Tesla is working on a new 110 kWh battery pack configuration that can stretch range well beyond 400 miles, according to a new discovery made in Tesla’s battery management system (BMS) firmware.

Jason Hughes, a notable Tesla owner and hacker who first uncovered the company’s plans for a “P100D” variant in 2016, found references to a larger battery pack capacity in the latest BMS firmware. “There is a packID that starts life set to ~109 kWh usable (400+ miles),” noted Hughes via Twitter, further suggesting that Tesla might be preparing for a battery pack as large as 115 kWh in capacity when factoring Tesla’s battery reserve.

Additionally, Hughes discovery points to a new battery pack configuration with 108 cells per group at ~450 volts per pack that could very well be a universal design to replace the aging Model S and Model X battery pack, while centralizing architecture for the Model 3 and upcoming Model Y.

Battery pack improvements don’t come as a surprise considering CEO Elon Musk disclosed during the Tesla Q4 2019 earnings call that the company is rapidly approaching a 400-mile range for the Model S. “It won’t be long before Model S has 400-mile range,” said Musk.

Just last week, Tesla Model S received a range boost from 370 miles to 390 miles of EPA-rated range, while the flagship Model X SUV saw an increase from 328 miles to 351 miles.

With confirmation from Tesla CEO Elon Musk that the next-generation Model S and Model X will utilize a larger capacity battery to support its new Plaid Powertrain, the latest leak by Hughes can be seen as further validation that new battery advancements will be announced soon.

A future battery pack upgrade can only help Tesla break the 400-mile barrier and widen the range gap with any would-be competition. Tesla ups the ante and solidifies its position as the leader of the pack in the electric vehicle industry with its focus on new battery advancements – something the community expects Elon Musk to present in its upcoming “Battery Day”.

A curious soul who keeps wondering how Elon Musk, Tesla, electric cars, and clean energy technologies will shape the future, or do we really need to escape to Mars.

Tesla Full Self-Driving pricing strategy eliminates one recurring complaint

Tesla’s new Full Self-Driving pricing strategy will eliminate one recurring complaint that many owners have had in the past: FSD transfers.

In the past, if a Tesla owner purchased the Full Self-Driving suite outright, the company did not allow them to transfer the purchase to a new vehicle, essentially requiring them to buy it all over again, which could obviously get pretty pricey.

This was until Q3 2023, when Tesla allowed a one-time amnesty to transfer Full Self-Driving to a new vehicle, and then again last year.

Tesla is now allowing it to happen again ahead of the February 14th deadline.

The program has given people the opportunity to upgrade to new vehicles with newer Hardware and AI versions, especially those with Hardware 3 who wish to transfer to AI4, without feeling the drastic cost impact of having to buy the $8,000 suite outright on several occasions.

Now, that issue will never be presented again.

Last night, Tesla CEO Elon Musk announced on X that the Full Self-Driving suite would only be available in a subscription platform, which is the other purchase option it currently offers for FSD use, priced at just $99 per month.

Tesla is shifting FSD to a subscription-only model, confirms Elon Musk

Having it available in a subscription-only platform boasts several advantages, including the potential for a tiered system that would potentially offer less expensive options, a pay-per-mile platform, and even coupling the program with other benefits, like Supercharging and vehicle protection programs.

While none of that is confirmed and is purely speculative, the one thing that does appear to be a major advantage is that this will completely eliminate any questions about transferring the Full Self-Driving suite to a new vehicle. This has been a particular point of contention for owners, and it is now completely eliminated, as everyone, apart from those who have purchased the suite on their current vehicle.

Now, everyone will pay month-to-month, and it could make things much easier for those who want to try the suite, justifying it from a financial perspective.

The important thing to note is that Tesla would benefit from a higher take rate, as more drivers using it would result in more data, which would help the company reach its recently-revealed 10 billion-mile threshold to reach an Unsupervised level. It does not cost Tesla anything to run FSD, only to develop it. If it could slice the price significantly, more people would buy it, and more data would be made available.

Tesla Model 3 and Model Y dominates U.S. EV market in 2025

The figures were detailed in Kelley Blue Book’s Q4 2025 U.S. Electric Vehicle Sales Report.

