A. Mercedes-Benz Citaro: world’s first production urban bus with Euro VI emissions rating

- Drive system: two completely newly developed engine families
- Fuel consumption up to 5 percent lower with Euro VI
- Excellent economy thanks to technical finery
- Design: the restyled Citaro rear end
- The exhibition vehicle in detail

The Mercedes-Benz Citaro is extending its lead over the competition with a brand new generation of engines. It is the first regular-service bus to be supplied with power units that already meet the Euro VI emissions standard. It furthermore includes a raft of innovative measures for cutting fuel consumption and CO2 emissions. At the same time, this compensates for the Euro VI technology’s extra weight.

Drive system: two completely newly developed engine families

The engine series for the Citaro have been developed completely from scratch, and comprise the OM 936 and OM 470 in-line 6-cylinder units with displacements of 7.7 litres and 10.7 litres respectively. Both have a Euro VI emissions rating. Another common characteristic is excellent economy resulting from their durability, efficient consumption of fuel, AdBlue and engine oil, as well as the long service intervals for the particulate filter in the Citaro of 120,000 km or two years.
In practice, the engines stand out for their spontaneous response from standstill and impressive power output combined with smooth running. The high torque that comes online from very low rev speeds ensures effortless and economical power delivery from just above idling speed.

Thanks to the beefy performance on tap, it was possible to lengthen the final drive ratios compared to the previous engines in almost all cases. The result is a considerable reduction in both engine speed and noise levels. The optimum shift points furthermore occur at low engine speeds, enabling a smooth, fuel-efficient driving style with a smaller number of gear changes for even greater comfort.

Technical features of the new engines

A highly efficient combustion process using common-rail injection forms the foundation for clean emissions and low fuel consumption. The high ignition and injection pressures both set new benchmarks, while the system of cooled exhaust gas recirculation brings further benefits, too.
Both engines employ the BlueTec 6 exhaust gas aftertreatment technology from Mercedes-Benz: here, a closed particulate filter is combined with the successful SCR system from Mercedes-Benz to optimum effect. 

The new OM 936 in detail: compact and powerful

The refined features of the OM 936 include VCP (Variable Camshaft Phaser), as the first adjustable exhaust camshaft to be fitted in a diesel engine is known. This aids particulate filter regeneration by modifying the valve timing on the exhaust side. The six-cylinder unit comes in two power ratings.

Output / Torque

220 kW (299 hp) at 2200 rpm / 1200 Nm at 1200 rpm
260 kW (354 hp) at 2200 rpm / 1400 Nm at 1200 rpm

The in-line six-cylinder engine is available for the Citaro in a horizontal variant (OM 936h), which comes in both power ratings and is tailored to regular-service bus operation. Although the basic engine remains the same, there is still a great deal of engineering work involved as the entire engine periphery has been purpose developed for such applications.

The 220 kW engine can also be ordered in a vertical variant. The second power rating delivering 260 kW is initially only available for the vertical engine on the Citaro LowEntry model, and cannot be specified for the regular rigid version as yet.

The OM 470 in detail: light but powerful

The new OM 470 is based on the heavy-duty engine series. Weighing just 990 kg (DIN 70020-A), it is perfectly suited to use in articulated vehicles. The standout feature of the vertically installed OM 470 engine is the unique and highly flexible X-PULSE common-rail system from Mercedes-Benz with fully electronic control and hydraulic pressure boosting.

The new OM 470 is designed to power articulated buses that operate in challenging topographical conditions. It comes in a choice of two output and torque ratings:

Output / Torque

265 kW (360 hp) at 1800 rpm / 1700 Nm at 1100 rpm
290 kW (394 hp) at 1800 rpm / 1900 Nm at 1100 rpm

Power is transferred to the wheels via an automatic transmission with torque converter. There is a choice of units manufactured by Voith and ZF, which come in the very latest version for the Euro VI emissions rating. With their torque converter design, they are ideally geared towards the low rev speeds of the new engines.

Fuel consumption up to 5 percent lower with Euro VI

Despite the Euro VI rating and the extensive exhaust gas aftertreatment technology that accompanies it, the new Citaro actually succeeds in once again undercutting the fuel consumption figures of its economical Euro V predecessor. Measurements taken in practice indicate an average fuel saving of up to 5 percent.

Excellent economy thanks to technical finery

The development team for the new Citaro really pulled out all the stops to assure it of outstanding economy. Take, for instance, the regular-service bus’s fuel-saving recuperation module: the electrical power generated without using fuel during overrun phases is stored and then used to supply power to auxiliary consumers such as fans, lighting, etc. when the bus is accelerating forward again. The air compressor with two-stage control also features a recuperative operating mode when the engine is overrunning, as it fills the compressed air tanks above the normal level of 10 bar to 12 bar. This excess compressed air can then be utilised by the auxiliary consumers when the vehicle is next accelerating, th
ereby reducing air compressor operating time and, in turn, fuel consumption.

