Agreed. Still way better than the SR but looks like not against the z06 which is understandable. Can't let the ERAY be faster than GM's current golden child lol.

The ZR1/ZORA should put everything to rest though. FI, and possibly AWD. It will be GM's version of the SF90.

Insane 0-60 and wicked top end. What a time to be alive!

The ZR1 would be the ultimate. 1/2 of an average mortgage? Use Bucket List as a reason to purchase such a vehicle for myself? I could try that on my Mrs.?

On the flip side the Mac blew by the E-Ray like it threw out an anchor, not saying the E-Ray is slow just physics that the Mac being lighter/2wd doesn’t put power down as well obviously from a dig.

I hate seeing people get all insecure about their cars, we buy them for a reason, to enjoy them.

Some guys, like me, love the sound and feel of the car more than anything, for us the C8 Z06 is the ultimate Corvette

Some want the quickest from light to light or 1/4 mile from a dig, for those the E-ray is the perfect choice.

Guys who track their cars on road courses will want the C8 Z06, however, the AWD provides security on those courses for non-professionals or occasional track guys.

Guys who want a daily driver for all 4 seasons will pick the E-ray.

Some guys want a comfortable daily cruiser and the regular C8 is perfect and plenty fast.

Top speed guys might actually pick an older ZR1 or the C8 Z06.

The point is, don't bash the other guys choice.
I chose a C8 Z06 HTC for the sound and the thrill of driving it provides.
I still wouldn't mind the E-ray in my stable if I did not have a Porsche 911 Turbo S.
I really liked my 2023 C8 Z51 HTC I owned before until it got lemon lawed, but either way I would have traded it for the C8 Z06.

Just remember, there is ALWAYS somebody faster, but it doesn't matter to everybody.

GT3 guys could care less about how fast a Turbo S is.

It's NOT the extra E-Ray weight that is the main cause as you say, "throughout the anchor!" It's the E-Ray electric motor reduces power output considerably after ~100 mph. Can watch the Cammica Video, no doubt with GM folks dictating what is shown, so up to~100 mph you can see the electric motor output power (look at my graph made from the E-Ray dash data.) HP output peaked at 43 mph and stayed pretty flat. Cammisa stated it dropped well below 100 hp near the traps BUT they did not show the dash display.

Look at the graphs I provided as it's typical for a high rpm multiphase EV motor as it gets into its very rpm, max ~18,000 rpm. Yep the 750S, 740 NA hp @ 7,500 rpm beats 495 LS2 hp with whatever extra the Electric motor provides. But as the poster said IF not Tracking, who cares!

Folks Tracking should buy a Z06 and best with Z07 option. NOT what the E-Ray is best at doing.

To be fair, the 765LT also blew by the z06 like it was standing still. But that's about hypercar status though.

Macs are monsters.

In all fairness both the ERAY and z06 have decent top end, but it's not enough. The ZR1/ZORA will take care of all that across the spectrum.

Pretty sure most of us don't spend much time north of the 100 MPH mark.

I didn’t say weight slowed it down up top, I said the weight actually helps with traction off the line. The Mac is not NA, it has twin turbos.

Yes, no surprise it’s faster as it has more hp, less aero drag and narrower/lighter wheels tires.

I know, the macs are supposed to win. But right now there's no ZR1 yet so any of the C8 variants have to get some limelight.

When the next variant debuts and arrives, then i believe we're going to see a bunch of wins for corvette. No more getting walked by mclarens lol, the ZR1 will be right there with it or faster.

The ZR1 will need to make more power to offset the extra weight, aero drag and power loss from wider/heavier wheels/tires to be as fast. How much do you think it needs to do that?

It'll be more than the outgoing ZR1 that's for sure. We don't know if it'll be slightly more like the z06 at only +20hp or will be a monstrosity of a car and have mid to upper 800s.

If this is the case, that will solve everyone's issue with power on the big end. But it'll be expensive.

MC cars have a 700+lb advantage over the current C8 models - that's a lot to overcome. 25%+ more power at least, just to hang even. MC's regularly dyno very close to their HP ratings at the wheels, ie the engine is 10-15% underrated. If the 750 is making 750 wheel, it's making 840ish at the crank, which means a Vette would need at least 1050crank HP just to stay even.
A kilo-horsepower car is a lot of horsepowers.

The McLaren costs nearly 3 times as much as the E-Ray. The 750s should run away from the Corvette right at the start and extend that lead. This should not even be close.
Why don't we compare a $120,000 C8 with a $120,000 Porsche or other performance offering. I like a performance car with big ***** low in the rpm band where the engine operates 98% of the time and could really care less about its Ring Time or this U-Turn BS.

Amen.. Son has a dual motor (not plaid) Model s now and he misses his high HP Mustangs; etc. even though the car is a rocket, I always had vettes, 2020 now and ERAY soon, he can drive this one too when he visits for an ICE fix.

Also not sure if this 750s was AWD version and they all come with summer tires. ERAY AWD on AS tires is my personal sweet spot for more of a Swiss army knife setup.. hope to know in June my 2020 has AS tires for flexibility on NE weather as I don't track.

Yeah, I don't track either if you mean the road course stuff but I do enjoy a few trips/year to the drag strip and the E-Ray is absolutely perfect for that duty with AWD. Decent track prep and you'll be extremely consistant with an E-Ray.

Agreed 700lbs is going need 150hp more to over come the weight and maintain same power:weight ratio. Even if the ZR1 makes 150hp which is a tall order at 800+ it still won’t be as fast because of aero drag and rolling resistance is all I’m saying. Same applies to why it took 100-150hp more for a Mustang or Camaro to run with my C5 at the drag strip back in the day. I ran almost identical times (.05) to buddy’s GT500 with over 250hp more at the road course this past weekend and he was on the same compound tire with same overall width 325 square vs 315/335 because of my weight and aero advantage.

750s isn't AWD.

I'm surprised no one else has pointed out that the C8 should be running against an Artura or a GTS, not a 750 / 765. These 2 cars are much closer in cost and purpose to what the E-Ray is.

The ZR1 is not going to fade on the top end. The ZR1 will be 150 HP more, and 100 - 200 lbs heavier than a Z06. The Z06 was 9 MPH behind the Mac, but 9 MPH ahead of the E-ray. If the weight gain is kept to the lower side, the ZR1 should be competitive with that HP gain. Who knows, maybe they'll gear the ZR1 correctly and gain a little there.
