3.1 seconds and 10.3 seconds (0-100/0-200 kph, official claim) will be achieved always, under all driving conditions.

You are comparing the 997 Turbo S numbers with the current 991 Turbo/Turbo S. 

Speaking of your 991 Turbo vs. Turbo S comparison (35.x seconds vs. 29.x seconds), the 6 seconds gap. Your forget a couple of things here: 1. The Turbo S engine revs up to 7200 rpm (for a purpose, it helps to optimize the "shifting gap") and 2. The Turbo has a different boost mapping at speeds over 200 kph (the air blades on the Turbo S push more air, so the "proportional" boost is higher). Also I don't know if the 35.x seconds claim was with or without Sport Chrono active, keep that in mind too.

under all conditions ex. 35 degrees celsius 4 person on board plus luggage and some altitude above msl, nope. Test standards are not done under worst condition and heavy wight... I dont believe that.

i m am comparing the engine of the 997.2 turbo/S vers the 991 turbo/s engine and since you are saying that the new 991 turbo S is from 200-300kmh almost 5-6 secs faster than 991 turbo (up to 200 kmh the gap is bretty small) with only 40hp difference i do question that. specialy in those speed range 200-300kmh were almost all the power is needed to over come drag 40hp doent make a 5+ secs gap.

So if we stay with your numbers 0-300kmh under 30 secs, so 991 turbos 560 is about equal to the 997 gt2 rs with 620hp... or the mp4-12c with 625 hp..

 

I have the same question - 29 secs against 35 secs for 0-300 is too much isnt it?