The battery and alternator management systems are networked by CAN bus, allowing them to communicate with one another and distribute the load more evenly. This serves to extend the operating life of these two units. A tyre pressure monitoring system is optionally available for the first time, which indicates the current pressure in the individual tyres as well as providing a warning when fluctuations are detected.

Lowering the entrances at doors 2 and 3 (or 4 on the articulated bus) by 20 millimetres to 320 millimetres increases passenger comfort, shortens the kneeling time and also reduces air consumption – meaning a substantial reduction in fuel consumption, too.

Despite the inclusion of the new generation of Euro VI engines with their exhaust gas aftertreatment technology, the weight of the new Citaro is largely unchanged, meaning no loss of passenger capacity. As a result, the rigid bus offers space for up to 100 passengers, depending on the chosen configuration.

Design: the restyled Citaro rear end

On the outside, it is the slightly raised rear end and tower-style engine arrangement that distinguish the new Citaro with Euro VI emissions rating. Masked by a styling element on the sides, the rear turret is particularly eye-catching, as it gives the Citaro a slightly rounded and dynamic silhouette. The dark-tinted glass service flap on the left of the rear window is yet another distinctive feature.

The lighter engine compartment flap has been redesigned too, with a sandwich construction formed by joining two pressed parts together. The tail light clusters have an unmistakable design and are made up almost exclusively of energy-saving, long-life LED bulbs.
Engine and radiator in tower arrangement

The engine tower at the rear varies in size depending on whether a horizontal (OM 936h) or vertical (OM 936/OM 470) engine is fitted. The radiator above the power unit is positioned far out of the range of any dirt or spray water that is thrown up, as is the engine’s air intake.

The engine tower features a new insulation concept, comprising two layers of sheet metal with the insulation sandwiched in-between. This insulation jacket has a decorative plastic coating on the side facing the passenger compartment.

The new Mercedes-Benz Citaro: characteristic features

The front end of the Citaro has a particularly striking “expression”, greeting its passengers with a friendly smile. The large almond-shaped headlamps and the front end’s rounded forms help to rid the Citaro of the austere appearance that is so typical of regular-service buses. The deep-set side window line gives the bus a transparent appearance. The three-dimensional styling of the glass-fibre-reinforced-plastic wheel arches lends the body added dynamism.

One of the outstanding safety features at the front is the collision protection for the driver in the front end. This, together with the strengthened A-zero pillars and the frame design, means that future European pendulum impact regulations have already been factored into the Citaro. This collision protection has been tested in accordance with the ECE R 29 standard, while the Citaro bodyshell also already meets the ECE R 66.01 standard governing rollover strength, which only comes into effect in 2017.

Lower, well-illuminated entrances

The passenger compartment of the new Citaro has a particularly inviting feel to it. The pleasant experience for passengers begins at the bus stop thanks to the bright illumination of the entrance and exit areas. The passenger compartment itself stands out for its bright and cheerful design.
Light fittings can be supplied for the ceiling’s border section in the new model generation. These LED lamps can be used to create quiet zones and reading corners within the seating area. The good lighting levels reduce the risk of vandalism and increase passenger safety.

Driver’s workstation with perfected ergonomics

The driver’s workstation on the new Citaro takes ease of operation, ergonomics, instrumentation and comfort to new heights. The door to the driver’s cab is hinged at the rear and opens from the front. At the same time, the developers have improved the door’s stowage facilities. The partition screen for the driver’s cab is larger than before and curves further forward, too. Drivers also benefit from a higher seating position that puts them at eye level with passengers who are boarding.

The instrument panel mirrors all the recommendations for the new European driver’s workstation. The new, elegant shape creates extra kneeroom, while its soft-touch surface further adds to the Citaro’s high-class feel. The cockpit comprises large, clearly arranged dials for road speed and engine speed. Between the two dials there is a colour display showing a multitude of supplementary information, which can be operated using the buttons on the steering wheel. The cockpit’s buttons and switches have been positioned based on the latest ergonomic findings.

The comfort and safety-enhancing Citaro chassis

The chassis excels with exceptional comfort and handling safety thanks to the independent front suspension. The Electronic Stability Program (ESP) is being made available in a low-floor urban regular-service bus for the very first time in the new Citaro, thereby taking safety technology for this type of vehicle into a brand new era.

The exhibition vehicle in detail

The three-door rigid bus with vertically mounted engine encompasses a wealth of outstanding features, ranging from the Euro VI emissions rating to the Electronic Stability Program (ESP). Power is provided from the rear by the new OM 936 in-line 6-cylinder engine with a 7.7-litre displacement, an output of 220 kW (299 hp) and maximum torque of 1200 Nm. Power is transferred by the ZF Ecolife six-speed automatic transmission.

