Mercedes-Benz Tourismo: a new star among the touring coaches

The most successful European high-deck touring coach of recent years is making way for its successor. After more than 12,000 Mercedes-Benz Tourismos of the outgoing generation, now an entirely redesigned and newly developed Tourismo has arrived, one that has only its name in common with its predecessor. The coach stands out by virtue of its perfect balance of outstanding economy, comfort and safety and is making its world premiere at the IAA Commercial Vehicle Show 2006.

The new Mercedes-Benz Tourismo covers a range of segments. It is the successor to the previous Tourismo and at the same time, thanks to its versatility, the replacement for the previous models Integro H and Travego RH. As an economical all-round coach, it is suitable for a broad spectrum of applications in the wide-ranging segment covering touring, transfers and excursions. It sets a new standard for safety in its class, offers a modern design typical of its brand and, most of all, provides the proven quality of Mercedes-Benz.

Range of four high-deck touring coaches including a 13-metre-long, two-axle coach

The Mercedes-Benz Tourismo production series consists of four high-deck touring coaches: the two-axle Tourismo (length 12.1 metres); the Tourismo M/2 (13 metres), also with two axles, and the three-axle Tourismo M (13 metres) and Tourismo L (14 metres). All of the models have a height of 3620 mm. With this coach series, Mercedes-Benz seamlessly covers the business segment for functional high-deck touring coaches. In terms of economical operation, both the 12.1-metre-long Tourismo and, in particular, the weight-optimised Tourismo M/2 are of interest. Thanks to its longer wheelbase, the two-axle 13-metre coach offers one row of seats more than usual in a coach of its size — and that means three-star seating for 53 passengers.

Unpretentiously designed body from the Mercedes-Benz family of buses

With its flowing and unpretentious design, the body of the new Tourismo has a modern and pleasing look. Its membership of the Mercedes-Benz family of buses and coaches is unmistakeably apparent from the first glimpse of its front end. The side walls of the vehicle have a remarkably smooth surface. The coach’s belt line runs diagonally down and forward at the level of the first side window, merging smoothly into the lower edge of the windscreen. The Tourismo’s character line also takes up the same gesture at a higher level, lending the silhouette of the Tourismo an almost filigree appearance.

With its high-reaching V-shaped rear window, the three-dimensional design of the rear lights, and the engine flap with its trapezoidal air intake, the rear of the touring coach displays the design vocabulary it shares with other buses and coaches from Mercedes-Benz.

Friendly and functionally designed passenger compartment

The design of the passenger compartment is as friendly as it is functional. With a standing room height of 2010 mm in the centre aisle, it is sufficient for even tall passengers. The external width of 2550 mm means that the interior offers lots of freedom of movement for the passengers. The passengers sit in comfort on “Travel-Star Plus” model seats, which feature very comfortable upholstery and a pleasant degree of lateral support. Above the passengers, the new, harmonious and attractively designed service sets are integrated flush with the surface of the air ducts in the roof. Cosy temperatures in winter are provided by the hot-water convector heater. For keeping a cool head in the hotter seasons, the air conditioning system fitted as standard in all Tourismo variants provides 32 kW or 35 kW of cooling power. Two roof lights are also fitted to facilitate interior ventilation.

Individuality is the hallmark of the new Tourismo. An on-board toilet can be optionally fitted to the right of the central entrance. The galley, which is also optional, is available in a number of variants. An audio system with DVD player and two 15-inch flat-screen monitors perfectly complement the new touring coach’s standard-equipment on-board entertainment system. If the bus is fitted with an on-board toilet, the volume of the luggage compartment in the new Tourismo is 8.4 cubic metres, and 11.0 cubic metres in the case of the Tourismo L. Hinged flaps are fitted as standard, but luggage compartment flaps with a lifting mechanism for opening can be fitted as an option.

Driver-oriented cockpit with joystick gearshift

Although the driver-orientated cockpit has been redesigned and ergonomically optimised in line with the latest research findings, it displays the characteristic elements that make it undeniably a Mercedes-brand touring coach. To the right of the driver is a joystick lever on the instrument panel. To the left of his or her seat, the driver will find an open tray and a cup holder located on top of a console, where the parking brake lever is now also within easy reach. Another new feature of the Tourismo is the Opticool windscreen, which is already found in other buses and coaches from Mercedes-Benz. This windscreen substantially reduces the amount of heat and infrared radiation entering the vehicle.

Comprehensive safety equipment including ESP

Like all of the brand’s other new Mercedes-Benz touring coaches, the Tourismo is equipped with an exemplary range of safety features as standard: the Electronic Braking System EBS, disc brakes all round, the anti-lock braking system ABS, acceleration skid control ASR, Brake Assist BAS, cruise control, hydrodynamic retarder, continuous brake force limiter DBL and, above all, the Electronic Stability Programme ESP.

