Scania’s strategy is to provide its customers with complete buses and coaches in every segment and thus keeps extending its portfolio of such vehicles via the worldwide Scania network.

“Our growth strategy includes a commitment that Scania customers should be able to rely on support from one single point of contact, with parts, maintenance and repairs via our regular sales and service network,” states Melker Jernberg, Senior Vice President Buses and Coaches at Scania. “This will minimise hassle and maximise uptime, enabling our customers to focus on what they are best at: running their operations as profitably as possible.”

Regular service Occasional service

The latest addition, the Scania Touring, is a 2- or 3-axle high-decker coach built in co-operation with Chinese bus manufacturer Higer. Offered at a competitive price, the vehicles are built according to Scania standards with full service market support from Scania.

The stylish Scania OmniCity is a full low-floor city bus. Options include diesel/biodiesel (EGR), gas/biogas and ethanol engines, all meeting the EEV emission standard. A new adjustable dashboard can be specified that meets Germany’s VDV requirements. Many of the Scania OmniCity buses delivered in Scandinavia over the years have been equipped to run on ethanol.

Two vehicles are being exhibited at IAA 2010:

Scania Touring 4×2 and 6×2 – new high-decker coaches

Suitable for occasional service as well as regular intercity service, the brand new Scania Touring was introduced in 12-metre 4×2 form at the latest Busworld exhibition in Kortrijk. The range has now been extended by adding a 13.7-metre 6×2 version. Both are high-decker coaches with generous passenger capacity: 4×2: 49+1+1 seats; 6×2: 57+1+1seats.

The Scania Touring has been crafted by Scania’s styling department and is developed in cooperation with Higer. Typical Scania traits are the rounded wedge-shape at the front and the rounded corners that reduce drag. The distinctive front and wraparound windscreen flow smoothly into the window line along the sides. The sculpted wheel arches and characteristic tail wrap up all styling elements into a statement of quality and solidity.

Two trim levels are offered, Comfort and Premium, both including a mid-mounted toilet cabinet and an optional kitchenette. A selection of co-ordinated colour schemes for panels and upholstery can be combined to provide a relaxed and pleasant atmosphere. Stitched leather upholstery with contrasting seams is optional. Roof-mounted air conditioning and convector heating are standard, auxiliary heating an option. Side and rear windows are double-glazed and tinted. The AV equipment includes 17-inch LCD monitors at the front and in the centre. Aft of the centre door is an optional co-driver’s bunk with an intercom facility to communicate with the driver. The driver station has driver-friendly ergonomics and ample seat and steering wheel adjustments.

The 400 or 440 hp 12.7-litre Euro 5 engines comply with Euro 5 emission standards. The 360 hp 9.3-litre engine offered as an option on the 4×2 complies with EEV, which is even more stringent. All engines feature Scania EGR and XPI common-rail fuel injection and can run on up to 100% biodiesel. Euro 4 engines are also available. The 12-speed Scania gearbox is offered with a choice of fully automated (Scania Opticruise with automatic clutch) or electronically controlled manual gearchanging (Scania Comfort Shift). The powerful Scania Retarder is a common option that provides safe and convenient downhill cruising.

Full air suspension is standard, with optional independently sprung front wheels. The rear axle set-up on the 6×2 version features a steering tag axle behind the drive axle. Electronically controlled disc brakes with ABS are standard.

Scania OmniCity – full low floor and VDV dashboard

Forming part of Scania’s comprehensive range of city and suburban buses, the Scania OmniCity is a full low-floor 12 m city bus that is also offered as a double-decker for the UK market. There is also an 18 m articulated version. The low-floor layout is highly flexible, offering high passenger capacity and fast circulation for busy inner-city routes. The driver station can now be specified with an adjustable dashboard that fulfils the German VDV requirements.

Powertrains include engines (all complying with EEV) for all currently available commercial vehicle fuels: diesel, biodiesel, natural gas, biogas and ethanol. The diesel engines are 9.3-litre 230 or 280 hp EGR units without any need for additives. The 9.3-litre gas engines are rated at 270 or 305 hp. The ethanol engine is an 8.9-litre unit producing 270 hp. All engines are combined with ZF automatic gearboxes with integrated retarders.

