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.

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.

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 and Musk Lobby for Unified Federal Autonomy Rules Ahead of Robotaxi Debut

By Karan Singh

With Tesla’s Robotaxi network poised for its initial launch as soon as June 12th, Elon and Tesla’s lobbying team are stepping up to speak to administrators about autonomy regulation. According to a report from Bloomberg (paywall), the team is working on a behind-the-scenes push in Washington to establish a federal framework for autonomous vehicles.

This push involves direct lobbying of members of the US Congress to build a clear legislative path for autonomy, and the timing is no coincidence. Tesla needs clear regulations to operate under, rather than the fractured state-by-state or city-by-city regulations that exist sporadically throughout the US.

Pushing for a National Standard

The report, citing insiders familiar with the matter, details that Elon has been personally involved in calls with legislators and has been weighing in on revisions to the bill introduced on May 15th, which aimed to establish a basic regulatory framework for autonomous vehicles. Tesla’s goal is to move this bill forward before Congress’s July 4th recess.

When the US Transportation Secretary visited Tesla earlier in May, Elon had some wise words to say on this topic, touching on the core issue: for a service to operate nationwide, navigating a patchwork of regulations is a legal and operational nightmare.

It’d be wonderful for the United States to have a national set of rules for autonomous driving as opposed to 50 independent sets of rules on a state-by-state basis. - Elon Musk

Federal Rules

While the initial Robotaxi pilot launch in Austin is more than feasible under Texas’s relatively permissive regulations, the long-term vision is severely hamstrung by federal rules. Current regulations only permit special exemptions for a test fleet of up to 2,500 vehicles that lack traditional controls, such as a steering wheel and pedals.

While this isn’t a direct roadblock for Tesla’s initial deployment of Model Ys in the Robotaxi network, this vehicle cap is a roadblock for the mass production and deployment of Tesla’s purpose-built Cybercab. The Cybercab, with its easy-to-clean interior, relatively low cost, and lower-maintenance design, is ideal to scale the service with a vehicle designed from the ground up to be autonomous, where it’ll be cheaper to operate and maintain. Remember that the Cybercab is expected to be capable of 5.5 miles per kWh, whereas the Model Y is capable of about 4. Tesla needs a federal law that allows for the widespread sale and operation of the Cybercab, as it’ll likely be crucial to make the network profitable.

The legislative push also comes as Tesla is coming under increasing scrutiny from regulators. The NHTSA is already probing Tesla’s Robotaxi plans and seeking answers about FSD’s performance in adverse weather conditions.  Establishing a clear, Congressionally approved federal framework will not only create a more predictable and stable regulatory environment for Tesla to operate in, but it’ll actually make these vehicles safer by having one set of rules.

Difficult Road

This isn’t the first crack at creating national autonomous vehicle laws from Congress. Various bills have been attempted over the years, with one even passing the House in 2017 before getting stalled and dropped in the Senate. The primary obstacle has often been debates over legal liability and pressures from legal groups who have raised concerns about handling incidents with autonomous vehicles.

The new bill represents the latest effort to clear the maze of red tape, and Tesla’s direct involvement, along with the upcoming pilot launch of the Robotaxi network, provides some momentum to push this forward.

Tesla is on the verge of launching Robotaxi, which has massive implications for how we approach urban mobility as a society. However, just as in many other cases, the technology is advancing far faster than the glacial pace of bureaucracy, which means that lobbying is crucial to expedite the process of getting regulations in place as soon as possible.

Tesla Launches Model 3 Performance Projection Lights

Tesla has added another touch of customization, and this time for the owners of the 2024+ refreshed Model 3 Performance. Tesla is launching another set of puddle projection lights. These new puddle lights will illuminate the ground with a colorized Model 3 Performance emblem when the doors are opened.

Puddle Projection

This accessory adds a touch of personalization to the door light, similar to the options already available for the original and refreshed Model Y, which projects the Tesla wordmark, as well as for the Cybertruck, which projects the Cybertruck logo. However, this one, in particular, is a little different because it’s the first option that includes color. It projects a crisp blue and white Performance logo onto the ground below the door.

The lights are sold in a pack of two, similar to Tesla’s options for other vehicles. These lights are usable for both the front and rear doors, which means you’ll need two sets if you want to do all four doors of the vehicle.

Interestingly, while the physical form factor of these lights means they would fit any Model 3, Tesla is explicitly stating these are exclusively for 2024+ Model 3 Performance vehicles. This means that, at least for now, purchases through the official Tesla Shop are restricted to owners with a refreshed Model 3 Performance VIN. In general, you should be able to use these on any Model 3 or Model Y, as the size of the projector and the power attachment point are the same for all these vehicles.

Installation is simple and is to be completed by the customer. Tesla does offer a page on their DIY service manual on how to get them installed. You'll need a blunt plastic tool to remove them from the door and to detach the power adapter from the original puddle lights.

The Model 3 Performance Projection Lights are priced at $75 USD in the United States and $125 CAD in Canada. They will likely become available within the coming weeks for the European and Asia-Pacific markets as stock becomes available globally.

Tesla recently also added a Tow Package for the new Model 3 in North America for the first time.
