Tesla’s 4680 battery cell program saw some notable milestones in the second quarter of 2024.

Tesla noted in its Q2 2024 Update Letter that it was able to produce 50% more 4680 cells in the second quarter compared to Q1 2024. The company also noted that in Q2, it was also able to successfully build the first validation Cybertruck equipped with in-house dry cathode 4680 cells. 

“In Q2, we produced over 50% more 4680 cells than in Q1 and continued to see cost improvements. In July, we entered validation of vehicle testing for our first prototype Cybertruck produced with in-house dry cathode 4680 cells – a major cost reduction milestone once ramped. Cost reduction across our product lineup remains a top priority,” Tesla wrote in its Q2 2024 Update Letter

Recent reports have suggested that Tesla is planning to mass produce and install 4680 cells with dry electrodes to consumer vehicles before the end of the year. Citing people reportedly familiar with the matter, Chinese publication LatePost noted that the 4680 cell’s complete iteration features negative and positive electrodes that are produced using Tesla’s in-house dry electrode process.

As per the publication, Tesla’s current 4680 cells reportedly feature a negative electrode that’s produced using the company’s dry electrode process, as well as a positive electrode that’s acquired from a supplier. Since the positive electrodes are sourced from a supplier, they are produced using conventional wet cathode processes.

If Tesla is able to successfully ramp the production of the 4680 cells’ complete iteration, the electric vehicle maker could see substantial cost savings for its vehicles. Tesla Vice President of Vehicle Engineering Lars Moravy summarized the milestones of the 4680 program in the second quarter during the Q2 2024 earnings call

“4680 production ramped strongly in Q2, delivering 51% more sales than Q1, while reducing COGS significantly. We currently produce more than 1,400 Cybertrucks of 4680 cells a week. We’ll continue to ramp upward as we drive cost down further toward the cost parity target we set for the end of the year. 

“We’ve built our first validation Cybertruck with dry cathode process made on mass production equipment, which is a huge technical milestone, and we’re super proud of that. We’re on track for production launch with the dry cathode in Q4. And this will enable cell costs to be significantly below available alternatives which was the original goal of the 4680 program,” Moravy said.

Tesla revises FSD transfer policy on new Cybertruck trim, causing cancellations

Published

Tesla has apparently revised the policy it previously had listed for Full Self-Driving transfers on the newest All-Wheel-Drive Cybertruck that the company had sold for a steal price of just $59,000 earlier this year.

After initially stating that customers who bought the pickup would be able to transfer FSD purchases, Tesla recently changed the language in those terms and conditions to reflect that this would no longer be the case.

Tesla launches new Cybertruck trim with more features than ever for a low price

The adjustment in terminology has caused a handful of orderers to cancel their reservations due to the loss of FSD transfer:

Tesla said orders for the new Cybertruck AWD must be placed by March 31, 2026, to qualify for the FSD transfer. The language in the document from earlier this year explicitly states that they “may qualify” for the transfer program, but the date of March 31 is explicitly mentioned.

Additionally, Tesla Delivery Advisors reached out to some orderers of the AWD Cybertruck, who were told there was “an update to the eligibility of the Full Self-Driving (Supervised) transfer.” Tesla stated they could:

  • proceed without the transfer,
  • upgrade to a Premium or Cyberbeast trim and request an FSD Transfer
  • cancel the order and be refunded the $250 order fee.

Tesla turning around and changing these terms will undoubtedly result in a handful of cancellations on the part of those who have placed an order for this truck. They could pay $99 per month for an FSD subscription, which is now the only option available, but having purchased the suite outright on another vehicle and being told the transfer policy would be upheld, only to have it cancelled, is a tough pill to swallow.

These moves were also made by Tesla just before deliveries were set to begin on the Cybertruck AWD configuration. Reservation holders have started receiving VINs for their trucks, and Tesla is preparing to hand over the first units.

It’s a disappointing move from Tesla that will undoubtedly make some of its fans who have bought the truck frustrated.

Tesla tipped its hand at where Robotaxi is heading next

In the world of autonomous ride-hailing, there are only a handful of names. Among those few companies lies a strategy play by each to keep the opposition on their toes. Tesla, on the other hand, already tipped its hand at where it is headed next.

