Too many trolls on here.

 

I think it's prudent to point out that the image is not a "photo". It's an AI-generated image. Someone probably typed "2025 lexus is concept", or something like that, into an AI image generation tool prompt, and the tool spat out this image.

We all know the 2025 is continuing on as the current generation model with few, if any, changes.

 

100%.

This.

 

Lexus is like Rolex.
Very conservative.

Rolex pulled stellar dial OP41 (Turquoise, Coral & Yellow) out of mart in 2022 & permanently discontinued the 2021 release for these 3 colors for larger dials, due to speculated enamel none-uniformity/crack issue, between dial edge & ctr.
Rolex make tiny cosmetic change to their watch head (lug, bezel, diameter, form/shape every 10-16 years.
They add/discontinue new dials or add/discon't metals / link / clasp / end links every 13-20 years.
Rolex have their own foundry and cast their own parts for every piece of gold/platinum/steel they put on their watches.

Lexus will use Toyota parts but unlike Toyota, Lexus never use Subaru & BMW parts.
No one in Lexus will pull off fake exhaust-electrical-speaker, fake-exhaust pipe which are not connected to the engine & use Citroen engine.

Sadly that means CD-Player & 2011 mid-console & dashboard, a track-pad which you accidentally touch when you rest your arm, heater/ventilation buttons which are blocked by gear-**** & and no Apple Play Wireless/HUD.
That may also mean we will never ever see 100% EV line, 100% PHEV line, Autonomous Driving from Lexus for another 15-30 years.
Thank heavens for that, & not that I care.
No men in my family incl me will live pass 55yo.
So I have a few more years.
Lexus LC/LFA/GT3 with just wheels, pedals & **** works fine for me.
Just pray APR dun do a 1960-90s & go 12.5%

 

My IS 500 and all 2021+ IS 350 models have fake engine sound called ASC. It can be turned off, at least... but Lexus is not above using it.

 

I think you got your IS500 and all of Lexus's ASC mixed-up with BMW fake speaker generated sound which is not actually generated by any engine/tail-pipe/air-intake.
Lexus cabin door/floor/roof paddings, insulate your IS500 like all IS & all Lexus models to meet the luxury definition (quiet cabin when needed).
This also explain why the windows & windscreen on all Lexus are triple-coated.

To compensate for the superior cabin noise insulation, your IS500 use a real mechanical diaphragm from your air-intake, to balance everything out, to generate as real possible engine / exhaust sound.

That's why you dun want to replace the OEM air-intake with anything else.
Not unless you want to lose all the cold start & acceleration roars.

 

No, I did not mix anything up. In fact, my IS 500 does not even have that sound tube.

There are two different systems on the IS 350 - the sound tube, or Intake Sound Generator, as well as ASC, or Active Sound Control. In 2021 and up models, both of these things exist in tandem. There is a little dial to the left of the steering column (near the auto high beam switch) that allows you to turn the volume of ASC up, down, or off.

On the IS 500, the system is actually totally different from the Intake Sound Generator on the IS 350. There is a flap on the air box that opens up at about 2,800 RPM to allow more air into the intake while also producing more sound.

Here is the intake. There's no sound tube! This is what it looks like when the flap is open.






Here, notice I can easily close the flap with my hand when the engine is not running. Vacuum pressure is used to do this while the engine is running.



And here is the "ASC" dial. The sound comes through a speaker on the dashboard. In fact, you can see the speaker grille to the right of the steering column, but I didn't bother taking a photo of that.

 

All ASC output comes from speaker.
The engineers in Lexus ensured us it's as real regardless of where the diaphragm (input) is located, be it thru a air intake tube (350) or box (500).
It's all mechanical input, based in air intake which is directly correlated to engine & exhaust roar, which differentiate it from CPU generated input by BMW.

You can also remove all floor, door & roof sound insulation pads/foam, & replace all the OEM UV-A, B & C triple coated windows & front+rear windscreen with Pilkington UV-A sheet-glass used by Toyota/Subaru/BMW for real engine /exhaust, as loud as Maserati

 

All right, this topic has already been discussed before... there is no new information here.

ASC is digitally-created sound played through a speaker. All other forms of sound enhancement, like the induction sound from the airbox or the Intake Sound Generator, are "real" and not digitally augmented.

Let's get back on topic, please.

 

>ASC is digitally-created sound played through a speaker.

Stick'n w the thread swipe for one more minute ...
I bought my CPO IS 350 this spring and have never been able to make the ASC work. I've turned the volume roller up and down, but can hear no difference.
I usually have the radio playing, wonder if that is overwhelming the engine sound ...
Which speaker does the engine noise come out?
Thanks
===================================
Angle parked in a parallel universe

 

It's well-hidden. It's to the right of the steering column. All you can see is just a couple small slots in the dashboard (not a full speaker grille).

I found the ASC very noticeable. Maybe yours has been disconnected somehow? Previous owner was not a fan?

 

Me2, actually I barely noticed it in Eco/Normal or in any Auto driving mode.
Had to use Sports & Manual, floor the pedal to even notice it.
Quite useful when I am grabbing my coffee 6-7am when there's no traffic & I can go ballistic >3500rpm.
Other than that, if I am driving to work in auto transmission, there's no difference from any speaker, when ASC is maxed, regardless of rpm, gear & speed I'm at.

Changing topic.
I test drive a Porsche Taycan which has a loud-specker, not just inside the car, but outside the car to project fake ICE / exhaust sound, on a full EV.
1st & last time I laughed so hard during test-drive.
It was a Taycan Turbo 4S with 911 price tag.
No thanks; Can't afford the APR, lease, nor insurance.
And can't imagine myself zooming pass people in Santana Row with external-speaker generated engine/exhaust sound, from a full EV.
I pray Lexus dun do this to us, it will be the death of the brand.
In short, when I see Porsche these days, I imagine it as how I see my own Lexus, just a better built Toyota. Yes, Porsche is just re-badged VW.

 

But they have done all of those besides use a non Toyota sources engine. The ISF had fake exhaust tips, The current IS350FS has fake engine sounds playing though the speakers...

 

No one force you to buy cars with fake exhaust tips & no one force you to turn the ASC volume up/on (you can set it to zero).
There're 70 different car makes in the world.
Perhaps try Maserati.
Best sounding car ever, especially the Quattro

 

Yeah, the fake tips are something I would have to correct if I owned an ISF. BUT controversial opinion, I actually don't think the 'enhanced' sounds are the worst thing in the world and I think they did a decent job with it on the current 350. I kind of like the idea of the car sounding 'enhanced' from the inside, while not having some loud exhaust that tells every cop in the 2Mil radius someone just floored it from the outside. So maybe that is fitting with the whole conservative Lexus thing?
And yes; my friend had a MC Stradale he managed to put 130K miles on over 8 years. That V8 made music .
