Like 90% of trucks and SUVs, most Cybertruck will never leave the pavement. But Tesla is setting the stage for a significant upgrade that promises to elevate its off-road performance for the small group of owners that may actually get the Cybertruck a little dirty. The feature will be in an upcoming software update, confirmed by the lead Tesla Cybertruck engineer.

Upcoming Update

Traditionally, the acquisition of a vehicle came with a fixed set of features, with any upgrades necessitating physical modifications or replacements. However, Tesla has redefined this paradigm by implementing software-defined vehicles.

Yes, we have dual and tri and testing out both the mechanical lockers as well as E-Locker for Tri rear. Coming via OTA soon

Tesla's Cybertruck is undergoing rigorous testing to perfect the integration of locking differentials. Wes Morrill, Cybertruck Lead Engineer, revealed that the team is experimenting with both mechanical and electronic locking systems for the rear axles and will enable them in an upcoming software update. The fact that Tesla is already testing the feature in the Cybertruck means that it could be released imminently. at least if testing goes well.

The Mechanics of Locking Differentials

In vehicles, a differential allows wheels on an axle to rotate at different speeds, which is crucial for turning. However, in off-road scenarios, this can lead to a wheel spinning freely if it loses traction, limiting forward movement. Locking differentials solve this by forcing both wheels on an axle to move at the same speed, ensuring that power is efficiently directed to the wheel with better grip, enhancing off-road capability.

The driver can engage Locking differentials manually or automatically, adapting to changes in traction on the fly. Tesla's Cybertruck is poised to feature electronic locking differentials, utilizing electromagnets or solenoids controlled by the vehicle's software. This enables precise, dynamic adjustment to driving conditions, ensuring optimal traction across diverse terrains.

This technology represents a significant advancement in vehicle design, merging mechanical robustness with digital intelligence. By automatically detecting and responding to traction needs, the Cybertruck's locking differentials will offer drivers a superior off-road experience, showcasing the potential of integrating software solutions with traditional automotive mechanisms for improved performance.

Tesla Vehicles Spotted With LiDAR: What Do They Use It For?

Tesla recently hit the news for purchasing approximately $2M in LiDAR sensors from Luminar, one of Tesla’s long-term suppliers. You’ve probably seen photos of Tesla’s Semi and various Tesla models, including the Model 3 and Model Y sporting LIDAR equipment on the roof. These cars drive around with manufacturer plates scanning streets and highways.

However, many people confuse Tesla’s purpose in purchasing LiDAR equipment with using it for FSD versus testing. So, let’s look at what LiDAR is, and why Tesla uses it on its Fleet Validation Vehicles.

What is LiDAR?

LiDAR stands for Light Detecting and Ranging – essentially using lasers to measure distances. A laser pulse is sent out, and the time it takes to return is measured – providing extremely accurate distance measurements.

Some companies working on self-driving vehicles, including Waymo and BYD, use LiDAR as part of their self-driving suites, but Tesla is one of the few stand-outs that does not. Even Rimac’s “Verne” Robotaxi – which uses self-driving technology from Mobileye, also uses LiDAR.

While LiDAR can produce extremely accurate and high-quality 3D environments, it comes with its downsides as well. Not only is LiDAR costly and requires large gear strapped to a vehicle, but it also can not be used in bad weather and can have interference issues if there are other strong light sources present.

Why Does Tesla Use LiDAR?

At Autonomy Day in 2019, Elon Musk mentioned that LiDAR isn’t the solution for self-driving cars – it's just a crutch. Thus, Tesla hasn’t used LiDAR for any production self-driving software.

Instead, Tesla uses it exactly how it's described – they use it to gather ground-truth data. This data is then used to feed Tesla’s Full Self Driving system – which helps validate its vision-only system's accuracy. LiDAR provides very accurate measurements to help ensure that FSD’s perception of space is accurate – and is only used by Tesla to ensure that its AI technology which is the brains of FSD is capable of accurately interpreting depth from just visual data.

Tesla’s vision-only system has been seen to be extremely accurate, with Vision-only Autopark being able to park in even narrower and tighter spaces faster than the previous version that relied on ultrasonic sensors.

We’ll likely continue to see Tesla purchase LiDAR systems, as well as use them for validation well into the future.

Tesla's Upcoming Robotaxi Event in August Delayed, According to Bloomberg

In a report from Bloomberg, it is claimed that Tesla will be delaying its much-anticipated 8/8 Robotaxi event by two months to October 2024.

While sources other than Bloomberg haven't confirmed this report, Bloomberg has a positive track record of reporting on financial decisions. We’ll be sure to update the article if there is confirmation on X from Elon Musk or another Tesla senior official.

Tesla’s stock has dropped nearly 8.5% over the day, ending back-to-back gains over the last two weeks. It closed yesterday at $ 241 after hitting a peak of $270 earlier in the day before the news broke.

Why the Delay?

The delay – of approximately two months – has been communicated internally, but not publicly announced just yet. Bloomberg goes on to mention that the design team was told to rework certain elements of the Cybercab, necessitating the delay.

If Bloomberg’s report is correct, it sounds like Tesla’s unveil event will be largely focused on showing off the vehicle, instead of demoing how it will work. Of course, it could still be both, but given past events, Tesla has always shown off the vehicle years before it hits production.

Rimac recently showed off their version of robotaxi vehicle named Verne, and surprisingly, it could almost pass for Tesla’s own robotaxi. A lot of design cues in Rimac’s version are elements we have already seen or expect to see in Tesla’s autonomous taxi.

A recent Tesla patent revealed that Tesla is incorporating a sanitation system into their robotaxi that will be responsible for analyzing and cleaning the vehicle’s interior, although the delay itself is likely tied more to a physical feature rather than software.

Another element we know almost nothing about is how Tesla plans to charge these robotic taxis. Will they rely on the existing charge port and adapt a solution like the robotic charging arm (video below) we saw almost eight years ago, or will wireless charging or a dock finally become realized?

While the delay for Tesla’s event appears to be related to the vehicle’s design itself and not further development of FSD, Tesla is wasting no time in getting FSD working for the upcoming vehicle. Model 3 vehicles have already been spotted with camera locations that resemble a robotaxi.

Is the Delay Accurate?

We expect that this delay might actually be true – Elon Musk usually takes to X within hours of such news breaking if it's false to refute it and hasn’t done so yet.

Tesla has delayed several of their events in the past, and a delay of a couple of months seems plausible. We should hear from Musk himself soon on whether this report is accurate.
