This is a preview from our weekly newsletter. Each week I go ‘Beyond the News’ and handcraft a special edition that includes my thoughts on the biggest stories, why it matters, and how it could impact the future.
Tesla has tapped a new type of automotive glass from supplier AGP for the Plaid Model S, invoking the thought that everything, even the finest details of the vehicle, was considered a possible improvement for the company’s rebirth of the all-electric, flagship sedan.
Many months ago, Teslarati stumbled across a list of Tesla’s suppliers through international connections. These suppliers were shipping massive volumes of whatever product they were giving to Tesla on cargo ships, and we noticed that there was a company called AGP that was shipping windshields and other automotive glasses to the company’s Fremont Factory.
It turns out that AGP has been providing Tesla with automotive glass for several years. Back in 2016, AGP provided glass for the Model X’s panoramic roof and windshields. However, Tesla utilized AGC Automotive’s windshields for its cars, according to Investopedia.
AGP is a Peru-based company that specializes in all types of automotive glass, but what they’ve done for Tesla is especially interesting. The company has been in business for 50 years, but just like everything else, it changes, and the automotive industry is no different. As electric vehicles have become more mainstream, technologies surrounding the development of these new, sustainable automobiles are popping up left and right. AGP’s eGlass for electric and autonomous vehicles is no different.
Now, AGP says on its website that it collaborates “closely with the companies that are leading the new wave of the electric and autonomous vehicles of tomorrow.” When I first stumbled across AGP many months ago on the cargo ship list for Tesla, there was no indication that there was an official partnership, so I looked into it a tad further. I reached out to AGP and received a response that thanked me for my inquiry but refused to confirm or deny whether it was in any sort of professional relationship with Tesla. Ironically, AGP gave the answer we needed, because responding to me was all I needed to know.
Many may ask, “What’s the significance of what glass Tesla is using on its cars?” There are plenty of automotive glass suppliers out there that are worth their weight in gold, providing high-quality windshields and windows for vehicles on the road. Of course, consumers are going to want something that is relatively high quality, because nothing is worse than driving behind a tractor-trailer on the Interstate, just to have a chip or small crack on your windshield from something as tiny as a pebble. While strength is undoubtedly a need for all windshields, EVs require a slightly different bit of development.
One of the biggest focuses for EVs is their drag coefficient. Why is it so important? Because aerodynamics are crucial to the performance, range, and effectiveness of electric vehicles. As high-quality, long-range batteries are hard to come by in the EV sector, manufacturers look for every advantage they can get to achieve robust range ratings. While Tesla is the leader in EV range figures, the company is still looking for ways to get all of its vehicles to or near the 400-mile threshold.
Aerodynamics are a great way to do that. And Tesla undoubtedly worked extremely hard to achieve the best-in-class drag coefficient of .208, beating out the Lucid Air’s impressive .21 coefficient.
We knew aerodynamics was going to be a big part of the Plaid Model S when it was spotted at the Nürburgring two years ago. The vehicle was sporting a large spoiler, a huge rear diffuser, and the new eGlass from AGP is just another addition to Tesla’s attempts to make the Plaid Model S the most aerodynamic vehicle in its lineup.

We finally confirmed that AGP was providing the highly aerodynamic and EV-specific automotive glass to the Model S Plaid thanks to Tesla Raj, who took a picture of the manufacturer’s sticker on the window of the all-electric sedan at Tesla’s Delivery Event on June 10th. This all confirmed Teslarati’s discovery of AGP in its supplier list several months ago and also confirmed that the two companies had a partnership, despite AGP’s unwillingness to provide a comment (which we understood why!)

It makes me think about what Elon Musk may have needed to work on for the final week of Plaid development. When he had announced that the event was going to be delayed a week due to “tweaks,” I wondered whether it was software or hardware. While it was likely a software fix that needed to be addressed, it could have been related to the drag coefficient, which Tesla proudly displayed at the Plaid Event on the 10th. Nevertheless, the vehicle has finally been released to pre-orderers, and the fastest production car that has ever run the 1/4-mile drag is here, and it’s taking down anything in its path.
A big thanks to our long-time supporters and new subscribers! Thank you.

