ALFA DUAL STAGE VALVE
SUSPENSION (DSV)
(where provided)
The electronic suspensions control
system of the car is the result of a
sophisticated elaboration of the various
board sensors, aimed at optimising the
performance of the car.
The system offers the driver the
possibility of selecting two different
suspension damping setups via the
suspension button. A special two-stage
valve inside each shock absorber,
electronically controlled by a control
unit, allows the damper setting to be
changed between two modes, a soft
mode to improve ride comfort and a
hard mode to favour handling and road
holding.
The driver can choose, even while driving,
(only in "d" or "ESC OFF" mode), between
two types of suspension calibration: a
more sporty or a more comfortable one.

absorber calibration which favours
driving comfort.
