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.
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. 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.
There are three basic versions of the Citaro available in 2019: The standard 12m Citaro, the shorter 10m Citaro K and the articulated 18m Citaro G. Hybrid versions of all three lengths and one full electric version with standard and articulated versions are also available.

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 VI natural gas engine M936G rated by 222 kW. It can be optionally combined with the new hybrid system of Mercedes-Benz, which helps to save more fuel and lower emissions.
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.
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. 15 vehicles were built over the chassis of the Setra S416NF.
Hydrogen fuel cell version
Even though the usual Citaro models are powered by diesel or natural gas, there is also a hydrogen fuel 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. These buses have 3 doors, low floor configurations, and are capable for a top speed of 70 km/h. 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-hybrid articulated bus with a compact 450 kg, 4-cylinder, 4.8-litre, 160 kW, Euro 4 OM-924LA diesel engine providing power for a roof-mounted 19.4 kWh lithium-ion battery pack, and four 80 kW electric wheel hub motors located on the centre and rear axles. (Contrast a conventional bus diesel engine: 6-cylinder, 12-litre, 1,000 kg.) The battery pack is also charged by regenerative braking (recuperation). The manufacturer anticipates fuel consumption 20% lower than conventional diesel Citaros.  In 2010, selected bendy buses were delivered in hybrid version to Wuppertal, Stuttgart, Krefeld, Hamburg and Mülheim. Other buses were also delivered to Essen, Duisberg, Munich, Mainz, Hamburg and Rostock are also in the rigid versions. The Dresden and Leipzig also delivered their Citaro hybrid buses in 2011.
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 14 kW, disc-shaped electric motor mounted between combustion engine and transmission for energy recuperation and can provide a torque of up to 220 Nm.
Battery version / eCitaro
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 60 kW continuous power on the second and third axle and has a range of more than 50 kilometers. 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 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, there are 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.
Overhead wire version
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 sister 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.
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.
CapaCity 1st generation of ASEAG Aachen
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, 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 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).
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).

In May 2018, the Berliner Verkehrsbetriebe (BVG) placed an order for a total of 950 new Citaros: 350 Citaros and 600 Citaro Gs, the first of which was delivered on 20 November 2018. Their engines all meet the Euro VI standard, have low fuel consumption and lower emissions. The BVG also placed a second order for 15 eCitaro, which were delivered in the first quarter of 2019.
The Mercedes-Benz Citaro is also widely used in the rest of Germany. The Hamburger Hochbahn has operated the Citaro since 1997 and has over time, ordered over 1000 in total. DB Stadtverkehr GmbH, a subsidiary of Deutsche Bahn, operates a large number of Citaro or rather Citaro G. They are used in scheduled urban and interurban services in numerous federal states and cities, e.g. Aachen, Düsseldorf, München, Münster, and Stuttgart.
In 2008 to 2013 Bratislava ordered 41 large buses of type Mercedes-Benz CapaCity to replace buses of types Ikarus 435 and Diesel buses Karosa B741. The first bus entered into service in December 2008 on route 96 with evidence number 1999. In 2010 ordered in total 25 buses and in 2012 ordered 15 buses. Bratislava also ordered 1 Citaro CNG with number 2020. Citaro CNG entered to service in November 2009 To February 2018 and today bus Citaro CNG is sold to private owner.
In 2002 Nitra ordered 1 Citaro only for route 28. Original transparents are being replaced in summer 2013 with R&G Mielec.
Connexxion had ordered a total of 255 buses through out 1998 and 2014. That 255 contains the order of the 75 buses in 2019. Besides that they placed another order of 33 Capacity L buses.
The RET, from Rotterdam, has made 2 orders in 2006 and 2008 for a total of 166 Citaro buses. In 2010 they made another small order of 2 hybrid Citaro articulated buses.
Syntus, in the eastern side of the Netherlands, placed two orders for 33 buses. 11 Citaro CNG single buses under the moniker "Gelderland" and 22 articulated CNG buses under the moniker "Veluwelijn"
In 2009, Qbuzz ordered 390 while Connexxion ordered 75. As of 2018 Connexxion under the R-Net moniker took delivery of several CapaCity L models In 2014 Qbuzz ordered another 138 buses for Utrecht under the moniker "U-OV."
In September 2019, STB ordered 130 Citaro Hybrid buses with deliveries to begin in the spring of 2020.
In 2016, Empresa Municipal de Transportes de Madrid (EMT Madrid) ordered 82 natural gas versions of the Citaro, known as the Citaro NGT. The following year, it placed an order for a further 314 buses, and in 2018 it placed another order for a further 276 buses, for a total of 672 buses, all of which are due to enter service by 2020.
