James Irvine for Expo 2000. Leipzig's vehicles were lent to Hanover for the duration of the exhibition, but subsequently returned to normal service in their home city. All other Citaros bodied by Mercedes-Benz were to standard designs, however a number of chassis were bodied by independent manufacturers, most notably Hess of Switzerland. However, the Citaro has more recently only been sold as a complete product.
In 2007 the workshops of the Szeged (Hungary) bus operator SZKT converted a regular Citaro to a trolleybus. As of April 2010, five such buses are already serving as a trolley and more examples are in preparation in the near future.[8]
In 2009, the Centre of Ambulance Services in Dubai took delivery of three Citaros, which had been modified to become the world's largest ambulances.
In 2010, the French city Rennes ordered a longer version of the Citaro, the Citaro M, which is 13 meters long with an urban arrangement. 15vehicles were built over the chassis of the Setra S416NF.
Hydrogen fuel cell version
Citaro FuelCell Hybrid 1st generation facelift at IAA Hannover 2010
Even though the usual Citaro models are powered by diesel or natural gas, there is also a hydrogenfuel cell-powered version, designated Citaro BZ or O530BZ (BZ stands for "Brennstoffzelle" in German, or "fuel cell" in English). During the combustion process, only water steam are produced, so the vehicle is very environmentally friendly. The hydrogen tanks are located in the roof, which results an increased vehicle height at 3.68m (12ft 1in). These buses have 3 doors, low floor configurations, and are capable for a top speed of 70km/h (43mph). About 35 of these buses have been in service in a variety of different world cities in order to test the feasibility of hydrogen fuel cells in numerous countries or continents (including UK, Australia and China), different operating circumstances and different conditions, especially weather conditions.
Hybrid electric version
The Mercedes-Benz Citaro G BlueTec Hybrid is a series-hybridarticulated bus with a compact 450kg, 4-cylinder, 4.8-litre, 160kW, Euro4 OM-924LA diesel engine providing power for a roof-mounted 19.4kWh lithium-ion battery pack, and four 80kW electric wheel hub motors located on the centre and rear axles. (Contrast a conventional bus diesel engine: 6-cylinder, 12-litre, 1,000kg.) The battery pack is also charged by regenerative braking (recuperation). The manufacturer anticipates fuel consumption 20% lower than conventional diesel Citaros. [9][10][11] In 2010, selected bendy buses were delivered in hybrid version to Wuppertal, Stuttgart, Krefeld, Hamburg and Mülheim. Other buses were also delivered to Essen, Duisburg, Munich, Mainz, Hamburg and Rostock are also in the rigid versions. The Dresden and Leipzig also delivered their Citaro hybrid buses in 2011.[12]
Eventually, Daimler decided to not to upgrade BlueTec Hybrid variants to second generation of Citaro. Instead, in 2017, they launched Citaro Hybrid variants of Citaro (diesel) and NGT, which uses mild hybrid drive, much cheaper to manufacture than BlueTec Hybrid drive. It uses 14kW, disc-shaped electric motor mounted between combustion engine and transmission for energy recuperation and can provide a torque of up to 220 Nm.[13]
Battery version / eCitaro
A battery-powered ASEAG Aachen Citaro G (1st generation facelift)
Since 2015, Aachen Transport runs a battery-powered Citaro articulated bus as a test in scheduled operation. The vehicle was converted in 2014 from a hybrid bus to a battery bus. They removed all diesel components and installed 1300 traction batteries with a total capacity of approximately 180 kWh. The axle loads remained unchanged. The vehicle has four wheel hub motors with 60kW continuous power on the second and third axle and has a range of more than 50 kilometres (30mi). The conversion was carried out as part of the EU project Civitas (Cleaner and better transport in cities) and was funded by the Aachen Transport Association to 75 percent. The costs for the hardware (e.g. batteries) amounted to approximately 700,000 euros.
