The 718 GT4 might be arriving sooner than you think!
Discussion
They don’t seem to be hedging that much. The following excerpt seems quite committed to an opinion:
“In this case we suspect that six-cylinders will make a welcome return to a mid-ship Porsche. In addition to this, the likelihood of it being the new turbocharged unit from the current 911 seems small, and a process of elimination leaves us at the likely conclusion of the next GT4 featuring the scintillating 4-litre flat-six, as used in the current 911 GT3.‘

Meanwhile..... Over on Rennlist.... A chap claims to have bumped into the new GT4 (+driver) at a shopping mall situated near to a local Porsche testing facility..... He has pics as well— very much like the black mules we’ve seen running around, but with what appears to be a GTS front bumper..... The driver forbid him from taking videos, but did rev the engine from idle..... Apparently it sounded 100% like a N/A car, with no evidence of “turbo spool”.... 
I asked if he got a peek inside the cockpit, and he reports a stick shift, but unable to see the red-line.... (darn..!!)
Make of it as you will.....

Having originally been rather skeptical of the GT3 engine finding it's way into the GT4 I now believe it would make a lot of sense. Porsche has been outgunnged in GT4 racing by Mercedes and Audi who - contrary to the whole idea of the class - have produced detuned GT3 cars instead of building a proper "affordable" GT4. If Porsche wants to be competitive, they need to join into the arms race
An Rennlist poster who was at Weissach yesterday posted the following just after the "shopping mall" pics. I've added some interpretation to his comments, you have to read between the lines:
My phone was away from me for like 6 hours, but that's pretty much the rumoured car. [Flat six engine]
The other half of the twin will the same but the the cloth top like old ones. [Spyder and GT4 identical, bar the 981 Spyder roof]
Engine will be bespoke to the car(s) for a while. The race car version which I am most interested is going to be a evolution but will be competitive with competition from the cheater cars from McLaren and AMG. Without the extra weight of useless stuff for the class like snails. [New 4.0ltr engine in the GT4/Spyder will be used in other cars in the future. No turbos in the GT4 race cars either]
The thing that was suppose to be on top of them is bonkers. I will totally take it over a GT3 without even thinking. But it is neither confirmed nor denied. The car I saw was just a figment of my imagination apparently. [GT4RS mule]
Cars will also follow the current transmission rules. Cars also don't need someone to press the brakes for torquing. [Manual and PDK options for the GT4, PDK only for the RS if they produce it]
There was something sitting there without a hard top, but it was completely ignored as the car next to it is the Youtube car, I already placed an order directly with Weissach, it is the ultimate widow maker, good luck to my wife. I suggested a mandatory training session with purchase. They also think its' a good idea just so their customers won't be dying left and right. [911 Speedster, the "GT3 convertible"]
The same guy also posted elsewhere:
As for the title of this tread (Re: Porsche Cayman GT4 RS), I saw the car, it isn't confirmed or denied. All based on market acceptance. But I can say it is a bad assed car, pretty much the very best out of Weissach for a since a long while, and that already included the GT2 RS. It's not about the ultimate fastest lap time, but more about the car itself.

Genuine query to those with more knowledge of racing series than myself, but if the clubsport car is NA and that races in various FIA GT4 series, doesn't the production car have to be likewise for homologation purposes?
Or is there different rules for GT4 hologation and/or with clubsport cars being for private use (sort of trackday plus)?
Edited to add that I'm basing the NA element of the race/clubsport car on the noise recorded during recent test filming at Monza

I'd say it's game over, yes. The persistent rumours are the ones that appear to be true:
- Spyder and GT4 are coming
- They're identical bar the roof
- 4.0ltr flat six NA engine
- A GT4RS mule exists
- PDK this time around? I would say that seems likely.
- BHP? Somewhere around 410bhp would be about right.
- Will the GT4 RS make production? As has been the case for a while, it seems even Porsche don't know that yet!

Given there is balance of performance, why does Porsche necessarily need to build a faster car just to join the arms race? It's more a question of lobbying to get the more favourable adjustment than joining the arms race surely. Look at cars like the Mclaren 570 GT4, they are restricted by well over 100hp and carrying 100+kg of ballast.I appreciate most may have already heard this, and that all of the below is with reference to the Spyder, but the sound in this video definitely sounds 6 cyl and not F4 to me:
https://youtu.be/GZ_b3fF8CeE
I think it’s going to be an NA F6, and 4.0L as per most rumours.
It sounds slightly deeper than the 981 Spyder’s 3.8. Sounds a little more GT3 to me as well.
Personally I prefer the brighter rasp of the 981 Boxster Spyder to the GT3’s blare, but realise I may be alone here.
Smaller capacity can sometimes sound a little more screamy and exciting to my ears.
It doesn’t sound like a turbo to me, but the recording sounds far away, perhaps meaning the video is a bit zoomed in.
The only thing remotely suggesting turbo for me is the road/tyre noise masking the exhaust note, but I think it is just the nature of the recording.
On balance if it’s a F6 NA I’ll trade in to this if I can get a slot, but for me the bigger question now is whether anything will be done with the gearing.
I suspect not (for both emissions and pegging it correctly within the range!), although PDK will be shorter geared of course (but I’ll be going manual Spyder again if ordering).
Porsche have mostly had longer gearing than say the Ferrari V8s or Hurracan.
With gearing as short as say a Ferrari 458, the argument for a paddle shift box perhaps becomes a little stronger for the average driver (those cars hammer through the gears so quickly) even though I am a manual person through and through.
On gearing - shorter final drives are now available for 981 models from AutoQuest, along with a further modification of a longer 6th gear to compensate for the shorter gearing when cruising . I’d imagine only the Americans with their mod-happy culture will be brave enough to proceed for now:

Centre steering feel and gearing are the 2 main improvements I would like to see moving on from the 981 Spyder.

I agree. Tyre noise is surprisingly significant: you only need to hear a Tesla passing at the speed limit to notice that it isn't noticeably quieter than an ICE car off throttle.The only thing remotely suggesting turbo for me is the road/tyre noise masking the exhaust note, but I think it is just the nature of the recording..
Pointing a camera with poor sound recording equipment at a car at the distance is not going to give you any information worthy of the pages of discussion it seems to be generating.

This is the only clip I’ve seen that sounds a bit 4 cyl. Just sounds a bit odd to me, however the other clips came after so am inclined to ignore it.It could be dubbed for all we know (highly unlikely, I know). Either way, it sounds like a different engine to that in the later clips to my ears.
The only other get-out is that the revs are quite low, so less of the full character is revealed:

You’re right - OT but while we’re on it, I was shocked at how little the electric “quiet” factor of the Tesla model S mattered at motorway speeds - it felt no quieter than a good luxo barge with a smooth engine!Tyre roar is definitely very significant in that Spyder video. Hopefully it has a raucous enough note in reality!
