Tesla Model 3 and Model S heated seats compared in temperature test showdown
One of the best things about Tesla’s vehicles is their capability to improve over time. Through over-the-air updates, Tesla’s electric cars receive safety enhancements, fun Easter Eggs, new convenience features, and even additional driver-assist capabilities free of charge. These improvements have been particularly notable in the Model 3, as the vehicle has progressively gotten better since it started rolling off the assembly line back in July 2017.
The Tesla Model 3 is the company’s most affordable vehicle today, with its range-topping Performance variant costing less than a Model S 100D. Since it was released, several improvements to the vehicle have been rolled out, from shorter braking distances (courtesy of Consumer Reports) to rear seat warmers. In the case of the latter, the warmers were even a point of discussion among Tesla owners prior to their activation, considering that the feature was absent on the vehicle when it was initially delivered to reservation holders.
By March last year, though, Tesla introduced heated rear seats for the Model 3, making the feature universal for all the cars in its lineup. Last December, Tesla released an update that made seat heating even more convenient, allowing owners to activate and set their vehicles’ seat warmers from the mobile app. For the company’s flagship cars — the Model S and Model X — even the steering wheel heaters could be activated from the Tesla app.
Inasmuch as the heated seats of the Model 3 are a welcome feature, though, it is still quite interesting to see how it stacks up against the excellent seat heaters in the more premium, albeit older, Model S. Having both cars, Tesla owner-enthusiast Erik Strait opted to conduct a test to compare the Model 3 and Model S’ seat heaters using a FLIR thermal camera. Needless to say, the test results were quite compelling.
As could be seen in the video, the Model 3’s heaters actually work well. Five minutes after activating the feature on the app, the Model 3’s seat heaters registered 73.3 degrees Fahrenheit on the back and 81.5 F on the bottom. That’s not too far from the Model S, which registered 69.2 degrees Fahrenheit on the back and 84.6 F at the bottom after 5 minutes of activation.
-->That said, the Model S’ heaters appear to have an advantage over the Model 3, thanks to the distribution of heat on the seat itself. The Model 3’s seat heater is pretty straightforward, with the changes in temperature being centered on the areas directly above the heating element. Thus, while the center portions of the seat warmed up well, other portions such as the sides remained noticeably cooler. The Model S’s heating element, on the other hand, appeared to be well-distributed, resulting in a more even temperature across the entire seat.
There would be more improvements coming to the Model 3 and Model S in the coming months. In the case of the flagship sedan, speculations are high that Tesla might update the vehicles’ batteries to newer, larger 2170 cells, which the company is using for the Model 3. With 2170 cells and more advanced cooling systems, the Model S would be even more impressive than it is today, despite being a benchmark for premium electric vehicles for years.

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.