Tesla has signaled its next major push in the autonomous ride-hailing market by filing for an Autonomous Vehicle Network Company permit in Nevada (Docket 26-05015). Through Tesla Robotaxi, LLC, the company seeks approval to operate up to 5,000 robotaxis in Clark County, including high-traffic areas like Las Vegas and Henderson airports, within the first 12 months of launch.

This filing builds on Tesla’s earlier testing approvals from the Nevada DMV in September 2025 and preparations such as maintenance hubs in the Las Vegas area. Nevada represents a strategic expansion into a major tourist destination, where high visitor volumes could drive strong utilization and showcase the reliability of unsupervised autonomy to a broad audience.

Approval would mark a significant step toward commercial operations in a new state, following progress in Texas.

Tesla’s shareholder decks and earnings calls have clearly outlined these ambitions. In the Q4 2025 shareholder deck, the company listed planned Robotaxi coverage for the first half of 2026, explicitly naming Las Vegas alongside Phoenix, Miami, Orlando, and Tampa, with Dallas and Houston already advancing. Austin was noted as “ramping unsupervised,” while the Bay Area remained in safety-driver mode.

By Q1 2026, the deck updated statuses to reflect launches in Dallas and Houston, with “preparations underway” for the remaining cities, including Las Vegas. Paid Robotaxi miles nearly doubled sequentially in Q1, underscoring momentum even as broader timelines adjusted slightly for regulatory and operational readiness.

On earnings calls, CEO Elon Musk and executives have emphasized a phased rollout prioritizing safety. Unsupervised operations in Texas have shown strong results with no reported accidents or injuries in the program. Tesla continues groundwork in additional major U.S. metros through testing and permitting, positioning it to scale quickly once approvals clear.

This Nevada move aligns with Tesla’s vision of transforming from an EV maker into an AI and robotics leader. The forthcoming Cybercab, which started production at Giga Texas in April, is expected to eventually dominate the fleet, replacing many Model Y vehicles and driving down costs to enable affordable rides.

For investors and the industry, this signals Tesla’s intent to dominate key Sun Belt and tourist markets where weather, regulations, and demand favor rapid scaling. Success in Las Vegas could validate the model for denser urban and high-tourism environments, accelerating the shift toward a future where robotaxis generate meaningful revenue.

Las Vegas will also expand knowledge among the general public at Tesla’s capabilities, helping people experience driverless ride-hailing from several companies during their time on The Strip.

Tesla just did something in South Korea that no foreign carmaker has ever done

Tesla’s Model Y just became South Korea’s best-selling car, beating every domestic model in May.

Tesla did something last month that no foreign car has ever done in South Korea by outselling every vehicle in the country, domestic or imported, finishing the month with Model Y as the single best-selling car across the entire Korean market. According to data from the Korea Automobile Importers and Distributors Association released on June 4, the Model Y recorded 8,762 units sold in May, pushing the Kia Sorento into second place at 7,836 units and the Hyundai Grandeur into third at 5,183 units. It is the first time an imported vehicle has outsold every domestic model on a single-month basis.

Tesla imported 10,866 cars into South Korea in May, making it the top import brand for the fourth consecutive month. BMW followed at 6,555 units, less than two-thirds of Tesla’s total, while BYD registered just 1,032 units. The combined domestic sales of GM Korea, Renault Korea, and KG Mobility last month totaled just 7,019 units, meaning a single Tesla model outsold three Korean automakers combined.

Tesla FSD earns high praise in South Korea’s real-world autonomous driving test

 

South Korea has historically been one of the hardest markets for foreign automakers to crack. Hyundai and Kia together control close to 70% of the overall market and carry deep consumer loyalty built over decades. Tesla’s path into this market was an uphill battle due to high import duties, limited service infrastructure, and early skepticism about charging networks. In 2024, the Model Y was the best-selling imported car in South Korea with 18,717 units for the full year. By 2025, after the Juniper refresh, it cleared 50,000 units and took the top spot among all EVs.

Year to date, Tesla has a 250.8% increase in the country over the same period last year, and now holds a 30.8% share of the entire imported car segment for 2026. EVs as a category represented 48.6% of all imported passenger car registrations in May. As Teslarati has reported, the Juniper refresh brought meaningful improvements to range, interior quality, and ride refinement that addressed the most common criticisms of earlier Model Y versions. Those upgrades appear to be resonating in markets like South Korea where buyers compare Tesla directly against high end domestic competitors.
