Tesla is reportedly considering purchasing Sigma Lithium, a Brazillian lithium mining company, for an estimated $3 billion.
Tesla and its CEO Elon Musk have shown a continued interest in the extraction and refinement of lithium over the past five years. With the company’s exponentially growing demand for the substance, and its alacrity to vertically integrate, a corporate purchase of a lithium miner certainly is within its MO. But now, Tesla may be closer than ever to such a purchase, as Bloomberg reports that the automaker is exploring purchasing Sigma Lithium for $3 billion.
Sigma Lithium is one of the largest lithium extractors in South America, thanks in large part to what the company calls “the largest hard rock lithium deposit in the Americas.” Located in the South Eastern State of Minas Genrias, the massive mining operation has been in operation since 2018. Importantly to Tesla, Sigma’s proximity to the Atlantic coast means its extracted lithium can easily be shipped across the globe.
Simga Lithium has not responded to Teslarati or Bloomberg regarding the potential sale, and representatives of Tesla CEO Elon Musk refused to comment to Bloomberg on what they called “rumors.”
Following the leak in information, shares of Sigma Lithium on the NASDAQ exploded by more than 25% in after-market trading.
What makes the Sigma acquisition potentially highly attractive to Tesla, besides its proximity to the coast, is its growth potential. According to Sigma Lithium’s website, it plans to increase output to 270,000 metric tonnes of lithium annually, with the more distant goal of producing 766,000 metric tonnes of lithium annually in the coming years. Furthermore, with a nearby abundant supply of water and hydropower on the Jequitinhonha River, the operation can achieve this growth at a lower cost than other operations.
With the acquisition of Sigma Lithium, Tesla would only be a couple of steps away from a completely vertically integrated lithium supply chain. Tesla already produces its own battery cells, and with an upcoming lithium refining facility in Corpus Christi, Texas, raw lithium from Sigma’s operation in Brazil could help the automaker continue to tame battery costs.
With Tesla’s profit margins becoming the envy of the auto industry, we may see an ever-increasing number of automakers moving into lithium extraction and refining. However, with the expertise and property holdings that mining companies currently possess, this move could come at the astronomical cost of a corporate acquisition. It remains unclear if other automakers will follow in Tesla’s footsteps.

Elon Musk confirms Tesla is already rolling out a new feature for in-car Grok
Tesla is already making in-car Grok more robust with a simple but effective feature that CEO Elon Musk says is “coming.”

Tesla CEO Elon Musk has confirmed that the company will roll out a new feature for in-car Grok as it is rolling out to vehicles for the first time.
Grok was just recently added as a feature to Tesla vehicles within the past week, but owners are already requesting some small changes to make it more convenient to use.

The first is already on the way, Musk confirmed, as WholeMarsBlog requested a simple, but useful feature for Grok as it is used within Tesla vehicles.
Whole Mars requested that “Hey Grok” be used as a wake word, automatically activating the AI assistant without having to touch any buttons. Musk confirmed it is already in development and on the way to vehicles:
Coming

This feature is incredibly similar to that of “Hey Siri” with iPhones and other iOS devices. The phone will recognize your voice and hear that prompt, automatically activating Siri. Apple’s assistant will then perform whatever task it is asked to perform. It’s a simple but effective performance feature.
Grok is already getting its first reviews from owners as it rolls out to owners for the first time. It is a long time coming, too. Tesla has been hinting that Grok would be enabled in the vehicles for a while now, and it just started its initial rollout last week.
After using @grok in my Tesla tonight, I’m insanely impressed.
I honestly went into it a bit skeptical on how useful it would actually be, but I asked it some real genuine questions and it nailed it every time.

Grok is available in vehicles with the AMD chip and requires Premium Connectivity or a WiFi connection to use.

Tesla reveals key detail of Supercharger Diner, but it’s bigger than you think
Tesla has finally released one key detail about the Supercharger Diner, and it is bigger than what it appears at face-value.