Tesla’s Model 3 and Model Y continued to overwhelmingly dominate the United States’ electric vehicle market in 2025. New sales data showed that Tesla’s two mass market cars maintained a commanding segment share, with the Model 3 posting year-to-date growth and the Model Y remaining resilient despite factory shutdowns tied to its refresh.

The figures were detailed in Kelley Blue Book’s Q4 2025 U.S. Electric Vehicle Sales Report.

Model 3 and Model Y are still dominant

According to the report, Tesla delivered an estimated 192,440 Model 3 sedans in the United States in 2025, representing a 1.3% year-to-date increase compared to 2024. The Model 3 alone accounted for 15.9% of all U.S. EV sales, making it one of the highest-volume electric vehicles in the country.

The Model Y was even more dominant. U.S. deliveries of the all-electric crossover reached 357,528 units in 2025, a 4.0% year-to-date decline from the prior year. It should be noted, however, that the drop came during a year that included production shutdowns at Tesla’s Fremont Factory and Gigafactory Texas as the company transitioned to the new Model Y. Even with those disruptions, the Model Y captured an overwhelming 39.5% share of the market, far surpassing any single competitor.

Combined, the Model 3 and Model Y represented more than half of all EVs sold in the United States during 2025, highlighting Tesla’s iron grip on the country’s mass-market EV segment.

Tesla’s challenges in 2025

Tesla’s sustained performance came amid a year of elevated public and political controversy surrounding Elon Musk, whose political activities in the first half of the year ended up fueling a narrative that the CEO’s actions are damaging the automaker’s consumer appeal. However, U.S. sales data suggest that demand for Tesla’s core vehicles has remained remarkably resilient.

Based on Kelley Blue Book’s Q4 2025 U.S. Electric Vehicle Sales Report, Tesla’s most expensive offerings such as the Tesla Cybertruck, Model S, and Model X, all saw steep declines in 2025. This suggests that mainstream EV buyers might have had a price issue with Tesla’s more expensive offerings, not an Elon Musk issue. 

Ultimately, despite broader EV market softness, with total U.S. EV sales slipping about 2% year-to-date, Tesla still accounted for 58.9% of all EV deliveries in 2025, according to the report. This means that out of every ten EVs sold in the United States in 2025, more than half of them were Teslas.

Tesla won dual categories in the Euro NCAP Best in Class awards, with the Model 3 being named the safest Large Family Car and the Model Y being recognized as the safest Small SUV.

The feat was highlighted by Tesla Europe & Middle East in a post on its official account on social media platform X.

Model 3 and Model Y lead their respective segments

As per a press release from the Euro NCAP, the organization’s Best in Class designation is based on a weighted assessment of four key areas: Adult Occupant, Child Occupant, Vulnerable Road User, and Safety Assist. Only vehicles that achieved a 5-star Euro NCAP rating and were evaluated with standard safety equipment are eligible for the award.

Euro NCAP noted that the updated Tesla Model 3 performed particularly well in Child Occupant protection, while its Safety Assist score reflected Tesla’s ongoing improvements to driver-assistance systems. The Model Y similarly stood out in Child Occupant protection and Safety Assist, reinforcing Tesla’s dual-category win. 

“The company’s best-selling Model Y proved the gold standard for small SUVs,” Euro NCAP noted.

Euro NCAP leadership shares insights

Euro NCAP Secretary General Dr. Michiel van Ratingen said the organization’s Best in Class awards are designed to help consumers identify the safest vehicles over the past year.

Van Ratingen noted that 2025 was Euro NCAP’s busiest year to date, with more vehicles tested than ever before, amid a growing variety of electric cars and increasingly sophisticated safety systems. While the Mercedes-Benz CLA ultimately earned the title of Best Performer of 2025, he emphasized that Tesla finished only fractionally behind in the overall rankings.

“It was a close-run competition,” van Ratingen said. “Tesla was only fractionally behind, and new entrants like firefly and Leapmotor show how global competition continues to grow, which can only be a good thing for consumers who value safety as much as style, practicality, driving performance, and running costs from their next car.”
