Update: 5/3 12:40 pm est: Tesla has updated the specifications of the Model Y RWD in North America. See para. 3

A discrepancy in the Tesla Model Y’s specifications leaves experts and fans confused and wondering what will come to the United States.

Tesla has always been at least a little tight-lipped about its engineering and design, and this pseudo-secrecy certainly isn’t aided by its lack of a communications team. However, this has come to a head recently as fans have discovered a discrepancy in the specifications of Tesla’s newest offering, the rear-wheel-drive single-motor Model Y, which currently is only sold in select markets.

The Tesla Model Y spec discrepancy was first identified by Mathias Føns on Twitter, who pointed out that the Model Y RWD sold in North America is significantly heavier and charges substantially faster than its counterpart abroad.

Since its discovery, Tesla has updated its website, decreasing the weight listed in North America to match the global model. However, the Model Y RWD outside of North America still charges at 170kW, while its North American counterpart charges at 250kW. Tesla has not publically addressed this disparity.

Looking at the spec sheets posted on Tesla websites worldwide, the heavier and faster charging Model Y RWD is only being sold in North America, including both Canada and Mexico, though the vehicle is not yet available in the States. In contrast, models sold in Australia, Europe, and Asia are lighter and charge significantly slower. Specifically, the North American model is 389kg (857.6 lbs) heavier than its global counterpart and charges almost twice as fast, 250kW vs. 170kW. The listed weight of the model sold in China is 2kg heavier than the one sold in Europe, but it has the same recorded charging speed.

The two models also seem to differ slightly in estimated range, though they aren’t precisely comparable considering they use entirely different testing schedules; EPA in North America, WLTP in Europe and Australia, and CLTC in China.

Strangely, this discrepancy continues when comparing the Model Y RWD with the Model Y Long-Range AWD sold in the same market. According to the Tesla Canada website, the RWD is 319kg (703.3 lbs) heavier than the LR AWD, though they charge at the same speed, 250kW.

While some have hypothesized that this weight difference has to do with how the weight is measured in each country, the more likely difference, which could also explain the dramatic difference in charging speed, is battery chemistry. Tesla does not list this difference on its website. Still, using lithium iron phosphate (LFP) batteries in North America would explain the incredible weight difference and the charging speed increase, that is, if the global model is using a lithium nickel manganese cobalt (NMC) battery.

Tesla CEO Elon Musk has previously noted that the automaker plans to switch all of its lower-priced offerings to the cheaper-to-produce LFP battery, further adding credence to the battery chemistry hypothesis.

With Tesla expected to continue to grow the reach of each of its product lines, many anticipate it will only be a matter of time before the RWD variant of the Model Y makes its way to Tesla’s home market, the United States. And with the rest of North America already using the heavier, faster charging model, Americans should expect access to this variant instead of the global version.

Along with the charging speed bump, the LFP battery would provide significantly improved durability and battery lifespan compared to those sold in Europe, Asia, and Australia.

Reports from China have indicated that the Tesla Shanghai Megafactory has become a notable player in China’s booming battery export market.

Located in the Lingang New Area of the Shanghai Free Trade Zone, the Tesla Megafactory has been running at full throttle since opening in February. It produces Tesla Megapack batteries for domestic and international use.

As noted in a report from Sina Finance, the Tesla Shanghai Megafactory’s output of Megapack batteries helped drive a notable rise in lithium battery shipments from the city in the first three quarters of 2025. This is quite impressive as the Megafactory is a rather young facility, though it has been steadily increasing its production capacity.

“The establishment of this benchmark factory has not only driven the rapid development of Shanghai’s energy storage industry but also become a new growth engine for foreign trade exports. Driven by the Tesla energy storage factory’s opening, Shanghai’s lithium battery exports reached 32.15 billion yuan ($4.5 billion) in the first three quarters, a 20.7% increase,” the publication wrote.

Ultimately, the Shanghai Megafactory has proved helpful to the city’s “new three” industries, which are comprised of new energy vehicles, lithium batteries, and photovoltaic systems. Exports of the “new three” products reached 112.17 billion yuan ($15.7 billion), a 6.3% year-over-year increase during the same period. The city’s total trade volume grew 5.4% year-over-year as well, with exports up 11.3%, driven largely by the clean energy sector’s performance.

Energy storage is helping Shanghai

Since opening in February, the Shanghai Megafactory has been firing on all cylinders. In late July, Tesla Energy announced that the new battery factory has successfully produced its 1,000th Megapack unit. That’s quite impressive for a facility that, at the time, had only been operational for less than six months. 

Speed has always been a trademark of the Shanghai Megafactory. Similar to Tesla’s other key facilities in China, the Megafactory was constructed quickly. The facility started its construction on May 23, 2024. Less than a year later, the site officially started producing Megapack batteries. By late March 2025, Tesla China noted that it had shipped the first batch of Megapack batteries from the Shanghai plant to foreign markets.

“Take Back Tesla:” Unions and corporate watchdogs launch campaign against Musk’s 2025 pay package

A new shareholder campaign is calling for Tesla investors to vote against Elon Musk’s proposed 2025 CEO Performance Award.

