No, Elon Musk did not “launch new attack” on General Motors (GM) or President Biden yesterday, as The Street recently reported. I thought I would clear this up here since it was my own tweet and Elon Musk’s response to my tweet might have somehow gotten misinterpreted.
According to the article, “Tesla’s CEO is resentful and never misses an opportunity to attack Detroit auto giant GM.”
The article also said that Elon Musk doesn’t want to promote the brands of his rivals and that GM is his favorite target. It, in my opinion, painted GM as the victim and Elon Musk as a bully. So I’d like to clear up some things and share what actually happened.
Elon Musk Didn’t “Launch New Attack” On Anyone
Yesterday, I shared a tweet by Sawyer Merrit with my own comment. I tagged both President Biden and Elon Musk. You can see the tweet below. This was and still is my opinion on GM’s decision to invest $1 billion into Mexico for an EV factory instead of investing those funds into American jobs.

As you can see for yourself, Elon Musk did not mention GM or President Biden. He mentioned Tesla and his reference was to Tesla being named the most American-made car by Cars.com.
GM’s Commitment To Mexico
I shared my thoughts about GM’s move to invest $1 billion in Mexico for an EV plant in this article. And there’s more. GM shared a statement on its Mexico media site where the company’s President and CEO, Francisco Garza said (translated by Google into English):
“We are very proud to contribute to the materialization of GM’s Vision of Zero Collisions, Zero Emissions, Zero Congestion, contributing to the manufacture of electric vehicles.”
“We trust that the necessary economic conditions will be met so that eventually the Complex can increase the workforce for one more shift in some operations. We are grateful to the Federal Government and the Government of Coahuila for promoting this investment. This is great news to continue celebrating GM’s more than 85 years in Mexico and show our commitment to the country.”
American Jobs Vs Mexican Jobs
It seems that my theory in the tweet that Elon Musk responded to could be correct. I saw this earlier this morning.:

@WholeMarsBlog shared screenshots of the salaries at the GM plant in Mexico where the new Chevy Blazer EV will be made. The starting pay for Operations is MX$91,950 per year which translates to $4,475.78 per year. There are other salaries with similarly low numbers.
In comparison, GlassDoor shows that technician salaries at GM average out at $63,166 annually. So, it seems that GM will be saving some serious money by outsourcing some of these jobs to Mexico.
My 2.5¢
Clearly, GM is trying to save money. And GM CEO, Mary Barra, recently expressed her confidence that GM can beat Tesla. You can draw your own conclusions from these two scenarios.
I do think that using Elon Musk to paint GM as a victim while downplaying its decision to make its Chevy Blazer EV in Mexico instead of the U.S. is really shady. And using my own tweet to do so as well. No, Elon Musk didn’t “launch new attack” on President Biden or GM. No one attacked them.
I just shared my own opinion on the matter and he pointed out which brand was the most American-made car.
Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.
The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.
🚨 Tesla designed the integrated thermal systems for Cybercab and Semi at the same time as the vehicles were both in development
Tesla wanted to build one thermal system that worked with both vehicles, apart from small modifications.

Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:
“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”
Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”
Priestley also highlighted a practical payoff of the indirect design:
“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”
This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.
The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.
This thermal system is also shared with Cybercab – one thermal system for both our most efficient vehicle & our biggest vehicle
— Tesla Semi (@tesla_semi) September 25, 2026
Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.
Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.
For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.
Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.
For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.
However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.
“Because this event can only be held outdoors…”
Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”
With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.
Roadster event update
We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

FAA Airspace Restriction
The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.
Tesla Roadster event requires restricted airspace, and the FAA obliges
Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.
Elon Admits High Winds
“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.
All signs are pointing toward an aerial demonstration for the Roadster.
Tesla has secured $30 billion in fresh credit lines from Citibank and Wells Fargo in an effort to scale its biggest current projects.
Tesla agreed to a $20 billion three-year delayed-draw term loan facility from Citibank, it announced on Tuesday. Additionally, it signed a five-year, $8 billion revolving credit facility and a $2 billion, 364-day term credit facility with Wells Fargo.
In a filing with the Securities and Exchange Commission (SEC), that it “may draw” from the $20 billion delayed-draw term “from time to time” and “no more than ten times during the 18 months following the closing date.” This loan matures on September 29, 2029.
The five-year revolving facility from Wells Fargo will also be accessed by Tesla “from time to time,” and will become due and payable on September 29, 2031. Tesla can request two separate one-year extensions.
On the $2 billion, 364-day revolving loan, it becomes due and payable on September 28, 2027. Tesla can also increase its additional commitments to an additional $4 billion across the Revolving Facilities. This would increase the total facilities to $14 billion. Tesla said it does not plan to utilize any of these loans in 2026.
Tesla plans to utilize the money to help prop up its ambitions to scale its biggest products, each of which is either in early launch phases or still in development. Of course, we’re talking about Cybercab and Semi, which have launched, and Optimus, which is still under heavy development and working toward initial release.
All three Tesla products have one thing in common: they’ve all required Tesla to build new manufacturing lines for them.
For the Semi, Tesla built a brand new factory in Sparks, Nevada, adjacent to the Tesla Gigafactory. For Optimus, Tesla sunset Model S and X production at the Fremont Factory, which brought an end to the two flagship models, thus creating manufacturing space for the humanoid robot. Finally, Cybercab is being built at Gigafactory Texas and officially entered production earlier this year.
The cash will help Tesla bolster its finances for the continuing development of these products. Tesla said that it forecasts its CapEx to be over $25 billion, up from just over $8.5 billion last year. These loans surely help with that spending.
