Regarding the new Europe Sound Regulations
“The standards would only affect which vehicles can be sold from 2019. The new limits would be 68 decibels for cars, 70 decibels for vans and 78 decibels for lorries. The regulation will also introduce a new noise test method for vehicles.”
The power to weight would put the presumable GT4/Spyder in the M1 category with the power to weight ratio of >200kw/1000kg and less than 4 seats. Under WOT, it cannot exceed 75 currently and as of July 1, 2020 wouldn't be able to exceed 74. That's not too far off of 78 but it could affect the muffling we hear in the videos.
Yes, this clip does sound better and different from others. Even more notable considering he wasn't doing WOT toward redline. This gives me hope.

For reference, the 2016 Carrera S max is 78db
This is what I was afraid of! As I have mentioned in the past, the new regs are hard on the noise as well. All the motorcycles (except one or two models) from '17 were impacted as well. Even the NA engined cars' (whatever is left of) sound will be greatly diminished. An era of glorius engine/exhaust note may be wrapping up just about now!

If 75db limit is effective from '20, the Spyder doesn't have to comply since it's gonna be MY19, right?
What if the engine is indeed NA but complying with new noise regs? We don't know what they were testing. The proto was just cruising around in low RPMs, shifting early. What if the crew was messing with us? The off-throttle crackles do sound like 981 Spyder, not 982 GTS. However, if it's indeed a turbo (regardless 4 or 6), it would be a great let down! After numerous covert and overt indications by multiple parties, including the CEO, if they pull the rug under us, would be a massive disappointment!
Even if it's NA, the sound is not gonna be as good as 981 or GT3, thanks to regs. Not sure I would be interested. If it's turbo, all bets are off! I have started thinking about Plan B!
As for the launch, it needs to happen this year. The teams need to lay their hands on the GT4 to prep for next season.
After driving a 991.2 Targa GTS for the past 45 days, I have become in tune with the turbo whoosh. Maybe my hearing os going too, but I can't pick it up on the video. I guess time will tell...
Man. I don't despise turbo whooshes from most cars, but there's a distinctive whoosh the 3.0 Porsche flat six turbos make that's like nails on a chalkboard to me. It's not a blowoff sound at all, it's kind of like this seemingly artificially engineered (though I know it's not, it's likely just how the turbos sound) EV "wheeeee," I hate to use the "vacuum cleaner" comparison but truly it's how it sounds to me.
I just can't imagine a proper GT car exhibiting such a sound.
Sounds turbo to me. In the video with the yellow 718 following the Spyder it seemed the 718 was louder because it was on the power more than the Spyder was. Seemed like the 718 was accelerating.

Yeah, you're right. If it does end up being released in 2019 (likely), they only need to comply with the 75db limit but that is lower than current cars. The 981 GT4 was in the 90s. That's a massive jump. Fixing the muffled sound is presumably easy. See: Povic, Akra. If it's N/A, you can make it scream again provided the particulate filter and all the other stuff doesn't contribute heavily to the muffling. Even then, I'm sure there's ways around it.
As for the launch, the GT4CS will be testing publicly this summer (starting next month non-publicly) and all of the clubsport racers and members with cleaning ladies seem to think the next GT4 is N/A.
Unless I'm seeing things, the exhaust configuration on spyder is materially different than gt4. That is disappointing. Because, at a minimum, it's not remotely the same engine that is in the gt4. I just can't believe porsche would make the spyder turbo while the gt4 is NA. It doesn't make sense to me. But the different exhaust configuration (away from the gt3/gt4 centered double tips) and the neutered sound clips; the evidence points to turbo spyder and NA gt4. I would have lost a LOT of money betting against that as an outcome.
The only GT4 that has been spied (parked) has the same exhaust config. In that thread, we've been over the exhaust config countless times. It's inconclusive. The 718 has center exit even though it's turbo. Porsche can realistically put the exhaust wherever they want.
I was thinking about these mules for the 982 versus the mules we saw before the 981 debut. We are quite luck Porsche is teasing us with so many public appearances. With the 981 we only had three go public. One didn’t even have the rear hatch and roof... only indication was the front bumper and and brakes. One was hot weather testing in South Africa and the last was IIRC at a gas station and had the red Spyder interior with the seat logos with tape covering them. None of them were 100% correct... rear diffuser and wheels didn’t appear until actual debut. Makes me wonder what cosmetic items won’t appear until debut?
hmmm my 981 Spyder sounds better and or different that the videos.
What is your audio output? This was playing the video on an Apple cinema display... so maybe I'm losing audio quality. The last portion of the video where the throttle is let off and you get the burbling is what made me think it sounded like mine. I realize the existing 3.0 does it but I didn't think to the same extent? Might be my lack of experience with it though.
