Tesla to shut down Model S and Model X lines for rumored design “refresh”
Recently leaked emails from Tesla CEO Elon Musk have revealed that the electric car maker intends to shut down the Model S and Model X line at the Fremont Factory for 18 days starting December 24, 2020. The reasons behind the halt in the flagship sedan and SUV’s production were not specified by the company, though speculations suggest that the 18-day halt may be used to introduce some much-needed hardware updates for the Model S and Model X.
In one of his emails, a copy of which was retrieved by CNBC, Elon Musk announced that Tesla employees working on the Model S and X line will be offered a full week of pay to cover 7 of the 18 days that will be affected by the shutdown. The CEO also encouraged the affected workers to volunteer and help out in the company’s Q4 delivery efforts.
Following is Elon Musk’s email in full:
Subject: S/X Holiday Shutdown
Hi Team,
-->The SX lines will be shut down for the holidays starting Dec. 24th and returning Jan. 11th.
We would like you to take the opportunity to refresh or spend time with your family, so Tesla will be giving you a full week pay for the week of Jan. 4th. There will also be limited paid opportunities for you to support other shops or volunteer for deliveries during some of this time.
Dec. 23rd – last day of work before shutdown
Dec. 24th-25th – Paid holidays*
Dec. 28th-30th – Unpaid time off (may use PTO**), support deliveries or other shops.
-->Dec. 31st-Jan. 1st – Paid Holiday*
Jan. 4th – 8th – Paid time off (40 hours)
Jan. 11th – return to work
If you would like to volunteer for deliveries for Dec. 26th — Dec. 31st, or support other shops from Dec. 28th – Dec. 30th, please use the survey below to let us know your preference. We will do our best to accommodate your requests, but preferences are not guaranteed and will be granted on a first come first serve basis.
While the shutdown of the Model S and Model X line this Q4 may be interpreted as a bearish sign of declining demand by Tesla critics, the production halt does give the company some time to update the vehicles’ manufacturing facilities. Tesla has kept silent about any upcoming improvements for the Model S and Model X, of course, but considering the company’s reputation and nature, it would not be surprising if it ends up using the 18-day shutdown to make sure that the two flagship vehicles will return better than ever.
-->In a separate email, Elon Musk emphasized that Tesla’s main issue today is demand. In true Tesla fashion, Musk also asked for any suggestions that would help the company improve its output further. Such improvements would go a long way in aiding Tesla this fourth quarter, seeing as the company would have to deliver about 180,000 vehicles before the end of the year to meet its half-a-million vehicle target for 2020.
Following is Musk’s email to Tesla employees about the matter.
Subject: Vehicle Production
We are fortunate to have the high class problem of demand being quite a bit higher than production this quarter.
To ensure that we have the best possible customer outcome and earn the trust of the customers and investors who have placed their faith and hard-earned money with us, we need to increase production for the remainder of the quarter as much as possible.
-->I would only send this note if it really mattered.
Super appreciated,
Elon
Btw, please send me a note directly if you see ways to improve output, but feel that your voice is not being heard.

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.
