Improvements to the Tiptronic S transmission in the latest 911 Turbo contribute
to the performance gains by allowing an earlier ramp-up of boost pressure when
‘brake-torquing’ the transmission, and new tuning lets more torque accumulate
while the brake pedal is held. Other improvements reduce the time required for
the transmission to react to driver inputs, and produce quicker shifts.
If launched appropriately, a 911 Turbo equipped with Tiptronic S is essentially
“pre-tensioned” at the starting line, and during acceleration runs,
power-interruptions are reduced in comparison to the 6-speed manual
transmission. Aiding acceleration, when paired with Tiptronic S, the
all-wheel-drive system with PTM can deliver a nearly uninterrupted flow of
torque to all four wheels.
The optimized interaction between the new all-wheel-drive system, Porsche
Traction Management (PTM), Tiptronic S five-speed automatic transmission, and
Tiptronic-specific calibration of the engine management controls and associated
variable turbine geometry (VTG) system, allows the new 911 Turbo with Tiptronic
S to accelerate slightly quicker than models equipped with the manual 6-speed
transmission.
In terms of providing performance to our customers, the Tiptronic S transmission
has made the prodigious abilities of the 911 Turbo more accessible to a wider
range of customers. In its evolution, the Tiptronic S now provides certain areas
of strength in relation to the 6-speed manual, particularly in standing start
acceleration numbers, an area of quantified performance that grows more
challenging as peak horsepower levels continue to escalate.
