Wow. I am not surprised. If there is one thing I have learned driving my friend's 700 hp big block Superformance Cobra, traction is everything. There is no such thing as "floor it and go" in a 700 hp Cobra until you are going at least 100 mph, and flooring it at 100 mph in 3rd at high rpms in that car can sometimes result in wheelspin as well 
.
My guess is that 430 hp in a 2,500 lb car like that AC MkVI is an almost perfect balance of power/weight/traction and is able to put all of its power down without much wheelspin through the first two or three gears. The ZR1 is not able to use full throttle power until at least mid way through 3rd, which in that car is close to 100 mph
Put some slicks on the ZR1 and you have an entirely different race.

I probably have more passes then 95% of this board. 700+ to date on 5 different cars. A car with big power, even on street tires can be launched much better then that. Get the rev's up, and slip the clutch. I've driven 700 rwhp Z06's. It can be done with talent.

I agree with you about the poor launch of the ZR1 in the video. It does take a combination of talent and practice with a particular car to understand the nuances of its power delivery and how much clutch slippage, throttle, etc can be applied for optimum acceleration. You have to admit, launching 638 hp (like the ZR1) on stock tires (not properly warmed up drag radials) is really tricky and can easily result in wheelspin. My guess is they launched the ZR1 in this video with the TC on, which in most cars seems to result in slower times off the line.
It should not surprise anyone that a British show, which are typcially notoriously biased against American cars, would conduct this race in a way to make the British car look better.
Simple fact. ZR1 > AC MkVI lets do one more take with me behind the wheel of the ZR1

Who said anything about spinning the tires? Not I.

That launch looks to me like it was done with the TC on, which is slower then a good driver not using it.

the guy in the ZR1 needs to turn it off and re race