Tesla has revealed a key detail of its Supercharger Diner as its launch date appears to be nearing, based on what we are seeing at the site currently.
The Supercharger Diner is located on Santa Monica Boulevard in Los Angeles and was first proposed as an idea by CEO Elon Musk back in 2018. Musk envisioned a drive-in movie-style 1950s-inspired diner that would feature elements such as servers on roller skates, large movie screens, and a menu inspired by classic treats from several decades ago.
A project that first broke ground in 2023, the Supercharger Diner has been in development for over two years, as Tesla performed demolition work at the site back in February of that year.
It has slowly moved forward, and drone footage shot this week seems to show things are nearly up and running. Musk even mentioned that he had eaten at the Diner Supercharger this week.
There are still details that Tesla has yet to announce and confirm. The most important thing is regarding the menu that will be served at the diner.
Tesla has not hinted at what it will be making for patrons at the restaurant, but Musk commended the food and said the diner would be one of the coolest spots in LA.

However, we now have details on another important thing about the restaurant: the hours.
Images taken by Aaron Cash of ABetterTheater.com show the diner will be open 24/7, as it appears on the front doors of the diner:

At first thought, it seems this will operate like any other diner, as many are open for 24 hours a day. Diners typically serve large menus with numerous options, catering to the tastes and moods of anyone who walks in.
People of all walks of life eat at diners, as the food is typically affordable, tasty, and available at any hour to serve those who are night owls or those who work non-typical schedules.
However, Tesla is a bit different, and it seems that this new venture into food service could eventually transition from human servers and cooks to robots, most notably the company’s in-house project of Optimus.
It is something straight out of a Star Wars movie. I can think of Obi-Wan Kenobi visiting Dex in his diner in Attack of the Clones to figure out where a poison dart was sourced from:
Eventually, Optimus will likely be working as an employee in the Tesla Diner, and 24/7 operation will be performed by the humanoid robot that aims to eliminate trivial tasks from humans.

First glimpse of Tesla Model Y with six seats and extended wheelbase
It’s longer and taller than the regular Model Y, and it has a cool new badge.

Tesla’s extended wheelbase Model Y has been announced by the electric vehicle maker on its official Weibo page in China. At the same time, details of the upcoming vehicle have been listed in the China Ministry of Industry and Information Technology’s (MIIT) new regulatory catalog.
The extended wheelbase Model Y
Tesla announced the upcoming vehicle on its official Weibo page, with the company noting that the new car will be called the “Model Y L.” Images posted by the company showed that the Model Y L will feature a “Model Y” badge with a stylized “Y” graphic. A teaser image of the vehicle taken from its side also emphasizes the extra space that was gained from its extended wheelbase.
The MIIT listing for the Model Y L indicated that the vehicle would be 4,976 mm long, 1,920 mm wide, and 1,668 mm high. Its wheelbase was listed in the MIIT’s catalog as 3,040 mm. In comparison, the new Model Y is currently 4,797 mm long, 1,920 mm wide, and 1,624 mm high, with a wheelbase of 2,890 mm.
Six seats and some power
Most notably, the extended wheelbase Model Y was listed in the MIIT regulatory catalog as a six-seat model. The vehicle is also listed with the product model number TSL6500BEVBA0, as noted in a CNEV Post report. And as hinted in Tesla China’s Weibo post, the vehicle will be released sometime in the fall.
The Model Y L is listed as a dual motor vehicle with peak power outputs of 142 kW and 198 kW for the front and rear motors. The vehicle is also listed with ternary batteries supplied by LG Energy Solution, and it reportedly weighs 2,088 kilograms (4603 pounds). In comparison, the new Model Y Dual Motor AWD weighs 4391 pounds.
Tesla China has not hinted at the price of the new Model Y L, though expectations are high that the vehicle will be priced at about RMB 400,000 ($55,764). It also remains to be seen if the Model Y L will also be produced in Tesla’s vehicle factories in the United States and Germany.
