Elon Musk says SpaceX making good progress on Starship’s upgraded Raptor 2 engines
As is routine, SpaceX CEO Elon Musk has taken to Twitter to offer a few details about the status of Starship, its Raptor engines, and a few upgrades planned for both.
In mid-December, Musk revealed even more ambitious plans to upgrade Starship by stretching its propellant tanks and adding another three Raptor engines, potentially boosting the ship’s maximum thrust by 50% and substantially improving payload performance. These latest details are focused on an upgraded version of the Raptor engine and on additional changes to Starship’s structural design and assembly process.
According to Musk, as SpaceX continues to ramp up ground testing of the upgraded engine variant, “Raptor 2 now operates routinely at 300 bar main chamber pressure.” For context, on February 10th, 2019, just days after SpaceX began testing the first full-scale Raptor prototype ever completed, the engine briefly reached a main combustion chamber pressure just shy of 269 bar (3900 psi). That narrowly beat records set by Russia’s RD-270 and RD-180 engines, the latter of which is used on ULA’s Atlas V.
It took 18 months before Musk revealed clear proof that at least one Raptor prototype sustained such high chamber pressures over a minute or more of steady-state operations. The same engine peaked at an impressive 330 bar (~4800 psi), briefly producing 225 tons (~500,000 lb) of thrust and soundly beating out Russia’s never flown RD-701 engine, which crested 290-300 bar in testing. Another ~18 months after that milestone, Raptor isn’t quite operational in the sense of supporting orbital-class launches but the engine isn’t far from its first and has since supported dozens of Starship static fires and seven flight tests – five of which occurred in a period of just six months.
Already, despite the fact that Raptor 1 or 1.5 engines have yet to even attempt an orbital-class launch, SpaceX has almost entirely moved on to a new and improved variant known as Raptor 2. According to Musk, all Raptor ground testing at the company’s McGregor, Texas development campus is now focused on the new hardware, which reportedly features much cleaner plumbing and wiring. The biggest change to Raptor 2, though, is an almost 25% increase in maximum nominal thrust over Raptor 1/1.5 – from around 185 to 230 tons (408,000-507,000 lbf). That’s partially enabled by widening the ‘throat’ of Raptor’s nozzle, which sacrifices a small amount of efficiency for more power density. However, Raptor 2 also contains design improvements throughout to enable sustained, reliable operation at chamber pressures up to 300 bar – 10% higher than Raptor 1.5.
On October 24th, Musk subtly live-tweeted one of the first Raptor 2 static fires, revealing that the engine reached a chamber pressure of 321 bar (~4650 psi) and briefly produced around 245 tons (~540,000 lbf) of thrust before destroying itself. Now, a little over two months later, Musk says that Raptor 2 prototypes are routinely operating at 300 bar without major issues, meaning that they can ignite and safely shut down after burning for several minutes at those pressures. In theory, given that 300 bar is Raptor 2’s targeted chamber pressure at max thrust, that means that the engine is now “routinely” operating at the level SpaceX wants and needs to take Starship to the next level.
It’s likely that one or several months of work remain before SpaceX can begin qualifying the first Raptor 2 engines (or, more importantly, hypothetical Raptor 2 Vacuum or Boost variants) for the first Starship or Super Heavy prototypes designed for the new engine. Nonetheless, the rapid progress SpaceX has made in the first few months of Raptor 2 testing is extremely encouraging.

Tesla needs to confront these concerns as its ‘wartime CEO’ returns: Wedbush
Tesla will report earnings for Q2 tomorrow. Here’s what Wedbush expects.

Tesla (NASDAQ: TSLA) is set to report its earnings for the second quarter of 2025 tomorrow, and although Wall Street firm Wedbush is bullish as the company appears to have its “wartime CEO” back, it is looking for answers to a few concerns investors could have moving forward.
The firm’s lead analyst on Tesla, Dan Ives, has kept a bullish sentiment regarding the stock, even as Musk’s focus seemed to be more on politics and less on the company.
However, Musk has recently returned to his past attitude, which is being completely devoted and dedicated to his companies. He even said he would be sleeping in his office and working seven days a week:

Nevertheless, Ives has continued to push suggestions forward about what Tesla should do, what its potential valuation could be in the coming years with autonomy, and how it will deal with the loss of the EV tax credit.

