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 “best positioned” for Trump tariffs among automakers: analyst

Ives has a price target of $315 per share for the electric vehicle maker.

Wedbush analyst Dan Ives recently shared his thoughts about Tesla (NASDAQ:TSLA) amidst the Trump administration’s tariffs. As per Ives, Tesla is best-positioned relative to its rivals when it comes to the ongoing tariff issue.

Ives has a price target of $315 per share for the electric vehicle maker.

Best Positioned

During an interview with Yahoo Finance, the segment’s hosts asked about his thoughts on Tesla, especially considering Musk’s work with the Trump administration. Musk has previously stated that the effects of tariffs on Tesla are significant due to parts that are imported from abroad.

“When it comes to the tariff issue, they are actually best positioned relative to the Detroit Big Three and others and obviously foreign automakers. Still impacted, Musk has talked about that, in terms of just auto parts,” Ives stated.

China and Musk

Ives also stated that ultimately, a big factor for Tesla in the coming months may be the Chinese market’s reactions to its tariff war. He also noted that the next few quarters will be pivotal for Tesla considering the brand damage that Elon Musk has incited due to his politics and work with the Trump administration.

“When it comes to Tesla, I think the worry is where does retaliatory look like in China, in terms of buying domestic. I think that’s something that’s a play. And they have a pivotal six months head, in terms of what everything we see in Austin, autonomous, and the buildout. 

“But the brand issues that Musk self-inflicted is dealing with in terms of demand destruction in Europe and the US. And that’s why this is a key few quarters ahead for Tesla and also for Musk to make, in my opinion, the right decision to take a step back from the administration,” Ives noted.

Tesla negativity “priced into the stock at its current levels:” CFRA analyst

The CFRA analyst has given Tesla a price target of $360 per share.

In recent comments to the Schwab Network, CFRA analyst Garrett Nelson stated that a lot of the “negative sentiment towards Tesla (NASDAQ:TSLA) is priced into the stock at its current levels.”

The CFRA analyst has given Tesla a price target of $360 per share.

Q1 A Low Point in Sales

The CFRA analyst stated that Tesla’s auto sales likely bottomed last quarter, as noted in an Insider Monkey report. This was, Nelson noted, due to Q1 typically being the “weakest quarter for automakers.” He also highlighted that all four of Tesla’s vehicle factories across the globe were idled in the first quarter.

While Nelson highlighted the company’s changeover to the new Model Y as a factor in Q1, he also acknowledged the effects of CEO Elon Musk’s politics. The analyst noted that while Tesla lost customers due to Musk’s political opinions, the electric vehicle maker has also gained some new customers in the process.

CFRA’s Optimistic Stance

Nelson also highlighted that Tesla’s battery storage business has been growing steadily over the years, ending its second-best quarter in Q1 2025. The analyst noted that Tesla Energy has higher margins than the company’s electric vehicle business, and Tesla itself has a very strong balance sheet.

The CFRA analyst also predicted that Tesla could gain market share in the United States because it has less exposure to the Trump administration’s tariffs. Teslas are the most American-made vehicles in the country, so the Trump tariffs’ effects on the company will likely be less notable compared to other automakers that produce their cars abroad.

Tesla average transaction prices (ATP) rise in March 2025: Cox Automotive

Tesla Model Y and Model 3 saw an increase in their average transaction price (ATP) in March 2025.

Data recently released from Cox Automotive’s Kelley Blue Book has revealed that electric vehicles such as the Tesla Model Y and Model 3 saw an increase in their average transaction price (ATP) in March 2025.

Cox Automotive’s findings were shared in a press release

March 2025 EV ATPs

As noted by Cox, new electric vehicle prices in March were estimated to be $59,205, a 7% increase year-over-year. In February, new EV prices had an ATP of $57,015. The average transaction price for electric vehicles was 24.7% higher than the overall auto industry ATP of $47,462.

As per Cox, “Compared to the overall industry ATP ($47,462), EV ATPs in March were higher by nearly 25% as the gap between new ICE and new EV grows wider. EV incentives continued to range far above the industry average. In March, the average incentive package for an EV was 13.3% of ATP, down from the revised 14.3% in February.”

Tesla ATPs in Focus

While Tesla saw challenges in the first quarter due to its factories’ changeover to the new Model Y, the company’s ATPs last month were estimated at $54,582, a year-over-year increase of 3.5% and a month-over-month increase of 4.5%. A potential factor in this could be the rollout of the Tesla Model Y Launch Series, a fully loaded, limited-edition variant of the revamped all-electric crossover that costs just under $60,000.

This increase, Cox noted, was evident in Tesla’s two best-selling vehicles, the Model 3 sedan and the Model Y crossover, the best-selling car globally in 2023 and 2024. “ATPs for Tesla’s two core models – Model 3 and Model Y – were higher month over month and year over year in March,” Cox wrote.

Cox’s Other Findings

Beyond electric vehicles, Cox also estimated that new vehicle ATPs held steady month-over-month and year-over-year in March at $47,462, down slightly from the revised-lower ATP of $47,577 in February. Sales incentives in March were flat compared to February at 7% of ATP, though they are 5% higher than 2024, when incentives were equal to 6.7% of ATP. 

Estimates also suggest that new vehicle sales in March topped 1.59 million units, the best volume month in almost four years. This was likely due to consumers purchasing cars before the Trump administration’s tariffs took effect. As per Erin Keating, an executive analyst at Cox, all things are pointing to higher vehicle prices this summer. 

“All signs point to higher prices this summer, as existing ‘pre-tariff’ inventory is sold down to be eventually replaced with ‘tariffed’ inventory. How high prices rise for consumers is still very much to be determined, as each automaker will handle the price puzzle differently. Should the White House posture hold, our team is expecting new vehicles directly impacted by the 25% tariff to see price increases in the range of 10-15%,” Keating stated.
