Once the flat-plane Bi-turbo Z06 comes out... it's game over for the other manufactures no matter who they are....

I got a $500 phone app that gets my BMW 335i into 11's.... I can only imagine the tuning potential for the C8 Z06...

 

The Porsche website lists the 911gts as 0to60 in 3.7s which makes more sense for the power and weight.

Now they are saying flat-plane 32v non-turbo Z06 in the 600hp range...

 

Disagree. As an old drag racer it’s all about gearing. The C8 Z51 has. 571 rear end ratio. It has to shift three times to get to 60. Has a diminished top end as a result and who knows about mileage. The nine speed DCT helps. The rear tires on the C8 are smaller than the C7 Z to be sure. Not traction but gearing.

 

It is a 5.17 rear not a 5.71, and all the gear in the world is no good with out traction . The mid engine set up allows 60% of the cars weight over the rear wheels making superb available traction , and that allows the use of aggressive differential gear ratios.

 

Porsche always is very conservative with their performance figures.

 

Question, at the reveal it was stated Z51 optioned car is under 3.0 seconds, now that we know MT tested the car and is embargoed, when the heck is Chevy going to release its actual numbers? Or will MT and other testers be the way we find out what under 3.0 secs means?

 

Motor Trends test results are usually easily beaten by end users shortly after deliveries begin.

 

I can easily testify the truth and reality to your statement that I easily exceed MT's published results with my C5, my C6 and my C7 all on street tires and without any mods or tunes. Later after a couple of years a few mods , like a cold air intake , bettered their times by .3 to .6 seconds. Add drag radials and you pick up another .1 sec. Just stating the real facts.

 

Exactly. 0-60 and 1/4 mile times are influenced by surface conditions, DA, driver ability, etc. to the point where splitting hairs about 0.1 or 0.2 seconds is utterly ridiculous as the #s will be all over the board. This Z51 debate regarding acceleration is the same stupidity that was seen when the C7 was introduced with identical power for both Z51 and non. The expert internet racing champions here who blindly fist pound about being able to "feel" a difference of one tenth of one second 0-60MPH make the foolish assumption that these metrics will be reproduced in identical fashion on any day, at any temperature, on any surface, and on. The variables here are nearly endless. Once again, nonsense, absolute nonsense.

 

I agree it is a head scratcher...as an example the new mid engine 2020 Ferrari F8 is 710 HP and 565 Ft lbs of torque and weighs less then the C8 and is DCT. Ferrari claims 0-60 in 2.9 secs....which seems to be the number people have latched on to with the "we are seeing sub 3 seconds" comment at the C8 reveal. Here is my take; 1.) I expect an objective test with Pro driver on a good surface with OEM tires that actually starts from a dead stop (Fyi, even MT allows a 1 mph roll in their "0-60" tests) to not be under 3 seconds 2.) Gearing, gearing, gearing. I think GM is placing heavy emphasis on the 0-6 and 1/4 times whereas, for example, the F8 is also a 211 MPH car. 3.) Finally, w/o AWD it is almost impossible to get a car under 2.9 seconds, whereas with AWD it can get way below that; the 2019 911 Turbo S is verified at repeatable 2.5 second 0-60 times and mid 10 sec. 1/4 times.

 

So from a dead stop you did better then 3.0 seconds (MT's C7 Z06 best time...and btw they use a 1 mph roll) with Cup 2's in a stock Z06 on a flat surface with no appreciable tail wind? I think I would need to see the data to buy that.

 

Really? I have never seen a Stock C7 Z06 on Cup 2's run a dead stop 0-60 on a flat surface with no tail wind in under 3.0 secs.

 

Lots of cars both front and rear engine have gotten to 60 in less than 2.9 seconds. You illustrate that with the Pooch example. The turbo Porsche, micky McLaren, and even a decently modded C5 will eclipse that 2.0 to 60 number

As an extreme example, a rear wheel drive top fueler hits zero to ONE HUNDRED in .8 seconds. As the power goes up, traction is at a premium but 4 wd is not necessarily the solution. Weight distribution, transfer, and the sheer grip of the rear tires can negate the need and the drivetrain loss and weight is less.

