Tesla’s Giga Berlin production facility will revolutionize the electric automaker’s presence in the highly-concentrated European electric vehicle market. While Tesla holds considerable advantages in EV tech, pricing, range, and performance, it holds another considerably important element that determines a company’s ability to control pricing: battery production. With Tesla planning to manufacture its newly-detailed 4680 cells at the Berlin Gigafactory within two years, according to Economy Minister Jörg Steinbach, the company is setting the stage to infiltrate the intensely-competitive European EV market with the best and most affordable electric cars on the continent in record time.
After being approved for a slice of the $3.5 billion assistance package for the development of Giga Berlin’s 4680 battery plant, Tesla is set in a prime position to dominate the European battery production market. CATL and BASF SE both have large-scale battery manufacturing projects in Germany already, but Giga Berlin’s plant could displace them as Elon Musk once said it could be the biggest in the world.
During the 2020 European Battery Conference in November 2020, Musk said:
“I think it will be the largest. It would be capable of over 100 GWh hours per year of production and then possibly going to 200 to 250. I’m pretty confident at that point it would be the largest battery-cell plant in the world.”
And Tesla will need it. After coming off of a record year in deliveries and production figures, Tesla is continuing to ramp scalability as it tackles international markets for the first time in its history. After expanding to China with its Giga Shanghai plant, which began delivering cars in January 2020, Tesla had already started developing the Giga Berlin property by excavating the grounds and clearing obstacles that were there previously. Now, the factory is well underway and is expected to begin producing cars this Summer.
-->There still is no exact timeline for the 4680 battery plant, as it could take several years to figure out supply chain details from suppliers to Berlin. Tesla is also still figuring out the manufacturing processes of the 4680 cell at its Kato Road facility in Northern California. Elon Musk has said in the past that 4680 cells have been in working vehicles for some time, but at what scale? Only Tesla knows.
However, Jörg Steinbach, a vocal supporter of Tesla’s Berlin facility, now says the plant could open in two years, Bloomberg reported.

Despite regular hurdles to jump through, Tesla has had assistance from politicians all over Germany. With Steinbach’s support, another Economic Minister, Peter Altmaier, also extended his hand to the electric automaker, offering any help he can to expedite the factory’s construction. Environmental concerns, along with complaints from local citizens, have tied up Tesla from time to time at the factory. Still, construction has been moving along at an impressive rate since the official groundbreaking.
-->“You have to sometimes translate the culture of our approval procedures, which are also strongly influenced by environmental protection,” Steinbach said.
It is crucial for Tesla to open Giga Berlin so it can expand its outreach in the most EV-concentrated region on Earth. Steinbach says he is “totally relaxed” regarding the plant’s ultimate approval. He still expects EVs to roll off the line in July.
After the 4680 cell plant does open, Tesla will be able to scale-back costs of its EVs. Currently buying many cells from third-party suppliers, Tesla will still do that for the foreseeable future, according to Musk. However, creating more battery cells will decrease the shortage of batteries, making them less expensive and, at the same time, decreasing the price of Tesla’s cars. Because of this important point, the 4680 facility is of utmost importance.
“This project is given top priority,” Steinbach said.

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.
