Tesla’s US-made Model Y gets Bioweapon Defense Mode with hospital-grade HEPA filter

Earlier this year, Tesla started rolling out the Made-in-China Model Y to local customers. Unlike the US-made version of the all-electric crossover, the Model Y produced in Gigafactory Shanghai was equipped with a large HEPA filter and a dedicated Bioweapon Defense Mode. Recent images shared of a Model Y produced at the Fremont Factory suggest that the highly-regarded feature is now rolling out to Tesla’s US-made crossovers as well. 

Electric vehicle group The Kilowatts shared the initial photo of a US-made Model Y with Bioweapon Defense Mode on Twitter. The Model Y in question, a Long Range Dual Motor variant, was built at the Fremont Factory in July 2021. With this in mind, it appears that California-made Model Ys delivered this quarter would likely include a dedicated Bioweapon Defense Mode function. 

The addition of Bioweapon Defense Mode for the Made-in-China Model Y was quite surprising, since Elon Musk noted in the past that the large HEPA filter required for the feature would be too large to fit in the Model 3 without sacrificing the all-electric sedan’s frunk. Considering that the Model 3 and Model Y are built on the same platform, it was widely expected that the all-electric crossover would also not have enough space for a hospital-grade HEPA filter. 

Late last year, however, signs emerged suggesting that the Model Y would eventually be equipped with Bioweapon Defense Mode, just like its larger, more expensive siblings, the Model X and Model S. These include references to a HEPA filter for the Model Y in Tesla’s software, as well as an update to the Model Y’s manual which included sections for Bioweapon Defense Mode. These observations were confirmed when Tesla China formally launched the Model Y with a dedicated Bioweapon Defense Mode feature.

A look at the Made-in-China Model Y’s HEPA filter shows that the massive component was installed just behind the all-electric crossover’s frunk. This would make it easier to replace the filter when needed, unlike the Model X, which requires some disassembly when its HEPA filter needs replacing. While an image of the HEPA filter in the recently-built Tesla Model Y from the Fremont Factory has not been shared as of writing, there is a good chance that the US-made crossovers are following the same setup as their Giga Shanghai-made counterparts.

Bioweapon Defense Mode is arguably one of Tesla’s most unique safety-focused features, with a test involving a Model X revealing that the function could thoroughly clean the air inside (and even outside) the vehicle. The feature has proven itself over the years, particularly as California-based Tesla Model S and Model X owners experienced declining air quality from wildfires. The addition of Bioweapon Defense Mode for the Tesla Model Y could then make the all-electric crossover even more of a bang-for-the-buck vehicle, as it’s priced closer to the entry-level Model 3, but its cabin air filtration system is similar to the more premium Model S and Model X.

Tesla owner attempts resale of Model S Signature Edition for over $260k

A Tesla owner who purchased a Model S Signature Edition, one of the final 250 units of the all-electric flagship vehicle that the company discontinued earlier this year, is attempting to sell the car despite a no-resale clause that prohibits reselling for the first year.

The car is being sold by J&S Autohaus in Ewing, New Jersey, and is priced at $260,490, well above the $159,420 that Tesla sold it for earlier this year.

To those who do not know, the Model S Signature was a highly exclusive, limited-run farewell variant of the Model S Plaid that was produced this year to mark the end of production of both the Model S and Model X, Tesla’s two flagship vehicles.

Limited to just 250 units with invite-only sales, it serves as a collector’s item celebrating the legacy of the Model S, which helped pioneer Tesla’s electric vehicle success since its 2012 launch.

It bundles top-tier performance with bespoke cosmetic and luxury upgrades, plus Tesla’s Luxe Package. Here’s what the Model S Signature has over the typical Model S Plaid:

  • Exclusive Exterior – Unique Garnet Red Paint, matching door handles, gold Tesla “T” badges upfront, gold Plaid and Signature badging at the rear.
  • Premium Interior – White Alcantara upholstery with gold piping/accents, gold Plaid seat badges, Signature-marked door sills, individually numbered dashboard plaque, gold puddle lights, special interior lighting sequence, and a custom Signature key fob.
  • Performance Upgrades – Carbon-ceramic brakes with gold calipers
  • Bundled Luxe Package – Full Self-Driving (Supervised), four years of Premium Connectivity, free lifetime Supercharging
  • Performance Metrics – ~1,020 horsepower, sub-2-second 0-60 MPH, ~390-mile range

Tesla quickly introduced a No Resale Agreement for the Signature Editions of the Model S and Model X, which would penalize the seller for “the amount of $50,000 or the value received as consideration for the sale or transfer, whichever is greater.”

