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.

Cantor Fitzgerald reaffirms bullish view on Tesla after record Q3 deliveries

The firm reiterated its Overweight rating and $355 price target.

Cantor Fitzgerald is maintaining its bullish outlook on Tesla (NASDAQ:TSLA) following the company’s record-breaking third quarter of 2025. 

The firm reiterated its Overweight rating and $355 price target, citing strong delivery results driven by a rush of consumer purchases ahead of the end of the federal tax credit on September 30.

On Tesla’s vehicle deliveries in Q3 2025

During the third quarter of 2025, Tesla delivered a total of 497,099 vehicles, significantly beating analyst expectations of 443,079 vehicles. As per Cantor Fitzgerald, this was likely affected by customers rushing at the end of Q3 to purchase an EV due to the end of the federal tax credit, as noted in an Investing.com report. 

“On 10/2, TSLA pre-announced that it delivered 497,099 vehicles in 3Q25 (its highest quarterly delivery in company history), significantly above Company consensus of 443,079, and above 384,122 in 2Q25. This was due primarily to a ‘push forward effect’ from consumers who rushed to purchase or lease EVs ahead of the $7,500 EV tax credit expiring on 9/30,” the firm wrote in its note.

A bright spot in Tesla Energy

Cantor Fitzgerald also highlighted that while Tesla’s full-year production and deliveries would likely fall short of 2024’s 1.8 million total, Tesla’s energy storage business remains a bright spot in the company’s results.

“Tesla also announced that it had deployed 12.5 GWh of energy storage products in 3Q25, its highest in company history vs. our estimate/Visible Alpha consensus of 11.5/10.9 GWh (and vs. ~6.9 GWh in 3Q24). Tesla’s Energy Storage has now deployed more products YTD than all of last year, which is encouraging. We expect Energy Storage revenue to surpass $12B this year, and to account for ~15% of total revenue,” the firm stated. 

Tesla’s strong Q3 results have helped lift its market capitalization to $1.47 trillion as of writing. The company also teased a new product reveal on X set for October 7, which the firm stated could serve as another near-term catalyst.

Tesla just got a weird price target boost from a notable bear

Tesla stock (NASDAQ: TSLA) just got a weird price target boost from a notable bear just a day after it announced its strongest quarter in terms of vehicle deliveries and energy deployments.

JPMorgan raised its price target on Tesla shares from $115 to $150. It maintained its ‘Underweight’ rating on the stock.

Despite Tesla reporting 497,099 deliveries, about 12 percent above the 443,000 anticipated from the consensus, JPMorgan is still skeptical that the company can keep up its momentum, stating most of its Q3 strength came from leaning on the removal of the $7,500 EV tax credit, which expired on September 30.

Tesla hits record vehicle deliveries and energy deployments in Q3 2025

The firm said Tesla benefited from a “temporary stronger-than-expected industry-wide pull-forward” as the tax credit expired. It is no secret that consumers flocked to the company this past quarter to take advantage of the credit.

The bump will need to be solidified as the start of a continuing trend of strong vehicle deliveries, the firm said in a note to investors. Analysts said that one quarter of strength was “too soon to declare Tesla as having sustainably returned to growth in its core business.”

JPMorgan does not anticipate Tesla having strong showings with vehicle deliveries after Q4.

There are two distinct things that stick out with this note: the first is the lack of recognition of other parts of Tesla’s business, and the confusion that surrounds future quarters.

JPMorgan did not identify Tesla’s strength in autonomy, energy storage, or robotics, with autonomy and robotics being the main focuses of the company’s future. Tesla’s Full Self-Driving and Robotaxi efforts are incredibly relevant and drive more impact moving forward than vehicle deliveries.

Additionally, the confusion surrounding future delivery numbers in quarters past Q3 is evident.

Will Tesla thrive without the EV tax credit? Five reasons why they might

Tesla will receive some assistance from deliveries of vehicles that will reach customers in Q4, but will still qualify for the credit under the IRS’s revised rules. It will also likely introduce an affordable model this quarter, which should have a drastic impact on deliveries depending on pricing.

Tesla shares are trading at $422.40 at 2:35 p.m. on the East Coast.

Benchmark has reiterated its “Buy” rating and $475 price target on Tesla stock (NASDAQ: TSLA) as the company prepares to report its third-quarter vehicle deliveries in the coming days. 

Tesla stock ended the third quarter at $444.72 per share, giving the EV maker a market cap of $1.479 trillion at the end of Q3 2025. 

Benchmark’s estimates

Benchmark analyst Mickey Legg noted that he expects Tesla’s deliveries to hit around 442,000 vehicles this Q3, which is under the 448,000-unit consensus but still well above the 384,000 vehicles that the company reported in Q2 2025. According to the analyst, some optimistic estimates for Tesla’s Q3 deliveries are as high as mid-460,000s.

“Tesla is expected to report 3Q25 global production and deliveries on Thursday. We model 442,000 deliveries versus ~448,000 for FactSet consensus with some high-side calls in the mid-460,000s. A solid sequential uptick off 2Q25’s ~384,000, a measured setup into year-end given a choppy incentive/pricing backdrop,” the analyst wrote.

Benchmark is not the only firm that holds an optimistic outlook on Tesla’s Q3 results. Deutsche Bank raised its own delivery forecast to 461,500, while Piper Sandler lifted its price target to $500 following a visit to China to assess market conditions. Cantor Fitzgerald also reiterated an “Overweight” rating and $355 price target for TSLA stock.

Stock momentum meets competitive headwinds

Tesla’s anticipated Q3 results are boosted in part by the impending expiration of the federal EV tax credit in the United States, which analysts believe has encouraged buyers to finalize vehicle purchases sooner, as noted in an Investing.com report.

Tesla shares have surged nearly 30% in September, raising expectations for a strong delivery report. Benchmark warned, however, that some volatility may emerge in the coming quarter.

“With the stock up sharply into the print (roughly ~28-32% in September), its positioning raises the bar for an upside surprise to translate into further near-term strength; we also see risk of volatility if regional mix or ASPs underwhelm. We continue to anticipate policy-driven choppiness after 3Q as certain EV incentives/credits tighten or roll off in select markets, potentially creating 4Q demand air pockets and order-book lumpiness,” the analyst wrote.