Powerful yet thrifty Euro 4 engines with BlueTec diesel technology

All models of the new Tourismo are equipped with the Euro 4-compliant OM 457 LA six-cylinder in-line turbodiesel engine, which has 12 litres of displacement. The two-axle variants are fitted with horizontal engines (OM 457 hLA) with power outputs of 260 kW (354 hp) or 300 kW (408 hp). The engines have maximum torques of 1600 Nm and 1900 Nm respectively. The three-axle vehicles feature vertically mounted engines (OM 457 LA) with 315 kW (428 hp) and 2100 Nm of torque. Depending on the individual Tourismo, the engine power is transmitted to the wheels by Mercedes-Benz GO 190 or GO 210 six-speed manual transmissions. The new engines feature BlueTec diesel technology with a downstream SCR catalytic converter to satisfy the EU’s Euro 4 exhaust emissions standard. This technology not only ensures clean exhaust, but also very low fuel consumption. The Tourismo’s low operating costs are also due to the long maintenance intervals of 90,000 km.

The Mercedes-Benz Tourismo at the IAA Commercial Vehicle Show 2006

The new Tourismo will be in the spotlight at the IAA Commercial Vehicle Show 2006, where it will be celebrating its world premiere. The vehicle on display will be a 12.1-metre-long two-axle version with a three-star interior and the OM 457 hLA engine generating 300 kW (408 hp). The “Travel-Star Plus” passenger seating has three-star spacing, and the seats are fitted with leather piping and leather headrests. A DVD system rounds out the standard equipment entertainment electronics.

Mercedes-Benz Travego new high-deck touring coach: available in three different lengths

In terms of safety and comfort, and by virtue of its appointments, attractive appearance, and very environmentally friendly new, fuel-efficient Euro 4 engines, the Travego sets new standards for high-quality touring coaches. The new Mercedes-Benz Travego line-up comprises the high-deck touring coaches Travego (12.14 metres long, two axles), Travego M (12.96 metres long, three axles), and the Travego L (13.99 metres long, three axles).

Shape and design further enhanced and more dynamic

The new Mercedes-Benz Travego has further enhanced the exterior lines of its predecessor. By way of example, the “face” of the coach now has much more dynamic and clearly defined features. The three-dimensional profile of the B-column’s character line emerges more forcefully than ever before out of the vehicle’s body. At the bottom it makes a sweeping arch that extends into the front door. The B-column elegantly rises to the roof, where it merges smoothly with the housing of the roof-mounted air-conditioning unit.

The new Travego’s front section was lengthened by 140 mm. This creates more room for the driver and tour guide and makes it possible to substantially expand the width of the entrance. The rear of the Travego has also been enhanced. Particularly eye catching are the three-dimensional tail lights stretched around the sides and featuring passive lighting elements. The engine cover and rear panel bulge more strongly on the sides, as do the corners of the bumpers. The overall appearance of the Travego is harmoniously shaped in the dynamic manner typical of the brand.

Exemplary Safety Coach appointments, including continuous brake-force limiter (DBL), proximity control (ART) and Lane Assistant (SPA)

The safety level of the new Mercedes-Benz Travego’s predecessor was already exemplary, featuring the electronic braking system (EBS), Brake Assist (BA), acceleration skid control (ASR), retarders and, most importantly, the Electronic Stability Programme (ESP). In the new Travego, this standard range of equipment has been augmented by the continuous brake-force limiter (DBL), which prevents the coach from unintentionally accelerating above the speed limit when driving down an incline.

Available for the first time in the new Travego is the optional proximity control system (ART) which automatically maintains a pre-selected safety distance to vehicles travelling up ahead. Another new feature is the Lane Assistant (SPA), which is equipped with a camera system that tracks the lane’s boundary markings in order to recognise if the coach is about to leave its lane. Should this be the case, the system immediately warns the driver.

Many passenger compartment details upgraded

In the new Travego’s interior, passengers will appreciate the redesigned service sets underneath the air ducts. Another innovation is the interior lighting concept consisting of fluorescent tubes and discreet ambient lighting for the floor along the centre aisle. The roof dome above the driver and tour guide was completely redesigned. The new design was made possible through the installation of flat-screen monitors for the standard-fitted DVD player. Depending on the vehicle’s type and application, coach operators can now choose between air conditioners with output ratings of 32 kW, 35 kW or 39 kW. The hot-water convector heater has been retained from the predecessor. Alternatively, a propeller fan heater can be ordered for the coach as an option.

New base engine: 315 kW (428 hp) and more torque

The Travego’s new base engine is the OM 457 LA with an output of 315 kW (428 hp). However, even more important than the increase in the engine’s rated output is the jump in its pulling power. As a result, the in-line six-cylinder’s peak torque has risen from 1900 Nm to 2100 Nm. No change has been made to the performance of the most powerful engine for the Travego, the eight-cylinder OM 502 LA V-engine with 15.9 litres of displacement and an output of 350 kW (476 hp). This engine also has a peak torque of 2100 Nm.

Fuel savings are among the reasons that speak in favour of using Euro 4-compliant engines with BlueTec diesel technology in touring coaches. Compared to Euro 3 vehicles, these savings can amount up to 6 %. This reduction has to be balanced against the amount of AdBlue required. In the new touring coach, only about 3 % to 5 % as much AdBlue is consumed as diesel. The coach’s profitability was also enhanced by increasing the maintenance intervals from 60,000 km to 90,000 km. BlueTec is very simple to handle: on the right-hand side of the vehicle and right next to the filler neck of the fuel tank or in its immediate vicinity is a flap for a second filler neck for AdBlue. Depending on the model in question, the AdBlue tank has a volume of 61 litres (Travego) or 47.5 litres (Travego M and Travego L), which suffices for travelling many thousands of kilometres.

