Tesla teardown expert Sandy Munro recently recreated what he believes will be the new 4680 Battery Pack by recreating the cell housing unit for a new video. Munro is an extremely familiar figure to Tesla fans as he spent some time breaking down both the Model 3 sedan and, more recently, the Model Y crossover. However, the design expert, along with his team of highly-qualified engineers, composed a copy of the 4680 cell pack, which will be used in future Tesla models to increase power, energy, and range.
Munro admits that this may not be exactly what Tesla will use in its future vehicles, but this could likely be extremely similar to what the electric automaker will introduce. For those that aren’t familiar, the Model 3 and Model Y previously used Tesla’s 2170 cells, which were able to provide superior performance compared to the 18650 cells that were used in the Model S and Model X. However, the electric automaker had been working with Jeff Dahn and other researchers at Dalhousie University in Canada to develop new, revolutionary cells that would provide longer lifespans with more power and more energy.
Interestingly, these cells with higher performance would dramatically decrease Tesla’s cars’ cost, as the materials they used would be easier to obtain and cheaper to produce. Creating a more efficient and cost-effective battery cell was the main strategy in having Tesla’s vehicles comparable with gas cars in terms of cost.

Tesla uses 4,416 2170 cells in the Model Y, but this number is significantly lower with the 4680 cells due to their larger size, which carries significantly more energy and power than the previous cell. Munro states that only 960 cells will be used in the new battery pack, and with the increases in range, power, and energy, Tesla is truly onto something remarkable that will only increase their lead in the EV sector.
“We are focusing our attention on this, which is so much better than what they had with the 2170,” Munro said.
Tesla rolled out the new 4680 cell at its highly-anticipated Battery Day event on September 22nd. CEO Elon Musk summarized Tesla’s plan to begin building a more affordable battery cell, ultimately leading to a more affordable vehicle. In summation, Tesla plans to decrease the cost of cell manufacturing by a significant amount and decrease the cost of money per kilowatt-hour by up to 56% through design, production efficiencies, and material sourcing.
One of Tesla’s biggest advantages in designing its own cells and packs is that it can significantly reduce costs while also increasing the ability to fix issues when they occur. One of the strategies with its battery cells from the very beginning was to individualize each cell so it was easier be traced and replaced if any issues were to occur. Teslarati covered a recent replacement of a Model S battery cell showed the process for fixing a pack when a cell goes awry.
The new 4680 cells have been used for several months, Elon Musk said in an interview earlier this year. However, not all vehicles utilize the new cells as the Kato Road cell production facility near Tesla’s Fremont factory is not producing enough yet. However, the increased production will eventually lead to Tesla using the 4680 batteries exclusively within its cars, which will lead to higher range ratings and increased performance specs, making Tesla’s EVs even more superior to its competitors.
Munro’s full 4680 pack breakdown is available below.

Tesla owners surpass 8 billion miles driven on FSD Supervised
Tesla shared the milestone as adoption of the system accelerates across several markets.
Tesla owners have now driven more than 8 billion miles using Full Self-Driving Supervised, as per a new update from the electric vehicle maker’s official X account.
Tesla shared the milestone as adoption of the system accelerates across several markets.
“Tesla owners have now driven >8 billion miles on FSD Supervised,” the company wrote in its post on X. Tesla also included a graphic showing FSD Supervised’s miles driven before a collision, which far exceeds that of the United States average.
The growth curve of FSD Supervised’s cumulative miles over the past five years has been notable. As noted in data shared by Tesla watcher Sawyer Merritt, annual FSD (Supervised) miles have increased from roughly 6 million in 2021 to 80 million in 2022, 670 million in 2023, 2.25 billion in 2024, and 4.25 billion in 2025. In just the first 50 days of 2026, Tesla owners logged another 1 billion miles.
At the current pace, the fleet is trending towards hitting about 10 billion FSD Supervised miles this year. The increase has been driven by Tesla’s growing vehicle fleet, periodic free trials, and expanding Robotaxi operations, among others.
Tesla also recently updated the safety data for FSD Supervised on its website, covering North America across all road types over the latest 12-month period.
As per Tesla’s figures, vehicles operating with FSD Supervised engaged recorded one major collision every 5,300,676 miles. In comparison, Teslas driven manually with Active Safety systems recorded one major collision every 2,175,763 miles, while Teslas driven manually without Active Safety recorded one major collision every 855,132 miles. The U.S. average during the same period was one major collision every 660,164 miles.
During the measured period, Tesla reported 830 total major collisions with FSD (Supervised) engaged, compared to 16,131 collisions for Teslas driven manually with Active Safety and 250 collisions for Teslas driven manually without Active Safety. Total miles logged exceeded 4.39 billion miles for FSD (Supervised) during the same timeframe.

