I stated this a while back but the video I saw has them do launch control and shift into 4th at what sounded like full throttle, was just over 7 seconds, . I had said then and will say again now, this, by what I have seen, isn't going to be impressive straight line. it may do great on a track with handling, aero and brakes but this isn't going to be a straight line monster by any stretch of the imagination unless they have a trick up their sleeves.
So, if the numbers in your quoted post are correct, you honestly believe it’ll be slower to 100mph than the C8 Stingray?
Straight line speed isn’t the main objective, I agree, but I’d hope everyone can agree it’ll still be significantly faster than the Stingray in this performance metric. .
By your chart shouldn't it be 8.42 - 1.08 = 7.34 sec? Also, doesn't the giant bog from 1 to 2 sec seem strange? I watched a few videos of the C8 Stingray and it doesn't seem to bog like that during launch mode. Maybe they were tuning the algorithms and it wasn't working right yet in the video you are analyzing?
Thank you for pointing that out, figured I had to be making an error somewhere. I hope you're right, and more than likely you are, because 7.3 isn't that impressive either.
In another place I saw 99 mph at 8600. That would mean a transfer gear of 1.65 versus 1.46 for the Z51 or about 13% steeper gears with a slightly taller tire. That would mean about 69 mph in second gear assuming no gear ratio changes other than the transfer gear. so 60 mph or 100 kph will occur in 2nd. And then end of the quarter mile should still be in 4th.
I used 1.66 transfer gear with 3.55 rearend gear for a 5.9 overall gear ratio, 4th is geared for the 1/4 it appears and 5th for the Ring straight though not the most efficient spread and hoping they’ve changed trans gears.
If you look at acceleration/ton which includes torque/weight/gearing
Of course those gears are guesses, but seems reasonable place to start.
I'll update the numbers once we know for sure.
<edit> Also note that for the acceleration numbers I am assuming 625HP and 480lb-ft of torque. The 480 is probably too high. Probably closer to 450. But because of the magic of gearing and RPM, it doesn't hurt the acceleration.

I used numbers that were very slightly different and got speeds within 1 MPH of your numbers through the first 4 gears. So it will be in that range. Math is math. What we don't know is if they changed the gear spacing any. Not sure there is a reason to add the cost. Maybe they would to make the 0-60 very slightly stronger.
I agree that straight line acceleration isn't the primary goal of this car. To me it's about FUN on the track. It's not about what some hot shoe can do with Cup2R's. If it's a turd in the acceleration department that will significantly affect the fun department. Glad I'm far enough down the list to get a second year car so I can see if it's actually worth six figures or not first.
I do. All the time. It's part of the reason I sold my C7
If true, you must be surrounded by some soft betas. Try that in my neck of the woods. And, the C7 was always a barely funded stopgap, so your bad for buying one in the first place.
Happy that you got a significantly less powerful car, with less expandability/mods, then a Twin Turbo would have provided ?????
Now, you'll be ridiculously overcharged for a completely new, more complicated, and unproven 4valve flat plane crank powerplant, that should have been the base engine for the $60k 2020 C8.
Now, all performance models will be significantly more expensive, with ZO6 buyers paying ZR1 money for forced induction, and ZR1 buyers paying Porsche 911 Turbo money for the Zora.
This is terrible news, unless you have more money than sense.
Based on posts, many here are have none of the latter.
