whats the 0-60 in the 6 speed 2017 zl1 cant find anything? i know the auto is 3.5..and whats the weight differnce in the 6th gen SS to the new ZL1? the 6th gen ss lighter?

[HumanWiki]

It's not published. People are guessing and since we don't know 100% of the gearing ratios, they're wild shots. But probably close guesses with 3.7-3.8

All times for ZL1 are auto times.

[SDG23]

Not sure the exact weight difference but a 6th gen SS will weigh less than the 6th gen ZL1, I'm thinking a few hundred pounds? As for 0-60 I'm not sure but Al O said the 6spd ZL1 will do 0-60 in 1st gear. It might be a little slower perhaps than the auto but if it can be done in first gear, probably not much slower.

No specs yet on the ZL1 manual. Its probably a little slower to 60 than the 10 speed. Like HumanWiki, I expect it to be 3.7 or 3.8 seconds. That would be a similar drop-off to what the Z06 has auto vs manual, and a similar improvement to what the automatic ZL1 has over the SS auto.

It should be roughly 200 lbs heavier than the 6th gen SS, based on the fact that they've said the ZL1 will be 220 or so pounds lighter than the 5th gen ZL1. That puts it right around 3900 lbs, which is 200 more than the SS.

We know that the 6th gen ZL1 weights 230 pounds LIGHTER than the 5th Gen ZL1.

5th gen ZL1 weight = 4,120 to 4,374 lbs
So... 6th gen ZL1 weight = 3,890 to 4,144 lbs.

As for the 0-62, i bet it's 3.7-3.8.

Keep the custom launch control in mind as well also that how the SS manual says 4.x and I keep getting 3.8-3.9 with it according to GPS and car. So who knows.

Not published but I'm betting 3.6 easily.

[SS 1LE]

Well let us remember these are GM quoted times (the 3.5), which as of late for the Camaro have been pretty conservative.

They quote the manual SS as 4.3. Yet it has hit 4.0 in multiple tests. They are quoting a tenth quicker for the SS 1LE, and there are rumors that with its ELSD and stickier, wider, non run flats, it will hit 3.9 when tested under the right conditions.

So, with that being said..for the ZL1, I will say 3.4 for the auto, and 3.6 for the manual.

if you don't have to shift....why would it not be faster? Yes, I know is must have a very tall gear but if I don't have to shift from dumping the clutch to 60 and I have variable launch control...well....

Because, more times than not, the way an auto launches and the way a stick launches, the auto is going to win on a dig launch like this.

Its drive line is pre-loaded.

You only have to let off the brake and go. No slipping the cluth / throttle feathering. (even computer controlled launches in a single clutch don't really keep up with the TC in the Autos for this -- yet. They're much better, but you're still dealing with the clutch/throttle ratio and that's still quite manual on the human and prone to judgement and application error)

The effective gearing on 1-2 in the A10 may still be better than 1 in M6 and the auto trans will shift quickly enough to keep up over a tall gear. (if you've not listened to the A10 upshift, you should. it's super snappy). While the 1st gear on a ZL1 M6 may allow it to get to 60MPH in first, it will need a higher RPM redline to do so or a taller gear. If the redline/cutoff RPM is higher, then fine, it can pull easier from a dig and just rev higher. If you've got a taller 1st gear, then it will take more applied TQ from the motor per unit time to get to 60MPH faster. This is where your problem will come up, as it will be a skill requiring feat to get the 100% right amount of progressive TQ from the LT4, through the RPM range on that surface, on that day, in those temps with this tire to make sure you're getting to 60MPH as quickly as possible. The A10, with its insane 4.70:1 1st gear doesn't have to apply as much TQ, but will have to spin faster quicker (think the difference to your legs on a bike in 1st gear or 3rd gear and how it feels. 1st gear takes less effort (TQ) but doesn't move you far per pedal turn. 3rd gear takes more effort (TQ) but will move your farther per rotation) -- your engine experiences this effect as well. All of of this has to be factored in, with many other things, than just how many times you shift.

All things being equal. It's tough to beat the auto these days in a dig launch when both cars are pretty much the same otherwise.


**also, be careful when comparing some 0-60 if you see the "with XX rollout" as that's not technically a 0 movement dig and is not unlike shallow staging on a 1/4 to give you some roll time to not red light on the second beam and it can affect times, esp on the shorter things like 0-60

All good points. It should be interesting to see how this A10 handles the beating it is sure to receive, especially when people put drag radials on these things and line lock. I have vacillated back and forth but I know I have beat the hell out of the M6 in my current Z and it is as consistent at launch 10 as it was on launch 1. If there is a variance, it is driver, not car. I hope that is the same with the A10 and all the preload that driveline is going to have to deal with, especially the torque converter.

I had a three speed powerglide in my 69 for years and it was bullet proof at the track and a wonderful track transmission but it also had a 4K stall converter and was purpose built for 1000hp so I never thought twice about it.

Yes, it's usually down to driver skill at that point.. Some can launch well, some can't..... I still, to this day, will read Ranger's stuff... He's a stick master.

[iPODFAN11]

Al O. is quoted in the videos in another thread saying it will do 0-60 in 1st gear. Can't be too much slower than the A10 if that's the case. 3.7 is my guess.

[BAAD LS2]

Can't believe nobody asked him what clutch was going to be in the car...