The Scania OmniLink range comprises 2- and 3-axle low-entry buses up to 15 m long, as well as an 18 m articulated version. Powertrain options are similar to those of the Scania OmniCity, plus a 320 hp diesel/biodiesel engine for the articulated version. The low-entry front section combines fast, easy access with maximum seating capacity in the higher rear section. All seats are forward-facing.

All Scania OmniCity and Scania OmniLink models are built at the Scania factory in Słupsk, Poland, which has just been extensively upgraded to increase capacity and flexibility and further boost productivity. The all-aluminium bodywork on these buses provides sizeable weight savings as well as easy recycling of bodywork components. Several door configurations and interior layouts are available to tailor the vehicles precisely to any type of local requirement.

Other models

The Scania bus and coach range offered in Europe also include the Scania OmniExpress in a choice of heights and specification levels. Also on offer in co-operation with Spanish bodybuilder Irizar, are several stylish versions of the Scania Irizar i4, Scania Irizar Century and Scania Irizar PB. Full parts and service support is secured via the Scania network

Developed in-house as part of Scania’s new engine platform, Scania’s new 270 and 305 hp gas engines for trucks and buses are now ready for the market. The engines come complete with Scania engineered fuel supply and storage systems tailored to the requirements of distribution trucks and city buses, respectively.

Trucks: Gas engines can be specified on Scania P-series trucks (P 270 and P 310) with short, day or low-entry cabs, allowing all types of city operation. Chassis configurations are either 4×2 or 6×2 rear-steer, in both cases with full air suspension. An Allison 6-speed automatic gearbox is standard, with or without integrated retarder.

City buses: Gas engines are available on Scania OmniCity (low-floor) and Scania OmniLink (low-entry) buses specified for inner-city operation. Starting with 12 m 4×2, the gas engines will also be available in other configurations from 12 to 18 m. The transmissions are 5- or 6-speed automatics from ZF with integrated retarder. Chassis modules are available for local bodybuilding.

Engine management and ignition

Gas supply and air intake

Gas engine architecture

The basis is the latest 5-cylinder 9.3-litre engine platform (130 mm bore) used for Euro 5 and EEV (enhanced environmentally friendly vehicle) diesel engines. Modifications include cylinder heads for centrally-mounted sparkplugs, a gas injection system in the intake manifold and a specially adapted camshaft. Low-compression pistons provide the 12.6:1 ratio that is suitable for lean-burn Otto combustion. A small fixed-geometry turbocharger is used with up to 2.5 bar (abs.) boost pressure (for quick response to throttle variations) combined with a wastegate with automatic performance control.

Combustion is very lean and controlled by a closed-loop lambda sensor system and an air mass gauge is fitted in the intake. The engine management system automatically adapts to the gas quality. This is advantageous when running on biogas or mixes of biogas and natural gas, where some variation in gas quality might be encountered.

Gas engines with diesel performance

The Scania engine management system controls a slave system from Bosch. This means that the engine management can be fully integrated in Scania’s diagnostics tools to provide convenient trouble-shooting for Scania service technicians. The performance has been tuned to provide diesel-like power and torque delivery, making it easy to adapt the characteristics to the automatic gearboxes fitted as standard:

Customised tank layouts

The gas tank installations are adapted to suit the needs of these market segments, i.e. distribution and refuse collection trucks and city buses. The operating pressure is 200 bar and the remaining fuel is displayed in percent on the fuel gauge, with a 10 bar ‘get-home’ margin when zero is indicated. The installations are certified according to ECE R110.

Trucks: Eight 80-litre composite gas tanks providing a capacity of 640 litres and a typical operating range of up to 200 km. The tanks are mounted in compact 4-tank packages on each side of the chassis. Besides being strong and light, a major advantage of composite tanks is that the useful service life is 20 years, compared to around six years for steel tanks. The overall weight of the tank package is more than 400 kg lighter than steel tanks of the same size.

