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.

Tesla Board Chair defends Elon Musk’s pay plan, slams proxy advisors

The letter comes ahead of Tesla’s 2025 Annual Meeting, where shareholders will vote on several key proposals.

Tesla Chair Robyn Denholm has issued a strongly worded letter urging investors to reject the latest recommendations from proxy advisory firms ISS and Glass Lewis, saying their “one-size-fits-all” approach fails to recognize Tesla’s unique business model and track record. 

The letter comes ahead of Tesla’s 2025 Annual Meeting, where shareholders will vote on several key proposals including Elon Musk’s 2025 CEO Performance Award and director reelections.

Tesla slams proxy advisors’ models

Denholm criticized both firms for consistently opposing Tesla’s growth-oriented plans, noting that the company’s market capitalization has increased twentyfold since shareholders approved Musk’s 2018 performance package, which both advisors had opposed at the time. 

“Our shareholders have ignored their recommendations, and it’s a good thing they did,” she wrote. “Otherwise, you may have missed out on our market capitalization soaring 20x while the proxy advisors time and time again recommended “against” Tesla proposals designed to promote the sort of extraordinary growth we have enjoyed.”

The letter argued that Glass Lewis and ISS use robotic policies that don’t account for Tesla’s innovation-driven structure. Tesla’s leadership maintained that the 2025 CEO Performance Award will only reward Musk if he achieves extraordinary market capitalization and operational goals. The plan, Denholm stated, aligns Musk’s incentives with long-term shareholder interests.

Tesla defends board leadership

Denholm also defended directors Ira Ehrenpreis and Kathleen Wilson-Thompson, calling them pivotal to Tesla’s governance and innovation strategy. She said both have driven Tesla’s growth and helped design compensation systems vital to competing in the AI and robotics talent race.

She warned that following ISS and Glass Lewis could turn Tesla into “just another car company,” and urged shareholders to “vote yes to robots, and reject robotic voting.” The letter also highlighted that neither ISS nor Glass Lewis owns Tesla stock, emphasizing that only shareholders “who have made an actual financial investment” should decide the company’s direction.

“If you prefer that Tesla turn into just another car company mired in the ways of the past, then you should follow ISS and Glass Lewis. If you believe that Tesla, under the visionary leadership of Elon and the oversight of a Board that includes business leaders with integrity like Ira, Kathleen and Joe, then you should vote with Tesla,” Denholm wrote.

Tesla analyst says this common earnings narrative is losing importance

“Numbers are going down next year, but that’s ok because it’s all about autonomy.”

A Tesla (NASDAQ: TSLA) analyst is doubling down on the idea that one common earnings narrative is losing importance as the company continues to work toward new technologies and projects.

This week, Tesla will report earnings for the third quarter, and one thing people always pay attention to is deliveries. Although Tesla reveals its deliveries for the quarter well before it reports earnings, many investors will look for commentary regarding the company’s strategy for responding to the loss of the $7,500 tax credit.

Tesla has made a few moves already, including a lease deal that takes a substantial amount of money off, launching new Standard models, and cutting up to 23 percent off of lease pricing.

Tesla makes crazy move to spur short-term demand in the U.S.

However, analysts are looking at the company in a different light.

Aligning with the narrative that Tesla is not just a car company and has many different projects, Gene Munster of Deepwater Asset Management believes many investors need to look at another part of the business.

Munster said the delivery figures for Q3, which landed at 497,099, the highest in company history, were padded by customers rushing to showrooms to take advantage of the expiring tax credit.

He believes that deliveries will be more realistic in subsequent quarters, but investors should not worry because the focus on Tesla is not going to be on how many cars it hands over to customers:

“Numbers are going down next year, but that’s ok because it’s all about autonomy.”

Tesla has been working nonstop to roll out a dedicated Robotaxi platform in various cities across the United States, and has already launched in two states: Texas and California.

It has also received regulatory approvals to test driverless Robotaxis in Arizona and Nevada, while seeking permissions in Florida and other states, according to the company’s online job postings.

Munster continued:

“Most people are hyper-focused on the Robotaxi opportunity and not focused as much on FSD.”

While Robotaxi is incredibly important, Tesla’s Full Self-Driving (Supervised) suite is also extremely crucial moving forward, as it sets the stage for the company to roll out a formidable self-driving service.

Tesla rolled out its newest FSD software to more owners last night, and as it expands, the company is gaining valuable data to refine its performance.

Earnings will be reported tomorrow at market close.

Tesla CEO Elon Musk’s $1 trillion pay package hits first adversity from proxy firm

ISS said the size of the pay package will enable Musk to have access to “extraordinarily high pay opportunities over the next ten years,” and it will have an impact on future packages because it will “reduce the board’s ability to meaningfully adjust future pay levels.”

Tesla CEO Elon Musk’s $1 trillion pay package, which was proposed by the company last month, has hit its first bit of adversity from proxy advisory firm Institutional Shareholder Services (ISS).

Musk has called the firm “ISIS,” a play on its name relating it to the terrorist organization, in the past.

The pay package aims to lock in Musk to the CEO role at Tesla for the next decade, as it will only be paid in full if he is able to unlock each tranche based on company growth, which will reward shareholders.

However, the sum is incredibly large and would give Musk the ability to become the first trillionaire in history, based on his holdings. This is precisely why ISS is advising shareholders to vote against the pay plan.

The group said that Musk’s pay package will lock him in, which is the goal of the Board, and it is especially important to do this because of his “track record and vision.”

However, it also said the size of the pay package will enable Musk to have access to “extraordinarily high pay opportunities over the next ten years,” and it will have an impact on future packages because it will “reduce the board’s ability to meaningfully adjust future pay levels.”

The release from ISS called the size of Musk’s pay package “astronomical” and said its design could continue to pay the CEO massive amounts of money for even partially achieving the goals. This could end up in potential dilution for existing investors.

If Musk were to reach all of the tranches, Tesla’s market cap could reach up to $8.5 trillion, which would make it the most valuable company in the world.

Tesla has made its own attempts to woo shareholders into voting for the pay package, which it feels is crucial not only for retaining Musk but also for continuing to create value for shareholders.

Musk has also said he would like to have more ownership control of Tesla, so he would not have as much of an issue with who he calls “activist shareholders.”
