That's a massive drop indeed! Spyder isn't a Spyder without a good sound! Hope you are right about ways to make it sing again, if NA. I still think it is NA. There is some funny business going on with that proto. Chances are, as soon as it debuts, we will have to start looking into clearing it's musical channels. I am sure technically-minded members will dig into this whole particle filter thing. But, it is emission related; so, we can't mess with it much. In any event, regardless of the engine, the sound is gonna suck, out of the box! It is gonna need work to be on par with 981 Spyder.

If GT4CS is going to be let loose in a month, at least privately, we don't have to wait long for answers.

The thing about noise limits is that I don't believe they apply to whatever happens when you turn PSE on. It will be measured with everything in its default condition. They may need to stop opening the valves automatically at high RPM and loads but other than that I don't think they'll suddenly need to become very quiet.

spyderphile

If that's the case, then we are in luck! If PSE opens everything up, regardless of the regs, we wouldn't have to worry about it. Thanks for clarifying; great relief!

Similar to the turbo fours compared to the NA flat sixes. Done to meet a regulation that doesn't mean much in the real world.

You're right. They will use the stock exhaust as well. However, they do have to have a period of WOT where the "throttle is depressed as rapidly and safely as possible to the floor". If the flaps open on load in addition to RPM, then they would need to kill that as well. All that said, flaps closing isn't going to muffle 20db of sound. The cruising speed tests are done at 1/2 RPM essentially so that automatically is quieter. Really, though, who knows. This might be the sound of the 4.0 at low to mid revs after it's been restricted in some fashion and the noise regulations. Or it could be turbo. It's nothing like the F4T in the 718 so we at least have that going for us.

Obviously, Porsche also gets away with the GT3 sound being what it is, though I'm pretty sure that one only has to comply with 80db because they can wave it away with "this version of this car has 4 seats therefore, it is a different class".

spyderphile

Actually, GT3 doesn't have 4 seats! And, shouldn't a 4-seater have even lower limit since it tends to be just sporty (or, a regular family type) as opposed to a sports car?

blackholescion

What I was getting at is they might be able to say, for the GT3, car x has 4 seats and this is based on it so therefore, we are in a different class. As for the 4 seats thing, after seeing what AMG do, I'm not convinced they could get away with calling it "a family saloon". haha.

Haha this would be fantastic then maybe I could pass sound at laguna with a stock car.

This car is 3.0T for sure. I'm actually wondering if that diffuser is a clever way to mount an inter cooler? Wouldn't a big cutout like that allow air to move from some front intakes perhaps underneath through the middle with the happy side effect of providing extra downforce. dunno.

That's a 4-Cyl sound

What a pity.

I like how people hate on the H4 engine for its sound, but in reality don't even know what it sounds like lol

digitalrurouni

Disagree. People are having a hard time accepting and understanding the sound that remotely does not sound like the sound that should be generated by the motor Porsche said the car would be powered with. So that sort of a "am I hearing that right" doubt pops in to mind. Every magazine is harping on about the gt3 4 liter flat 6 when it sounds like a turbo setup.

I fall in to the camp where there's no doubt it's a turbo motor albeit the 6 cylinder.

Sounds more like the 6 turbo in my Cayenne GTS...
