Tesla’s battery strategy will be key to Cybertruck and Semi’s market disruption
Elon Musk has remarked that Tesla has arguably the most exciting product roadmap of any company today. With vehicles like the Semi and the Cybertruck coming in the pipeline, this statement rings true. But things will not be as easy as simply setting up production lines for the upcoming vehicles. For Tesla to properly ramp the Semi, for example, the company would have to make sure that it can get enough cells for the vehicle first.
Producing electric cars is no easy task, and a lot of the challenges in EV making are connected in one way or another to vehicles’ batteries. This is something that is being learned by veteran carmakers like Jaguar today, as inadequate supply from battery companies like LG Chem has resulted in a halt of production for premium EVs like the I-PACE. Tesla is certainly aware of the battery supply challenges that EV makers face. This is one of the reasons why Gigafactory Nevada was constructed.
Giga Nevada was built to support the company’s Model 3 ramp. Designed to manufacture the 2170 cells of the Model 3 with battery partner Panasonic, the massive facility forms the backbone of Tesla’s first foray into the mass market. But the story lies far beyond the Model 3 today. Tesla has an even higher-volume vehicle coming, the Model Y. The Cybertruck will likely sell in large volumes too, provided that the market embraces it. Just like the all-electric pickup, the Semi might see sufficient demand from the trucking market once it’s released as well, considering the cost benefits that the vehicle offers.

Tesla is in a constant state of change, and this cannot be represented better than the company’s batteries. President of Automotive Jerome Guillen has noted that Tesla’s batteries are never static since they’re always being improved. Today, it is becoming more and more evident that Tesla’s batteries are among the best in the industry, particularly when it comes to energy density. Coupled with its vertically-integrated software, Tesla’s batteries can give vehicles impressive range even if they are not too large.
The Model 3, for example, can squeeze out over 320 miles of range from a 75 kWh battery, and the Model S Long Range Plus can get 390 miles from a 100 kWh pack. This matters a lot, and it shows just how far ahead the company is when it comes to its batteries and their energy density. And this, ultimately, will likely help the company secure enough battery cells to support the ramp of its upcoming EVs, including the Semi and the Cybertruck, both of which are large vehicles that would usually require a massive pack to hit their target range.
Tesla lists the Semi with a range of 300 to 500 miles. The company never announced the size of the Semi’s battery pack, but considering that the vehicle is a Class 8 truck that can accelerate from 0-60 mph in 20 seconds with a full load, speculations for the vehicle’s battery from the EV community included estimates that were as high as 1 MWh. The same concept applies to the Cybertruck. The vehicle is very heavy, and it is expected to have over 500 miles of range. To get this range, a large battery pack would usually be required.

But with Tesla’s constant innovations on its batteries, this does not necessarily have to be the case. Considering that Tesla is closing in on 400 miles per charge on a 100 kWh pack with the Model S, there is a good chance that its next vehicles like the Cybertruck and Semi will be equipped with fewer, but more energy-dense cells than initially expected. Tesla has pretty much developed the skill of drawing out as much range as possible from every cell in an EV, so it’s not too farfetched to infer that the company will be very efficient with the batteries of its upcoming vehicles.
More energy-dense batteries will be key to lowering production costs as well. Tesla may be drastically reducing its battery costs, but the packs themselves still comprise a huge portion of each of its vehicles’ prices. If Tesla can use slightly smaller packs that are still capable of providing optimum range, Tesla can make sure that its EVs like the Semi and the Cybertruck will be as competitive as possible when they enter the market.
The Tesla Semi and the Cybertruck are competing in the trucking and pickup market, two very lucrative segments in the automotive industry. Interestingly, both segments are also ripe for disruption, with most veterans such as Freightliner and the Ford F-150 sticking to tried and tested strategies to thrive today. Tesla needs a key to ensure that it can have a fighting chance when it enters the trucking and pickup segment with the Semi and Cybertruck. If challenges faced by electric car makers today are any indication, it appears that batteries and their energy density will be the difference-maker. Fortunately, these just happen to be two things that Tesla has been obsessively pursuing since the company was founded less than 17 years ago.

SpaceX set to launch astronauts and a classified Falcon Heavy mission on the same day
SpaceX plans three launches Thursday, including Crew-13 astronauts and Falcon Heavy’s first classified NRO mission.
SpaceX is lining up one of the busiest single days in its history, and the company offered a preview on Wednesday morning with a simple post on X: “Sunrise at pad 40.” The video and photos show Falcon 9 standing at Space Launch Complex 40 at Cape Canaveral, roughly a day before it is scheduled to carry four astronauts to the International Space Station.
That launch is only the first of three SpaceX missions planned for Thursday, October 1, across both coasts.

Crew-13 is targeting liftoff at 11:10 a.m. ET, with a backup opportunity Friday at 10:47 a.m. ET. NASA astronaut Jessica Watkins will command the mission, with NASA’s Luke Delaney as pilot and Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov serving as mission specialists. According to NASA, Dragon is set to dock with the forward port of the station’s Harmony module around 8 p.m. ET, less than nine hours after launch. Watkins is the only member of the crew who has flown before, and Kutryk will become the first Canadian to reach orbit through NASA’s Commercial Crew Program.
The Falcon 9 booster is flying for the third time after supporting Crew-12 and a Starlink mission, and it will attempt a landing at Landing Zone 40 beside the pad. That site made its debut in February when the Crew-12 booster touched down there, as Teslarati reported at the time. Crew-13 will relieve the Crew-12 astronauts, who have been aboard the station since the middle of February.
On the West Coast, another Falcon 9 is scheduled to lift off from Vandenberg Space Force Base in a window running from 2:18 to 3:16 p.m. ET, a flight NASASpaceflight lists as a Transporter rideshare mission.
The day is set to close at 11:53 p.m. ET, when Falcon Heavy launches from Launch Complex 39A with NROL-97, the first National Reconnaissance Office payload ever to fly on the rocket. SpaceX rolled the vehicle out to the pad Tuesday night. Its two side boosters, which previously flew GOES-U, ViaSat-3 F3 and NASA’s Roman Space Telescope, will return to Landing Zones 1 and 2, while a new center core will be expended in the Atlantic. The Roman launch took place on August 30, so NROL-97 will come barely a month later as Falcon Heavy’s third flight of 2026 and 14th overall.
NASA taps SpaceX to launch the telescope that could unlock new worlds
If all three Florida boosters land as planned, it would be the first time the Space Coast has seen landings at LZ-40, LZ-1 and LZ-2 on the same day, according to the Orlando Sentinel, which has warned residents in Brevard, Orange and Volusia counties that more than one sonic boom is possible.
The schedule arrives just three days after Starship reached orbit for the first time on Flight 14 from Starbase, Texas, deploying 26 Starlink V3 satellites. If Thursday’s missions stay on time, SpaceX will have flown Starship, Falcon 9 and Falcon Heavy from four different pads in about four days.
Crew-13 is also the start of a longer run for Dragon. NASA recently added Crew-15, Crew-16 and Crew-17 to SpaceX’s contract in a $946 million modification, keeping Dragon as the agency’s only operational ride to the station while Boeing’s Starliner remains grounded.

Tesla Cybercab and Semi have more in common than you might think
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.

Elon Musk weather update tips Tesla Roadster speculation into Plaid Mode
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.
