Tesla case against Xpeng Motors over alleged Autopilot code theft faces roadblock
Tesla’s case against Chinese EV maker Xpeng Motors over the alleged theft of its Autopilot source code recently reached an unfortunate roadblock. In a recent update, a federal judge rejected a request from Tesla that would allow the company to access grand jury materials related to a former Apple engineer, who reportedly stole trade secrets before joining the Chinese EV maker.
Back in mid-January, Tesla subpoenaed XMotors, the US business unit of the China based Xpeng Motors. This was seen as a bid to gather evidence in its civil lawsuit against Cao Guangzhi, who previously worked on Tesla’s Autopilot team as an engineer. Guangzhi is accused of misusing Tesla’s intellectual property for the benefit of Xpeng, his new employer.
Tesla requested access to several materials, including the entire repository of Xpeng’s XPilot source code, referring to the Chinese EV maker’s own driver-assist system that is intended to rival Autopilot. The American electric car maker also requested access to clones of hard drives from Xpeng senior executives.
Interestingly enough, Tesla also requested access to court records related to a criminal charge against former Xpeng employee Zhang Xiaolang, who used to work for Apple. Like Cao, the former Apple employee is accused of stealing trade secrets before joining Xpeng. Unfortunately for Zhang, the Chinese EV maker opted to cut ties with him after criminal charges were filed.
It is these requests that were denied by a federal judge on Wednesday. In an announcement, US District Judge Vince Chhabria stated that the relevance of materials related to Zhang and Tesla’s claims against Cao was “speculative and tenuous.” “Discovery of this information is not proportional to the needs of this case at this time, especially given the potential for interference with an ongoing criminal prosecution, a concern raised by the US Attorney,” the US federal judge wrote, as noted in a TechNode report.
Apart from these, Tesla will also not be provided with images of work computers from several key Xpeng executives, including CEO He Xiaopeng and President Brian Gu. This was due to the executives being employed solely by China-based Xpeng Motors, not by the company’s US-based XMotors business unit. Tesla is not coming out of its requests empty handed, however. Xpeng is still required to produce the source code for its XPilot system. The source codes from XPilot and Autopilot are poised to be reviewed by a neutral third party, who will determine if any theft was indeed performed.
Xpeng has been pretty open about the fact that its business is inspired by Tesla, with the company stating that had used the American electric car maker’s patents to develop its vehicles. Its P7 sedan, which was recently revealed, is also poised to be a response to the Model 3, Tesla’s most successful car to date. Unfortunately, some of Xpeng’s actions in the past have suggested that the company’s inspirations from Tesla may go a bit deeper than expected. This is hinted at by the heavily Model S/X inspired interior of its vehicles, and the fact that its website seems to be a direct copy of Tesla’s configurator.

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.
