I'm not saying they were bad, but perhaps less than ideal i.e. higher temperatures, different surface, different driver, etc... Whatever the reason, this test had some of the slower numbers I've seen (except for the ridiculously slow Quattroroute/road an track times). For exmaple, Car and Driver acheived 0-60 in 3.4, 0-100 in 7.8. Most mags have 0-100kph times in 3.6 or less as well as 0-160 in 8 flat or less. I am not surprised that the 997s has an identical slalom time, its lighter and has basically the same suspension set up. As for track times, unless they are all done on the same day with the same driver they must be taken with a grain of salt. Having said that I do beleive the Z06 is faster around most tracks. I doubt this weighs on the minds of 997tt owners. On a real road I doubt there are a handful of cars that could keep pace with a properly driven turbo.
