In a few late-night tweets, SpaceX CEO Elon Musk offered a rare view inside the company’s Boca Chica Starship fabrication building and revealed that technicians had already installed all three Raptor engines on Starship Mk1.

SpaceX is in the midst of a frenetic few weeks of activity as technicians and engineers – some likely flown in from Florida – work around the clock to ready Starship Mk1 for its first flight tests. Musk is also scheduled to present an official update on Starship’s latest design on September 28th and likely wants to have a complete Starship (or nearly so) as an imposing backdrop for the media event.

The news that SpaceX has already installed all three Raptor engines on Starship Mk1 comes as a surprise, an exceedingly rare instance thanks to near-continuous coverage provided by several local residents and 24/7 livestreams. On September 22nd, at least one Raptor engine was spotted arriving in Boca Chica, but no onlookers noticed engine installation operations.

Capable of producing 600+ metric tons (1.3M lbf) of thrust, those three Raptors were attached to a custom-fabricated thrust structure that was installed inside Starship Mk1 on August 14th, barely a month ago. There’s a chance that one or several of the Raptors installed are nonfunctional spares, but it’s likely that the engines installed are ready for flight and have completed static fires in McGregor, Texas. As such, they could very well be the engines that will power Starship’s inaugural flight tests, the first of which will involve a suborbital launch to an altitude of more than 20 km (12.5 mi).

Musk says that Starship Mk1’s three segments could be stacked atop each other as early as Wednesday, September 25th, also implying that the spacecraft prototype’s nose section should be fully outfitted with batteries, header tanks (small propellant tanks), its own actuating fins, and more in the next 2-3 days.

Additionally, Musk published a brief video inside SpaceX’s recently-completed Boca Chica Starship fabrication building, the only semi-permanent building the company has built at its South Texas facilities. Featuring an abstract series of mirror-like steel panels that created a bit of a house-of-mirrors effect, Musk says the items pictured will be combined to form Starship Mk1 wing hinges and raceways, an external tunnel used for plumbing and cable routing.

SpaceX installed both of Starship Mk1’s aft wings/flaps over a 48 hour period, wrapping up the basic mechanical integration on September 22nd. Work has started on the prototype’s raceway and the frames of the first two wing hinge covers were spotted on Friday. As of midnight local time on September 23rd, SpaceX technicians were welding propellant feed lines to the outside of Starship’s tank section and installing the rocket’s header tanks – small secondary propellant tanks – inside its pointed nose section.

Tesla China was able to sell 71,599 vehicles wholesale in June 2025, reversing eight consecutive months of year-over-year declines. The figure marks a 0.83% increase from the 71,599 vehicles sold wholesale in June 2024 and a 16.1% jump compared to the 61,662 vehicles sold wholesale in May. 

Tesla China’s June numbers were released by the China Passenger Car Association (CPCA) on Tuesday.

Tesla China’s June results in focus

Tesla produces both the Model 3 and Model Y at its Shanghai Gigafactory, which serves as the company’s primary vehicle export hub. Earlier this year, Tesla initiated a changeover for its best-selling vehicle, the Model Y, resulting in a drop in vehicle sales during the first and second quarters.

Tesla’s second-quarter China sales totaled 191,720 units including exports. While these numbers represent a 6.8% year-over-year decline for Tesla China, Q2 did show sequential improvement, rising about 11% from Q1 2025, as noted in a CNEV Post report.

For the first half of the year, Tesla sold 364,474 vehicles wholesale. This represents a 14.6% drop compared to the 426,623 units sold wholesale in the first half of 2024.

China’s competitive local EV market

Tesla’s position in China is notable, especially as the new Model Y is gaining ground in the country’s BEV segment. That being said, Tesla is also facing competition from impressive local brands such as Xiaomi, whose new YU7 electric SUV is larger and more affordable than the Model Y. 

The momentum of the YU7 is impressive, as the vehicle was able to secure 200,000 firm orders within three minutes and over 240,000 locked-in orders within 18 hours. Xiaomi’s previous model, the SU7 electric sedan, which is aimed at the Model, also remains popular, with June deliveries surpassing 25,000 units for the ninth straight month.

While China’s EV market is getting more competitive, Tesla’s new Model Y is also ramping its production and deliveries. Needless to say, Tesla China’s results for the remaining two quarters of 2025 will be very interesting.

