There is no doubt that the adoption of electric vehicles is already underway. Key auto markets such as China and Europe have adopted aggressive goals for a zero-emissions future, and electric cars continue to improve with every iteration. Yet, inasmuch as the EV segment has grown since the early days of the original Tesla Roadster, the evolution of electric cars is only just beginning. Over the years, there will be more breakthroughs for all-electric propulsion, and automakers that refuse to acknowledge this will probably find themselves in dire straits. 

These, as well as the upcoming EV technologies that are set to make a debut within the next few years, was the focus of an extensive interview with Sandy Munro and Mark Ellis from Munro and Associates. Conducted by Tesla owner-enthusiast Sean Mitchell of All Things EV, the interview touched on several topics, including the breakthroughs that will likely be seen in the Model Y crossover, the potential of Maxwell’s supercapacitors for electric vehicles, and what traditional automakers can do to be more competitive in the emerging EV market. 

Munro, who has extensive experience with the early-build Model 3 and several other vehicles like the BMW i3 and the Jaguar I-PACE, noted that the EV he is most excited about is the Model Y. Munro noted that the Y will be an interesting EV because it would likely show just how much Tesla learned from the Model 3 and its challenging ramp. The teardown expert also stated that he is immensely interested to see just what Tesla did to reduce the wiring of the Model Y to 100 meters from 1.5 km in the Model 3.

One thing that Munro and Ellis emphasized in the interview was that when it comes to electric cars, battery technology is key. Munro noted that at this point, any company that aims to push EV batteries further would best be advised to take on emerging technologies such as supercapacitors, which could have great implications for electric car technology. This is where Tesla’s acquisition of Maxwell Technologies could come into play. Maxwell, after all, is primarily noted for two of its innovations: dry electrode batteries and supercapacitors. 

Both of these have the potential to improve Tesla’s electric cars significantly. “The dry battery technology is game-changing if it comes to pass and they can put it in a car,” Ellis said while discussing Maxwell’s potential for Tesla. The veteran also provided a scenario where Maxwell’s supercapacitors could play a part in the operation of an EV. 

“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,” Ellis said.

As for the underwhelming range from competing EVs such as the Audi e-tron and the Jaguar I-PACE, Munro noted that this is simply because of their lack of vertical integration. “(It’s) because they’re buying them from somebody else,” the teardown expert mused. When asked if a good way for traditional automakers to be more competitive in the EV market is to start developing their own battery tech, Ellis warns that adopting such a strategy will likely take a long time. 

“That would be a 10-year project. There are going to be leaders in the battery industry, and a lot of the electric chemistries are under patent. They’re gonna have to be licensed. Whoever comes out on top is probably going to win. But just due to the sheer volume of batteries that are going to be needed in the next five years, you basically have three or four battery (cell) companies that are out there. You got Panasonic, you got Samsung, you got LG, and you’ve CATL from China. Those are the big four. Everybody else is going to find a niche in there,” Elli said.

With companies such as Tesla already making headway into the mass market with vehicles like the Model 3 and the upcoming Model Y, it would be easy to perceive the EV segment as having sufficiently matured. It should be noted that this is not the case, as EVs, including Tesla’s electric vehicles like the 370-mile Model S Long Range or the bang-for-the-buck Model 3 Standard Range Plus, still have far more to improve in the years to come. And it is exactly these improvements that make the electric car market just so compelling.

Elon Musk and Trump are closer than ever, and Tesla could be the big winner

Elon Musk sat beside Trump as AI leaders signed a voluntary White House safety accord.

Elon Musk had the seat right next to President Donald Trump on Tuesday as the White House hosted the leaders of America’s biggest artificial intelligence companies for a lunch that ended with a voluntary industry accord on AI safety.

A seating chart Trump posted on Truth Social placed Musk at the president’s left in the East Room, with Nvidia CEO Jensen Huang on his right, according to an Associated Press reporter. Anthropic CEO Dario Amodei, OpenAI President Greg Brockman, Meta’s Mark Zuckerberg, Google’s Sundar Pichai, Microsoft’s Satya Nadella and Amazon founder Jeff Bezos also attended, along with Vice President JD Vance and House Speaker Mike Johnson.

After the lunch, Trump told reporters outside the West Wing that the executives had signed “The White House Accord on Superintelligence: A Joint Commitment on Frontier SI Responsibilities.” Johnson described it as a voluntary statement of principles built on “robust internal controls and layers of internal and external review,” while Zuckerberg said company boards would independently review reports from outside auditors. Trump called the document “morally binding,” said he would name a new AI czar within days, and signed an executive order formally renaming artificial intelligence “super intelligence,” CNBC reported.

Musk was not in the room for Tesla alone. Since SpaceX absorbed xAI, he runs the company behind Grok and one of the largest AI training operations anywhere. On September 25, he said another 220,000 Nvidia GB300 chips would come online at Colossus 2 within a week, with more expected in November and December.

Musk also used the trip to restate his energy ambitions. “SpaceX is aiming together with Tesla to do 200 gigawatts of solar production per year,” he said at an event in Washington. It is the same combined target he laid out that feeds directly into Terafab, the Tesla and SpaceX chip venture that will need enormous amounts of power.