These questions are at the forefront of what Ives suggests Tesla should confront on tomorrow’s call, he wrote in a note to investors that was released on Tuesday morning:
“Clearly, losing the EV tax credits with the recent Beltway Bill will be a headwind to Tesla and competitors in the EV landscape looking ahead, and this cash cow will become less of the story (and FCF) in 2026. We would expect some directional guidance on this topic during the conference call. Importantly, we anticipate deliveries globally to rebound in 2H led by some improvement on the key China front with the Model Y refresh a catalyst.”
Ives and Wedbush believe the autonomy could be worth $1 trillion for Tesla, especially as it continues to expand throughout Austin and eventually to other territories.
In the near term, Ives expects Tesla to continue its path of returning to growth:
“While the company has seen significant weakness in China in previous quarters given the rising competitive landscape across EVs, Tesla saw a rebound in June with sales increasing for the first time in eight months reflecting higher demand for its updated Model Y as deliveries in the region are starting to slowly turn a corner with China representing the heart and lungs of the TSLA growth story. Despite seeing more low-cost models enter the market from Chinese OEMs like BYD, Nio, Xpeng, and others, the company’s recent updates to the Model Y spurred increased demand while the accelerated production ramp-up in Shanghai for this refresh cycle reflected TSLA’s ability to meet rising demand in the marquee region. If Musk continues to lead and remain in the driver’s seat at this pace, we believe Tesla is on a path to an accelerated growth path over the coming years with deliveries expected to ramp in the back-half of 2025 following the Model Y refresh cycle.”
Tesla will report earnings tomorrow at market close. Wedbush maintained its ‘Outperform’ rating and held its $500 price target.

Tesla Model Y becomes dual champ in China’s vehicle sales rankings
The Model Y’s recent accomplishments suggest that Tesla really has created something special with the all-electric crossover.

The Tesla Model Y was recently deemed a double champion in China, with the all-electric crossover topping two notable sales charts in the country’s automotive sector.
The Model Y’s recent accomplishments suggest that Tesla really has created something special with the all-electric crossover, as it has continued to outsell even vehicles that are newer and more affordable.
Tesla China’s announcement
In a post on Weibo, Tesla China VP Grace Tao highlighted that the Model Y topped China’s sales of SUVs, as well as vehicles that are priced in the 200,000-400,000 yuan range. This is quite remarkable, as the Model Y is one of the more costly entries in both lists. She also invited everyone to try out the vehicle for themselves. “You will know the champion strength after a try,” the Tesla VP wrote.
For the first half of the year, the Tesla Model Y sold 171,491 units domestically in China. This number was enough to make it the country’s best-selling SUV and vehicle priced in the 200,000-400,000 yuan range, but it could still easily be higher in the second half of 2025.
This was because Tesla initiated a changeover in Gigafactory Shanghai to shift the facility’s Model Y line to the vehicle’s new iteration. Had Tesla sold the Model Y in full force during the first half of 2025 in China, the vehicle’s domestic sales figures would have been even more impressive.
Model Y L coming
Tesla China’s Model Y sales could see a notable boost in the second half of the year due to the addition of the Model Y L, an extended wheelbase version of the all-electric crossover. Tesla is yet to announce the details for the Model Y L, though the vehicle was listed in the MIIT regulatory catalog as a six-seater. This is game-changing, as the Model Y’s previous seven-seat configurations have caught criticism for being far too cramped and unusable for adults.
With the six-seat Model Y in the company’s lineup, Tesla would be able to compete with popular vehicles from rivals like BYD, which have made it a point to release spacious three-row vehicles that are designed to carry the whole family. Provided that the Model Y L is priced correctly, it could very well raise Tesla’s vehicle sales this year.
