The EOS 2006

The self-study programme shows the design and
function of new developments.
The contents will not be updated.
For current testing, adjustment and repair
instructions,
refer to the relevant service literature.
The Volkswagen Eos combines the characteristic flair
of a cabriolet with the emotional design of a coupé.
It is thus aimed at two different groups of buyers and
builds on the tradition of cabriolet production at
Volkswagen.
This very successful tradition started in 1949 with the
first Beetle Cabriolet and continued in 1979 with the
Golf Cabriolet and in 2003 with the New Beetle
Cabriolet.
Unlike its predecessors, the Eos is not derived from
another model, it is an independent development that
unites the characteristics of different vehicle types and
heads in a totally new direction in terms of roof
technology.
Together with the values of quality, comfort, safety
and engines, the Eos has a rounded, promising
vehicle concept that sets new standards among its
rivals.

In Brief
The Eos is named after the Greek goddess of the dawn, who was the daughter of the Titans Hyperion and Theia.
According to legend, the Titans, the oldest race of Greek deities, are the children of the first gods Gaia and Uranus,
who originate from chaos.
Eos is the sister of the sun god Helios and the moon goddess Selene.
Eos rises out of the Oceanus every morning and travels ahead of Helios in his chariot as he rides across the sky to
herald the new day.
Homer praises her beauty and her grace and describes her as a wonderful, beautiful and curly-haired goddess.
The Eos from Volkswagen combines the everyday and all-year round suitability of a coupé with the classic open-
top driving characteristics of cabriolets without their disadvantages like, for example, high noise level.
The Eos is built at the Auto Europa plant in Palmela, Portugal.

Body
A body with a high static and dynamic rigidity is the
requirement for good vibration behaviour and
excellent driving properties.
This is achieved by using high, higher and highest-
strength sheet qualities as well as THERMOFORMED
SHEETS in conjunction with modern joining methods
like laser welding and structural adhesive joints. The
use of thermoformed sheets, in particular, has
increased the stability of the body without making it
heavier.
The following components are made from highest-
strength sheets:
- Inner A-pillar
-Seatconsoles
- Sills
- Rear longitudinal members
Highest-strength tubes are fitted in the upper area of
the doors and under the rear seat bench.
Thermoformed sheets are used:
- in the front bumper cross-members
- in the A-pillar reinforcements and in the
front windscreen frame
- in the door reinforcements

Special body-in-white measures
To also guarantee the excellent vibration behaviour of
the cabriolet-coupé when the roof is open, extensive
reinforcements were made to the body-in-white in
addition to the use of the described sheet qualities.
In addition to the higher sills, the cross members on
the upper edges of the doors and the reinforcement
of the rear panel, they are mainly in the introduction
of a supporting front underbody capsule made from
aluminium and diagonal struts mounted in the rear
area.
The underbody capsule and diagonal struts are
bolted. The underbody capsule connects the front
subframe to the longitudinal members.
Together with the diagonal struts, this creates an
additional reinforcing level and thus increases the
torsional rigidity of the whole body.

Pedestrian protection
cross member
Front-end frame
In the body development, greater focus has been
placed on pedestrian protection in addition to
occupant protection. The aim is to reduce the risk of
injury to pedestrians and cyclists by means of
constructive measures.
The Eos has a complete concept for the front end
that comprises the following measures:
- Sufficient spacing from hard engine compartment
parts under the bonnet
- Optimisation of hinges and interior sheets on the
bonnet
- Lower risk of leg injuries
Reduction of leg injuries
The Eos has an additional cross member for
pedestrian protection that has a deformation element
made from foam.
The deformation element absorbs a large proportion
of the energy in a collision so that the risk of severe
leg injuries is reduced.
In terms of car crash safety, we distinguish between
three different load levels that have to absorb the
forces in an accident.
The upper load level is formed by the roof, the middle
load level is the side structure of the vehicle and the
lower load level is the vehicle floor structure. On
cabriolets, the forces caused by a collision mainly
need to be absorbed by the centre and lower load
level because the roof construction is, to a great
extent, not part of the vehicle statics.
