Sorry if a repost.

Well, the first link you posted lists the second link you posted as their source. This is how so many rumors get perpetuated. You get one "source" making a claim, then you get countless other internet articles citing the same exact original source all to generate their own clicks...

Dude, Everything posted on this forum is a rumor until it is confirmed by GM. That is the purpose of the form, it is for discussion. I simply posted something to share with others and did not offer any opinions one way or another. This is just the most recent article.

BTW, it's not just 2 sources there are plenty more.

A Dodge land yacht muscle car might suit you better. A C8Z at 617hp, lighter weight, better suspension, closer-ratio gearing, and better aero is more than enough to set record or near-record lap times. Look at the new Porsche GT3 as just one example (502-hp/346-lb-ft). These aren't designed to be drag cars.

Don't forget there are still other higher HP C8 variants coming.

I gotcha. I understand. And yes, both of those articles essentially link back to the Wheels publication.

My point is, there are not "multiple stories confirming 617 HP" as you state in the initial post. There is one source making this claim, and then multiple other sites regurgitating the same info...

And the 2nd link uses Wheels as their source. I see what you mean. Just a big circle of rumors.

617hp NA would be a winner for me.

I hope it is lighter weight, but the base C8 already weighs more than the C7 Z06 weighed, so I don't see how possible it is for a C8 Z06 to weigh less than even a base C8 with bigger fenders, a physically bigger engine, and added aero. Yes, it could be done, but the price would put it out of Chevy's target demographic IMO.

Easy (and not terribly expensive, except for the CF wheels) things that realistically could be done on a lightweight/track-focused model (Z06, Z06 'track edition', or some other model):
  • Lithium-Ion battery instead of lead-acid starter battery (see: Antigravity batteries, vendor on this forum)
  • Thin all the glass like they did on the C5 Z06. Possibly make the rear engine lid out of Lexan (like on a lot of supercars) instead of glass to save even more weight.
  • Titanium exhaust like they did on the C5 Z06
  • As an option, ditch all the features/luxuries to save weight- just have a stereo, heating,and cooling. Remove leather from all coverings. Remove sound deadening material. Think Ferrari F40-level minimalism.
  • Lighter weight seats.
  • Work with Tremec to lighten the heavy DCT where possible. Use of aluminum and titanium where possible.
  • Carbon Fiber Wheels option (option, not standard, for those that want them and for GM bragging rights on lap times with the car)
This would be the modern version of the C5 Z06 and C6 Z06, or "RS" model 911s.

You won't shed hundreds of pounds but you'll shed a LOT, which WILL translate to amazing performance results. It's not about weighing less than some other car; it's about weighing less than it would otherwise weigh WITHOUT these measures.

All this originates from a Wheels magazine article (based out of Australia) authored by Motortrend editor Angus MacKenzie. I’m surprised it hasn’t been posted yet. Touches on all future variants, and has some snazzy renders of the ZR1. The widebody proportions are going to do wonders for the rear end design of the C8 IMO.

The LiIon battery is a great suggestion. I agree that is a real option for significant weight reduction.

I think the C5 maybe saved ~5 pounds total with glass weight reduction front and rear vs the base. (I cant remember though if that was also due to the smaller size rear glass vs the coupe's hatch.)

Ti exhaust is expensive, but would save a few pounds.

I can see them doing some things, but I don't see how they would do enough to offset the increased weight of the aforementioned things I said. I think best case scenario is they maybe get close to the base C8, but I'd be skeptical even of that. Remember that the C5 Z06 was not a widebody, so it made it easier for it to save weight vs the base model. Plus, the LS6 engine weighed essentially the same as on the base LS1.

We only have this kind of speculation though at this point. I think every horse in this stable, if not dead already from continuous beatings, is in serious threat of expiration. We need data from GM.

To repeat previous discussions I would really like to see a track variant founded on light weight, more grip, NA power, and tactile engagement. I think GM will go for the most ROI and stick to their brand as a driving appliance company that can build a fast car (rather than a racing company that can make a daily driver like Porsche/Ferrari/Lamborghini). So I think they’ll go for what will sell the most units while minimizing cost, which is to slap cheaper power/aero on to serve the majority lawn chair racer and call it a day.

Been there, done that. Some of us will never see a track, so street worthy torque is more important to me than buzzing an engine to 8k on the straights. But hey,, each to there own. One can never have too much horsepower..

620 NA horsepower, bigger tires, knock off 200 lbs with carbon fiber, lightning fast DCT, and that thing will shred almost every other car.

Cant believe any numbers out of MotorTrend’s mouth, but the LT4 probably made about the same once it was hot and timing pulled.

Big credit for admitting that you won't go to the track, not everybody needs to go there to enjoy a car.

But if all you want is stoplight-to-stoplight torque...why would you not buy electric? Seems like the E-Ray is the car to get for those folks. No gas powered car short of exotics (or 911 Turbo) is going touch what you can get out of a Tesla or Taycan.

Silly logic. Some of us will never see a drag strip either. Does that mean the base C8 shouldn't have had impressive acceleration numbers?

Not going to the track doesn't stop one from taking spirited/aggressive drives on winding roads with lots of turns. And a track-oriented car makes driving on these types of roads much more enjoyable and engaging. To disagree would mean you don't think cars like the C5Z, C6Z, and Porsche GT cars like the GT3 aren't a blast to drive on winding public roads.

Because its the wrong badge. They need everyone to see that Z06 badge.
