SpaceX CEO Elon Musk says first orbital Starship prototype will be done by June
SpaceX CEO Elon Musk says that the company’s first Starship prototype – a low-fidelity hop test vehicle – has finished assembly in South Texas, paving the way towards a series of experimental vertical take-off or landing (VTOL) hop tests that could begin as early as February or March 2019.
One step beyond the prototype currently rising out of the coastal Texas wetlands, Musk also indicated that the first orbital Starship prototype – essentially the spacecraft’s first full-fidelity test article – could be completed as early as June 2019, a truly extraordinary pace of development for a program as complex and cutting-edge as BFR.

Starhopper rising
Barely six weeks after work began on the massive Starship prototype, SpaceX’s Starhopper appears to have grown to its full ~40m (~130 ft) height in South Texas. Following a preliminary fit test on Tuesday, January 8th, workers made a second attempt on Wednesday and completed the final attachment of Starhopper’s upper and lower halves. Intriguingly, no time was wasted spot-welding the halves together after their successful docking, and an additional sheet of stainless steel has been welded over the seam in the hours since then.

However, what looks like 9m-diameter (~30 ft) steel tank domes are being assembled and welded together at the same SpaceX facility, despite the fact that no domes have been observed being installed inside Starhopper. Musk did seem to indicate that even Starhopper – requiring far less propellant than an orbital Starship – will still feature full 9m (~30 foot) diameter tanks. This could imply that the newly integrated Starhopper has yet to have propellant tank domes installed inside and will need to be taken apart again to allow for that critical final step. If that is not the case, the only possible explanation is that Starhopper’s propellant tanks will actually be less than 9m in diameter and will be lifted up through the vehicle’s aft for installation.
One last increasingly improbable possibility is that a significant portion of the hopper’s upper half will be or already is a pressure vessel capable of holding cryogenic propellant, although the process of actually watching the less than surgical fabrication does not inspire a great deal of confidence in any potential pressure vessel aspirations. In the meantime, we have been given the first look at what the outside of Starhopper will look like once complete. According to SpaceX CEO Elon Musk, hop tests of the imposing vehicle could begin as few as 4-8 weeks from now.

To orbit, and beyond!
Aside from offering the above photo and comparing Starhopper’s prospects to those of Falcon 9’s Grasshopper and F9R hop test articles (i.e. very suborbital and very short-lived), Musk also stated that the first orbital Starship prototype could be completed as early as June 2019, as few as three months after Starhopper’s first hop test. This paints at least a rough picture of the planning going on for BFR’s flight test regime, beginning with a suborbital hop test prototype, moving to a full-fidelity Starship capable of high-speed intra-atmospheric heat shield and aero surface testing, and finally full-up orbital testing with the completion of the first BFR booster (now known as Super Heavy).
Should be done with first orbital prototype around June

Both, but demo Starship is being built now, whereas Super Heavy hardware will start getting built in spring
— Elon Musk (@elonmusk) December 9, 2018
According to Musk, the first Super Heavy booster will begin production and assembly as early as spring 2019, while the CEO stated that he believed the odds of BFR (Starship/Super Heavy) reaching orbit by 2020 were 60% and “growing rapidly” thanks to a recent move from carbon composite tankage to stainless steel. If SpaceX and Musk keep putting their money where their mouths are and rapidly building test articles and prototypes, that orbital debut might actually be less insane than it sounds. We’ll find out soon enough.

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.

Elon Musk reveals what will make Optimus’ ridiculous production targets feasible
Musk recent post suggests that Tesla has a plan to attain Optimus’ production goals.
Elon Musk subtly teased Tesla’s strategy to achieve Optimus’ insane production volume targets. The CEO has shared his predictions about Optimus’ volume, and they are so ambitious that one would mistake them for science fiction.
Musk’s recent post on X, however, suggests that Tesla has a plan to attain Optimus’ production goals.
The highest volume product
Elon Musk has been pretty clear about the idea of Optimus being Tesla’s highest-volume product. 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-per-year line at the Fremont Factory.
Following this, Musk stated that Giga Texas will receive a 10 million-per-year unit Optimus line. But even at this level, the Optimus ramp is just beginning, as the production of the humanoid robot will only accelerate from there. At some point, the CEO stated that a Mars location could even have a 100 million-unit-per-year production line, resulting in up to a billion Optimus robots being produced per year.
Self-replication is key
During the weekend, Musk posted a short message that hinted at Tesla’s Optimus strategy. “Optimus will be the Von Neumann probe,” the CEO wrote in his post. This short comment suggests that Tesla will not be relying on traditional production systems to make Optimus. The company probably won’t even hire humans to produce the humanoid robot at one point. Instead, Optimus robots could simply produce other Optimus robots, allowing them to self-replicate.
-->The Von Neumann is a hypothetical self-replicating spacecraft proposed by the mathematician and physicist John von Neumann in the 1940s–1950s. The hypothetical machine in the concept would be able to travel to a new star system or location, land, mine, and extract raw materials from planets, asteroids, and moons as needed, use those materials to manufacture copies of itself, and launch the new copies toward other star systems.
If Optimus could pull off this ambitious target, the humanoid robot would indeed be the highest volume product ever created. It could, as Musk predicted, really change the world.
