What are your predictions for 0-60, 1/4 mile and trap speed?

assuming 460 hp LT1 with dct

Stingray23

Well, it better have more then those numbers even for a base car.
Heres what I'm hoping we get:
525hp 500trq w/DCT
3,250lb loaded
0-60- 3.4sec
1/4- 11.4@124

Woule be cool but they've got to leave some room for the hipo versions...

I'm thinking 0-60 in 3.5 and 1/4 mile in 11.6 @ 123

In todays performance world, 525 is perfect for an entry level corvette. Anything less is not enough.

Before the c7 reveal everyone thought the base would be close to 500 hp (from 436) however it only increased by 24 hp but still sold great.

The ME should be able to put the power down better regardless

This is an interesting mental/technical exercise- assuming the same exact motor in a front engine C7 versus a rear engine C8, how much would that affect the following performance areas given that the C7 front engine already has a perfect 50/50 weight distribution and is already a mid-engined car (just front mid engine versus rear mid-engine):

- Road course lap times
- Skidpad numbers
- 0 to 60
- 1/4 mile

I'm trying to determine how much advantage a rear mid engine car has compared to a front mid-engine car, assuming an apples-to-apples comparison (ie. same motor).

Well, going to move about 8% of the weight to the rear. So from an acceleration perspective should improve given the weight doesnt go up. I'm not track day regular but I have done a few of the drive exotics deals and from the track a mid car is alot different than FE. Corvette was alot easier into a corner with the weight and wide tires on entry, had to be easier on exit, the ME's were sorta the opposite, drive out of the corner was much easier. Like I said, these deals get ya a chance, in my case, to drive cars I could not have and the experience is limited, which is good cause I'm a hack! One of the best gifts my wife has given me though, ton of fun. Lol

In my opinion it's not going to get to 525... its such a revolutionary change they don't need to for attraction.

Every other recent model change had an increase in HP in the 30-ish range or so. I think they go with 500 or 505 hp.

With DCT and better power to ground ability, I think 3.2-3.3 0-60 is about right . The C7 Z51 does it in 3.8

I bet it lands around 500 hp. If it comes in at that power level, with the traction advantage of a ME over the C7, and the benefit of a DCT, if it comes in around 3,300 lbs - it'll match the C7 Z06 M7 on 0-60.

C7pimp

Remember that ME's do not have a long drive shaft and will put more power down to the wheels per engine HP than a front engine car. So, if a C7 puts down 410whp with 460 crank, a 500 hp C8 would put down about 455whp. With traction and that weight, DCT, a C8 could possibly pull a 3.3 second 0-60. That is damn quick.

If the base model is really the ~70k price point rumored, asking for more than ~475hp seems like a bit of a stretch, as does expecting 3200lb weight. Like stated, they need to leave room for the higher performance versions and going from FE to ME, from 460 to 525, losing weight, and keeping price at 70k seems like wishful thinking for one model year change.

My cautious guess would be 3400lbs, 475hp, 11.6 1/4 mile, and a $75k sticker to start. Acceleration will be insane for "only" 475hp with the extra weight over the rear wheels, since Vettes have been traction limited for decades. That would keep most people happy and still leave plenty of room for improvements on the big boy versions. It's not a pure race car and will obviously need things like leather, nav, intelligent cruise control, etc to be considered modern and keep many people happy, and along with all the govt mandated safety requirements on top of that there is no way it will be 3200lbs(hope I'm wrong!). A GS C7 is ~3450 and the ME supposed to have extra radiators, increased cooling, bigger and heavier DCT, etc. FWIW a 488 is 3250, and IMO there is no way a well loaded Vette will be lighter than that thing at a fraction of the price...losing weight is expensive.

Driveshaft length effect on drivetrain loss is negligible compared to the transmission used. A DCT has more loss than a manual, and will likely put less to the ground than a similar flywheel hp manual car. Note that we're only talking about 10hp on a 500hp car, but it is still less HP, not more.

WaxWeekly

my random number guesses...
500hp/tq
3500lbs
11.4 @ 126 (unless AWD)
1.15g skid pad

Honestly I'm more concerned about weight. Will this thing be nimble? Straight line speed is good but the real fun is how it handles. The lighter the better.

No different than the base C7 Stingray with 460 HP and an A8..

ColoradoGS

I think you are right about the weight. There's a crazy power race going on with performance cars now though. In the Best Driver's Car comparison the Motor Trend did that included the C7 Grand Sport, it came in 8th despite being one of the best handling cars tested. The quick summary review was "fantastic car, needs 100 more horsepower". There are a lot of performance sedans with 500+ hp nowadays.

I would hope that they get all they can out of the LT2. 500hp+ would be ideal. And then the DOHC and DOHC with TT versions can reach the expected Z06 and ZR1 numbers.

Z0Sick6

I think 500-505 for the base, 730 to 750 for the Z06, and I think the E-Ray ZR1 hybrid is something like 900-950 with electric and gas engine

This has been said by some people that do know some things and also many mags.