Mercedes-Benz tested prototypes of the Citaro with full electric drive. The bus features a modular battery pack design and use the same electric wheel hub motors as the Citaro G BlueTec Hybrid. It was launched at the IAA Commercial Vehicles show in Hanover in September 2018[14][15] as eCitaro. It uses modified bodywork of standard Citaro with front adopted from Daimler's concept Future Bus. It was first launched as 12 m solo bus. Later, an articulated 18 m version of eCitaro (also known as eCitaro G) was added to offer.
On 15 November 2018, the first series of eCitaro was delivered to its first customer: Hochbahn AG, a public transport company in Hamburg, with a total of 20 at last. In year 2019, more customers started operating eCitaros, including Rhein-Neckar-Verkehr GmbH (RNV), Berliner Verkehrsbetriebe (BVG), Zugerland Verkehrsbetriebe (ZVB), and Bus Ostschweiz (BOS). This was also followed with orders from Verkehrsbetriebe Hamburg-Holstein (VHH) with 16 buses, ESWE Verkehrsgesellschaft mbH from Wiesbaden with 56, and ÜSTRA from Hannover with 48. Mercedes-Benz also received orders from foreign countries, which contains Luxembourg, Norway, and Sweden. In addition, the eCitaro has been crowned to City Bus of the Year 2019 in Spain on 11 February 2019.[16] In 2021, the national bus operator of Hungary, Volánbusz ordered 40 eCitaros,[17] and in 2023, Transdev Blazefield in the United Kingdom ordered 35 eCitaros for their Harrogate Bus Company and Keighley Bus Company subsidiaries,[18][19] the first 20 of which entered service with the former in November 2024.[20]
In 2023, a version with a Toyota hydrogen fuel cell range extender will be offered,[21] allowing a range of up to 400 kilometres (250mi),[22] compared to 280 kilometres (170mi) for the battery electric model.[23]
On 15 September 2024, Mercedes-Benz launched a shorter 10.63-meter version at the IAA Commercial Vehicles show in Hanover. Called the eCitaro K, it featured a 4,398 mm wheelbase and a turning radius of just 17.28 meters, making it suitable for busy city routes. The eCitaro K is powered by a five high-voltage battery packs with a combined capacity of 491 kWh and delivers a range of 300 km under optimal conditions.[24]
Overhead wire version
A Citaro 1st generation as trolleybus in Szeged, Hungary
Because EvoBus itself does not offer trolleybuses, the transport companies of the Hungarian city of Szeged independently built six second-hand Citaro solo vehicles into trolleybuses between 2006 and 2010. This is expected to save on spare parts inventory - this can be done together with the same diesel buses of the dispenser series - as well as lower acquisition costs compared to standard production trolleybuses. The modified type designation is O-530 Tr12, the six wagons bear the operating numbers T-860 to T-865.
In 2012, two Citaro trolleybuses also went into operation in Polish Gdynia. The cars with the numbers 3053 and 3054 originated from used acquired diesel buses from Berlin, which had been delivered in 2002.
Mercedes-Benz CapaCity (also known as O530 GL) is a large-capacity articulated bus based on Citaro G, which was introduced in year 2007. The 1st generation CapaCity is 19.54m long and can carry up to 186 passengers. It features exactly the same turning circle as that of its shorter related Citaro G (17.94m length) thanks actively steered electro hydraulic fourth axle. The safety is guaranteed by Electronic Braking System (EBS), anti-lock brakes (ABS), acceleration skid control (ASR), and the passenger comfort is improved by independent front suspensions. It is both available with 3 and 4 doors. There are also CapaCitys with BRT-Design, which can be recognized by their changed exterior. These buses are currently in service in Istanbul, Turkey, and Bratislava, Slovakia.[25]
The 2nd generation CapaCity was first presented in year 2014. However, it is the long version "CapaCity L" (21m) which became available at the beginning. The shorter version "CapaCity" with a length of 19.7m was added later. They are all based on the modular system of Mercedes-Benz Citaro. The new feature "Articulation Turntable Controller" (ATC) prevents additionally from jackknifing. CapaCity L can carry 191 passengers with standard equipment, CapaCity 182 passengers. They are offered with four doors by default, but with "Metro Package", CapaCity L is also available with five doors, which is better constructed for BRT services. According to Daimler, CapaCity L is the diesel powered urban bus which uses the least fuel per passenger space.[26]
Conecto
Conecto 3rd generation at TransExpo 2016
In year 2007, the 2nd generation Conecto was presented and is both available as standard 12m and articulated 18m version. They are however only available with 3 doors (solo version) and 4 doors (articulated version). Unlike its predecessor as an independent model series (a step-entrance bus derived from O405, model designation O345), it is a technically simplified version of Citaro or Citaro G, with low floor configuration and vertical engines. It is recognizable with the changed exterior design and small differences in interior's design in opposition to Citaro and is mainly sold in eastern Europe, the Middle East and west Asia. The 3rd generation is, since 2018, also sold in Italy (when low-floor Conecto was never officially sold before).
