Tesla is known for its advanced technology and innovative features, and 'Bioweapon Defense Mode' is one of those features. With increasing concerns about air pollution worldwide, this advanced air filtration system demonstrates Tesla's commitment to passenger safety and well-being.

What is Bioweapon Defense Mode?

Bioweapon Defense Mode is a state-of-the-art air filtration system designed to protect vehicle occupants from various air pollutants, including exhaust fumes, smoke, allergens, airborne pathogens, and other potentially hazardous particles. This feature uses a High-Efficiency Particulate Air (HEPA) filter, capable of capturing 99.97% of particles as small as 0.3 micrometers in diameter, and a secondary filtration system with activated carbon filters to remove odors, gases, bacteria, viruses, pollen, and mold spores.

Tesla's Inspiration and Development of Bioweapon Defense Mode

Tesla's commitment to protecting passengers from air pollution goes beyond merely producing electric vehicles to contribute to a cleaner environment. Tesla CEO Elon Musk has credited Google co-founder Larry Page for inspiring him to develop a more powerful air filtration system for Tesla vehicles. The idea is not only to reduce local air pollution but also to minimize the direct impact of air pollution on the occupants of Tesla vehicles.

How Does Bioweapon Defense Mode Work?

The HEPA filter in Bioweapon Defense Mode is inspired by air filtration systems used in hospitals, clean rooms, and the aerospace industry. When activated, the climate control system pulls in outside air and filters it through the HEPA filter and secondary filtration system. This process effectively removes harmful particles and contaminants from the air.

In addition to the filtration process, Bioweapon Defense Mode creates a positive-pressure environment inside the cabin. This feature, borrowed from hospital settings, prevents outside air from leaking into the vehicle. The result is an air-tight cabin that continuously filters and circulates clean air to protect passengers from pollutants, pathogens, and allergens.

Which Tesla Models Have Bioweapon Defense Mode

Tesla introduced the HEPA filter and Bioweapon Defense Mode in 2016 on the Model X and Model S with the new front fascia. As of 2020, Bioweapon Defense Mode also became standard on Model Y. Tesla could not include the large HEPA filter required for the Bioweapon Defense Mode in Model 3 due to space constraints. However, the bigger Model Y does have enough space to accommodate the filter. Tesla initially introduced the filter and Bioweapon Defense Mode in electric SUVs produced in China and later made it a standard feature in all Model Y vehicles produced.

How to Check If You Have Bioweapon Defense Mode

Tesla owners can confirm whether their vehicle is equipped with Bioweapon Defense Mode by opening the HVAC control screen and looking for the biohazard symbol. If the vehicle is equipped with Bioweapon Defense Mode, there will be a biohazard icon located near the top right of the screen, next to the recirculation icon. If the symbol is present, the vehicle has the feature.

How to Turn On Bioweapon Defense Mode

You can activate Bioweapon Defense Mode from within your car or through the Tesla mobile app.

To activate it within the car, go to the climate control screen and tap the biohazard symbol. The vehicle will immediately start using air from outside the vehicle and running it through its HEPA filter.

To enable the filter from your Tesla app, you can go to the Climate section then swipe up from the bottom. This will reveal several options, including Bioweapon Defense Mode.

Bioweapon Defense Mode Retrofits

For Model S and Model X owners without the HEPA filter, Tesla offers a retrofit option for $500, which includes shipping and installation at a Tesla service center.

Tesla does not offer an official retrofit for for the Model Y, although some owners have shown that it is possible through a DIY solution.

Scientific Testing of Tesla's Bioweapon Defense Mode

When Tesla first introduced the Bioweapon Defense Mode in the Model X in 2015, the company released test results with particulate matter 2.5 air quality readings. The results showed that the system significantly improved air quality when needed. This further validates Tesla's claims about the effectiveness of its advanced air filtration system in protecting passengers from air pollution and other harmful particles.

Demonstrating the Effectiveness of Bioweapon Defense Mode

Tesla has conducted experiments (video below) to demonstrate the effectiveness of its HEPA filtration system and Bioweapon Defense Mode. In one such experiment, a Tesla Model Y and a BMW X3 were parked inside a giant bubble, and smoke bombs were detonated. The Model Y had Bioweapon Defense Mode activated, while the BMW X3 relied on its standard filtration system.

During the experiment, a Tesla employee sat in the driver's seat of the Model Y to showcase the company's confidence in its product. The video showed that the cabin of the Model Y remained free from red smoke, while the interior of the BMW X3 was invaded by it. After the experiment, Model Y's activated carbon filters and HEPA filters were removed, revealing that they had captured a significant amount of red dust.

The filtration system is active whenever climate control is pulling in outside air. In extreme conditions, users can activate Bioweapon Defense Mode, which positively pressurizes the vehicle’s cabin, preventing pollutants from leaking. All air is filtered through the HEPA and gas media filters in this mode.