The showing between Musk and Trump has come a long way, since the two had the very public split in mid 2025 after Musk opposed the “Big Beautiful Bill” and left DOGE. They reconciled at Charlie Kirk’s memorial that September, and Trump later called their relationship “good”. Since then, Musk has joined Trump’s China delegation in May and attended last week’s White House state dinner for Chinese President Xi Jinping.

For Tesla, that access to government official could pay dividends. As Teslarati noted in January, federal autonomy rules, NHTSA oversight and a single national standard for driverless vehicles all run through an administration Musk can more easily reach directly as Tesla works to scale Robotaxi and Cybercab beyond Texas.

Tesla showrooms picked clean ahead of Q3 end as demand looks strong

Tesla (NASDAQ: TSLA) showrooms have been picked clean ahead of the end of the third quarter of the year, as demand looks to be strong and delivery estimates for new vehicles are pushed into late 2026 and early 2027.

Tesla appears to have sold out of many of its Model 3 and Model Y trim levels in the United States, as only the Model Y RWD and Model Y All-Wheel-Drive are available for delivery before the end of the year.

Additionally, many showrooms are either completely empty or void of all but just one demo unit within the buildings themselves in an effort to bolster what could be one of Tesla’s best quarters in vehicle deliveries in recent memory.

Additionally, when I spoke to the guys at Tesla Mechanicsburg two weeks ago, when I returned the Model Y L, their third hauler of the week had just arrived, and every vehicle on it, along with every vehicle in their delivery lot, was accounted for and had a name attached to it for delivery.

Tesla saw a 25 percent increase in deliveries in Q2 compared to the same quarter the year before. The vast majority of the 480,126 units it delivered, 467,762 vehicles to be exact, were the Model 3 and Model Y.

In Q3 2025, Tesla delivered 497,099 vehicles, once again a figure that was dominated by the company’s two mass-market vehicles. Analysts have unusually wide predictions for this quarter, likely because so many firms missed the Q2 delivery figure by such a substantial margin; Wall Street predicted 408,000 cars, while Tesla delivered 480,000.

Goldman Sachs has Tesla slotted for 435,000 deliveries in Q3, while JPMorgan said it anticipates 482,000. The median guess is about 449,000 deliveries for Q3.

SpaceX turned a heralding moment for Starship into its greatest

Starship reached orbit despite losing an engine, deployed 26 Starlink V3 satellites on Flight 14.

SpaceX’s Starship reached orbit for the first time on Monday, and for a few nail-biting minutes it looked like it wouldn’t. During ascent on Flight 14, one of Ship 41’s six Raptor engines shut down early, and SpaceX’s livestream host Dan Huot told viewers the team had decided not to commit to orbit. Minutes later, after what Huot described as a lot of conversation in the control room, the final poll came back in favor, and a roughly 19 second burn of a single Raptor pushed the ship into orbit about 170 miles up.

The reversal matters because SpaceX had written the exit ramp into the mission plan. The company said it would only fire the orbital insertion burn if flight controllers confirmed enough backup hardware remained for the deorbit burn, a condition Teslarati laid out ahead of the flight. Losing an engine was exactly the scenario that rule was built for.

Pressing forward fits Elon Musk’s history. Falcon 1 failed three straight times before its fourth launch reached orbit in 2008, with SpaceX nearly out of money, and Starship was developed by flying prototypes until they broke. What changed this year SpaceX going public, and with $SPCX sliding below its IPO price in July when Flight 13 slipped, the short interest climbed significantly, as Teslarati reported at the time. A Starship potentially lost today with revenue generating next-gen Starlink satellites aboard would have landed directly on shareholders.

That pressure showed up after orbit. SpaceX cut a flight planned to last nearly 10 hours to about three, moving splashdown from west of Chile to the North Pacific near Hawaii. SpaceX gave no reason, though Musk said this month the company was being extremely cautious about debris risk. The single Raptor for deorbit worked, and Ship 41 completed its flip and landing burn before breaking apart in the water, an outcome SpaceX expected. Musk has structured SpaceX’s governance to shield long term bets from market pressure.

The payload is the bigger business story. Musk posted that all 26 Starlink V3 satellites deployed and are “operating nominally.” Each V3 is rated for about 1 Tbps of downlink and 160 Gbps of uplink, so this single launch adds roughly 26 Tbps, about 10 times what a Falcon 9 load of V2 Mini satellites adds. The V3 is too large for Falcon 9, making Starship the only vehicle that can build out the planned 100,000 satellite constellation, at up to 60 per flight once it reaches routine service. Unlike the 20 V3 units on Flight 13, which reentered on a suborbital path, these will raise their orbits and could begin serving customers within weeks and bring in hundreds of millions of additional dollars in projected Starlink revenue.

SpaceX has already begun winding down Falcon 9 Starlink launches from Florida in favor of Starship. Reported targets put Flight 15 as early as October 19, leaving about three weeks to diagnose Monday’s engine shutdown before the next orbital attempt.