Like previous step-entrance Conecto models, the low-floor Conecto is also produced at Mercedes-Benz Türk factory in Istanbul, Turkey.
In September 2016, the 3rd generation Conecto was presented in Warsaw, Poland. Several improvements were done for the new Conecto, as well as driving safety, passenger comfort, handling and Euro 6 engines, while the operation costs still stay low. Examples for high standard of safety are Electronic Stability Program (ESP) on solo versions and Articulation Turntable Controller (ATC) on articulated versions. Conecto and Conecto G NGT powered by natural gas are also available for the first time. Like the 2nd generation, the 3rd generation Conecto is solely available with 3 doors (solo version) and 4 doors (articulated version).[27] In 3rd generation Conecto, only Euro VI-compliant engines are available (OM936 in 12 m, OM470 in 18 m and M936G in gas versions); the 2nd generation Conecto, with Euro V-compliant engines (OM926LA in 12 m and OM457LA in 18 m models), continues to be marketed in certain non-EU developing markets in eastern Europe, the Middle East and west Asia, alongside the 3rd generation Conecto.
Production
The Citaro is currently built in factories in Mannheim, Germany, and Ligny-en-Barrois, France. It was also built in Sámano in Spain.[28]
The low-cost-variant Conecto is produced by Mercedes-Benz Türk A.Ş. in Hoşdere, Başakşehir, Istanbul, Turkey.

Mercedes-Benz Citaro 1st generation Porto, Portugal
In 2000, Companhia de Carris de Ferro de Lisboa (CCFL) acquired 39 diesel variants of the Citaro, with 3 doors, ZF 5HP502 and OM457hla chassis and, later that year, Sociedade de Transportes Colectivos do Porto (STCP) bought 75 bodywork-based Citaros, with Salvador Caetano CityGold bodywork, OM906hla chassis and Voith D851.3 gearbox, the only series in the world with a 3-speed gearbox. Afterwards, Transportes Colectivos do Barreiro (TCB) and Serviços Municipalizados dos Transportes Urbanos de Coimbra (SMTUC) purchased (since 2001) this model, the case of the first one between the Euro 2, Euro 3, Euro 4 and the Facelift versions, and the second company just the Euro 2 and Euro 3 variants. Both companies also acquired used Citaros, with TCB purchasing four ex-De Lijn vehicles with Euro 3 and SMTUC with a 1997 ex-Hochbahn Citaro (previously owned by Linhares, and also the first used Citaro to Portugal), four ex-Nobina with 3-door and anti-fire system (one already out due to fire) and one with vertical engine, originally a temporary bus, but since 2021 as theirs. In 2022, three Citaro Facelift, originated from TCB after staying out of service for a few years, along with five Volvo B7RLE with Marcopolo Viale Midi buses, both vehicle types from 2009, were purchased for additional service in Coimbra. These vehicles were bought with money originally used to buy a private vehicle for the city council, and they came in a very good condition, although their Voith gearbox have their reatrders always set off, since TCB did disable those on their buses with Voith. Besides the ex-Hochbahn Citaro in Linhares, Rodoviária de Lisboa purchased the Uberland variant of the Citaro, being the second vehicle as second hand purchase. In 2004, STCP tested three Citaro Fuel Cell models for two years, part of the CUTE project for the hydrogen tests through some European countries. Along with those, three Euro 3 Citaros were offered to the company to complement the Fuel Cell tests. One of the hydrogen buses is saved as part of a possible museum (this one has its engine removed) and two of the Citaros are still in circulation (one of them was burned down caused by the engine in December 2016). Since 2008, CCFL purchased the articulated variant of the Citaro Facelift (Citaro G) in two gearbox segments: Voith Diwa 5 and ZF EcoLife. These ones allowed