Laptimes are incorrect. The 997TT times are (courtesy of Art here
7:54 by Horst from Sportauto
7:49 by Walter from Porsche
The 7:40 was a factory estimate from Porsche reported in Motortrend.
If they truly wanted the most "apples to apples" comparison they should have used factory driver time vs. factory driver time. That is 7:38 vs. 7:49. All that being said I think everyone knows my skepticism on the 7:38 time. Of course we all saw it but what does it really mean.
