I had thought the same as @JCviggen, but actually the point you make @Chris3963 is very valid.

Have you mentioned pricing? I keep seeing 125-130k, wondering if you know more?

Also is there a chance of a Weissach package on this car? Considering it's like a what, 30k+ option on the GT2/3 RS?

There is a video of gtr4s on the ring with a very high revving engine... those last moments before the shift up sound very GT3ish.

Everyone said the regular GT4 was going to have a GT3 9k rpm engine.

Im guessing the current 4.0 revving at 8500 RPM. Porsche has already proven they want to keep the 9k RPM engine special / bespoke for GT3. Makes sense.

JCviggen

That's certainly true, I agree.

There's more to the difference than just the exhaust though. As you mentioned, putting a GT3 exhaust on a Cayman doesn't transform the sound into a GT3. Not even nearly. The howl just isn't there, and there's a particular edgy subtlety to the GT engine sound that is altogether absent in the mere mortal engines. It's not just the exhaust, you get it from the intake side as well when the car's coming towards you. Ehresmann in Germany has the 4.0 DGG in his GT4-R and it sounds noticeably different from the 3.8 (and then 4.2) MA103 it ran initially. Not exactly like a GT3 either, admittedly.

There's a few different videos of the GT4 RS mules on YouTube, not all featuring the same car, the latest one certainly had the loudest and clearest sounding car. Maybe it was the non-EU version. It sounds different enough from the regular GT4 to make me wonder what's going on exactly, not ruling out it has the GT engine or some semi GT version where they borrowed some bits but not the entire thing 1:1.

I would dismiss anything anyone heard from their dealer however. Doesn't matter how good of a customer you are, the fact is that dealers simply aren't told most of the super secret specifics at all until very close to the end. We saw this previously with many people being told by dealers that the GT4 had a 4.0 "detuned GT3 engine". Which was a baseless assertion only inspired by the fact that it was going to be a 4.0 and the only such engine that existed at the time was the DGG.

I've had several conversations with the Porsche (GT) people as a journalist, and anyone outside of management and engineering simply isn't allowed to know **** until they want it to become public. They go after leaks very heavily, even innocent ones like a picture they sent to a dealer right before launch. It gets tracked down and the other side will be in trouble.

I believe it will be one of two options. An upgrade of the present engine to 440+ hp with a different exhaust as this is easily attainable and was always in the plans for their engine hierarchy for the new 4.0L. Or maybe we will be pleasantly surprised with some titanium internals, an 8500 rpm, and maybe 475 hp as some have said. Doubt they would give a Cayman 9k rpm, and why put in a detuned GT3 motor. That just makes no sense after all the money they spent on the 9A2 motor, let alone the compatibility with the GT3 motor to the current 718 chassis.

Thanks for your thoughts JC.

Who cares what engine they use and what the exact power it'll have. It'll be better than a GT4 and that's all that counts. There will be a lot of want for the car, including by me.

CAlexio

Well.. as price will creep towards 991.1 GT3 MSRP levels ($134k remember)... Porsche will need to offer something measurably significant both in specs and performance to get people to upgrade. Remember, normally Rs models have a different shell, so aesthetically you get a lot of bang for your buck, and that's before you even get to what's under the skin. In this case it's not like this GT4RS has a different body from GT4 to differentiate it like GT3 has for example... so how much willpeople pay for a gooseneck wing and maybe some different wheels to show their peers that they got something really special worth spending $$$ over a GT4?

I think the engine matters a lot.. it has to impress like crazy when the body changes by themselves don't...

...and again, we all cross-shop... forget corvette z06, used mclaren 600LT market is within spitting distance of $130k...

Chris3963

+1. Exactly.

usctrojanGT3

Doesn't matter to me which engine they use and what the exact power will be, all I know that it'll be faster on the track than a GT4 so that's all that I care about. My hope is that they do offer up WP package with mag wheels because I'll check those boxes. 450hp...ok cool...475hp...even better. I had a lot of fun with my 981 GT4 and am looking forward to some fun with my incoming 718 GT4 while I wait my turn to get a GT4RS. I could care less what McLaren, Corvette, or any other brand offer up even if they are faster because I'm not interested and I'm sure there are many Porsche fanboys like me out there. haha

WP & RS go together well so yes I expect WP option will be offered on the GT4RS - good money spinner.

evilfij

Any chance for a higher HP Spyder? Boxster 25th? I assume anything much more power than what’s in the current GT4/spyder will be PDK only.

DK7

for me exact power boring but i would only buy if it’s a real GT engine with emotion und character.
Engine is heart of a car.
981 and 718 GT4 very good cars but very unemotinal und slack bc engine.
No comparison to my 997RS. Engine full of live and a event

ExMB

Chris mentioned an anniversary Boxster on here a while back; 1 1/2 +/- yrs ago.

Love this goofy argument about engines. Emotion, soul, etc. Does your 997RS make better vroom vroom noises?

Like listening to Ducati nerds waxing on about how their bikes had ‘soul’...because they made boom boom noises instead of vroom vroom noises.