The Boring Company’s Music City Loop gains unanimous approval
After eight months of negotiations, MNAA board members voted unanimously on Feb. 18 to move forward with the project.
The Metro Nashville Airport Authority (MNAA) has approved a 40-year agreement with Elon Musk’s The Boring Company to build the Music City Loop, a tunnel system linking Nashville International Airport to downtown.
After eight months of negotiations, MNAA board members voted unanimously on Feb. 18 to move forward with the project. Under the terms, The Boring Company will pay the airport authority an annual $300,000 licensing fee for the use of roughly 933,000 square feet of airport property, with a 3% annual increase.
Over 40 years, that totals to approximately $34 million, with two optional five-year extensions that could extend the term to 50 years, as per a report from The Tennesean.
The Boring Company celebrated the Music City Loop’s approval in a post on its official X account. “The Metropolitan Nashville Airport Authority has unanimously (7-0) approved a Music City Loop connection/station. Thanks so much to @Fly_Nashville for the great partnership,” the tunneling startup wrote in its post.
Once operational, the Music City Loop is expected to generate a $5 fee per airport pickup and drop-off, similar to rideshare charges. Airport officials estimate more than $300 million in operational revenue over the agreement’s duration, though this projection is deemed conservative.
“This is a significant benefit to the airport authority because we’re receiving a new way for our passengers to arrive downtown at zero capital investment from us. We don’t have to fund the operations and maintenance of that. TBC, The Boring Co., will do that for us,” MNAA President and CEO Doug Kreulen said.
The project has drawn both backing and criticism. Business leaders cited economic benefits and improved mobility between downtown and the airport. “Hospitality isn’t just an amenity. It’s an economic engine,” Strategic Hospitality’s Max Goldberg said.
Opponents, including state lawmakers, raised questions about environmental impacts, worker safety, and long-term risks. Sen. Heidi Campbell said, “Safety depends on rules applied evenly without exception… You’re not just evaluating a tunnel. You’re evaluating a risk, structural risk, legal risk, reputational risk and financial risk.”

Tesla announces crazy new Full Self-Driving milestone
The number of miles traveled has contextual significance for two reasons: one being the milestone itself, and another being Tesla’s continuing progress toward 10 billion miles of training data to achieve what CEO Elon Musk says will be the threshold needed to achieve unsupervised self-driving.
Tesla has announced a crazy new Full Self-Driving milestone, as it has officially confirmed drivers have surpassed over 8 billion miles traveled using the Full Self-Driving (Supervised) suite for semi-autonomous travel.
The FSD (Supervised) suite is one of the most robust on the market, and is among the safest from a data perspective available to the public.
On Wednesday, Tesla confirmed in a post on X that it has officially surpassed the 8 billion-mile mark, just a few months after reaching 7 billion cumulative miles, which was announced on December 27, 2025.

The number of miles traveled has contextual significance for two reasons: one being the milestone itself, and another being Tesla’s continuing progress toward 10 billion miles of training data to achieve what CEO Elon Musk says will be the threshold needed to achieve unsupervised self-driving.
The milestone itself is significant, especially considering Tesla has continued to gain valuable data from every mile traveled. However, the pace at which it is gathering these miles is getting faster.
Secondly, in January, Musk said the company would need “roughly 10 billion miles of training data” to achieve safe and unsupervised self-driving. “Reality has a super long tail of complexity,” Musk said.
Training data primarily means the fleet’s accumulated real-world miles that Tesla uses to train and improve its end-to-end AI models. This data captures the “long tail” — extremely rare, complex, or unpredictable situations that simulations alone cannot fully replicate at scale.
This is not the same as the total miles driven on Full Self-Driving, which is the 8 billion miles milestone that is being celebrated here.
The FSD-supervised miles contribute heavily to the training data, but the 10 billion figure is an estimate of the cumulative real-world exposure needed overall to push the system to human-level reliability.