C8 Vette does 0-60 boogie with lots of gear, low end torq, and traction. No real magic here. It is however a huge testimate to the efficiency of the drivetrain and ability to put the power down.

Vette punches at a weight class above it's own competing with cars costing 3-4 times as much and can be fixed for 3-4 times less. Pretty good deal. Ferrari and others gears their cars also for more top end which can hurt the 0-60.

Put the same gearing into cars with more power as long as you maintain the grip and they will shade the vette. The old ZR-1 would do it if it could put that massive torq to the pavement. That's a big driver behind the c8, increasing efficiency and a much better platform for more power to do something besides produce smoking rubber. Spinning ain't winning.

From prior generation vettes, that 0-60 times didn't plummet as HP went up, spinning ain't winning and the new vette will get with the program much quicker. I think something that will be interesting is to see how much power the dct absorbs. This c8 drivetrain should reduce parasitic drag and allow more of the engine HP to make it to the tires by eliminating torq tube drive shaft and parts along the way to get the front engine power to the tranny. My bet is that the parasitic drag penalty is less than 15%. Interested to find out!

 

MT allows a roll out deduction of .1 or .2 to replicate your time at a drag strip. A drag strip timing system has the built in roll-out timing sequence. When you stage your vehicle on the starting line, you have a pre stage upper yellow light and a lower staged yellow light, when you edge up to the staged light (just about tickle it on) you are starting as far back as possible from the beam you need to break that says you have started to take off, the distance to that beam is called roll- out, they say that roll-out is worth .2 in your 1/4 mile et. Example, your ET is 11.8, but real world with no roll - out you actuallly ran a 11.9 or a 12.0. The Mid engine has a 5.17 or a 4.89 differential ratio, that with 60 % of the cars weight on the rear wheels and decent sticky tires a 2.9 or 3.0 to 60 mph is obtained. Its a dead hook with no tire spin and no nannies.

 

usrodeo4 , I guess you don't read very well. I never said I had a ZO6 with a ZO7 package but I had a C5 which MT said at best would turn 13.2 in the quarter with a M6 trans. I turned 12.6-12.8 all day long. My C6 with the LS2 and A6 GM said would turn 12.6 and MT said 12.8. I turned 12.3- 12.4's all day long on street tires. Then MT and GM said my C7, A6 would turn 12.2's but some how my 2014 Base Stingray turns 11.8-11.9's on street tires. My point is don't assume anything that MT or GM says. Okay?

 

Well then, if you haven't seen it or heard about it then it hasn't happened. Right?

 

The C8 has the weight on the rear. The C7 Z06 is 2.95 0-60. The big Torque from the V8 and the over 14 to 1 over all low is another key!
For the fast 0-60 from the C8

 

[QUOTE=BJ67;1600056752] Very true!
The 60 ft time (or 0-60 mph on the street) is the most important number for the 1/4 mile. The C8 has a much lower over all first gear along with the more weight on the rear axle and will make a quick 60ft.
The power to weight will show when the car is moving and no longer has the gearing advantage. The C8 will beat the M7 C7 Z06 on the 60ft times and may hang on though the 1/4 from the huge gearing advantage and physical advantage from the traction.
But rolling races between the 2 on the hiway would show the C7 Z06 easily puling away from the C8.

 

-[QUOTE=SpeedyVette;1600195233]Hmm, recall when I was 17 and foolish! Friend had a new 1960 Ford 2 door sedan, looked like a sleeper but he kept the 406 (cid) flags. Unlike the 4 speeds everyone "had to have" back-in-the day his had a 3 speed with overdrive. We'd park at the local hang-out and everyone wanted to race. As you say, it was a rolling start with "kick-down" selected by the person challenged. He's wait, agree on the amount and say "kick-down at 120!" Everyone had numerically high ratio gears and were lucky to hit 120! Never did race!

I grew out of that foolishness at 18! Crazy when there are lots of drag strips all over the country. On Wednesday nights folks do race for money at the strip around here!
