RC:

From 0-100 kph and from 0-200 kph, the 997 Turbo S will always beat the GT2

Things look different at speeds over 250 kph.

From 0-100 kph, there aren't many cars on this planet which can beat the 997 Turbo or Turbo S.

 

997TT/TTS with PDK has quite an advantage in a launch from 0kph. My expectation would be that the TT/TTS does not have an advantage if accelerated from an initial speed of >50kph or so. There should be then another advantage for the TT/TTS at up-shifts at higher speeds (>150kph) as the PDK shifts very quickly and the GT2 suffers from adverse aerodynamic effects while the gear is being changed. The GT2 will benefit when the power can work without interruptions from manual gear changes Smiley
