A picture of the Tesla Model S Plaid’s 18650 battery pack with its modules visible was recently shared online. The image hinted that Tesla is still in the process of optimizing and innovating its 18650 battery technology, despite the cells being quite a bit long in the tooth.

Tesla is constantly trying to improve its battery technology, which has led to the development of the company’s highly-anticipated 4680 cells. The 4680 cells are expected to be used in vehicles that require a lot of power such as the Semi, Cybertruck, and new Roadster. Amidst the ongoing supply chain challenges and delays in the mass production of 4680 cells from Tesla’s Kato Road facility, however, the company noted that the Model S Plaid, its current flagship sedan, will maintain its use of 18650 batteries.

According to Redditor u/punx, who posted the picture, the Model S Plaid’s battery pack features five large modules, packed to the brim with Panasonic’s 18650 cells. The Reddit user confirmed the cells were 18650 with measurements proving they were 18mm in diameter and 65mm in length. Previous iterations of the Model S have battery packs with as many as 16 individual modules.

A decrease in the number of modules in the Model S Plaid’s battery means fewer parts for the vehicle’s pack, resulting in lower production costs for Tesla. Lowering production costs for its vehicles is a key priority for the company. At the 2021 Annual Shareholders Meeting, Elon Musk mentioned that Tesla has been making a lot of progress in cost reduction, despite the average selling price going down due to the lower prices of vehicles like the Model 3 and Model Y.

“We managed to still do decently well on a gross margin. So, you know, getting the average price down and gross margin up is very difficult,” Musk pointed out. “But we’ve managed to do that. Our goal is really to make the cars as affordable as possible.”

The Model S Plaid (and perhaps the Model X Plaid) might be the last vehicles in Tesla’s lineup that would use 18650 cells. With Tesla focusing its efforts to master the mass production of its 4680 cells — which are more powerful and cheaper to produce — it would not be a surprise if future iterations of the flagship sedan and SUV are fitted with 4680 structural batteries. The 18650 cells are showing their age, after all, as Tesla has been using them since the days of the original Roadster.

If Tesla does utilize its 4680 cells for the Model S and Model X, the vehicles would likely be equipped with nickel-based batteries. The Tesla CEO has previously explained that the supply chain goes all the way back to raw materials like lithium and nickel, which are used to develop the company’s battery cells. During the last earnings call, Elon Musk mulled over the idea of Tesla consolidating its battery offerings down to 2 or 3 form factors, one nickel-based for high-powered vehicles like the Semi and the other iron-based for mass-produced cars like the Model 3.

“So right now, we kind of have the Baskin Robbins of batteries situation, where there’s so many formats and so many chemistries, that it’s like we’ve got like 36 flavors of battery at this point,” Musk said.

“This results in an engineering drag coefficient where each variants of cell chemistry and format requires as certain amount of engineering to maintain it and troubleshoot. And this inhibits our forward progress. So it is going to be important to consolidate to maybe—ideally two form factors, maybe three, but ideally two. And then just one nickel chemistry and one iron chemistry, so we don’t have to troubleshoot so many different variants,” he said.

With Tesla likely retiring its 18650 cells in the future, the Model S Plaid’s five-module battery pack could be seen as one of the final iterations of the technology that the company quite literally used to build its empire. And considering that the 18650 cells are being used in the Model S Plaid, there is no better swan song for the humble batteries.

Tesla’s six-seat, extended-wheelbase Model Y L has been approved for sale in Australia, as per newly published government documents.

The variant, listed as YL5NDB on the Australian government’s ROVER approval website, has confirmed that Tesla has received regulatory clearance to offer the extended Model Y to domestic customers.

Documents seen by Drive show that the Model Y L has been approved in Australia in a single dual-motor, all-wheel-drive configuration. While Tesla has not formally announced a launch date, vehicles are typically approved for Australian sale several months before arriving in showrooms.

The Model Y L is a longer version of the regular Model Y, designed to accommodate a six-seat layout with two seats in each row. It measures 177mm longer overall than the regular Model Y, at 4969mm, and features a 150mm longer wheelbase at 3040mm.

Australian approval documents list the Model Y L with the same nickel-manganese-cobalt battery pack used in the regular Model Y Long Range, which is expected to have a gross capacity of about 84kWh and a usable capacity of about 82kWh. Output is officially listed at 378kW in government filings, though real-world peak output may differ.

