My guess is in the 480 range. Itís on par with historic increases and the new 992, itís main competition.

My current thinking is weíll see a third model year refresh with a 4.2 DOHC TT V8 with a significant bump in power and efficiency in the Stingray, and the 5.5 TT DOHC V8 next year in the Z06 (alongside the C8R).

The ZR1 would then get the 5.5 along with hybrid electric motor assisted AWD.

500 or more hp is laughable at $60k.

give GM a chance to work out the bugs for a year or two

Hardly unexpected news, GM needs an affordable value-centric Corvette to sell the numbers that make this product profitable for GM.

Iím done with pushrods myself, I find them pretty joyless in day to day driving if Iím being honest.

Definitely looking forward to the performance variants of this car which Iím assuming will dispose of the LT in favor of a more responsive, modern turbo motor.

As a low budget potential used buyer someday, this is good news.

Default How much power do you need?

I was in awe of the 400+ HP of the C5 Z06 and then soon enough we had 400+ standard. Now itís 455HP Iím a base model and folks want more. If the car weighs less, handles better, and costs similar then I would be fine with the same 455HP available. Some folks are wanting 500+ in the base model. 475HP would be a step up but still not enough for folks. Does the power really matter if they can make up for not increasing it?

Default Grand sport is 460 with no cai and long exhaust on FE

I am sure folks are sharper than me on ways to get more hp with a few small mods Chevy could do to get to 500hp fairly easy with base engine? A CAI would add? Short pipes in ME with our nice flowing exhaust would add?

A slight tune from existing 2019 and above can get you to 500?

Feels like 500hp is a key Marketing number after having 460 since 2014!

My rule is not to buy a car that is not as fast as the one I have. So even though I have a deposit down on a C8 Iím not convinced yet I will bite until they have one that at least can beat a 2.9 0 to 60 time. I came from a 911 S with a dual clutch transmission and Iím totally convinced itís a big advancement over an old manual transmission but people will argue the manual Is more fun to drive. It will be good that the Corvette is joining the ranks of other supercars with only DCT tuning and testing. I am hoping the weight distribution will help with rear wheel traction and improve 0 to 60 times in the Corvette. I might have to wait till the Z06 version comes out and I hope that is not too long into the production. The reason I put a deposit down was because of all the mystery and if it turns out to be really great I want to be able to get one sooner rather than later. I am also hoping that the convertible version will look good with the top up. I love driving a convertible but I like the look of the coupe so much better that I had to Buy it. I do remove the top on the car quite often but itís not quite as good as a convertible. For me, 0 to 60 time in 2.7 , and a convertible that looks great with the top up ,and I would be all in.

I found the C7 engine to be boring. No real reason to take it over 3500 rpm. Just noise. All the power and torque is down the rev range.

I agree and the C7 GS should have been 480-520. So this is where they might naturally start off with the C8, but they probably will start on the low end.

I suspect any lack of response is more how GM tuned the engine throttle mapping (emissions?) than inherent in the Pushrod design. Large displacement naturally aspirated engines would tend to be more responsive than a turbo motor that has to build boost, even with lag reducing technology. But I totally respect your opinion and preferences! It sounds like the performance models will be turbo, so hopefully you'll have an engine option that you enjoy!

Lol at 3500 rpm the LT1 makes about 250 hp according to the SAE plots GM released. So an extra 200 hp would be the reason to go past 3500.

People focus too much on horsepower numbers. If they can reduce the weight over the C7 and improve the handling I wouldn’t care if it was 450-470hp/tq.

I'm not impressed with the intake ducting on the C7 and some other things about the setup. The hood vent is way cool though. Seems it should be easy to make 500 or more with pushrod 377 cube NA engine and still be a mainstream production. Could be they are planning to hold back a bit for a few years later I will be disappointed if they do, but hey, maybe I should be used to disappointment.

Sounds like torque management may have been wreaking havoc, especially if you were running an auto. My M7 in 3rd gear does quite well above 3500, although I admit I've only been able to get on the track once to truly experience that. Hope to change that in the future!

Have a good one,
Mike
