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 counters Norway’s VAT hike with dedicated consumer bonus
The move follows Tesla Norway’s stunning finish in 2025, where the company saw substantial sales during the final weeks of the year.
Tesla has rolled out a price incentive in Norway, effectively offsetting a notable VAT increase that hit electric vehicle buyers at the start of 2026.
The move follows Tesla Norway’s stunning finish in 2025, where the company saw substantial sales during the final weeks of the year.
A “Tesla bonus”
Once the VAT increase kicked in at the start of 2026, Tesla Norway’s sales cooled almost immediately, as noted in a CarUp report. Tesla’s response was swift, with the electric vehicle maker rolling out what it calls a “Tesla bonus.”
This bonus effectively cuts prices by up to 50,000 kronor across eight model variants. All versions of the Tesla Model Y qualify for the incentive, along with most Tesla Model 3 trims, save for the base entry-level model.
This means that for Tesla Norway’s best-selling vehicles, the bonus effectively restores pricing to pre-VAT levels. This blunts the impact of the new tax and makes Tesla’s vehicle offerings competitive again in Europe’s most EV-saturated market.
Stabilizing demand
In addition to the “Tesla bonus,” the electric car maker is also offering a promotional interest rate for up to three years, with terms varying by model. The incentive applies to orders placed between January 9 and March 31, 2026, with delivery required by the end of the first quarter.
The stakes are high in Norway, where electric vehicles dominate new-car registrations. From the vehicles that were sold in 2025, 96% of new cars sold were fully electric. And from this number, Tesla and its Model Y made their dominance felt. This was highlighted by Geir Inge Stokke, director of OFV, who noted that Tesla was able to achieve its stellar results despite its small vehicle lineup.
“Taking almost 20% market share during a year with record-high new car sales is remarkable in itself. When a brand also achieves such volumes with so few models, it says a lot about both demand and Tesla’s impact on the Norwegian market,” Stokke stated.

SpaceX gains favor as Pentagon embraces Musk-style defense reform
The remarks highlighted Musk’s improving relationship with the White House, as well as SpaceX’s growing role in U.S. defense.
SpaceX emerged as a clear beneficiary of the Trump administration’s renewed push to accelerate military innovation, as Defense Secretary Pete Hegseth openly praised Elon Musk’s private space enterprise during a visit to the company’s Starbase launch site in Texas.
The remarks highlighted Musk’s improving relationship with the White House, as well as SpaceX’s growing role in U.S. defense.
Hegseth embraces Elon Musk’s pace
Speaking at SpaceX’s Starbase facility in Brownsville, Texas, Hegseth criticized what he described as a “risk-averse culture” among traditional defense contractors and called for faster innovation modeled after Musk’s approach. He confirmed that the Department of Defense plans to integrate Musk’s Grok AI platform into Pentagon systems, which is part of the administration’s efforts to make the U.S. military an “AI-first warfighting force.”
Hegseth stated that the Pentagon intends to deploy AI models across both classified and unclassified networks, signaling a willingness to push past earlier efforts to limit military use of artificial intelligence. His comments aligned closely with President Donald Trump’s recent call for a $500 billion increase in defense spending, Bloomberg News noted. Trump has also warned major contractors that slower production and shareholder-focused practices could put future contracts at risk.
While Hegseth criticized legacy defense firms, SpaceX was held up as an example of how aggressive timelines, vertical integration, and iterative development could reshape defense strategies. “We need to be blunt here; we can no longer afford to wait a decade for our legacy prime contractors to deliver a perfect system. Winning requires a new playbook. Elon wrote it with his algorithm: question every requirement, delete the dumb ones and accelerate like hell,” Hegseth said.
SpaceX’s expanding defense role comes into focus
SpaceX has become one of the U.S. government’s most important aerospace partners. The company holds roughly $4 billion in NASA contracts to develop Starship into a lunar lander, while also serving as a key launch provider for sensitive national security payloads using its Falcon 9 and Falcon Heavy rockets.
During the visit, Musk highlighted that his ambitions extend beyond defense contracts, reiterating long-term goals of interplanetary travel and eventual exploration beyond the solar system. Still, the optics of the event reinforced how closely SpaceX’s capabilities now align with U.S. strategic priorities.
The appearance also marked another step in Musk’s political rehabilitation after a public falling-out with the White House last year. Since leaving his role leading the Department of Government Efficiency, Musk has gradually reengaged with the administration, reconnecting with U.S. President Donald Trump during slain conservative activist Charlie Kirk’s tribute and attending events at the White House. Trump’s also recently suggested that Starlink could help restore internet access in Iran.
Tesla has launched a new Model Y configuration in the “Premium” trim, and it comes with three highly requested features that have launched in markets outside of the U.S. and in other trims.
Tesla announced on Monday night that it has officially launched the Model Y Premium in a seven-seat configuration, which also comes standard with a 16″ touchscreen and black headliner, both of which are featured in the Model Y Performance trim.
The seven-seat configuration is highly requested by consumers and helps fill out the more spacious SUV offering that the lineup has missed outside of the Model X, which prices out many consumers. This new upgrade only costs $2,500 extra for all three features, bringing the cash price to $48,990.

The move to add the seven-seat configuration with the black headliner and additional screen size is a welcome addition, as many Tesla fans have asked the company to come out with an SUV with more seating capacity. Although it is not a full-size SUV, the additional seating will certainly attract some buyers with bigger families.
It appears the third row is slightly more spacious than the past iteration of the seven-seat Model Y, which was available in the previous design pre-Juniper:

However, it definitely still appears to be pretty cramped in terms of legroom. It will definitely be a seating arrangement for smaller passengers, mostly reserved for children.
The other two upgrades are the black headliner, which was launched in other markets and in the Model Y Performance. Many owners have wanted this change, and Tesla listened, but is only offering it with the seven-seat configuration. It also has a larger 16″ touchscreen, also present in the Model Y Performance exclusively:

It is a nice touch to add these highly requested features to the all-electric crossover, which was the best-selling vehicle in the world for the third consecutive year.
