It appears that Tesla’s challenges with a former Model 3 owner-turned-protester in China are not over just yet. On Thursday, the former Tesla owner, accompanied by her husband, formally filed a defamation suit against the EV maker. The lawsuit was filed at the Beiguan District People’s Court in Anyang, Henan Province.
In her litigation, Zhang, the former Model 3 owner claimed that a statement from Vice President Grace Tao and Tesla’s Beijing and Shanghai branches has resulted in abuse and mental stress for her family. She also accused the EV maker of publishing untrue statements to create a negative image of her as a customer who raised unreasonable requests.
Zhang demands an apology and RMB 50,000 (US$7,740) in compensation.
The former Tesla owner attracted international attention after she held a bold protest at the Shanghai Auto Show. Wearing a shirt claiming that Tesla’s brakes failed her, Zhang climbed on top of a Model 3 display unit inside the automaker’s booth. The former Model 3 owner loudly protested until she was taken away by security. She was later detained for several days for “disrupting public order.”
Zhang had already been butting heads with Tesla before her protest at the Shanghai Auto Show. After the vehicle’s crash was deemed as a result of reckless driving and not faulty brakes, the Tesla owner took actions against her local Tesla service center, refusing repair and insisting on a full refund instead, plus compensation for lost wages. The owner also declined Tesla’s offer to have the vehicle taken to a third-party agency for an examination.
-->Tesla Vice President Grace Tao later issued a strongly worded statement on Chinese social media, stating that “There is no possibility Tesla will compromise” and that the company “cannot meet unreasonable demands.” This triggered a wave of criticism against Tesla, including some from the Central Political and Legal Affairs Commission, a Communist Party body that oversees the country’s legal apparatus.
Tesla eventually issued an apology over its handling of the incident, stating that it will learn from this experience to improve its customer relations further. The company also established a “Special Handling Team” that would address special customer concerns.
“We apologize for failing to solve the problem of the car owner in time… Tesla respects and firmly obeys the decisions of relevant government departments, respects consumers, abides by laws and regulations, and resolutely actively cooperates with all investigations of relevant government departments. To this end, we have set up a special handling team, dedicated to special handling, and strive to meet the demands of car owners and strive to satisfy car owners while complying with laws and regulations,” Tesla wrote in Weibo.

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.
The upgraded link, which includes six daily services aligned with shift schedules, reduces travel time to roughly 35 minutes despite ongoing station construction. 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 new service will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory. 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,” Tesla stated. “The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory.”
-->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 upgrade follows earlier phases of Tesla’s self-funded shuttle 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 rely on 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 non-employees to ride the shuttle free of charge, making it a broader mobility option for the region as the site’s output and workforce continue to scale.

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.
