(Full disclosure: Porsche wanted us to drive the 2020 911 Carrera S so badly that it flew me to Valencia, Spain, put me up in a hotel, fed me a lot of food and rented out the Circuit Ricardo Tormo for a whole day.)

Eh, 992 is different. Coasting mode never activated automatically... Bad bad news on this awesome car

I've driven 992 on street and track, car has a vastly improved PASM system compared to 991.1/2. This in-turn makes it more comfortable and yes, quieter. Whether the general road noise from larger tires/us still wanting the driver to feel the road is still too much for you, that's a personal opinion. But if greater general comfort/ the car being more quiet than its predecessor is the question, then its a yes to both parts. Would have no issue daily driving the 992 on a primarily highway commute.

It would be great if an existing owner would measure decibel levels at highway speeds in the 992. Free app decibel X and others available online in App Store.

i saw a spreadsheet that charted 67 dB in the macan and 73 dB in the 911 at highway speeds.

do you happen to remember which video? thanks

Thank you for perfectly demonstrating the buyer that Porsche is targeting and who the 992 may be the perfect vehicle for. More acoustic glass Porsche! Listen to the man!

As we've seen with the 991, the 911 platform is quite flexible. There's room for terrific grand tourers (fast, comfortable, and refined) and track destroyers (fast, raw, loud) within the same line. That's a good thing. I urge you to stop being so negative about the Carrera and instead channel your energy towards the qualities you're looking for in the next GT3.

Perhaps you're unaware of European emission laws basically mandating the particulate filter, preventing the future engines from sounding as good.... Or perhaps you're unaware of American laws requiring a backup camera meaning you're stuck with 30" iPad infotainment across all coming 992 models.

Since I don't work for Porsche - I don't think channeling either one of our "energies" is going to have much effect on the future design decisions that Porsche's B team makes.

Although now that I think about it, a 992 CUP might be a great car.

+1. Certainly you wouldn't mistake the cabin noise for an S-class, in fact I'm not even sure the word quiet applies, really, but cruising on the highway in 8th gear in normal mode for a few hundred miles wouldn't be a source of fatigue.

Does anyone know if Active Noise Cancellation is used in the 992? We know already there are microphones in the wheelhouse (for triggering wet mode). Theoretically that could be used for suppressing cabin noise, but I can't find any info about it.

JHesketh

It’s not. In fact, noise is piped into the cabin through tubes (symposers) in the firewall.

The Wet Sensors are also in the wheel arches rather than the wheelhouse (cabin).

It seems to me that Porsche is not aiming for ‘silent running’ with the 911, more ‘emotional stimulation’ and ‘flat six character’.

I feel we are unlikely to see active noise cancellation being used in a 911 except perhaps to counter the gnawing whine of an electric motor. The Taycan creates an artificial electric motor noise to try to bring character and atmosphere. That probably indicates a future direction.

erik_plus8

Yep, I know about the symposers. (I even plugged mine in my 981GTS...). Symposers are channeling the intake sound into the cabin. However, I felt, when test driving a 992 C2S a week ago that exhaust sound was more pronounced, more "clear" inside the cabin, rather than the outside (because I listened with the windows down). That didn't make sense. Since that is not from the symposers, it got me thinking they're doing something with the speakers. As BMW has done for ages, and as you point out, Porsche already do in the Taycan.... Would be really interesting to know...

Yes, I meant wheel arches and not the cabin ("wheelhouse" is cabin...? On a ship, yes...but...?)

So maybe my question isn't really if they're using ANC, rather if the engine sound is enhanced electronically, on top of the existing symposers. Remember Porsche is no stranger to this, having even put a separate speaker unit in the 4-cyl 718s to help the situation...

chuckbdc

There might be no information because its not happening.

erik_plus8

Are you 100% sure? With respect to electronic engine sound enhancement, I can imagine Porsche not being very interested in bragging about this, since it hasn't been a popular technology/system among other brands. Also, I think they didn't really lift up the 718 solution (extra speaker) either. That was revealed when someone had their car apart (As I understood it, I might be wrong)

If you want a car as quiet as the Panamera, don’t get the 911. They have two very different goals. There are a lot of quiet cars out there compared to the 911 so look at a luxury car such as Mercedes or just drive the Panamera. Road noise is very subjective and also heavily affected by tires and road conditions. I just put PS4s on my E63 and it significantly improved the handling and less road noise. For 2021, you can get the lightweight glass option on the 911 which also reduces road noise,