In 2000, Companhia de Carris de Ferro de Lisboa (CCFL) acquired 40 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, listed as a temporary bus. 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 compelement 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 2009, CCFL purchased the articulated variant of the Citaro Facelift (Citaro G) in two gearbox segments: Voith Diwa 5 and ZF EcoLife. TTese ones allowed to replace the older Volvo B10M articulated buses from 1991 through 1993. 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 some Citaro C2K, half 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 2001, ATAC of Rome ordered 183 Citaro MU interurban model with a blue livery and two doors. This was followed by 301 Citaros urban and suburban model in the normal ATAC grey livery with 2 and 3 doors, in 2004. They operate on many routes, including 63, 88, 98, 443, 559, 775 and 881 and many lines around Ostia. ATAC will also be taking a delivery of 100 new Citaro C2 Hybrid 12m buses, scheduled to enter service in 2021.
Outside of the capital, ATM of Milan took a delivery of 112 Citaro G bendy buses (in late 2008). 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), only allocated to route 94, as well as 3 Citaro Hydrogen 12m in 2012 (2000 to 2002), allocated to route 84.
In 2008, ANM of Naples took delivery of 44 gas powered Citaro Facelift CNG 12m . 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 .
Right-hand drive versions of the articulated Citaro G were introduced in London on 2 June 2002, on routes 507 and 521. They were eventually used on 12 routes across London, and were operated by various Transport for London operators including East London, First London, London Central, London General and Selkent.
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.
The final Citaro G in London was withdrawn in December 2011.
Rest of the UK
Solent Blue Line in Southampton received 10 Citaros in 2006. They were branded in the Bluestar livery and were mostly seen on the services 8 and 9 to Hythe and the waterside. Others could be seen in the colours of sister companies in the Go-Ahead group such as Oxford Bus Company, Go North East, Brighton & Hove, Plymouth Citybus, Southern Vectis and Wilts and Dorset including the 'Pulse Line' (Salisbury) and 'More' (Bournemouth and Poole) branded services.
Between 2006 and 2009 Uno of Hertfordshire took delivery of a total of 22 12m Citaros, as well as running a small fleet of articulated 18m Citaros on their Shuttle service in Hatfield.
Kinchbus of Loughborough became the first British bus company to order Euro 6 Citaro C2s. 8 entered service in late 2014 (with a further three in late 2017) on their Skylink route from Leicester to East Midlands Airport and Derby. However, the buses have now been withdrawn due to reliability concerns, with all transferring to McGill's Bus Services in Scotland. The previous buses have been replaced by ADL Enviro200 MMCs. Sister company trentbarton had also purchased six Citaros in 2009. After a fire destroyed one of them, Kinchbus inherited the remaining buses, which remain in service as of 2020.
In 2013 Cardiff Bus received 20 Euro 5 citaros. Then again in 2015 they received 10 Euro 6 citaros then a further 10 in 2017, bringing the total in the fleet to 40.
Finally, Yourbus operated a fleet of 31 Citaros (16 62-registered and 15 64-registered). Given Yourbus' liquidation in October 2019, they have since been sold on to other companies. Most of these are currently operating at Diamond Bus North West.
In year 2006, 3 hydrogen-fuelcell-powered Citaro buses began their test launch in Beijing, China. They ran on an 18.2 km long ring-line, which contains 11 stations and uses Summer Palace North Gate as departure/terminal station. The operating hours ranged from 9am to 3pm, the bus came approx. every 40 minutes. Each ride costs 2 CNY. During the launch, these 3 Citaro left a very positive impression to the passengers.
SMRT Buses trialed a Euro V demonstrator unit in 2010, which proved to be successful and an additional 10 buses were purchased with a follow up order of another 40. In 2011, SBS Transit made an initial purchase of 300 buses, before following up with another order of 450 (increased to 474) in 2012 and a further 250 (increased to 330) in 2014. By 2017, a grand total of 1,155 Citaro buses have been registered, with some allocated to Tower Transit Singapore and Go-Ahead Singapore under the Bus Contracting Model.
In March 2020, SBS Transit introduced a Citaro hybrid with C2 bodywork, registered as SG4004B as part of a 1-year trial. It is currently deployed on Service 93, one of the 2 authorised routes which the bus is permitted to operate on, along with Service 272, which it was previously deployed on.
In Australia, between September 2004 and September 2007, Transperth trialled three hydrogen powered O530BZs. One was preserved by the Bus Preservation Society of Western Australia with the other two scrapped at the end of the trial. In 2016, Brisbane Transport trialled a Citaro demonstrator.
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.