The company continues:

“If you sell or otherwise transfer the ownership of your Model S or Model X, the remainder of the Recommended Maintenance, Wheel and Tire Protection Plan, and Windshield Protection Plan will transfer automatically to the buyer. The Full Self-Driving (Supervised), Free Supercharging and Premium Connectivity will not transfer with the vehicle and will terminate once the ownership of the Model S or Model X is transferred.”

Tesla will likely come after the seller, especially as it has been about two months since Tesla launched deliveries.

Tesla Full Self-Driving v14.3.5 Early Impressions: new features and early performance

Tesla rolled out Full Self-Driving (Supervised) v14.3.5 yesterday, and about fifty miles of driving on the new version has given me enough time to highlight what seems to be strong about the release and what is not.

Additionally, Tesla has added a few new features with this specific update, which we’ll highlight as well.

Tesla Full Self-Driving v14.3.5 Performance

The new update is business as usual. Things seem to be running completely normal and necessary, but there are a few things that we’ve seemed to pick up on based on our own experience with v14.3.5, as well as what other users are seeing.

Initially, it seems to be more aware of its surroundings, making moves that are incredibly courteous to other drives and operating just a tad more reserved than what the suite might have done previously.

We had two instances where it showed this, the first being FSD needing to pass a Flagger Force vehicle that was placing down signage for the day. Their work truck was right at the front corner of a right-hand turn; typically where most cars travel when they take that turn.

FSD v14.3.5 recognized this, slowed down, and took the turn wide with no issues:

Additionally, v14.3.5 backed up for a semi truck that was making a wide turn onto a road my car was on. This is not new, but it seemed to be backing up for courtesy; it didn’t seem completely necessary, but it might have put some peace of mind in the truck driver’s head:

X user Mike P, also a Pennsylvania native like myself, shared three clips of his Tesla running v14.3.5 performing similar maneuvers. He said:

“FSD turns right into a small alley that only fits one car at a time, sees oncoming car, reverses out of alley to make space, realizes oncoming car is actually parking, re-enters alley.”
Check it out here:

It seems like Speed Profiles are still in need of some tweaking; I am adjusting what Speed Profile I’m in frequently, constantly changing it to get it to travel at the correct speed. This was an issue for me on v14.3.4. It seems like they’re just a little inconsistent.

Terrible Parking

Parking attempts on v14.3.5 were not good. There are quite a few people who have said this:

David Moss, the Tesla owner who has taken multiple coast-to-coast drives without any interventions, also has had some issues with parking early on with v14.3.5:

New Features

Tesla has added the ability to open Camera Preview at any time. Previously, it was only available in Park. Here’s what that feature looks like in action:

Check back later this week for a longer review of what we’ve noticed on Full Self-Driving v14.3.5.

Tesla makes the cut on California’s newest EV Rebate program

California just signed a $270 million EV rebate into law and it starts this summer.

California Governor Gavin Newsom signed SB 168 into law on Monday, July 13, 2026, creating a $270 million EV rebate program that delivers money directly at the dealership rather than as a tax credit applied months later. The program, called MyFirstEV, is funded equally by California’s state budget and participating automakers, with each contributing $135.5 million to make the math work.

The timing is directly tied to the loss of federal support when the $7,500 federal EV tax credit ended, removing the most significant consumer incentive that had driven EV adoption in the U.S. California, which accounts for roughly one-third of all EVs sold nationally, moved to fill that gap with a state-level replacement.

The rebate structure is straightforward. First-time EV buyers can receive $3,500 off any new battery-electric vehicle with an MSRP up to $50,000. Used EVs priced at $25,000 or below qualify for a $1,750 rebate. The credit is applied at the point of sale, which removes the friction of the old federal system where buyers had to wait for tax season to see the benefit. The program goes live later this summer, with the California Air Resources Board expected to release full participation details next month.

California hits Tesla Cybercab and Robotaxi driverless cars with new law

For Tesla buyers, the implications are mixed. The Tesla Model 3 RWD at $42,490 and the Model 3 Long Range at $47,490 both fall under the $50,000 cap and would qualify for the full $3,500 rebate for first-time buyers. The Model Y, which starts at $44,990 after Tesla’s recent price adjustment, also qualifies. The Model X, Model S, and Cybertruck all exceed the cap and receive no benefit. As Teslarati has reported, the program also includes a carve-out exempting California-based automakers like Rivian and Lucid from the price cap entirely, a provision that puts Tesla at a disadvantage since it relocated its headquarters to Texas in 2021.

Other qualifying vehicles include the Chevrolet Equinox EV, Ford Mustang Mach-E, Hyundai Ioniq 5, Kia EV6, and Volkswagen ID.4.
