Tesla’s ‘Bioweapon Defense Mode’ is proving invaluable once more amid CA’s wildfires

Published

on

Tesla Model S and Model X owners affected by the ongoing wildfires in CA are thanking the electric car maker once more for their vehicles’ Bioweapon Defense Mode, which allows passengers to breathe clean air inside the cabin despite hazardous air conditions outside. 

The state of CA is currently experiencing several blazes. In Southern CA alone, authorities from the Riverside County Sheriff’s Department have confirmed that the Sandalwood Fire in Calimesa has taken the lives of two individuals, an 89-year-old woman in a mobile home and another person that is yet to be identified. 

The Sandalwood Fire, which has so far burned 820 acres and was at least 25% contained as of Saturday, is only one of several blazes in the state. The Saddleridge Fire, currently the largest in the state, has burned more than 7,500 acres and destroyed around 31 homes. Amidst these blazes, the South Coast Air Quality Management District has urged residents to protect themselves from heavy smoke and dangerous air conditions. 

It is these dangerous air conditions that are being addressed by Tesla’s Bioweapon Defense Mode for the Model S and X, and some electric car owners have taken to social media to share their experiences with the feature. A Tesla Model X owner who goes by the handle @BLKMDL3 on Twitter, for one, mentioned that Bioweapon Defense Mode was a “lifesaver” as he and his passengers were traveling in Los Angeles.

“Thank you Elon Musk and Tesla for helping us with breathing issues during the fires today in Los Angeles due to bad air quality. Bioweapon defense mode is a life saver,” the Tesla owner wrote.

Fellow Tesla enthusiast and r/TeslaMotors subreddit member u/cherrycolasoda shared a similar experience that was briefly captured on film. The Tesla enthusiast mentioned that Bioweapon Defense Mode significantly helped with the air quality in the cabin as they passed through an area that was practically surrounded by fires. The vehicle’s Autopilot system reportedly functioned normally, following lane lines without any difficulties despite the conditions on the road.

Bioweapon Defense Mode is made possible by the extremely large HEPA filter in the Model X (later equipped on the Model S as well). Tesla notes that Bioweapon Defense Mode is “100 times more effective than premium automotive filters, removing at least 99.97% of fine particulate matter and gaseous pollutants, as well as bacteria, viruses, pollen, and mold spores.”

These statements were met with a notable degree of skepticism and dismissal from critics, though Tesla later demonstrated Bioweapon Defense Mode’s capabilities by holding a test on a Model X. During the demonstration, the company placed the all-electric SUV inside a bubble contaminated with extreme levels of pollution (1,000 µg/m3 of PM2.5 vs. the EPA’s “good” air quality index limit of 12 µg/m3). Bioweapon Defense Mode effectively scrubbed the air inside the Model X’s cabin in 2 minutes, and over the next few minutes, the vehicle started cleaning the air around the SUV as well.

Elon Musk confirms Tesla AI6 chip is Project Dojo’s successor

Tesla’s AI5 and AI6 chips are expected to be rolled out to the company’s consumer products.

Earlier this week, reports emerged stating that Tesla has stepped back from its Project Dojo initiative. While the reports were initially framed as a negative development for the electric vehicle maker’s autonomous driving efforts, CEO Elon Musk later noted on X that Tesla was indeed halting its Dojo initiative.

Elon Musk’s Confirmation

As per Musk, Tesla was shuttering Project Dojo because it does not make sense for the company to divide its resources and scale two different AI chip designs. Dojo, after all, is designed to train the company’s autonomous driving program, and thus, it would not be rolled out to Tesla’s consumer products.

In a series of posts on X, Musk stated that it would make sense to just use Tesla’s AI5/AI6 to train its FSD and Autopilot systems. “In a supercomputer cluster, it would make sense to put many AI5/AI6 chips on a board, whether for inference or training, simply to reduce network cabling complexity & cost by a few orders of magnitude,” Musk said.

Tesla’s AI5 and AI6 chips are expected to be rolled out to the company’s consumer products, from Optimus to the Cybercab to the next-generation Roadster.

AI6 is Dojo’s Successor

What was particularly interesting about Musk’s comment was his mention of using AI5/AI6 chips for training. As per Musk, this strategy could be seen as “Dojo 3” in a way, since the performance of Tesla’s AI5 and AI6 chips is already notable. Musk’s comment about using AI6 chips for training caught the eye of many, including Apple and Rivian alumnus Phil Beisel, who noted that “AI6 is now Dojo.”