City buses: Four 320-litre aluminium tanks are mounted in a package on the roof, close to the front axle centreline to optimise weight distribution (the roof hatch locations have been adapted accordingly). With 1,280 litres onboard, the typical inner-city operating range is around 500 km. The filler nozzle is located behind the front hatch on the door side. A G-sensor shuts off each tank and the gas supply to the engine in case of an impact (can be reset by the driver). A package of eight or ten 150-litre composite tanks for roof mounting is supplied with chassis modules.

With the addition of the latest generation of gas engines, Scania provides a uniquely broad choice for its customers. Customers have a choice of vehicles that operate on all fuels that are currently available on the market. In addition they can opt for their preferred emission control technology.

Scania engines are renowned for economy, longevity and driveability. This tradition has been carried through several generations of commercial vehicle engines and is more tangible than ever in the latest additions. Engine-by-engine, the torque-to-power ratio is highest on the market, giving class-leading driveability and driver appeal, factors that also translate into fuel efficiency and a relaxing drive.

The latest engines include state-of-the-art technologies that pave the way for Euro 6 and beyond, for example common-rail fuel injection, variable-geometry turbocharging, EGR or SCR emission control and in-house developed engine management controlling the performance of all systems and the interaction with other systems on the vehicle, e.g. gearbox, retarder, brakes, chassis, cab and bodywork systems.

One of the latest and most remarkable engines based on this platform is the 16.4-litre V8 producing a remarkable 3,500 Nm and 730 hp, making it the highest rated truck engine on the market. Like Scania’s other Euro 5 engines, this engine has proved itself in operation with customers and journalists, turning in an attractive combination of fuel economy and performance.

All viable fuels

Scania customers have a choice to specify vehicles for all currently available commercial vehicle fuels. Operations can thus be tailored precisely to local conditions, incentives and requirements, while in each case retaining the best possible operating economy.

Diesel and biodiesel: Scania Euro 4 and Euro 5 diesel engines are all compatible with up to 100 percent biodiesel, provided that the maintenance is adapted according to Scania’s recommendations. Biodiesel offers CO₂ savings of around 35 percent¹. Performance is slightly down compared to diesel (840 g density), particulate emissions are almost halved, whereas NOx emissions rise slightly. Biodiesel is the only viable alternative fuel for long-haulage. It is suitable for all types of operation and can be mixed freely with both fossil and synthetic diesel.

Gas and biogas: Scania’s new gas engines are suitable for trucks and buses operating in urban conditions. Purpose-designed tank packages in most cases give a sufficient operating range for a full day’s driving. The gas engines are certified to comply with the EEV standard, i.e. with even lower HC emissions than Euro 5, and are designed to run on natural gas or biogas, the latter with the potential of reducing CO₂ emissions by 70 percent.

Ethanol: Environmentally oriented truck and bus customers in search of a greater operating range than gas or the convenience of a liquid fuel can specify Scania’s 270 hp ethanol engine that operates with compression ignition at high efficiency, just like a diesel engine. The lower energy content of ethanol means that fuel consumption is higher than for a diesel engine, but CO₂ emissions are 70 percent lower, giving highly attractive environmental benefits, as noted during more than 20 years’ bus operation in the city of Stockholm.

Scania’s modular approach

Scania’s engine range is extensively modularised with shared architecture and components that facilitate repairs and parts supply, as well as the training of sales staff and service technicians.

The modularity extends to layouts, components and dimensions. Some pre-development work is carried out on single-cylinder test rigs, where all relevant parameters can be varied and tested individually. Once a timing, injection, combustion or emission concept has been chosen, further development and testing takes place on complete 5-, 6- and 8-cylinder engines.

¹⁾ The CO₂ reduction figures are based on the Directive 2009/28/EC on the promotion of the use of energy from renewable sources (EU-RED).
²⁾ 360 hp for buses and special applications.

Ultimately, each and every engine variant is optimised for performance and economy in a given application. Scania has made a strategic decision to have in-house competence in all areas that are of strategic importance. In engine development, this means everything from materials technology, design, testing and manufacturing, as well as all hardware, software and injection development.

