Tiptronic S.
There was a time when the sports-
car buyer was forced to choose
between the control of driver-
executed gearshifts and the
ease of automatic shifting.
Porsche changed all that with
the introduction of Tiptronic, a
highly sophisticated automatic
transmission with a manual-
shifting option.
The five-speed Tiptronic S, the
latest advance of this technology,
is now available as an option on
the 911 Turbo. Far from
compromising performance,
its lightning-quick gearshifts
actually reduce sprint times
compared to that of the standard
six-speed gearbox. Tiptronic S in
the Coupe shaves 0.3 seconds in
the sprint from 0 to 60 mph, and
0.3 seconds from 0 to 124 mph.
The Tiptronic S in the Cabriolet
reduces the 0–60 mph time by 0.3
seconds. The 0–124 mph time is
reduced by 0.2 seconds.