The Importance of Air Quality in Vehicles

Air pollution is a global issue, and prolonged exposure to air pollutants, such as when stuck in traffic, can have significant health effects, including respiratory and cardiovascular issues. With more time spent in vehicles, ensuring that the air inside the cabin is clean and safe for passengers is crucial. Tesla's Bioweapon Defense Mode addresses this concern by providing a superior air filtration system that reduces exposure to harmful pollutants. This feature not only contributes to the overall well-being of passengers but also sets Tesla apart from other automakers who may not offer such advanced air filtration systems.

Comparison with Other Automakers

While other automakers offer air filtration systems in their vehicles, few can match the level of protection provided by Tesla's Bioweapon Defense Mode. For instance, the BMW X3, which was used in the previously mentioned experiment, does not offer a feature similar to Bioweapon Defense Mode. The experiment highlighted the stark contrast between Tesla's advanced air filtration system and the standard filtration systems found in other vehicles, emphasizing Tesla's commitment to innovation and passenger safety.

Tesla's Bioweapon Defense Mode is a groundbreaking feature demonstrating the company's dedication to passenger safety and well-being. By offering an advanced air filtration system capable of protecting occupants from various air pollutants, Tesla sets itself apart from other automakers in the industry. As air quality continues to be a significant concern worldwide, the Bioweapon Defense Mode is a valuable asset for Tesla owners, ensuring they can breathe clean and safe air inside their vehicles.

Tesla Holiday Update Wishlist - Maps & Autopilot Edition

By Not a Tesla App Staff
Not a Tesla App

We’re eagerly anticipating Tesla’s biggest update of the year — the Holiday update. The update usually arrives in December, typically towards the end of the month. Last year, the rollout was actually earlier, happening in the second week of December.

As part of our ongoing series, we’re sharing our wishlist for features we hope to see in this year’s holiday update. This edition focuses on improvements to Tesla Maps and Autopilot.

User-contributed Map Data

Many users have asked for the integration of more Waze-like features into Tesla’s navigation. Earlier this year, Tesla added Speed Camera locations, traffic lights and stop signs to maps, but users really want it to be a Waze-like experience that lets you contribute data. This includes marking police car locations, accidents, construction, and more. We’re not sure how likely this is to happen. So far, Tesla has relied on the Google API and other vendors to highlight information on the map.

Avoid Highways Option

Users have been asking for an ‘Avoid Highways’ option forever as it’s a standard option in navigation systems nowdays. While the Alternate Routes feature is helpful, it may not always provide a route that avoids the highway.

In June, Elon Musk confirmed that a “Avoid Highways” option would be added to Tesla navigation. We still haven’t seen it arrive, but we’re fairly confident that it will eventually be available in Tesla vehicles, maybe even for the Holiday update. What better way to enjoy a winter wonderland than to drive through some country roads instead of on the highway?

3D Buildings in Maps

Not a Tesla App

3D maps arrived in China earlier this year, and Google began rolling out 3D maps for various apps just last month. Apple already provides a 3D map with beautiful renderings of nearby buildings, and Rivian already features 3D buildings with an Apple-like look, so Tesla is playing catch-up a little bit here.

While 3D map support could be viewed as mostly eye candy, it can sometimes be useful when navigating an unknown area. Since the Intel infotainment processor is already near its limit and has excluded features in the past, such as improved visualizations and High Fidelity Park Assist, this feature could be limited to newer AMD-powered vehicles.

At Tesla’s recent Robotaxi event, we saw custom 3D maps in the vehicle with a specialized interface, so Tesla knows this is an appealing addition.

Detect and Visualize Emergency Vehicles

Greentheonly/X

Tesla already detects emergency vehicles while on Autopilot, however, it doesn’t display them in the visualization any differently than a normal car. Tesla was planning on adding emergency vehicle visualizations as far back as 2021, but they didn’t happen for some reason.

Tesla recently announced that they’re going to step up emergency vehicle detection by not only detecting the vehicles visually but also using audio input as a cue. With FSD v13, which is expected to be released to Tesla employees this month, FSD will detect emergency vehicles using the vehicle’s internal microphone. This should let the vehicle know about emergency vehicles sooner. We’re hoping that on-screen visualization comes along with this update.

If it’s anything like Tesla’s 2021 implementation, Tesla will design emergency lights that could be added to various existing 3D models, such as cars, SUVs, and motorcycles.

FSD Visualizations in Other Regions

This one is long overdue, and we hope it finally arrives. Owners outside of North America have been paying for FSD for years and have almost nothing to show for it. Sure, it includes some features like Summon (with USS vehicles) and, more recently, Autopark, but it doesn’t even include Actually Smart Summon yet.

While Tesla says the FSD is coming to Europe and other markets in Q1/Q2 next year, it’d be a great addition to add FSD visualizations for the time being.

There’s no doubt that Tesla is already detecting objects and vehicles behind the scenes and comparing what the vehicle would do to what the driver does to help improve Autopilot in these markets. For some reason, Tesla has decided to show different visualizations depending on whether you have Autopilot or FSD and whether you live in North America or elsewhere.

Adding FSD visualizations for everyone, regardless of whether they have Basic Autopilot, EAP, or FSD, would be an exciting addition — and it may even increase the subscription rate to FSD.

