Hell who thought a 5th gen could go 11.5 Dave lol.

The only way to know for sure which one is quicker is to mount a set of drag tires on them, and run them side by side.

From one on my CTS-V buddys that was there for the ZL1 runs at MIR

from EVIL_V


after having 40 plus passes on my stock 2016 CTS-V which has the same intrusive tq management/traction control, I don't think a 60 foot better than 1.68-1.70 is possible. on street tires it pulls 1.80 60 foots and according to the PDR its 3.7 seconds 0-60 (just like they advertise). I honestly think it would do the same thing in the rain.

the ZL1 seems to have the exact same issue in talking with the guy that had the 2017 at the track Saturday that went 11.3. he put on my drag radials and didn't go any quicker. the car doesn't spin hardly at all with the tq limiting in the tune.

I logged mine, and it does not go to 100 percent throttle till 25 mph. you can hear it from videos of my launches. the ZL1 did the exact same thing.

I made the comment that there will be lots of disappointed ZL1 owners/buyers with the 1/4 mile performance of the car. but the reality is that it will do exactly what its advertised to do and probably not much faster unless it is tuned or there is some pat you head, turn around 3 times trick to turn it off.

That's interesting and disappointing at the same time. Why would GM limit throttle response in 1st? I would think this could be turned off in a setting somewhere...

Does this mean the M6 (given it allows you to go 100% throttle in 1st) has potential to go faster in the 1/4 than in auto with both having DRs and equal driver? Let me know if my logic is flawed...very interesting topic!

its not really to do with traction control, but more commanded tq delivery being limited. probably to keep from breaking stuff

I think you guys need to give it more time! It does have some traction management issues, and it is worse on the manual transmission cars, everyone says it is to protect the clutch. The Z06 has ran mid-high tens a bunch on MPSS tires and guys are cutting some pretty good 60 foot times. Also PDR does not include roll out like on standardized testing. So if PDR says you ran a 3.7 it's most likely actually a 3.5 or 3.6.

When I was listening to the in-car video of the white ZL1, it sure sounded to me like it short shifted from 1st to 2nd vs the rest of the shifts.

If it does, is that part of the torque management?

Give it more time? This is a function of the tune; unless your willing to void your warranty the best 60ft your gonna cut is a 1.7x. The ZO6 does not come with the same tune as a ZL1 or CTS-V

HPT just released a beta to address this. I'll be able to update tomorrow night if it worked. But the car (M6 SS, not ZL1) feels day and night different.

Just curious to your comment "best 60ft your gonna cut is a 1.7x" where did you get this data from?

the ZL1 appears to have the same TQ Management issue as the 2016 and up CTS-V's just from the several passes I watched on Saturday with the new ZL1.

I have tried every possible way to launch my V3 and the best 60 foot I cut was 1.70. my previous 2 V's cut 1.4's all day with no issues. A stock V2 will pull high 1.5's on drag radials, so to me there is no reason why a V3 (or ZL1) with more power, lighter weight, and steeper gearing shouldn't be able to pull at least a 1.60 on drag radials. But no matter how I tried to launch the car, it was 1.7-1.80 60 foots, drag radials or pilot super sports.

the pcm still limits the throttle in 1st gear even with traction control off.

so if someone is going to leave the car stock and not mess with the PCM/TCM, then im pretty sure that 1.7's or some high 1.6's are the best these cars are going to do. I hope im wrong, and someone figures a way out to turn that off, but in speaking with the Cadillac chief engineer, that's the way the car is set up and cant turn it off...at least for the V3.

Big Dave can vouch for my experience with these cars, both LSA and LT4 platforms....

I can most definitely vouch for Brian's knowledge when it comes to most things ls, lsa, or lt related. Unfortunately, his findings are very discouraging. I was hoping that because those passes were made in not so good conditions, there was much room for improvement. Any hope of challenging the Hellcat is pretty much squashed if this car isn't going to launch any better than a 1.7 60'

nope, not weather related. I experienced the same thing in the fall when I went to the track after I first got the V3.

Thanks for popping in here. I thought holding the PTM button down for 10 sec would turn it all off but after trying that I did get a little wheel spin but could definitely feel torque management holding things back. I had hoped to press the issue of a dig race against the Hellcat next month but not sure that's a good idea now.

Also, what ECM does the 17 ZL1 have (E78?) I hooked up HP Tuners last night but wasn't sure.
