Floated just this idea (albeit with the 4 litre engine) at Silverstone PEC to a number of OPC / Porsche GB guys just before Christmas and was told don't be ridiculous . Maybe this is what the long ongoing wait has all been about Clive

The n/a 4.0L engine used in the Caymans and Boxsters [GTS, GT4 and Spyder] is a derivative of the 911’s turbo engine. Clearly a lot of development time and money was spent on it, so it would make perfect sense for Porsche to use it in the 992.2, especially since the mid engine cars are soon to go electric, thus extending the life of the engine.

As always emissions and fuel economy will be the deciding factors, and I think it’s a no-brainer that some form of hybridisation will be used, most likely with a small motor incorporated into the PDK transmission.

Just my tuppence worth of course.

Hmmm...but to get that amount of torque from an NA, if it is going to happen, will it need electric assistance (in the form of mild hybrid)? Also, I am sure that I read somewhere that Porsche said the 4.0L in the 718s were designed specifically for those models and weren't compatible with the 992 platform. That said, ARC Driver is talking about a 3.6L unit so perhaps a new block?

The announcement about the new 992.2 is next week on the 28th, what do people think will be announced? My money is possibly on a 992.2 GTS using the 4.0L NA engine from the 718 GT4/GTS 4.0/Spyder (which I think is a 911 S engine w/o the turbos and bored out) coupled to some hybridisation to provide about 520bhp overall. Probably 420 coming from the engine and 100 from the electric motor. Probably coupled with updated versions of the Base and S models, both with the same 3.0L twin turbo flat 6 as the previous generation. but with the body, trim and tech improvements of the 992.2. Of course I could be wrong and they could announce a more aggressive option around the Turbo but that would need 850bhp plus and that's probably a 4.0L twin turbo coupled with a larger electric motor and battery. I would have thought the GTS option is more likely, provides more of a splash and the naturally aspirated engine would make the model more attractive even for those not so keen on hybrids. Plus the GTS option would be consistent with the Cayman/Boxster approach with the 4.0L options. Of course this could all be completely wrong!

Just been announced here. Looks like I didn't get it right, they didn't go for a 4.0l NA engine, but a new 3.6l turbo together with an electric motor making a total of 534hp. This is low when you consider the size of the engine (3.0l to 3.6l), increased turbo boost pressure (18psi to 26psi) and 54hp from the electric motor. The answer is maintaining the ideal fuel/air mixture and this is explained in a good technical article here.
