Default C8 platforms for the next 5 years !!

Here are my thoughts on what GM will do with the C8 and its trim levels
Base stingray - LT2
C8 Z06 LT6 Widebody as show already ( Due out late 2022 as a 2023 model )
Eray EV AWD w LT2 power in rear ( fastest Corvette 0-60 ever built until ZORA ) widebody ( 2024 model but debut late 2023 )
Grandsport LT2 but with Widebody
ZR1 Twin Turbo LT6 New Designation Will be LT7 ( around 800 hp ) RWD & debut late 2025 or later .
ZORA !! Ultimate LT7 Twin turbo aforementioned powerplant but with AWD from ERay ( 1000 HP AND AWD ) my guess this car will appear in the last year of C8 production .


I wouldn’t be surprised if the ZR1 and ZORA have a super wide body configuration .

All electric Corvette ( SUV with all electric ultium propulsion system ) to compete head to head with tesla !
This suv will come out very very soon possibly late 2023 , this is the car GM refers to as an all electric vehicle .

Before covid Corvette was set to be its own brand ( and depart from Chevy ) but will remain a Chevy brand for the immediate future .

The C8Z06 will be out late this year; '22.

My interpretation has always been:

Stingray - LT2
Z06 - LT6 NA
ERay - LT2 eAWD
ZR1 - LT7 TT
Zora - LT7 TT eAWD

However the GrandSport name trademark was retained, and we know there are more electrified goals and a Corvette-branded SUV just makes good business sense. Also, there are rumors of Camaro going away and coming back as a BEV SUV.

Who knows... I love the speculation and fun around a new generation (C9) but the C8 gen will probably be a long run if they want to have all these variations. I'll be getting a Z06 later this year and will keep that car forever. Don't much care for an electric Corvette, but a SUV to add to the garage I'd be interested in.

I think once people get a taste of the power of an AWD ERay , in two years and its faster 0-60 ( I speculate ) than the Z06 , many will switch over ( some wont ) .

Well if I was GM, I would take the Z06 and ADD the electric motor(s) of the ERay and make the ZR1. I would then take the ZR1 add twin turbos and maybe more powerful electric motors and make the ZORA.

Although that would be a great idea . Some corvette old timers can’t fathom owning a vette with electric AWD . So I think if people had a choice between the twin turbo ZR1 RWD OR the AWD platform with the 5.5 floatplane crank . They wouldn’t choose the latter . For me I agree with you . I think it would be awesome . But GM has to decide where its buyers lay , there demographics and habits . But who knows but Itll for sure it’ll be one or the other . Either way its gonna be cool car .

Thank God you're not GM.
The next Z model with have the twin turbo engine form the leaked CAD drawing GM Legal had removed from the internet 4 years ago.

Perhaps. But my version of the ZR1 would be quicker 0-60, probably quicker 1/4 mile, and handling course would be very interesting because of the advantages of AWD and torque vectoring. And I am not sure if I would be quoting a CAD drawing from 4 years ago on a car not coming out for another @ 2years from now. 6 years is a very very long time in auto planning. And as for streetable, my version would be far superior in almost every relevant way.

Sorry guys, I think Z06 is the last of the ICE cars. Maybe they add electric to it, but that is all. Of course Grand Sport could be just like the C7 but that is really just a Z06 with less HP. The E-ray is going to be fast and frugal -- the fastest 0-60 ever and the best fuel economy ever. With AWD, it will dominate the streets.

Wrong.
GM didn't spend all the time and money on the twin turbo engine in the verified official CAD documents to not offer a C8 with it.
Thank God neither of you are in charge of anything at GM.

Twin turbo would generate too much heat like the C7 Z06. GM is not going down that road again.

Dumbest post from you in a while, and that's saying a lot.
All the top sports car manufactures are running twin turbos without heating issues.

The C7Z was SUPERCHARGED, it did not have twin turbos, and even GM solved the heating issues with their SUPERCHARGED engines in the ZL1, ZR1, CT5 and Escalade Blackwings.
And yes, even the C7Z had it's cooling resolved. Not to mention, the potential cooling issues never presented themselves on the street, and only on a track when pushed.

The next Z model will have the twin turbo engine from the leaked CAD.

So out of mild curiosity if GM could add the electric motor(s) of the ERay to the Z06 and call it the Grand Sport and then add twin turbos to the Z06 and call it the ZR1
Which one would you buy?

