SpaceX’s first orbital Starship rocket engine is almost ready for testing
CEO Elon Musk says that SpaceX is “about a month away” from testing a rocket engine that will be essential for Starship and its Super Heavy booster to reach their full potential.
Known as Raptor Vacuum, the engine – as its name suggests – is a variant of the base Raptor engine optimized for maximum performance and efficiency in the vacuum of space. Although Starship could technically still function and likely reach orbit with only sea level-optimized Raptors installed, it would likely significantly limit the amount of payload it could carry into Earth orbit and would especially harm the ship’s performance to higher orbits and other planets.
Back in May 2019, Musk revealed that SpaceX had shifted gears again, forgoing a plan to begin orbital Starship flight operations with only sea level Raptors, gradually designing and phasing in RaptorVac engines much further down the road. Instead, SpaceX restarted (relatively) urgent work on the vacuum variant and Musk hinted that it would “aspirationally” be ready to support launches in the near term. A few weeks shy of a year later, Musk says that Raptor Vacuum testing could begin as early as June 2020.
For a variety of reasons, even if based directly off of an existing design, vacuum-optimized engines are typically much more complex than a comparable sea level variant. While efficiency is always relatively important for rocket engine design, it becomes even more paramount when dealing with vacuum rocketry, as the entire point of a dedicated vacuum-optimized engine is to eke as much efficiency as possible out of a launch vehicle’s orbital stage(s).
For example, even from a purely visual perspective, Merlin Vacuum (MVac) is substantially different when compared to the Merlin 1D engine it’s based on. Due to a number of major and largely unknown differences, the engines’ shared components are largely invisible. It’s unclear how similar they are but it’s safe to say that they share at least ~50% commonality. Obviously, the most apparent part of the difference between a vacuum-optimized engine and an atmosphere-optimized engine is the bell nozzle: MVac has a nozzle that is dramatically larger than M1D.
Raptor will be no different, with the sea-level variant featuring a nozzle about 1m (3.2 ft) in diameter, whereas RaptorVac’s bell will have a diameter closer to 2.5m (~8 ft). With SpaceX’s apparent May 2019 pivot back to working on RaptorVac now, the company has been working on a dedicated vacuum variant of the high-performance methane-oxygen engine for at least a full year. Now, perhaps beginning as early as June or July, Musk suggests that the first RaptorVac engine (SN0? SN1?) is almost ready to commence static fire testing.
The nature of that testing is a bit of a mystery. While it will almost certainly occur at SpaceX’s McGregor, Texas test and development facilities, it’s unclear if Raptor Vacuum’s first static fire test campaign will be attempted with the engine’s extended nozzle installed. Back in October 2019, Musk suggested that yes, Raptor Vacuum version 1.0 would have a nozzle small enough to operate at sea level without destroying itself or its test facilities. With Merlin Vacuum engines, SpaceX performs acceptance tests in Texas but only without their nozzle extensions installed. If Musk’s October 2019 comments remain true, that may not be the case for RaptorVac.
Either way, it will be thoroughly interesting to note the differences between RaptorVac and its sea level-optimized predecessor if or when Elon Musk or SpaceX releases photos of their newest engine as it nears its first major tests. Simultaneously, SpaceX is also readying a sea-level Raptor for its inaugural static fire test while attached to a full-scale Starship prototype, while the first test with three Raptor engines installed could be attempted just a few weeks from now.

Tesla Model Y sold out in China for 2025
Customers who wish to get their cars by the end of the year would likely need to get an inventory unit.
It appears that the Model Y has been sold out for 2025 in China. This seems to be true for the four variants of the vehicle that are currently offered in the country.
Tesla China’s order page update
A look at Tesla China’s order page for the Model Y shows a message informing customers that those who wish to guarantee delivery by the end of the year should purchase an inventory unit. This was despite the Model Y RWD and Model Y L showing an estimated delivery timeline of 4-8 weeks, and the Model Y Long Range RWD and Model Y Long Range AWD showing 4-13 weeks.
As per industry watchers, these updates on the Model Y’s order page suggest that Tesla China’s sales capacity for the remainder of 2025 has been sold out. The fact that estimated delivery timeframes for the Model Y Long Range RWD and AWD extend up to 13 weeks also bodes well for demand for the vehicle, especially given strong rivals like the Xiaomi YU7, which undercuts the Model Y in price.
Tesla China’s upcoming big updates
What is quite interesting is that Tesla China is still competing in the country with one hand partly tied behind its back. So far, Tesla has only been able to secure partial approval for its flagship self-driving software, FSD, in China. This has resulted in V14 not being rolled out to the country yet. Despite this, Tesla China’s “Autopilot automatic assisted driving on urban roads,” as the system is called locally, has earned positive reviews from users.
As per Elon Musk during the 2025 Annual Shareholder Meeting, however, Tesla is expecting to secure full approval for FSD in China in early 2026. “We have partial approval in China, and we hopefully will have full approval in China around February or March or so. That’s what they’ve told us,” Musk said.

