Tesla has now released update 2023.38 to roughly half of its fleet. Now that the update is in the wild, a couple additional enhancements have been spotted that are only available in certain regions.

Predictive Charger Availability

Tesla has continually improved Supercharger information in the vehicle. In the past couple years they've added the ability to view the number of chargers available at site Supercharger location, as well the number of stalls that are out of order. They also show how busy the Supercharger is at various points throughout the day.

If you thought live data was the best Tesla could do, they have a surprise in store in update 2023.38. If you're navigating to a Supercharger, Tesla will now predict how many Supercharger stalls will be available at your arrival, and display the predicted wait time, if any.

Tesla says they will factor in your travel time to the Supercharger, as well as other Tesla vehicles' travel times, to predict the charger's availability when you arrive.

Tesla continues to open up Supercharger to other electric vehicles, and while the number of non-Teslas charging at Superchargers may be a small percentage right now, that number is expected to increase as more manufacturers adopt Tesla's charging port. It'll be interesting to see how well Tesla can predict Supercharger availability when they may not be aware of all vehicles routing to each charger.

This feature is currently limited to the U.S., but is likely to expand to other regions as Tesla gathers more data and determines its accuracy.

Updated Hazard Lights Pattern

We recently talked about Tesla's upcoming update to hazard lights. It looks like Tesla will use the updated light pattern, which flashes up to about three times quicker, if the vehicle is involved in an accident.

When Tesla officially announced the feature on X, it wasn't clear which update the feature would feature the updated feature, but it has now been spotted in update 2023.38. The updated light pattern is currently only be available in select countries, including the U.S. It appears to not be available in most of Europe at this time, but that may change in a future update.

Vampire Survivors: Multiplayer Gaming

Update 2023.38 also brings other features, such as an update to Vampure Survivors. Just in time for Halloween, Tesla owners and their passengers can team up in a co-op mode, mowing down hordes of the undead. The gameplay allows up to four passengers to participate, turning your vehicle into a virtual battleground against zombies. This feature, however, has its prerequisites.

It requires MCU 3, making it exclusive to the recent Model S/X and 3/Y models. For those ready to dive into this electrifying experience, shift the Tesla into Park (P), navigate to the Tesla Arcade, and then choose Vampire Survivors. Remember, each player needs their own controller, which can now be wired or Bluetooth.

Location Sharing: Enhanced Transparency

Update 2023.38 also notifies drivers if they are being crept on, known as location sharing. A new icon now appears at the top of the touchscreen when any app — including the official Tesla app — requests live location data from your vehicle.

This icon will also show up if future third-party services have access to your vehicle's location.

Windows Adjustment

Tesla also introduces a practical modification that could prevent window or door damage during a vehicle update. We know that the window goes down just a little bit when the door opens and closes because of the distinct frameless door design. However, the windows can not adjust during software updates, increasing the chances of window damage. This update brings down the windows just a little bit to facilitate door opening and closing. Once the update concludes, the windows revert to their former position.

With every update, Tesla gets just a little bit better. We are just a few months away from the epic Christmas update. The countdown is on!

A Look at the Tesla Cybertruck’s Crumple Zones [VIDEO]

Tesla’s Cybertruck has officially earned a 5-Star Safety Rating from the NHTSA—an impressive achievement given the vehicle’s design. The achievement demonstrates Tesla’s engineering prowess. As one engineer points out, it wasn’t an easy feat.

Interestingly, the NHTSA only recently disclosed the results, despite the crash tests being completed a while ago. According to Lars Moravy, Tesla’s VP of Vehicle Engineering, the team had been aware of the 5-star rating for quite some time. While the reason for the delay remains unclear, now that the results are public, Tesla’s engineers can finally share how they achieved the rating.

Crumple Zones

Wes Morril, the Cybertruck’s Lead Engineer, wrote about the crash test video on X recently, addressing the claims that the Cybertruck doesn’t have a crumple zone. He also posted a side-by-side video (below) of the engineering analysis and the crash test itself.

Engineered Crash Safety

There’s a lot of engineering precision at play when a Cybertruck is involved in a crash. Unlike traditional crash structures that rely on crash cans and collapse points, the Cybertruck’s front gigacasting is designed to absorb and redirect impact forces in a highly controlled manner.

