I am sorry, I don't get that jump - surely can't be right!!
The 997 Cargraphic GT3 465PS (1393kg) does 100-200 in 8.1s. That's a power to weight ratio of 0.33 PS/kg.
The 997.2 GT3 weights 1470kg with a driver and has 435PS, so a power to weight ratio of 0.30 PS/kg.
...and there is only 0.1s difference 100-200 with more weight and less horses????
Something is fishy here.
