SpaceX preps Starship, Super Heavy for another week of Raptor testing
SpaceX continues to work around the clock to prepare its latest Starship and Super Heavy booster prototypes for another week of testing – likely focused on firing up the Raptor engines installed on each vehicle.
Known as Booster 7 and Ship 24, SpaceX has been slowly testing both prototypes for approximately four months, beginning in April and May, respectively. Only in early August did the company cautiously begin attempting to ignite their Raptor engines as part of a process known as static fire testing – by far the most difficult and important part of qualifying both vehicles for flight.
Thanks to progress made in 2021, SpaceX already has significant experience testing an earlier orbital-class Starship prototype on the ground, but the process of testing Ship 24 is still fresh and unfamiliar for a number of reasons. For Booster 7, the challenges are even greater.
On top of major design changes made to Starship and Super Heavy over the last year as SpaceX continues to refine the rocket, the company also developed a substantially different version of its Raptor engine. Compared to Raptor V1, Raptor V2 almost looks like a new engine and can produce around 25% more thrust (230 tons versus 185 tons). SpaceX has also tweaked how the engine operates, particularly around startup and shutdown, further weakening the value of past experience testing Raptor V1 and V1.5 engines on Ship 20 and Boosters 3 and 4.
In other words, with Ship 24 and Booster 7 engine testing, it’s possible that SpaceX is effectively starting from scratch. Many aspects of testing – propellant conditioning, thermal characteristics, tanking, detanking, certain test stands – are likely mostly unchanged, but almost every aspect of a rocket is affected by its engines.
Before SpaceX began testing Raptor V2 engines on Starship and booster prototypes, it wasn’t clear if the changes between V1.5 and V2 would invalidate a lot of prior testing. After the start of Booster 7 and Ship 24 static fire testing, it’s now clear that a lot of that earlier work has to be redone. It’s also clear that despite some of the simplifications in Raptor V2’s design, operating the engine on Starship and Super Heavy is much harder get get right.
Since mid-July, SpaceX has completed around 15-20 ‘spin-prime’ tests between Ship 24 and Booster 7 – more of that kind of test than any other prototype in the history of Starbase has performed. Spin-prime tests flow high-pressure gas through Raptor’s pumps to spin them up without igniting anything. It’s unclear why so many of those tests are being done, what SpaceX is gaining from it, or why the company appears to have completely stopped conducting preburner tests (a more life-like spin-prime with partial combustion).
Regardless, eight weeks after the start of engine testing, Booster 7 has only performed three static fires (two with one engine, one with a max of three or four engines), and Ship 24 has only completed one static fire with two engines. Before either vehicle can be considered ready for flight, a day that could easily never come, each will likely need to conduct multiple successful static fires with all of their Raptor engines (6 on S24 and 33 on B7).
If the pace of Booster 7 testing doesn’t change, the vehicle could be months away from a full 33-engine static fire attempt – perhaps the single most important and uncertain test standing between SpaceX and Starship’s first orbital launch attempt. Ship 24’s path to flight readiness should be simpler, but it appears to be struggling almost as much.
According to CEO Elon Musk, “an intense effort is underway” to ensure that Super Heavy B7’s Raptor engines are well contained during anomalies, so that one engine violently failing won’t damage or destroy the booster, other engines, or the launch pad. That could certainly complicate the process of testing Booster 7, and it’s likely that SpaceX is taking some of the same actions to protect Ship 24.
In early September, after a partially successful Booster 7 static fire (its first multi-engine test) and numerous additional Ship 24 tests that failed to achieve ignition, SpaceX replaced engines on both vehicles. Booster 7 had one of 13 Raptor Center engines swapped out, while Ship 24 had one of its three Raptor Vacuum engines replaced.
On September 5th, SpaceX distributed a safety alert to Boca Chica’s few remaining residents, confirming that it wants to restart testing as early as Tuesday, September 6th. Especially as of late, that alert guarantees nothing, but it does at least open the door for SpaceX if Ship 24, Booster 7, and the positions of the stars happen to be in the right mood between 8am and 8pm CDT. Additional opportunities are available on September 7th, 8th, 9th, and 12th.
Tesla is dominating in the United Kingdom so far through 2025, and with about two weeks left in the year, the Model Y and Model 3 are leading the way.
The Model Y and Model 3 are the two best-selling electric vehicles in the United Kingdom, which is comprised of England, Scotland, Wales, and Northern Ireland, and it’s not particularly close.
According to data gathered byย EU-EVs, the Model Y is sitting at 18,890 units for the year, while the Model 3 is slightly behind with 16,361 sales for the year so far.
The next best-selling EV is the Audi Q4 e-tron at 10,287 units, lagging significantly behind but ahead of other models like the BMW i4 and the Audi Q6 e-tron.
GOOD NEWS ๐ฌ๐ง Tesla is absolutely crushing the UK electric vehicle market in 2025 ๐ฅ
The numbers are in, and the dominance is clear. With an impressive amount of 42,270 vehicles delivered year-to-date, the brand now commands a solid 9.6% market share of the total auto market ๐โฆ pic.twitter.com/dkiGX9kzd0

