Dr Heinz-Jakob Neußer on the new Passat B8
We have not simply continued our work on the old Passat but have created an entirely new car. Never has a successor vehicle seen more new technology during a generation change than the new Passat. We have not made any compromises during its development. Despite a shorter vehicle length, we can offer a bigger passenger compartment and increased boot volume. The car’s profile has become flatter and still offers more headroom. But this is not all by any means. On top of that, the new Passat comes with new, economical and more powerful engines, and is up to 85 kilograms lighter than its predecessor.
Dr Heinz-Jakob Neußer, Board Member of Management for the Volkswagen Brand and Head of Powertrain Development of Volkswagen Group.
After 41 years and 22 million Passat vehicles sold, the eighth generation of this successful model is now entering the market. Which special features did you primarily focus on during development? We have channelled our efforts into three fundamental core tasks: comfort, top properties and cost effectiveness. To us comfort means elegance, quality and design; the top properties are low consumption, driving precision, performance, connectivity, up to date driver assistance systems as well as mobile online services; cost effectiveness is selfexplanatory and is of great importance, especially to our corporate fleet customers. What are the fundamental differences with the preceding model?
Is the Passat B8 the benchmark for assistance systems across the Volkswagen group? Yes, assistance systems like the ACC and Lane Assist have been further developed; a pedestrian recognition feature has been added to the city emergence brake function. New assistance systems like Traffic Jam Assist, Emergency Assist and Trailer Assist have been installed for the first time in the new Passat. All in all, our customers will be supported during driving so they can concentrate more closely on the road.

The New Passat
Eighth Generation Innovation The Passat has been an integral part of the Volkswagen vehicle range for over 4o years: a classic that has been continuously developed and improved. The eighth Passat is the new high-tech business class by Volkswagen. Boundaries are overcome with new technologies and new design. At the same time it still remains a Volkswagen, a car for all. It got its name in 1973, by the way, from the trade winds (called Passat in German) that blow uniformly across the seas and facilitate travel for sailors as well as pilots. While the Passat is two millimetres shorter viewed from the outside, a lot of room was gained inside. The interior is 33 millimetres longer so passengers in the back seat now have a total of 116 millimetres of legroom. For this, the wheelbase has been extended to 2.79 metres. The new Passat is 14 millimetres lower than its predecessor and the windshield is now about 3o millimetres closer to the driver. The new Passat scores in the weight category as well: it weighs up to 85 kilograms less than its predecessor. Almost half of this weight reduction, up to 4o kilograms, is due to its engine, followed by its body and equipment that weigh up to 33 kilograms less than in its predecessor. This is made possible by its innovative lightweight steel construction and use of advanced materials. The developers saved nine kilograms of weight in the chassis by using lightweight metals. Regarding electrics, ingenious design saved about three kilograms across the electronics and the electrical system. The
aerodynamics were also improved, benefitting fuel consumption. The drag coefficient (see glossary), a measure of the aerodynamics of a vehicle, is about five percent lower than that of its predecessor because flow losses have been significantly reduced. These are caused, for example, by air turbulences. The shape of the rear of the vehicle reduces tail lift and thus improves the balance of the car, without adversely affecting flow resistance. A high proportion of flow losses are caused by a rugged underside, as air turbulences can occur there at many components. This results in the car consuming more fuel. The underbody panelling of the new Passat has been extended so it could be made much smoother. The radiator grille and the air intakes of the Passat are adapted to this particular engine to achieve the necessary balance between cooling and air flow reduction.
The new Passat is available as a saloon or an estate car. Optimised technologies, adapted materials and new components perfect both models.

