Tesla Model Y’s quiet cabin is a subtle, critical selling point for all EV buyers
When Tesla unveiled the Model 3 in the summer of 2017, the company had released its first affordable vehicle. The Model 3 had numerous selling points, though some first production vehicles were reported to exhibit a lot of road noise inside the cabin, especially at high speeds.
Model 3 owners looked for any number of ways to reduce the noise. These included aftermarket door seals, tire foam insulation, and other modifications. Later builds of the vehicle displayed an improved noise reduction system, as CEO Elon Musk had noted in October 2019 that cabin noise had been “significantly improved in current production” of the Model 3.
In a recent episode of Sandy Munro’s extensive Model Y teardown series, the automotive veteran took a look at the numerous improvements Tesla made to its electric crossover. While the Model Y is not a sedan like the Model 3, the two vehicles are effectively siblings as they share 75% of the same parts.
Tesla adopted several new strategies to keep the Model Y’s cabin quiet. According to Munro, the outer portion of the vehicle’s firewall was covered by a mat made of “lofted fiberglass.” Fiberglass is an excellent insulating material that is used within residential buildings and houses to maintain temperature. However, it is also useful for reducing sound due to its thick and dense nature.
The inside of the firewall, which faces inward toward the vehicle’s cabin is quite different. Tesla used polyurethane (PUR) and Thermoplastic Polyolefin (TPO). PUR is a material commonly used when soundproofing rooms and is usually shaped like an egg carton to deaden sound waves. TPO is traditionally utilized for roofing and uses a mixture of rubber, talc, glass, carbon fiber, and other materials to insulate heat and sound. It is also used to reduce cabin noise in cars, as its flexible nature allows it to be conformed to the twists and turns of a vehicle’s body.
Additionally, Tesla opted to use a series of pumpable and mastic sound deadener strips throughout the floorboard of the Model Y. These two materials can remove vibrations from the vehicle by stiffening the areas in the Model Y’s frame that are prone to excessive vibration. Both the pumpable and mastic sound deadeners were more frequently placed in the rear portion of the vehicle, where noise and vibrations are especially potent.

Tesla’s installation of these elements provided a much quieter ride for passengers and drivers. Long drives on highways at speeds of 55 MPH or more can prove to be some of the noisiest driving conditions, regardless of whether one is driving an EV or a petrol-powered car. This is due to wind, tire friction with the road, and outdoor weather conditions. These noises are easier to notice in an electric car, since the lack of a working internal combustion engine pretty much amplifies other noises in the cabin.
Tesla seems to have set out to make the Model Y its quietest car yet, and it seems to have succeeded. This is reflected in the feedback of some Model 3 owners, such as YouTube host Brian Jenkins, who recently posted a video documenting his favorite features of the Model Y after 1,200 miles of driving. Jenkins notes the Model Y’s quiet ride is one of his favorite features. He added that he expected more cabin noise, but the Model Y’s cabin remained quiet. Prior to getting a Model Y, Jenkins drove a Model 3 that he fitted with noise reduction seals.
Interestingly enough, Tesla has released Joe Mode last year, a feature that reduces the audible alerts in the vehicle’s rear to prevent kids from waking up during nighttime trips. Coupled with the Model Y’s already-quiet cabin, features like Joe Mode will be extra effective. It can even be an additional selling point for the vehicle. Every parent out there who has attempted long road trips with kids would attest to the importance of a quiet cabin when the kids are asleep, after all.