Its safety specification, including the Electronic Stability Program (ESP), is exemplary. The chassis is equipped with anti-roll bars, electronically operated level control and roll-and-pitch control. The lighting system is in a class of its own, comprising bi-xenon headlamps, fog lamps with integrated cornering light function and LED daytime running lamps. Cameras monitor the area around the cash register and the door 1 entrance as well as the passenger compartment. There is a 6.5-inch (16.5 cm) screen integrated into the driver’s workstation to monitor what’s happening. LED entrance lights (known as ambient lighting) are placed under the hem section at all three doors to help passengers boarding the vehicle in the dark.

Functionality: the Citaro is driver and maintenance-friendly

The segmented side panelling with easily replaceable components simplifies repairs. The electrically powered pivot-and-slide doors operate rapidly, and remain securely shut when closed. The electrically operated cassette ramp under the vehicle floor at door 2 makes life easier for the driver. The electric pivot-and-slide door at the front is unique, as it allows fast door opening and a generously sized entrance area for passengers.

B. Mercedes-Benz Travego: even safer thanks to Active Brake Assist 2 and Edition 1 is even cleaner thanks to compliance with the Euro VI emissions standard

- Active Brake Assist 2 brakes when it recognises stationary obstacles
- Attention Assist supports the driver's concentration
- An engine from the new BlueEFFICIENCY Power generation
- Automated GO 250-8 PowerShift transmission
- Cockpit revised to the very last detail
- Travego M Edition 1: touring coach for the successful

The Mercedes Benz Travego is strengthening its leading position in the premium high-deck touring coach sector. It now has unique safety features such as Active Break Assist 2 or Attention Assist. At the same time, the Travego Edition 1 is the first standard touring coach which complies with the Euro VI emissions standard.

Active Brake Assist 2 brakes when it recognises stationary obstacles

The second generation of Active Brake Assist is new and unique to the Travego. Until now the risk of a rear-end collision with a slower vehicle travelling ahead caused the safety system to initiate a full brake application. Now though, Active Brake Assist 2 also brakes the vehicle if stationary obstacles, such as an unexpected traffic jam on the motorway, are detected.

The radar-based system scans the lane ahead, covering an area of between 0.25 and 200 m in front of the bus whilst continuously measuring the distance and the relative speed of vehicles ahead or the distance to an obstacle. The radar technology functions reliably in almost all weather and light conditions. Active Brake Assist is active at all speeds up to 100 km/h.

Active Brake Assist is available for all variants of the Travego Edition 1. It is supplied at no further cost, if ordered in conjunction with the optionally available adaptive cruise control.

Attention Assist warns the driver of fatigue

The new Attention Assist, available in the Travego Edition 1 as an option, is just as unique. It registers parameters such as steering angle, speed, longitudinal and lateral acceleration, journey time, control signals and the change of drivers. Attention Assist correlates this data in order to ascertain the condition of the driver. If the data indicates a lack of concentration or the onset of fatigue, a coffee cup symbol appears in the display indicating that a break is necessary.

LED daytime running lights and a tyre pressure monitoring system

Further equipment also increases the safety standard of the Travego Edition 1. The new daytime running lights with LED lamps integrated into the housing of the headlamps are also optional. Special equipment also includes a tyre pressure monitoring system which indicates the pressure of the individual tyres and issues a warning should the pressure deviate from the optimum value. This reduces wear on the tyres, has a positive influence on fuel consumption and prevents dangerous tyre damage.

An engine from the new BlueEFFICIENCY Power generation

The drivetrain on the Travego Edition 1 heralds a new era for touring coaches. This figurehead of Mercedes Benz Buses is the first touring coach to comply with the upcoming Euro VI emissions standard.

The engine in the Travego Edition 1 is a vertically mounted straight six-cylinder from the new OM 471 model series. With 12.8 l displacement, it delivers 350 kW (476 hp) at 1800 rpm. The high maximum torque is 2300 Nm at 1100 rpm.

The engine is equipped with the unique common-rail injection system with pressure booster (X-PULSE). This enables extremely precise fuel injection with cylinder-selective control, high injection pressures of up to 2100 bar and a freely adjustable injection process. This new engine is the prerequisite for low fuel consumption, reduced exhaust emissions and smooth running.

The efficient three-phase engine brake and the asymmetric exhaust gas turbocharger bring about further advantages. The latter provides for the engine's fast response. The torque characteristic of the new engine enables unusually low and fuel-saving engine speeds. The engine achieves a torque of 2000 Nm at around 900 rpm.

The new in-line engines boast low fuel consumption and particularly low emissions. The exhaust system of the EURO VI engines is also equipped with an extremely efficient diesel particle filter which, in the Travego, only needs servicing for the first time at 360,000 km and thereafter only every 240,000 km.

Great cooling performance, no disadvantage to weight

The developers of the Travego Edition 1 have pulled out all the stops. A significantly higher cooling performance is required for the Euro VI. This was achieved by moving the radiator from the left to the right-hand side, shielding the radiator from the engine compartment, additional exhaust air openings on the rear end as well as the use of optimised fans and fan couplings with an improved control range.