The Model Y has tasted significant success in the global market, but it has dominated in large markets like Europe and the United States.
For years, it’s been a car that has fit the bill of exactly what consumers need: a perfect combination of luxury, space, and sustainability.
Both vehicles are going to see decreases in sales compared to 2024; the Model Y was the best-selling car last year, but it sold 32,610 units in the UK. Meanwhile, the Model 3 had reached 17,272 units, which will keep it right on par with last year.
Tesla sold 50,090 units in the market last year, and it’s about 8,000 units shy of last year’s pace. It also had a stronger market share last year with 13.2 percent of the sales in the market. With two weeks left in 2025, Tesla has a 9.6 percent market share, leading Volkswagen with 8 percent.
The company likely felt some impact from CEO Elon Musk’s involvement with the Trump administration and, more specifically, his role with DOGE. However, it is worth mentioning that some months saw stronger consumer demand than others. For example, sales were up over 20 percent in February. A 14 percent increase followed this in June.

Tesla Insurance officially expands to new U.S. state
Tesla’s in-house Insurance program first launched back in late 2019, offering a new way to insure the vehicles that was potentially less expensive and could alleviate a lot of the issues people had with claims, as the company could assess and repair the damage itself.
Tesla Insurance has officially expanded to a new U.S. state, its thirteenth since its launch in 2019.
Tesla has confirmed that its in-house Insurance program has officially made its way to Florida, just two months after the company filed to update its Private Passenger Auto program in the state. It had tried to offer its insurance program to drivers in the state back in 2022, but its launch did not happen.
Instead, Tesla refiled the paperwork back in mid-October, which essentially was the move toward initiating the offering this month.
BREAKING: Tesla Insurance has just officially launched in Florida.
This is the first new state to receive @Tesla Insurance in more than 3 years. In total, Tesla insurance is now available in 13 U.S. states (map in thread below of all the states).

Tesla’s in-house Insurance program first launched back in late 2019, offering a new way to insure the vehicles that was potentially less expensive and could alleviate a lot of the issues people had with claims, as the company could assess and repair the damage itself.
It has expanded to new states since 2019, but Florida presents a particularly interesting challenge for Tesla, as the company’s entry into the state is particularly noteworthy given its unique insurance landscape, characterized by high premiums due to frequent natural disasters, dense traffic, and a no-fault system.
Annual average premiums for Florida drivers hover around $4,000 per year, well above the national average. Tesla’s insurance program could disrupt this, especially for EV enthusiasts. The state’s growing EV adoption, fueled by incentives and infrastructure development, aligns perfectly with Tesla’s ecosystem.
Moreover, there are more ways to have cars repaired, and features like comprehensive coverage for battery damage and roadside assistance tailored to EVs address those common painpoints that owners have.
However, there are some challenges that still remain. Florida’s susceptibility to hurricanes raises questions about how Tesla will handle claims during disasters.
Looking ahead, Tesla’s expansion of its insurance program signals the company’s ambition to continue vertically integrating its services, including coverage of its vehicles. Reducing dependency on third-party insurers only makes things simpler for the company’s automotive division, as well as for its customers.

Tesla Full Self-Driving gets sparkling review from South Korean politician
“Having already ridden in an unmanned robotaxi, the novelty wasnโt as strong for me, but it drives just as well as most people do. It already feels like a completed technology, which gives me a lot to think about.”
Tesla Full Self-Driving got its first sparkling review from South Korean politician Lee So-young, a member of the country’s National Assembly, earlier this week.
Lee is a member of the Strategy and Finance Committee in South Korea and is a proponent of sustainable technologies and their applications in both residential and commercial settings. For the first time, Lee was able to utilize Tesla’s Full Self-Driving technology as it launched in the country in late November.
Her thoughts on the suite were complimentary to the suite, stating that “it drives just as well as most people do,” and that “it already feels like a completed technology.”

Her translated post says:
“Finally, today I got to experience Tesla FSD in Seoul. Thanks to the Model S sponsored by JiDal Papa^^, Iโm truly grateful to Papa. The route was from the National Assembly -> Mangwon Market -> Hongik University -> back to the National Assembly. Having already ridden in an unmanned robotaxi, the novelty wasnโt as strong for me, but it drives just as well as most people do. It already feels like a completed technology, which gives me a lot to think about. Once it actually spreads into widespread use, I feel like our daily lives are going to change a lot. Even I, with my license gathering dust in a drawer, donโt see much reason to learn to drive a manual anymore.”
Tesla Full Self-Driving officially landed in South Korea in late November, with the initial launch being one of Tesla’s most recent, v14.1.4.
It marked the seventh country in which Tesla was able to enable the driver assistance suite, following the United States, Puerto Rico, Canada, China, Mexico, Australia, and New Zealand.
It is important to see politicians and figures in power try new technologies, especially ones that are widely popular in other regions of the world and could potentially revolutionize how people travel globally.