Servoshift makes gearshifting easier and more precise

The engine power is now transmitted as standard by the Mercedes-Benz GO 210 six-speed manual transmission. As in the previous Travego, this transmission is operated by means of a joystick in the dashboard. An enhanced Servoshift makes gearshifting even easier and more precise than was previously the case. The Travego can instead be equipped with the optional AS-Tronic automated manual transmission from ZF, which has twelve gears. The Mercedes-Benz Bus and Coach unit manufactures the new Travego variants Travego 15 SHD and Travego 17 SHD especially for the Turkish market. These two super-high-deck touring coaches are 12 metres and 13.85 metres long, respectively. They are both 3.97 metres high and are powered by the Euro 3-compliant engines of the previous model, in accordance with the needs of the Turkish market.

The Mercedes-Benz Travego at the IAA Commercial Vehicle Show 2006

The Travego M exhibited at the IAA Commercial Vehicle Show 2006 is the flagship model of the product line-up and comes with an extensive range of safety features, including proximity control (ART) and Lane Assistant (SPA). The comfort-enhancing appointments include Travel-Star Xtra seats with leather appliqués, a second refrigerator, a panorama camera, and a navigation system that is hooked up to the monitors. The drive train comprises an OM 457 LA turbodiesel (315 kW/ 428 hp) that satisfies the Euro 4 emissions standard, in tandem with a GO 210 six-speed manual transmission.

Mercedes-Benz Tourino: upgraded midicoach

As a full-line supplier, the Mercedes-Benz Bus and Coach unit fulfils all customer wishes. One example of this is the Mercedes-Benz Tourino midi touring coach, which is 9.35 metres long and can seat up to 36 passengers. Besides state-of-the-art technology, it also comes with a comprehensive range of appointments. No other midicoach can boast the combination of rear-mounted engine, independent front suspension, and a high-quality comprehensive safety package that includes ESP.

New: compact onboard galley, increased payload, optimised cockpit

A new seating variant for the four-star standard has seven rows of seating on the left and right of the coach, and also includes a kitchen in the rear of the vehicle. Alternatively, the Tourino can also be equipped with a compact galley at the rear entrance without sacrificing seating space. The vehicle’s new cockpit now corresponds to that of the large buses that bear the Mercedes star. The driver also benefits from the substantially increased aperture angle of the pivotable luggage compartment flaps. The reused Mercedes-Benz HO4 rear axle with a gross axle weight rating of 9.44 tonnes allows the gross vehicle weight rating to be increased by about half a tonne to 13.15 tonnes. This significantly raises the payload reserve.

Euro 4 engines with BlueTec diesel technology are more powerful and economical, and cleaner

The Tourino midi touring coach is powered by a rear mounted OM 926 LA turbo-diesel engine. However, the drive system now uses BlueTec diesel technology with an SCR catalytic converter, thereby enabling the coach to meet the Euro 4 emission limits. This adjustment has been accompanied by a noticeable increase in engine power, with output rising to 210 kW (286 hp) and torque to 1120 Nm. The engines equipped with BlueTec technology stand out not only through their cleaner emissions, but also through noticeably lower fuel consumption.

The Mercedes-Benz Integro: rural bus with touring-coach roots

The Mercedes-Benz Integro is uncompromisingly tailored for rural traffic. With three length variants of 12.14 m (Integro), 12.98 m (Integro M) and14.92 m (Integro L), it covers the entire range of rural applications and is equally well suited as a money-maker for shuttle trips or excursions.

Clear and distinctive styling evident of kinship with the touring coach

The three-dimensional styling of the Integro’s front moulding closely resembles the new design of the Travego coach’s front. The Integro’s basic shape is determined by functional considerations in accord with its purpose. The steep windscreen is big enough to accommodate a large destination display and to allow optimum use of the available space. The stylistic elements at the rear further underscore the fact the vehicle is a member of the Mercedes-Benz family of buses. The front section of the two-axle variants has been extended by 140 mm for the benefit of the driver and passengers. At the forward end the Integro sports a single-wing, hinged door that opens outward. The 1380-mm-wide door in the middle has two wings as standard, although a single-wing is available as an option.

Like the centre aisle, the Integro’s driver space is located 860 mm above the road surface. The cockpit has a driver-orientated design. The lever of the gearshift joystick is positioned ideally within reach of the driver’s hand. A fully equipped cab is available as an option. If the new Integro is also intended for excursions, a chest refrigerator can be installed up front in the right side of the instrument panel. Alternatively, the cab can be ordered with a stowage cabinet.

