Yes, I realized I should have used Z06 and GT3 instead of ZL1 1LE and GT-R NISMO for the ACR comparison. They’re more or less in the same category as the ACR.
The Z06 and GT3 have a low-slung supercar profile, whereas the ZL1 and GT-R fit the bill as GT-like “super” cars, akin to BMW’s M-range.
I will be concerning 5-60 and 60-100 like usual.
Automatic Z06:

Zero to 60 mph: 3.0 sec (not sure if rollout or not)
Zero to 100 mph: 6.8 sec
Rolling start, 5-60 mph: 3.2 sec
60-100=3.8; gap is 0.2 from 5-60. Probably, this car was tested with the rollout time included (perhaps 2.8 or 2.7 from 0-60 after rollout).
Manual Z06 (“convertible,” which really doesn’t make much difference since all the C7 coupes are targas, which are convertibles with manual input):
https://www.caranddriver.com/reviews/a15106326/2015-chevrolet-corvette-z06-convertible-manual-test-review/
Zero to 60 mph: 3.3 sec (note: 60 in first)
Zero to 100 mph: 7.3 sec
Rolling start, 5-60 mph: 3.9 sec
60-100=4.0 (3.6 if we cut just a bit short of the full 1st-gear launch), 5-60 gap from 0-60=(?)
On the surface, 0.6 sec—but then again, the car hit 60 in first. Think about 3.6-3.8 true 0-60. Still only around 0.2 true gap. Thankfully, the car stays below 90 in second (unlike the Viper).
GT3 RS:
https://www.caranddriver.com/reviews/a15099637/2016-porsche-911-gt3-rs-tested-on-the-street-and-track-review/
Zero to 60 mph: 3.0 sec
Zero to 100 mph: 6.8 sec
3.8 from 60-100; 5-60 is 3.9, which equates to a gap of 0.9 second.
Viper ACR:

I’ve used these results before:
0-60 in 3.3, 0-100 in 7.5.
5-60 is supposedly 4.4. (I think with much better driver input it could do around 3.9. Conditions must have been really rough for this car.)
Like the manual Z, this car hit 60 in first gear in this test. But it does reach less than 100 in second. Rule of thumb, 400 milliseconds removed per shift, especially when it comes to a high-horsepower car like this.
Theoretically, we’re seeing 3.7 0-60 and 7.1 0-100 (3.4 from 60-100, and even quicker in its sub-ACR trim levels) with better gearing; think 2.66 instead of 2.26 for 1st gear, and 1.30 for 2nd gear instead of 1.58, while removing 3rd gear (1.19) entirely, making this effectively a 5-speed car instead of a 6-speed.
Conclusion: the ACR should be faster in a straight-line than both of its competitors, but it is held back by gearing and intense levels of downforce.
