SpaceX wiggles Starhopper’s Raptor engine, tests parts ahead of hover test debut
On the evening of July 12th, SpaceX technicians put Starhopper’s freshly-installed Raptor – serial number 06 (SN06) – through a simple but decidedly entertaining test, effectively wiggling the engine in circles.
Designed to verify that Raptor’s thrust vectoring capabilities are in order and ensure that Starhopper and the engine are properly communicating, the wiggle test is a small but critical part of pre-flight acceptance and a good indicator that the low-fidelity Starship prototype is nearing its first hover test(s). Roughly 48 hours after a successful series of wiggles, Starhopper and Raptor proceeded into the next stage of pre-flight acceptance, likely the final more step before a tethered static fire.
Routine for all Falcon rockets, SpaceX’s exceptionally rigorous practice of static firing all hardware at least once (and often several times) before launch has unsurprisingly held firm as the company proceeds towards integrated Starhopper and Starship flight tests. Despite the fact that Raptor SN06 completed a static fire as recently July 10th, SpaceX will very likely put Starhopper and its newly-installed Raptor through yet another pre-flight static fire, perhaps its fourth or fifth test this month.
Although it would undoubtedly be easier, cheaper, and faster to skip that post-delivery static fire, it will simultaneously lower the risk of Raptor failing mid-flight and verify that Starhopper itself is healthy and ready for untethered hovering. Although SpaceX could likely live without Starhopper in the event that it’s lost during flight-testing, any failure capable of destroying the vehicle itself is at least as capable of severely damaging or completely destroying the spartan but still expansive test and launch facilities the company built over the course of several months.
Would you like some testing with your testing?
Follow July 12th’s nighttime Raptor wiggle test, July 13th was mainly quiet and filled with inspections of Starhopper, Raptor, and other various work. The day after, however, SpaceX proceeded through several hours of propellant loading, ending with what looked like less energetic versions of the Raptor preburner ignition tests Starhopper previously performed with Raptor SN02.
In a staged-combustion engine like Raptor, getting from the supercool liquid oxygen and methane propellant to 200+ tons of thrust is quite literally staged, meaning that the ignition doesn’t happen all at once. Rather, the preburners – essentially their own, unique combustion chambers – ignite an oxygen- or methane-rich mixture, the burning of which produces the gas and pressure that powers the turbines that bring fuel into the main combustion chamber. That fuel then ignites, producing thrust as they exit the engine’s bell-shaped nozzle.
Although the fireworks are so subtle that they are easily missed, the conditions inside the preburner – hidden away from view – are actually far more intense than the iconic blue, purple, and pink flame that exists Raptor’s nozzle. This is because the preburners have to nurture the conditions necessary for the pumps they power to fuel the main combustion chamber. Much like hot water will cool while traveling through pipes, the superheated gaseous propellant that Raptor ignites to produce thrust will also cool (and thus lose pressure) as it travels from Raptor’s preburner to the main combustion chamber.
Thus, if the head pressure produced in the preburners is too low, Raptor’s thrust will be (roughly speaking) proportionally limited at best. At worst, low pressure in the preburners can completely prevent Raptor from starting and running stably and can even trigger a “hard start” or shutdown that could damage or destroy the engine. As such, to preburners fundamentally have to operate at higher chamber pressures (and thus higher temperatures) than the main combustion chamber (the big firey bit at the end). According to Elon Musk, Raptor’s oxygen preburner has the worst of it, operating at pressures as high or higher than 800 bar (11,600 psi, 80 megapascals).
Coincidentally, this is roughly equivalent to the pressure at the bottom of the Pacific Ocean.
In short, preburner testing is no less critical than full-on static fire testing with an engine like Raptor. July 14th’s test was also made doubly efficient due to the fact that preburner testing requires liquid propellant, which effectively makes the whole test a wet dress rehearsal (WDR) even before any engine ignition or partial ignition is involved. Per SpaceX moving from propellant loading to preburner/turbine testing, Starhopper is almost certainly healthy and operating as expected, an excellent sign that the ungainly vessel may be ready for a static fire of Raptor as early as 2pm CT, July 15th.

