First of all, I didn't just compare two different magazines and say which one was better. I made it clear that they were done by two different tests, and I was using the best acceleration times for each car. In fact, I gave both C&D and R&T's tests of the Mclaren F1 to show how varied their numbers were, to show that it's not entirely concrete. It just gives you a general sense, but not a decisive comparison. If the Diablo GT and Z06 were tested on the same day with the same driver, then that is another matter. I think I did misunderstand that. If the Z06 has better handeling than the Diablo GT, then I applaud them.; that would mean it also has better handeling than the Ferrari F40, Mclarnen F1 and Bugatti EB110, and that's quite an achievement. The Viper is another matter. Regarding speed above 60 mph, I can give you the Speed of the Diablo (6.0, SV, GT), but you would know that the acceleration of the Mclaren F1 beyond 60 mph is a total mess. I don't think there is much of a way to compare. But IF R&T and C&D are correct in their figures (11.6 and 11.5 seconds for the Mclaren), then: Mclaren F1: 0-60 mph: 3.2 seconds 0-100 mph: 7.5 seconds? 1/4 mile: 11.5 seconds @128 mph Diablo GT 0-60 mph: 3.7 seconds 0-100 mph: 8.0 seconds 1/4 mile: 11.8 seconds @ 124 mph Diablo 6.0 0-60 mph: 3.4 seconds 0-100 mph: 8.4 seconds 1/4 mile: 11.8 seconds @120.9 mph '98 &'99 Diablo SV 0-60 mph: 4.0 seconds 0-100 mph: 8.2 seconds 1/4 mile: 11.9 seconds @ 122 mph Those aren't just two different tests, those are compilations of different tests, and represent the best times of each car. The 6.0 has a lot of grip at the start, and the Mclaren F1 is very light, so they have the best 0-60 mph times. After that, the Diablo 6.0 is not as fast as any of them. But the Diablo GT doesn't seem to lose barely any more ground to the Mclaren F1 after 60 mph. The Diablo SV loses ground at the start, but eventually passes the Diablo 6.0.