Spacious passenger compartment with innovative rural bus seats

An appealing feature of the Mercedes-Benz Integro is the floor-to-ceiling height of 2.19 m. The pleasant sense of roominess is also enhanced by the exterior width of 2.55 m, providing more interior space. Passengers will be pleased by the stylish and functional design of the ceiling and the full-length luggage racks with the perforated aluminium bottom. Designed especially for the new rural bus, the Inter-Star Eco seats are available with backrests of different heights. These seats appeal not only because of their comfortable upholstery, but also because of their styling with slender headrests. The seat support along the aisle is reminiscent of the bent steel legs of modern office chairs. The Integro is furthermore available optionally with the superbly comfortable Inter-Star Plus or Travel-Star Eco seating systems, which provide the comfort of a touring coach. Other options include a pram space or a removable platform opposite the middle door. Options also include ventilation nozzles as well as reading lights.

Powerful yet thrifty Euro 4 engines with BlueTec diesel technology

The Integro is powered by economical high-performance turbodiesel engines, compliant with the Euro 4 emissions standard and fitted with BlueTec diesel technology. All models of the Integro come equipped with the horizontal in-line six-cylinder Mercedes-Benz OM 457 hLA engine with twelve litres displacement. The engine comes standard with a power output of 220 kW (299 hp). An optional version delivers 260 kW of power (354 hp). This is the standard engine in the Integro L, which is optionally available with a more powerful engine variant delivering 300 kW (408 hp). The engine power is transmitted by a manually operated, mechanical, six-speed Mercedes-Benz transmission, with joy-stick operation and Servoshift support. Shifting gears will become even more convenient when the automated EPS 3 six-speed manual transmissions become optionally available early in 2007. In these transmissions the gear-shifting and clutching operations are performed electropneumatically. Optionally, the vehicle can also be fitted with fully automatic converter transmissions from ZF and Voith.

Disc brakes all round, ESP as an option

Safety is a top priority in the Integro. Disc brakes are used all round. An anti-lock braking system (ABS) as well as acceleration skid control (ASR) are standard equipment in the new rural bus. The two-axle versions of the new Integro equipped with the manually operated six-speed manual transmission or the automated EPS 3 manual transmission are optionally available with the Electronic Stability Programme (ESP), as well as the electronic braking system (EBS), which includes Brake Assist (BA).

A chassis that ensures safety — and a comfortable ride like in a touring coach

A prerequisite for the safe handling as well as comfortable ride of the new Integro is a chassis replete with touring coach technology. The front axle for instance features the independent suspension from the new Travego. This suspension can achieve wide steer angles (up to 58 degrees for the inner wheel in a turn) that provide extraordinary manoeuvrability. The drive axle is a Mercedes-Benz HO6 hypoid axle. The trailing axle in the Integro L is the ZF unit RL 75 A with electrohydraulic rear axle steering (RAS). Because of a number of weight-reducing design features, the Mercedes-Benz Integro now weighs about 170 kg less than its predecessor. Operating costs are consistently minimised by the lower fuel consumption and the longer maintenance intervals of up to 60,000 km (motor oil changes).

The Mercedes-Benz Integro at IAA Commercial Vehicle Show 2006

The versatility of the Mercedes-Benz Integro is underscored by the show bus, a 13-metre-long Integro M. A removable pram platform at door 2, wheelchair immobiliser, Inter-Star Eco seating, and chest refrigerator underscore the Integro’s compatibility with both regular service and excursions. Both of these applications are well supported by a drive train comprised of the horizontal OM 457 hLA Euro 4 turbodiesel engine with a power output of 260 kW (354 hp) and the Mercedes-Benz EPS 3 automated six-speed manual transmission.

Mercedes-Benz Citaro: new generation, new compact low-floor bus Citaro K

The Mercedes-Benz Citaro is already one of the best-selling regular-service buses bearing the Mercedes star. With nearly 15,000 models sold since series production began in 1998, it can be seen on the streets of almost all of Europe’s major cities. Now, the second generation is on the way: the Citaro has been revamped technically and visually in a number of respects. At the same time, the new Mercedes-Benz Citaro K is rounding out the Citaro range of regular-service urban and rural buses. The “shortened” urban bus is celebrating its public debut in a genuine world premiere at the IAA Commercial Vehicle Show 2006.

Mercedes-Benz Citaro: unique range of low-floor regular-service buses

The new Citaro K, a compact variant 10.5 metres in length, is now extending the already broad range of the Mercedes-Benz Citaro. That means the range of the low-floor regular-service Citaro now consists of 11 variants with a large number of different lengths that fully cover all the transportation needs of bus operators in urban and rural transport. The product range consists of urban buses measuring from 10.5 metres to 18 metres in length, rural buses measuring between 12 metres and 18 metres, and low-entry urban and rural buses measuring between 12 metres and 13 metres.

Mercedes-Benz Citaro K: compact and highly manoeuvrable

The new Citaro K was developed from the versatile modular construction kit of the Citaro range: it is based on the 12-metre-long Citaro, whose wheelbase was shortened to 4398 mm. The result is a compact, 10.5-metre-long, two-door low-floor urban bus with two axles, a vehicle ideal for routes with low numbers of passengers. Because gross vehicle weight has remained unchanged at 18 tonnes, the Citaro K can carry up to 91 passengers, depending on the seating. Because it has a turning circle of only 17.2 metres, the new Mercedes-Benz Citaro K is easy to manoeuvre and perfectly suited for use in winding inner-city streets.