The 130 mm bore represents the latest engine platform, which is adapted for future technologies and material strength requirements, needed e.g. for Euro 6. Although newly developed from scratch, many components and the general layout are shared with the other engines.

EU emission standards

Depending on market conditions, customer requirements and legislation, Scania provides an engine that covers all emission levels from Euro 3. For some applications, the added complexity of tighter emission control may be undesirable, e.g. in tough off-road construction work, far off the beaten track, or in countries where low-sulphur fuel or exhaust treatment fluids are unavailable.

“There is a lot we can do here and now! In close co-operation with our customers, we can help to optimise their operations, reducing both fuel costs and CO₂ emissions, while boosting lifetime profitability,” says Executive Vice President Martin Lundstedt, who is in charge of sales and marketing.

“Ecolution by Scania makes our comprehensive green product portfolio immediately visible for our customers. Included in the package is a unique combination of long-term vehicle follow-up and personal support for drivers to make sure everything remains in top shape.

“By opting for Ecolution by Scania, our customers will get the lowest possible CO₂ emissions and fuel consumption, both on diesel and on renewable fuels,” remarks Mr Lundstedt.

The strategy is to reduce CO₂ emissions by making the best possible use of both products and services. The introduction is starting with customised offers for trucks and buses in Germany and Sweden, soon to be followed by a general roll-out in Euorope.

Scope

Ecolution by Scania comprises several elements to secure lasting CO₂ performance improvements on vehicles in operation.

This is Ecolution by Scania

• Targeted back-office specification support for the sales force.
• Transport analysis, including cost analysis and expected fuel consumption.
• Vehicle specified to minimise fuel consumption and thus CO₂ emissions.
• Driver training adapted for each driver’s needs and for the application.
• Driver follow-up (coaching) at agreed intervals.
• Regular fleet performance reports.
• Special maintenance programme adapted to preserve CO₂ and fuel efficiency.
• Overall carbon footprint analysis performed at agreed intervals.
• Agreement covering up to 3 or 4 years.

Customers opting for the entire offer will be granted an Ecolution by Scania certificate. The individual elements are also available separately, although then not under the Ecolution umbrella.

Packaging

Ecolution by Scania covers all commercially available fuels, i.e. diesel, biodiesel ¹⁾, biogas and ethanol ²⁾. CO₂ optimised diesel vehicles with substantial CO₂ savings qualify in applications where renewable fuel is a less realistic proposition, e.g. in long-haulage.

Vehicles qualify based on the estimated CO₂ savings. For diesel vehicles this is dependent on the savings achieved with the CO₂ and fuel optimised specification and the mandatory parts.

The following elements are mandatory in Ecolution by Scania:

¹⁾ Biodiesel according to EN14214 (e.g. RME, FAME).
²⁾ Ethanol ED95 adapted for diesel combustion.

BREAKDOWN OF ELEMENTS AND EFFECTS

This section explains the main elements of Ecolution by Scania in greater detail and lists potential CO₂ and fuel savings.

CO₂ optimised specification

An optimised specification is developed jointly with the customer using a CO₂ calculation tool. Numerous factors related to transport application and operating conditions are taken into account, as well as experience of previous vehicles. The factors include minimising air drag, rolling resistance and weight, choosing economy revs for cruising, Scania Opticruise, Scania Ecocruise and where viable using renewable fuel.

The tool permits ‘playing around’ with most of the parameters to watch and discuss the effects together with the customer. The result is an estimate of the annual CO₂ and fuel savings. Other exhaust emissions can also be calculated if required. The calculations qualify for inclusion in green public procurement documentation.

In the following diesel truck example the savings are 27 tonnes CO₂ and 6.1 litres/100 km fuel respectively.

Driver training and follow-up

Ecolution by Scania includes driver training focused on economy driving, which will also bring savings in wear-and-tear and reduce the risk of accidents. The training is adapted to suit each driver and application. On average, 10 percent savings are possible, even for a skilled driver.

