Make no mistake about it, the climate control system for the Model X is superior to anything available from any other manufacturer and will do an excellent job of protecting its occupants from harmful elements in the atmosphere. Tesla describes the system this way, “The biodefense button is designed to allow clean medical-grade air into the cabin and keep contaminated air out. When deployed, it pushes the system into full fresh mode, pulling all HVAC air through the HEPA filter. The fan goes to max speed 11, pulling in enough air to slightly pressurize the cabin, keeping other air from entering Model X.”

But a few people with actual bioweapons experience quibble with the Tesla Bioweapons Defense Mode claims. The issue is not whether the system works, but whether its claims regarding viruses are accurate.

Colonel Randall Larsen, retired from the U.S. Air Force and now the director of the Institute for Homeland Security, tells Gizmodo that he is actually a Tesla fan. “I’m actually building a new house, and I had them put an electrical charger in the garage, just in case I buy a Tesla,” he says. But when told about the Tesla Model X “bioweapon defense mode” he laughed out loud and asked, “So, is Musk actually advertising this?”

To be considered a real HEPA filter, an air filter has to remove 99.97% of 0.3 micrometer particles from the air. That’s fine enough to catch bacteria like anthrax. It will also stop the plague and most other bacteria, as well as most pollen, dust, and fungal spores. “Now, if you’re worried about bacterial agents like anthrax or plague, a good filtering system would probably protect you,” says Larsen.

But viruses are much smaller than bacteria, which means they’re harder to filter out of the air. “Well, 0.3 micrometer won’t hold back viruses. It will hold back most bacteria, but it won’t hold back viruses. So, if you believe that all bio-terrorist agents are bacteria, then you’ll get an increment of protection,” said Michael J. Buchmeier, deputy director of the Pacific Southwest Regional Center for Biodefense and Emerging Diseases at the University of California, Irvine.

The influenza A virus is only 120 nanometers wide, so it can pass through even a 0.2 micrometer HEPA filter without a problem. “It’s a statistical game that we play,” said Buchmeier. “Any filter like that is going to be efficient to a degree but it’s not necessarily 100% efficient.”

Larsen and Buchmeier also point out that, by the time the passengers realize there has been a bioweapons attack, it will probably be too late to take protective action. “The key problem with the bio is knowing when it’s been released,” Buchmeier says. “You know, it’s not like there’s a big bang or something. It’s a pretty extravagant long shot anyway, you know, the idea that you’re going to be forewarned enough to implement this filter in time to prevent any exposure.”

None of which should take away from how good the Model X climate control system is at protecting its passengers. It can filter out allergens like ragweed and cedar pollen, fungal spores like the ones that cause Valley Fever, and irritants like smoke and dust. It could also filter out unpleasant roadside odor. “There are a lot of reasons why you would put a filter like that in, and only one of them is bioterrorism,” says Buchmeier.

Tesla CEO Elon Musk hits back at drug use claims, calls publications ‘hypocrites’

Elon Musk showed a clean drug test, dispelling any rumors of drug use that came from unfounded reports from two large media outlets.

Tesla CEO Elon Musk has responded to a report from the Wall Street Journal and the New York Times, as both publications claimed he was abusing drugs while being involved with President Trump on both the campaign trail and while he was active within the administration after the election.

A bombshell report from the New York Times, published in late May, stated that Musk was regularly using things like ketamine, ecstasy, and psychedelic mushrooms, and also stimulants like Adderall, during his time within the Trump administration.

The reports cited inside sources who claimed the Tesla and SpaceX frontman was using substances during his time with the government.

However, Musk published the results of a recent drug test performed at Fastest Labs of South Austin. They showed ‘Negative’ results across the board:

Musk was not done there.

He went on to say the New York Times “lies as easy as breathing. It’s normal for them.” He also said both the Times and Wall Street Journal reporters should also publish their own drug test results, stating, “They won’t, because those hypocrites are guilty as sin.”

