Tesla bull asks Elon Musk for Full Self-Driving value to be added with vehicle trade-in
Tesla will consider adding monetary value to its Full Self-Driving suite when an owner is attempting to trade-in their vehicle. The company is looking into the possibility following a request to Elon Musk from notable Wall Street analyst and Tesla bull Pierre Ferragu.
Ferragu, an analyst from New Street Research, currently owns a Model 3 equipped with Tesla’s Full Self-Driving suite. After purchasing the self-driving capability in November, Ferragu said he is interested in upgrading from a Model 3 to a Model Y. Still, he isn’t pleased about paying the $10,000 price tag for the semi-autonomous driving feature when he recently shelled out the money for the Model 3.
Tesla’s Full Self-Driving suite is what the company may be most known for outside of its highly-advanced electric vehicle tech, which has made it the undeniable leader in the EV sector. However, the Full Self-Driving suite is not included with the purchase of the vehicle like Basic Autopilot is, and to have the FSD capabilities, the owner must pay $10,000 on top of the price of the car.
“@elonmusk: I paid FSD for my Model 3 in November. I now want to upgrade to model Y and your team tells me you don’t value FSD in your trade-in offer because you can do the software upgrade for free. Want me to pay again full price for FSD again? That’s not fair, change that!” Ferragu tweeted to Musk.

Musk and Tesla are considering adding the transfer or giving some credit toward an FSD-equipped vehicle’s trade-in value. Currently, the issue is that Tesla is not giving any monetary value to the FSD suite when someone wishes to trade in their car toward a new one. This would effectively mean that FSD makes the car no more or less valuable than it would be without the functionality equipped. This is causing a dilemma with some owners who wish to upgrade or change their Tesla vehicle as it would require paying another hefty $10,000 fee.

Musk stated that he would look into the possibility of having FSD add value to a trade-in. The reason Tesla didn’t consider it before, according to Ferragu, is because the company can activate the functionality to any vehicle for free.
Looking into this. No question that FSD should be viewed as reasonably valuable when doing a trade-in.

Other owners would be interested in a one-time transfer to a new vehicle, which would be advantageous for multiple scenarios. One would be if a family has two Teslas, but one is driven more than another. If the new car will be driven more frequently, but the current car has FSD, some owners may want to transfer the self-driving capability to the new vehicle. Another situation that would give owners some more leeway would be if they are trading an FSD-equipped vehicle in for a new Tesla. If their FSD purchase was recent and at the same price point as the current $10,000 tag, the feature could be transferred to the new car. If the owner paid less, Tesla could require the owner to pay the difference.
Tesla has been known to listen to real-world owners and use the feedback to improve their cars. Musk will likely update the development as it is figured out. It will be interesting to see how the company values FSD through trade-ins or if it will take the route of a transfer option for recent buyers of the Full Self-Driving suite.
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’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 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.

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.

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.