SpaceX just cleared a key FCC hurdle in its fight with Verizon and AT&T
The FCC accepted SpaceX’s bid for Grain’s 800 MHz spectrum, opening review for Starlink Mobile.
The Federal Communications Commission has formally opened its review of SpaceX’s plan to buy a nationwide block of 800 MHz spectrum from Grain Management, moving Starlink Mobile one step closer to operating as a full U.S. wireless carrier.
In a public notice issued Tuesday, the FCC’s Wireless Telecommunications Bureau said it accepted for filing the applications to transfer control of two Grain license companies, Prism License Co. 1 and Prism License Co. 2, to Starlink Spectrum Holdings, a wholly owned SpaceX subsidiary. The deal covers 546 paired licenses across 3,224 counties, reaching roughly 100% of the U.S. population in all 50 states, Washington, D.C., Puerto Rico and the U.S. Virgin Islands. The proceeding sits under WT Docket No. 26-313.
Acceptance is not approval. It means the applications cleared an initial review and the public comment window is now open. Comments and petitions to deny are due December 1, and oppositions are due December 8. The bureau also said the conditions attached to Grain’s July purchase of the licenses from T-Mobile, which require rapid buildout for terrestrial and direct to device service, would carry over to SpaceX if the transfer is approved.
SpaceX announced the agreement on October 8, saying the new airwaves would let Starlink Mobile’s signal reach phones inside buildings, something its 2 GHz spectrum from EchoStar cannot do as well. The portfolio includes up to 14 MHz of paired spectrum in the 817 to 824 MHz and 862 to 869 MHz bands, which most existing phones already support. Elon Musk called it “the last critical piece of the spectrum puzzle needed for SpaceX to provide complete phone coverage in America.”
According to the filing, SpaceX would hold up to 89 MHz of total spectrum in any given market after the deal closes, including up to 14 MHz below 1 GHz. That is far under the 385 MHz threshold the FCC uses to flag a transaction for closer competitive scrutiny, and well short of the roughly 300 MHz each of AT&T, Verizon and T-Mobile holds.
Tuesday’s notice does not decide how SpaceX can use the spectrum from orbit. A separate application SpaceX filed on October 27 seeking authority to provide supplemental coverage from space on the same frequencies, along with related waiver requests, is still pending before the commission.
The ground network is already taking shape. Last week, SpaceX picked Qualcomm to supply radios, baseband units and software for a nationwide 5G build, with deployment across tens of thousands of U.S. cell sites starting in 2027. The FCC also voted on October 29 to advance a proposal opening another 482 MHz to direct to device service, though AT&T, Verizon and T-Mobile hacritive pushed to strip nearly 300 MHz from it. SpaceX President Gwynne Shotwell has said service on SpaceX’s own airwaves is targeted for early 2028.
A Tesla upfitter has offered to take over Cybertruck lines from the company in a last-ditch effort to save the all-electric pickup from being completely canceled in the middle of 2027.
Unplugged Performance, the Hawthorne, California-based Tesla aftermarket specialist, has publicly offered to take over Cybertruck production from Tesla, funding the effort “through a consortium of investors.”
An open offer to Tesla: We fully support putting Cybercab first, and we’d be glad to take the Cybertruck line off your hands.
We’d fund it with a consortium of investors and run it at no cost to Tesla’s floor space, headcount, or focus. All of that goes to Cybercab. Cybercab gets first call on battery cells too. We’ll wait our turn.
Tesla gains incremental profit: a license fee, plus FSD and Robotaxi network revenues on every vehicle built.
We’d build the Cybertruck, a three-row CyberSUV, and an unmanned CyberCargo hauler. More autonomous miles, across every surface of this planet and beyond.
Worth a conversation?— UP (@UnpluggedTesla) November 10, 2026
The proposal comes as Tesla prioritizes its Cybercab Robotaxi program and prepares to wind down Cybertruck assembly at Gigafactory Texas around mid-2027.
Founded in 2013 by Ben Schaffer and located adjacent to Tesla’s Design Studio and SpaceX, Unplugged Performance has become a leading provider of premium upgrades for Tesla vehicles, including extensive Cybertruck packages under its UP INVINCIBLE line.
Through its UP.FIT division, the company has also developed purpose-built police and fleet versions of the Cybertruck, including deliveries to agencies such as the Las Vegas Metropolitan Police Department.
In an X post on Tuesday, Unplugged said:

The arrangement would free Tesla resources and manufacturing capacity for Cybercab while allowing continued production of the stainless-steel pickup and expanded variants. Unplugged Performance indicated it would wait for battery cells after Cybercab needs are met and would generate ongoing revenue for Tesla through licensing and software/network services on the vehicles it produces.
Following strong initial interest, Unplugged Performance posted a follow-up inviting potential investors and strategic partners to email cyber@unpluggedperformance.com. The company clarified that the outreach is solely to gauge interest and does not constitute an offer to sell securities or acceptance of funds at this stage.
The proposal arrives shortly after Elon Musk indicated that Cybertruck production in Texas would be phased out by roughly the middle of 2027 to expand Cybercab output.
Whether Tesla engages with the offer remains to be seen, but the public overture highlights both the aftermarket specialist’s deep experience with the Cybertruck platform and the growing focus on autonomy within Tesla’s manufacturing plans.
Elon Musk said the Tesla Cybercab will perform “a majority of all passenger miles” where it is allowed to operate and that point is “obvious to anyone with eyes and a brain.”
Musk used the point to double down on the company’s decision to ax the cult-favorite Cybertruck, as its production space will be removed and transitioned into additional Cybercab lines. The move has catalyzed a polarizing conversation on whether its right or wrong.
Whatever side you are on — it’s happening.
Dodge ended the Viper.
Audi retired the R8.
Mitsubishi said goodbye to the Lancer Evo.
Ford bid farewell to the Bronco (at one point).
Chevrolet sunset the Camaro.Tesla is ending the Cybertruck. I’m pissed. I’m upset.
Fans of those five automakers mentioned did the same thing. It happens. It sucks. I don’t like it.
But I still love Tesla. I love my Model Y. I hoped to be in a Cybertruck in a little under two years.
I won’t be. But I still won’t put my family in anything else. Too safe. Too advanced. Too much better than everything else.

Regardless, Musk seems to be getting to the point that he is done talking about the choice. At some point, you have to think that this was truly a difficult decision for him and the company as well, and this is not something he took lightly. In fact, he’s probably a little bit disappointed with it, too.
But the point remains that the Cybertruck is gone. Musk’s focus is purely on developing an autonomous platform that the world will utilize for transportation, and he’s telling you that anyone “with eyes and a brain” can see it:
@PalmerLuckey @carlhancock Cybercab will do a majority of all passenger miles in any jurisdiction where it is not prohibited by law.
Obvious to anyone with eyes and a brain.

Tesla is betting that all of its passengers in the future will be okay with not owning their own personal cars and will be fine with ride-hailing for the rest of their lives. Every dinner, every errand, every trip to the airport and transportation thereafter, will all be operated by ride-sharing, and in Tesla’s perfect world, it will happen in a Cybercab.
As of now, Cybercab is only active in Austin, but it has been spotted all over the country with a driver behind the wheel in those prototypes. In Austin, the car has no steering wheel or pedals for people to control the vehicle.
The Cybertruck dilemma is one that has truly come across the entire Tesla community and while it seems to be a great idea to keep it because people love it, the business side of things is steering Musk and Tesla in another direction.
