Tesla Model Y vehicles were spotted leaving Giga Texas on car carriers recently. The sighting hints that Tesla’s goal to deliver Giga Texas-made Model Ys to customers by the end of the first quarter is going according to plan.
At the last earnings call, Tesla announced that Giga Texas and Berlin production started in the previous quarter, Q4 2021. During his opening remarks, Tesla CEO Elon Musk confirmed that Austin-built Model Y vehicles are equipped with structural battery packs and 4680 cells. Tesla plans to deliver Giga Texas Model Ys once the vehicle receives final certification.
“So in Texas, we’re building the Model Ys with the structural battery pack and the 4680 cells, and we’ll start delivering after final certification of the vehicle, which should be fairly soon,” Musk said at Tesla’s Q4 and Full Year 2021 earnings call.
Drew Baglino, Tesla’s Senior Vice President of Powertrain and Energy Engineering, added that the company was making “meaningful progress of the ramp curve in Kato,” where Tesla is currently producing 4680 cells in a pilot line. He shared that Tesla was building 4680 structural battery packs every day and assembling them in Giga Texas vehicles.
“And we believe our first 4680 vehicles will be delivered this quarter,” Baglino stated. “Our focus on the cell, the pack, and the vehicles here is driving yield quality and cost to ensure we’re ready for larger volumes this year as we ramp and next year. And the 4680 and pack tool installations here at Giga Austin are progressing well, with some areas producing the first parts.”
The journey of Tesla’s 4680 cells has been long and filled with challenges, so seeing Model Y vehicles equipped with the batteries is exciting to those following its developments. Tesla unveiled its 4680 cells during Battery Day in September 2020. By Q2 2021, Tesla admitted to facing challenges with its 4680 pilot production line in Kato Road, mainly when it tried to transition from small-scale production to large volume production.
“Right now, we have a challenge with basically what’s called calendaring, or basically squashing the cathode material to a particular height,” Musk explained at the time. “So it just goes through these rollers and gets squashed like pizza dough, basically, but very hard pizza dough. And it’s causing — it’s denting the calendar rolls. This is not something that happened when the calendar rolls were smaller, but it is happening when the calendar rolls were bigger.”
However, Tesla seemed to have overcome most challenges with 4680 cell production. By August 2021, a Tesla investor claimed that the production yield of the 4680 cells rose to about 70%-80%, suggesting that the company was making progress in solving its calendaring issue. More recent reports hinted that the production yield of 4680 cells had been vastly improved since.

Elon Musk takes latest barb at Bill Gates over Tesla short position
Bill Gates placed a massive short bet against Tesla of ~1% of our total shares, which might have cost him over $10B by now
Elon Musk took his latest barb at former Microsoft CEO Bill Gates over his short position against the company, which the two have had some tensions over for a number of years.
Gates admitted to Musk several years ago through a text message that he still held a short position against his sustainable car and energy company. Ironically, Gates had contacted Musk to explore philanthropic opportunities.
Elon Musk explains Bill Gates beef: He ‘placed a massive bet on Tesla dying’
Musk said he could not take the request seriously, especially as Gates was hoping to make money on the downfall of the one company taking EVs seriously.
The Tesla frontman has continued to take shots at Gates over the years from time to time, but the latest comment came as Musk’s net worth swelled to over $600 billion. He became the first person ever to reach that threshold earlier this week, when Tesla shares increased due to Robotaxi testing without any occupants.
Musk refreshed everyone’s memory with the recent post, stating that if Gates still has his short position against Tesla, he would have lost over $10 billion by now:

Just a month ago, in mid-November, Musk issued his final warning to Gates over the short position, speculating whether the former Microsoft frontman had still held the bet against Tesla.
“If Gates hasn’t fully closed out the crazy short position he has held against Tesla for ~8 years, he had better do so soon,” Musk said. This came in response to The Gates Foundation dumping 65 percent of its Microsoft position.

Musk’s involvement in the U.S. government also drew criticism from Gates, as he said that the reductions proposed by DOGE against U.S.A.I.D. were “stunning” and could cause “millions of additional deaths of kids.”
“Gates is a huge liar,” Musk responded.
It is not known whether Gates still holds his Tesla short position.
Tesla made a change to the Cybertruck, and nobody noticed. But to be fair, nobody could have, but it was revealed by the program’s lead engineer that it was aimed toward simplifying manufacturing through a minor change in casting.
After the Cybertruck was given a Top Safety Pick+ award by the Insurance Institute for Highway Safety (IIHS), for its reputation as the safest pickup on the market, some wondered what had changed about the vehicle.
Tesla makes changes to its vehicles routinely through Over-the-Air software updates, but aesthetic changes are relatively rare. Vehicles go through refreshes every few years, as the Model 3 and Model Y did earlier this year. However, the Cybertruck is one of the vehicles that has not changed much since its launch in late 2023, but it has gone through some minor changes.
Most recently, Wes Morrill, the Cybertruck program’s Lead Engineer, stated that the company had made a minor change to the casting of the all-electric pickup for manufacturing purposes. This change took place in April:
We made a minor change on the casting for manufacturability in April. Our Internal testing shows no difference in crash result but IIHS only officially tested the latest version
— Wes (@wmorrill3) December 17, 2025
The change is among the most subtle that can be made, but it makes a massive difference in manufacturing efficiency, build quality, and scalability.
Morrill revealed Tesla’s internal testing showed no difference in crash testing results performed by the IIHS.
The 2025 Cybertruck received stellar ratings in each of the required testing scenarios and categories. The Top Safety Pick+ award is only given if it excels in rigorous crash tests. This requires ‘Good’ ratings in updated small and moderate overlap front, side, roof, and head restraints.
Additionally, it must have advanced front crash prevention in both day and night. Most importantly, the vehicle must have a ‘Good’ or ‘Acceptable’ headlights standard on all trims, with the “+ ” specifically demanding the toughest new updated moderate overlap test that checks rear-seat passenger protection alongside driver safety.
Tesla has entered an interesting situation with its Full Self-Driving suite in California, as the State’s Department of Motor Vehicles had adopted an order for a suspension of the company’s sales license, but it immediately put it on hold.
The company has been granted a reprieve as the DMV is giving Tesla an opportunity to “remedy the situation.” After the suspension was recommended for 30 days as a penalty, the DMV said it would give Tesla 90 days to allow the company to come into compliance.
The DMV is accusing Tesla of misleading consumers by using words like Autopilot and Full Self-Driving on its advanced driver assistance (ADAS) features.
The State’s DMV Director, Steve Gordon, said that he hoped “Tesla will find a way to get these misleading statements corrected.” However, Tesla responded to the story on Tuesday, stating that this was a “consumer protection” order for the company using the term Autopilot.
It said “not one single customer came forward to say there’s a problem.” It added that “sales in California will continue uninterrupted.”

Tesla has used the terms Autopilot and Full Self-Driving for years, but has added the term “(Supervised)” to the end of the FSD suite, hoping to remedy some of the potential issues that regulators in various areas might have with the labeling of the program.
It might not be too long before Tesla stops catching flak for using the Full Self-Driving name to describe its platform.

The Robotaxi suite has continued to improve, and this week, vehicles were spotted in Austin without any occupants. CEO Elon Musk would later confirm that Tesla had started testing driverless rides in Austin, hoping to launch rides without any supervision by the end of the year.
