Tesla switches Standard Range vehicles to LFP battery chemistry
Among the most interesting announcements made by Tesla during its Q3 2021 Earnings Call yesterday was the strategy to move all of its Standard Range vehicles to a cheaper LFP, or lithium iron phosphate, battery chemistry.
“For standard range vehicles, we are shifting to Lithium Iron Phosphate (LFP) battery chemistry globally,” Tesla said in its Q3 Shareholder’s Deck, released just before the Earnings Call commenced last evening.
It’s a strategy that Tesla adopted in the Chinese market since it has built the Model 3 in Shanghai in early 2020. However, now Tesla is planning to shift the Model 3 Standard Range and Model Y Standard Range vehicles to the LFP pack, which is definitely more available than the standard NCA or nickel cobalt aluminum packs. Tesla actually shifted to utilizing the LFP pack in some SR+ Model 3s and offered customers the opportunity to utilize that pack so they could take delivery quicker. In late August, Tesla emailed some Model 3 orderers with the message that the battery pack could be changed to the LFP pack, which was in healthy supply.
Tesla emailed those who had the vehicle on order in August, saying:
“We are contacting you about your Model 3 Standard Range Plus, currently estimated for delivery near the end of the year. We’d like to offer you the opportunity to receive your car even sooner. Due to limited supply and strong customer demand, we are introducing the Model 3 Standard Range Plus battery pack, which we already released in Europe and Asia, to North America. This battery has a range of 253 miles (est).”
The strategy could have to do with Tesla’s demand, which has exceeded its production rate. The LFP batteries are less expensive than NCA cells and have longer lifespans. The disadvantage to switching to this pack is lower energy density, meaning less power and less range. LFP batteries are also more prone to be affected by weather, something that can cause lower range ratings and prolific differences in power output.
CEO Elon Musk said that Tesla’s intention with the LFP pack is that the “product experience is roughly equivalent between nickel and iron.” Musk added that he’d “personally opt for iron pack, as it wants to be charged to 100%, whereas nickel prefers ~90%.”
Musk also made comments regarding the LFP packs during the Q2 2021 Earnings Call.
“I think probably there is a long-term shift more in the direction of iron-based lithium-ion cells rather over nickel. I think probably we’ll see a shift — my guess is probably to two-thirds iron, one-third nickel, or something on that order. And this is actually good because there’s plenty of iron in the world. There’s an insane amount of iron. But nickel, there’s much less nickel, and there’s way less cobalt.”
The shift in electrification from so many automakers has caused a shortage in some battery materials, which also could be a strategy for the shift to LFP cells by Tesla. Combating delivery times can be solved by switching to other materials, but Tesla plans to also combat shortages by expanding its manufacturing footprint with two new production facilities in Berlin and Austin, Texas.

Elon Musk’s xAI wins permit for power plant supporting AI data centers
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
Mississippi regulators have approved a permit allowing Elon Musk’s artificial intelligence company xAI to construct a natural gas power plant in Southaven. The facility is expected to support the company’s expanding AI infrastructure tied to its Colossus data center operations near Memphis.
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
According to the report, regulators “voted to approve the permit” of xAI subsidiary MZX Tech LLC to construct a power plant featuring 41 natural gas-burning turbines “after careful consideration of all public comments and community concerns.”
The Mississippi Department of Environmental Quality stated that the permit followed a regulatory review process that included public comments and community input. Jaricus Whitlock, air division chief for the MDEQ, stated that the project met all applicable environmental standards.
“The proposed PSD permit in front of the board today not only meets all state and federal permitting regulations, but goes above and beyond what is required by law. MDEQ and the EPA agree that not a single person around our facilities will be exposed to unhealthy levels of air pollution,” Whitlock stated.
The planned facility will help provide electricity for xAI’s AI computing infrastructure in the Memphis region.
The Southaven project forms part of xAI’s efforts to scale computing capacity for its artificial intelligence systems.
The company currently operates two major data centers in Memphis, known as Colossus 1 and Colossus 2, which provide computing power for xAI’s Grok AI models. xAI is also planning to build another large data center in Southaven called Macrohardrr, which would be located in a warehouse previously used by GXO Logistics.
Large-scale AI training requires substantial computing power and electricity, prompting technology companies to develop dedicated energy infrastructure for their data centers.
SpaceX President Gwynne Shotwell previously stated that xAI plans to develop 1.2 gigawatts of power capacity for its Memphis-area AI supercomputer site as part of the federal government’s Ratepayer Protection Pledge. The commitment was announced during an event with United States President Donald Trump.
“As part of today’s commitment, we will take extensive additional steps to continue to reduce the costs of electricity for our neighbors. xAI will therefore commit to develop 1.2 GW of power as our supercomputer’s primary power source. That will be for every additional data center as well. We will expand what is already the largest global Megapack power installation in the world,” Shotwell said.
“The installation will provide enough backup power to power the city of Memphis, and more than sufficient energy to power the town of Southaven, Mississippi where the data center resides. We will build new substations and invest in electrical infrastructure to provide stability to the area’s grid.”