Tesla Full Self-Driving appears to be heading to Europe soon
For years, Musk has said the process for gaining approval in Europe would take significantly more time than it does in the United States. Back in 2019, he predicted it would take six to twelve months to gain approval for Europe, but it has taken much longer.
Tesla Full Self-Driving appears to be heading to Europe soon, especially as the company has continued to expand its testing phases across the continent.
It appears that the effort is getting even bigger, as the company recently posted a job for a Vehicle Operator in Prague, Czech Republic.
This would be the third country the company is seeking a Vehicle Operator in for the European market, joining Germany and Hungary, which already have job postings in Berlin, Prüm, and Budapest, respectively.

This position specifically targets the Engineering and Information Technology departments at Tesla, and not the Robotics and Artificial Intelligence job category that relates to Robotaxi job postings.
Although there has been a posting for Robotaxi Operators in the Eastern Hemisphere, more specifically, Israel, this specific posting has to do with data collection, likely to bolster the company’s position in Europe with FSD.
The job description says:
“We are seeking a highly motivated employee to strengthen our team responsible for vehicle data collection. The Driver/Vehicle Operator position is tasked with capturing high-quality data that contributes to improving our vehicles’ performance. This role requires self-initiative, flexibility, attention to detail, and the ability to work in a dynamic environment.”
It also notes the job is for a fixed term of one year.
The position requires operation of a vehicle for data collection within a defined area, and requires the Vehicle Operator to provide feedback to improve data collection processes, analyze and report collected data, and create daily driving reports.
The posting also solidifies the company’s intention to bring its Full Self-Driving platform to Europe in the coming months, something it has worked tirelessly to achieve as it spars with local regulators.
For years, Musk has said the process for gaining approval in Europe would take significantly more time than it does in the United States. Back in 2019, he predicted it would take six to twelve months to gain approval for Europe, but it has taken much longer.
This year, Musk went on to say that the process of getting FSD to move forward has been “very frustrating,” and said it “hurts the safety of the people of Europe.”

Tesla celebrates 75k Superchargers, less than 5 months since 70k-stall milestone
Tesla’s 75,000th stall is hosted at the South Hobart Smart Store on Cascade Road, South Hobart, Tasmania.
Tesla has crossed another major charging milestone by officially installing its 75,000th Supercharger stall worldwide. The electric vehicle maker chose South Hobart, Tasmania, as the commemorative location of its 75,000th Supercharger.
Tesla’s 75,000th Supercharger
Tesla’s 75,000th stall is hosted at the South Hobart Smart Store on Cascade Road, South Hobart, TAS 7004, as noted in a techAU report. The location features four next-generation V4 Superchargers, which are built with longer cables that should make it easy even for non-Teslas to use the rapid charger. The site also includes simplified payment options, aligning with Tesla’s push to make V4 stations more accessible to a broader set of drivers.
For Tasmanian EV owners, the installation fills an important regional gap, improving long-distance coverage around Hobart and strengthening the area’s appeal for mainland travelers traveling by electric vehicle. Similar to other commemorative Superchargers, the 70,000th stall is quite special as it is finished in Glacier Blue paint. Tesla’s 50,000th stall, which is in California, is painted a stunning red, and the 60,000th stall, which is in Japan, features unique origami-inspired graphics.
Accelerating Supercharger milestones
The Tesla Supercharger’s pace of expansion shows no signs of slowing. Tesla celebrated its 70,000th stall at a 12-stall site in Burleson, Texas late June 2025. Just eight months earlier, Tesla announced that it had celebrated the buildout of its 60,000th Supercharger, which was built in Enshu Morimachi, Shizuoka Prefecture, Japan.
Tesla’s Supercharger Network also recently received accolades in the United Kingdom, with the 2025 Zapmap survey naming the rapid charging system as the Best Large EV Charging Network for the second year in a row. Survey respondents praised the Supercharger Network for its ease of use, price, and reliability, which is best-in-class. The fact that the network has also been opened for non-Teslas is just icing on the cake.