Tesla reveals it is using AI to make factories more sustainable: here’s how

Tesla is using AI in its Gigafactory Nevada factory to improve HVAC efficiency.

Tesla has revealed in its Extended Impact Report for 2024 that it is using Artificial Intelligence (AI) to enable its factories to be more sustainable. One example it used was its achievement of managing “the majority of the HVAC infrastructure at Gigafactory Nevada is now AI-controlled” last year.

In a commitment to becoming more efficient and making its production as eco-friendly as possible, Tesla has been working for years to find solutions to reduce energy consumption in its factories.

For example, in 2023, Tesla implemented optimization controls in the plastics and paint shops located at Gigafactory Texas, which increased the efficiency of natural gas consumption. Tesla plans to phase out natural gas use across its factories eventually, but for now, it prioritizes work to reduce emissions from that energy source specifically.

It also uses Hygrometric Control Logic for Air Handling Units at Giafactory Berlin, resulting in 17,000 MWh in energy savings each year. At Gigafactory Nevada, Tesla saves 9.5 GWh of energy through the use of N-Methylpyrrolidone refineries when extracting critical raw material.

Perhaps the most interesting way Tesla is conserving energy is through the use of AI at Gigafactory Nevada, as it describes its use of AI to reduce energy demand:

“In 2023, AI Control for HVAC was expanded from Nevada and Texas to now include our Berlin-Brandenburg and Fremont factories. AI Control policy enables HVAC systems within each factory to work together to process sensor data, model factory dynamics, and apply control actions that safely minimize the energy required to support production. In 2024, this system achieved two milestones: the majority of HVAC infrastructure at Gigafactory Nevada is now AI-controlled, reducing fan and thermal energy demand; and the AI algorithm was extended to manage entire chiller plants, creating a closed-loop control system that optimizes both chilled water consumption and the energy required for its generation, all while maintaining factory conditions.”

Tesla utilizes AI Control “primarily on systems that heat or cool critical factory production spaces and equipment.” AI Control communicates with the preexisting standard control logic of each system, and any issues can be resolved by quickly reverting back to standard control. There were none in 2024.

Tesla says that it is utilizing AI to drive impact at its factories, and it has proven to be a valuable tool in reducing energy consumption at one of its facilities.

Tesla analysts believe Musk and Trump feud will pass

Tesla CEO Elon Musk and U.S. President Donald Trump’s feud shall pass, several bulls say.

Tesla analysts are breaking down the current feud between CEO Elon Musk and U.S. President Donald Trump, as the two continue to disagree on the “Big Beautiful Bill” and its impact on the country’s national debt.

Musk, who headed the Department of Government Efficiency (DOGE) under the Trump Administration, left his post in May. Soon thereafter, he and President Trump entered a very public and verbal disagreement, where things turned sour. They reconciled to an extent, and things seemed to be in the past.

However, the second disagreement between the two started on Monday, as Musk continued to push back on the “Big Beautiful Bill” that the Trump administration is attempting to sign into law. It would, by Musk’s estimation, increase spending and reverse the work DOGE did to trim the deficit.

President Trump has hinted that DOGE could be “the monster” that “eats Elon,” threatening to end the subsidies that SpaceX and Tesla receive. Musk has not been opposed to ending government subsidies for companies, including his own, as long as they are all abolished.

How Tesla could benefit from the ‘Big Beautiful Bill’ that axes EV subsidies

Despite this contentious back-and-forth between the two, analysts are sharing their opinions now, and a few of the more bullish Tesla observers are convinced that this feud will pass, Trump and Musk will resolve their differences as they have before, and things will return to normal.

ARK Invest’s Cathie Wood said this morning that the feud between Musk and Trump is another example of “this too shall pass:”

Additionally, Wedbush’s Dan Ives, in a note to investors this morning, said that the situation “will settle:”

“We believe this situation will settle and at the end of the day Musk needs Trump and Trump needs Musk given the AI Arms Race going on between the US and China. The jabs between Musk and Trump will continue as the Budget rolls through Congress but Tesla investors want Musk to focus on driving Tesla and stop this political angle…which has turned into a life of its own in a roller coaster ride since the November elections.”

Tesla shares are down about 5 percent at 3:10 p.m. on the East Coast.
