Tesla is reportedly looking to strike a deal with Sigma Lithium Resources Group, a Brazilian startup company that can supply Tesla with lithium, a key ingredient of electric car batteries.

Sigma was granted a license to begin mining lithium by the Environmental Authority of the State of Minas Gerais, the Council of Environmental Policy on June 11, 2019. The license will allow Sigma to mine hard rock lithium, a crucial piece of automotive-grade lithium-ion batteries, for six-years, making the company an extremely valuable asset for automakers pursuing electric mobility.

It should be noted that Brazil was ranked No.7 among countries with the highest concentration of lithium. A large percentage of the metal, used primarily for the production of glass and batteries, is available in the Minas Gerais area.

Sigma has previously met with Tesla’s current lithium supplier, Ganfeng Lithium, a Chinese-based company that is currently the country’s largest supplier of the material. Tesla reportedly organized the meeting between both parties that unfortunately did not end in a deal. Sigma CEO Calvyn Gardner cited the Brazilian startup company could not meet the financial or production needs that Ganfeng requested.

“There’s a bunch of other things that they [Ganfeng] need, not just prices, but other demands which are a little more complicated that sort of restricts Sigma to almost supplying purely into China. It’s not really what we think we should be doing over the long term,” Gardner remarked at a mining conference in Brazil. 

Gardner, who calls himself a “fan” of Tesla, was interested in purchasing a Model 3 for himself but ran into roadblocks as Tesla does not have a sales office in the South American country. After import taxes would have more than doubled the cost of the Model 3, he decided to hold off.

Striking a deal with Tesla would directly benefit both companies. Tesla currently uses Gigafactory partner Panasonic as its battery supplier but appears to be seeking to expand it lineup of partners, especially after the Japanese electronics conglomerate has cut its profit outlook due to China’s trade war with the US. Tesla’s acquisition of Maxwell Technologies, an ultracapacitor producer, also hinted at the electric car maker’s plans to pursue battery technology beyond its Panasonic partnership.

It would be beneficial for both Tesla and Sigma to strike a deal directly, with the Brazilian company shipping the lithium to the electric car maker. Unfortunately, this could only happen once makers of cathodes, another primary component of batteries, set up facilities in the United States.

Other large automakers that are bursting into the electric transportation market, such as Volkswagen and BMW, have held talks with Sigma already. Gardner, a graduate of the University of South Africa, is optimistic over the talks with both German automakers. “Having options to get lithium from other jurisdictions and that you can supply over the long term,” he said. “That’s what all of them are interested in and we think Sigma can do that.”

There is no shortage of money or optimism in the lithium mining industry. Sigma has recently received a $30 million loan from Japanese trading group Mitsui, according to Reuters. The money is planned to be used in building Sigma facilities, and will be repaid in a big way: a third of Sigma’s planned output of lithium from its Minas Gerais mining facility.

Tesla just tipped its hand on a major Cybercab feature as production hits Plaid Mode

Tesla has delivered a clear signal that its Robotaxi ambitions are shifting into high gear. On April 17, longtime factory observer and drone pilot Joe Tegtmeyer captured drone footage and still images showing approximately 14 freshly built Cybercabs parked in the outbound lot—each one conspicuously lacking a steering wheel.

Tesla just tipped its hand on a major Cybercab feature as it is putting production into Plaid Mode, but a clear indication of what the company plans to do with the vehicle is now apparent.

Tesla has delivered a clear signal that its Robotaxi ambitions are shifting into high gear, and it’s doing it with full autonomy in mind.

On April 17, longtime factory observer and drone pilot Joe Tegtmeyer captured drone footage and still images showing approximately 14 newly built Cybercabs parked in the outbound lot, each conspicuously lacking a steering wheel, and potentially pedals.

Tegtmeyer’s post highlighted the significance of this development: The images and video reveal sleek, two-seat Cybercabs in their final production form: no driver controls, no side mirrors, and the minimalist interior first unveiled at Tesla’s “We Robot” event in October 2024.

These units contrast with earlier test vehicles spotted at the factory’s crash-test area, which carried temporary steering wheels and pedals to meet current federal regulations during data-collection phases.

The outbound-lot vehicles appear complete, with production wheels, tire stickers, and the signature Cybercab styling ready for deployment.

This sighting represents a pivotal transition. Tesla designed the Cybercab from the ground up as a purpose-built robotaxi, engineered for unsupervised Full Self-Driving (FSD) operation. Removing manual controls eliminates cost, complexity, and weight while maximizing interior space and range.

The move also signals that Tesla has cleared initial validation hurdles and is now building vehicles to the exact specification intended for commercial robotaxi service.

Industry watchers note the timing aligns with Tesla’s broader rollout plans. Production of early Cybercabs began in late 2025 and early 2026, primarily for internal testing and regulatory compliance.

