Bumping up against physics

Based on some of the performance metrics, it would appear the 992S is getting pretty close to the GT cars, at least the ones still naturally aspirated. Makes me wonder how much room Porsche has left to improve on already ridiculously capable NA flat 6 sports cars. I would think at some point in time, physics and the limitations of tires, suspension components and ICE designs will eventually reach a point were meaningful improvement is impossible.
I ask myself, then what? Will the overall "feel" of the car become the primary target for each new model as opposed to all out performance. Or perhaps at that point everything will be hybrid or electric.

^ Make them lighter.

It really seems that we’re reaching the limit on conventional car designs with ICE engines, chassis design and materials used for tires, brakes, chassis etc. Unless we see a major evolutionary technology advancement in tire compounds (specialized multi compounds), brake compounds (carbon ceramic), weight saving materials (carbon fiber), or how power is achieved (electric engines) delivered, stored and replaced (batteries), we really do seem to be hitting a ceiling on the ICE vehicle.

Traction is the limit for initial acceleration.. but with more HP cars will go 100-200 much faster and have higher top speeds.

Yeah but that's the point, the performance metrics of many of these "road" cars have gotten so good that continuing this rate of improvement seems difficult if not impossible given current technology. That's not to say improvements will not continue, just that at some point the limitations of physics will begin to set some hard limits on what is possible

There’s really nothing stopping Porsche from making a 918 level car at 911 prices.

We have a way to go before physics is the limit. Engineering higher engine outputs using a NA system will be a challenge. The march of progress is sure impressive!

As we shift further toward electrification the importance of adding lightness will only increase.

The limits for IC engines, whether N.A. or forced induction are regulatory not technological.

I thought we were talking about street cars like the 992 not GT3s.
In any case yes: regulations. Even in - *gasp* - racing