The Model Y L replaces the regular Model Y’s second-row bench with two captain’s chairs featuring heating, ventilation, and power adjustment. Heated third-row seats are also included.

Additional upgrades reported by Drive include an 18-speaker sound system, new front seats with single-piece backrests, and continuously variable shock absorbers. The only wheel option listed for the Australian model is 19-inch wheels.

In Europe, where the Model Y L has also received approval but has not yet launched, the variant is expected to claim up to 681km of WLTP range.

Elon Musk highlights one of Tesla FSD Supervised’s most underrated features

In his post on X, Musk wrote, “Tesla self-driving now recognizes hand signals.”

Tesla’s Full Self-Driving (Supervised) is able to recognize and respond to hand signals, as highlighted recently by CEO Elon Musk.

In his post on X, Musk wrote, “Tesla self-driving now recognizes hand signals.”

Musk shared the update in a quote reply to a video posted by Tesla Europe, which showed a vehicle operating with Full Self-Driving (Supervised) navigating a tight lane in the Netherlands while responding to hand gestures from a person directing traffic.

Hand signal recognition is an important capability for advanced driver-assistance and autonomous systems. In real-world driving, pedestrians, construction workers, parking attendants, and other drivers frequently use hand gestures to direct traffic, yield right of way, or indicate when it is safe to proceed. For a self-driving system operating in mixed environments, interpreting these non-verbal cues is critical.

Musk’s post comes as Tesla owners have surpassed 8 billion cumulative miles driven with FSD (Supervised) engaged. “Tesla owners have now driven >8 billion miles on FSD Supervised,” the company wrote in a post on X.

Annual FSD (Supervised) miles have increased sharply over the past five years. Roughly 6 million miles were logged in 2021, followed by 80 million in 2022, 670 million in 2023, 2.25 billion in 2024, and 4.25 billion in 2025. 

In the first 50 days of 2026 alone, Tesla owners logged another 1 billion miles. At the current pace, the fleet is trending toward approximately 10 billion FSD (Supervised) miles this year.

Tesla’s latest North America safety data, covering all road types over a 12-month period, also indicates that vehicles operating with FSD (Supervised) were recorded one major collision every 5,300,676 miles. By comparison, the U.S. average during the same period was one major collision every 660,164 miles.

Tesla appears to be expanding its Commercial Charging efforts in Central Europe. The job opening was highlighted by David Forer, Senior Project Developer for Charging at Tesla, on LinkedIn.

In a post on LinkedIn, Forer stated that Tesla is looking for a “high-energy executer to own Commercial Charging Sales in Central Europe.” He added that the role will involve closing commercial deals across Tesla’s “entire product range (Supercharging & Megacharging).”

The job listing specifies that the hire will lead the sale of Tesla’s high-power charging products, including Supercharger and Heavy Duty Charging, to major partners such as charge point operators, real estate owners, and retail companies. The role requires fluency in German and English and is based onsite in Munich.

Tesla already operates more than 75,000 Superchargers globally, though the Semi’s Megacharger network is still in its early stages. The inclusion of Heavy Duty Charging in the job description is notable, then, as it aligns with Tesla’s Megacharger infrastructure, which is designed to support the Tesla Semi.

Tesla CEO Elon Musk recently confirmed that the Tesla Semi is moving into high-volume production this 2026. In a post on X, Musk noted that “Tesla Semi starts high volume production this year.”

Aerial footage of the Tesla Semi Factory near Giga Nevada also shows that the facility looks nearly complete, with work now underway inside the facility. 

Tesla has also refreshed the Semi lineup on its official website, listing two variants: Standard and Long Range. The Standard trim offers up to 325 miles of range with an energy consumption rating of 1.7 kWh per mile, while the Long Range version provides up to 500 miles. 

Both variants support fast charging and can recover up to 60% of range in 30 minutes using compatible infrastructure such as the Megacharger Network.

The presence of Heavy Duty Charging in a Central Europe-focused sales role could indicate that Tesla is preparing charging infrastructure ahead of wider Semi deployment in the region. While Tesla has not formally announced a European launch timeline for the Semi, the vehicle, particularly its range, makes it an ideal fit for the area.
