Cadillac implements new material to make Lyriq 80% quieter
A new material used in the Cadillac Lyriq and made by Ascend Performance Materials is designed to make electric vehicles 80% quieter.
Noise Vibration and Harshness (NVH) material has long been used in the automotive industry to limit the factors that make up its name; noise, vibration, and harshness. Automakers can make their vehicles significantly quieter and more comfortable by targeting certain vibration frequencies. And with a new material designed specifically for electric cars, the Cadillac Lyriq can become up to 80% quieter.
The unique material called Vydyne AVS is made by Ascend Performance Materials in Houston and is already being used in the Cadillac Lyriq. According to the company’s press release, by targeting specific frequencies given off by EV motors and compressors, Vydyne AVS can reduce cabin sound pressure by 80%.
As a result of this material, drivers limit motor and road noise while not sacrificing safety; drivers can still hear the vehicles and emergency vehicles around them. As the company notes in its release, this creates a “crypt-like” quietness in the cabin while driving, and this has come out in multiple reviews of the now hotly demanded Cadillac Lyriq.
The other material the company has announced today is a fire safety material designed to keep passengers safe in the case of a battery fire. While battery fires are uncommon in electric vehicles, being prepared for the worst-case scenario can be the difference between life and death. Starflom X-Protect is a nylon-based flame retardant that can prevent battery fires from ever affecting the internal occupants of vehicles.
In a video posted by the company, Starflam X-Protect is shown to be able to withstand 1,000 decrease celsius for 15 minutes before the test is halted. In contrast, other flame retardants and simple aluminum plating melted far before.
These great new materials can make EVs exponentially safer and quieter. Considering how much safer and quieter EVs are compared to gas vehicles, drivers will get an exponentially better experience in the coming years. And as electric motor and battery technology improves, these materials will eventually help drivers and passengers feel just as safe and calm as they are in their homes.

Tesla has adjusted the functionality of a crucial climate feature as Winter weather has started to arrive throughout some parts of the United States. The new feature was highly requested by owners.
Tesla has a Cabin Overheat Protection feature that helps keep the temperature regulated if it reaches a certain threshold. Inversely, it can be used in cold weather as well, which will automatically warm the cabin if it sinks to a temperature that is too low for the owner’s comfort.
This is a great way to keep the cabin either warmed up just enough or cooled down just enough so that it never gets too hot or too cold. Extreme temperatures could damage certain parts of the vehicle or damage personal belongings that are kept inside the car.
Overheat protection is a great thing to have in hot climates like Arizona or Texas, especially with the Premium trims of the Model 3 and Model Y, which feature a glass roof.
Many owners appreciate the feature, but they argue that using it at home will utilize too much energy, especially during extreme temperatures. For a while, many Tesla fans have requested an option to disable this feature when the car is parked at home, which the company recently added, according to Not a Tesla App.
The feature is part of Software Version 2025.44.3, and the release notes state:
“You can now choose Exclude Home when Cabin Overheat Protection or No A/C is enabled.”
Tesla has been great at listening to what owners want with new features, and this is one that will reserve some charge and prevent unnecessary utilization of available power, especially as the car is parked at home. If owners want to condition the cabin or get the car ready for operation with a comfortable interior, they can utilize the Tesla app to adjust the climate.
Tesla CEO Elon Musk revealed today on the social media platform X that legacy automakers, such as Ford, General Motors, and Stellantis, do not want to license the company’s Full Self-Driving suite, at least not without a long list of their own terms.
“I’ve tried to warn them and even offered to license Tesla FSD, but they don’t want it! Crazy,” Musk said on X. “When legacy auto does occasionally reach out, they tepidly discuss implementing FSD for a tiny program in 5 years with unworkable requirements for Tesla, so pointless.”

Musk made the remark in response to a note we wrote about earlier today from Melius Research, in which analyst Rob Wertheimer said, “Our point is not that Tesla is at risk, it’s that everybody else is,” in terms of autonomy and self-driving development.
Wertheimer believes there are hundreds of billions of dollars in value headed toward Tesla’s way because of its prowess with FSD.
A few years ago, Musk first remarked that Tesla was in early talks with one legacy automaker regarding licensing Full Self-Driving for its vehicles. Tesla never confirmed which company it was, but given Musk’s ongoing talks with Ford CEO Jim Farley at the time, it seemed the Detroit-based automaker was the likely suspect.

Ford has been perhaps the most aggressive legacy automaker in terms of its EV efforts, but it recently scaled back its electric offensive due to profitability issues and weak demand. It simply was not making enough vehicles, nor selling the volume needed to turn a profit.
Musk truly believes that many of the companies that turn their backs on FSD now will suffer in the future, especially considering the increased chance it could be a parallel to what has happened with EV efforts for many of these companies.
Unfortunately, they got started too late and are now playing catch-up with Tesla, XPeng, BYD, and the other dominating forces in EVs across the globe.
Tesla is backtracking on a strange adjustment it made to its in-car Navigation feature after numerous complaints from owners convinced the company to make a change.
Tesla’s in-car Navigation is catered to its vehicles, as it routes Supercharging stops and preps your vehicle for charging with preconditioning. It is also very intuitive, and features other things like weather radar and a detailed map outlining points of interest.
However, a recent change to the Navigation by Tesla did not go unnoticed, and owners were really upset about it.
For trips that required multiple Supercharger stops, Tesla decided to implement a naming change, which did not show the city or state of each charging stop. Instead, it just showed the business where the Supercharger was located, giving many owners an unwelcome surprise.
However, Tesla’s Director of Supercharging, Max de Zegher, admitted the update was a “big mistake on our end,” and made a change that rolled out within 24 hours:
The naming change should have happened at once, instead of in 2 sequential steps. That was a big miss on our end. We do listen to the community and we do course-correct fast. The accelerated fix rolled out last night. The Tesla App is updated and most in-car touchscreens should…

The lack of a name for the city where a Supercharging stop would be made caused some confusion for owners in the short term. Some drivers argued that it was more difficult to make stops at some familiar locations that were special to them. Others were not too keen on not knowing where they were going to be along their trip.
Tesla was quick to scramble to resolve this issue, and it did a great job of rolling it out in an expedited manner, as de Zegher said that most in-car touch screens would notice the fix within one day of the change being rolled out.
Additionally, there will be even more improvements in December, as Tesla plans to show the common name/amenity below the site name as well, which will give people a better idea of what to expect when they arrive at a Supercharger.