Federal Motor Vehicle Safety Standards currently limit vehicles without steering wheels to 2,500 units per year without exemption, a cap that Tesla is navigating through ongoing filings.

The appearance of steering-wheel-free units in the outbound lot suggests the company is preparing a small initial fleet—likely for Austin pilot operations or further validation—while pushing for regulatory relief to scale output.

The development comes as Tesla ramps its dedicated Cybercab line at Gigafactory Texas. If the Monday surge materializes as predicted, observers expect dozens more units to accumulate rapidly.

With unsupervised FSD advancing and regulatory conversations ongoing, these wheel-less Cybercabs parked under the Texas sun represent more than hardware—they embody Tesla’s bet that autonomous mobility is no longer a prototype dream but an imminent reality.

Tesla preps new Model Y trim for India, a once-elusive market

Tesla’s journey into India began with significant hurdles. For years, the electric vehicle giant faced steep import tariffs ranging from 70 percent to 110 percent on fully built vehicles, which dramatically inflated prices and stalled entry plans.

Tesla is preparing to bring its newest Model Y trim to India, a once-elusive market that was hesitant to allow any vehicles built outside the market into its automotive sector.

Now, it is preparing to allow China-built Model Y vehicles to come into the country, in an effort to expand sales and offer what is a widely-requested variant to Indian customers.

Tesla’s journey into India began with significant hurdles. For years, the electric vehicle giant faced steep import tariffs ranging from 70 percent to 110 percent on fully built vehicles, which dramatically inflated prices and stalled entry plans.

Elon Musk repeatedly criticized these duties as among the world’s highest, making premium EVs like the Model Y prohibitively expensive for most buyers in the price-sensitive market.

After prolonged negotiations and multiple delays, Tesla finally debuted in July 2025 with a quiet rollout focused on luxury segments. It opened showrooms in Mumbai and New Delhi, importing standard Model Y SUVs from its Shanghai Gigafactory.

Yet the launch proved challenging: vehicles carried sticker prices near $70,000, leading to tepid demand. Bloomberg reported only about 600 orders in the first two months, while official data showed just 227 registrations for all of 2025—far below internal targets. By early 2026, the company offered discounts of up to ₹200,000 ($2,200) to clear unsold inventory.

Now, less than a year later, Tesla is demonstrating resilience and adaptability. According to a Bloomberg report on April 17, the company is preparing to launch the Model Y L—a six-seat, long-wheelbase variant with three-row seating—as early as next week.

This marks Tesla’s first new product introduction in India since its initial entry. Notably, the newest Model Y configuration, which debuted in China in 2025 and features extended space tailored for families, will once again be exported directly from Tesla’s Shanghai Gigafactory.

The move highlights a shift from early struggles to a more targeted approach, leveraging an existing platform to better suit Indian preferences for multi-generational, spacious SUVs without committing to immediate local production.

While tariffs continue to keep pricing in the premium segment, the six-seater variant aims to broaden appeal beyond early luxury adopters by addressing practical family needs.

This evolution, from battling high barriers and disappointing initial sales to exporting its latest derivative model, signals cautious optimism.

Success with the Model Y L could strengthen Tesla’s foothold in one of the world’s most populous markets and potentially pave the way for deeper investments, such as localized manufacturing, should tariff relief or policy shifts materialize.

For now, the China-to-India supply chain represents a pragmatic bridge over the very obstacles that once made entry so difficult.

The golden age of autonomous ridesharing is arriving, and Tesla is making sure we can all picture a future that looks like the future. A recent teaser posted to X shows a Cybercab parked outside a home, and with a clear message that your everyday life may soon look like this when the driverless vehicles shows up at your door.

Tesla has begun the rollout of its Robotaxi service across US cities, and the production of its dedicated, fully-autonomous Cybercab vehicle. The first Cybercab rolled off the Giga Texas assembly line on February 17, 2026, with volume production now targeted for this month. Additionally, the Robotaxi service built around it is already running, without human drivers, in US cities.

The Cybercab is built without a steering wheel, pedals, or side mirrors, designed from the ground up for unsupervised autonomous operation. Musk described the manufacturing approach as closer to consumer electronics than traditional car production, targeting a cycle time of one unit every ten seconds at full scale.

Drone footage from April 13, 2026 captured over 50 Cybercab units on the Giga Texas campus, with several clustered near the crash testing facility. Musk has noted that Tesla plans to sell the Cybercab to consumers for under $30,000, and owners will be able to add their vehicles to the Tesla robotaxi network when not in personal use, potentially generating income to offset the vehicle’s purchase cost. That model changes the math on vehicle ownership in a meaningful way, making a car something closer to a depreciating asset that can also earn by paying itself off and generate a profit.

During Tesla’s Q4 earnings call, the company confirmed plans to expand the Robotaxi program to seven new cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas. The service already runs without safety drivers in Austin, and public road testing of the Cybercab has expanded to five states, including California, Texas, New York, Illinois, and Massachusetts.