The new Mercedes-Benz Citaro K is powered by a horizontally-mounted Mercedes-Benz OM 906 hLA in-line turbodiesel with six cylinders and an output of 210 kW (286 hp). The engine is equipped with BlueTec diesel technology, and is available in either Euro 4- or Euro 5-compliant versions. The drive systems and automatic transmissions from ZF and Voith as well as other components were taken directly from the Citaro urban buses. This is true as well of the many changes with which the second generation of the Citaro is now being launched.

A regular-service bus with a “face”

One of the first things that catches the eye is the “face” of the second-generation Citaro. New features include a curved recess between the headlamps which gives the impression of a radiator grille. With their clear-glass covers, the rotated indicator housings contribute to the vehicle’s friendly appearance. At the front end, screw fixings are not visible in the new Citaro regular-service buses. In addition to the front-end cover, the corner panels, including the headlamp housings, can be folded forward as well — so the whole front end is perfectly accessible for maintenance work.

The rear of the Citaro is now fleshed out more in three dimensions. The V-shaped rear window extends upward and reaches into the roof. The engine cover ends at the top in a ventilation opening, sealed by a black mesh plate. The whole design vocabulary of the Citaro, including the new tail lights, evokes the new generation of coaches and rural buses from Mercedes-Benz.

Refined interior and driver area

The passenger compartment is characterised by new ceiling panels, strip lighting and the new, light-weight urban bus seating system City-Star Eco, which features comfortably enlarged dimensions (+ 24 mm) but the same seat divider. Also new in the Citaro is the Opticool windscreen, which acts as an excellent thermal insulator and absorbs infrared radiation, thereby increasing driver comfort. The driver area is equipped with new stowage trays and can be augmented by an optional electrically cooled bottle rack.

Economical and clean Euro 4 and Euro 5 engines, certifiable according to EEV

All of the standard engines for the Citaro models are Euro 4 powerplants using BlueTec diesel technology. The very compact and lightweight OM 906 hLA six-cylinder in-line engine has a displacement of 6.4 litres and an output of 210 kW (286 hp). Optionally, the vehicle can be equipped with the Euro 4-compliant OM 457 hLA six-cylinder in-line turbodiesel with a displacement of 12 litres and two output ratings (220 kW/299 hp and 260 kW/354 hp). The Mercedes-Benz Citaro can also be delivered with the optional OM 906 (h)LA diesel engine that already satisfies the EU emissions standard Euro 5, which will go into effect in 2008/2009. Another optional Euro 5-compliant engine, the OM 457 (h)LA, will be available from spring 2007. At the same time, there will be OM 906 hLA and OM 457 hLA engines that comply with the even more stringent EEV (Enhanced Environmentally-friendly Vehicle) emissions standards — further proof of the great potential and the future viability of BlueTec diesel technology.

As in the previous Citaro model, the engine power is transmitted by an automatic converter transmission, available from either ZF or Voith. For the rural bus variant of the Citaro LE, the six-speed manual transmission Mercedes-Benz GO 190 will be available in connection with the new automated gearshift EPS 3 beginning in early 2007.

Front independent suspension improves comfort and handling

Another new feature in the Citaro is the front axle with independent suspension. Its benefits include impressive straight-line stability, less road impact on the steering, a substantial weight reduction, lower unsprung masses and a general improvement in handling and ride comfort. The front axle has a very large steering angle (inside 53 degrees, outside 46 degrees), without any restriction of the aisle width. As a result, the turning circle of the 12-metre Citaro variant has been reduced by half a metre to just 21 metres.

And, thanks to the increased spring travel and air spring volume of the suspension bellows, ride comfort is enhanced for driver and passengers alike. In the articulated bus variants of the Citaro, handling have recently been improved even further by an optional roll/pitch control with damper characteristics that are controlled electronically in accordance with the driving situation and the load.

The Mercedes-Benz Citaro regular-service buses at the IAA Commercial Vehicle Show 2006

Two Citaros are being exhibited at the IAA Commercial Vehicle Show 2006 in Hanover. On display is a new Mercedes-Benz Citaro K equipped with an infotainment system with two monitors, the City-Star Eco seating, the new Euro 5-compatible OM 906 hLA turbodiesel, and an automatic transmission from Voith. The second exhibit is a low-entry Mercedes-Benz Citaro LE Ü rural bus featuring a drive train consisting of an OM 457 hLA six-cylinder in-line engine with 220 kW (299 hp) of output, and an automatic transmission from ZF. The passenger area of the Citaro LE Ü is equipped with the new Inter-Star Eco rural bus seats.

Mercedes-Benz CapaCity: series production of high-capacity bus to commence in 2007

The Mercedes-Benz CapaCity low-floor, high-capacity bus, which was presented as a prototype in late 2005, is now ready to go into series production. Measuring 19.54 metres in length, the CapaCity has a four-axle, four-door articulated bus concept (with only one articulated joint) that opens up a new chapter in the development of high-capacity urban buses.

