The benefits of Tiptronic S are
particularly apparent when
exploring the car's potential. In
automatic mode, the rapid
gearshift action ensures excellent
agility under power. The
immediacy of response, with
virtually no interruption in
drive, is comparable with a Porsche
manual gearbox. In terms of ac-
celeration, it is even better, being

If the car is driven more assertively,
the system automatically selects
the 'Sport' gearshift pattern, i.e.,
there is no need to use a kick-

automatic systems, Tiptronic S
does not shift up when the throttle
is released, enabling optimum
acceleration when exiting a corner
with no loss of stability due
to changes in load. Mid-corner
gearshifts are also prevented,
thereby enhancing stability and
safety. Under heavy braking,
the system shifts down, using
engine braking to slow the car.
