718 GT4?
The Spyder spotted on the Autobahn was also most likely 6-cylinder - it was just difficult to tell because the RPMs were so low. An audio specialist did analysis of the frequencies though and thought 6-cyl. Analysis here:

Jeff, who did the audio analysis of the Spyder while it was on the Autobahn, and determined it was likely a 6-cylinder BEFORE the Nurburgring videos came out is still of the opinion that it is probably the NA 4.0L H6 after listening to the Nurburgring audio: https://www.porscheclubgb.com/forum/FindPost/996271
Edit: He does acknowledge that it Could be the TT H6 however.

My original guess was that porsche would follow the GT / Spyder protocol established with the first car. Specifically - Install the carrera motor in the car with a slightly different tune.
Those "fit" dudes were wrong. Just remember the GT4 chassis was different from the Cayman S / GTS.
This has become very interesting. Whoopsy seems to be super sure and he has super awesome cleaning ladies.
So maybe porsche will have the spyder be 3.0T and the GT4 be a 4.0? I still doubt that. The 911 boys would cry all day long if they put an engine that special in the GT4.
Fingers crossed they do. With that said, if the new GT4 is 3.0T I may spec it out and try it before getting my deposit back. The current GT4 engine is just so damn great sounding.

If I was planning the 982 GT4 with an eye to GT4 racing, I'd fit the 3.0L Turbo 992 engine into "the" new generation platform. This chimes with Rennlister Shockwave's post re meeting in Germany and the need to have a competitive race car. It might also allow the adoption of a non-strut rear suspension....
The rear suspension is something that porsche do not want to match to the performance of the 911....

Turbo 6 !!! I'd bet money that's the 3.0T.

Id take that bet.
You need my paypal account now or later?

Check out the Porsche PET diagram of the 3.0L Carrera turbo motor and compare it to the PET diagram of the 981 3.8L and you will see why it will not fit.... (it is too long)

I can see the logical reasons for not going turbo but I don't see how the actual recorded sound, on several occasions now, squares with an NA engine. It just does _not_ sound like the 3.8 or 4.0 H6 NA engines that we know. Like, at all. The particulate filter is a wildcard here but I would imagine that whatever they have been testing extensively on the road and now the track is what they intend to produce, and a month ago Preuninger sounded to me like they were not at all ready with the filter solution for the big NA engine.
What we have seen (heard) in the real world now has to carry a bit more weight than hearsay or logical deductions based on educated guesses. It does not rule out the NA by any means, but guessing between the two I'd have to go with what it sounds like.