To optimise weight distribution, the developers swapped the positions of the fuel tank and batteries, placing the fuel tank in front of the front axle. At the same time the weight of the vehicle was reduced by optimising components. In doing so, an important requirement was able to be fulfilled: Euro VI buses should not exhibit any restrictions with regard to passenger and luggage capacity when compared with previous models.

Automated GO 250-8 PowerShift transmission

In the Travego Edition 1, Mercedes Benz is introducing the new GO 250-8 PowerShift eight-speed bus transmission together with the Euro VI-compliant engines. The fully automated assembly is based on the well-respected GO 240-8 PowerShift transmission still in use in other models.

As usual, drivers profit from the progressive graduation of the transmission as well as even faster and more comfortable gearshifts. A heat exchanger ensures that the oil temperature in the transmission remains constant at an operating level of about 80 degrees. This has a positive effect on oil change intervals. The crawling mode of the transmission is also new. It enables precise manoeuvring simply by using the brake pedal.

The new integrated retarder achieves braking torques of up to 3500 Nm. It uses the engine coolant as a braking and cooling medium. As a result the heat exchanger that was previously necessary and the associated oil change are now redundant.

The practically wear-free and almost maintenance-free clutch is also new. Thanks to a centrically located, pneumatically operated clutch cylinder, mechanical parts such as the clutch release fork, release bearing and clutch force booster are no longer required.

Gears now shifted with a steering-column lever

The gearshift of the GO 250-8 PowerShift transmission is completely new: the joystick in the instrument panel has now been replaced by a steering-column lever. It is used for all functions, but these are all very clear thanks to the unmistakable operation of the lever.

The driver can manually intervene by pulling the lever towards him or pressing it briefly. The retarder can be controlled in the usual manner by moving the lever downwards.

Cockpit revised to the very last detail

In addition to the steering-column lever for operating the transmission, the developers have implemented numerous ideas for optimising the ergonomics of the cockpit for the driver: navigation through the various functions and displays via the new multifunction steering wheel has also been simplified considerably.

The new electronic key is inserted on the left-hand side of the instrument panel. The ignition and the start/stop function of the engine are controlled via a two-stage button. The switches in the cockpit have been rearranged according to their function.

Large, legible instruments

The use of non-reflecting glass for the display instruments is also a new feature. Two large gauges display the speed and engine revs. Two smaller instruments indicate the level of fuel and AdBlue. The driver can also access many other types of information in the centrally located colour display using the steering wheel keypad.

The Travego at the International Motor Show for commercial vehicles (IAA) 2012

The 13 m long, three-axle Travego M Edition 1 on exhibit does not only have all of the technical features of the Travego Edition 1; this is a very special touring coach: it is the team bus for the German men's national football team. Its exterior basic colour of Arachne Metallic matt white, painted door mirror caps and the striking lettering emphasise its special use.

The seating, with 36 Travel Star Xtra seats in Luxline upholstery and with leather covers, provides extraordinary travel comfort. The silver-coloured leather head sections as well as the side folds and curtains in curry contrast with the black seats and backrests. Anyone who wants to put up their tired feet can take up place in the first row of seats which features an electrically adjustable table/leg rest.

Entertainment during the journey is no problem: card players can meet up at the rear of the coach where there are two club tables with face-to-face seats. Those who just want to watch the game have a good view from every seat: there are a total of three monitors located in the front end and in the centre aisle whilst a fourth flat screen (all 19-inch/48 cm) is mounted in the rear. Four subwoofers, located under the passenger seats, guarantee a rich sound from the on-board audio system.

C. Mercedes-Benz Intouro: utmost economy across the board 

- Extremely efficient high-floor rural-service bus
- Proven components from the modular system
- Easy-to-repair long-term construction
- Comfort level of a touring coach
- Powerful, economical and long-lasting engines

Mercedes-Benz completes it range of rural-service buses: the successful Integro will be complemented by the particularly efficient and functional Intouro. Thus, with its broad palette consisting of the Citaro Ü, Citaro LE Ü, Integro, Integro RH and Intouro (which is now available across Western Europe), Mercedes-Benz covers every possible bus requirement from local transportation to inter-city buses, right up to rural regular-service buses.

Extremely efficient high-floor rural-service bus

Intouro stands for an economic high-floor vehicle concept, which is particularly suited to inter-city applications, school bus operations and own account transport requirements. Previously only on offer in Central Europe and in selected Western European countries, the Mercedes-Benz Intouro will now be launched across the whole of Europe.

As a purely high-floor vehicle with a floor height of 860 mm, the Mercedes-Benz Intouro comes directly from the tried-and-tested Mercedes-Benz rural-service bus modular system. With its focus firmly on economy, both in terms of acquisition and running costs, the Intouro impresses with its excellent price-performance ratio. Long-lasting components, robust technology and an equipment level intended primarily for inter-city operation distinguish the Intouro.

Proven components from the modular system

The Intouro scores points with its attractive life cycle costs, from acquisition right through to re-sale. Besides its functional and largely standardised equipment, this is to a large extend thanks to the numerous practically tested components and assemblies adopted from other rural-service buses sporting a star.

