Tesla quietly revealed in its Q1 report that nearly half the vehicles it produced in the first quarter of 2022 were equipped with cobalt-free lithium iron phosphate (LFP) batteries. The news, however, was overshadowed in the news cycle, particularly by Tesla’s $19 billion revenue and CEO Elon Musk’s acquisition of social media platform Twitter. 

LFP batteries are not a new innovation, but it has not been used as much in areas outside China. According to data from Benchmark Mineral Intelligence (BMI), only 3% of electric vehicle batteries in the United States and Canada and 6% in the European Union are iron-based. In China, however, LFP batteries command 44% of the EV market. 

Tesla currently uses LFP batteries in its base vehicles, though Elon Musk has hinted that the EV company will be using more cobalt-free cells in more products. Considering the prolific nature of Tesla and its influence on the market, it would not be surprising if other EV makers also began exploring the option of using LFP batteries for their own cars. 

Amusingly enough, by playing a notable part in LFP battery adoption, it appears that Elon Musk has effectively become an “iron man” of sorts. 

According to a Reuters review of the EV market, Tesla is not alone in its support for LFP batteries. Over a dozen companies are reportedly considering building LFP battery cell plants in the United States and Europe in the next three years. And things will likely only pick up from there. Mujeeb Ijaz, the founder of US battery startup Our Next Energy, noted that LFP has a future in the EV industry. 

“I think lithium iron phosphate has a new life. It has a clear and long-term advantage for the electric vehicle industry,” he said.

There was a reason why LFP batteries took this long to gain ground. While LFP cells use cheaper materials, and while they could be consistently charged fully without much degradation, they tend to be larger, heavier, and generally hold less energy than nickel-cobalt-manganese (NCM) cells. Thus, electric cars that use LFP batteries tend to have shorter range. 

Tesla’s decision to use LFP batteries for its base vehicles could be considered a strategic move. Since the company is electively the undisputed leader in the electric vehicle sector, the roughly 150,000 cars it produced last quarter that were equipped with LFP batteries took a number of analysts and specialists by surprise. And similar to other innovations from the company, such as its use of megacasts, it appears that other carmakers will soon be following suit. 

EV startup Fisker, for one, noted that it is planning on using LFP batteries for its lower-range SUVs. CEO Henrik Fisker noted that the company is in discussions with battery suppliers from the United States, Canada, or Mexico. Fisker noted that LFP batteries are perfect for vehicles that are used by city-dwellers. 

“If I never leave Los Angeles, I never leave San Francisco, I never leave London … I think that’s where LFP comes in really well,” he said. 

Audi CEO Markus Duesmann, in comments that were shared last March, also spoke highly of LFP cells’ potential. “It may well be that we will see LFP in a larger portion of the fleet in the medium term. After the war, a new situation will emerge; we will adapt to that and choose battery technologies and specifications accordingly,” he said. 

Even BMW, which is arguably lagging in the electric vehicle race considering the pace of rivals such as Volkswagen and Daimler, is looking towards LFP batteries. Recent comments from BMW chief procurement officer Joachim Post indicated that the German automaker was analyzing the merits of iron-based cells. “We’re looking at different technologies to minimize the use of resources and also we’re looking at optimizing chemistry,” the executive said.

Tesla’s two defunct flagship models are getting a big upgrade

Published

on

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:

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.

This tiny Tesla Cybertruck adjustment has big advantages

Published

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 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.

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.