Tesla Model Y Performance gets positive review from Swedish auto outlet
The refreshed Model Y Performance model receives unique bumpers, red brake calipers, new wheels, and a carbon fiber spoiler.
It appears that Tesla has created something special with the new Model Y Performance. The vehicle, which was released earlier late August, has started receiving rave reviews, some of it even from publications that tend to be critical of the EV maker and CEO Elon Musk.
Model Y Performance impressions
Swedish automotive outlet CarUp.se has given the updated Tesla Model Y Performance high marks, highlighting its redesigned sport seats as a standout improvement. Tesla implemented a number of key improvements to the Model Y Performance, such as its redesigned sports seats, which now feature powered thigh extensions like those found in the Model Y L from China.
To summarize, its review, the publication noted that “In addition to making you sit like a king, (the Model Y Performance) is also extremely fast at red lights.” The publication highlighted that “the exterior of the Tesla quickly reveals that it is a Tesla Performance model and there is no doubt that it is a really good-looking electric car.” This is quite impressive considering that the previous-generation Model Y Performance looked quite tame compared to the Model S and X Plaid and the Model 3 Performance.
Tweaks and improvements
The refreshed Model Y Performance model receives unique bumpers, red brake calipers, new wheels, and a carbon fiber spoiler, which together give the crossover a more athletic appearance. Performance badging and projection lighting further distinguish it from other Model Y variants. Inside, the upgraded front sport seats deliver noticeably improved support compared to the standard version, enhancing the vehicle’s balance of comfort and sportiness.
The new Model Y Performance deliver 460 horsepower and a top speed of 250 km/h, while consumption is listed at 16.2 kWh/100 km and range at 580 km WLTP. The crossover also benefits from adaptive suspension with preset damping modes. Manufactured at Gigafactory Berlin-Brandenburg, the Model Y Performance is currently available in Europe and the Middle East, with deliveries expected to start in the next 1-2 months.

Tesla Model Y leads sales rush in Norway in August 2025
The surge was led by the new Tesla Model Y, which has proven to be quite successful in the European country.
Tesla posted strong results in Norway this August. The surge was led by the new Tesla Model Y, which has proven to be quite successful in the European country.
Tesla’s excellent August
Data aggregated by TeslaStats.no suggested that Tesla saw 2,959 vehicle deliveries in August. This represents a notable 38.59% year-over-year increase compared to the 2,135 vehicles that were delivered by the electric vehicle maker in August 2024. Estimates from EU-EVs also indicated that Tesla sold 2,450 Model Ys in August 2025, making it the country’s top model.
Tesla’s domination in Norway was so notable that even with several days left in August, Swedish automotive outlet CarUp estimated that Tesla already held about 22% of the country’s auto market. This was very impressive considering that Tesla saw headwinds in Europe earlier this year due to the changeover to the New Model Y and negative sentiments about CEO Elon Musk.
Existing momentum
Tesla’s momentum in Norway has been notable for some time. In June, registrations rose 54% year-over-year, according to the Norwegian Road Federation (OFV). The Model Y was the standout, recording a 115% increase compared to the same month in 2023. Growth was even sharper in May, when Tesla sales surged 213%, CNBC noted.
Christina Bu, secretary general of the Norwegian EV Association (NEVA), attributed the brand’s success to the refreshed Model Y and its practical appeal. “I think it just has to do with the fact that they deliver a car which has quite a lot of value for money and is what Norwegians need,” Bu said. She pointed to features such as spacious cargo capacity, all-wheel drive, towing capability, higher ground clearance, intuitive digital systems, and Tesla’s established charging network as key factors.

Tesla dominates JD Power tech survey with double VW’s score, but gets no award
Tesla was not eligible for awards because the company did not “meet study award criteria.”
Tesla has emerged as the clear leader in JD Power’s latest technology survey, dominating with a score twice that of veteran automakers like Volkswagen.
This was despite Tesla not receiving any official awards in the survey due to eligibility issues.
Survey results
As per JD Power, its 2025 U.S. Tech Experience Index (TXI) Study collected responses from 76,230 owners of new 2025 model-year vehicles. This was the 10th year that the auto firm has conducted its study. Based on the raw scores of automakers in the survey, Tesla was the clear winner with a rating of 873 points out of 1,000. As noted in a CarUp report, Tesla’s ratings was more than twice as much as veteran automakers like Volkswagen or Toyota, which scored 432 and 436 points, respectively.
Rivian ranked second in the results with an impressive 730 points out of 1,000. That being said, JP Power noted in its press release that both Tesla and Rivian, the two highest-scoring automakers in its survey, are not eligible for awards because the companies do not “meet study award criteria.” In its report, CarUp alleged this criteria required automakers to be sold in all U.S. states.
As a result, Genesis was officially awarded the top rank in JD Power’s study despite its 538 score. Following Genesis was Cadillac, which received a score of 526, and Lincoln, which received a score of 523 out of 1,000.
Driver insights
According to JD Power, technology-related problems reported by drivers decreased by 6.3 per 100 vehicles compared to last year, contributing to a stronger user experience overall. Respondents identified automatic climate control as one of the most appreciated features, thanks to its ability to manage heating, ventilation, and air conditioning seamlessly.
“Smart technology not only seems to anticipate the driver’s needs but also reduces the cognitive workload and some of the difficulties that drivers face with digital systems,” said Kathleen Rizk, senior director of technology at JD Power.
Car wash mode, a feature meant to prepare vehicles for automated cleaning, was a frequent source of frustration due to its placement within infotainment menus. Drivers also voiced concerns over recognition systems that occasionally malfunction. In contrast, the blind spot camera received widespread praise, with 93% of drivers reporting regular use and 74% stating that they would like the feature in future vehicles.
