How Tesla’s new Roadster can benefit from Maxwell’s supercapacitors
The new Tesla Roadster is the very definition of a halo car. Embodying all the innovations that Tesla has developed and mastered over the years, the next-gen Roadster is intended, as Elon Musk put it, to give a “hardcore smackdown” to gasoline cars. During the CEO’s appearance at the Ride the Lightning podcast, Musk even candidly mentioned that the upcoming vehicle will have capabilities that are practically “unfair” to its internal combustion-powered competition.
It has been almost two years since the vehicle was unveiled, and over this time, Tesla has made headway in its electric vehicle tech. Earlier this year, Tesla completed the acquisition of Maxwell Technologies, a company that specializes in supercapacitors and the development of dry battery electrode technology. These innovations, which Tesla has complete access to, are a perfect fit for the next-generation Roadster.
Munro and Associates Sr. Associate Mark Ellis recently noted during an interview with Tesla owner-enthusiast Sean Mitchell that Maxwell’s tech have immense potential in the electric vehicle segment. “The dry battery technology is game-changing if it comes to pass and they can put it in a car,” he said. Ellis also explained that supercapacitor technology could greatly help electric vehicles in terms of their battery management.
“One of the issues with the battery is, when I step on the throttle hard, I’m pulling a lot of energy from the battery. And then, when I brake hard, I’m pulling a lot of energy out of the regen, but the batteries can’t take it fast enough. The batteries get really stressed when you try to pull it up too much, so if I had supercapacitors that I could use as a cushion; so when I need energy quickly, (I can) pull it from the supercapacitors and then fill the supercapacitors back up with the battery slowly; and then when I brake, I can capture more of that regen energy and do the supercapacitors faster. I think that just makes logical sense, because now all of a sudden I’ve got a sponge in front of my main energy source and I’m not stressing (the battery) so much,” he said.
This “sponge” that Ellis mentioned will be greatly beneficial for vehicles like the next-generation Roadster, which is designed to accelerate at incredibly rapid speeds. The Roadster will be insanely quick on a straight line with its 0-60 mph time of 1.9 seconds, and based on Musk’s previous statements about the vehicle, the all-electric supercar will be able to take on track driving as well. This means that the next-generation Roadster will be a monster of a supercar, and it will require serious refinement in terms of its battery and electric motors to maintain its optimum performance.
Tesla is a far more experienced carmaker today than it was when Elon Musk unveiled the next-generation Roadster in 2017. Considering that Tesla is a company with a culture of innovation, it is almost certain that the new Roadster, once it is released, will be a far more refined vehicle than the already-game-changing supercar that shocked the auto industry nearly two years ago. Elon Musk, if any, has mentioned some of these updates, one of which is a SpaceX package that will utilize cold gas thrusters (the same technology used in SpaceX’s Falcon 9 rockets) to help the vehicle’s acceleration, braking, and maneuverability.
The impending arrival of the next-generation Roadster appears to have started a disruption in the hypercar market. Since the vehicle’s unveiling, other carmakers have introduced all-electric monsters of their own. Among these is the ~$2.5 million, 1,900 hp Pininfarina Battista, the ~$2 million, 1,973 hp Lotus Evija, and the $2.1 million, 1,914 hp Rimac C_Two. Considering that the Roadster will start at around $200,000, the vehicle will likely be closer in price to upcoming premium sports EVs like the Taycan Turbo S, which is expected to command a notably higher price compared to the ~$130,000 Taycan Turbo.
A Tesla upfitter has offered to take over Cybertruck lines from the company in a last-ditch effort to save the all-electric pickup from being completely canceled in the middle of 2027.
Unplugged Performance, the Hawthorne, California-based Tesla aftermarket specialist, has publicly offered to take over Cybertruck production from Tesla, funding the effort “through a consortium of investors.”
An open offer to Tesla: We fully support putting Cybercab first, and we’d be glad to take the Cybertruck line off your hands.
We’d fund it with a consortium of investors and run it at no cost to Tesla’s floor space, headcount, or focus. All of that goes to Cybercab. Cybercab gets first call on battery cells too. We’ll wait our turn.
Tesla gains incremental profit: a license fee, plus FSD and Robotaxi network revenues on every vehicle built.
We’d build the Cybertruck, a three-row CyberSUV, and an unmanned CyberCargo hauler. More autonomous miles, across every surface of this planet and beyond.
Worth a conversation?— UP (@UnpluggedTesla) November 10, 2026
The proposal comes as Tesla prioritizes its Cybercab Robotaxi program and prepares to wind down Cybertruck assembly at Gigafactory Texas around mid-2027.
Founded in 2013 by Ben Schaffer and located adjacent to Tesla’s Design Studio and SpaceX, Unplugged Performance has become a leading provider of premium upgrades for Tesla vehicles, including extensive Cybertruck packages under its UP INVINCIBLE line.
Through its UP.FIT division, the company has also developed purpose-built police and fleet versions of the Cybertruck, including deliveries to agencies such as the Las Vegas Metropolitan Police Department.
In an X post on Tuesday, Unplugged said:

