    I'm confused though, you said Tesla's Ludicrous battery is 6.375 kWh, do you mean the individual modules that make up the 100 KWh battery?

    Four 1.94 KWh modules surely would indicate a PHEV. Do you think they would fit into the C8's center tunnel? Based on some measurements I found the internal volume is only about 2 cubic feet once routing for the coolant hoses is considered. I tried finding dimensions for the Bolt's battery modules but didn't get very far.
    Thanks for the kind words on the C2.

    Yes. Models S and X all have 16 modules inside the battery pack. So there are 16 of the 6.375 kWh modules in the C2 for a total of 102 kWh. I originally had Chevy Volt Gen 2 batteries installed, but at 37 kWh total for TWO complete sets, I figured it would be a real expensive golf cart. And the Volt batteries were a real nightmare to package in a little C2. I was able to package the 102 kWh of Tesla batteries much easier than the 37 kWh of Volt modules, believe it or not. With the 102 kWh Tesla bank, one could possibly get 300 miles of range. If one could keep their foot out of it. I'm sure I won't be able to keep my foot out of it on a regular basis, but I will try to hypermile it to see if I can get over 300 miles of range.

    All of the Tesla Model S/X batteries are approximately 27" long, by 13" wide, by 3" high. So Tesla can get that 6.375 kWh in a relatively small package of 1053 cubic inches. Two cubic feet that you have calculated is 3456 cubic inches. So one of the Tesla ludicrous batteries at 6.375 kWh would fit in less than a third of your calculated two cubic feet. So yes, I absolutely think Chevy could package 7.75 kWh in the C8 center tunnel.

    I have two of the ludicrous batteries in the forward half of my center, former transmission, tunnel. Only one module is installed in the center box in the image below. The device between the electric rack & pinon and the center box is a DC>DC converter and battery charger. It charges the high-voltage bank and reduces it to 12 volts for legacy electrics and electronics. The front battery box, which lies on top of those transverse crossmembers and two frame mounts by the firewall, holds 10 more modules and the rear box that is near the OEM gas tank holds 4 modules for that magic 16 module total. So from this image, one could imaging that C8 engineers could package 8 kWh in our center tunnel. Of course getting the proper 400 volts for the Ultium front-assist motor may be trickier, but that's a different discussion.

    I have also seen reports of the 1.94 kWh Ultium battery modules. Other reports say there will be four 1.94 kWh of those modules in the E-Ray. That is how I got the 7.75 kWh capacity referenced above.

    I agree that if there is only one 1.94 kWH module in the E-Ray, it will not be a PHEV. If there are four, it will be a PHEV. The jury is still out, obviously, if there will be one or four modules in the E-Ray. So what you are saying makes sense if there is only one 2 kWh module.

    With GMs push for all things electric being more of a philosophical thing, than a CAFE thing, I'm just thinking that the reports of the 7.75 kWh capacity may be correct. I guess we'll all see next year.

    No, but I do take a ship-load of pics every week.

    I'll create a build thread here on MECF when it's done, sometime in 2022. I'm doing the build myself, and I'm kinda slow in my old age.

    Tesla’s “Ludicrous” is a driving mode, not a battery. It's available on cars with 100 KWh batteries (battery weighs 1378 lbs). That’s without the coolant and associated heat exchangers, pumps, control electronics, etc.

    The NSX has a 1.3 KWh battery and the one report I’ve seen on the E-Ray’s battery capacity puts it at 1.94 KWh.

    Since they’re benchmarking the NSX a 2 KWh battery does make sense. It’s large enough to boost fuel efficiency and enable front wheel torque vectoring, but small enough to keep costs and weight low.

    The Stradale has both front and rear motors so its EV driving character is more sporting than a FWD mode, and I suspect the extra electric range is really about accessing markets that strictly regulate gassers. In many European cities gassers will be banned so the Ferrari needs enough EV range to roll on through.

    In contrast GM wants to maximize the fuel economy of the E-Ray with hybrid tech, explore the performance benefits of front electric motor(s), and demonstrate to Corvette enthusiasts that electric propulsion isn’t only about boring efficiency. 2 KWh is plenty and gives more of a buffer than the NSX does for capacity degradation so after 100k miles performance will be the same.

    I don't really see the point of a PHEV Corvette. Why lug around the extra batteries in order to have a FWD EV mode with 100 - 200hp? In city driving a hybrid E-Ray will still run mostly in electric mode anyways because of the regen. So a PHEV would require a lot of extra weight with very little payoff (and negative payoff with respect to performance).
    The Ferrari Stradale SF90 which I often refer to, has a 6.5 kWh battery module. The SF90 is a PHEV. I don't know what that Ferrari battery module weighs.

    The Ferrari costs between $500,000-$700,000. So the Zora would be a direct competitor, not the E-Ray. But the Zora would be at least 1/2 million bucks less. Go USA.

    The Tesla Ludicrous battery, at 6.375 kWh, is almost exactly the same capacity as the Ferrari 6.5 kWh module. It weighs only 55 lbs.

    The GM Ultium modules in the E-Ray have been estimated to have a capacity of 7.75 kWh. So with the newer battery chemistry and a confirmed wireless BMS, will the battery bank in the E-Ray weigh less than 50 pounds? I bet a dollar it may.

    If the Ferrari is a PHEV, why not would an E-Ray with a speculated larger battery bank be a PHEV, for electric-only operation?

I wonder however about the long-term popularity of this hybrid design, with many people being fans of the 100% naturally aspirated "tried and true" engines...and with the upcoming C9's being all-electric. Will the E-Ray be stuck in the middle and glossed over, in years to come? Or will it be seen as a popular bridge between the C8 and C9 generations and possibly "the best of both worlds" with its 6.2L engine and electric motor combo? Perhaps (?) a good topic for a member's poll John?
    I've just found this etags.com article which points to hybrid vehicles being more popular than fully electric vehicles, assuming their stats are properly quoted. Perhaps due to consumer fears about putting all their eggs in one basket and relying solely on electric? Regardless, I suspect this may change as more charge stations come on stream and manufacturers transition to electric only (assuming we first figure out a way to boost the grid's capacity). Food for thought.

    Man, I so agree. It would be a supreme waste if it were not a PHEV so we can get some local EV-only miles running it.

    Good question. I know my thought was that four months for its reveal after the Z06 would be its earliest time. But there are no set timetables nor other practices any more.

    It's starting to get exciting to see more of the E-Ray being captured in action. I wonder of the rumor of GM debuting the car 4 months after the Z06 is accurate. I'm hoping it'll be sooner as that will get the E-Ray list at MM going. Once you put the deposit down, the clock starts ticking all over again and the excitement starts to really ramp up.

    Thanks for the video of the E-Ray. I'm looking forward to getting one.
