The key to affecting the development of tomorrow's mobility lies in
our readiness to challenge what is established and in the ability to
present new options. In order to meet these objectives, BMW Group
Design taps into the potential of the GINA principle (Geometry and
Functions In "N" Adaptions) which promotes innovative
thinking by allowing maximum freedom of crea-tivity. GINA produces
dramatically different solutions that affect the design and
functionality of future cars. The GINA Light Visionary Model is an
optical expression of selective, future-oriented concepts which
provide an example of the manner and extent of this transformation.
BMW Group Design is not just interested in answering the question of
how the car of the future will look but primarily wishes to explore
the creative freedom it has to offer. Both of these aspects are
affected by the requirements that future cars are expected to meet.
All ideas that the GINA Light Visionary Model presents are therefore
derived from the needs and demands of customers concerning the
aesthetic and functional characteristics of their car and their desire
to express individuality and lifestyle. The GINA Light Visionary Model
has an almost seamless outer skin, a flexible textile cover that
stretches across a moveable substructure. Individual functions are
only revealed if and when they are needed. With this model, BMW Group
Design initiates a fundamental discourse about the characteristics
that will affect the development of cars in future. It is therefore
fundamentally different from concept cars, which reflect what is
expected of them by implementing as many elements as possible in a
future production model. In contrast, the GINA Light Visionary Model
is a vision of future cars and serves as an object of research. The
seamless car body of the GINA Light Visionary Model. Putting its
visions of tomorrow's car into practice, BMW Group Design has
developed a two-seater roadster with the unique dynamic proportions
that are typical of its brand. The GINA Light Visionary Model takes
the sculptural design that has already been established by a number of
production cars to a new, unparalleled conclusion. The car's front and
sides, including the doors, create one single uninterrupted, seamless
whole that converges to form an optical as well as a structural unit.
In order to create this appearance, it was necessary to move beyond
all previous conceptions of car body configuration, design and
materials. Therefore, the GINA Light Visionary Model has dispensed
with the usual body elements found on production vehicles such as
front apron, bonnet, side panels, doors, wheel arches, roof, trunk lid
and rear deck. Instead, a new structure with a minimum amount of
components has taken their place. A special, highly durable and
extremely expansion-resistant fabric material stretches across a metal
structure. This new material offers designers a significantly higher
level of freedom of design and functionality. The body consists of
only four elements. The largest component extends from the front of
the vehicle to the edge of the windscreen and down the sides to the
rear edge of the doors. The large side panels start at the front where
the rocker panels emerge and run across the rear wheel arches into the
rear. The fourth component is the central rear deck element. An
innovation breaks new ground: car with a flexible outer skin. The
innovation of a flexible outer skin breaks new ground in automotive
engineering. This revolutionary solution opens up new design,
production and functionality potential. It has a major impact on the
interaction between driver and car and enhances it by offering a
variety of entirely new options. Some elements of the substructure are
moveable. The driver can move them by means of electro and
electro-hydraulic controls. This will also change the shape of the
outer skin, which can thus be adapted to suit the current situation,
the driver's requirements and can also enhance the car's functional
range. The most striking example of this is the headlight design. In
normal position, when the headlights are not active, i.e. when there
is no necessity to illuminate the road, they are hidden under the
special fabric cover. As soon as the driver turns on the lights, the
contour of the front end changes. Activated by the metal structure
that lies beneath it, the previously closed fabric cover opens to the
right and left of the BMW kidney grille and reveals the BMW double
head-lights. The rear and the rocker panels of the GINA Visionary
Model can also adapt both the shape and function to the driving
situation in hand. Both can change the shape of their outer skin to
meet the driver's requirement for particularly dynamic motoring. This
concept also takes into account a potential interaction with
aerodynamic requirements. The design of the rear element allows for
automatic lifting of the rear spoiler when a certain speed is reached,
thus creating extra downforce on the rear axle at higher speeds. Due
to the fact that the entire rear end, including the spoiler, is
covered by a single sheet of material that reaches as far as the rear
compartment of the interior, the homogeneous shape of the car's rear
will not be affected by changes to the spoiler position. The
mechanical system that moves the elements remains concealed. The turn
indicators and the taillights function without changes to the shape of
the outer skin. Their position, however, is only revealed upon
activation. The emitted light shines through the translucent fabric
cover, which is permeable to light but not transparent. The rocker
panels demonstrate the formal versatility of the GINA Light Visionary
Model with an equally impressive performance. The air duct can be
optimised if required. A corresponding movement of the metal structure
results in an adjustment of the rocker panel contour to allow for
better airflow. At the same time, an additional protruding rocker
panel line emerges. The aerodynamic optimization and the length of the
line can be infinitely adapted to the driving situation at hand.
