if the tested s600 is not again one of the modified cars for press people with 550+ hp, i suppose...

~ 4.6 for 0-100 km/h
~ 15.7 for 0-200 km/h
~ 22.8 for 1000m

that's all calculated (!) stuff, so it shouldn't be that wrong. the s600 will be somewhat slower than a 996 tt. don't worry folks, porsche is porsche...although the sl55 stays something irregular
