CEO Elon Musk has implicitly revealed that SpaceX recently conducted the first test of Starship’s new Raptor 2 engine.

Aside from kicking off integrated static fire testing of a refined, operationalized version of Raptor, the first prototype may have briefly become the most powerful engine of its kind ever tested before destroying itself. While not quite as successful as the first static fire campaign of a full-scale Raptor 1 engine, which survived several tests, the first Raptor 2 prototype’s early demise is still a routine part of engine development and is the start of a process that should ultimately produce a Super Heavy booster with 50% more thrust than the next most powerful rocket ever flown.

Prior to last weekend, it’s likely that competitor Blue Origin’s BE-4 – still in development and hoped to one day power ULA’s Vulcan and the company’s own reusable New Glenn – was the most powerful methane/oxygen rocket engine ever tested. BE-4 is designed to produce up to 244 tons (~539,000 lbf) of thrust. On its very first static fire, it appears that SpaceX’s first finished Raptor 2 prototype has narrowly stolen BE-4’s crown, briefly generating main combustion chamber pressures of 321 bar (~4650 psi) and as much as 245 tons (~540,000 lbf) of thrust.

To BE-4’s credit, the engine (at least as far as Blue Origin’s sparse public communications go) didn’t destroy itself after its first full-thrust static fire. Raptor 2 wasn’t so lucky and apparently exploded before completing its first test. There’s also some ambiguity as Blue Origin’s own website pegs BE-4 thrust at “2400 kN (550,000 lbf)” when 2400 kilonewtons is actually equivalent to 539,000 lbf. Regardless, designed to produce up to 230 tons (~510,000 lbf) of thrust in flight, Musk has said that Raptor 2 or V2.0 “is a major improvement in simplification” over Raptor 1, which nominally produces up to 185 tons (~410,000 lbf) of thrust at chamber pressures closer to 270 bar (~3900 psi).

It’s not all that surprising, then, that the first Raptor 2 prototype ever completed exploded when SpaceX pushed it to almost 107% of its maximum rated thrust and main chamber pressure during its first test.

Though impressive, SpaceX has technically pushed Raptor 1 prototypes further – and without failure. Musk later indicated that there was some damage present but a fairly young Raptor 1 engine still made it all the way up to 330 bar (~4800 psi) and spent about 10 seconds at chamber pressures above 320 bar without failure during an August 2020 stress test. Still, had the Raptor 2 prototype also made it to 330 bar, it would have produced around 252 tons (555,000 lbf) of thrust – 12% more than its Raptor 1 predecessor.

Super Heavy boosters will ultimately have 33 more or less identical sea-level-optimized Raptors – 13 Raptor Center (RC) engines with thrust vectoring and 20 Raptor Boost (RB) engines without. (NASASpaceflight – bocachicagal)

According to Musk, the main differences between Raptor 1 and Raptor 2 are “much cleaner” plumbing and wire harnesses and a wider combustion chamber throat, which allows the engine to produce more thrust in roughly the same package at the cost of a slight efficiency loss. Over the last two years, the CEO has mentioned the possibility of a power-optimized Raptor variant with up to 300 tons of thrust but in recent months, Musk says SpaceX has decided to keep the Raptor family as streamlined as possible and opted for just two variants – one with a sea-level nozzle (Raptor Center and Boost) and one with a larger vacuum-optimized nozzle (RVac).

Tesla’s retail sales in China climbed to 71,525 vehicles in September, the company’s second-highest monthly total this year, as per data from the China Passenger Car Association (CPCA). 

The result reflects a steady rebound, narrowing Tesla’s year-on-year sales decline to just 0.93%, while showing a 25% jump from August’s weaker numbers. Tesla’s September numbers are just below the 74,127 units that were sold domestically in March.

Tesla China’s September

Despite the uptick, Tesla China’s retail sales have now logged seven months of year-on-year declines this 2025, managing growth only in March and June, though a good portion of these lost sales was due to the changeover to the new Model Y. The Shanghai Gigafactory, which produces both the Model 3 and Model Y, continues to serve as a dual-purpose hub for domestic and export markets.

In September, Tesla exported 19,287 vehicles from its Shanghai facility, up 19.6% year-on-year but down 25.9% from August, as noted in a CNEV Post report. This is in line with Tesla China’s strategy of prioritizing exports early in each quarter. Including exports, Tesla China’s total wholesale volume reached 90,812 units in September, up 2.82% year-on-year and 9.16% month-on-month.