The Engine
The Right Motor for Every Requirement Volkswagen has further developed its engines for the Passat with the aim of reducing fuel consumption, without having to compromise comfort or performance. This balancing act has succeeded: the new Passat B8 is up to 2o percent more economical than its predecessor. It remains dynamic and provides sufficient comfort for long-distance drivers. The BiTurbo diesel engine is a new, highly efficient four-cylinder from the Volkswagen range.
BiTurbo TDI The new 2.o litre four-cylinder BiTurbo engine for the Passat has the highest specific output of all mass-produced, four-cylinder diesel car engines by Volkswagen. Volkswagen installs this engine with a seven-speed dual-clutch transmission and permanent all-wheel drive. To reduce interior engine noise, a centrifugal pendulum (see glossary) is used in the BiTurbo diesel engine. The Modular Transverse Matrix for diesel vehicles has been extended in the course of the development of the BiTurbo with a high-performance cylinder head. The air intake and exhaust gas line have been optimised in order to keep the pressure loss low. The supercharger assembly (see glossary) facilitates charging pressures of up to 3.8 bar. Various components were adjusted to withstand the maximum combustion pressure of 2oo bar: the crankshaft is made of a high-strength steel alloy, the connecting rods have been reinforced in the area of the stems. The pistons were newly developed and optimised in their geometry, the piston pin diameter was increased to three millimetres. The injection system of the BiTurbo has also been redesigned to enable the high engine output: the injection pressure was increased to 2,5oo bar. For this, the components of the injection system had to be redesigned, including the use of high strength steel materials. The emission control of the BiTurbo is installed close to the engine so that it heats up very quickly and almost works right from standstill. This way, the limits of the Euro 6 emission standard are easily met.
TDI New turbochargers with variable turbine geometry were developed for both the 88 kilowatts and 11o kilowatts TDI engine power variants. The adjustment of the turbine vanes is done via pneumatic control with position feedback. Flow dampers, which are arranged downstream of the turbocharger, are used to optimise the acoustics of the charging. As part of its development, the levels of aerodynamic efficiency were consistently improved in order to achieve maximum boost pressure at full load and low fuel consumption at part load. As a further thermodynamic optimisation, the concept of a water-cooled charge air cooler, integrated in the inlet manifold was refined. An essential feature is the onepiece, cast housing into which the cooling cassette is inserted and welded. It is vacuum brazed and mounted on one side in this design. The coolant plates of the cassette operate based on the counterflow process. Turbulated sheet metals ensure a uniform distribution of the coolant flow. These and other minor optimisations further reduced the coolant and air pressure drop with high thermal efficiency at the same time.

TSI The petrol engines were further developed for use in the Passat. They quickly reach their optimum operating temperature and allow for comfortable car heating. The consumption of the entire vehicle was also reduced by up to 2o per cent with the new TSI engines. They are available in two power versions: the first version with 92 kilowatts and the second with 11o kilowatts and cylinder deactivation. The cylinder deactivation shuts the second and third cylinder off or on. The engine operates under higher load in two-cylinder mode with greater efficiency. The second and third cylinders are switched on and off with electromagnetic actuators. The TSI version of the Passat B8 saves up to 1.2 litres of gasoline per 1oo kilometres in the.

Outlook The goal is clear: the CO2 emissions of the vehicle fleet must be reduced to 95 grams per kilometre by 2o2o. Volkswagen consistently pursues this goal and 2o15 will see the market launch of the Passat as a plug-in hybrid. Equipped with a petrol engine and an electric motor, both the saloon and estate can drive up to 5o kilometres purely on electricity and therefore emission-free; the total range is approximately 1,ooo kilometres. In the hybrid version too, the Passat reaches 1oo kilometres per hour in under eight seconds and has a top speed of more than 21o kilometres per hour. The lithium-ion high-voltage battery can be charged with an external charging socket.

The New Business Class The Design of the New Passat
The eighth generation of the Passat shows a design that combines stylish clarity with a high degree of power. Both variants, the saloon and estate, appear more elegant and sporty than their predecessors. While retaining all its functional virtues, the new Passat has noticeably gained charisma, exclusivity and dynamism.
A band of air vents lies across the entire width of the interior, underneath it there is an ambient light that continues in the doors.
When looking from the outside, one first notices the significantly shorter body overhangs, the distinctly larger wheels and extended wheel base; in total the track width of the Passat has become larger (see page 3). Nevertheless the Passat still has almost the same compact dimensions as its predecessor. The optimised engine position has significantly lowered the bonnet, and the windscreen has been moved back. These technical measures have enabled the Volkswagen design team to create sporty proportions that exude sovereignty and visual presence. The sharp character line on the side of the vehicle starts at the front headlights and ends behind the rear side window. The door handles are installed precisely in the underlying shoulder line. The front of the Passat is designed three-dimensionally and has a prominent grille, which is connected to the headlights. In the lower part of the bumper, the width of the new Passat is additionally emphasised by
the air inlet and externally positioned fog lamps. The interior has been designed with the intention of creating a light and generous sense of space, which the designers realised with a slim and horizontally structured control panel. The front door panels are stylistically incorporated into this design. The digital instrument cluster displays all vehicle information and user contents. Depending on the situation, this information can be controlled or additionally switched on. The infotainment system can be displayed in the central TFT screen and in the Active Info Display. These functions are controlled by using the steering wheel buttons. In addition, in the eighth generation Passat important driving information is projected in easy to read, coloured graphics into the field of vision on a head-up display. Here, different colours are used to distinguish the various assistance systems, navigation instructions and warnings.
The new Passat LED headlights feature the brand’s familiar light signature. The two-part rear lights have striking light graphics: during braking, the horizontal light signature switches to a vertically arranged signature brake light so increasing the signalling effect.

