I will assume most don't know what this is; I did not until I noticed it on my Order Detail sheet and looked it up. It stands for Next Generation Power Train Sound Quality. Lacking any luck in my research, I presume this is an evolution of the Symposer technology, wherein exhaust and engine notes are somehow routed through the car's speakers. The literature I've found indicates that this takes place whether or not the audio system is turned on. The feature is supposedly adjustable although I have had zero success in determining how that is accomplished.
So, if anyone knows how to adjust this, please respond as I would like to fiddle with it to see what effect it has. So far as I can tell to date there is no engine or exhaust notes being broadcast through the speakers. Any other information on this would also be appreciated.

 

I thought that the Symposer feeds engine noise into the cab through a physical diaphragm, without involving the sound system, but I may be wrong.

 

You're correct about the Symposer. Google found the following on a LR dealer's website...

Next Generation Power Train Sound Quality | Land Rover Edison

 

Just horrible.

 

So - it's a prerecorded track - not even your actual engine noise?

So could you put the V8 soundtrack on the 4-pot car??

 

The Symposer is purely mechanical and pumps intake manifolds noise through a speaker/diaphragm into the cabin:

 

Maybe we need to confirm the model year in question. Pretty sure that my MY15 car is purely mechanical.

 

But the above says that the system 'constructs' an electronic sound based on speed and revs sent through the audio speakers. So that's not the Symposer. It sounds artificial and electronic synthesized

 

The OP (SassySarah) has a new MY2022, and I am fairly sure this is the first year of the NGPTSQ system.
Others have commented before that the Symposer was dropped a year or two ago but I don't know if there is a gap between dropping the Symposer and equipping the car with NGPTSQ.

 

I was just showing what the Symposer is so as to point out that it is nothing like the NGPTSQ system.
I am 99% sure that the NGPTSQ has replaced the Symposer so no F-Type (or any other JLR product) would have both systems.

 

The symposer system is an abomination, but an easily disabled one. The NGPTSQ system sounds like a different abomination. Other manufacturers have been doing it for years, but if it can't be disabled I'm doubly glad I bought when I did.

 

When we all drive EVs, all we will have is precorded exhausts and deer /pedestrian warning sound generators!!
Welcome to the synthetic world of the future.

 

Just wondering, what noise does a deer make when it is about to run across the road in front of you???
And the same for an addled/drunk pedestrian???

 

My 2021 F Type with a build date of March 2021 does not have the Symposer. I had read about it and was ready to disable it but when I started to look around under the hood I discovered that my car did not have all the extra plumbing for the Symposer system.

To me, it sounds like the exhaust sound from about 3500 RPM and up, or when crackling and popping when downshifting or letting off the throttle when holding it in one gear is coming from right below the seats/floorboard and whatever exhaust system component is located right there.

The only thing I found on my build sheet with respect to the exhaust system was this: 076JB Exhaust Resonator - Standard

Maybe the NGPTSQ is something new for the 2022 models ?

 

I am reviving this thread to find out if anyone with a 2022 model year F-Type has learned anything whatsoever about this feature--specifically how to adjust the volume. I've tried everything I know to try and can't detect any artificial auditory enhancements much less any adjustability.

 

What's so bad about it? Honestly don't understand the hate? Is it just that it pumps engine noise into the cabin? Or the unneeded complexity?

 

It's primarily two things:

1) Under some conditions it's really obvious that it's activating. The sudden change in sound is different than when the active exhaust switches and more intrusive.
2) The quality of the sound. It's a disembodied drone that resonates in the cabin that sounds like neither intake nor exhaust. It just sounds *wrong*.

Secondarily, I find it unnecessary and extra parts that add no value do not belong.

When I disabled it I immediately was happier. Engine sounds come from the front and exhaust sounds from the rear, as nature intended. I'll note that some did not notice any difference after disabling it per my write-up. Perhaps there is a difference between years, maybe it's a 6MT thing, or maybe either theirs or mine was defective. In any case, I'd planned to install a valve to be able to switch it and even went so far as to get the parts, but the more I drove the more I resolved that I'd never want it again.

 

Well, thanks gentlemen, your comments have absolutely nothing to do with my revival of this thread. The system of which I speak is the next generation of the Symposer system, and as I've stated I can tell no difference in volume, tone, pitch...anything that I might interpret as a synthetic software attempt to enhance power or engine noises.
Never mind, I'm leaving.

 

Take care!

 

I was answering a question from a comment of June of last year about the old system. If the system that replaces the symposer does not have that same artificiality then perhaps you're trying to solve a problem that doesn't exist. It's also possible that there is no such adjustment and therefore no answer to your question. I don't know.
