I expect GT4 PDK vs Chevy Z51 DCT, quarter mile timed and trap speeds will be near identical, but we’ll see when the tests come out.

On paper, the Chevy suspension is more advanced, but in general Porsche has a history of making “inferior” layouts and designs outperform their “superior” competitors. The significantly lower weight would also be beneficial to the GT4.

While the tall second gear of the manual GT4 would hurt slow corners, I expect the PDK version with better gear ratio spacing to not be hurt by the torque deficit - the Chevy may pull like a school bus at 4500 RPM, while a PDK GT4 might do the same corner with less torque but at 5500 RPM, and with less mass to lug.

My guess would be roughly identical track performance between the PDK GT4 and DCT C8 Z51 Vette.

I fully respect the C8 Vette - it looks like a solid performer again at a substantially lower cost than a Porsche. Building a car that can match the GT4 is no small feat, and of course future Z06 and ZR1 variants should comfortably beat it.

In Canada, I’d expect a Z51 LT3 C8 Vette with FE4 suspension (guess based on C7 Canadian pricing and C8 price bump: $94k CAD) to be around 3/4 the price of a new GT4 with leather interior ($125k CAD reasonably optioned). For a 3 year period of ownership, the GT4 would probably still depreciate less (dollars) than the equivalent Vette.

A future C8 Z06 should beat the 718 GT4 for less money, but that has always been the case for Chevy vs Porsche at equal prices.

The rear mid engine design should help the new Corvette better put down its power at low speeds, the interior is a step forward in quality, and it continues the excellent price per dollar Corvettes have always had. However, at least in Canada, when considering equivalent specs (not the $60k USD base car that’s probably $70k CAD), and historical depreciation rates, Porsche is probably cheaper to own, even after considering investing the price difference in a mutual fund. In the US, Corvette might be slightly cheaper after considering investing the price difference.

For the same cost of ownership, and comparable straight line performance, would you rather have a lightweight and semi-rare Porsche, or a large, heavy, and rather common Corvette? I’d take the Porsche, and that’s why I’m buying a 718 Spyder.

Would I pick a NEW C8 over a used 996 GT3 for even $? Not so sure. Not even sure that a new DCT 3600lb 500hp C8 would be faster than a 15yr old manual 3100lb 380hp 6gt3 in good hands on any track either. Not even getting into how much more fun driving one would be over the other. Or depreciation...

• Standard FE3 Performance Suspension
• Larger 345 mm front and 350 mm rear brake rotors
• Extra cooling with additional rear-mounted third radiator
• Electronic Limited-Slip Differential
• Larger rear spoiler provides up to 400 lbs. of downforce
• Performance exhaust results in 495 HP

for about $8k. That is still under $70k, and still an incredible deal.

Now there may not be many base C8s around when its released, but you can order one direct from factory for the $60k price. So yes, it is funny people are comparing base C8 vettes to $300k super cars.

Would never consider a 996.2 GT3 again. As nice as the 997 was the cost of replacing a Mezger engine == no go.

A straightforward question - why should I trade my 720S or 991 II 3RS for a C8?

Better or worse is highly subjective, I do like the P dealer treatment, but you pay for it. Your average GM dealer can be cringeworthy and finding a good service department for a C8 will probably be worth the extra drive. That said given the multitude of GM dealers vs Porsche that’s probably a wash.