Made for everyday operation even under the most demanding of conditions, the Intouro fulfils the special requirements of a long-lasting vehicle made for high mileage. The two-axle rural-service bus is available in two lengths (Intouro 12.14 渀 m length, 6080 mm wheelbase; Intouro M 12.98 m length, 6920 mm wheelbase) and has space for 55 and 59 passengers respectively. Both variants measure 3.36 m in height. Upon request, the centre door can be ordered as a double-wing door.

Both optically and technically, this is a true Mercedes-Benz

Both optically and technically, the Mercedes-Benz Intouro fits perfectly into the Mercedes-Benz bus family. The front end of this attractive rural-service bus, with its individual round headlamps fitted in a dynamic piece of trim, sets itself apart thanks to its taut lines. This impression is further reinforced by the air intake integrated into the front trim panel as well as by the rounded bumper.
The shape of the Intouro is, rather befittingly of its duties, in the first instance, characterised by high functionality. The high, steep integral front windscreen offers an optimal view whilst also leaving enough space for the integration of a large destination display. At the same time, the front windscreen forms the basis for optimum usage of the available space and a sense that the interior is both generous and airy.

Easy-to-repair long-term construction

The flat and easy-to-clean side wall with large seamless bonded side windows in front of thin window pillars is perfectly suited for personalised letterings or advertisements. The rear end mirrors the fact that this bus belongs to the Mercedes-Benz family. The rounded rear window is particularly prominent. The autonomous tail lights frame the engine hatch, which itself takes up the same design idiom as the rear window. The three-part bumper ensures that minor manoeuvring damage can be repaired cost-effectively.

Thin seals on the doors and flaps are proof of a high-quality bodyshell, a feat also mirrored by the cathode-dip-primed body with the best possible level of protection against corrosion.

Economic in acquisition, operation and maintenance

The Intouro impresses with high cost-effectiveness in all areas. Its low weight is absolutely crucial if a large number of passenger seats is to be accommodated. It is equally important for a reduction in fuel consumption in comparison with an identical load. Oil change intervals every 60,000tkm correspond, in usual operation, to a single service interval every year.

For standardised fleet management, a Fleet Management System (FMS) interface is also optionally available. With the FMS, a service provider obtains a comprehensive overview of the technical condition of their Intouro and any current vehicle operating data.

To keep maintenance and repairs simple, the entire front-end flap can be folded down. Just as with the three-part rear bumper, the elements of the front bumper which house the headlamps and indicators can also be replaced individually should they become damaged. Small repairs can therefore be carried out quickly and cost-effectively.

Comfort level of a touring coach

In its segment, the Mercedes-Benz Intouro is also the benchmark in all things comfort. The safe and balanced driving characteristics of the Intouro are based on a chassis which makes use of fully-fledged touring coach technology. This has been adapted to suit the specific requirements of rural transport. The front axle is not only safe and comfortable, it also allows for extraordinary manoeuvrability thanks to its large wheel turning angle (wheel on the inside of the bend: maximum 58 degrees). Accordingly, the turning circle of the Intouro is a mere 20.98 m. Even the longer Intouro M version achieves a comparably good value of 23.12 m.

Spacious and customisable interior

Passengers climb aboard both at the front and middle of the vehicl
e through 900-mm-wide outward-swinging single-wing doors. The centre door is optionally available as an outward-swinging double-wing door with a width of 1380 mm. A lift for disabled passengers is also available.

The passenger area of the Mercedes-Benz Intouro has impressive headroom measuring 2.17 m which affords a pleasant feeling of openness and spaciousness. The "Inter-Star Eco" seats which were specially designed for rural-service buses sit firmly on top of a 170-mm-high platform.
Thanks to a modular system, these high-strength seats can be delivered in different backrest height variants. It isn't just the comfortable upholstery with its pleasant lateral support that is impressive, rather also their optically appealing shape with thin head restraints.

The double seats are fixed at the side in C rails on the wall. This means that the distance between the seats can be changed without great effort. As an option, the Mercedes-Benz Intouro can also be ordered with the particularly comfortable "Travel-Star Eco" seating which offers improved comfort.

Above the passenger seats, optionally available luggage racks can accommodate hand luggage. The grid floor of the luggage racks ensures that no possessions get left behind. Large pieces of luggage fit nicely in the spacious luggage compartment between the axles. Depending on the centre door fitted, the volume of the luggage compartment ranges from 4.5 to 5.0 m³ (Intouro) and 5.5 to 6.0 m³ (Intouro M).

A powerful electronically-controlled heating and ventilation system ensures a homely ambience on board this rural-service bus. The heat distribution within the bus is handled by heating fans. As an optional extra, the Intouro can be equipped with a powerful roof-mounted air-conditioning system with either 26 kW or 32 kW output, depending on the vehicle's engine variant.