Technology for Safety Premiere for Assistance And Safety Systems
Some technological components premiere in the new Passat: head-up display and Trailer Assist make it easier for the driver to stay in charge. But they are only the peak of what the Passat has to offer in both versions, a variety of assistance and safety systems as well as other highlights are available to the driver.
Active Info Display The optional Active Info Display turns the instrument cluster into an interactive experience. It allows for different driving information to be displayed digitally at the same time in a 12.3-inch TFT display. This way drivers can change the available info profiles according to their requirements and receive additional information in the central area of the speedometer and the rev counter. The information profile navigation gives the driver the option of making the navigation map appear in the centre of the instrument cluster. To this end, the size of the speedometer and rev counter are reduced in order to achieve an optimally sized navigation map. All information of importance to the driver is still displayed.
Head-up display For the first time Volkswagen offers a head-up display. On it all important information and warnings are displayed directly in front of the driver by means of a retractable glass pane. The driver is less distracted and does not tire so fast, which increases safety for all road users. The driver can chose which information (e.g. speed assistance systems, navigation) is displayed on the head-up display using the infotainment system. The glass pane may be aligned with the driver's seat position; the brightness of the display automatically adjusts to the ambient brightness. To the driver’s eye, the information appears to be just under two metres in front of the car on the road. When the driver does not want to use the head-up display, the glass is retracted in the instrument panel and sealed dustproof with a lid.
Trailer Assist Manoeuvring a trailer is a challenge for many drivers, especially when reversing. For this Volkswagen offers the Trailer Assist optical assistance system. The assistant takes over the steering, after it is turned on, the driver only needs to operate the accelerator and brakes. First, the driver must choose the direction, shown in the display, which can be gradually set via the mirror adjustment switch. While driving, the driver can adjust the desired direction of travel at any time or turn Trailer Assist on or off. If the driver accelerates too much, the system automatically brakes.

Mobile Online Services and Media Control + App Car-Net, the umbrella brand under which Volkswagen markets its mobile online services is available for the first time in the new Passat with the Guide & Inform service package. Destination Import, for example, allows the driver to transfer his own destinations to the Passat via the online customer portal before setting off, the petrol stations service evaluates this data and, accordingly, always shows the most convenient service station in the area – it can then navigate the driver to the nearest petrol pump. Searching for a parking space is also no longer a problem thanks to Guide & Inform: free parking spaces are displayed automatically. In addition to the Guide & Inform services, the new Passat comes with Mirror LinkTM. This allows you to connect your smartphone via the USB interface to the vehicle. You can then operate the smartphone remotely using the infotainment system display. Additionally, the infotainment system can be remotely operated, thanks to Media Control + App. Passengers in both the front and back seats, for example, can change the radio station or volume and start or stop navigation.
Traffic Jam Assist and Emergency Assist The new Traffic Jam Assist and Emergency Assist driver assistance systems are based on the functions of the Lane Assist lane departure assistant and the Adaptive Cruise Control ACC. Traffic Jam Assist enables comfortable, automated driving in so-called stop and go traffic, at speeds up to 6o kilometres per hour while staying in lane. Emergency Assist enables partial vehicle control in a medical emergency. The assistant is activated if, after repeated requests by Lane Assist to take over, the driver exerts no vehicle control (for example steering, accelerating or braking). The objectives of the assistant therefore are to alert the driver and to warn other road users and, ideally, ensure a controlled stop of the vehicle in the same lane.
City Emergency Braking system with Pedestrian monitoring In the new Passat, our famous city emergency braking function is extended to detect pedestrians. This function consists of an optical and acoustic warning, the second step is an automatic braking intervention. Up to a speed of 65 kilometres per hour, the consequences of an accident for the pedestrians involved can be reduced.
G lossary Supercharger assembly: the supercharger assembly includes all components that belong to the turbocharger, such as manifolds, compressors and turbines.
Centrifugal pendulum: an engine in operation generates torsional vibrations,

which affect the driving noise and sensation. The centrifugal pendulum is a speed-dependent damper that reduces these oscillations. Drag coefficient (cd value): this value quantifies how streamlined an object is. It has no unit, is also called cd value,
and for cars is usually between 0.2 and 0.4. The value is a measure of the slipperiness of a body regardless of the driving speed, air density and the front surface of the vehicle.
