Cadillac implements new material to make Lyriq 80% quieter

The Cadillac LYRIQ, which has been dubbed “crypt-quiet” and “the quietest car I can remember driving” by the press, sports an electric AC compressor mounting bracket made of Vydyne AVS, which effectively helps damp that component’s vibrations at the source while also providing structural support.

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.

Police seized the computer of an IG Metall member at Tesla Giga Berlin on Tuesday amid allegations that a works council meeting was secretly recorded. 

The union has denied the electric vehicle maker’s allegations.

In a post on X, Gigafactory Berlin plant manager André Thierig stated that an external union representative from IG Metall attended a works council meeting and allegedly recorded the session. Thierig described the event as “truly beyond words.”

“What has happened today at Giga Berlin is truly beyond words! An external union representative from IG Metall attended a works council meeting. For unknown reasons he recorded the internal meeting and was caught in action! We obviously called police and filed a criminal complaint!” Thierig wrote in his post on X.

Police later confirmed to local news outlet rbb24 that officers did seize a computer belonging to an IG Metall member at the Giga Berlin site on Tuesday afternoon. Tesla stated that employees had contacted authorities after discovering the alleged recording.

IG Metall denied Tesla’s accusations, arguing that its representative did not record the meeting. The union alleged that Tesla’s claim was simply a tactic ahead of upcoming works council elections.

The next works council election at Giga Berlin is scheduled for March 2 to 4, 2026. The facility’s management had confirmed the dates to local news outlets. The official announcement marks the start of the election process and campaign period.

Approximately 11,000 employees are eligible to participate in the vote.

The previous works council election at the plant took place in 2024, and it was triggered by a notable increase in workforce size. Under German labor law, regular works council elections must be held every four years between March 1 and May 31.

Elon Musk’s xAI plants flag in Bellevue AI hotspot

The lease places xAI’s new office in one of the region’s fastest-growing tech hubs.

Elon Musk’s artificial intelligence company xAI has leased a full floor at Lincoln Square South in downtown Bellevue, WA, as per city permit filings. 

The lease places xAI’s new office in one of the region’s fastest-growing tech hubs.

Public records indicate that xAI leased roughly 24,800 square feet in Lincoln Square South. The location was previously occupied by video game company Epic Games. Lincoln Square South is part of the Bellevue Collection, which is owned by Kemper Development Co.

The lease was first referenced in January by commercial real estate firm Broderick Group, which noted that an unnamed tenant had secured the space, as stated in a report from the Puget Sound Business Journal. Later filings identified xAI as the occupant for the space.

xAI has not publicly commented on the lease.

xAI hinted at plans to open an office in the Seattle area back in September, when the startup posted job openings with salaries ranging from $180,000 to $440,000. At the time, the company had narrowed its location search to cities on the Eastside but had not finalized a lease.

xAI’s Bellevue expansion comes as Musk continues consolidating his businesses. Last week, SpaceX acquired xAI in a deal that valued the artificial intelligence startup at $250 billion. SpaceX itself is now valued at roughly $1.25 trillion and is expected to pursue an initial public offering (IPO) later this year.

Musk already has a significant presence in the region through SpaceX, which employs about 2,000 workers locally. That initiative, however, is focused largely on Starlink satellite development.

Bellevue has increasingly become a center for artificial intelligence companies. OpenAI has expanded its local office footprint to nearly 300,000 square feet. Data infrastructure firms such as Crusoe and CoreWeave have also established offices downtown.

SpaceX blocks unauthorized Starlink terminals used by Russian troops

Ukrainian officials confirmed that Starlink terminals believed to be used by Russian troops were disabled after coordination with SpaceX.

SpaceX has taken steps to block unauthorized use of its Starlink satellite internet network, a move Ukrainian officials stated is already disrupting Russian military communications. 

Russian units lose a key communications tool

As per a report from The Guardian, Ukrainian defense officials have confirmed that Starlink terminals believed to be used by Russian troops were recently disabled after coordination with SpaceX. The move reportedly affected frontline communications and drone operations, especially in areas where traditional military radios are unreliable or easily jammed.

For months, Russian units had relied on large numbers of illicitly obtained Starlink terminals to stay connected along the front. The satellite internet service allowed faster coordination and more precise drone use for Russian forces.

Several Russian military bloggers close to frontline units have acknowledged the impact of the Starlink shutdown, with some describing sudden connectivity problems in the satellite internet service.

Russia lacks comparable replacement

Russia does not have a satellite internet system that matches Starlink’s speed, coverage, and ease of deployment. Alternatives such as fiber-optic lines, short-range wireless links, and digital radio systems take longer to install and work inadequately for fast-moving units.

Russia does operate limited satellite communications through state-linked providers, but those systems rely mainly on geostationary satellites, which are notably slower. Coverage is uneven, and data capacity is far lower than Starlink’s low-Earth-orbit network.

For now, Ukraine has stated that it has introduced a verification system that allows only approved Starlink terminals to connect. Devices believed to be linked to Russian forces are blocked from the network. That being said, Ukrainian officials have also claimed Russian units are trying to work around the restrictions by asking civilians to register Starlink terminals in their names.
