Clearly the shifting sucked in the ZL1. The Hellcat would pull a half car on every ZL1 shift. I think an Auto ZL1 will beat the Hellcat, but not by much.

Honestly, I kind of thought the ZL1 would have beat the Hellcat even with the bad shifting. I mean a Hellcat is usually a 125 mph trap car....surely a stick ZL1 will trap that..?


This is a repeat of Hennessy's Z06 vs ZL1 test a few weeks ago, the Z06 driver was straight up TERRIBLE.

Hennessy probably has both of these cars parted out by now anyway and their parts for sale on eBay.....and the cars were probably loaners...lol

As expected. Auto to auto should be close.

Umm, the auto ZL1 is faster around a track then the manual ZL1. Though I am going to pre-agree with you that a stick is a whole lot funner and more involved then a auto on a track.

In a auto ZL1:
10 turns of perfect shifting/downshifting/holding gears followed by 1 time it doesn't do what you want and there is nothing you can do about it. NOTHING.

M6 ZL1:
10 turns and there is probably 2 times you made a error that could have improved your track times. And you know exactly what to do about it. And that perfect lap or two that you absolutely nail? Pure bliss that erases the 8 other laps where you made slight errors.

It's not like 90% of regular road course drivers are actually out there trying to earn a living off of it. Those that are, will undoubtedly drive the auto's for the consistency.

I don't care about all that. I like driving myself.

ajrthom makes a good point about Hennessey when it comes to the last test they did and the whole shady business.

It's always been stick for rolls and auto for digs.

Then the Sis Gen ZL1 M6 gets gapped on a roll, all of a sudden it's automagic for everything. lol

I just came back from a little cruise with a buddy in his GTR. Ran into a guy with a new black ZL1, open road, lined up and the guy rolls his window down amd says "only has 100 miles" and didnt want to race. Bummer.


That is, IF Zyborg learns how to handle all his new found powa and can shift decent.....I know that was a few "IFs".
Had a chance to test the shelby vs my buddies GTR with only a mid pipe. I expected to get him, but race was dead nuts even. Very dissapointed in the shelby. Ran him in Comp mode. Not sure if that is affecting how the car runs in order to keep traction. Need to learn this car better.

No Idea, I just turn all nannies off and rip gears.

Adjustable upper and non adjustable lower control arms, then roll on 305mm MT DRs at 20psi.

I think times have changed to where the autos are better on rolls. It only makes sense to. The only real advantage the stick cars had on rolls was better gearing/more gear choices and a little better efficiency. Now the autos have gained alot in efficiency and have more gearing ratios and shift quicker than the manuals.

It only makes sense.

Regardless they admitted to not shifting hard. And it was obvious.

Guess we will see what happens when they test auto to auto. Although from a roll the weight isn't as much of a hindrance to the hellcat.

I've always been unsure if the zl1 would be faster but I'm guessing the a10 should do better. Especially compared to casual shifting

I'd be stunned if the auto ZL1 beat the auto hellcat. Wouldn't be surprised to see it a damn close race though. Like I thought when they announced the HP of the ZL1: "nice, but not enough to dethrone the hellcat".

A=F/M changes on a roll? Is there a fudge factor that I'm not aware of?

I agree with this, the math wasn't really in favor of the ZL1.

I do think the ZL1 is a better platform than the Fatcat and I was actually hoping the ZL1 would have took the title.

There are some here who can bang gears. Some will never.

I don't think there is much doubt the zl1 will beat the hellcat. Auto to auto or stick to stick.

As quick as the lt4 has gone in the vette stock and lbo it's a given.

An auto CAN better on rolls. There are big losses through the trans. The manual needs an extended power band. My power and peak at 6800 and holds flat to 7800. I have a 1500 rpm drop in shifts. Same result as an eight speed. Never dropping power on shift. Of course I can't shift there until a magnum trans but the point is, a manual has the power advantage.

This isn't the 8 speed...it's the 10 speed in the zl1. So there lots of improvements even vs the 8 speed with was pretty damn good.

It's probably a good thing GM is moving to a A10 that was co-developed with Ford.

Starting to hear of a few GM A8 failures as of late. I know of one C7Z that is on it's 3rd A8. They race it hard but the first trans failed bone stock and GM wouldn't warranty it....due to them racing, which I thought GM didn't have issues with.
