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.
Tesla Cybercab is set to launch in Austin, Texas, on September 3, as the company has officially started sending out invitations to a dedicated event it will hold in the city where its headquarters is located.
The Cybercab is Tesla’s dedicated ride-sharing vehicle: it features just two seats and has no steering wheel or pedals. It is aimed at fully autonomous passenger transport, and will operate in the Robotaxi fleet alongside the Tesla Model Y, which has been performing driverless rides for real-world passengers for more than a year.

The launch of the Cybercab marks the next chapter in Tesla’s autonomy story. The company has been developing autonomous transport for years with its Full Self-Driving (Supervised) platform, which is available in any vehicle the company has built with the proper hardware and software capabilities.
Its capabilities vary by hardware and software version, but Tesla says its latest hardware version, known as AI4, can deliver full autonomy. However, future vehicles will operate with even more robust hardware packages, as Tesla will develop AI4.5 and AI5 for even more capability in its vehicles.
Following a report from The Information that surfaced earlier this week, the writing was on the wall that Tesla was set to launch Cybercab in the near term. The report stated Tesla could launch Cybercab as soon as the end of August. Tesla came close and has booked it for September 3.
The big thing with this event being scheduled is not necessarily that Tesla is launching a new vehicle, but instead that it is launching a vehicle that has no steering wheel or pedals and will operate exclusively on a self-driving program that is evidently nearing full autonomy. If the event allows vehicles to take passengers on public roads and drop them off wherever they please within the City of Austin, it will be a drastic advancement in the company’s self-driving story.
People have ridden in Cybercab previously: Tesla had the “We, Robot” event in October 2024, which allowed people to experience fully autonomous rides in a closed circuit at Warner Bros. Studios in Burbank.

Additionally, Tesla launched employee rides in Cybercab in July.
It’s a drastic step forward for Tesla, whose CEO, Elon Musk, has promised for years that the company would release a fully autonomous vehicle and platform capable of allowing drivers to relinquish any responsibility behind the wheel.
Elon Musk put a number on where he thinks SpaceX’s Starship program is headed by 2030, replying on X a day after President Trump signed a memo pushing the country toward 1,000 space launches and reentries a year.
The exchange started when Aaron Burnett, co-founder of propulsion startup Mach 33, posted that “1,000 launches/reentries is the goal,” quoting White House science adviser Michael Kratsios on the newly signed National Space Transportation Policy. Burnett noted that the FAA’s own bull-case forecast reached only 385 annual launches by 2030, while his firm’s conservative model already put SpaceX alone near 940. Musk responded, “We’re aiming to reach 30+ Starship launches/day in 2030, which is ~10k annualized. Still tiny numbers compared to airplane flights!”

That figure is specific to Starship, the rocket SpaceX is still developing for orbital and lunar missions, not the Falcon 9 fleet that carries most of the company’s current launch volume. Starship has flown twice this year, a slower pace than the four and five flights SpaceX managed in 2024 and 2025. Getting from two flights a year to 30 a day is the scale of jump the new federal policy is meant to clear regulatory room for.
Trump’s memo, signed Thursday, directs agencies to identify new launch and reentry sites on federal land, including a new reentry site within 90 days, and to speed up the permitting and environmental reviews that have long slowed cadence growth. It also sets a goal of returning American astronauts to the moon by 2028 and placing initial lunar base elements by 2030, tying the launch buildout directly to NASA’s Artemis program.
SpaceX has already been pushing the FAA toward higher numbers on its own. The agency approved up to 44 annual Starship launches from Kennedy Space Center in February, on top of a 2024 review that raised the cap at Starbase in Texas to 25 a year. Those approvals cover a fraction of the 10,000 annual flights Musk is now describing, which shows how far current permitting still sits from the administration’s stated target.
The near-term test of all this is more modest. SpaceX cleared a full-duration, six-engine static fire on its next Starship vehicle this week, the last major hardware checkpoint before Flight 14, which is targeting no earlier than August 28 and is expected to attempt the vehicle’s first full orbital mission. Musk said last week that a tower catch of the upper stage is still probably months away, a reminder that the immediate roadmap remains far more incremental than the daily launch numbers he just posted.
Tesla will resolve its massive recall of nearly three million vehicles in China with stickers and a software update.
On Friday, Chinese regulators filed recall plans against Tesla, Xiaomi, Leapmotor, Xpeng, Chery, Geely, Dongfeng, Arcfox, and FAW to resolve what is essentially a carbon-copy issue throughout each of the companies’ vehicle models: emergency door release latches are simply not visible enough.
Tesla door handle saga gets its latest chapter and a big change is coming
The companies will be required to add things that will make these latches, which will open the door in the event of an emergency, more visible. Of the 7 million vehicles impacted, Tesla accounts for 2,975,910 units. More than 1.9 million of those are Model Y vehicles, with the rest, just over 970,000, being Model 3s.
To resolve the issue, Tesla is going to add warning labels to the emergency latches free of charge, and then utilize an Over-the-Air update to add a post-crash window-lowering strategy, according to CNEVpost.
This massive effort to fix the all-electric Model Y and Model 3’s emergency latch system comes just months after several probes across various markets identified the trouble some had identifying this latch. Those who had gotten involved in car accidents that stripped the vehicle of its power were not aware that every Tesla has emergency door latches.
China’s State Administration for Market Regulation (SAMR) said that severe crashes that disable a vehicle’s low-voltage system could not only hinder occupants from getting out, but also make it more difficult for emergency response workers to gain entry.
SAMR is starting to tighten the regulations it has on door handles on vehicles. A new mandatory national standard will take effect for all models starting January 1, 2027, and will require all doors to be equipped with mechanical release mechanisms. This will effectively end purely electronic door handles. Models already on sale with type approval have been granted a two-year transition period, which will enable things to change until January 2029.
