If it has a GT3 engine then it will cost GT3 money, which is fine by me as it's less likely to depreciate my GT4.

I think it’ll cost significantly less than a GT3, whether or not it has a GT3 engine.

When the 981 GT4 came with a Carrera S engine, it still cost less than a Carrera S ($85k vs. $99k)

981 GT4 'Carrera S' engine was marketing, lol... the engine is based up on the 981 GTS 3.4 core... with increased capacity

actually you can say that about all of the engines these days. The 4.0 in the 982 is based on the 2.5l from the 718 S

Now thats a stretch!

You are missing the point, the actual engine from the Carrera S was not rotated 180 degrees and put into the 981 GT4...

As for some family similarities between the 4 cylinder engines and the 9A2 EVO 4.0l, they are only that... The other thing that drives me nuts when somebody says they bored out the 911 3.0l engine to make the 4.0l, again a massive misrepresentation of the actual situation, the engine block design is similar but it is cast to support the larger displacement and midengine orientation from the start.

ExMB

Actually that is incorrect. It is a combo of the parts bin between the 911 3.0 AND the 2.5 of the 718 with some additional drilling.

guess depends on what your definition of ‘based’ means… to me this sums it up. They were designed from the start to be a family of engines that can be flexibly interchanged across platforms.

porsches own words;

One thing that all members of the boxer family have in common is their cylinder spacing: invariably 118 millimeters. Within the cylinders, pistons with diameters of 91 and 102 millimeters do their duty. More precisely: either 76.4 millimeters up and down or 81.5, depending on the crankshaft. Together with the number of cylinders, this results in five different displacements and nine power levels in the 718 and 911 model lines. With a pool of identical parts that are used without modification in all model lines, as well as components with similar design principles, the result is a wealth of synergies in the fundamental engine design toolbox. This enables developers to concentrate on the individual character of the engine’s periphery—for instance, the intake duct and exhaust system. The result is typical Porsche: because all boxer engines bear the same genes and despite their different characters, they’re all equally efficient, emotional, and driven to perform.

Sure as long as we agree it is the "design philosophy" that is used across platforms not the engine themselves, regarding the bolded, the engines don't interchange...

Late to the game, but I'm an interested and have expressed my interest to my dealer. Based on the single page of posts above, I assume we're waiting for November to hear anything? It would be very odd for them to release a car like this for the LA Auto Show, but who knows, it seems like this has been teased for far too long and is overdue for a release now.

If the bhp is 475-480+ and the engine is super durable/reliable, does it really matter if it's a GT3 engine or a 718 engine? The displacement and bore x stroke are identical as I'm sure the power curve would be similar regardless of what its "origins" are or how close to "motorsport derived" something is..so long that its bullet-proof on the track and it produces the advertised power is really all that matters ultimately. Plenty of examples of "motorsport derived" engines that blow up more than average (eg BMW S54/65/85, Ford FPC Voodoo, etc). Even the .2 991 RS track record isn't pristine.

Anybody hearing what the going ADM is likely to be on the 4RS?

Archimedes

But you're forgetting about the fact that when the car is six years old and has 372 miles on it and the owner goes to sell it, he needs to be able to use the word 'Motorsport' in his for sale ad. So, yeah, it is a big deal.