Ergonomically designed driver's area, practical stowage compartments

The driver's area of the Intouro rural-service bus is, just like the centre isle, 860 mm above road level. The cockpit is optically styled on Mercedes-Benz touring coaches and is definitely driver-oriented whilst also being ergonomically well thought out. All operating elements are handily placed in front of the driver. Any driver looking at the instrument cluster is greeted by large, easy-to-read instruments. The centrally positioned display offers the driver additional important information. The height and angle of the steering wheel can be pneumatically adjusted.

On the left of the driver's workplace are a series of stowage compartments. On a pedestal, there is a further open compartment as well as the parking brake which is in perfect reach of the driver. If desired, a 50-litre coolbox can be fitted to the right of the dashboard.

Powerful, economical and long-lasting engines

The Intouro is driven by a vertically-installed straight six-cylinder Mercedes-Benz OM 926 LA engine with 7.2 l displacement. It has an output of 210 漀 kW (286 hp) and its maximum torque comes in at 1120 Nm. The low-emissions engine, with its BlueTec diesel technology, meets the EU emissions standards Euro V and EEV. The engine is centrally positioned which ensures easy access to the assembly during maintenance work. Power transmission is effected by the Mercedes-Benz GO 110 mechanical six-speed manual transmission.

As an alternative, the Intouro is also available with the OM 457 hLA engine with 12 l displacement and 220 kW (299 hp) output, in conjunction with a six-speed automatic transmission from ZF.

Active and passive safety

The Intouro is fitted with disc brakes all-round as standard. The rural-service bus is also equipped as standard with the anti-lock braking system (ABS) and optionally with acceleration skid control (ASR). Also available if desired is a retarder.

Annular frame members used in the construction of the Intouro play an important role in its passive safety. This gives the vehicle a high level of torsional rigidity.

The Omniplus service network operates Europe-wide and ensures that your Mercedes-Benz Intouro is always safely on the road.

The Intouro at the International Motor Show for commercial vehicles (IAA) 2012

The lime-green metallic Intouro on show is equipped with the OM 926 LA straight six-cylinder engine with an output of 210 kW (286 hp), a six-speed manual transmission and a retarder. The OM 926 LA complies with the EEV emissions standard. The body is clearly identifiable by its double glazing, LED matrix destination display and a lift at the central entrance. A roof-mounted air-conditioning system keeps the passenger compartment cool. The interior is fitted with 55 Inter Star Eco passenger seats and an interchangeable platform with pram area at the central entrance. Luggage racks are suspended above the seats.

D. Mercedes-Benz Tourismo: the economic wonder is the number one

- Particularly economic model series in the business segment
- Four high-deck touring coaches and two high-floor buses
- Extensive safety equipment including ESP
- Best possible level of protection against corrosion thanks to cathode-dip paint

Presented in 2006 at the IAA, the Mercedes-Benz Tourismo is a true success: more than 5000 units of the touring coach from the business segment have been sold to date. One of the reasons for this success is the clear orientation of the bus as an economic and safe touring coach available in numerous versions.

Four high-deck touring coaches and two high-floor buses

The Mercedes-Benz Tourismo range is made up of four high-deck touring coaches: the two-axle Tourismo (12.1 m long), the two-axle Tourismo M/2 (13 m) and the three-axle versions Tourismo M (13 m) and Tourismo L (14 m). In addition, there is also the high-floor Tourismo RH touring coach with two axles, available in two lengths: 12.1 m and 13 m. This is particularly suited for short tours, day trips and upmarket rural transport (including own account transport).

No-frills body design

The Mercedes-Benz Tourismo comes across as modern and pleasant thanks to its flowing, no-frills body design. Noticeably smooth surfaces on the side walls of the Tourismo ensure that branding and decor can be easily stuck to the vehicle whilst also making the vehicle particularly easy to clean. The beltline drops off towards the front at the height of the first side window. It then opens out energetically to join up with the lower edge of the front windscreen.

Friendly and functional passenger area

Passengers board the Tourismo at the front through a wide entrance. The mid-length version sits 1330 mm (Tourismo) or 1060 mm (Tourismo RH) above the road surface. The passenger compartment has been designed to be both friendly and functional. Once aboard the Tourismo, passengers take a seat in the newest generation of the comfortable and light-weight Travel Star Xtra double seats. Inter Star Eco is the standard seating used on the Tourismo RH. Optionally available are the Travel Star Plus seats, which are suited to touring coaches.

The Mercedes-Benz Tourismo is also suitably equipped to provide perfect climatic comfort aboard. The ideal interior temperature in winter is achieved by the use of warm water convector heating. To keep a cool head in the warmer seasons, the Tourismo is also equipped as standard with an air conditioning system (this is optionally available for the Tourismo RH).

The fittings on board the Tourismo provide individual flare. For example, on the right-hand side of the centre door, a lavatory is optionally available. Numerous types of galley are also available as an optional extra.

Extensive safety equipment including ESP

As with all touring coaches from Mercedes-Benz, the Tourismo has exemplary safety systems fitted as standard, including: the electronically controlled brake system (EBS), disc brakes all-round, anti-lock braking system (ABS), acceleration skid control (ASR), Brake Assist (BA), cruise control, hydrodynamic retarder, Continuous Braking Limiter (DBL) and, above all, the Electronic Stability Program (ESP).