Special fabric cover ensures accurate reproduction of material folds.
The fact that the body surface is designed by means of a flexible
fabric cover that stretches across a metal substructure means that the
materials used must meet exacting requirements. Industrially produced
hybrid fabric made from a stabilizing mesh netting support and an
outer layer that is both water-repellent and resistant to high and low
temperatures is suitable for this application. Another essential
material property is a maximum level of dimensional stability. It must
remain dimensionally stable irrespective of the temperature and air
humidity it is exposed to even after severe and constant expansion.
The dimen-sional stability helps retain the cover's surface tension
for a long period of time. The movement of individual body elements
creates accurately reproducible folds in the material. In its choice
of material BMW Group Design was inspired by exterior and interior
architecture. The expertise of seat pattern designers working for BMW
Group Interior Design was successfully applied in order to cut the
fabric webbing to size with maximum precision, determine the strategic
position of attachment points and stretch the material. As a result,
the surfaces are remarkably well balanced and due to the steady
tension that is retained between any two clearly defined points, the
lines are extremely accurate. The special fabric is supported by a
metal wire structure. At specific points, the high-strength metal is
enhanced by carbon struts with a higher flexibility. They are used
predominantly for round, moving contours with a particularly narrow
radius. The use of large fabric areas and the possibility of changing
the surface contours by moving individual parts of the metal mesh that
lies beneath it create a new relationship between form and function.
If additional cooling air is required, the BMW kidney grille at the
front of the vehicle can be opened. Because the overall surface of the
special fabric covering remains unchanged, the contraction at the
front of the vehicle, which is necessary for functional reasons, has
to be compensated for by extra tension in other areas. The result is
an optically attractive interaction between various body parts that
introduces a new dimen-sion to sculptural design. The widening of the
kidney grille openings is activated by a movement of the metal mesh in
the front area of the side panels. This creates more tension, which
becomes visible by the emergence of an additional character line. The
development of this new contour tenses the front of the vehicle: the
kidney grille opens up. Innovative body structure introduces new
functional dimensions. The high-precision fit of the material to the
metal mesh also allows surface changes without slackening the tension.
In this case, opening of the surface by moving the respective steel
mesh struts creates precisely defined folds in the material. The GINA
Light Visionary Model uses this option to display a function that
corresponds to the opening of the hood in conventional vehicles. The
material opens at the centre of the engine cover and can be folded to
the far right and left along an opening line that is approximately 0.5
meters long, to allow the driver or mechanic access to the service
points in the engine. The filler caps of the engine oil, cooling and
wiper water tanks are now open for servicing. Opening and closing is
similar to the mechanism on a doctor's traditional medical bag, where
clip-lock fasteners are held together in the middle by a rail. The
effect of the accurate surface material draping is even more
impressive when the doors are opened. They swing both outwards and
upwards. The high number of attachment points for the fabric cover
positioned at the front of the car as well as at rear door edges
creates a clearly defined and perfectly reproducible bulk of material.
The draping is confined to the area between the front door edge and
the side panel. Once the doors are closed, the folds in material
disappear completely, leaving a perfectly smooth, stretched material
surface. The interior: discourse between driver and vehicle. In the
interior, variability, form and function are united in an inseparable
connec-tion. Whenever selected functions are accessed, the driver also
changes the appearance of individual car elements. Again, the car's
variability is adapted to suit the driver's needs. This creates a
close interaction between driver and car in various different
situations. When the car is parked, the steering wheel and the round
instruments - rev counter, speedometer and fuel gauge, which are
vertically arranged on the centre console, are in idle position. This
provides the driver with maximum comfort upon entering the car.
Likewise, the seat only assumes its optimised functional position and
shape if and when the driver sits down on it. At that point, the
headrest, previously firmly integrated into the seat's backrest, rises
up automatically. At the same time, the steering wheel moves towards
the driver and the instrument panel moves in the same direction. The
information on the best driver-specific position of both steering
column and seat is stored in the transducer. The engine is started
simply by pushing the start/stop button. The smooth transition of
interior and exterior that is typical of BMW convertibles is
reinterpreted by the GINA Light Visionary Model. The fabric that
covers the rear deck runs into the interior and stretches across the
driver and front passenger seats. The same material is also used for
the surface design of the door trim and armrests. The shift lever in
the centre console protrudes from tightly stretched textile bellows.