Tesla’s two defunct flagship models are getting a big upgrade
Tesla’s two recently-defunct flagship models, the Model S and Model X, are getting a big upgrade, according to the company’s Head of AI, Ashok Elluswamy.
Older Hardware 3 Model S and Model X vehicles have been the last major holdouts in Tesla’s Full Self-Driving v14 Lite rollout, and that wait now appears to be ending.
Tesla brings closure to flagship ‘sentimental’ models, Musk confirms
At Tesla’s Cybercab launch, AI chief Ashok Elluswamy told Ryan McCaffrey that he thought the S and X build “was supposed to go out last week.” Evidently, Elluswamy expects the suite to be rolled out to those HW3 Model S and Model X very soon:
For my @Tesla friends – and specifically Model S & X owners with HW3 who are waiting on FSD v14 Lite – I spoke to @aelluswamy at the Cybercab launch, & when I asked for an ETA on v14 Lite for S/X owners, he said, “Oh, I thought it was supposed to go out last week.”
So: soon! 🙌

Those cars are not the current Model S and Model X, which already ship with Hardware 4. They are the pre-refresh flagships built around Tesla’s older Autopilot computer, often called HW3 or AI3.
Tesla stopped putting that computer in new vehicles years ago, which is why owners treat these S and X cars as a closed generation. Model 3 and Model Y vehicles on the same computer began receiving v14 Lite in late June 2026 and saw a wider North American expansion in July. South Korea followed as an early international market. The S and X versions of the same software never joined that wave.
v14 Lite is Tesla’s way of squeezing the current v14 driving stack onto hardware that cannot run the full AI 4 model. The company describes the process as distillation: behaviors learned on the newer computer, including reinforcement learning and offline models, are compressed so the older chip and cameras can use them as a guide.
Early descriptions put the distilled network at roughly 15 percent of the original size. The result is still supervised Level 2 driving. Tesla has been clear that HW3 cannot support unsupervised Full Self-Driving or robotaxi operation because of memory and bandwidth limits.
The feature list is what made the wait so frustrating for S and X owners, as plenty of new features are to be shipped with it.
Official notes for the first Lite build, firmware 2026.20.5.1, added parking, unparking, and reversing; arrival options for a parking lot, street, driveway, or curbside; speed profiles that stay available at all times; and start-from-park engagement. Tesla also claimed better handling of merges, forks, pedestrians, traffic lights, and cut-ins, plus fewer false slowdowns and smoother lane centering.
A mid-July follow-on build, 2026.20.6.10, added more of the Hardware 4 interface, including a standalone Self-Driving app and the ability to start a trip from Park without a brake-pedal confirmation.
Elluswamy called that version the one “likely going to wide release.”
That wide release already reached most other HW3 cars in the United States and Canada. International timing still depends on regional validation and regulatory approval. For S and X owners, the remaining work appears to be model-specific validation rather than a new software stack.
There is no official Tesla changelog or build number for those two models yet, only Elluswamy’s offhand timeline. Some HW3 drivers who already have Lite report large gains over v12.6; others have described new indecision or phantom braking. The next test will be whether the same software lands cleanly on the older flagships that have waited the longest.
Cybertruck
This tiny Tesla Cybertruck adjustment has big advantages
Yesterday, we reported on Tesla Cybertruck getting some major adjustments from a manufacturing standpoint in an effort to make the all-electric pickup more cost-effective, more reliable, more serviceable, and more easily produced.
Tesla Cybertruck engineer reveals new changes in ‘constantly evolving’ pickup
One of those changes was the addition of a self-reinforcing polypropylene aero shield that sits underneath the truck. Previously, Tesla utilized aluminum for this, but the self-reinforcing polypropylene was more durable while also being cheaper and lighter.
Tesla has revealed another small change it made to the Cybertruck, and it has to do with the side repeater cameras.
Tesla does not wait for a new model year to improve its vehicles. On September 8, Cybertruck lead engineer Wes Morrill posted side-by-side photos of an updated side repeater camera housing now rolling off the line at Gigafactory Texas.
The triangular camera pod mounted on the front fender looks almost identical at first glance. A closer look reveals a revised contour that uses the air already flowing around the truck to keep the lens clearer in rain and road spray.
The side repeater camera was updated – the version on the left is the newer part which uses passive geometry to create airflow disturbance that better keep water off the lens while driving. No cost penalty, just pure vision improvement. pic.twitter.com/wAbXtcL1Jf