Powerful and economical engines

The drivetrain of the Tourismo ensures optimal economy. At the heart of the drivetrain are in-line six-cylinder engines from the OM 457 series. With their 12-litre displacement and outputs ranging from 260 kW (354 hp) to 315 kW (428 hp), they offer a maximum torque of 2100 Nm. BlueTec diesel technology with SCR technology and AdBlue injection keeps fuel consumption low and respect for the environment high. As standard, the Tourismo meets the low-emissions requirements of the Euro V emissions standard and can optionally be ordered in a version without particulate filter which meets the EEV standards.

Power transmission: six-speed transmission or PowerShift

Power transmission to the rear axle is by means of a six-speed manual transmission with dash-mounted joystick-style gear lever. Thanks to the integrated Servoshift system, gear changes are smooth and precise. The Tourismo can optionally be fitted with an eight-speed Mercedes GO 240-8 PowerShift transmission. This is the first bus-specific transmission in its class and also works towards reducing fuel consumption. Eight gears with progressive gear ratio spreads cover the broad range of requirements, from precision manoeuvring to fuel-saving motorway speeds at low engine speeds.

The chassis of the Tourismo is similar to that of its brother, the Travego – it, too, gets a seal of approval for driving safety and comfort. Like all other buses from Mercedes-Benz, the Tourismo impresses with great manoeuvrability. The 12.1-m-long Tourismo has a turning circle of just 21 m. Taking into account the dimensions of the other variants, they too display impressive handling characteristics. A hydraulically actuated trailing axle with independent suspension helps the three-axle version remain agile.

Best possible level of protection against corrosion thanks to cathode-dip paint

A central element of the vehicle's extensive measures to protect against corrosion is the cathode-dip paint on the Tourismo. The Tourismo's field of operation is a demonstration of just how solid and durable the vehicle really is: among other things, the Tourismo is used on demanding, long-distance lines where a bus can clock up more than 200 000 km in a year.

Portraying economical touring coach travel is a three-star version of the 12.1-m-long, two-axle high-deck Mercedes-Benz Tourismo. The right amount of drive power is guaranteed by an in-line six-cylinder OM 457 hLA engine with an output of 300 kW (408 hp) which complies with the EEV emissions standard. In conjunction with this engine, the show vehicle is equipped with the Mercedes PowerShift GO 240-8 automated transmission. Xenon headlamps underline safety, light-alloy wheels demonstrate elegance, and the FleetBoard on-board computer stands for economy. Equally beneficial to the driver are the reversing camera and the monitoring camera mounted on the centre door.

E. Mercedes-Benz Minibuses: four model series, one route to success

- Sprinter Transfer: rural regular-service bus and excursions
- Sprinter Travel: specialist for tourism and travel
- Sprinter City: low-floor programme for public transport
- Sprinter Mobility: for passengers with restricted mobility

Early 2006 was the beginning of the success story of the latest Mercedes-Benz minibus generation. This generation comprises four model series: the Sprinter Transfer, Sprinter Travel, Sprinter City and Sprinter Mobility with a total of fourteen basic models based on the Mercedes-Benz Sprinter. Mercedes-Benz Minibus GmbH is one of the largest suppliers in its segment in Europe.

Logically structured range

The line-up consists of minibuses in six lengths from 5.9 metres to 8.7 metres and 3.5 tonnes to 6.8 tonnes gross vehicle weight. The Sprinter Transfer is a versatile minibus for regular rural services and excursions. The Sprinter Travel is tailored to excursions and tourism. Sprinter City is the name of the model series with a low-floor design for public transport in urban areas. And finally, the Sprinter Mobility is designed to carry passengers with restricted mobility.

Sprinter Transfer: rural regular-service bus and excursions

The Sprinter Transfer is available in four length variants from 5.9 to 7.6 m and four weight variants between 3.55 and 5.3 t gross vehicle weight. These make up a programme with five basic models. The range reaches from the shortest Sprinter Transfer 23 with twelve passenger seats to the Sprinter Transfer 55 which can seat up to 22 passengers.

The Sprinter Transfer minibus is smartly turned out: it features large parallelogram-shaped flush-mounted side windows and a stylish character line along the flanks to emphasis its dynamic character. The largest model in the rural service series, the Sprinter Transfer 55, has a distinctive bus-type rear as standard with an integrated luggage compartment flap.

Passengers have the choice of embarking via a wide sliding door or through one of the two optionally available outward-swinging doors. An electrically operated step comes as standard. The interior of the Sprinter Transfer is harmoniously attuned to the exterior design.

Passengers in the Sprinter Transfer sit on comfortable seats bearing the name "Inter Star Sprinter". Optionally, the vehicles can be equipped with "Travel Star Sprinter" touring coach seats.

