Damn. Love it. I have never wanted or respected a Corvette this much until the C8 arrived. GM is just killing it here.

Center quad pipes and side intakes more like the Stingray rather than the Z06/ZR1, it sure looks like it.

Rumour has it that on the Grand Sport, you will be able to choose between a central exhaust or side exhausts like on the Stingray.

Rumour: Unveiling of the C8 Grand Sport and Grand Sport X in April. The X version of the Grand Sport will replace the E-Ray with a hybrid system and AWD.

The E-Ray is a sales dud in the otherwise world-beating lineup in either pricing or sheer performance. Nice save by GM/Corvette team to avoid it stagnating on the market.

I guess people are afraid of the battery.

AFAIK there’s no hybrid sportscar that sells well.

AFAIK there’s no hybrid sportscar that sells well.

Yet none of the major manufacturers seem to get the memo from nearly every enthusiast or are too far along in R&D activities to pivot. They are a maintenance liabilities to keep longer term, and the it mixed power outputs (even when seamless) takes away from the visceral, "no replacement for displacement" performance people are longing for.

The second-hand market is not for the weak across the board, while the simpler previous models are appreciating. Even the Revuelto is not looking like a car to hold long term like it's predecessors, which is something I did not have in my cards.

 

[Swissbob]

Well said. I agree with you on every aspect. You absolutely nailed it.

Same goes with the screens.
As we can see from the AMG GT XX Thread, there are screens everywhere although people are getting annoyed from them.

Leaks Out of GM Dealer Meetings Say Grand Sport, Grand Sport X on the Way for 2027!
Corvetteblogger

As we discussed yesterday, GM is holding a series of meetings at its annual automotive conference in Las Vegas and we’ve been hoping to hear some details coming about the future of the C8 Corvette line-up. This morning I see that our wishes may have come true!


A post from ZR1_M7 on Instagram appears to be backing up the rumors we’ve heard from our insiders which is that both the Grand Sport and a Grand Sport X (formerly known as the E-Ray) will be introduced for the 2027 model year. He also puts out an unconfirmed rating of 720 HP for the Grand Sport X, which would feature the new LS6 V8 engine paired with the E-Ray’s front electric motor.

Check out that post here (and let’s credit Brink of Speed for the awesome photo!):

Let’s take a look at that horsepower number. If that’s the case and the Grand Sport X comes in at 720 HP, we can then back into two figures for the GEN6 LS6. If the GSX is getting the same electric motor as the Corvette ZR1X which is rated at 186 HP, that would mean the LS6 would come in at 534 HP. That falls within the estimates of 525-550 HP in our reader poll. However, if the Grand Sport X retains the E-Ray’s 160-hp electric motor, that means even more horsepower from the LS6 at 560 HP! Either way, it’s a win/win for the Grand Sport and the Grand Sport X, as well as the Stingray which is rumored to get the new LS6 as well.

So my information was correct, thanks for share @asrapid1
