LOL so you are saying Porsche can’t figure out how to make more power from 3.6L motor vs 3.8 in a 10yr period?! I think the new motor will make 450-470 on its own. The battery will add some hp but mostly be there for low end torque.

I’m pretty confident they know what they are doing and 483hp with mild hybrid is very realistic.

The 3.6L NA motor makes no sense. If this was the case the new 3.6 would be better then the current 4.0 in GT3 etc.
Maybe, but that would be one expensive engine.

I believe the article is not correct and the engines will be 3.6 turbo with hybrid.

Obviously we don’t know if the 3.6 NA is real but to say that Porsche can’t develop NA engine making around 480hp for 2025MY when the 991.1 had 430hp NA engine for 2015MY is what I don’t get?!

The current 4.0 in GT3 makes over 500hp and revs higher, its a motorsport engine. Just because #s look similar on paper doesn’t mean engines behave the same way. Also - If you read the article the next gen GT3 will have a new engine.

Makes sense to meet future emissions requirements. It's happening...

Manufacturers are simply forced to abide by CAFE guidelines/regulations. It is what it is…

Of course they know what they are doing, the question is if the article is accurate. Look at what other naturally aspirated, non-exotic, engines make. The best example is the 4.0 in the gts boxer and that would be your absolute best case on a 3.6l engine. Remember the saying “there is no replacement for displacement”…that was the gospel before turbos came around, there is no easy way to get additional horsepower from an NA engine.

Then do some basic math and and figure out how much current the 48v battery would have to output to deliver 80 horsepower.

Is the article indicating there will be two types of GTS - one a completely naturally aspirated and another a hybrid version? Or just a singular GTS option that is hybrid ?

Only 1 GTS, a non-turbo mild hybrid

Again, the article was written in an almost incomprehensible manner but it said the 992.2 line up as follows:

Carrera: Turbo 3.0 390hp
Carrera S: Turbo 3.0 48V mild hybrid 454hp
Carrera GTS: 3.6 48V mild hybrid 483hp
New T-HEV: Turbo 3.0 full hybrid 528hp
Turbo: Turbo 3.6 48V mild hybrid no hp mentioned
Turbo S: Turbo 3.6 48V mild hybrid no hp mentioned
GT3: 4.0 48V mild hybrid no hp mentioned (but switch to 3.6 mild hybrid in 2027)
GT2 RS: Turbo 3.0 T-HEV 800hp

Who knows if the article is correct or not, but it does state that the new 3.6L NA will ultimately replace the 4.0L NA engine in the GT3, and it is hard to imagine that the new GT3 engine would have less power than its current 4.0L engine. In that case, the new 3.6L motor (at least in GT3 tune) would be better than the current 4.0L in the GT3, and the 3.6L NA motor in the GTS would appear to be a detuned version of the 3.6L motor in the upcoming GT3. Also, a number of people have commented on the article's reference to the "variable-vane VTCI engine" as meaning the engine is turbocharged and not NA. Again, who knows what is accurate or not, but its entirely possible that the new engine will employ some form of variable intake technology and that is what the "variable-vane VTCI" is in reference to. Another cutting edge, high-output NA engine, the LT6 engine in the C8 Z06, uses variable intake technology to achieve 110% volumetric efficiency without a supercharger or turbos. I suspect the 413lb ft of torque figure mentioned in the article includes the torque output from the ISG that is presumably used in the mild-hybrid system.

Curious to understand why you think so
It appears many of these proposed changes will be implemented to work around the emission regs, meaning compromises of some sort, be it hybrid technology or other factors.
The 992.1, in all of its forms, IMHO still adheres to the classic sports car model whether PDK or Manual ( Personal Choice ).
The frenetic nature of the C&D article hints at some of the hoops Porsche is now trying to jump through with this next generation.
We live in an age where technology can supplant many of the variables that made the 911 such a desirable vehicle in the first place.
The 992 (1) to me seems to straddle that line between analog and anodyne almost perfectly, which is why I think it will occupy the "forever vehicle" spot in many garages for years to come.

Disappointed in C & D editors and editorial process that the article was published at all until all its convoluted mess was cleaned up. It hurts C & D credibility.

There seems to be some confusion in this article...variable-vane VTCI sounds like a turbocharged engine. Also, the horsepower/tq figures quoted for for the THEV system are 478/475 yet when they get into specifics about the Base/S/GTS the numbers are different. It seems to me that this article has combined a bunch of rumors from different sources and combined them.
And I think whomever wrote that article needs to come out with a better article.

their credibility departed long ago. Bring on AI for better articles.

So a tuned Carrera S will be faster than a GTS. Nice...

Yes, but that same thing is true today.
