Corvette Acceleration Testing [Video]
#42
No worries dude I was curious where you got your 0-60 calculation from, because based on the mile markers he's flying. we can't really tell fully because it cuts out before he hits the 1/4 mile marker but based on 6.5-7s 1/8th mile times that should be less than 11s in the 1/4 mile! For reference, a ZR1 that did a 10.1 1/4 mile pass did the 1/8th in 6.53s
Of course not super accurate due to exact position... but not s l o w... ; )

I get 10.2 sec. to the cut just before the 1/4 mile marker. Another car length to 1/4? 10.5 sec ??
Note the driver releases the breaks and starts cold prior to start?
I am sure some one who can do a frame by frame can get a better idea for timing but as an estimate...not too shabby.
Anyone know a way to calculate a 0-60mph based on these vids?
I tried...and this is not my wheelhouse... at estimated 155 ft at around 4 sec. Not sure how this correlates if at all.
This is what I was saying about hitting 60 by the first yellow sign at around 120-130 feet.
Anyone have stats of Porsche or Ferrari 0-60 in feet ?

No, these are not full throttle launches. These are relatively slow, mild launches. Launching hard and running up thru the tach aggressively does not result in 3 shifts before 60 mph, all three of which executed in the lower half of the rpm range.
These launches are pretty mundane.

Sounds exactly like a DCT to me. (and I own one).
Looks like a coupe too. The cover does not flop inward as it would on the Vert. Plus I think I see the roof joint of a targa.
If testing with "lane assist" active then a signal is needed to deactivate it when changing lanes. Just a random hypothesis there.

I don't think anyone has been saying that lately.
All of the videos we have seen that have some audio indicate a V8.
BTW, I saw a lowered red 458 today down by Riverfront Park.
Do you know the owner?

These videos today are exciting!
If we assume most performance cars have an acceleration curve that spikes early and then gradually decays, we could guesstimate by looking at the VBOX graph of another car that did the quarter mile in about the same time.
Here is a car that did a 10.87 @ 125.26 mph. His time to 60 mph was 2.7 sec.

I am not saying that the shape of the acceleration curve for this car is the same as the C8. I don't know. This is ballpark at best.

All the stuff I read said Tremec including R&T today (21 June 2018)
A Corvette without a manual? It seems like an impossibility, but that's what our colleagues at Car and Driver believe. Instead, the mid-engine Corvette will use a seven-speed dual-clutch gearbox sourced from Tremec. Of its seven speeds, the top three are overdrives, and Tremec says it can handle 9000 rpm input speed and 664 lb-ft of torque.

Maybe wrong place to ask, but how does an ME stay cool with all the camouflage on the back? Air gets in the sides and front (?), but where does it exit?

I believe ZERV and SSM6Sedan(guy who said how many transmissions they ordered) also said that it was a TREMEC. ZERV even included this:
When you search “M1L Gamma Readiness Escalation”, a GM document about global supplier quality and the PPAP (Production Parts Approval Process) show up. http://www.iatfglobaloversight.org/w...6Oct2016-1.pdf
However, the transmission in the CADs look just like ZF’s PDK transmission. The transmission mounts are exactly the same.
I say it’s a TREMEC DCT, mostly because nobody with inside info has said anything about a ZF transmission.