The driver follow-up included in Ecolution by Scania serves to keep up the savings over time. After the initial training, Scania staff will keep in touch with the drivers and give personal feedback on how they are performing. For long-haulage vehicles, the use of Scania Driver Support is recommended.

Scania will also continuously report any deviations in the vehicle’s performance to the customer and suggest suitable action.

The follow-up information is taken from the Scania Communicator (n.a. with gas engine), which reads performance data from the vehicle’s CAN-bus. This service also forms part of Scania’s fleet management offering.

Maintenance+

Part of the Ecolution by Scania agreement is an extended maintenance programme devised to preserve the CO₂ and fuel savings achieved with the original optimised specification.

The additions include attention to air deflector positions, axle alignment, tyres, tyre pressures, condition of filters and other ‘fuel thieves’.

Annual CO₂ savings

Please note.
The CO₂ reduction figures are based on the Directive 2009/28/EC on the promotion of the use of energy from renewable sources (EU-RED): biodiesel 35%, biogas 70% and ethanol 70% CO₂ saving. These figures take energy content into account and thus include fuel consumption differences. Furthermore the figures are based on a well-to-wheel comparison, which makes sense since virtually all net release of CO₂ comes from the production phase of biofuels.

Other sources may state emission reductions up to 70%, 90% and 100% respectively, depending on fuel sourcing and production methods. In order to use such figures, an approved verification is needed.

One litre of fossil diesel corresponds to 2.7 kg of CO₂ from the tailpipe. A well-to-wheel approach will add some 0.3 kg and the total will be 3 kg CO2.

Buses and coaches on display: Scania OmniCity low-floor; Scania Irizar i4 intercity coach; Scania Irizar PB luxury coach. A Scania OmniCity with ethanol engine is available for test riding.

New engine generation

The stand also proudly displays Scania’s leading engine technology. The relation between power and torque – a traditional Scania strength – is decisive to the performance of the vehicle and all Scania powertrains are optimised for fuel-efficient driving.

The new EGR (exhaust gas recirculation) engines meet Euro 5 emission standards without aftertreatment and without the need for additives – a breakthrough in engine technology. The comprehensive engine range is complemented by further Euro 5 and EEV (enhanced environmentally friendly vehicle) engines that meet the toughest existing environmental standards in Europe.

Scania’s new 9-litre diesel-ethanol engine gives operators the option of running on the most readily available renewable fuel on the market with CO2 savings of up to 90%.

Driver focus

For Scania, the driver is always at the centre because he or she has a decisive influence on road safety, fuel consumption, operating economy, accident avoidance and environmental impact. The show also marks the launch of the Scania driver competition “Young European Truck Driver 2009″. Drivers interested in participating are welcome to register on the Scania stand.

Services galore

The issue of efficiency also revolves around the many services offered by Scania. Scania’s service portfolio comprises some 30 different offers, a selection of which are presented on the stand. Also highlighted is Scania’s new driver training platform that complies with the EU directive on driver competence now entering into force.

Scania is extending its rental offer in Germany by also including curtainsider or reefer semitrailers.

Long dashboard with Scania Colour Plus instrument cluster

Rising fuel prices, increased environmental awareness and tougher demands on driver skills make it necessary for transport operators to have access to more information in order to optimise operations and boost profitability. Scania’s customer commitment therefore goes one step further.

The new service allows operators to interpret and analyse vehicle and driver data in a transparent way. Since it is equally useful on a mixed fleet of vehicles, this will help any operator to keep down costs, increase revenues and facilitate environmentally adapted driving.

The service provides a clear and simple overview of the fuel consumption and performance of individual vehicles, as well as tracking and information on how each vehicle has been driven – information that can be used to help improve profitability and reduce environmental impact. Included in the service is a logging and communication unit on-board the vehicle (Scania Communicator), a communication subscription and a web-based office interface.

Data collector and portal

Scania Communicator collects data from the vehicle. On the office portal, the data is analysed against parameters set by the customer and then reported in an easy-to-understand manner, highlighting where action can be taken. Individual vehicles and drivers can be studied, as well as groups of vehicles or the whole fleet.