A new shareholder campaign is calling for Tesla investors to vote against Elon Musk’s proposed 2025 CEO Performance Award, arguing it would deepen governance risks and weaken corporate accountability.

Ahead of Tesla’s Q3 2025 earnings report, a coalition of unions and watchdogs launched the “Take Back Tesla” initiative, urging investors to reject Musk’s pay proposal at next month’s annual meeting. The plan would grant the CEO additional shares worth nearly $1 trillion over ten years, expanding his ownership stake in the company to about 25%.

Unions and watchdogs argue that Elon Musk’s proposed plan rewards distraction

The Take Back Tesla campaign is backed by groups such as the American Federation of Teachers, Public Citizen, Americans for Financial Reform, Ekō, People’s Action, and Stop the Money Pipeline. 

As could be seen on the campaign’s website, the groups are arguing that Musk’s focus on political ventures and external businesses has distracted him from leading Tesla. The group’s website called Musk’s new CEO Performance Award “outrageous” as it involves an amount of wealth that is unreachable even by today’s top executives.

“In order to unlock the full amount of shares proposed in this compensation plan, Tesla’s value would need to increase dramatically to $8.5 trillion. As Tesla’s proxy statement points out, that would make Tesla roughly 2x as valuable as the most valuable company in the world (Nvidia) today. Arguably, growing Tesla’s value to double the value of Nvidia would justify paying Musk something like double the compensation of Nvidia’s CEO.

“But the annual value of Musk’s trillion dollar pay package isn’t just 2 times what Nvidia’s CEO made last year (just under $50 million); it’s more than 2,000 times what Nvidia’s CEO made last year. At his current compensation of $49.9 million, it would take Nvidia’s CEO over 2,000 years to earn the amount that Elon Musk could earn, on average, per year for the next ten years,” the group argued.

Board defends package as necessary, though some pushback is present

Tesla’s board insists the compensation plan is essential to retain Musk and sustain the company’s innovation in AI, robotics, and self-driving technology. The automaker noted that previous skepticism from proxy firms such as ISS and Glass Lewis preceded a 20x rise in Tesla’s market capitalization since 2018, a feat that seemed unrealistic when it was proposed.

As noted in a CNBC report, New York City Comptroller Brad Lander, who oversees a $300 billion pension fund, stated that while Tesla has been a great investment, he “vociferously opposes” Elon Musk’s proposed 2025 CEO Performance Award. 

“Most of the time we’ve held Tesla stock, it has been a solid investment, it’s grown over time, and that’s why we haven’t chosen to dump it, he said, adding that he views Tesla’s Board as “insufficiently independent” since they have allowed Musk to be “absentee CEO.” Landers also argued that Tesla as a whole has failed to hit its targets when it comes to its Robotaxi program and its Full Self-Driving technology.

For context, Elon Musk has maintained that his 2025 CEO Performance Award is not designed for him to gather even more wealth. Instead, he stressed that it is required so that he could take a controlling stake in the company.

Tesla Q3 2025 earnings: What analysts expect

The automaker delivered a record 497,099 vehicles and logged its highest-ever energy storage sales in Q3 2025.

Tesla’s (NASDAQ:TSLA) Q3 2025 earnings, which would be released after markets close today, could prove to be a test of confidence for the company’s shareholders. 

The automaker delivered a record 497,099 vehicles and logged its highest-ever energy storage sales, but analysts noted that these gains might have come at a cost. 

Record vehicle deliveries

Tesla’s profit per share is expected to fall about 25% year over year to around $0.53–$0.55, even as revenue rises from 4% to 6%, as noted in a report from Market Pulse. Analysts noted that Tesla’s record quarter was partly fueled by buyers rushing to complete purchases before the U.S. federal EV tax credit expired in September, a surge that could dampen Q4 demand. The company also dipped into its inventory to reach the record delivery number.

Analysts expect automotive gross margin (excluding regulatory credits) to land between a conservative 16.5% and 17%. This suggests that a good portion of Tesla’s Q3 delivery growth came from aggressive price cuts. If margins fall below 16.5%, it could hint at more cost pressures that the company would have to handle in the coming months.

Tesla’s Energy segment, meanwhile, is expected to act as a stabilizer. The business deployed 12.5 GWh of storage in Q3, driven by strong demand from AI data centers. Analysts expect this high-margin division to partially cushion the hit from the automaker’s thinner car profits.

AI, FSD, and Musk’s role

Tesla’s lofty valuation, trading about 17% above the average analyst consensus of $365, would likely depend heavily on investor belief in its AI and robotics initiatives. Industry watchers have stated that management must deliver credible updates on Full Self-Driving and the Robotaxi program to help justify the company’s current valuation.

Elon Musk’s proposed 2025 CEO Performance Award, which proxy advisors have urged shareholders to reject, would likely be discussed in the Q3 2025 earnings call has well. Musk has hinted that a failed vote could jeopardize Tesla’s AI strategy, making the company’s upcoming results quite crucial for market confidence.
