Tesla’s battery strategy will be key to Cybertruck and Semi’s market disruption
Elon Musk has remarked that Tesla has arguably the most exciting product roadmap of any company today. With vehicles like the Semi and the Cybertruck coming in the pipeline, this statement rings true. But things will not be as easy as simply setting up production lines for the upcoming vehicles. For Tesla to properly ramp the Semi, for example, the company would have to make sure that it can get enough cells for the vehicle first.
Producing electric cars is no easy task, and a lot of the challenges in EV making are connected in one way or another to vehicles’ batteries. This is something that is being learned by veteran carmakers like Jaguar today, as inadequate supply from battery companies like LG Chem has resulted in a halt of production for premium EVs like the I-PACE. Tesla is certainly aware of the battery supply challenges that EV makers face. This is one of the reasons why Gigafactory Nevada was constructed.
Giga Nevada was built to support the company’s Model 3 ramp. Designed to manufacture the 2170 cells of the Model 3 with battery partner Panasonic, the massive facility forms the backbone of Tesla’s first foray into the mass market. But the story lies far beyond the Model 3 today. Tesla has an even higher-volume vehicle coming, the Model Y. The Cybertruck will likely sell in large volumes too, provided that the market embraces it. Just like the all-electric pickup, the Semi might see sufficient demand from the trucking market once it’s released as well, considering the cost benefits that the vehicle offers.
Tesla is in a constant state of change, and this cannot be represented better than the company’s batteries. President of Automotive Jerome Guillen has noted that Tesla’s batteries are never static since they’re always being improved. Today, it is becoming more and more evident that Tesla’s batteries are among the best in the industry, particularly when it comes to energy density. Coupled with its vertically-integrated software, Tesla’s batteries can give vehicles impressive range even if they are not too large.
The Model 3, for example, can squeeze out over 320 miles of range from a 75 kWh battery, and the Model S Long Range Plus can get 390 miles from a 100 kWh pack. This matters a lot, and it shows just how far ahead the company is when it comes to its batteries and their energy density. And this, ultimately, will likely help the company secure enough battery cells to support the ramp of its upcoming EVs, including the Semi and the Cybertruck, both of which are large vehicles that would usually require a massive pack to hit their target range.
Tesla lists the Semi with a range of 300 to 500 miles. The company never announced the size of the Semi’s battery pack, but considering that the vehicle is a Class 8 truck that can accelerate from 0-60 mph in 20 seconds with a full load, speculations for the vehicle’s battery from the EV community included estimates that were as high as 1 MWh. The same concept applies to the Cybertruck. The vehicle is very heavy, and it is expected to have over 500 miles of range. To get this range, a large battery pack would usually be required.
But with Tesla’s constant innovations on its batteries, this does not necessarily have to be the case. Considering that Tesla is closing in on 400 miles per charge on a 100 kWh pack with the Model S, there is a good chance that its next vehicles like the Cybertruck and Semi will be equipped with fewer, but more energy-dense cells than initially expected. Tesla has pretty much developed the skill of drawing out as much range as possible from every cell in an EV, so it’s not too farfetched to infer that the company will be very efficient with the batteries of its upcoming vehicles.
More energy-dense batteries will be key to lowering production costs as well. Tesla may be drastically reducing its battery costs, but the packs themselves still comprise a huge portion of each of its vehicles’ prices. If Tesla can use slightly smaller packs that are still capable of providing optimum range, Tesla can make sure that its EVs like the Semi and the Cybertruck will be as competitive as possible when they enter the market.
The Tesla Semi and the Cybertruck are competing in the trucking and pickup market, two very lucrative segments in the automotive industry. Interestingly, both segments are also ripe for disruption, with most veterans such as Freightliner and the Ford F-150 sticking to tried and tested strategies to thrive today. Tesla needs a key to ensure that it can have a fighting chance when it enters the trucking and pickup segment with the Semi and Cybertruck. If challenges faced by electric car makers today are any indication, it appears that batteries and their energy density will be the difference-maker. Fortunately, these just happen to be two things that Tesla has been obsessively pursuing since the company was founded less than 17 years ago.
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 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.

Tesla primes Cybercabs for 4K streaming and high bandwidth gaming with Starlink integration
Tesla is now shipping Cybercabs from Giga Texas with Starlink hardware built in as standard.
Tesla’s Cybercabs are now leaving Gigafactory Texas with Starlink hardware on the rear hatch in significant numbers, according to drone footage captured Tuesday by longtime Austin drone observer Joe Tegtmeyer. Production at the factory ramped back up after the Labor Day weekend, and his flyover of the outbound lot showed rows of gold Cybercabs alongside Model Y Long Wheelbase units, many carrying the satellite module for the first time as standard equipment rather than a one off retrofit.
Giga Texas today is busy with production coming back up following the long weekend. Of interest today in the outbound lot is the appearance of hundreds of Mode; YL’s and many more Cybercabs and for the 1st time equipped with the Starlink module one the hatch in big numbers.

Tesla first showed Starlink built into an actual Cybercab on August 10, when the Robotaxi account posted images of a single gold unit with the antenna integrated into the roofline above the taillights and called it the first Cybercab with Starlink integration. That followed a July reveal where Tesla and Starlink jointly posted a cutaway diagram of the antenna placement without a working vehicle to back it up. Ashok Elluswamy, Tesla’s VP of AI software, said at the time that the connection isn’t required for the car to drive itself. It exists mainly for navigation, customer service and keeping tabs on the fleet.
Musk has made a different case in public. During Tesla’s Q2 earnings call, he said the company can’t afford robotaxis stranded in what he called “Bermuda Triangles of lack of cellular connectivity,” and he separately claimed on X that Starlink will eventually reach every Tesla built, calling it the only way to deliver high bandwidth to billions of vehicles. He has also pitched the antenna as an entertainment upgrade, telling riders they would be able to stream 4K video or play games during a trip.
The rollout has moved fast since. Robotaxi service opened to the public in Austin on September 3, and Cybercabs had already been spotted with Starlink hardware in Houston and near Miami International Airport in the weeks before Tuesday’s factory footage showed the module shipping at volume rather than on scattered test units. Whether the satellite link earns its keep is still an open question. Tesla’s unsupervised service currently runs in dense metro geofences in Texas and Florida, markets where cellular coverage is already strong, which is not where the rural dead zones Musk describes tend to show up.
