Tesla is not ahead in lithium-ion battery tech, says Audi CEO: ‘We’re catching up’
There are very few automakers in the market today that is as serious about electric car battery tech as Tesla. Over the years, Tesla has been hard at work improving its batteries, and as the company heads towards its highly anticipated Battery Day event, it is becoming more and more evident that the electric car maker is one of, if not the, leader in lithium ion batteries for electric cars.
That is, of course, if one does not ask Audi CEO Markus Duesmann. In a recent talk with German magazine Focus.de, the Audi CEO, together with Bavaria’s Prime Minister Markus Söder, talked about the advent of electric mobility, the end of gas powered cars, and up and coming automakers like Tesla.
Both the Prime Minister and the Audi CEO noted that the pandemic will likely accelerate change in the auto industry. With the world having been shaken by the virus, Germany actually has a chance to recapture some of the market that it has lost to other automakers. The country’s car industry, after, all is in a crisis, with 46% of employees still on short-time work as of June.
To accomplish this, Söder noted that it would be necessary for the country’s auto industry to take a “real quantum leap.” “The time of the classic humming-humming car with a lot of horsepower is over,” he said. Audi CEO Duesmann, for his part, noted that mobility can only be solved with technology, and that digitization must be driven forward.
With the talk surrounding next generation vehicles powered by sustainable solutions, the moderator of the talk asked the Audi CEO and the Prime Minister if Tesla has already overtaken Germany’s best. To this question, Duesmann had a ready retort. The CEO stated that he does not see Tesla being ahead in lithium ion battery tech at all. With this, it would not be long before Germany’s automakers catch up. “We’re catching up with seven-mile boots,” Duesmann said.
The Prime Minister was in agreement, stating that he also does not see Tesla being far ahead. Söder did state that he is a great admirer of Tesla CEO Elon Musk’s work in the space industry. But in terms of the auto market, other companies can do what Tesla can accomplish, and Germany’s carmakers may even be ahead in some aspects. “Tesla is not bad, but others can do it too. We can stay ahead in engineering,” the Prime Minister remarked.
Interestingly enough, it will only be a matter of time before Tesla manages to capitalize on Germany’s car making mastery. The electric car maker is currently building Gigafactory Berlin, a facility that is expected to start operations next year by producing the Model Y.
As noted by Spiegel Online in a report about the crossover, the vehicle is nearly perfect, and it is only weighed down by its build quality, which still falls below Germany’s best. But with Gigafactory Berlin in the picture, Tesla customers in the region could look forward to acquiring vehicles with classic German build quality and the renowned tech of Tesla.

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.