“Dojo is Tesla’s AI training supercomputer, built around a custom chip known as the D1. The D1 and AI5/AI6 share many core design elements, particularly the math operations used in neural networks (e.g., matrix multiplication) and highly parallel processing.

“Dojo had a unique feature: chips arranged in a 5×5 grid using a system-on-wafer design, with etched interconnects enabling high-speed data transfer. In a sense, Dojo will live on as the generalized AI6. Going forward, all efforts will focus on AI6,” the tech veteran wrote in a post on X.

Elon Musk confirmed the Apple alumnus’ musings, with the CEO responding with a “bullseye” emoji. Musk is evidently excited for Tesla’s AI6 chip, which is expected to produced by Samsung’s upcoming Texas fabrication facility. In a post on X, Musk stated that he would personally be walking Samsung’s line to accelerate the output of Tesla’s AI6 computers.

It took a while, but the Tesla Cybertruck’s rock sliders and battery armor upgrades have finally arrived. The upgrade was announced by the electric vehicle maker on social media platform X, to much appreciation from Cybertruck owners.

Tesla Releases Cybertruck Armor Package

As could be seen in Tesla’s official Shop, the Cybertruck Terrestrial Armor Package is available only for Foundation Series units for now, though non-Foundation Series vehicles should have access to the upgrade around September 2025. Price-wise, the armor package is quite reasonable at $3,500.

For that price, Cybertruck owners would be able to acquire enhanced rock sliders and an underbody battery shield that should allow the all-electric pickup truck to go through harsh terrain without any issues. Each purchase of the Terrestrial Armor Package includes 1 Underbody shield, 1 Left side structural rocker, and 1 Right side structural rocker.

Most importantly, the Armor Package’s price includes shipment to the customer’s preferred Tesla Service Center and installation.

Extra-Terrestrial

Tesla describes its Cybertruck Armor Package as follows: “Get extra-terrestrial. The Cybertruck Terrestrial Armor Package includes enhanced rock sliders and an underbody battery shield to provide greater protection from rocks and debris when off-roading on tough terrain. The rock sliders are constructed from coated steel and the underbody battery shield is constructed from aluminum for greater protection against scraping.”

Initial impressions from a Cybertruck owner who was fortunate enough to test the Armor Package in real-world off-road conditions have been positive. The item’s pricing also seems to be quite appreciated by Cybertruck owners in forums such as the Cybertruck Owners Club, with some members stating that they would be acquiring the package for their own all-electric pickup trucks.

Reports from industry watchers in China have suggested that the Tesla Model Y L has started mass production at Gigafactory Shanghai. The vehicle is expected to be a larger version of the best-selling Model Y crossover, offering three rows and six seats thanks to a longer wheelbase.

Tesla Model Y L Production Rumors

Reports about the new Model Y variant’s alleged milestone were initially shared on Weibo, with some industry watchers stating that the vehicle has already started mass production. Tesla China is reportedly surveying which of its domestic stores would have the first display units of the six-seat Model Y. 

The Model Y L’s steady march towards production was evident this past week, with recent reports indicating that the vehicle’s key specs have already been listed in the China Ministry of Industry and Information Technology’s (MIIT) latest batch of new energy vehicle models that are eligible for vehicle purchase tax exemptions.

As per the MIIT’s list, the Model Y L will be a dual motor vehicle that is equipped with an 82.0-kWh lithium-ion battery from LG Energy Solution. The vehicle will feature six seats with two captain seats on the second row, as well as a CLTC range of 751 km. 

Tesla Model Y L Potential

The potential of the Model Y L is vast, considering that it is produced in the existing Model Y lines of Tesla’s factories. This should slash new vehicle tooling costs and potential ramp-up issues. Three-row SUVs also command a pretty notable market that has mostly only been accessed by the more expensive Model X. With the Model Y L’s lower price, Tesla could become more competitive in the three-row SUV segment.

As noted by longtime Tesla owner and investor @_SFTahoe, the Model Y L could also become a more premium option for the company’s Robotaxi business, thanks to its second row captain seats and spacious interior. The expansion of Model Y L Robotaxis should also be impressive considering Tesla’s mastery of mass manufacturing techniques.
