It appears that Tesla is getting faster with its Hardware 3 retrofits, with recent reports from the electric car community suggesting that the upgrade could now take as short as a few hours. This suggests a notable improvement in the turnaround times for HW3 upgrades, especially since previous anecdotes from Tesla owners indicated that the process could take as long as a few days.
Elon Musk has noted that Hardware 3 retrofits will be available for electric cars equipped with HW2 and HW2.5, and whose owners purchased the company’s Full Self-Driving suite. The CEO has also mentioned in the past that retrofits should not take too long, and that Tesla’s mobile service fleet should be able to accomplish the upgrade without any difficulties.
Initial accounts of Hardware 3 retrofits suggested that this was indeed the case. A Tesla Model X P100D owner who runs the Electric Dreams YouTube channel reported back in December that his HW3 retrofit only took a few hours, thanks to a member of Tesla’s Mobile Service team coming over to his home to perform the upgrade. In the case of the Model X owner, the mobile service technician started the retrofit in the morning and completed the upgrade by night.
As Tesla started ramping its Hardware 3 retrofits, it quickly became evident that not all owners will experience the same convenience as related by the Electric Dreams host. Tesla Model 3 owner and enthusiast Tesla Joy, for example, noted that her vehicle’s upgrade ended up taking over five days. This was highly inconvenient, particularly as it resulted in the Model 3 being stuck in the Service Center during New Year’s.
Similar complaints from fellow Model 3 owners suggested that Joy’s experience was not an isolated case. Fellow Model 3 owner Greg Wester, for one, claimed that his Service Center advised him that his HW3 retrofit will take a whole week to complete because of the “disassembly and troubleshooting” that will be involved. Similar to Joy, Wester was given Uber vouchers due to the absence of loaner vehicles.
More recent reports from Tesla owners suggest that Hardware 3 retrofits are now far quicker and more efficient. Tesla owner-enthusiast Tesla Raj recently shared that his Model 3, which was dropped off at a Service Center at 8:30 am, will be fully upgraded by 3:30 pm on the same day. Other Tesla owners commenting on Raj’s tweet shared similar stories, with some stating that their retrofits were also completed within the same day. Even vehicles that had to be left overnight for the retrofit were ready to get back on the road the following day.
Overall, it appears that Tesla is now at a point where its HW3 retrofit process is getting quicker turnaround times. Recent anecdotes from electric car enthusiast @stillstainless noted that the Tesla Lynnwood WA Service Center was actually able to complete a HW3 upgrade in just 2 hours 20 minutes. During this time, the vehicle’s owner reportedly just opted to wait, instead of acquiring a loaner vehicle.
Elon Musk has suggesting in the past that the HW3 retrofit will be a quick, simple process that could be performed by mobile service technicians without any issue. Based on the most recent reports from the Tesla community, it appears that the electric car maker is getting closer to Elon Musk’s estimates. This bodes well for Tesla’s push into the autonomous driving market, especially since Hardware 3 is an important part of the full self-driving puzzle that the company is trying to solve.

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.