It all starts with the bumper beam, which crushes within the first few milliseconds of a high-speed impact. At the same time, the vehicle’s sensors rapidly analyze the crash dynamics and determine the optimal deployment of safety restraints, including airbags and seat belt pre-tensioners. These split-second actions are crucial in keeping occupants safe.

As the crash progresses, the vehicle’s structure deforms in a carefully engineered sequence. The drive unit cradle bends, directing the solid drive unit downward and out of the way, allowing the gigacasting to begin absorbing impact forces.

The casting crushes cell by cell, methodically dissipating energy in a controlled manner. This gradual deceleration reduces the g-forces transferred to occupants, making the crash much less severe. As the gigacast begins crushing, the safety restraints are deployed.

As Wes points out in his post - you can see how accurate the virtual analysis and modeling were. The video shows the simulated crash side by side with the real-life crash test and they’re almost identical. All that virtual testing helps provide feedback into the loop to design a better and safer system - one that is uniquely different than any other vehicle on the road.

Tesla Eliminates Front Casting on New Model Y; Improves Rear Casting

Tesla has pioneered the use of single-piece castings for the front and rear sections of their vehicles, thanks to its innovative Gigapress process. Many automakers are now following suit, as this approach allows the crash structure to be integrated directly into the casting.

This makes the castings not only safer but also easier to manufacture in a single step, reducing costs and improving repairability. For example, replacing the entire rear frame of a Cybertruck is estimated to cost under $10,000 USD, with most of the expense coming from labor, according to estimates shared on X after high-speed rear collisions.

These insights come from Sandy Munro’s interview (posted below) with Lars Moravy, Tesla’s VP of Vehicle Engineering, highlighting how these advancements contribute to the improvements in Tesla’s latest vehicles, including the New Model Y.

However, with the new Model Y, Tesla has decided to go a different route and eliminated the front gigacast.

No Front Casting

Tesla’s factories aren’t equipped to produce both front and rear castings for the Model Y. Only Giga Texas and Giga Berlin used structural battery packs, but these were quickly phased out due to the underwhelming performance of the first-generation 4680 battery.

Tesla has gone back to building a common body across the globe, increasing part interchangeability and reducing supply chain complexity across the four factories that produce the Model Y. They’ve instead improved and reduced the number of unique parts up front to help simplify assembly and repair.

There is still potential for Tesla to switch back to using a front and rear casting - especially with their innovative unboxed assembly method. However, that will also require Tesla to begin using a structural battery pack again, which could potentially happen in the future with new battery technology.

Rear Casting Improvements

The rear casting has been completely redesigned, shedding 7 kg (15.4 lbs) and cutting machining time in half. Originally weighing around 67 kg (147 lbs), the new casting is now approximately 60 kg (132 lbs).

This 15% weight reduction improves both vehicle dynamics and range while also increasing the rear structure’s stiffness, reducing body flex during maneuvers.

Tesla leveraged its in-house fluid dynamics software to optimize the design, resulting in castings that resemble organic structures in some areas and flowing river patterns in others. Additionally, manufacturing efficiency has dramatically improved—the casting process, which originally took 180 seconds per part, has been reduced to just 75 seconds, a nearly 60% time reduction per unit.

New Casting Methods

Tesla’s new casting method incorporates conformal cooling, which cools the die directly within the gigapress. Tesla has been refining the die-casting machines and collaborating with manufacturers to improve the gigapress process.

In 2023, Tesla patented a thermal control unit for the casting process. This system uses real-time temperature analysis and precise mixing of metal streams to optimize casting quality. SETI Park, which covers Tesla’s manufacturing patents on X, offers a great series for those interested in learning more.

The new system allows Tesla to control the flow of cooling liquid, precisely directing water to different parts of the die, cooling them at varying rates. This enables faster material flow and quicker cooling, improving both dimensional stability and the speed of removing the part from the press for the next stage.

With these new process improvements, Tesla now rolls out a new Model Y at Giga Berlin, Giga Texas, and Fremont every 43 seconds—an astounding achievement in auto manufacturing. Meanwhile, Giga Shanghai operates two Model Y lines, delivering a completed vehicle every 35 seconds.