The information is useful from a cost and environment perspective in terms of fuel consumption and vehicle performance. The information can then be used as an effective tool when training drivers in fuel-efficient and environmentally suitable driving, which in turn impacts maintenance costs as well as road safety.

The portal also offers other operational efficiency management tools, including vehicle tracking and exception reporting, maintenance planning and environmental reporting to name just a few.

Digital tacho data

During 2009 a new functionality will be introduced on the Scania Communicator that allows wireless downloading of driver card as well as digital tachograph data to a secure storage location where it can be viewed and analysed. This will require the use of next generation digital tachographs due for release from the tachograph suppliers during 2009.

On-board support

Scania offers several on-board solutions that support the driver’s work and facilitate interaction with the office.

The Scania Interactor range of on-board computers also supports data collection and analysis and is available in two sizes: Scania Interactor 300 and 500 with 7-inch and 10-inch touch screens.

The Scania Interactor 500 is an open Windows-based platform that permits free installation of third-party software, whereas the 300 is intended for pre-installed software. Both allow for the same functionality with Scania fleet management software and now include truck-adapted navigation for Germany, UK, France and Benelux as standard.

Scania Driver Log and Scania Order Support are services designed for simple integration into administration and order handling systems at the office.

Various national fleet management packages are available from Scania distributors.

Scania’s aim is to develop vehicles that lead the market in terms of total operating cost and trouble-free ownership. This is based on a business model that takes the customer’s cost and earning potential into account.

Scania vehicles are designed to perform as much useful work as possible on the roads and to spend as little time as possible in the workshop. They are also renowned for their fuel economy, a reputation that has been earned during more than a century in the commercial vehicle business. In addition, they are designed to appeal to drivers in terms of performance, response and ergonomics, factors that help operators recruit and keep good drivers. This concern for the customer’s business has given Scania vehicles outstanding residual value in the market – another factor that contributes strongly to the customer’s bottom line.

Here are some realistic steps to optimise fuel performance that are available to most operators. The figures cannot be added, but they give an indication of the effect of individual actions.

Scania Driver Training

Driver training saves around 10%

Fuel savings of 10% on average are possible as a result of professional driver training. Active monitoring of driver performance and regular training are needed to maintain this level.

4 km/h saves up to 3%

A simple measure like lowering the normal highway cruising speed by 4 km/h will save up to 3% of fuel and a huge pile of euros.

Electronic support saves up to 10%

Automated gearchanging makes driving easier and helps drivers perform consistently, while reducing wear and tear on the vehicle. Scania Opticruise has been found to save up to 10% of fuel for an untrained driver.

Scania Ecocruise, the smart cruising software, can save 3-5% on top of that by using techniques well-known to any driver trained in eco-driving and with negligible time loss in a working day. Not accelerating when climbing a hill until the crest levels out and using momentum at the bottom of slopes are two of the secrets.

Scania has also developed acceleration control, a system that promotes smooth driving and boosts passenger comfort in city buses. It also reduces wear and tear on brakes and powertrain and typically saves up to 6% of fuel. Will also save fuel for some city distribution applications.

Vehicle optimisation

• Continuous monitoring of vehicle and driver performance makes it possible to take action with minimum delay.
• Regular maintenance takes on a crucial role to make sure everything stays in optimum shape – faults can be detected before they have a chance to cause much harm.
• Get the gearing right for the application. At 40 tonnes with today’s high-torque engines, going for economy gearing, i.e. cruising below 1200 r/min instead of 1350 r/min, will save up to 3% of fuel without any severe effects on driveability.
• Keeping down the unladen weight will automatically save fuel. Specifying low-weight options could reduce weight by 500 kg and save up to 1.5% in hilly terrain.
• Checking axle alignment pays off. Adjusting a 1° misalignment may save up to 3% of fuel.