to replace the older Volvo B10M articulated buses from 1991 through 1993 (20 at 2008 and 30 at 2010). In 2010, Empresa de Transportes Gondomarense bought five Citaro K (midi variant) for bus lines with small numbers of passengers. Since then, various Citaro models were second hand buses from Spain and Germany, mostly. In 2018, part of the PO-SEUR project from the Portuguese Government, CCFL acquired 40 Citaro C2G NGT (natural gas) buses to replace the 1995 and 1997 Volvo B10M articulated buses, along with 125 CaetanoBus bodied MAN 18.310 CNG. Besides these ones, Scotturb also acquired 1+20 Citaro C2K, 10 of them are hybrid, for the Circuito da Pena line. This is also from the time when second hand Citaro C2 are put in circulation, like in Rodoviária de Lisboa having 2013 C2 ex-Dr. Richard, from Vienna. In 2022, Área Metropolitana de Lisboa (AML) offered 633 Conectos, 157 Intouros and 50 Citaros (all with Euro 6 engines and Voith Diwa 6 gearbox). Maia transportes, an operator based in Portuguese city, Maia, in Porto, also bought some citaros second handed from Germany. Maia transportes also has 2 ex-Rodoviaria de Lisboa Citaro's Ü.
Malta
In 2011, Arriva Malta recived 81 ex-London Citaro C1 for service on busy urban routes and semi-express routes, these only ran for just about two years though, as the Government of Malta instructed the then operator to retire the bendy busses from service. In early 2015, the new operator Malta Public Transport loaned 25 ex-Heathrow airside Citaro C1 facelifts for use as city busses from Dawson Group. In early 2020, these busses were taken out of service due to demanded fleet reduction because of the COVID-19 pandemic. Nowadays, 10 of these busses are being used as driver trainers, some returned back to the UK, and others are being used as school busses in Cyprus
Italy
Citaro 1st generation in Rome, Italy operated by ATACCitaro C2 operated by MOM in Treviso, Italy.
In 2001, ATAC of Rome ordered 183 Citaro MU interurban model with a blue livery and two doors.[39] This was followed by 301 Citaros urban and suburban model in the normal ATAC grey livery with 2 and 3 doors, in 2004.[40][41] They operate on many routes, including 63, 88, 98, 443, 559, 775 and 881 and many lines around Ostia. ATAC have also introduced 100 new Citaro C2 Hybrid 12m buses entering service in June 2021.[42]
Outside of the capital, ATM of Milan took a delivery of 112 Citaro G bendy buses (in late 2008).[43][44] These are fleet numbered 2901-2984 (4 door model) and 1300-1327 (3 door model) and are mainly seen on routes 70, 73, 94 (2900-2984), 727 and 729 (1300-1327). This was followed by a batch of 2 Citaro G Hybrid in 2011 (2590 and 2591),[45] only allocated to route 94, as well as 3 Citaro Hydrogen 12m in 2012 (2000 to 2002),[46] allocated to route 84. More Citaros (C2 Hybrid 12m) are currently being delivered to Milan.[47]
In 2008, ANM of Naples took delivery of 44 gas powered Citaro Facelift CNG 12m TPLITALIA.IT. These currently run on routes R2 and 151, but can often be seen on other routes operated from the Via delle Puglie depot (such as 601 and R5). Previously, some of these were branded for the ALIBUS route (Airport to City Centre) route until late 2018, when they got displaced by a new fleet of MenariniBus Citymood 10m buses. The buses were supplied by a regional order by Campania which included a total of 58 buses being ordered. The other 14 went to BusItalia of Salerno (at the time CSTP), fleet numbered CITA01-CITA14 TPLITALIA.IT. Once again by a regional order, a further 20 Citaro K C2 Euro 6 were delivered to Naples, fleet numbered N201 to N220.[48]
Citaros are also operated in Venice (ACTV), Trieste (Trieste Trasporti), Cagliari (CTM and ARST) and Bologna (TPER), among other cities. Some of these companies also run Citaro U interurban buses.