Sprinter Travel: specialist for tourism and travel

The Mercedes-Benz Sprinter Travel minibus range is made up of the models Sprinter Travel 45, 55 and 65, all of which provide outstanding comfort for day trips and long-distance travel.
The touring coach bodies of the Sprinter Travel 45 and 55 are based on the Sprinter panel van.
The Sprinter Travel 55 differs from its smaller brother in that it is 320 mm longer, comes as standard with a touring-coach-style rear end with generous luggage compartment flap and offers up to 1.5 m³ of stowage space. Since the middle of 2011, a luggage compartment well combined with a rear platform has been part of the equipment package for the Sprinter Travel 45. Access to the roughly 1.25 m³ large luggage compartment is via the Sprinter's rear doors. 

The Sprinter Travel 65 is distinctive thanks to the frame-like structure of its independent body. A typical feature is its particularly elegant appearance with large, generous windows including a panoramic windscreen which extends up above the front of the vehicle. The flagship of the series also stands out thanks to the special touring-coach-style rear end with luggage compartment door and 2.0 m³ of luggage space, a large rear window and an interior width which is around 10 cm larger.

The Sprinter Travel is instantly recognisable by its chrome radiator grill. All the models offer an exclusively styled passenger compartment, from seats with reclining backrests to the air-conditioning system. The Sprinter Travel 65 pampers its passengers as standard with Travel Star Xtra luxury touring coach seats, double glazing, an air sprung rear axle and much more.

Sprinter City: low-floor programme for public transport

The Sprinter City series with its low-floor construction is the specialist for regular service buses in urban areas. Whereas the Sprinter City 35 (6.9 m long, up to 22 passenger seats) is based on a modified panel van, the larger Sprinter City 65 (7.7 m long, maximum 30 passenger seats) is instantly recognisable by its independent body and ample glazing. The elegant panoramic windscreen cuts right back into the vehicle roof, thus also providing enough space for an integrated destination display.

The Sprinter City range is rounded off by the new Sprinter City 77. Its low-floor frame with a tandem rear axle is an exclusive development, as is the body. The Sprinter City 77 provides 40 passenger seats, an all-through low floor in the passenger compartment and space for a second wheelchair. The chassis of the three-axle vehicle boasts independent suspension all round and single tyres.

Sprinter Mobility: for passengers with restricted mobility

The Sprinter Mobility is carefully designed to meet the needs of passengers with restricted mobility. There are two models: the Mobility 23 (5.9 m long) and the larger Mobility 33 (6.9 m long). Both are based on the Mercedes-Benz Sprinter as a panel van with high roof and double rear doors. They both have a gross vehicle weight of 3.5 t.

Seven or eight passenger seats are standard. Numerous other seating variants are available on request. The passenger compartment floor is fitted with an integrated rail-type mounting system to enable flexible seating configurations as well as the transport of wheelchairs.

If desired, the Mercedes-Benz Sprinter Mobility can be modified to suit a variety of needs. Versions are available with electrically retractable steps for both the front-passenger door and the sliding door. A linear platform lift or a swivel lift is also available for the rear of the vehicle. A third underfloor variant of the lift is particularly space-saving in the vehicle interior.

The ideal basis: the Mercedes-Benz Sprinter

The minibuses are all based on the Mercedes-Benz Sprinter range of vans. They are driven by powerful, efficient diesel engines with outputs ranging from 70 kW (95 hp) to 140 kW (190 hp). All the engines comply with the Euro V or optionally even the EEV (Enhanced Environmentally friendly Vehicle) emissions standards. The engines are equipped with a diesel particulate filter as standard.

The ECO Gear six-speed manual transmission handles the transfer of power. An automatic transmission is standard on the Sprinter City 35, Sprinter City 65 and Sprinter City 77. The automatic transmission is an optional extra for the other minibus models.

The new 7G-TRONIC automatic transmission is gradually being integrated into the programme. The advantage of the new seven-speed transmission is the combination of a wide overall spread and short gear ratio steps from one gear to the next. In practice this means: a short transmission ratio for first gear ensures a dynamic start. At higher speeds, the Sprinter runs economically with low emissions and low noise levels, all at low engine speeds.

The minibuses based on the Mercedes-Benz Sprinter are among the safest in their class. The highlight is ADAPTIVE ESP, fitted as standard. Handling and driving comfort are similar to those of a passenger car. Air suspension on the rear axle is available as an extra for the Sprinter Transfer/Travel 45 and 55 minibus models and is even standard for the Sprinter City 65, Sprinter City 77 and Sprinter Travel 65.

The pinnacle of minibuses is portrayed by a Sprinter Travel 65 with anthracite metallic matt paint. It has a six-cylinder CDI engine with 140 kW (190 hp) output and automatic transmission. Safety is enhanced by xenon headlamps and a retarder. This exclusive minibus is kept at a pleasant temperature by air conditioning for the driver's and passenger areas, convector heating, a hot-water auxiliary heater and an electric hot-air heater. For the passengers, there are fifteen Travel Star Xtra seats with Luxline upholstery and leather headrests.
