Elon Musk confirms New Tesla Model S HVAC update for extra-quiet cabin
The Tesla Model S Plaid is filled to the brim with a ton of new features, from a rear display that streams media content to a steering yoke that brings a racecar-like experience to driving. The Model S Plaid also came with a number of updates for its cabin, particularly when it comes to noise cancellation.
As could be seen in the Model S Plaid Owner’s Manual, the newly-released flagship car is fitted with Active Noise Canceling Microphones, which are located in the front seats. The microphones detect the amount of external road noise that can be heard inside the cabin, which are then canceled out by noise canceling sounds that are played through the speakers. This setup allows a minimal amount of road noise to enter the cabin.
Tesla notes in the Model S Plaid Owner’s Manual that the vehicle’s Active Noise Canceling Microphones may not be available at the vehicle’s delivery. Yet despite this, a demonstration from Model 3 owner and YouTube host Tesla Raj has shown that even in its current state, the Model S Plaid’s cabin is already capable of canceling out a significant amount of noise.
New HVAC firmware coming soon that will make it quieter
— Elon Musk (@elonmusk) June 16, 2021
Responding to the demonstration, Tesla CEO Elon Musk remarked that the company would be rolling out a new HVAC firmware that would make the cabin even quieter. Musk may be pertaining to the activation of the Model S Plaid’s Active Noise Canceling Microphones in his post. With these components activated, the Model S Plaid could become a vehicle with one of the quietest cabins in the market.
Elon Musk did not only mention an improvement for the Model S Plaid’s HVAC system. He also provided some updates on Tesla’s upcoming home HVAC system. According to Musk, it would be great if Tesla could create a home HVAC system that is “super energy efficient, quiet & purifies the air.” He added that Tesla has already developed such a system for its vehicles, so it’s only a matter of scaling up the product for home use.
Most people have no idea just how good the Tesla air purification system is. Literally 10X better than any other car.

Musk was not exaggerating when he stated that Tesla’s air purification system is formidable. Tesla’s Bioweapon Defense Mode, which was initially rolled out to the Model X and later introduced for the Model S and the Made-in-China Model Y, has been proven to help keep the air inside the vehicle clean despite bad conditions outside. Over the years, Model S and Model X owners have sworn by the feature, noting that Bioweapon Defense Mode is strong enough to clean the air from even the most polluted areas.

Tesla teases new market entrance with confusing and cryptic message
Tesla teased its entrance into a new market with a confusing and what appeared to be cryptic message on the social media platform X.
The company has been teasing its entrance into several markets, including Africa, which would be a first, and South America, where it only operates in Chile.
In September, Tesla started creating active job postings for the Colombian market, hinting it would expand its presence in South America and launch in a new country for the first time in two years.
The jobs were related to various roles, including Associate Sales Manager, Advisors in Sales and Delivery, and Service Technicians. These are all roles that would indicate Tesla is planning to launch a wide-scale effort to sell, manage, and repair vehicles in the market.
Last night, Tesla posted its latest hint, a cryptic video that seems to show the outline of Colombia, teasing its closer than ever to market entry:

This would be the next expansion into a continent where it does not have much of a presence for Tesla. Currently, there are only two Supercharger locations on the entire continent, and they’re both in Chile.
Tesla will obviously need to expand upon this crucial part of the ownership experience to enable a more confident consumer base in South America as a whole. However, it is not impossible, as many other EV charging infrastructures are available, and home charging is always a suitable option for those who have access to it.
Surprisingly, Tesla seems to be more concerned about these middle-market countries as opposed to the larger markets in South America, but that could be by design.
If Tesla were to launch in Brazil initially, it may not be able to handle the uptick in demand, and infrastructure expansion could be more difficult. Brazil may be on its list in the upcoming years, but not as of right now.

Tesla expands crucial Supercharging feature for easier access
It is a useful tool, especially during hours of congestion. However, it has not been super effective for those who drive non-Tesla EVs, as other OEMs use UI platforms like Google’s Android Auto or Apple’s iOS.
Tesla has expanded a crucial Supercharging feature that helps owners identify stall availability at nearby locations.
Tesla said on Tuesday night that its “Live Availability” feature, which shows EV owners how many stalls are available at a Supercharger station, to Google Maps, a third-party app:

Already offering it in its own vehicles, the Live Availability feature that Teslas have is a helpful feature that helps you choose an appropriate station with plugs that are immediately available.
A number on an icon where the Supercharger is located lets EV drivers know how many stalls are available.
It is a useful tool, especially during hours of congestion. However, it has not been super effective for those who drive non-Tesla EVs, as other OEMs use UI platforms like Google’s Android Auto or Apple’s iOS.
Essentially, when those drivers needed to charge at a Supercharger that enables non-Tesla EVs to plug in, there was a bit more of a gamble. There was no guarantee that a plug would be available, and with no way to see how many are open, it was a risk.
Tesla adding this feature allows people to have a more convenient and easier-to-use experience if they are in a non-Tesla EV. With the already expansive Supercharger Network being available to so many EV owners, there is more congestion than ever.
This new feature makes the entire experience better for all owners, especially as there is more transparency regarding the availability of plugs at Supercharger stalls.
It will be interesting to see if Tesla is able to expand on this new move, as Apple Maps compatibility is an obvious goal of the company’s in the future, we could imagine. In fact, this is one of the first times an Android Auto feature is available to those owners before it became an option for iOS users.
Apple owners tend to get priority with new features within the Tesla App itself.

Elon Musk’s Boring Co goes extra hard in Nashville with first rock-crushing TBM
The Boring Company’s machine for the project is now in final testing.
The Boring Company is gearing up to tackle one of its toughest projects yet, a new tunnel system beneath Nashville’s notoriously tough limestone terrain. Unlike the soft-soil conditions of Las Vegas and Austin, the Music City Loop will require a “hard-rock” boring machine capable of drilling through dense, erosion-resistant bedrock.
The Boring Company’s machine for the project is now in final testing.
A boring hard-rock tunneling machine
The Boring Company revealed on X that its new hard-rock TBM can generate up to 4 million pounds of grip force and 1.5 million pounds of maximum thrust load. It also features a 15-filter dust removal system designed to keep operations clean and efficient during excavation even in places where hard rock is present.
Previous Boring Co. projects, including its Loop tunnels in Las Vegas, Austin, and Bastrop, were dug primarily through soft soils. Nashville’s geology, however, poses a different challenge. Boring Company CEO and President Steve Davis mentioned this challenge during the project’s announcement in late July.
“It’s a tough place to tunnel, Nashville. If we were optimizing for the easiest places to tunnel, it would not be here. You have extremely hard rock, like way harder than it should be. It’s an engineering problem that’s fairly easy and straightforward to solve,” Davis said.
Nashville’s limestone terrain
Experts have stated that the city’s subsurface conditions make it one of the more complex tunneling environments in the U.S. The Outer Nashville Basin is composed of cherty Mississippian-age limestone, a strong yet soluble rock that can dissolve over time, creating underground voids and caves, as noted in a report from The Tennessean.
Jakob Walter, the founder and principal engineer of Haushepherd, shared his thoughts on these challenges. “Limestone is generally a stable sedimentary bedrock material with strength parameters that are favorable for tunneling. Limestone is however fairly soluble when compared to other rack materials, and can dissolve over long periods of time when exposed to water.
“Unexpected encounters with these features while tunneling can result in significant construction delays and potential instability of the excavation. In urban locations, structures at the ground surface should also be constantly monitored with robotic total stations or similar surveying equipment to identify any early signs of movement or distress,” he said.
