The evidence is in the fact that the Z06 does 198 MPH (drag limited) and the 911 is gear limited at 185 mph. I am not sure of the exact # of car lengths, but it is not as small as YOU think. 1.5s is quite a bit at those speeds and I am assuming the difference gets wider based on te London Speed test. At 150 MPH, the cars are moving ~220 ft per second, so take tht for what it is worth. This is NOT advanced Pyhsics here. It's D = RT. In other words, Distance = Rate * Time.

There are those here who question the supposed "bashing" of their marque by Corvette fans. But if the Z06 had been defeated by a base Boxster in those tests what level of crowing would be appropriate from Boxster fans? Price wise whither Porsche? Corvette fans have earned their right to crow. And from a price standpoint some hard and honest questions need to be asked by even Porsche’s staunchest defenders.
For the Ferrari the destruction was shocking in its violence. The 0-150 mph gap staggers the mind. I do wonder though why they used old acceleration numbers. Did the Ferrari break or did Ferrari step in as per normal and forbid acceleration testing? In any event, having long since ceded acceleration prowess to the Corvette, Ferrari’s supporters have resorted to claiming that the Vette is a one-trick pony that would fall flat on a track. The implied car-length gap over the Ferrari on this small track was 17. There is nothing small about that. As someone here rightly observed, if the Z06 did this on a small track a big track will be worse. Much worse.
So now supporters from both competing camps are reduced to making excuses for the Z06’s tested opponents. These excuses run the gamut from the usual desperate it-costs-more-therefore-it-is-and-you-wouldn’t-understand (haughty and pretentious sniff) from those whose lives are such that they easily see the necessity of a social crutch and so on and so on. All these excuses and untenable subterfuges boil down to a single undeniable fact. By any objective measure of performance the Z06’s expected worthy performance opponents were emphatically rubbed out. It is going to take a lot deeper reach into the opposition’s respective triple-digit cost arsenals to retaliate. For Porsche, the aforementioned upcoming GT2 while for Ferrari I cannot imagine. The 599 will not be any more nimble than the F430 though it should undoubtedly be better in a straight line.
So why the rankings in Car and Driver? It’s actually painfully simple. Car and Driver runs a business. That business is dependent on generating attention grabbing headlines at all costs. Italian marques do that more than anyone else because they are gratuitously expensive and, as such, relatively rare. To tell the truth about the way the cars should have been ranked as a totality, not just on performance, would have likely meant that Ferrari and possibly Porsche would be less inclined to submit cars for further comparison testing. Ferrari for one is famous for having done this before. When nobody else will compete then there will be fewer headline grabbers as everyone will already know the likely outcome and the marketing schemes of the European marques will unravel. For another example of the sort of gerrymandering businesses do when this sort of situation arises simply review the events in the GT1 class at the recent ALMS "race" in Utah.
On road and on track the Corvette’s dominance is now essentially complete. From a heritage, technology and performance standpoint there are really no more practical worlds left to conquer and nothing left to prove.
Well done GM. Well done.

For example the relative 1/4 mile (fixed point) numbers for the Z06 (11.7 @ 123 mph) to F430 (12.5 @ 116mph).
Figure the time gap between the two cars: 12.5 - 11.7 = 0.8 secs.
Then determine the rate at which the Z06 was covering ground when it blew by that marker: 123 mph = 179.58 ft./sec.
Multiply that by the gap of 0.8 secs: = 143.66 ft.
Convert that distance to inches by multiplying by 12: 1,723.96 inches.
Then divide by the known length of the Z06 (175.6 inches): = 9.81 car lengths.
Did I miss anything beyond the minor assumption that all acceleration ceased at the 1/4 mile? If not, what did I win?
Like Andi said, if the 150 mph gap was at a fixed point Frank's right.

There is a big difference between "time to distance" measurements (quater mile) and "time to speed" measurements.

Apparently, they haven't studied calculus and understand rates of change.

You don't KID YOURSELF. I said you can't know the exact number without seeing the exact acceleartion data. Unfortunately we don't have it so we can speculate all we want. I don't need to learn more applied physics because I know it. As far as the gearing an torque multiplication factor, I have not gone through the math but I suspect it has more of an effect than you give it credit for. A better measure of the cars performance at higher speed would be to pick a distance and see what the elapsed time is (say like a 1/2 mile) and see what the elapsed time is...just like we do in the quarter.

Performance per dollar the Z06 simply cannot be beat and if you're only objective is to have the faster car it is the surefire winner, but money no object really tell me which car you'd rather have (having driven both)....

Z. The 0-100 time in this test, is slower than other tests performed. The driver may not have had much Z time under his belt.

Stunning performance from the Z. I would have expected a much closer fight, although to be fair, shame on C&D for using previous accel numbers for the Ferrari rather than same day, same conditions. The F430 has been in the high 11s with a trap of around 120 mph in some tests, those where the F1 tranny was used to its full advantage.
There's no question which order I would buy these in a perfect world (Ferrari, Porsche, then Z06) but the Z06 puts TRUE supercar performance in the hands of a successful (but not necessarily well off) American, in a damn sexy package, which deserves kudos.

Bone stock (including factory ECU tune).
0-100, ~7.8 sec.
Magazines give you real 1/4 mile trap speeds, dragstrips average it over the last 60 feet, which hurts your trap by a mph or two..

Did anyone notice that 2 of their rolling acceleration tests are completely wrong?
Notice 0-100 for the Z06 is 8.3 seconds
and yet, somehow 30-50 is 9.1 seconds !!!???? --- i think my moms van does 30-50 quicker
and also 50-70 is 9.0 seconds.
all of that while 0-100 is only 8.3...............

With the Ferrari the disparity is likely the result of the F1 system's software refusing to go to top gear at such low speed. Not sure what the Porsche's excuse is. If it was a tip then the plot thins but if not I am not certain.
