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.

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.

If you look up ambient lights for Tesla, you'll see several ads for third-party light kits. Perhaps this is why Tesla added its own Ambient Lights feature to the new Model 3. So, let's get enlightened.

Tesla's ambient lights are thin light strips that are embedded in each of the vehicle's doors near the top edge. It also curves around the dashboard near the windshield, giving passengers a near 360-degree light effect.

Supported Models

Tesla new ambient light feature is available on the new Model 3 (2024+), and will be available on the Cybertruck in a similar manner. With a refresh ongoing for the Model Y, known as Juniper, it will likely also have ambient lights. That just leaves out the most luxurious flagship vehicles, the Model S and X, for now.

The Model S and Model X could be due for a minor refresh that would not only add ambient lighting, but also include a front-bumper camera that the Cybertruck has and the new Model 3 is expected to have in the near future.

The ambient light settings allow you to light up the interior in a color that reflects your mood or preference. Under Controls > Lights > Accent Lights, you are handed the freedom to choose virtually any color to adorn the interior of your Tesla.

You have control over whether the ambient lights are on, off, or set to an "Auto" setting, though not fully clarified, seems to promise intelligent lighting adjustments akin to our control over dome lights, offering a reduction in reflections during drives.

While the ability to control the brightness level seems missing, Tesla did include color presets, letting you curate a series of your favorite colors.

It should be noted that the changes are confined to the light strips on the doors and dash, steering clear of the footwell lights and other interior lighting.

Future Enhancements

With Tesla, we can be assured there will be enhancements to this feature in a future update. In fact, the Tesla community is already busy coming up with useful suggestions. Some owners thought Tesla should take advantage of the lighting to provide driver feedback, such as automatically changing the ambient lighting to a red hue when there's a vehicle in your blind spot. Tesla could also glow the light strip on a door if it's not closed properly, or use the lighting to provide feedback when Sentry Mode is enabled.

Other uses could be more fun, such as cycling the light through various colors when the 'Rainbow Road' easter egg is activated.

Ambient Lighting in Action

While the possibilities are endless and Tesla engineers will surely have fun coming up with creative uses for the feature, the biggest improvement we can hope for in the near future is the ability to adjust the light intensity.

Tesla Model 3 'Highland' Performance Details Discovered in European Documents

Tesla outdid itself with the refreshed Model 3, known as the Highland. Despite all the fantastic upgrades, something is missing - the Performance version or perhaps the Plaid. The letter "T" has shown up on vehicle certificates in Europe, and despite Elon Musk's sense of humor, it is unlikely this is a Mr. T reference.

Deciphering the 'T'

Diligent scrutiny of the European Type Certificate, issued by the Dutch vehicle authority RDW and shared on the TFF Forum, revealed a subtle yet pivotal alteration — including the letter 'T' in the eighth digit of the Model 3 Performance's VIN.

This seemingly minor detail, indicative of the vehicle's motor/drive unit type, sparked curiosity and speculation on the forum. Could it be a tri-motor setup to usher in a new Plaid version of the Model 3? This vehicle has already got endless amounts of zip, but three motors? May The Schwartz Be With You!

This could also explain the Model 3+ badging that was spotted during the Ministry of Industry and Information Technology (MIIT) in China inspection of the refresh. However, the regulatory filings highlighted just two distinct variants of the car: a rear-wheel drive (RWD) with a 194 kW motor and an all-wheel drive (AWD) dual-motor setup that combines to deliver a formidable 331 kW of maximum power.

Initial conjectures leaned towards the possibility of a tri-motor setup, drawing parallels with the Plaid variants of the Model S and Model X. However, a deeper dive into the certification document clarified that the Model 3 Performance retained its Dual Motor setup, dispelling the possibility of a tri-motor upgrade.

Strategic Enhancements: A Glimpse into Potential Upgrades

Given the documented specifications, it becomes plausible that Tesla has strategically enhanced one of the dual motors, potentially aligning it with the advanced motor found in the Model S/X Plaid. This modification is poised to augment the top-end speed and acceleration of the Model 3 Performance, addressing its comparative limitations in extended races against traditional gas-powered supercars.

Meanwhile, the Model 3 refresh has become the new Bigfoot of the roads of North America, with rare sightings posted on social media. However, it appears the continent is excluded from the initial launch of the Model 3 Highland. Internal communications within Tesla suggest North American enthusiasts might have to exercise patience until 2024.