Optimising air drag saves 5-6%

Fitting air deflectors is the first obvious step to improve air drag on a tractor unit. This alone saves some 10%. But further refinements are possible:

• Adjusting the roof air deflector from 10 cm too high or low will save up to 3% of fuel.
• Fitting Scania’s rubber extensions on the side air deflectors and sideskirts will save up to 1.5%.
• Avoiding auxiliary lights, air horns and other embellishments on the roof will save up to 1.5%.

And then all sorts of improvements are possible on the semitrailer, of course. A difference of 5% in fuel consumption between semitrailers is not uncommon.

Tyre pressures 1-2% per bar

One bar too little in the tyres may cost 1-2% of fuel. Keeping up the tyre pressure at all times will secure consistent rolling resistance, minimum tyre wear and maximum road safety. An easy way is to specify tyre pressure monitoring (TPM), a system that allows pressures to be read from the cab and that alerts the driver if the pressure drops in any of the tyres. In addition, around 5% of fuel can be saved by specifying tyres with low rolling resistance.

How much fuel do you want to save?

So saving fuel – and reducing the environmental impact – is an important part of the game. It all boils down to these crucial factors:

• The driver can provide the biggest short-term fuel savings.
• Vehicle optimisation is vital in the long term.
• Follow-up and monitoring are essential to secure consistent fuel performance.

For a typical 40-tonne European combination running 200,000 km annually, the fuel savings can be translated into litres and euros ():

Scania Irizar Century

Scania Irizar range

Powertrains with EGR for maximum convenience

Scania’s bus engines are all equipped with Scania EGR, exhaust gas recirculation, requiring no aftertreatment equipment or additives on-board the vehicle. All engines up to 360 hp are available as EEV (enhanced environmentally friendly vehicle). Engines that meet Euro 5 emission standards extend up to 480 hp.

The new 9-litre 360 hp EEV engine for the intercity and coach segments provides a lightweight alternative for 2-axle coaches and 2- and 3-axle intercity buses.

Torque delivery and driveability are outstanding for all engines in the new range, minimising the need for gearchanges and providing a relaxed ride. The new bus range is also available with Euro 4 and Euro 3 engines.

Gearbox options include manual gearboxes with Scania Comfort Shift, an electronic gearshift servo, as standard. Automated gearchanging, Scania Opticruise, is optional, as well as fully automatic ZF transmissions.

Unique renewable fuel solution

Scania also offers operators the unique possibility of specifying a diesel engine adapted to run on ethanol in city buses. The technology is highly efficient, since combustion takes place according to the diesel principle, and has been proven in 20 years of busy city traffic in the Swedish capital of Stockholm, for example.

This renewable fuel cuts CO2 emissions by up to 90% if produced in a sustainable way from Brazilian sugar cane. Being a liquid fuel, distribution and handling are exceptionally simple and production of ethanol is booming all over the world.

The diesel-ethanol engine is a 270 hp 9-litre unit with 1200 Nm of torque.

New articulated bus

Scania now offers two types of articulated buses. The Scania OmniCity, which has been sold for more than a decade, is now complemented by a low-entrance OmniLink. The two types are also available as assembly kits supplied to selected bodybuilders.

The new low-entrance articulated bus, which is intended for intercity traffic involving long-distance and BRT systems, has a higher floor from the second axle and rearwards, a layout that provides numerous benefits:

• Greater passenger capacity. No intruding wheel housings in the higher rear section.
• Greater comfort with a maximum number of seats, all facing forward, but less room for standees.
• Disabled passengers or passengers with prams have easy access to the low-floor area via the 1st and 2nd doors.
• Simpler mechanicals and better fuel economy with the longitudinal powertrain.

The version with a full-length low floor is intended for inner-city applications requiring a fast flow of passengers.

The new low-entrance articulated bus is available with the 310 hp 9-litre Euro 4 engine.

Adjustable VDV dashboard

Linked to the VDV instrument cluster is a dashboard for urban buses conforming to the VDV recommendation 234. The recommendation has attracted a considerable following among public transport companies and trade unions in Germany and Spain, for instance. The purpose is to provide a type of standard workplace for bus drivers where they readily feel at home and know the whereabouts of all vital controls.