The new vehicle from Mercedes-Benz is a perfect example of the attractiveness and economy buses offer as a mode of transport. Although it’s a non-rail, high-capacity vehicle, it nevertheless combines the typical benefits of a bus (great flexibility and economy) with tram-like virtues such as the capability of transporting a large number of passengers. As such, the CapaCity represents an ideal element of an innovative transport system, and a welcome supplement to existing tram networks. This summer, the Mercedes-Benz CapaCity was presented to customers in four large German cities, where the vehicle was tried out on regular routes. All of the transport companies were particularly impressed not only by the CapaCity’s design, technology and readiness for series production, but also by its agility and manoeuvrability, which are comparable to those of a normal-size articulated bus.

Capacity for up to 193 passengers, low operating costs

The CapaCity’s length of 19.54 metres and its fourth axle have led to an increase in its gross vehicle weight to 32 tonnes — and thus a significantly higher passenger transport capacity. Assuming maximum permitted use of standing room of eight people per square metre, the three tonnes of additional payload enables transport capacity to be increased by up to 40 percent to a maximum of 193 passengers, depending on the seating arrangement used in the bus. The vehicle’s four double-width doors (two of which are located in the trailing section), completely step-free entrances and exits, and large areas for standing passengers all ensure rapid passenger entry and exiting.

A characteristic feature of the CapaCity is its harmonious design. The design of its friendly “face” accentuates the three-dimensional front panel, at the centre of which is the Mercedes star on its own base. The side windows appear larger due to black-painted areas that extend far down. The roof also has a harmonious design that conceals the roof-mounted units under coverings and emphasises the vehicle’s dynamic appearance.

Manoeuvrability and safety of a normal-size articulated bus

Despite being 19.54 metres in length, the Mercedes-Benz CapaCity negotiates its way through traffic just as easily as a conventional articulated bus, thanks to its four axles (two of which are steered) and a single articulation joint. Its 22.85-metre turning circle is exactly the same as that of the 17.94-metre Citaro G three-axle articulated bus, which means the new CapaCity is just as easy to manoeuvre in curves as the tried-and-tested Citaro G. The width of the slewing ring is also the same for both buses. At 0.42 metres, the rear swing-out value in the 25 metre circle is significantly lower than the maximum permitted value of 0.60 metre. As a result, the CapaCity is much more agile than other high-capacity bus concepts. Because the CapaCity has only one articulated joint, it can drive in reverse as easily as any conventional articulated bus. Drivers can always see the rear and the doors.

Higher handling stability thanks to four axles and roll/pitch control

The CapaCity’s high level of manoeuvrability is thanks to an electrohydraulically steered trailing axle. The vehicle’s four axles ensure even higher handling stability when in forward motion. The chassis, which has independent suspension for the front axle and a roll/pitch control with variable shock-absorber response and electronic control, is both safe and comfortable.

Powerful and efficient Euro 4 engines

The rear of the CapaCity houses the proven horizontal six-cylinder in-line Mercedes-Benz OM 457 hLA engine with 12 litres displacement. This efficient and clean Euro 4 turbodiesel unit with SCR BlueTec diesel technology drives the third axle. Engine output of 260 kW (354 hp) gives the CapaCity driving performance and traction values far superior to competing concepts, despite its higher weight. The Mercedes-Benz CapaCity will also profit in the future from the availability of new engines certified according to the Euro 5 and EEV standards.

Exemption from maximum bus-length rule in Germany

At 19.54 metres, the length of the CapaCity exceeds the current permissible maximum of 18.75 metres in Germany, which is why a special exemption is required to operate it on public roads in the country. In April 2006, the German Ministry of Transport issued such a general exemption, which will enable the Mercedes-Benz CapaCity to be operated anywhere in Germany without restrictions. Series production of the Mercedes-Benz CapaCity will commence in 2007.

The Mercedes-Benz CapaCity at the IAA Commercial Vehicle Show 2006

The high-capacity Mercedes-Benz CapaCity bus will be presented in its series-production version on the outside grounds immediately in front of Halls 14/15.

Mercedes-Benz OC 500: bus chassis offer a proven foundation to body manufacturers worldwide

Customised bus bodies for special applications, or for meeting legal requirements and preferences in a specific country, are best mounted onto proven bus chassis by local manufacturers. With its OC 500 series, Mercedes-Benz offers a broad range of chassis and engine variants.

Wide range of chassis for all applications

The OC 500 series from the Sámano plant in Spain includes chassis for rural buses and touring coaches (OC 500 RF) with two and three axles, and a low-entry chassis (OC 500 LE). As is the case with the complete buses, the chassis are fitted with horizontally mounted Euro 4 engines featuring BlueTec diesel technology that is based on the SCR system. The OM 457 (h)LA six-cylinder in-line engines with 12 litre displacement are available in output ratings ranging from 220 kW (299 hp) to 315 kW (428 hp). A natural gas engine is also available for the OC 500 LE chassis.

The OC 500 RF (RF = raised floor) chassis stands out through the use of state-of-the-art technology. Its standard features include CAN data bus, the electronic braking system (EBS) with ABS, disc brakes all round, front independent suspension, air suspension, a six-speed manual transmission with joystick gearshift, and interfaces to the electrical/electronic system in the body.