Expand Basic Autopilot

Tesla’s Basic Autopilot includes Adaptive Cruise Control and Autosteer, but we’d love for Tesla to expand this further to match what other manufacturers are offering.

Right now, Tesla considers Navigate on Autopilot and automatic lane changes part of Enhanced Autopilot. This means that if you’re on Autopilot and want to change lanes, you need to disable AP, change lanes, and re-enable it. Since many regions no longer offer Enhanced Autopilot for purchase, users are forced to put up with this annoyance or pay for FSD, which isn’t offered as a subscription outside of North America.

By creating a clearer distinction between Autopilot (focused on highway driving) and FSD (designed for city driving), Tesla could improve the Autopilot experience for users while encouraging them to upgrade to FSD.

Actually Smart Summon

Actually Smart Summon is still mostly limited to North America, with some small regions such as Taiwan, also receiving it. However, it still requires you to hold the ‘come’ button currently. The next big leap would be to remove this requirement and enable users to summon their vehicles with a single tap. Tesla previously said this was coming in a future improvement to A.S.S.

Ideally, we’d see the reach of Actually Smart Summon expanded to Europe and other regions and improvements of the feature, although we’re much more likely to see the former for the Christmas update.

Cybertruck is also still waiting for Summon, so this could be an additional surprise.

Autoshift for All Cars

While Autoshift isn’t directly tied to Autopilot, it does leverage AI to decide whether to shift into reverse or drive. This feature has now been released on the new Model S, Model X, the new Model 3, and the Cybertruck. However, Musk once said that it would be added to all Tesla vehicles, so we’re hoping that’s still in the works.

There’s certainly no reason why Tesla can’t add it to older vehicles with stalks. For those not familiar with Autoshift, it allows the vehicle to automatically shift into reverse or drive when the driver is ready to start moving. This makes it even easier to get going: You simply get in the car, press the brake pedal, giving the vehicle a chance to shift, and then press the accelerator.

This is our second wishlist of features we’d love to see in Tesla vehicles this holiday season. If you haven’t seen our first wishlist, the Tesla App Edition, be sure to check it out.

While this is a list of the most popular user requests related to Tesla’s navigation and Autopilot features, we’re sure that there are some we missed. Let us know your thoughts and ideas in our forums.

Tesla Cybertruck November Update: No More Wraps, New Crossbars Accessory, Available in Inventory, and Faster Charging

By Karan Singh
Not a Tesla App

There’s been a spade of Cybertruck announcements that just came up all at once, so let’s see what the polygonal truck is up to in the month of November. We’ve got a variety of topics to cover, starting with some disappointing news about Tesla’s in-house wrapping services, which are being discontinued for the Cybertruck. But don’t worry — there’s plenty of good news to follow.

No More Tesla Wraps

Tesla no longer offers wraps for the Cybertruck as an option for US customers. Tesla began wrapping vehicles earlier this year but stopped offering wraps for the Cybertruck as of November 13th.

This comes after Tesla previously reduced the color options for Cybertruck wraps from seven to five. However, this isn’t too big of an issue—there are plenty of companies that specialize in vehicle wraps.

The reason Tesla stopped offering wrap services for the Cybertruck isn’t clear. Was there not enough demand? Did it take up too much time from technicians who are already stretched thin?

Given the long repair backlogs in the United States, it makes more sense to have service technicians focus on vehicle repairs rather than spending time wrapping cars.

Inventory Foundation Series

The Cybertruck Foundation Series is now available as an inventory vehicle in certain locations in the United States. That means you can pick up a Foundation-series truck with little to no delay.

Only a few trucks are currently in stock, but this will likely expand as Tesla continues to ramp production and begins to offer the non-Foundation Series trucks as inventory vehicles.

These inventory vehicles are only available in the United States. Canadian owners will still need to put down a deposit for a Foundation Series Cybertruck to get it soon.

Crossbars

Tesla has just announced it is offering a new set of crossbars for the Cybertruck. With a load rating of 200 lbs, it’s on par with roof racks for other trucks. These crossbars also come with mounting pads and quick releases. There are also slots for attaching ski racks, bike racks, or even cargo boxes, letting owners expand the truck's storage capacity.

Interestingly, the Foundation Series trucks can install the crossbars over the cabin or the truck bed, while the non-Foundation Series can only mount the crossbars over the truck bed. That isn’t the greatest news - because one of the best uses for these crossbars is protecting the cabin glass when you’ve got items like long wooden planks hanging over the roof of the truck. Maybe we’ll see more on this soon.

Update: It turns out that you can, in fact, install the crossbars anywhere on a non-Foundation series vehicle. You’ll just have to pay for an additional roof applique, according to Wes Morril, Lead Engineer of the Cybertruck Program.

Faster Charging

Tesla announced updated versions of the V4 Supercharger, with a more powerful electrical cabinet that can charge the Cybertruck at up to 500kW. That’s an insanely fast speed—nearly 1,300 mi/hr of charging. This will come as part of a future update for the Cybertruck and as V4 Supercharger stations begin to be deployed.

That’ll make the Cybertruck the fastest-charging Tesla - even with its enormous battery.
