Tesla’s S3XY range updates show how ridiculously far legacy auto has fallen in the EV race
Anyone that has followed the Tesla story over the past few years would know that one of the primary talking points against the electric car maker is the impending competition that’s coming from more experienced, more competent carmakers. Critics argued that once legacy automakers get serious in their electric car efforts, a company as inexperienced as Tesla would easily be overwhelmed. This scenario has not happened at all — and if Tesla’s recent range updates to its S3XY lineup are anything to go by, it is becoming evident that legacy auto has fallen ridiculously behind in the electric car race.
Tesla’s recent range updates, which were rolled out together with the “refresh” of the Model 3, further cemented the company’s place at the top of the EV market. With the new updates, the Model 3 Long Range Dual Motor AWD was able to hit an EPA-estimated range of 353 miles per charge, and even its heftier, heavier sibling, the Model Y, was able to achieve a range of 326 miles. The Model X, an incredibly heavy tank of a vehicle, reached 371 miles per charge, and even the power-hungry Tesla Model S Performance is nearing 400 miles at 387 miles per charge.
It should be noted that Tesla was able to accomplish these improvements without any of the big updates that it announced during Battery Day. During the highly-anticipated event, Tesla revealed its batteries’ new 4680 form factor, which has 5x the volume of the Model 3 and Model Y’s 2170 cells. Tesla also announced a new vehicle manufacturing system that prioritizes single-piece casts and a structural battery pack. Other innovations, such as the use of high-nickel cathodes and silicon anodes, were discussed as well.
None of these innovations are in Tesla’s recently-updated vehicles.
Ultimately, Tesla’s recent updates highlight just how far the company has gone ahead of the pack in the electric vehicle sector. The fact that the electric car maker was able to achieve a 371-mile range for the Model X Long Range Dual Motor AWD with the same 100 kWh battery pack and the same 18650 cells as its Model X 100D predecessor is almost ridiculous. This is especially notable considering that the Audi e-tron, which has a battery pack that’s almost the same size as the Model X, has a range of 222 miles, and that’s the variant with the improved range already.
Tesla’s lead in range becomes even more significant when one considers the Model 3 and the Model Y, both of which utilize a battery pack that pretty much tops up at 75 kWh. A comparison of the two vehicles against the competition shows a stark contrast, with the Polestar 2, a car that’s largely considered as a legitimate rival to the Model 3, having an EPA-estimated range of 233 miles from a 78 kWh battery pack. The Jaguar I-PACE, a crossover that’s pretty close in size to the Model Y, follows the same pattern, having an EPA-estimated range of 246 miles per charge from a 90 kWh battery.
There are likely numerous reasons behind Tesla’s insane lead in the electric car sector today, but a good part of it likely has a lot to do with the company’s intense focus on battery tech and development. Tesla has been focused on improving and optimizing its batteries since Day 1, and as could be seen in the recent range updates of the S3XY lineup, this obsessive pursuit of optimization matters a lot. These efforts are not emulated at all with most legacy automakers, as veterans seem typically content with using off-the-shelf batteries from suppliers for their EV programs.
Yet perhaps the most uncomfortable reason behind legacy auto’s distance from Tesla’s vehicles today is something far simpler: hubris. While legacy automakers have been stating for years that they are serious about their future shift to electric cars, their actions have largely been far less tangible than their words. Today, it is almost as if Tesla’s competitors in the EV sector were far too comfortable just watching the electric car maker improve over the years. And now that Tesla has turned into a force that’s very difficult to ignore, they are scrambling to catch up.
Unfortunately, it is very difficult to catch a moving target. By the time legacy automakers can catch up to where Tesla is today, it is almost certain that the electric car maker will be even further ahead. This distance will likely be even farther, too, as Tesla’s next-generation battery technology is yet to enter the picture. Once Tesla’s 4680 cells are in production and its vehicles are being built with structural battery packs, the gap between the electric car maker and its competitors will most definitely be even more significant. And that, at least for legacy auto, is a scenario worthy of the final act of a tragedy.
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.

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.
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.