Scania has integrated the VDV recommendations into Scania’s new driver station, maintaining the ergonomics while adding the features required. The result is stylish and very driver-friendly. Much appreciated features like the generous steering wheel adjustment for tilt and reach, and pendant pedals are naturally retained. The entire dashboard is also adjustable for reach, moving with the steering wheel when adjusted.

Acceleration control

Passenger comfort and safety are of primary importance to a city bus operator. So is fuel economy and, closely related to that, environmental impact.

Scania is now introducing acceleration control as an option, designed to smooth out the ride when the bus is less than fully laden, eliminating the jerking associated with busy city traffic. This function has been developed at the request of several city bus operators.

The function controls acceleration electronically, taking into account the actual weight of the bus at any time. The preset acceleration value of 4 km/h/s from standstill tails off gradually to 2 km/h/s at 90 km/h.

At speeds above 30 km/h the driver can temporarily override the system using kickdown, for example for overtaking.

The settings of the acceleration control can be adjusted by Scania service workshops to suit individual conditions.

The fuel saving potential is up to 6% in typically busy stop-and-go city traffic. Additional savings result from reduced wear and tear on the powertrain and brakes, as well as from the enhanced well-being and comfort of the occupants.

TPM promotes safety and economy

Tyre pressure monitoring (TPM) is being introduced as an option for all buses. The system alerts the driver if the pressure in any single tyre drops below the preset value, providing invaluable backup for visual checks should something untoward happen. At the same time, the system saves fuel by making it easier for drivers and operators to maintain correct tyre pressures, signalling even the slightest deviation via the central instrument.

Safety features on Scania buses and coaches also include electronically controlled disc brakes all-round, hill-hold for easy uphill starting, emergency braking assistance providing extra braking power in case of panic braking and electronic stability program to minimise the risk of skidding and rollovers.

Faster gearing – more relaxed cruising

A faster 2.73:1 rear axle is now available, enabling a coach to cruise around 1400 r/min at 100 km/h with a standard direct-drive gearbox. The ratios available are 3.42, 3.07, 2.92 and 2.73.

The ultimate in cruising comfort is obtained with the overdrive 12-speed gearbox, available on luxury coaches. Revs are then below 1200 r/min, enabling Scania’s high-torque engines to make the most out of every drop of fuel.

F-series – a long and proud tradition living on

For many years Scania has been able to provide a full-size front-engined bus chassis ex-factory, as opposed to truck chassis that are re-built for bus service post-delivery.

Front-engined buses are preferred for use on poor roads off-highway due to their robustness and easy servicing. The concept has found particular favour in South America and southern Africa, but there is also interest from other regions.

The Scania F-series traditionally has an exceptionally robust chassis frame with extra ground clearance.

The latest F-series features the same components, electrical system and features as the latest bus and truck series, including the new driver station and CAN-bus based electrics.

The first version out is a right-hand-drive heavy-duty 4×2 with 9-litre 230 or 270 hp engine and a horizontal 6-speed manual gearbox to keep down the floor level. This combination provides ample performance and excellent fuel economy for this type of operation.

Scania Fleet Management

Scania’s fleet management solutions are designed to help drivers and operators achieve the highest possible efficiency from their vehicle fleet, while also allowing smooth interaction with the office and other on-board equipment and systems.

Scania’s data logging and communication service has been developed to provide a powerful tool for detailed monitoring and follow-up of fleet operations. The transport operator gets a complete package that provides an overview of how the fleet of vehicles is used, which in turn contributes to lower fuel costs and more perceptive and motivated drivers. The system is fully compatible with a mixed fleet of vehicles.

The service includes an on-board data logging unit, GPS positioning and communication with the office. Data can be read and analysed on the office portal or via an on-board computer, if fitted.

On-board computers are available in two sizes: Scania Interactor 300 and 500 with 7-inch and 10-inch touch screens. The Scania Interactor 500 is an open Windows-based platform that permits free installation of third-party software, whereas the 300 is intended for pre-installed software.