New: optimised weight and Euro 4 engines equipped with BlueTec diesel technology

The Mercedes-Benz Bus and Coach unit will present a “redesigned” variant of the two-axle OC 500 RF chassis at the IAA Commercial Vehicle Show 2006. Along with the OM 457 hLA low-emission and economical Euro 4 turbodiesel engine, the chassis also weighs about 150 kg less than its predecessor. This extra weight can be used for the body and payload.

Mercedes-Benz Buses and coaches: Euro 4, Euro 5 and EEV

All new large buses from Mercedes-Benz (EvoBus GmbH) will be equipped with BlueTec diesel technology. The complete range of urban and rural buses and touring coaches will thus be available with the pioneering technology to coincide with the launch of the Euro 4 emission standard. BlueTec effectively combats environmental pollution and also noticeably reduces fuel consumption.

BlueTec diesel technology with efficient filtering

The first Mercedes-Benz Citaro urban buses underwent practical testing with new BlueTec diesel technology around one year ago: since then, they have impressively demonstrated their effectiveness in everyday operations. The OM 906 hLA or OM 457 hLA turbodiesel engines used in the test by the buses (both Euro 4-compliant) consumed approximately 6 % less fuel on average than Euro 3 engines. Series production of Citaro urban buses with Euro 4 engines has been under way for quite some time — and deliveries of the first buses equipped with Euro 5 engines (also with BlueTec diesel technology) began two months ago. BlueTec diesel technology from DaimlerChrysler is based on a combination of enhanced engine technology and an exhaust-gas treatment process. The highly efficient combustion within the engine generates extremely low emissions that are almost as clean as filtered exhaust when it comes to particulates. The nitrogen oxides are then converted to harmless nitrogen and water vapour with the help of an integrated after-treatment system based on the SCR principle, which involves the addition of the AdBlue aqueous reducing solution in a catalytic converter.

The vehicle’s engine electronics control the addition of the appropriate amount of AdBlue from a separate tank into the high-temperature engine exhaust, where it is converted into ammonia. This, in turn, initiates the desired chemical reaction. BlueTec technology is geared to the future, as it can also meet the Euro 5 standard (which will come into effect in 2008/2009), without any need for additional treatment or filter systems. What’s more, BlueTec also meets the even more stringent EEV (Enhanced Environmentally-Friendly Vehicle) emissions standard.

Secure supply of AdBlue

The AdBlue infrastructure at public filling stations has already reached an advanced stage of development (see the website at www.findadblue.com). Company fuelling facilities and special AdBlue stations can also be established without any problems. Vehicles fill up with AdBlue via a second filler neck located right next to the primary fuel tank filler neck. AdBlue consumption in conjunction with Euro 4 engines equipped with BlueTec diesel technology amounts to roughly 2–4 % of diesel fuel consumption. In the Euro 5 variant it amounts to about 5.5 %. As a result, a full tank of AdBlue will generally last as long as at least two to three tanks of diesel.

BlueTec plus particulate filter equals compliance with the EEV emissions standard

BlueTec diesel technology’s ability to meet the demands of the future will be demonstrated at IAA Commercial Vehicle Show 2006 by an OM 906 hLA turbodiesel engine that meets the EEV (Enhanced Environmentally-Friendly Vehicle) emissions standard. This voluntary standard, which is even more stringent than Euro 5 (valid from 2008/2009), can currently only be met by natural gas-powered engines. Mercedes-Benz will begin delivering EEV-compliant Citaro urban buses to those customers who request them in the second quarter of 2007.

The exhaust gas limit will be met through the combination of the OM 906 hLA BlueTec diesel engine and a particulate filter. The sintered metal filter is manufactured by Purem, which is a DaimlerChrysler subsidiary. The particulate filter and the SCR catalytic converter for the BlueTec diesel technology are contained in the same housing, as will be demonstrated by the EEV engine displayed at the IAA Commercial Vehicle Show 2006. The Citaro will also be available as an EEV-compliant model with the larger OM 457 hLA engine next year.

Mercedes-Benz minibuses: premiere for the Sprinter City, Transfer, Travel and Mobility

The new generation Sprinter Transfer, Sprinter Travel, Sprinter City and Sprinter Mobility are about to usher in a new era in minibus transport from Mercedes-Benz Minibus GmbH. The four model series encompass a range of twelve basic models. The new programme comprises five lengths ranging from 5.9 metres to 7.7 metres, all based on the Mercedes-Benz Sprinter. The permissible gross vehicle weight ranges from 3.5 tonnes to 5.0 or 5.5 tonnes.

Sprinter Transfer: numerous variants with room for 12 to 22 passengers

Four different length variants (5.9, 6.9, 7.3 and 7.7 metres) and three different weight ratings (3.5, 3.88 and 5.0 tonnes gross vehicle weight) combine to produce five basic models in the new Sprinter Transfer programme, for use in rural and shuttle applications as well as day excursions. The product range extends from the Sprinter Transfer 23 to the Sprinter Transfer 55, which has room for 19 to 22 passengers.