Driver and front seat passenger look out through a steeply inclined
windscreen with the inside rear view mirror integrated into its frame.
The side view mirrors are connected to the window frame. A narrow
vertical dividing bar located at the center of the windscreen harks
back to the typical windscreen division of traditional roadsters.
Innovative thinking put into practice: the GINA Light Visionary Model.
With the GINA Light Visionary Model, BMW Group Design focuses on a
wide variety of issues that will determine the future conception of
mobility. It demonstrates the results of intense research into design,
functionality, material and production. All ideas that have been put
into practice in the GINA Light Visionary Model are derived from the
same motivation: to challenge conventional and previously pursued
solutions. The quest for alternative options has generated a wide
variety of different requirements that potential solutions are
expected to meet. The main focus is on providing general versatility
and catering to customer requirements with sophisticated solutions. In
accordance with the GINA principle, every functionality enhancement
helps to create an emotional bond between the driver and their car.
The new solutions also allow for the option of fast, flexible and
cost-efficient production. Every innovation demonstrated by the GINA
Light Visionary Model also contributes to a clearly optimised resource
management. As the quest for sustainability is one of the central
issues of the GINA philosophy, new materials and manufacturing
processes are expected to consume less resources and energy than
previous solutions. Accordingly, the infrastructure used for
manufacturing cars that are built in compliance with the GINA
principle, has also changed. The manufacturing process requires fewer
model-specific tools, and more highly-qualified skilled specialists.
In all the areas referred to above, the GINA Light Visionary Model has
provided inspiration for more intense research into ideas conceived as
a result of maximum creative freedom. Emotional appeal of roadster
models and visionary prospect of future cars. The solutions conceived
as part of this philosophy are not considered sepa- rately, but have
been pooled in an integrating vision - a vision that is expressed in
the context of an outstanding, fascinating car. The basic features of
a roadster with its eight-cylinder combustion engine below a stretched
front that applies motive power to the rear wheels in order to move
the car along the road defines this context. The synthesis of
elementary visions and sheer driving pleasure expressed by the
appearance of the GINA Light Visionary Model has a particu-larly
striking emotional impact. Only the particular appearance of a
fascinating car with its authentic design that creates a natural
aesthetic look can bring to light the significance of the presented
innovations. The GINA Light Visionary Model builds a bridge between
vision and reality by presenting a number of features with a striking
similarity with those found on production vehicles. The Roadster rests
on 20" alloy wheels in a cross-spoke design with a matt silver
finish. The car body is comprised of an exceptionally light aluminum
space frame. Two double tailpipes for the rear exhaust system, a third
brake light integrated into the height-adjustable rear spoiler, an air
splitter at the front and a rear-end diffuser in a carbon design also
meet the standards of a production vehicle. Nevertheless, the GINA
Light Visionary Model retains its character as an object of research.
It demonstrates the innovative force of BMW Group Design and its
ability to challenge what is established, to find new solutions and to
interpret these in the context of the car of the future at a high
aesthetic level. This car is the logical continuation of the GINA
principle in action. The GINA principle has already led to a variety
of innovative concepts and has production vehicles in ways that are
completely new and unprecedented by any other car manufacturer. BMW
Group Design uses concept cars such as the BMW concept car CS1 of 2002
as a step on the way towards putting a particular vision into
practice. The CS1 was the first to present features such as the basic
principle of the innovative control system - the BMW iDrive.
Independently from all other innovative features shown by this concept
car, the iDrive has become a series production feature. Similarly, the
GINA principle gave rise to an innovative manufacturing method that
allows the manufacturers to decorate outer skin components that have
been preformed by conventional methods with indi-vidually configured,
high-precision contour lines prior to their reintegration into the
manufacturing process. The Rapid Manufacturing method utilized for
this process was first used during the production of hoods for the BMW
Z4 M Roadster and the BMW Z4 M Coupé. In these models, the
finished hood has received two distinctive contour lines prior to
painting. These are not produced by a pressing tool but embossed into
the metal with pin-point precision by a robot-guided steel pin. Both
examples illustrate the challenging route from a vision to a concept
and to final series production that is not always straight and direct.
With the GINA Light Visionary Model, BMW Group Design shows where this
route begins. Not all innovations shown by the GINA Light Visionary
Model will pro-ceed to the next stages. In its entirety, however, the
visionary look into the future shows the extent to which the BMW Group
employs creative potential in its endeavor to respond to the
challenges of tomorrow's mobility.