The arrangement would free Tesla resources and manufacturing capacity for Cybercab while allowing continued production of the stainless-steel pickup and expanded variants. Unplugged Performance indicated it would wait for battery cells after Cybercab needs are met and would generate ongoing revenue for Tesla through licensing and software/network services on the vehicles it produces.
Following strong initial interest, Unplugged Performance posted a follow-up inviting potential investors and strategic partners to email cyber@unpluggedperformance.com. The company clarified that the outreach is solely to gauge interest and does not constitute an offer to sell securities or acceptance of funds at this stage.
The proposal arrives shortly after Elon Musk indicated that Cybertruck production in Texas would be phased out by roughly the middle of 2027 to expand Cybercab output.
Whether Tesla engages with the offer remains to be seen, but the public overture highlights both the aftermarket specialist’s deep experience with the Cybertruck platform and the growing focus on autonomy within Tesla’s manufacturing plans.
Elon Musk said the Tesla Cybercab will perform “a majority of all passenger miles” where it is allowed to operate and that point is “obvious to anyone with eyes and a brain.”
Musk used the point to double down on the company’s decision to ax the cult-favorite Cybertruck, as its production space will be removed and transitioned into additional Cybercab lines. The move has catalyzed a polarizing conversation on whether its right or wrong.
Whatever side you are on — it’s happening.
Dodge ended the Viper.
Audi retired the R8.
Mitsubishi said goodbye to the Lancer Evo.
Ford bid farewell to the Bronco (at one point).
Chevrolet sunset the Camaro.Tesla is ending the Cybertruck. I’m pissed. I’m upset.
Fans of those five automakers mentioned did the same thing. It happens. It sucks. I don’t like it.
But I still love Tesla. I love my Model Y. I hoped to be in a Cybertruck in a little under two years.
I won’t be. But I still won’t put my family in anything else. Too safe. Too advanced. Too much better than everything else.

Regardless, Musk seems to be getting to the point that he is done talking about the choice. At some point, you have to think that this was truly a difficult decision for him and the company as well, and this is not something he took lightly. In fact, he’s probably a little bit disappointed with it, too.
But the point remains that the Cybertruck is gone. Musk’s focus is purely on developing an autonomous platform that the world will utilize for transportation, and he’s telling you that anyone “with eyes and a brain” can see it:
@PalmerLuckey @carlhancock Cybercab will do a majority of all passenger miles in any jurisdiction where it is not prohibited by law.
Obvious to anyone with eyes and a brain.

Tesla is betting that all of its passengers in the future will be okay with not owning their own personal cars and will be fine with ride-hailing for the rest of their lives. Every dinner, every errand, every trip to the airport and transportation thereafter, will all be operated by ride-sharing, and in Tesla’s perfect world, it will happen in a Cybercab.
As of now, Cybercab is only active in Austin, but it has been spotted all over the country with a driver behind the wheel in those prototypes. In Austin, the car has no steering wheel or pedals for people to control the vehicle.
The Cybertruck dilemma is one that has truly come across the entire Tesla community and while it seems to be a great idea to keep it because people love it, the business side of things is steering Musk and Tesla in another direction.
Tesla has slimmed its Cybertruck offerings to offer only its most expensive trim: the Cyberbeast.
After announcing that the Cybertruck would no longer be produced and the company would wind down manufacturing sometime in the middle of 2027, Tesla started to eliminate some of the configurations offered to customers.
Tesla has stopped taking orders for the Cybertruck Premium AWD.
The Cyberbeast is now the only trim you can order, and its price went up $7,500 to $109,990.
Estimated deliveries have also slipped to March–June 2027 as the Giga Texas line heads toward its mid-2027 wind-down. https://t.co/o28epA0ZQl

Now, only one remains: the $109,990 Cyberbeast. This is truly what seems like Tesla’s last effort to deter any remaining orders from coming in: eliminate the cheap trims and leave only the high-dollar vehicle within the lineup of Cybertruck options.
Those who want to take advantage of this last-ditch opportunity to own Tesla’s symbolic pickup have to pay to play.
Tesla says the reason for the wind down is truly because of Cybercab and its importance to the future.
Despite cries for Tesla to continue production of the pickup, Musk says it is too difficult to ramp a high-volume line instead of ending the truck altogether. He also says Cybercab is what will take passengers around for the “majority of all miles in any jurisdiction where it is not prohibited by law.”

Tesla is going all in on autonomy, and that’s never been a secret. But the commitment to a two-door, two-seat Cybercab truly limits people from having options for labor or hobbies. It also limits people from having their entire family in a single car.
Parents with even a single child will be required to take multiple vehicles if Cybercab is truly the only option Tesla plans to have.
Elon Musk keeps justifying Tesla Cybertruck’s cancelation, but it’s confusing
Tesla has stated the Robovan will also be in production eventually, but it still does not seem like the most ideal vehicle to own. It seems like it is geared more toward commercial uses, but Tesla might have something in the pipeline for families.