While the Sprinter Transfer is a highly attractive vehicle featuring large, flush-mounted side windows and a stylish character line on the flanks to emphasise its dynamic character, it is also fitted with broad rubbing strips on the side, which underline its practical utility. The Sprinter Transfer 55 is equipped as standard with a complete bus-type rear end featuring a built-in luggage compartment flap. The ceiling, interior panelling and trim, stowage facilities and seats all combine to create a light and airy feel in the passenger compartment. Likewise, the use of high-grade materials once again underlines the high quality standards of the Sprinter Transfer.

The completely new seat design bears the name of “Inter-Star Sprinter”. As an optional extra, the travel comfort can be further enhanced with reclining backrests, fold-down armrests along the aisle, stowage nets attached to the backrests and fold-away tables with cup holders. Further options for enhanced comfort include a ventilation duct complete with air nozzles, roof-mounted air conditioners and reading lamps.

Sprinter Travel: equipment for the very best in travel comfort

The new Sprinter Travel offers a high level of comfort for excursions and long-distance travel. It is available in three variants: the Sprinter Travel 45, 55 and 65 (7.3 metres and 7.7 metres in length). The Sprinter 55 is fitted with a complete bus-type rear end. The Sprinter Travel 65 is characterised by a distinctive body with large windows and a panorama windscreen. The flagship model also stands out due to a bus-type rear end with luggage compartment flap and a large rear window.

The appointments are truly impressive: the vehicle is fitted with “Travel-Star Sprinter” seats, complete with a range of comfort features such as reclining backrests and fold-down armrests along the aisle. The standard equipment ranges from luggage racks and service sets with adjustable air nozzles, reading lamps and tour guide call buttons to an air conditioner for the passenger compartment and the independently controllable Tempmatik climate-control system for the driver.

Sprinter City: the low-floor urban minibus variant

The new Sprinter City is a real specialist for regular-service applications. Whereas the compact Sprinter City 35 (6.9 metres long, max. 22 passengers) is based on a modified panel van, the second model, the Sprinter City 65 (7.7 metres long, max. 28 passengers) is instantly recognisable by its separately mounted bus body. Featuring outward-opening double doors with a clearance width of 1250 mm, both models are predestined for city service. An entry height of only 250 mm leads into the low-floor area. Two low steps lead up to the rear of the Sprinter City. Passengers are accommodated in new City-Star Eco seating with upholstered seats and backrests.

The urban bus is powered by turbodiesel engines with a standard output of 80 kW (109 hp) for the Sprinter City 35 and 110 kW (150 hp) for the Sprinter City 65. Power transmission is via a five-speed converter transmission. A retarder, air suspension at the rear axle and a vehicle “kneeling” facility for easier boarding and alighting are standard features of the Sprinter City 65.

Sprinter Mobility: two models for passengers with restricted mobility

The new Sprinter Mobility is designed to meet the needs of passengers with restricted mobility. It consists of two models: the Sprinter Mobility 23 (5.9 metres long, seven seats in the passenger compartment) and the Sprinter Mobility 33 (6.9 metres long, eight seats), which are both based on the panel van of the new Mercedes-Benz Sprinter van series. The vehicle is fitted with an integrated rail-type mounting system for transporting wheelchairs. Available are models fitted with electrically retractable steps for both the passenger door and sliding door as well as a choice of ramp and lift systems at the rear: a mechanical two-piece folding ramp, a linear platform lift and a swivel platform lift. Another new feature is a space-saving underfloor lift inside the vehicle.

The ideal basis for all the models is the new Mercedes-Benz Sprinter

All the new minibuses are based on the Mercedes-Benz Sprinter, which sets new standards in styling and technology. The many highlights include a steering-wheel position similar to that of a passenger car, extra stowage facilities, and remote-controlled central locking. The standard engines of the minibuses are four-cylinder diesel units with 65 kW (88 hp), 80 kW (109 hp), 95 kW (129 hp) and 110 kW (150 hp) of output. All of the engines are low-emission units that comply with the Euro 4 standard and are equipped with a diesel particulate filter.

The highly economical engines of the new Sprinter minibuses boast long intervals between oil changes of at least 40,000 km. A fast and smooth supply of spare parts both in Germany and abroad via 40 EvoBus service centres and about 600 authorised partners also helps to further reduce the already low lifecycle costs.

The new minibuses based on the Sprinter are among the safest vehicles of their class. All vehicles are fitted as standard with the ESP Electronic Stability Programme complete with “Adaptive ESP”, which determines the vehicle’s current centre of gravity on the basis of its actual load. Other standard safety features are ABS, ASR, EBV and Brake Assist (BAS).

Mercedes-Benz Minibus GmbH at the 2006 IAA Commercial Vehicle Show

A Mercedes-Benz Sprinter City 65 will be on show at the 2006 IAA Commercial Vehicle Show in Hanover to showcase the numerous innovations. The 7.7-metre urban minibus is fitted with a separately mounted bus body complete with large windows and a bus-type rear end. The drive train consists of a four-cylinder turbodiesel engine with an output of 110 kW (150 hp) together with a five-speed automatic transmission.