AND would it matter if the Grand Sport was quicker 0-60 AND quicker 1/4 mile AND better handling on some road courses AND less expensive AND got 50% better MPG in the real world. Just wondering if ALL that would make any difference in your choice? Assuming/guessing your first choice would be to buy the ZR1. And for the record in my proposed configurations, I did give the Zora the twin turbo motor.

my prediction would be Z06 and Eray will be your last ICE models... Id imagine if they do a ZR1 or "Zora" that theyll be full electric awd. I have to imagine with recent developments and the industry push towards full EV that GM's initial plan for the sub models of the c8 has changed drastically. As much as I'd like to see an awd twin turbo hybrid I dont see it being in the cards... It would be such a low volume car anyway I dont see GM putting the money there in development. Most people thought we'd never go Mid Engine yet here we are... I hate to say it but ICE Corvettes are living on borrowed time. Full EV is coming and much sooner than any of us hoped. I hope I'm wrong but the world is changing like it or not.

May have been the plan BEFORE Mary Barra (and top execs) decided to go all out for EVs. In fact to meet the 2012 outlined and the press release that said starting in 2017 and by 2025 the whole Corvette family (Porsche, Ferrari etc) were REQUIRED TO ACHIVE ~40 MPG. All, even the base C8 Vettes would have to be all out hybrids where the LS2 only started AFTER the ~100 hp electric motors brought it to 30 to 40 mph. Would have a large battery that filled the center tunnel. No doubt also a plug in recharge option.

There could have controlled the Zora with price so it could get lower mpg as the REQUIRMENT was the average of all. I'll include the press release that doesn't mention the lower numbers BUT STATES the average of all cars sold in 2025 would achieve 54.5 mpg!

That was when reasonable logic prevailed as a way to cut CO2 emissions. It was stopped with Pen in January 2017. A new Pen April 2022 quietly announced a 49 mpg requirement in 2026 with few details.

But Mary joined the current administration goal, took half the Corvette engineers over a year ago and stated, "They will work on EV's (and not Vette EV, EV's in general.) They are putting billions in battery production and EVs and have said all cars and light trucks will be EV's in 2035. I'm afraid performance oriented ICE car folks are in for disappointment. The zealots will not allow folks to pollute the would with CO2 using a gas guzzler tax!

That said, the GM President announced a few weeks ago the hybrid will be released in 2023 (assume it's the "Performance Hybrid" already reported in a leak December 2019.) He then said followed by an EV Vette. That prompted the Name Change from E Ray for the performance hybrid to GS (funny speculated that have when the hybrid details were leaked December 2019 and posted on the Forum) so E Ray could be used for the EV Vette being announced much earlier than initially planned.

IMO that was a change NOT for the Vette BUT to get folks who buy Grocery Getters excited by an EV Vette! Right now a small percentage of folks want an EV! It's going to take Marketing and continued high gas prices to get that done.

Support for the above:
FIRST: EPA Press Release, Cars will achieve 54.5 mpg in 2025:
https://obamawhitehouse.archives.gov...iency-standard

This is a page showing key items in the1174 page Report the Press Release was based on. I read the report. It had an interesting comment. It said a way to push out ICE's was to raise the Federal Gas Tax! Bet the zealot EPA folks are with the current gas price!

This is the beginning of the end for the Corvette. Add to this that five auto companies this week announced their support for California's C02 emission standards: Ford, Volkswagen, Honda, BMW, and Volvo Good luck with that. They foolishly just walked into a trap. Next come the MPGe standards from California. If California isn't already working on it, they will be soon. Count on it. It would all be within the "climate change" realm. Maybe I'll call CARB and ask them.

Here are some examples of EVs at the bottom of the MPGe list.

Porsche Taycan
Audi e-Tron
Ford Mustang Mach-e
Tesla Plaid
Polestar 2
BMW i4

Buh-bye performance cars.

Yep, I believe it was those 5 who had supported California's attempt to implement the EPA requirement that included the Corvette Family (Ferrari, Porsche) achieving ~40 mpg in 2025 after the planned Federal Law was stopped by a Pen in January 2017! That agreement was very similar, delayed until 2026. It was stopped in Court! The April 2022 49 mpg requirement that was announced by the "current Pen" details have not yet been defined.

This is what the Washington Post said., re allowing CA to set their own standards:
"The next step for the EPA is to craft a new climate rule for cars built after 2026. With the waiver, California is now in a position to prod automakers to make deeper emissions cuts — even without the federal government’s help. That influence will be especially important if Biden isn’t elected to a second term in 2024 and a president with different views on climate change takes office."

Don't think many understand (or want to) the implications!
