Tesla releases a major update about once a month that includes feature improvements, safety enhancements or new features.

While some owners may receive an update within a few days of it being released, most owners will actually not receive the latest update for several weeks.

There are a couple of reasons why Tesla doesn't update all of its vehicles at the same time.

Unfortunately, updates for Teslas aren’t like mobile devices where an update is available for everyone right away. There’s a little more that goes into pushing updates for vehicles, especially for a vehicle that can drive itself.

How Tesla Rolls Out Updates

Tesla rolls out updates to its fleet based on the vehicle's VIN, region, model, hardware, and other factors. The main reason Tesla rolls out updates in this manner is to minimize risk and to assess how an update is performing.

Rolling out updates slowly lets Tesla quickly iterate on their update and focus on feedback and bug fixes before a potential issue has the chance to affect a large number of vehicles.

If, for example, an update caused the MCU reboot , making the display go dark while the vehicle was in motion, Tesla could more easily isolate the issue. Tesla would then be able to roll out a fix before the issue had a chance to affect a larger portion of their fleet.

Your vehicle model or other hardware in your vehicle is taken into account as well. For example, if Tesla is looking to gather feedback on a feature that requires MCU 2 or MCU 3, they may first send the update to those vehicles before releasing it more widely.

If you look at our software updates page you'll see that there are Tesla vehicles on a wide variety of updates. Some may be on the same major update, but on a different revision, while others may be one or two major updates 'behind'.

Although a vehicle can have an update that gets 'stuck' while downloading, that's usually relatively rare. If you notice that your vehicle falls too far behind, you can send a message to Tesla Service to see whether there is an issue with your vehicle.

What do the Numbers in Tesla Updates Mean?

Tesla's release process is why you may notice several versions for the same update.

For example, Tesla may first release update 2022.36, but as new issues are found and Tesla fixes them, Tesla will roll out further updates such as 2022.36.1 and 2022.36.2.

The 2022 in the version number stands for the year in which development began for this update. The 36 stands for the week number, and the last number stands for the revision of the update.

So in general, 2022.36.1 would include the same features as update 2022.36 but would contain several fixes for issues that were found in 2022.36, while 2022.36.2 would contain fixes that were fixed after 2022.36.1 was released.

This isn't always the case since Tesla does sometimes release new features with a minor revision, or but in general it's a good rule of thumb.

Once Tesla is confident they have solved all known issues, they'll then send out the update to the entire Tesla fleet.

Can I Force My Vehicle to Receive an Update?

Unfortunately, no. Under normal circumstances, there is no way to force your Tesla to receive an update. You'll simply have to wait until the update is available for your vehicle.

However, there are a couple of things you can do to receive updates as soon as possible.

It's not clear how much this toggle does anymore, but if you're interested in receiving updates as soon as they're available it's a good idea to toggle on “Advanced Updates” under the Software tab in your vehicle.

You'll also want to make sure your car is connected to Wi-Fi as often as possible, such as at home or work. Tesla prefers to download updates over Wi-Fi so this will ensure you get an update as soon as it's available to you.

You can track which updates are going out to by checking our software updates page.

How to Check if Your Tesla is Running the Latest Update

If an update is available for your Tesla, it will usually show up in your mobile app, although it's not clear how often the mobile app checks for updates. If you suspect an update may be available for your vehicle, you can check in your vehicle, although Tesla has recently started limiting this check to once per 24-hour period.

To check if there is an update available for your Tesla, tap Controls (the car icon), and then tap on Software. On the right side, you'll be able to check your vehicle's version and whether an update is available.

Your vehicle does not need to be connected to Wi-Fi to check whether an update is available

Do I Need to be on Wi-Fi?

For the most part, Tesla requires that updates be downloaded while the vehicle is connected to Wi-Fi.

However, there are exceptions to this. If an update includes important fixes or a recall then it is usually available over cellular. The same goes if you haven’t updated your vehicle in a while, are on FSD Beta, or other unique scenarios.

If you can't connect to Wi-Fi at home or work, you can try using public Wi-Fi networks or using your mobile phone as a hotspot for your vehicle.

Tesla's Project E41: New Model Y With 20% Cost Reduction Coming in 2026

By Karan Singh

According to Chinese blog posts from earlier last week, now vetted by Reuters, Tesla intends to produce a cut-down version of the Model Y, initially for the Chinese market, sometime in 2026.

This follows the launch of Tesla’s cut-down Model 3 for Mexico, as well as news that Tesla intends to launch their new next-gen model sometime in the near future.

Cut Down, But How?

The new Model Y, internally referred to as Project E41, is designed to lower the entry price of Tesla’s popular SUV—one of the most compelling options on the market due to its size, range, and versatility, especially following the launch of the refreshed Model Y.

To achieve this, Tesla is reportedly aiming to reduce the Model Y’s total cost by nearly 20%, according to reports from China. While exact changes remain unknown, we can make informed guesses based on the cost-saving measures Tesla implemented in the scaled-down Model 3 for Mexico.