Greece
In 2007, Thessaloniki local bus operator OASTH introduced 28 Citaro G buses, with 14 more coming in 2012. In 2009, a 12 meter Citaro was ordered for the cultural route of Thessaloniki. It is equipped with screens that display information about landmarks and comes with a microphone for the tour guide to speak. The citaro is also widely used in other cities of Greece. From 2020 to 2023 both Athens and Thessaloniki have rented used Citaro buses from PAPADAKIS BROS S.A. that were previously owned by several european bus operators including Connexxion, Qbuzz, BVG and more.
In 2003 and 2004, four Citaro Gs caught fire, although there were no casualties involved. One was burnt on its delivery journey. Mercedes-Benz did address the problem, though the buses were withdrawn for some time which the saw the brief return of the just-retired AEC Routemasters. Unfortunately, the fires are said to have marred the reputation of articulated buses in the United Kingdom, and some people nicknaming them Chariots of Fire.[52] The final Citaro G in London was withdrawn in December 2011.[53][54] Eighty-one of Arriva London's examples were exported for use with Arriva Malta.[55]
The RATP Bus Network of Paris operates 426 Citaros of which 349 are standard, 12m length and the other 77 are 18m length bendy buses.[64][circular reference]

In 2010, Keisei Bus ordered 15 articulated O530G Citaro G buses, primarily for service in east Tokyo.[67]
SMRT Buses trialed a Euro V demonstrator unit in 2010,[68] which proved to be successful The trial bus was registered SMB136C and kept by SMRT after the trial concluded. As of January 2025, SMB136C serves as a training bus under SMRT's Woodlands Depot. An additional 10 buses were purchased with a follow-up order of another 40. These buses were registered SMB139U - SMB188C, with slightly different specifications from that of SMB136C.
In 2010, SBS Transit had made an initial purchase of 300 buses to replace several of the remaining Volvo B10M Mark III, as well as a few Volvo B10M Mark IV (Duple Metsec and Walter Alexander Strider).[69] Additional orders were being made to replace all Volvo B10Ms, with another order of 450 (increased to 474) in 2012[70] and a further 250 (increased to 330) in 2014.[71]SBS Transit technical and interior specifications are quite different from that of SMRT Buses.
By 2017, a grand total of 1,155 Mercedes-Benz O530 Citaro buses have been registered under SBS Transit, SMRT Buses, Land Transport Authority’s Bus Services Enhancement Programme (BSEP) and Bus Contracting Model (BCM). Almost all public bus routes utilise O530 Citaros, with all public bus operators (including SMRT Buses) operating Citaros built to SBS Transit specifications.
In 2022, SBS Transit had redeployed several Ulu Pandan Bus Depot MAN NL323F (A22) buses and Mercedes-Benz O530 Citaro buses to replace Scania K230UB (Euro IV) buses on cross-border bus routes (160, 170 and 170X), which are the last diesel single-deck buses to use in Singapore. Those allocated under the Bus Contracting Model were redeployed to SBS Transit.
In March 2020, SBS Transit introduced a Mercedes-Benz O530 Citaro C2 hybrid, registered as SG4004B as part of a 1-year trial and transition to sustainable transport. It was deployed only on routes 93 and 272, and was returned to Mercedes-Benz in 2021, which is due to the subsequent transition to the electric Citaro fleet in the future. SG4004B was eventually exported to the United Kingdom in December 2023.[72]
The Saudi Public Transport Company (SAPTCO), in a joint venture with RATP Group, placed an order for 200 Citaros and 400 Citaro Gs on 16 May 2017. These Citaros are specially adapted for use in the hot desert conditions of Saudi Arabia, with an uprated air conditioning system, circulating air blowers in the doors and double-glazed, darkened side windows. The first vehicles were due for delivery in 2018.[79]

An articulated bus, also referred to as a slinky bus, bendy bus, tandem bus, vestibule bus, stretch bus, or an accordion bus, is an articulated vehicle, typically a motor bus or trolleybus, used in public transportation. It is usually a single-decker, and comprises two or more rigid sections linked by a pivoting joint (articulation) enclosed by protective bellows inside and outside and a cover plate on the floor. This allows a longer legal length than rigid-bodied buses, and hence a higher passenger capacity (94–120), while still allowing the bus to maneuver adequately.
