Porsche buys 10% stake in Rimac, tapping supercar-startup’s EV expertise
German automaker Porsche AG has taken a 10% stake in Croatian supercar startup Rimac Automobili, maker of the highly-anticipated and extremely exclusive C_Two all-electric supercar. With Porsche starting to dip its feet in the electric vehicle market with the Taycan (previously dubbed as the Mission E sedan), tapping into Rimac’s EV expertise would genuinely benefit the legacy automaker’s electric car initiatives.
Rimac has garnered a solid reputation over the years. Founded by Mate Rimac in 2009, Rimac Automobili became known as the maker of the Rimac Concept One, the world’s first $1 million all-electric supercar. Its successor, unveiled earlier this year as the Rimac C_Two, is even more impressive, with a 0-60 mph time of 1.85 seconds, a top speed of more than 250 mph, 1,914 horsepower, and a claimed driving range of 403 miles per charge. Rimac expects to manufacture 150 C_Twos during its production run, and as of April, the company revealed that the $2.1 million all-electric supercar was almost sold out.
In a statement, Porsche’s executive board deputy chairman Lutz Meschke remarked that the Croatian startup’s success with its first two vehicles were the credentials that genuinely impressed the German legacy carmaker.
“We feel that Rimac’s ideas and approaches are extremely promising, which is why we hope to enter into close collaboration with the company in the form of a development partnership. By developing the purely electric two-seaters super sports cars, like the Concept One or C_Two, as well as core vehicle systems, Rimac has impressively demonstrated its credentials in the field of electromobility,” the Porsche executive said.
Meschke’s statement about Rimac’s prowess in the development of vehicle systems rings true. Apart from producing all-electric supercars, after all, Rimac is also focused on the development of high-voltage battery technology and electric powertrains, as well as digital interfaces for EVs. Back in March, the Croatian supercar maker announced a deal with China’s Camel Group, a battery manufacturer, to build an electric motor and battery factory in the Asian country. Rimac also has a separate subsidiary focused on electric bicycles called Greyp Bikes.
Ultimately, Rimac CEO Mate Rimac noted that he considers the partnership with Porsche as a pivotal step forward for his company, as it becomes a component and systems supplier for the emerging EV market.
“This partnership now is an important step for Rimac on our way to become a component and system supplier of choice for the industry in electrification, connectivity and the exciting field of Advanced Driver Assistance Systems,” Rimac said.
The Rimac C_Two is expected to start production sometime in 2019, the same year that Porsche is set to roll out the Taycan. Considering the release date of the all-electric supercar, the C_Two would likely enjoy a year dominating the high-performance EV industry before it meets a formidable challenger — the next-generation Tesla Roadster — which is expected to start production sometime in 2020. The next-gen Roadster, which is priced at a more modest $200,000 – $250,000 for its base variant, costs just a fraction of the C_Two’s $2.1 million price tag. Performance-wise, the two vehicles are head-to-head, with the Roadster having a 0-60 mph time of 1.9 seconds and 10,000 Nm of torque compared to the C_Two’s 1.85 seconds and 2,300 Nm of torque.

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.
