Tesla’s European Gigafactory 4 to begin construction as early as January 2020
Tesla’s Gigafactory 4 in Berlin, Germany will reportedly begin construction around January 2020. This comes just after Tesla reportedly reached an agreement with local government officials to purchase a piece of land where the company’s electric vehicle and battery production facility will be built.
CEO Elon Musk announced that Berlin would become the home of Tesla’s next vehicle production factory last month. A report from Deutsche Bank appearing to be published on December 9 states the company “expects construction to start in Berlin around January 2020 and will begin with Model Y production and then Model 3 will follow.” Following the announcement of Gigafactory 4 at the Golden Steering Wheel Awards in Germany, Musk tweeted that the factory “will build batteries, powertrains & vehicles, starting with Model Y.”

Tesla expects Model Y production at Gigafactory 4 to begin in 2021, or “a maximum of two years after the groundbreaking ceremony.” It is not known when Tesla will begin Model 3 production, nor is the exact dollar figure of how much the company will invest in the upcoming facility. However, there is speculation that the cost will be “slightly” higher than the estimated $2 billion investment Tesla had building Gigafactory 3 in Shanghai, as noted by the Shanghai Planning and Land Resources Administration.
According to Bild, Tesla’s purchase agreement for 300 hectares of land for production and logistics space will become valid following approval from Brandenburg’s Finance Committee. However, the electric car maker based out of Silicon Valley, California reportedly plans to begin building its new plant before approval is received. “Tesla is likely to start at his own risk even before the approval, if a positive decision can be expected,” Brandenburg Minister of Agriculture, Environment and Climate Protection Axel Vogel said.
Economy and Energy Minister Joerg Steinbach says the project is on schedule and “the building area is expected to be cleared by mid-March.” Steinbach and other government officials have been openly supportive of Tesla’s presence in Germany. Economy Minister Peter Altmaier was alongside Steinbach at a press conference in Potsdam, Germany following the announcement of Gigafactory 4, where they spoke highly about Tesla’s decision.
“We see it as recognition of Germany as a location for making cars. We think we now have the chance, in the coming years, to become an important international centre in this future-oriented sector,” Altmaier said.
Musk and Tesla saw several advantages in bringing the company’s new factory to Germany. “Everyone knows that German engineering is outstanding, for sure. That’s part of the reason why we are locating our Gigafactory Europe in Germany,” the Tesla CEO stated. Tesla expects Gigafactory 4 to assist in the production of its increasingly popular vehicles, especially the Model Y crossover, a vehicle that will be competing in the highly competitive crossover segment, which is among the most lucrative in the auto market.

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.
