I agree. The DCT + launch control should remove the driver variable (apart from his/her weight) in 0-60 or 1/4 mile times.

According to the data, both cars are right there by the time they cross the 1/4 mile. There are no other indications. No difference between the C7 Z51 and base model it appears. The Z51 should have a slight edge for what it's worth. So both cars are at 11.3@121. That's very quick. Now once the boys get a hold of this car on a well prepped track, possibly lower 11's or high 10's

The numbers are solid. But we have somewhat known this since the reveal, with the DCT and more technology than ever in a mid engine car that can put the power down better this car is going to be a crazy amount of performance for the price.
I can't even imagine what the C8 Z06 and Grandsport will be able to pull off.

I find those times very interesting and the comments that GM is overly zealous with their performance numbers is simply not true. I recall the times stated for the C5, the C5 ZO6, the C6, the C6 with the LS3, the C6 ZO6 and ZR1 and later the C7 base, Z51, ZO6 all were conservative at the time and many drivers exceeded those numbers with regularity. As to the car mags never making those times you have to realize 2 things. They test those cars over a relatively short period of time and really never get to know exactly how to get the best times and they do an average for their publications. It's all about "seat time" and anyone owning a car knows what I'm talking about. Just go on the "Fast List" for any of these cars and check out the "Stock" times. Finally so many of the car mags also tested M7's which like it or not are slower than the autos. I would predict that these C8's will show up at the tracks and drag strips all around the country and they'll live up to those figures. Just saying!

Even with absolutely perfect shifts, the Z06 has more traction concerns, there is a let off of the throttle, etc. I bet to 100mph, a C8 will get the jump on a MT Z06 even with a great driver. Now, that jump won't last all that long because by the 1/4 mile, the Z06 is trapping a higher speed and pulling away. R&T tested a MT Z06 at 7.6s to 100mph. Exactly the same as GM's number for the C8.
Traction, DCT, gearing all play an important role in acceleration to 100mph... after that, the C8 doesn't stand a chance being down 150HP.

If it does or doesn't beat a Z06 it will be close enough which helps those on the fence thinking for the same price for a c8 I can get a Z06. Even though I have given them some sh't about options and NPP being spinless, they have been able to pull off a nice upgrade.

Weak braking and lateral G specs?
Anyone else notice these specs Would have thought braking would be closer to 100 ft or less and lateral g to be over 1 g. Probably reading too much into unofficial specs but has me wondering if the non Z models will be more of luxury touring piece than a sharp handling instrument?

that the Z51 has 6% more thrust (differential ratio ratio) AND
that the Z51 car takes 2 shifts to 60 MPH while the non Z51 takes only 1
We could postulate that non Z51 should take 2.95*1.06 = 3.12 - 0.1 = 3.02 seconds 0-60
(the -0.1 is the missing shift)
This lines up nicely with the newly presented data.
However, the non Z51 will be slower (by that 0.1) to 65 MPH due to the additional shift.

The old school engine still consume a lot of fuel so that’s why they are using long gears to improve fuel economy!
What I hate about C7 that’s you will be killed in street races by cars 100 hp less than you once you are in super long 5th gear I really hate it
I think the same story will happen to the C8
0-60 time is nothing

Bragging rights are different than the reality: 90% of you guys will never find the tenth between the base and the Z51 (or the C7 Z06) - or even bother to go looking for it. Screen racing (today’s version of bench racing) is always fun, but the reality is the C8 is a remarkable achievement and the fast guys will soon learn its tricks - and the C7 Z06 being faster discussion will never come up again.

Nope. The guys saying this was going to be a high 11's car and would barely be quicker than the C7 Z51 let alone challenge a C7 Z06 to 100mph from a standing standing start.

If that turned out to not be true, the car would be a flop and GM isn’t going to let that happen. If the C8 was a poor performer and GM said “just wait for the Z06” they would lose way too much momentum with this car. They aren’t that stupid.
This car will perform exceptionally well and represent the Corvette badge very well.
