Tesla is partnering with a little-known casting company for Giga Press development
Tesla is partnering with Exco Technologies Limited, a Canadian company that specializes in designing and developing dies, molds, assemblies, and casting for automotive companies, the company’s CEO confirmed on an Earnings Call earlier today.
Tesla has long had a focus on manufacturing efficiencies, and arguably the most efficient, and most popular, was the introduction of the Giga Press. The Giga Press is a massive casting machine developed by Italian company IDRA, which helps Tesla cast the chassis and bodies of its all-electric vehicles in a swift, efficient, and non-time-consuming manner. Tesla has worked with IDRA to develop massive Giga Press machines that will be used at Gigafactory Texas and Gigafactory Berlin. There are already Giga Press machines working at Tesla’s Fremont factory in Northern California.

Now it appears that Tesla’s partnership for casting and molding technologies is going far beyond IDRA. Earlier today, Exco Technologies held its Q3 2021 Earnings Call, where it detailed how Tesla is revolutionizing the manner of automotive manufacturing throughout the entire sector. CEO Darren Kirk said (via Seeking Alpha):
“One key trend that will continue to benefit Exco is the increasing size in complexity of die-cast aluminum components. Tesla has really pushed the envelope on this front using massive Giga Presses, which are much larger die-cast machines than those used previously. This enabled Tesla to cast entire sub frames of the vehicle in one shot with Giga castings, rather than assemble numerous stamped metal components in the body shop, creating significant space and manufacturing efficiency gains. The tooling required to facilitate this process is very large and extremely complex, limiting the number of players able to compete effectively. Our Castool division is already the primary supplier of all shot and tooling for Tesla’s Giga Presses globally. This provides a clear indication of the depth we have in the design and know-how required to meet the challenges of the industry. We expect traditional OEMs will follow Tesla’s lead in using this larger die-cast machines as they transition to an EV future.”
-->Kirk said that its Castool division, which is a casting and stamping entity owned by Exco, is already supplying Tesla’s Giga Presses with shot-end tooling parts. Kirk stated that he expects Exco’s relationship with Tesla to continue to thrive, especially as Gigafactory Texas and Gigafactory Berlin are concerned.
Kirk also indicated that Exco is involved with Tesla through “all of its divisions,” but he wouldn’t detail explicit evidence that would show how Tesla is being helped by Exco, other than with shot-end tooling. Peter Sklar, an analyst at BMO Capital asked how the two companies were working together, and Kirk stated, “Well, I am not going to speak to whose providing those molds today, but I will say that all of our divisions are involved with Tesla at some level. And they are an important and growing customer across the board, and we see significant opportunity to expand on that.”
Casting could perhaps be Tesla’s biggest advantage as it continues to ramp up manufacturing and assembly efforts at its facilities. Casts for each of its vehicles can be made in a matter of a few seconds, effectively revolutionizing the way automotive bodies are made. Tesla has also shown that casting will play a pivotal role in the company’s decision to move to a structural battery pack, which will increase safety and vehicle rigidity in the event of an accident.

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.