Textile Seats and Trim

One of the most noticeable changes in the cost-cut version of the Model 3 in Mexico was the removal of vegan leather throughout the interior. In its place, Tesla opted for a durable textile fabric for the seats, reducing material costs. Additionally, any Alcantara trim pieces were replaced with the same textile in various areas.

No Heated or Cooled Seats

Another major cost-cutting measure was the removal of heated and cooled seats, along with the heated steering wheel. While these feature reductions may seem minor, eliminating them reduces various things, such as electrical components, harnesses, and ductwork that are required for seat ventilation.

No Rear Screen

One of the more unexpected changes in the reduced-cost Model 3 was the removal of the rear screen, despite it being powered by the same front infotainment computer as the front display. Given that the screen functions primarily as an additional display rather than a standalone system, the cost to include it is extremely low. It’s one of those really smart additions Tesla has added that increases value for the consumer with minimal cost to Tesla.

Tesla is unlikely to redesign or modify the vehicle’s wiring harness for this change, meaning a rear screen could potentially be retrofitted later by the customer. Based on replacement part estimates, the screen likely costs Tesla between $5 and $20 per vehicle, which acts as a secondary monitor for the infotainment computer.

Ambient Lighting, Acoustic Glass, Speakers

The final set of changes also focuses on the interior. Tesla replaced the RGB-capable ambient lighting with a simpler white-only version—likely saving only a few dollars per vehicle. While this may seem like a minor and somewhat unexpected cut, it could serve as an upsell opportunity to the standard RWD variant.

Additionally, Tesla reduced the use of dual-pane acoustic glass, now limiting it to just the front windows and windshield. This change drastically cuts costs but also affects cabin noise levels. The dual-pane glass played a key role in making the refreshed Model Y noticeably quieter, so this downgrade will likely bring noise insulation closer to that of the original Model Y.

As for audio, Tesla scaled down the speaker system in the Mexican Model 3 from 17 speakers to just nine, while also removing the subwoofers and one of the audio amplifiers. While this cuts costs due to wiring and speakers, it also has a large impact on the audio quality in the vehicle.

Project E41 is Not the Next-Gen Model

It’s important to note that Project E41 is not the same as the upcoming, more affordable next-gen platform, which is internally referred to as Project Redwood. While Project E41 focuses on a reduced-cost version of the Model Y, Project Redwood is designed to test Tesla’s manufacturing capabilities, using their innovative unboxed assembly method to reduce both costs and production time. The goal is to create a vehicle that is smaller and more affordable, while also keeping it safe and capable of self-driving.

Tesla previously confirmed that they plan to unveil new models—distinct from cut-down versions of the Model 3 or Model Y—during their Q4 2024 Earnings Call. However, the executive team has been careful not to divulge too many details about the upcoming model during interviews. This suggests there may be a lot more that has yet to be unveiled.

The Original Design and Inspiration of the Tesla Cybertruck

The Cybertruck is something that’s completely out of this world—so much so that when people are unfamiliar with it, their first reaction is often, “What is that?”

And stepping inside only reinforces that impression. With its hidden-button doors and sleek, futuristic interior, the Cybertruck truly feels like something from another world. Recently, Tesla’s Chief Vehicle Designer, Franz von Holzhausen, revealed that an image shared by the official Cybertruck account on X is actually the original sketch that inspired its radical design.

Many Iterations

The Cybertruck has undergone numerous design iterations, and we’ve had the chance to explore some of Tesla’s earliest concepts for a truck that would define the future in many ways. These insights come from Walter Isaacson, who detailed them in his biography of Elon Musk.

Originally shared in 2023, the images revealed a dramatically different vision—one without the now-iconic angular rear sail. The design drew inspiration from various art forms, including video games, books, and movies—essentially, anywhere sci-fi had imagined a sleek, futuristic, or rugged truck.

The Nighthawk

The design that ultimately made it to production wasn’t one of those early concepts. Instead, it was inspired by none other than the infamous American F-117 Nighthawk—a now-retired, single-seat stealth bomber developed by the secretive Skunk Works for the U.S. military. As the world’s first stealth aircraft, the F-117 revolutionized aviation with its groundbreaking design.

Much like the Cybertruck’s deluge of new technologies, the F-117 brought innovations that reshaped modern aircraft design. Its angular, faceted surfaces were engineered to deflect radar waves and reduce its infrared signature—features that directly influenced the Cybertruck’s distinctive geometry. When wrapped in black, the resemblance to the Nighthawk is undeniable.

Now, while we can’t say for sure if the Cybertruck is truly “stealthy”—since it turns heads wherever it goes—it does reflect radar waves. That said, don’t expect it to help you evade speed cameras or slip past the police unnoticed.

The Nighthawk’s angular design also required advanced computerization—because, at first, no one believed it could even fly. Without its onboard computers to fine-tune the pilot’s inputs, it simply wouldn’t have. Similarly, the Cybertruck’s steer-by-wire system and rear-wheel steering give it an unexpected level of agility—especially for a massive stainless-steel vehicle that’s this fast.

The Cybertruck is truly one of a kind—there’s nothing else like it on the road today. Franz von Holzhausen delivered on Elon Musk’s vision of a truck from the future, and Tesla’s engineering team brought that vision to life in a way that few thought possible.