The Mercedes-Benz Sprinter is a light commercial vehicle (van) built by Mercedes-Benz Group AG of Stuttgart, Germany as a large van, chassis cab, minibus, and pickup truck. In the past, the Sprinter had been sold under the Mercedes-Benz, Dodge, and Freightliner nameplates. In the U.S., it was built from complete knock down (CKD) kits by Freightliner. Re-badged and re-engined Sprinters were also sold by Volkswagen Commercial Vehicles as the Volkswagen LT and the Volkswagen Crafter. They are now primarily marketed by Mercedes-Benz.
The Mercedes-Benz O305 is a single deck, double deck or articulated bus manufactured by Mercedes-Benz in Mannheim, West Germany from 1969 until 1988. It was built as either a complete bus or a bus chassis and was the Mercedes-Benz adaptation of the unified German VöV-Standard-Bus design, that was produced by some different bus manufacturers including Büssing, Magirus-Deutz, MAN, Ikarus, Gräf/Steyr, Heuliez, Renault, and Pegaso. The O305 was designed for use as a single-decker bus, however it was later redesigned to accommodate double-decker bodies.
Mercedes-Benz has been producing buses since 1895 in Mannheim in Germany. Since 1995 Mercedes-Benz buses and coaches are known by the brand name of Daimler Buses, a wholly-owned subsidiary of Daimler Truck.

The MAN Lion's City is a range of low-floor and low-entry public buses built by German truck and bus manufacturer MAN Truck & Bus since 1996 primarily for the European market, but is also available in chassis-only variants worldwide. The name Lion's City has been used since 2006, when MAN's public bus models which had been marketed separately were gathered into one range, when also most models received a facelift. The first models to be introduced were the 12-metre low-floor intercity bus NÜ xx3 (A20) in 1996, the 12-metre city bus NL xx3 (A21) in 1997 and the articulated NG xx3 (A23) in 1998. As with former MAN bus models the power-rating made up part of the model name, giving the NÜ-series buses with power-ratings of 260 and 310 hp model names NÜ 263 and NÜ 313 respectively. The main production sites are in Starachowice and Sady in Poland, but the models have also been built in Germany, Turkey and Malaysia. Initially most of the midibus variants were manufactured by Göppel Bus in Augsburg, later Nobitz.
Articulated buses, popularly called "bendy buses," were introduced to London in October 2001 when two Wright Eclipse Fusion bodied Volvo B7LAs were hired from First Hampshire & Dorset, one of which was repainted into First London's red livery, and six Wright Fusion bodied Volvo B10LAs from First Glasgow for a trial on route 207 between Shepherd's Bush and Hayes-By-Pass.
A single-decker bus or single-decker is a bus that has a single deck for passengers. Normally the use of the term single-decker refers to a standard two-axled rigid bus, in direct contrast to the use of the term double-decker bus, which is essentially a bus with two passenger decks and a staircase. These types of single-deckers may feature one or more doors, and varying internal combustion engine positions. The majority of single-deckers have a length of up to 12 m, although some exceptions of longer buses exist. They also typically weigh between 11 and 14 t.
Articulated buses, colloquially known as "bendy buses", were rarely used in the United Kingdom compared to other countries, until the turn of the millennium. This was due to a preference for the double-decker bus for use on high capacity routes. In June 2006, there were over 500 articulated buses in the United Kingdom, although they were still heavily outnumbered by double deckers. The majority of this fleet was used in London, although these buses would be withdrawn by end of 2011.
