From the wheel movement and car movements the ZR1 looks to be far more stable and composed than both the Zonda and GTR (low and high speed). I guess thats proof that the much hyped about Magnaride suspension works. Even with the headwind its also interesting to note that the 638hp ZR1 was only able to reach 179mph on the long straight, whereas the 480hp GTR reached 180mph.
At start of straightaway:
ZR1: 6.36
GTR: 6.48 Difference= 12 seconds
To the end of the straight where the bridge crosses
Times:
ZR1: 7.05
GTR: 7.18
Time to run back stretch:
ZR1: 29 seconds (ZR1 reaches near 180mph and holds back)
GTR: 30 seconds
I personally think it is LUDICROUS to think the ZR1 could only put 1 second on the GTR through this contest of flat out acceleration EVEN if the GTR had carried more speed into the straight. Hell, even a "measly" 505HP Z06 has been shown to put atleast that much distance on a GTR from 0-120mph.
It looks like the GTR was doctored with A LOT more boost even if the tires weren't doctored.
