Rumors have recently emerged from China suggesting that Tesla is looking to tap Switzerland’s Bühler as another Giga Press supplier. Similar to IDRA, Bühler is also a manufacturer of large-scale die-casting machines.
The rumor was initially shared by Tesla and EV industry watcher Chris Zheng on Twitter. Citing information from employees of a Chinese car startup, Zheng noted that China would have a number of vehicles in mass production next year that will be using integrated die castings like the Tesla Model Y. These companies reportedly benchmark and analyze Tesla and its vehicles.
“Tesla’s Giga press supplier will be replaced from Italy’s IDRA to Switzerland’s Bühler next year. The latter is also one of the world’s 6 largest die-casting giants. It rejected Tesla’s demand for a 6000t-level Giga press in 2019, but now their products offer better performance,” Zheng wrote on Twitter.
This is undoubtedly a rumor for now, though it is one that is extremely interesting. Teslarati has reached out to Tesla for a comment on the rumor and will update this story if or when we receive a response.
While the idea of IDRA being replaced by Bühler may sound too extreme, it is possible that Tesla would tap the resources of another die casting machine maker for its upcoming vehicle production ramp. Bühler is an interesting choice nonetheless, especially since the company was one of the firms that rejected Tesla’s proposal for a 6,000-ton Giga Press a few years ago.
Elon Musk himself mentioned this during the Cyber Rodeo event. According to Musk, Tesla had approach the world’s six top die-casting machine makers, and all but IDRA considered the construction of a Giga Press. Tesla has since proven that Giga Presses work, however, so it’s not surprising to see other companies also trying their hand at creating Giga Press-level machines.
“It’s a revolution in car manufacturing to basically make a car out of three major parts — a cast rear, a structural pack, and a cast front. So what you’re looking at are the biggest casting machines ever made. It’s kind of crazy thing to make a car this way. It’s never been done before.
“When we were trying to figure this out, there were six major casting manufacturers in the world. We called six. Five said’ no,’ one said ‘maybe.’ I was like ‘that sounds like a yes.’ So with a lot of effort and great ideas from the team, we’ve made the world’s biggest casting machine work very efficiently to create and radically simplify the manufacturing of the car,” Musk said.
A look at Bühler’s official website shows that the company is also developing giant die-casting machines that offer the highest productivity.
“Automotive manufacturers are currently rethinking production in many ways. Our Carat series enables them to put their ideas of even larger parts into reality, and we support our customers in developing the processes to do so. We see a huge increase in the demand for ever larger machines. With our Carat 840 and Carat 920 we can offer our customers solutions for large structural parts with complex geometries and new body-in-white parts,” Cornel Mendler, Managing Director of Bühler Die Casting, said.
Bühler’s Carat 840 and Carat 920 machines feature locking forces of up to 92,000 kilonewtons (kN). They are also designed to produce as little scrap as possible. “Bühler’s vision for the future of the die casting industry is: 0% scrap, 40% less cycle time, and 24/7 uptime. Advancing further towards this vision is even more important: The larger the castings, the bigger the lever to minimize production costs by reducing scrap, cycle time and increasing uptime of the die-casting system. The design of the Carat 840 and Carat 920 positively impact the quality of these complex, thin-walled parts which require an extremely powerful and accurate injection unit and a homogenous locking force application,” the company wrote in a press release.

GM CEO Mary Barra says she told Biden to give Tesla and Musk EV credit
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
General Motors CEO Mary Barra said in a new interview on Wednesday that she told President Joe Biden to credit Tesla and its CEO, Elon Musk, for the widespread electric vehicle transition.
She said she told Biden this after the former President credited her and GM for leading EV efforts in the United States.
During an interview at the New York Times Dealbook Summit with Andrew Ross Sorkin, Barra said she told Biden that crediting her was essentially a mistake, and that Musk and Tesla should have been explicitly mentioned (via Business Insider):
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
GM CEO Mary Barra said to Andrew Sorkin at the New York Times Dealbook Summit that she pulled President Biden aside and said Tesla CEO @elonmusk deserved the credit for EVs:

Back in 2021, President Biden visited GM’s “Factory Zero” plant in Detroit, which was the centerpiece of the company’s massive transition to EVs. The former President went on to discuss the EV industry, and claimed that GM and Barra were the true leaders who caused the change:
“In the auto industry, Detroit is leading the world in electric vehicles. You know how critical it is? Mary, I remember talking to you way back in January about the need for America to lead in electric vehicles. I can remember your dramatic announcement that by 2035, GM would be 100% electric. You changed the whole story, Mary. You did, Mary. You electrified the entire automotive industry. I’m serious. You led, and it matters.”
People were baffled by the President’s decision to highlight GM and Barra, and not Tesla and Musk, who truly started the transition to EVs. GM, Ford, and many other companies only followed in the footsteps of Tesla after it started to take market share from them.

