I'm resurrecting this thread in light of the discussion about the MK2 997TT.  Has anyone noticed something out of place?  Take a look at the 80-120 km/h run in 5th gear.  Gear ratio for the previous review of the MK1 997TT is identical, clearly different for MK2.  We find the following:
 

MK1 997TT 80-120 km/h 5th gear - 3.7 seconds

MK2 997TT 80-120 km/h 5th gear - 3.8 seconds

MK1 997TT Ruf 600 80-120 km/h 5th gear - 4.4 seconds

 

Testing conditions unclear...first two numbers from AMS, Ruf 600 from Auto Bild...can testing leave you with a huge 0.7 second difference?  Any thoughts?
