Tesla Cybertruck is perfect for Elon Musk’s dream HVAC system
Tesla CEO Elon Musk teased the idea of integrating its upcoming Cybertruck with a quiet and efficient HVAC system that’s also capable of distilling water. And while water distillation from a utility vehicle may seem overkill, it makes perfect sense to include such a feature in the futuristic stainless steel behemoth.
The idea became apparent during a conversation with Joe Rogan nearly two years ago, but the idea has since gained more traction. In a tweet that reiterated his desire for a “super-efficient, quiet home HVAC with HEPA & water distillation,” one of the CEO’s Twitter followers asked if he was more interested in developing the system than working on the Cybertruck. However, Musk answered by saying, “Maybe Cybertruck will have it…”
When Musk appeared on the Joe Rogan Experience Podcast in September 2018, he spoke of an intelligent home HVAC system that would only cool rooms that have people in them. This idea would increase efficiency and eliminate wasted energy throughout a home. However, it would seem that the Cybertruck may receive something along the same lines.
I’m dying to do super efficient, quiet home HVAC with HEPA & water distillation. It’s weird, but I really want to do it.

Maybe Cybertruck will have it …

Having an energy-efficient HVAC system bodes well for the Tesla Cybertruck, which aims to have long-range capabilities at an affordable price point. Also, considering the vehicle’s spacious interior cabin, having an efficient heating and cooling system would reduce range-robbing energy on something as large as the Cybertruck.
The Cybertruck will likely be Tesla’s most significant vehicle to date, leaving no doubt that the powerhouse truck can accommodate a HEPA filter. The installation of this filter keeps air quality within the cabin of the vehicle extremely high. Tesla’s “Bioweapon Defense Mode,” which the company developed to protect passengers from the dangers of environmental pollution, would also be a perfect fit for the upcoming vehicle.
But Musk’s vision for the Cybertruck goes far beyond the third rock from the sun. Perhaps its purpose is geared towards life on Mars, just as much as it is for Earth.
Musk’s narratives in the past have playfully hinted at survival during cataclysmic events, with the CEO emphasizing that Teslas run off of sunlight, which will be available for far longer than fossil fuels. But Elon’s playful jokes could be a hint at something more serious, like the inevitable destruction of Earth if pollution-producing forms of energy continue to be used as fuel.
The Cybertruck’s exoskeleton and robust stainless steel body actually make it ideal for a dangerous future. The pickup’s already durable build combined with range, speed, and sustainability could be a difference-maker for passengers even in otherwise risky events. An intelligent HVAC unit, an air filtration system, and a water distillation feature just makes the all-electric pickup an even better survival tool.
Tesla Cybertruck (pressurized edition) will be official truck of Mars

But Musk seems to believe each of these items could be added onto the Cybertruck, allowing it to operate anywhere, even if the location isn’t on Earth. After all, he did say the Cybertruck’s “pressurized edition” would be the official truck of Mars.
Perhaps the Cybertruck, when paired with Bioweapon Defense Mode, an HVAC unit, and a water distillation feature, could be one of the vehicles of choice for people when things on Earth start going south due to the climate crisis.
Protecting the passengers in the car has always been a goal of Tesla, but the purpose goes much further than accident and collision safety. Musk has made several attempts to improve the air purification systems within the cars, for example, an aspect of safety that is rarely explored by traditional automakers. “Air quality has a much bigger effect on health than people realize,” he said.
The Cybertruck’s mission is likely to protect people from accidents and dirty air. The vehicle’s future could be a large part of Musk’s “Master Plan,” which entails a push towards sustainability. But beyond Earth, the priorities of Tesla will still apply. On Mars, people will surely need clean air, protection from harmful rays, and a water source. The Cybertruck just happens to be a great vehicle to provide all that, and more.

Tesla Roadster’s new patent preps white-knuckle speeds, keeping it grounded
Ahead of its highly anticipated unveiling, Tesla’s upcoming Roadster received a new patent that aims to keep it grounded while enabling white-knuckle speeds.
The patent, which was granted on September 29, is titled “Electric Car Fan,” bluntly stating its design but not its purpose, which is further detailed in the text of the application. Interestingly, it comes two weeks before the Roadster event, which was delayed due to unfavorable weather on Thursday, which could cause issues, as Tesla revealed the event must be held outdoors.
🚨 The design uses electrically driven ducted fans, typically shown as a row of four at the rear, powered by the vehicle’s high-voltage battery.
The fans pull air from an underbody inlet, route it through ducts, and expel it from a larger rear outlet that functions as a… https://t.co/CHQB9u9UA3 pic.twitter.com/QVXmWTdggh

The purpose is to solve a problem that is relatively unique to high-performance electric cars. Instant motor torque is useless if the tires cannot plant that force, and conventional wings and underbody tunnels generate downforce only when air is already rushing past the car. At launch, in slow corners, and under hard braking from modest speed, passive aerodynamic additions contribute essentially very little to downforce.
Tesla’s filing says that its fans can produce the downforce needed, independent of vehicle velocity, then ease off so the same hardware does not pile on drag at highway speeds, an issue that can come from excessive body modifications.
The hardware outlined in the patent is a ducted-fan package that is placed into the rear of the vehicle. An underbody inlet between the rear wheels feeds a duct that rises to a wide outlet in the diffuser. In that outlet are four axial fans, which are divided by vertical strakes. They will pull air from under the floor and press the chassis onto the pavement.
The language in the patent claims it can cut drag rather than add to it while simultaneously increasing downforce.
Tesla Roadster event requires restricted airspace, and the FAA obliges
The fans run from the high-voltage battery and a vehicle control system, so output can be modulated rather than left on as a fixed penalty.
There are additional strengths that can come from this design, like extra tire load at low speed, which can contribute to even more face-melting acceleration rates, decrease stopping distance, and sharper turn-in before a wing has air to work with. Adjustable fan speed lets the car add grip only when needed, so it can be catered to the force of a turn or acceleration.
These designs were previously used, and banned, in some competitive settings. The Brabham BT46B was banned in F1 competition for using a similar fan design and being labeled as too effective.
Tesla still lists the Roadster as having a sub-two-second 0-60 MPH time and a 250-plus-MPH top speed, and there are expectations for a SpaceX cold-gas thruster package that could not only increase acceleration but potentially cause the vehicle to hover.
It is important to note that a patent is not a production part, and packaging four fans in a rear diffuser, managing noise, and potential debris are all things Tesla must consider. With that being said, the patent being granted shows Tesla is designing the Roadster to go fast, but it is also attempting to use unique strategies to combat any issues it might have at those speeds.

