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, 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.
