Hey all. Spent a little time up at Laguna Seca today watching the new ZR1 lapping and testing. Jim Mero and Alex McDonald were doing their testing and analysis of both tall wing and low wing ZR1's. I have a thread on the C8 forum that shows some video's and more info. Thanks to SBC And A Stick for putting these videos on his Youtube account. Thanks George.

Nice. Thanks for sharing

It's funny seeing everyone calling it a ZR1 when they don't know what it is.

Thanks for the vids OP.

What would you like it to be referred to as?

Garret

Indeed !

Thanks much for posting these. Much appreciated!

GM could easily follow the Camaro ZL1-1LE release and offer a revised Z06 Z07 track package option complete with optional rear wings to improve downforce.

I would hate to think with the admitted and non-admitted issues associated with heat soak and the need for additional cooling for the "most track capable Corvette ever" C7 Z06, that any such improvements such as a remodeled intercooler, hood vent and front fascia vents, would only be limited to a new, higher cost model "ZR1" effectively making the Z06 a non-contender, at least for the hard core autocross and racing crowd.

I am hoping this camo mule is simply the improved 2018 Z06 that will include a HP bump, improved cooling, and improved (and optional) track aero. The LT4 can produce more HP, it just needs to be cooled better with some re-engineering that will allow auxiliary radiators, fans, etc. Plus, any additional cosmetic improvements and model differentiators are welcome to further separate the Z06 from the Grand Sport.

C'mon GM, do us right!

Thanks! Very cool.

........been saying it's nothing more than a track package. The new car will be a 2020 model with a summer 2019 release.

There appeared to be two ZR1's with the low wing and two ZR1's with the high wing(one of which is not operable and is not available now for testing). There was also a ZO6 there that was testing. The ZR1's were much louder than the ZO6 and like SBC and a stick said yesterday, the new larger 2.6 liter supercharger from Eaton would pump substantially more air into the combustion chambers that would give it a deeper exhaust sound. I also noticed the two center exhaust outlets appeared to be larger than the outer two (though not absolutely positive of that) which could be larger diameter exhaust system from the exhaust manifolds back. I will get a better look this morning. There was also the narrow body Stingray with Grand Sport like Aero on it which was really hustling around the track. Made me wonder if it was a updated modified LT1 which could be a 4th year refresh of the LT1 for the Z51 and Grand Sport hierarchy. All of this makes sense from their historical management of their models that we've seen before in the C6 generation. And the speed of the gear shifts definitely had Auto or DCT like quickness. Listen to video #5 and you can hear the gear change just pop with it's quick change. On video #6 you can hear a very smooth gentle gear change when backing off of the throttle when going from turn 6 going up to the Corkscrew. That reminded me of the 8 speed Auto Trans ability to smoothen out the gear change. There was the Camaro ZL1-1LE there also with it's new 10 speed Auto Trans. Very quick but not Corvette quick. I was timing both but all cars were backing off at the sound booth. I'll report later

video 4 and 5 definitely sound supercharged.

Great vids and information---thanks! Makes me wonder about why a V6, twin cam, etc. with that kind of power, performance.

HPT

That is not a characteristic of a dual clutch trans. I'm almost certain the non-MT transmission will be a standard auto, most likely the 8-speed carried over from the current Z06.

Factory DCTs simply can't handle the output this car will generate. Case and point, the new M5 going back to a standard auto when the outgoing model has a DCT. Besides, I don't trust GM's engineers to design a DCT over and above anything currently on the market from Germany or Japan.

It is going to be a Fun summer!

skank

They are definitely supercharged.

I'm also thinking 8sp. auto as the power band must be massive. And now that there is sufficient cooling the auto could be a viable alternative to a DCT.

Hopefully the gas tank is a little bigger otherwise you would need to refuel every session at the track. I can't even get two full sessions at the track without refueling in my Z06.

like others said, this will be an A8. It's still a Z06 platform. GM already said no supplier have a DCT for this kind of torque that can fit in the Z06 platform.

(ZL1) Z06, and Z51, A10 transaxle/cooling - (small wing)

(1LE) Z07 - Grand Sport - (small wing), and Z06 - (larger wing)
