Listen I love Porsche but credits where it's due. The corvette c8 stingray is as fast as a Porsche 992 Carrera S both in a dragrace and on a track. Check the comparison here on fastestlaps if you don't believe it. It even bested the 992 on the Nurburgring. It costs 60K vs Porsche 115K. The quality is good, the performances are amazing. Porsche's quality is slightly better, and it has a slightly better steering/gearbox. However the Vette is more comfortable and it's a targa. Best value for money? The Vette. Best car overall? Don't know, they are pretty close.
Corvette c8 Z06 vs Porsche Turbo S 992. Both will have around 650hp, but the Vette will be more track-focused and naturally aspirated. Also, it will cost 85K vs Porsche 250K. It will beat the Turbo S on a track and it will match it on a straight line. Even the old c7 Z06 bested the 991.2 Turbo S on a track while costing a third of the price. The Porsche could only win on a straight line. So yes, the c8 Z06 will definitely be faster than the 992 Turbo S on a track, while the Porsche will be the best daily driver. But the Vette will be BY FAR the best bargain.
Then things will get even worse for Porsche. The ZR1 will have about 850hp, which is likely more power than the future GT2RS and now that the Vette is mid-engine, the ZR1 might actually beat it, on track and on a dragrace, while costing half the price. The only way to keep up with an 850hp ZR1 will be to extract at least 780hp from the B6, make the car really light and use cup2R tyres.
Finally the ZORA will have a hybrid system producing around 1000hp. It is rumoured that Porsche is working on a hybrid 911 too, so we will se how Porsche will answer.
But the point is: the new Vette will match every 992 variant on a dragrace and on a track and it will do so while costing half the price. And despite all of this, the quality of the materials will be good nonetheless and so will be the steering/gearbox. Porsche might have slightly better steering and gearbox but the truth is that they are not worth all that money. Porsche just wants you to pay for the brand. Those like you who claim the Vettes are "low quality junk" are either misinformed or delusional or quite simply Corvette haters...