Tesla showrooms picked clean ahead of Q3 end as demand looks strong
Tesla (NASDAQ: TSLA) showrooms have been picked clean ahead of the end of the third quarter of the year, as demand looks to be strong and delivery estimates for new vehicles are pushed into late 2026 and early 2027.
Tesla appears to have sold out of many of its Model 3 and Model Y trim levels in the United States, as only the Model Y RWD and Model Y All-Wheel-Drive are available for delivery before the end of the year.
Additionally, many showrooms are either completely empty or void of all but just one demo unit within the buildings themselves in an effort to bolster what could be one of Tesla’s best quarters in vehicle deliveries in recent memory.
I’m at Tesla right now and when I walked into their showroom I was shocked to see it basically empty.
I asked one of the people working there where all of the cars are “Gone – it’s the end of the quarter and we’ve sold out of everything… including the display vehicles”So… pic.twitter.com/rN7s3gE6sJ

All the cars are gone from Tesla Century City!
All they have is Model Y L, a self-driving video playing on the background. I guess the best product is no product. Either that or they just sold the showroom cars. pic.twitter.com/mzCjWaXwww

Show room is empty. I asked and they have sold the demo cars too. Delivery numbers better be outstanding! pic.twitter.com/jq5N28Q6tZ

Additionally, when I spoke to the guys at Tesla Mechanicsburg two weeks ago, when I returned the Model Y L, their third hauler of the week had just arrived, and every vehicle on it, along with every vehicle in their delivery lot, was accounted for and had a name attached to it for delivery.
Talking to the guys at the Mechanicsburg showroom on Friday, they couldn’t believe they had ANOTHER hauler coming in of cars for delivery—and each was accounted for
No car just sitting in inventory. They’re expecting a BIG quarter, and this is more than just the Y L https://t.co/ce801GkKVv

Tesla saw a 25 percent increase in deliveries in Q2 compared to the same quarter the year before. The vast majority of the 480,126 units it delivered, 467,762 vehicles to be exact, were the Model 3 and Model Y.
In Q3 2025, Tesla delivered 497,099 vehicles, once again a figure that was dominated by the company’s two mass-market vehicles. Analysts have unusually wide predictions for this quarter, likely because so many firms missed the Q2 delivery figure by such a substantial margin; Wall Street predicted 408,000 cars, while Tesla delivered 480,000.
Goldman Sachs has Tesla slotted for 435,000 deliveries in Q3, while JPMorgan said it anticipates 482,000. The median guess is about 449,000 deliveries for Q3.

Watch Tesla’s “guardian angel” FSD feature take over for collision evasion
Tesla’s Automatic Collision Evasion feature can be seen in one of the first owner videos of it in action.
Tesla owner Spencer (@scotsrule08) posted on Monday that the feature “worked flawlessly,” saying FSD reengaged itself just as he was about to hit a curb. Ashok Elluswamy, who leads Tesla’s AI team, shared the clip and wrote, “A guardian angel always looking out for you.”
The video arrives in the middle of a staged rollout. Tesla first shipped Automatic Collision Evasion with FSD (Supervised) v14.3.9 in software update 2026.27.6 earlier this month, which Teslarati covered as it reached cars. Update 2026.27.10, which began going out on September 19, carried the feature improvements with FSD v14.3.10, according to release notes tracked by Not a Tesla App. The newer 2026.27.11 build is now reaching another wave of vehicles.
The new Automatic Collision Evasion feature worked flawlessly! FSD reengaged itself just as I was about to hit a curb.
Kudos @Tesla_AI team! 👏 pic.twitter.com/Fbp15HhpL2
— Spencer (@scotsrule08) September 28, 2026
The feature only runs on HW4 vehicles, and it requires an active FSD purchase or subscription with both FSD (Supervised) and Automatic Emergency Braking enabled. HW3 owners receive FSD v14.2 Lite in the same updates, but that build does not include collision evasion.
Tesla’s release notes describe two triggers. The first is an imminent frontal collision that braking alone may not prevent, in which case the car can activate FSD to steer, brake or accelerate around the hazard. That scenario is limited to highways below 85 mph, with no pedestrians or cyclists detected and no slippery road surface. The second covers a driver who appears inattentive, such as reaching into the back seat, or who seems to have switched off FSD by accident. Spencer’s curb clip appears to fall into that second category.
Tesla plans big safety improvements for Full Self-Driving v15
Once the system takes over, the accelerator is muted and light brake input will not cancel the maneuver. Drivers need to apply firm, deliberate steering force to take back control, and the car chimes to hand control back once the danger has passed.
Elluswamy recently noted that earlier hazard prediction, faster reaction time and better collision avoidance would arrive with FSD v15, the next major version.
