Rain sensor* Integrated rear suspension
The rain sensor controls windshield
wiper operation, depending on how wet
the windshield is.
Infrared light is carried along the sur-
face of the windshield in an optical con-
ductor in such a manner that it is re-
flected completely when the windshield
is dry. The quantity of reflected light is
measured.
If the window is covered with beads of
water, the amount of light that is re-
flected is decreased since the infrared
light at the surface of the windshield
can then escape. The quantity of re-
flected light is thus a means of gauging
the degree of wetness on the wind-
shield.

When the system is set to the "Intermit-
tent" wiper speed, the wipers react im-
mediately — if water is splashed onto
the windshield by vehicles traveling
ahead of you, for example. As a result,
the rain sensor provides a contribution
to driving safety and comfort.
This axle is based on the same multi-
link principle as that in series-7 vehi-
cles. The axle's kinematics and elastic
kinematics are critical for wheel control
— a significant prerequisite for achieving
the objective of exceptional onroad
handling characteristics with this vehi-
cle concept.
In order to reduce unsprung mass, the
wheel carriers and the swing arm are
made of aluminum.
For an outstanding quality in acoustics
and vehicle oscillation characteristics,
the differential is isolated with double
elasticity through a chassis sub-frame
toward the vehicle body.
