SpaceX CEO Elon Musk teases white-hot Starship heat shield testing in video
SpaceX CEO Elon Musk has shared a video showing what looks to be the early stages of testing for Starship’s (BFS) unprecedented metallic heat shield, recently described as a double-layered steel sandwich that will be regeneratively cooled by cryogenic liquid methane.

The glowing metal coupon pictured in Musk’s video appears to be heated by the same high-temperature torches SpaceX (and contractors) use to spin-form Falcon 9 and Heavy propellant tank domes and Merlin 1D and MVac engines, potentially explaining the reported 1100C (2000F) the metallic (steel, presumably) heat shield was being heated to. Compared to the temperature range (~1200-1500C) Starship is expected to experience during reentries, 1100C should – according to Musk – be low enough that “no heat shield [is] needed”. If the coupon pictured is an actual double-layered, regen-cooled test article for Starship’s active heat shield, it will need to be torture-tested to 1500C (and likely beyond) to really prove its worth and reliability.

This is more likely an example of rough, ad-hoc testing being used to generally characterize and navigate the early stages of new technology development, hence the improvised testbed of a few ceramic insulation blankets and industrial torches already on-hand at SpaceX’s Hawthorne, CA factory. A hypersonic wind tunnel or arc jet setup is preferable if the goal is to prove out a truly cutting-edge heat shield, but facilities that feature those testbeds are extraordinarily rare, have niche use-cases, and are not cheap to build or operate.
SpaceX’s metallurgy team and thermal protection engineers will thus probably end up at such a facility (likely NASA Ames) to extensively test Starship’s regeneratively-cooled steel heat shield, with tests like those shown off by Musk acting to guide early development up to the point that accurately simulating reentry conditions is necessary or valuable.
In the meantime, SpaceX suffered a bit of a setback when those responsible for properly securing the first Starship prototype’s nose section failed to account for the threat of even mild winds in South Texas. As a consequence, a minor windstorm – with gusts no more than 50-60 mph (80-90 km/h) – toppled the extremely large and light nose section, causing it to crumple on the ground and nearly fold in half under its own weight. Much like the Falcon fairings SpaceX is already familiar with, the Starhopper’s nose/fairing was clearly optimized for very specific loads and did not appear to be a particularly sturdy structure as SpaceX technicians gradually stacked and welded its thin sheet metal sections together through December and January.

Elon Musk indicated that the injured nose cone would take several weeks to repair, likely pushing the beginning of Starhopper’s hop test campaign into late-February or March.

Deliveries followed a similar pattern, with 373,728 Model 3/Ys delivered and 10,394 from other models, totaling 384,122.
The quarter’s 9.6 GWh energy storage deployment marks one of Tesla’s highest to date, signaling continued strength in the Megapack and Powerwall segments.
Year-on-year deliveries edge down, but energy shows resilience
Tesla will share its full Q2 2025 earnings results after the market closes on Wednesday, July 23, 2025, with a live earnings call scheduled for 4:30 p.m. CT / 5:30 p.m. ET. The company will publish its quarterly update at ir.tesla.com, followed by a Q&A webcast featuring company leadership. Executives such as CEO Elon Musk are expected to be in attendance.
Tesla investors are expected to inquire about several of the company’s ongoing projects in the upcoming Q2 2025 earnings call. Expected topics include the new Model Y ramp across the United States, China, and Germany, as well as the ramp of FSD in territories outside the US and China. Questions about the company’s Robotaxi business, as well as the long-referenced but yet to be announced affordable models are also expected.

Tesla China breaks 8-month slump by selling 71,599 vehicles wholesale in June
Tesla China’s June numbers were released by the China Passenger Car Association (CPCA) on Tuesday.

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 Tesla Model 3, 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.