Musk would eventually go on to talk about Biden’s words later on:
“They have so much power over the White House that they can exclude Tesla from an EV Summit. And, in case the first thing, in case that wasn’t enough, then you have President Biden with Mary Barra at a subsequent event, congratulating Mary for having led the EV revolution.”
In Q4 2021, which was shortly after Biden’s comments, Tesla delivered 300,000 EVs. GM delivered just 26.

Tesla Full Self-Driving shows confident navigation in heavy snow
So far, from what we’ve seen, snow has not been a huge issue for the most recent Full Self-Driving release. It seems to be acting confidently and handling even snow-covered roads with relative ease.
Tesla Full Self-Driving is getting its first taste of Winter weather for late 2025, as snow is starting to fall all across the United States.
The suite has been vastly improved after Tesla released v14 to many owners with capable hardware, and driving performance, along with overall behavior, has really been something to admire. This is by far the best version of FSD Tesla has ever released, and although there are a handful of regressions with each subsequent release, they are usually cleared up within a week or two.
Tesla is releasing a modified version of FSD v14 for Hardware 3 owners: here’s when
However, adverse weather conditions are something that Tesla will have to confront, as heavy rain, snow, and other interesting situations are bound to occur. In order for the vehicles to be fully autonomous, they will have to go through these scenarios safely and accurately.
One big issue I’ve had, especially in heavy rain, is that the camera vision might be obstructed, which will display messages that certain features’ performance might be degraded.
So far, from what we’ve seen, snow has not been a huge issue for the most recent Full Self-Driving release. It seems to be acting confidently and handling even snow-covered roads with relative ease:

I found the steepest, unplowed hill in my area and tested the following:
• FSD 14.2.1 on summer tires
• FSD 14.2.1 on winter tires
• Manual drivingBut I think the most impressive part was how FSD went DOWN the hill. FSD in the snow is sublime $TSLA pic.twitter.com/YMcN7Br3PU

Well.. I couldn’t let the boys have all the fun!
Threw the GoPro up and decided to FSD v14.2.1 in the snow. Roads were not compacted like the other day, a little slippery, but overall doable at lower speeds. Enjoy the video and holiday music 🎶

Moving into the winter months, it will be very interesting to see how FSD handles even more concerning conditions, especially with black ice, freezing rain and snow mix, and other things that happen during colder conditions.
We are excited to test it ourselves, but I am waiting for heavy snowfall to make it to Pennsylvania so I can truly push it to the limit.

Tesla hosts Rome Mayor for first Italian FSD Supervised road demo
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets.
Tesla definitely seems to be actively engaging European officials on FSD’s capabilities, with the company hosting Rome Mayor Roberto Gualtieri and Mobility Assessor Eugenio Patanè for a hands-on road demonstration.
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets. This comes amid Tesla’s push for FSD’s EU regulatory approvals in the coming year.
Rome officials experience FSD Supervised
Tesla conducted the demo using a Model 3 equipped with Full Self-Driving (Supervised), tackling typical Roman traffic including complex intersections, roundabouts, pedestrian crossings and mixed users like cars, bikes and scooters.
The system showcased AI-based assisted driving, prioritizing safety while maintaining flow. FSD also handled overtakes and lane decisions, though with constant driver supervision.
Investor Andrea Stroppa detailed the event on X, noting the system’s potential to reduce severe collision risks by up to seven times compared to traditional driving, based on Tesla’s data from billions of global fleet miles. The session highlighted FSD’s role as an assistance tool in its Supervised form, not a replacement, with the driver fully responsible at all times.
Path to European rollout
Tesla has logged over 1 million kilometers of testing across 17 European countries, including Italy, to refine FSD for local conditions. The fact that Rome officials personally tested FSD Supervised bodes well for the program’s approval, as it suggests that key individuals are closely watching Tesla’s efforts and innovations.
Assessor Patanè also highlighted the administration’s interest in technologies that boost road safety and urban travel quality, viewing them as aids for both private and public transport while respecting rules.
Replies on X urged involving Italy’s Transport Ministry to speed approvals, with one user noting, “Great idea to involve the mayor! It would be necessary to involve components of the Ministry of Transport and the government as soon as possible: it’s they who can accelerate the approval of FSD in Italy.”
