                                         1 Introduction
        Current trends in the automobile markets and their implication on products and the
resulting requirements for vehicle development will be displayed.
        More complex products to meet growing climate protection goals are at odds with the
strong price pressure and the demand for Low Price Vehicles designed for mobility and
awakening markets.




                                  Figure 1 - CO2-Regulation

        KST Motorenversuch GmbH & Co. KG, Bad Dürkheim, provides state of the art engine
development services. AtTrack GmbH, Gesellschaft für Mobilität contributes through technical
and business solutions, such as the one presented Total Customer Integration (TCI), to master
future challenges in the vehicle industry.

       Two trends are:
    • The demand for sustainable vehicles with reduced CO2 emissions, Figure 1.
    • New Low Entry segment in mature markets and Low Price Vehicles for mass
        mobilization in emerging markets.
       The two trends hold conflicting objectives: the demand for environmental sustainability is
asking for more resources to create and build cars and the complexity of the vehicles will be
greatly increased. On the other hand the Low Price Vehicle (LPV) and price pressure on all
segments require significant simplifications, Figure 2.

                   Use of an outdated platform for saving development costs, i.e. Dacia on a Renault R5
                   platform

                   Radical new platform design having the low cost requirement in mind, i.e. Tata Nano

                                         2 Market Situation
        In 2004 mankind produced 27.5 billion tons of the greenhouse gas CO2 just for energy
reasons [1]. In mature markets, there is a growing environmental awareness, which rises pressure
in terms of legislation and on the market place in general. The rising oil price - more than 100 $ /
barrel only recently – hurts "Cost of Ownership" values and imposes related action on
manufacturers.
        Parallel to this, there are market shifts by weakness or neutrality of the "old" markets and
partly accelerating growth in the "emerging markets". The fastest growing automobile market in
the world is China, with an average annual increase in sales of 0.8 million units / year, followed
by Russia with 0.3 million units / year and India with about 0.2 million units / year [2].
        The growing mobility needs in the emerging markets are stoking the call for the "cheap"
entry-level car. Current market studies assume that even 2010, the world market share in so-
called Low Price Vehicles will reach 13% [3]. To mobilize a large segment of the population
quick and in a cost efficient way can in the transition be performed by reduced product
requirements. Thus, e.g. the One Lakh Car from India takes 4 persons on one hand, but confines
itself with a maximum speed of 100 km / h on the other.
        Market saturation and purchasing restraint in mature markets cause price pressure across
market up to the premium classes. In the medium term it is expected, that the low end segment
will gain over the others. For OEMs, there will be a competitive advantage, being able to realize
a Low Price Vehicle for comparably lower cost. First relevant products such as the Dacia Logan
already entered the market place.

                               3 Two Noteworthy Product Trends
                        3.1 Alternative Fuel Vehicles and Hybridization
        Natural disasters (Hurricanes, tsunamis,…) stoked the discussion on the preservation of
natural resources. Europe focuses on the prevention of the greenhouse gas CO2.




                                                              347
                                  Figure 3 - Alternative fuels

        On the short note manufacturers endeavour to reach fleet goals through friction and
weight reduction measures, such as, for example, energy saving tires,.. . On the transition to new
drive systems, the use of fuels from renewable resources plays an important role, Figure 3.
        An example of the use of new technologies in already existing platforms is the soot filter
for diesel vehicles. The development of the filter causes considerable extra effort in engine
testing, Figure 4. To achieve an optimum deposit rate without too big an increase of the exhaust
back pressure is the target.




                  Figure 4 - The Development of a Diesel Particulate Filter

       The fact that apart from the additional component in the car, the impact of different fuel

                                               348
types has to be tested, increases the testing effort furthermore. But also the cost of systems
integration increases for the OEM.
        Two requirements must be met:
    • Geometric integration, especially if the filters have not be foreseen in the base
        development.
    • Dissipation of the additional heat, without putting other vehicle functions at risk.
        This gets increasingly difficult due to the rising share of electronics in the vehicle. More
and more "hotspots" must share space with more and more temperature-sensitive electronic
components, Figure 5.




                    Figure 5 - Temperature build up in the Turbocharger

        Often, the package size and the density distributions of the physical sizes get rather
complex. Virtual Reality (VR) specifics, such as the deep geometrical representation and the eye
tracking     is    an    essential  aid     to   understand   the     complex      relationships.
The public discussion regarding future propulsion systems initially was polarized between the
Japanese manufacturer’s favourite hybrid technology and the already widespread existing diesel
technology in Europe. Meanwhile, the debate calmed down. Important single technologies from
the "hybrid package" will be gradually introduced for all vehicles, regardless of whether it is
diesel or petrol driven. Among others they are:
    • Recuperation
    • Automatic Start-Stop
    • Downsizing
    • Thermodynamics management
    • Decoupling of auxiliary drives

        In order to fulfil these requirements, the use of one or more e-machines in the drive train
(or enlarged alternator, starter), and a battery are required, resulting in a hybrid strain. This in
turn creates significant integration effort. VR integrated tools for laying flexible pipes help here,
Figure 6.




