    Some are not happy with the origin of the V8 in the Corvette. It's okay and I respect their right to want to respect tradition.

    I can imagine, however, their reaction when Chevrolet offers a Corvette equipped with a 100 kWh battery, electric all-wheel drive and a 4-speed manual transmission on the rear axle.

    Well I'm confused, why would an AWD BEV Corvette have a four speed manual transmission?

    While I find the Corvette to be amazing. It is starting to get to the point that if I wanted one of the zoomier levels of performance I can't afford it and if that's the case then I don't want it and then I loose interest.....I never thought I'd loose interest in new Corvettes,but it seem to be happening ever so slowly.

    This is going to go the same way as the Camaro, the base level performance is going to be more than enough for most buyers, the really hardcore buyers will get their models but really not necessary for most buyers.

    And then you gotta explain that the FPC makes firing order and sound like two four cylinders.
    GT350 didn't sound like 2 4cyl engines... especially the GT350R in "piss off your neighbors mode" sounded absolutely viscous. I have zero doubt that a FPC Z will sound just as good, if not better

    I like the sound and to me, it does sound more like two angry four cylinders together than a cross plane V8
    the reason I pointed the sound out is because but I know that others who don't understand why it's different
    will bitch and moan.

    I remember watching an old IROC-Z with a flat plane Chevy strut it stuff and thinking
    what a high pitch snarl had, just like the GT350.

    IIRC there were also rumors of no GS for C7 generation. GS traditionally (C6 & C7 models, so back ~15 years) comes after Z06 to keep the lineup fresh, using a Z06 derived wide-body with some small/cheap changes. It has suspension/brakes/aero improvements from the Z-cars with some tweaks to integrate the overall package, using the base engine. I wouldn't expect to hear about a GS until a few years after the Z06 hype has died down. I also wouldn't expect the C6 and C7 GS equation to change much for C8, but it would be awesome if it got its own higher output N/A engine vs. the base cars.

Technology changes therefore the mechanicals need to change, as long as they deliver that promise of good looks and fun to drive. A Corvette (Camaro too) doesn't have to have a V8, it has to have a lot of power.
    I agree for the most part, however power characteristics/delivery could also be argued to be part of the Corvette experience. Many Corvettes are used as DDs, and the low end torque is appreciated. A smaller displacement TT engine using modern turbos, controls, etc. can definitely deliver in the low end torque department, but some of those engines lack the higher RPM pull of a high performance N/A engine like the LT2 (let alone the real revver engines like a 5.2L Voodoo). The rumored 5.5L DOHC FPC engine would likely have a lot less low end grunt than the LT2 in the base C8, but have the performance revvy nature and high RPM power. So maybe that works in a Z06 track special, and the base LT2 still appeals to those used to the OHV power delivery. At the end of the day, if GM chooses to call it a Corvette, it's a Corvette. GM never seems to have issues selling the models that have departures from heritage like losing pop up head lights and round tail lights, so it's likely they'll be okay here too, as long as they keep the performance, overall experience, and looks, as you said.

    Happy to be proven wrong but,
    GM did spend money on exclusive engines for Cadillac that you just couldn't get in a Buick or Chevy or a GMC...
    And while you're right that all come from GM powertrain, GM loves to cloister its most interesting engines
    away behind walls of high priced exclusivity. No such pretentious behavior from Ford with its EB V6s.
    Agreed.

    Also it doesn't seem likely that the Corvette DOHC engine will share much with the Blackwing aside from being DOHC and V8. The leaked CAD shows that the Corvette engine will not be "hot-V", so turbos outside the V will drive heads to be different. Sounds like the rumored displacements will probably need a different bore and bore spacing (Blackwing bore spacing can't support much more, and it already is a long stroke engine), so now you have a different block and pistons. If some or all the versions in Corvette have FPC, now you've got a different crank. Different power and RPM targets probably mean different valve sizes are required, so the valvetrain is now different too. So anyway I think a lot of people jump to assume a Blackwing relationship with any GM DOHC V8, and there may be some knowledge sharing and certain parts that can be shared, but I think it would be a stretch to assume they are the same architecture at this point until we know more. Can't wait!

    About a year ago, I read something about the C8 R race version for Le Mans requirements
    were something like 300 road versions to homologated the engine, maybe limited number
    and exclusivity....the irony is that just like the Ford GT, the road engine will have more power.
    Last year, the racing 5.5 Corvette engine was limited to ~500 HP and 480 lb ft..

    Interesting analysis on bore and stroke of blackwing and while I agree the hit vee twin tirbo set up will be replaced with a more traditional twin turbo layout in the c8 z06...

    Im not quite sure a 3.9 liter version of the blackwing wouldnt easily match ferraris 3.9 bore and stroke

    86 x 88 for the ferrari 3.9 versus cadillacs 86 x 90 mm bore and stroke on the 4.2 twin turbo blackwing.

    https://en.m.wikipedia.org/wiki/Ferrari_F154_engine

    Seems adjusting stroke for the reasons you mentioned would be quite simple for the corvette team.

    I dont know the answer to the question being raised.

    I just feel meeting performance, emissions and fuel effociency tests the twin turbo layout is better suited for performance vehicles these days.

    Its really the emissions and fuel efficiency of forced induction that leads the charge even for extremely high performance vehicles.

    Naturally asporated motors could easily meet the performance critera requirements..lits the fuel efficiency and emissions that puts a strain on using naturally aspirated even for GM. The masters of naturally aspirated designed powerplants.

    Id be surprised to see the z06 with a naturally aspirated powerplant in this day and age reaching power levels required for supercar killer status. JMO

    Very good insights, for me without an engineering background, I have always wondered why they didn’t build upon the LS motor in the C6, perhaps increase compression ratios and wring out more power, up to 550, perhaps, and keep the same architecture as well as Tradition of OHV character.

    The 2012, 2013 Z06 Centennial edition still remains for me the quintessential, Z06, Manual, Naturally aspirated, less weight than its Ferrari contemporary, and an absolute beast at the track. Even today, that thing will take down a lot of unsuspecting super cars.

    Perhaps update it with a DCT.. but keep the Lotus Formula.. lesscweight, track focus..

    Yup, and I would throw in a/28 spool valves from multi matic..for the ultimate track weapon...

    I think the GS could have accomplished the sales targets of Corvette without diluting the Z06 brand.

    Once there was an automatic.. and more weight.. throw in the unfinished track readiness of the C7 Z06, the brand is somewhat tarnished...

    other places are refuting that it will use twin turbos.