Model Y still leads

The Tesla Model Y still led the electric vehicle maker’s sales in China with 59,907 units sold wholesale during the month, rising 17.1% from last year, while Model 3 reached 30,905 units, dipping 16.8% year-on-year but up 27% from August. Tesla’s overall market share in China’s NEV segment rose to 5.52%, and its BEV share climbed to 8.66%, modest gains hinting at the company’s resilience in a fiercely competitive market.

Across Q3, Tesla sold 169,294 vehicles in China, down 6.9% year-on-year, marking its second consecutive quarterly decline but a strong 31.4% recovery versus Q2. Year-to-date, Tesla’s retail total stands at 432,704 units, down 5.97% compared to last year.

Elon Musk teases ‘Banish’ feature to pair perfectly with Summon

Tesla has long promised the possibility of completely hands-off parking: arrive, drop off at the entrance, the car parks itself, and the car retrieves you at the end of your visit.

Elon Musk has once again teased the “Banish” feature that could come to Tesla vehicles in the near future. It would be a perfect pairing to the popular Assisted Smart Summon (ASS), which the company launched earlier this year.

Banish has been something Tesla has teased for years. The company has promised the possibility of completely hands-off parking: arrive, drop off at the entrance, the car parks itself, and the car retrieves you at the end of your visit.

Ultimately, even though it is technically a driverless feature, Tesla has not refined its parking portion of the Full Self-Driving (Supervised) suite enough to release Banish to the public.

Tesla recently started performing specified parking tasks at the driver’s discretion. In the FSD (Supervised) v14.1 release, Tesla has added the ability to pick your parking scenario. Drivers can choose a Charger, Parking Lot, Curbside, Street, Driveway, or Parking Garage.

To achieve Banish, Tesla would have to gather enough data with these scenarios to then gain the capability to park after dropping vehicle occupants off.

However, CEO Elon Musk recently hyped Banish to the point of stating Teslas will be capable of it “in the near future.”

His remark came in response to a video where FSD v14.1 drove around a Costco parking lot for twenty minutes looking for a spot:

Summon is a feature that has given Tesla its challenges, but the release of Assisted Smart Summon (ASS) has improved some of its capabilities.

I tested it after receiving v14.1, and it did a great job of taking the correct route and driving safely to my location:

There will likely be some time between now and when Tesla is able to release Banish. As previously noted, Tesla will need to collect enough data from real-world scenarios and obtain a proven track record of being able to handle lots and parking in a variety of environments while supervised.

Tesla faces new blockade in Sweden as IF Metall escalates dispute

The action takes effect October 15 and will remain in place until Tesla signs a collective agreement.

Just over a month after the Swedish Meditation Institute threw in the towel on Tesla and IF Metall’s conflict, the labor union has announced a new industrial action aimed at disrupting the electric vehicle maker’s operations in the country. 

Potential Tesla disruptions

The latest news involves a total work stoppage by Linde Material Handling, one of Sweden’s largest forklift companies, which services industrial clients nationwide. The action takes effect October 15 and will remain in place until Tesla signs a collective agreement, as noted in a Dagens Arbete (DA) report.

The stoppage will halt all forklift-related work Linde performs for Tesla’s local subsidiary, TM Sweden, including maintenance, repair, and service of trucks used across its facilities. Simon Petersson, IF Metall’s contract secretary, shared described the union’s latest effort in a comment to the publication.

“We know that Tesla has trucks in several locations and that they are in need of service, maintenance and repair. We are stopping that now. For Linde, this is not a big deal. They service trucks for a lot of companies and Tesla is a small player in their portfolio,” Petersson noted.

Not a sure strategy

Whether IF Metall’s latest effort will succeed against Tesla remains to be seen, especially since the electric vehicle maker has been pretty firm in its stance that its employees do not need a collective agreement. Still, the IF Metall contract secretary stated that Linde’s strike against Tesla should make it more difficult for the electric vehicle maker to operate its business in Sweden.

“It remains to be seen. But as I have said before, it is about many small streams. This stops everything Linde does for Tesla. So not only with them, but regardless of where the work takes place. So if Tesla has problems with a truck, they will not have it repaired or serviced,” Petersson stated.

Following the decision of the Swedish Meditation Institute to end the negotiations between IF Metall and Tesla early last month, the union noted that it would still try to pressure the EV maker to sign a collective agreement. Since then, the Electricians union, as well as the postmen’s unions Seko and ST have continued to initiate blockades against Tesla Sweden.