The side repeater cameras sit in an exposed position on the Cybertruck’s angular stainless-steel body.
In wet weather, they readily collect water droplets that can degrade the image Autopilot and Full Self-Driving use for lane changes and blind-spot monitoring. Early production trucks sometimes left owners wiping lenses by hand or accepting temporary restrictions on driver-assistance features.
Tesla has added washers to cameras on certain other models and on Cybercab prototypes, but those active systems add cost, complexity, and extra potential leak points.
The new housing solves the problem with passive geometry. Subtle changes in the surround create localized airflow disturbances as the vehicle moves. Those eddies physically push water droplets away from the optical surface. Morrill called the result “pure vision improvement” achieved at “no cost penalty.” Once the production mold is updated, every subsequent part costs the same as the original.
The advantages compound quickly. Clearer cameras in rain improve the reliability of driver-assistance features precisely when they are needed most. The design consumes no extra energy and introduces no new failure modes.
New Cybertrucks built after the tooling changeover receive the updated part automatically. Some owners of trucks delivered as late as June 2026 have already confirmed they received the revised housing. Retrofit questions have appeared in replies, and the cameras appear electrically compatible, though Tesla has not announced an official service program.
A few millimeters of reshaped housing will not make headlines the way a new battery pack does, but these changes are incremental and increase the Cybertruck’s effectiveness as a vehicle over time.
This improvement illustrates how Tesla continues to refine the Cybertruck after volume production began. Better wet-weather vision, zero added cost, and no extra hardware add up to a meaningful gain in everyday usability and safety.

Tesla is rolling out a new FSD version with a massive safety addition
Tesla is rolling out a new version of its Full Self-Driving suite to some owners that comes with the massive addition of a safety feature.
Tesla is rolling out Automatic Collision Evasion with the 2026.27.6 Software Update, which started rolling out to some vehicles last night. We received the update, along with Full Self-Driving v14.3.9, as well as v14.2 Lite, which has identical release notes as the previous version and seems to have some refinements and improvements in behavior and performance.

However, most of the attention has fallen on the Automatic Collision Evasion feature, which we covered in an article last week.
The function will activate Full Self-Driving to “try to keep your vehicle safe and then continue driving. It can engage in the following situations while you are driving manually:
- Scenario 1: A frontal collision is imminent and braking alone may not avoid it.
- Scenario 2: Your vehicle detects that you are not sufficiently attentive to the road (for example, reaching toward the back seat), or that Full Self-Driving (Supervised) may have been unintentionally disengaged.”
Essentially, FSD will take over when the vehicle determines you are not paying sufficient attention or are heading toward a potential collision. The addition of this feature is incredibly useful as distracted driving is a major issue in today’s world.
Along with the new safety feature is Tesla FSD v14.3.9, which has no additional release notes compared to the previous version, but in my first drives, my first impression is that operation is great, and parking is still sort of a pain point.
Just took a 15-mile round trip to the gym and back
Pretty on par with what FSD is nowadays – really good. Not enough time to see what’s good and what’s bad, but these first rides on any version feel shockingly good. They’re all pretty identical https://t.co/WN1qTg4bhE

Additionally, Tesla v14.2. Lite has arrived. A great review of that is available here:

The addition of an Automatic Collision Evasion feature is similar to that of other collision avoidance systems that are used by companies like Hyundai, Kia, and Genesis. These programs typically utilize radar and camera sensors to apply emergency brakes autonomously, though evasive steering in a manual driving mode is pioneered primarily by Tesla’s newest addition.