Musk said years ago that he received ketamine prescriptions from doctors to treat depression. He said he had it “years ago and said so on X, so this is not even news.” He also said that ketamine “helps for getting out of dark mental holes, but haven’t taken it since then.”

Tesla fans and Musk enthusiasts have joked for days now that, if Musk were to be on drugs, other CEOs should also do them, considering his persistence on work-related projects, long hours, and commitment to his job.

Musk has now proven that there has been no drug use with this test, and it seems as if the reports could have some sort of legal impact, although he has not said he will take any action.

Tesla’s Grok integration will be more realistic with this cool feature

Tesla is preparing Grok for its first integration into vehicles, but it’s making it more robust than ever, firmware shows.

Tesla has not yet integrated the AI assistant Grok into its vehicles, but when it does, it will be even more realistic with a new feature that firmware coding shows.

CEO Elon Musk teased a few months back that Grok would be making its way into vehicles in the near future. The implementation has not yet occurred, but we are confident it will be rolling out soon, especially as Tesla has its sights set on a near-term rollout of the Robotaxi platform.

Tesla’s vehicles expected to get Grok voice assistant—but when?

Grok will enable AI assistance for drivers who are both manually operating Tesla vehicles or using the company’s Full Self-Driving suite. It has been widely popular and extremely useful for users on X, Musk’s social media platform.

However, Tesla hacker green has revealed through firmware that the company is planning to roll out Grok into vehicles with personalities, giving it an even more realistic tone that is totally customizable and catered to whatever the driver wants.

There are also a handful of kids’ versions that will do things like tell stories or play trivia:

The true capabilities of Grok are nearly limitless. Back in January, Musk said on a livestream on X that, “You’ll be able to talk to your Tesla and ask for anything.”

Grok appears to only be available on AMD-based vehicles, according to other things green found in the firmware. This means that Intel-based Teslas, which are usually older models, will not enable Grok support for right now.

Tesla dominates Cars.com’s Made in America Index with clean sweep

Tesla continues to dominate Cars.com’s Made in America Index with a clean sweep of the Top 4 spots.

Tesla has dominated the Cars.com Made-in-America Index with a clean sweep of the top four spots. All four Tesla vehicles that were eligible for the analysis placed in the top four.

The Model 3 overtook the Model Y for first place this year. The all-electric crossover was first in 2024, but the Model 3 managed to overtake its sibling vehicle to claim the top spot in 2025. The Model Y took second, while the Model S took third, and the Model X took fourth.

This is an improvement from last year, as the Model Y took first, but the Model S and Model X placed fourth and ninth, respectively. The Model 3 was not in the Top 10 in 2024.

“Tesla continues to lead, claiming the top four spots and showcasing its commitment to domestic production. About 25% of the more than 400 vehicles on sale in the U.S. made this year’s AMI, and whether a vehicle is No. 1 or No.99, it contributes to the U.S. economy,” Patrick Masterson, lead researcher for the program, said.

More than 400 vehicles were analyzed for this year’s study, with Cars.com officially ranking 117 of them. There were two other EVs in the Top 10, as the Kia EV6 took sixth place, and the Volkswagen ID.4 finished in tenth.

This year’s study reflected major geographic and strategic shifts across the automotive industry. Of the 117 vehicles ranked in the program, they were produced at 36 domestic factories, leaving only 11 total factories that did not yield a car on the list. There are 47 assembly plants in operation in the U.S.

However, there still has not been a vehicle to quite reach the 100 percent domestic parts content, something that is extremely elusive. Masterson says the global supply chain is still extremely crucial to even the most American-built cars on the market.

The average domestic parts content of the Top 10 cars was 83.4 percent in 2006, but that number has shrunk to 70.3 percent in this year’s rankings.

Some might wonder where cars like the Tesla Cybertruck or Rivian R1T are on the list. However, these vehicles did not qualify because the study only considers cars under a gross weight of 8,500 pounds.
