SpaceX Starship prototype ready for record-breaking tests
Over the weekend, SpaceX has installed the last of its first orbital-class Starship’s six Raptor engines, setting the prototype up for one or several record-breaking tests later this week.
Tentatively scheduled as early as 10am to 6pm CDT on Monday Tuesday, November 1st 2nd, the next test up on Starship 20’s (S20) docket will likely be its third static fire in eleven days. Ship 20 completed its first Raptor-involved test – known as a preburner test – on October 19th, followed by two successful back-to-back static fires – one with one Raptor and one with two – on October 21st.
Less than 36 hours later, the Starship’s two missing Raptor Center (RC) engines (of a total of three) had been installed by Friday morning, October 22nd. For unknown reasons, no testing was completed the following week it and it took SpaceX another six and a half days to deliver the final two missing engines to the pad for installation on S20. Regardless, both missing Raptor Vacuum engines were installed by 2am CDT on Saturday, October 30th, marking the second time a Starship prototype has had all six Raptors installed.
While it might be the second time SpaceX has installed six Raptors on a Starship, it’s likely the first time six engines have been fully integrated with Ship 20’s propellant tanks, gas supplies, and avionics. How exactly SpaceX plans to proceed is unclear but odds are good that Starship S20’s next static fire test campaign will involve simultaneous igniting at least four of its six Raptor engines, setting a new record for the number of Raptors simultaneously ignited.
More likely than not, though, Ship 20’s next campaign will culminate in the simultaneous ignition of all six Raptors to (hopefully) complete the first true orbital-class Starship static fire. Like SpaceX has only just begun to do with Falcon boosters, flight-proven Starships might eventually be able to skip preflight static fire tests, but it’s virtually guaranteed that SpaceX will still proof test Starship and Super Heavy before flights until ships, boosters, and Raptors have stable designs with substantial flight experience. To ensure full-fidelity testing, those static fires will always have to qualify all installed engines. That includes Starship, which is designed to burn both its sea-level and vacuum-optimized Raptors from booster separation to orbit.
At full throttle, depending on the efficiency of its three RVacs at sea level, Starship S20’s six Raptor V1.0 engines could produce ~1100 tons (~2.4M lbf) of thrust. By comparison, SpaceX’s workhorse Falcon 9 rocket produces around 760 tons (~1.7M lbf) of thrust at liftoff, meaning that Starship will likely become the most powerful single-core rocket the company has ever tested even if it never throttles above ~70%.
There’s a good chance that SpaceX will start Ship 20’s next round of tests by separately firing both sets of three Raptor Center and Vacuum engines or with a mixed three or four-engine test to follow the latest two-engine test. SpaceX could also take the most iterative approach and test three, four, and five engines at a time before the final six-engine test. Regardless, virtually all possible static fire tests Ship 20 is now configured to perform will be program ‘firsts’ of some kind.

Elon Musk makes a key Tesla Optimus detail official
“Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote on X.
Tesla CEO Elon Musk just made a key detail about Optimus official. In a post on X, the CEO clarified some key wording about Optimus, which should help the media and the public become more familiar with the humanoid robot.
Elon Musk makes Optimus’ plural term official
Elon Musk posted a number of Optimus-related posts on X this weekend. On Saturday, he stated that Optimus would be the Von Neumann probe, a machine that could eventually be capable of replicating itself. This capability, it seems, would be the key to Tesla achieving Elon Musk’s ambitious Optimus production targets.
Amidst the conversations about Optimus on X, a user of the social media platform asked the CEO what the plural term for the humanoid robot will be. As per Musk, Tesla will be setting the plural term for Optimus since the company also decided on the robot’s singular term. “Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote in his reply on X.
This makes it official. For media outlets such as Teslarati, numerous Optimus bots are now called Optimi. It rolls off the tongue pretty well, too.
Optimi will be a common sight worldwide
While Musk’s comment may seem pretty mundane to some, it is actually very important. Optimus is intended to be Tesla’s highest volume product, with the CEO estimating that the humanoid robot could eventually see annual production rates in the hundreds of millions, perhaps even more. Since Optimi will be a very common sight worldwide, it is good that people can now get used to terms describing the humanoid robot.
-->During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-Optimi-per-year production line at the Fremont Factory. Giga Texas would get an even bigger Optimus production line, which should be capable of producing tens of millions of Optimi per year.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.