Tesla China teases Optimus robot’s human-looking next-gen hands
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
A new teaser shared by Tesla’s China team appears to show a pair of unusually human-like hands for Optimus.
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
As could be seen in the teaser image, the new version of Optimus’ hands features proportions and finger structures that look strikingly similar to those of a human hand. Their appearance suggests that they might have dexterity approaching that of a human hand.
If the image reflects a new generation of Optimus’ hands, it could indicate Tesla is continuing to refine one of the most critical components of its humanoid robot.
Hands are widely viewed as one of the most difficult engineering challenges in robotics. For Optimus to perform complex real-world work, from manufacturing tasks to household activities, its hands would need to be the best in the industry.
Elon Musk has repeatedly described Optimus as Tesla’s most important long-term product. In posts on social media platform X, Musk has stated that Optimus could eventually become the first real-world Von Neumann machine.
In theory, a Von Neumann machine is a self-replicating system capable of building copies of itself using available materials. The concept was originally proposed by mathematician John von Neumann in the mid-20th century.
“Optimus will be the first Von Neumann machine, capable of building civilization by itself on any viable planet,” Musk wrote in a post on X.
If Optimus is expected to carry out complex work autonomously in the future, high levels of dexterity will likely be essential. This makes the development of advanced robotic hands a key step towards Musk’s long-term expectations for the product.

Tesla Cybercab ramps Robotaxi public street testing as vehicle enters mass production queue
Recent sightings on public roads and growing fleet activity at Giga Texas signal Tesla’s accelerating push toward the Cybercab’s commercial launch.
Tesla Cybercab is being spotted with increasing frequency both on public roads and across the grounds of Gigafactory Texas, suggesting that the company’s road testing and validation program is ramping meaningfully ahead of mass production.
A total of 25 Cybercab units were recently observed across three separate locations at Giga Texas by drone observer Joe Tegtmeyer — with 14 metallic gold units parked in a tight formation outside the factory exit, nine more at the crash testing facility undergoing structural and safety validations, and two additional units at the west end-of-line area for final checks.
The activity on public roads is just as telling. The Cybercab was spotted testing on public roads for the first time last October, near Tesla’s Engineering Headquarters in Los Altos, California, marking a significant development in the vehicle’s progression toward commercial readiness. As expected at that early stage, a safety driver was present in the seat.
Since then, sightings have only become more frequent. Community observers on X have posted fresh footage of Cybercabs navigating public streets in Silicon Valley, with each new clip adding to a growing body of evidence that Tesla’s validation efforts are well underway. The production backdrop supports the momentum. Tesla’s production line at Giga Texas moved into a higher volume early in March, representing what observers are calling the largest single-day grouping of Cybercabs seen to date.

Tesla ramps Cybercab test manufacturing ahead of mass production
Musk has also stated that Tesla is aiming for at least 2 million Cybercab units per year across more than one factory, with a potential ceiling of 4 million annually.
With testing activity on public roads accelerating and factory output visibly increasing week over week, the coming months at Giga Texas are set to be pivotal in determining how quickly Tesla can bring the Cybercab from validation to volume.