                                                349
                          Figure 6 - Development via Virtual Reality

        Whether one stays with the hybrid drive train or whether one comes back to a single
mode drive train is not yet finally answered. Increasing development activities in battery
technology makes it possible to appear that purely electric, battery feed vehicles with sufficient
range can be realized. If the questions about the battery for weight specific storage capacity,
safety and durability are not answered, a "range extender" will be off the essence. This role will
not take primary energy storage, but an energy converter. Short term an internal combustion
engine fired by bio fuel proposes to be the right choice. Medium term on can see a fuel cell with
the necessary energy via hydrogen use, Figure 7.

                                3.2 Low Price Vehicles (LPV)
     Under this umbrella term, two new vehicle classes are adopted:
   • In the developed markets, a new low-price segment opened below the current lower class
     (UKL). Dacia Logan opened this segment. In awakening mobility markets along with
     local requirements entirely new simplistic platforms come up. The first vehicle of this
     category is the just launched Tata Nano.
   • In both cases, it was necessary for the OEM, to refer to the mobility needs of the specific
     customer group.

                              3.2.1 LPV for mature mobility markets
         One of the success factors for the new low-cost entry-level class is a better understanding
of the user’s desires. With the Dacia Logan one has broken the coupling between vehicle size
and price, obliging that a cheap car has to be small. According to our investigations, there is no
positive correlation between customer preferences "small purchase price" and "small vehicle".
         LPV for mature markets have to comply with the high legal standards there in force, so
that in this area no savings can be realized.
         For the consistent approach of target costs, it is next to the tougher definition of the user
values of the specific user group, to define the non value items in order to eliminate them. The
necessary “definement” (opposite of refinement) refers especially to comfort functions and
technical characteristics. Thus, e.g. the suede covered trunk of the executive limousine with the
eyes of the next lower user profile can be seen as polluting burden. Double Seal levels, as well as
redundant adaptive heaters and more.
         OEM, which have been offering lower-class vehicles already are rather no favourites for
building up a new platform for the new LPV class in mature markets. Three potential cost
positions point to the second use of a expiring platform:
    • Double-use of a already realized development
    • Double-use of existing production equipment
    • Scaling in the component procurement
         Most producers combine the above mentioned cost potentials with the production of
vehicles in the emerging market for the mature markets in order to use the more favourable cost
structure.

                         3.2.2 LPV for Emerging Mobility Markets
       Quite unlike the previously described LPV for mature markets, it is for the Emerging
Markets.
       The objectives of such a product guide us almost inevitably to a new platform under the
following circumstances:
    • Extreme cost target
    • Use reduced legal requirements
    • Other user profile of the target group

        The aim of such a platform is the mass mobilization of a burgeoning mobility region. One
example is the Tata Nano, with a base price of 1 Lakh which is about € 1750.- wants to appeal to
a wide audience in the Indian market. The problem with such a development is that during the
development no safe customer preference profiles exist. In the first step it is not possible to
determine these, because the typical customer never previously owned a car, but at best a
scooter. It is here where by taking the Total Customer Integration (TCI) with its consistent use of
virtual methods the potential customer is consequently linked into in the very early product
development phase. By using virtual mock ups, loading operations, user habits, egress/ingress
have to be examined in depth, with the target to optimize. Unlike differentiated usage profiles of
premium vehicles, it provokes the creation of the broadest possible user profile. That the product
has to cope with minimum variabilities makes the task even more complicated. Thus, e.g. Tata

                                                 351
Nano has only minimal seat-adjustment functions, and still has to cope with most of the 5%
women and 95% men stature.

                                    4 Vehicle Homologation
        Homologation means legal approval of vehicles subject to the regulations valid in the
single country. The European Regulations typically contain a definition share of about 80% for
safety, 15% environmental and 5% other. Not only the car but also every specific automotive
component has to be admitted. Later changes on already homologated elements have to be
homologated again, if the modification is substantial.
        OEMs in Member states of the European community quite often have the opportunity to
homologate under the local state law or the Brussels’s community law.
        A state can refuse to homologate under Community legislation, but it cannot refuse to use
Community homologated vehicles on its territory.
        If there is no community law for a topic, the single state is free to release an own
regulation.
        The big advantage for the community homologation is the fact, that the car is
homologated for all member countries in one homologation step.
        Currently the following topics are in the focus of the legal authorities:
    • Pedestrian protection
    • Fuel consumption and emissions
    • Alternative power trains and fuels
    • Electronics: X-by-Wire and Car2Car communication
    • Vehicle stability control

                                5 Sumary and Outlook
      From simple to complex and back again - this cycle seems not even to stop in front of the
automotive industry, Figure 8.




                            Figure 8 - The Simple-Complex-Cycle




                                              352
                                            Figure 9

       On one hand the tip of complexity is still not reached with multicylindrical engines,
multi-gear lay-outs, but also the sustainability driven hybrid drive trains. On the other hand high
cost constraints until up to the middle class and Low Price Vehicle requirements of mature and
emerging markets ask for - what we would call by today's standards – a brutal simplification.
       The increased use of VR can give more certainty about decisions in the early product
design phase, especially when they are vehicles for new, unknown customer groups.
       Because certain is one thing: On both ends of the spectrum, it is more necessary for the
developer than ever, to have the customer in the middle of all his effort.
