The Tesla Model 3 is driving the chip industry’s transition into the post-silicon age
The winds are changing in the global chip industry, and the Tesla Model 3 may very well be one of the catalysts for the impending shift. Tesla became one of the first automakers to use silicon carbide (SiC) chips in a mass-produced vehicle. And by incorporating SiC chips into the Model 3, the American automaker ended up giving the material some momentum in the EV supply chain
Tesla’s use of silicon carbide in the Model 3 was a bold move, considering that silicon has long been the material of choice in the semiconductor industry. Since replacing germanium crystals in the 1960s, silicon has effectively ushered in a golden age of semiconductors. But today, other materials such as silicon carbide have emerged to challenge silicon for its throne.
Silicon carbide contains silicon and carbon, and with chemical bonds that are stronger than those in plain silicon, it holds the title of the world’s third-hardest substance. As noted in a Nikkei Asia report, processing silicon carbide requires advanced technology, but its stability, among its other properties, allows chipmakers to cut energy loss by more than half compared to conventional silicon wafers. SiC chips are also good at dissipating heat, paving the way for smaller inverters.
Masayoshi Yamamoto, a professor at Nagoya University in Japan, noted that these advantages are well represented in the Tesla Model 3’s design. “The Model 3 has an air resistance factor as low as a sports car’s. Scaling down inverters enabled its streamlined design,” Yamamoto said.
The runaway success of the Tesla Model 3 effectively sent shockwaves in the chip industry. And these shockwaves have started to inspire a wave of commitments on silicon carbide chips. In June alone, German chipmaker Infineon Technologies unveiled an SiC module for EV inverters. Hyundai later announced that these Infineon-made SiC chips would be used in its next-generation electric cars. The South Korean automaker added that by using Infineon’s SiC chips, its EVs could see a 5% improvement in range compared to vehicles equipped with plain silicon chips.
Kazuhide Ino, chief strategy officer at Japanese chipmaker Rohm, noted that at this stage, makers of silicon carbide chips have reached a point where they are already competing with each other. “Thus far, chipmakers have worked together to build up the silicon carbide market, but we’ve reached the stage of competing with each other,” he said.
French market research firm Yole Developpement noted in a forecast that the market for silicon carbide chips would likely grow sixfold by 2026 compared to 2020. This should make the SiC chip segment into a $4.48 billion market. A lot of this would rely on whether production costs for SiC chips could be reduced adequately, however, as SiC chips are still more expensive than conventional silicon chips today. That being said, the gap between silicon and SiC chips has been narrowing. Five years ago, SiC chips were about 10X more expensive than traditional silicon. Today, they’re only twice as expensive.

Tesla rolls out new Supercharging safety feature in the U.S.
Tesla has rolled out a new Supercharging safety feature in the United States, one that will answer concerns that some owners may have if they need to leave in a pinch.
It is also a suitable alternative for non-Tesla chargers, like third-party options that feature J1772 or CCS to NACS adapters.
The feature has been available in Europe for some time, but it is now rolling out to Model 3 and Model Y owners in the U.S.
With Software Update 2026.2.3, Tesla is launching the Unlatching Charge Cable function, which will now utilize the left rear door handle to release the charging cable from the port. The release notes state:
“Charging can now be stopped and the charge cable released by pulling and holding the rear left door handle for three seconds, provided the vehicle is unlocked, and a recognized key is nearby. This is especially useful when the charge cable doesn’t have an unlatch button. You can still release the cable using the vehicle touchscreen or the Tesla app.”
The feature was first spotted by Not a Tesla App.
This is an especially nice feature for those who commonly charge at third-party locations that utilize plugs that are not NACS, which is the Tesla standard.
For example, after plugging into a J1772 charger, you will still be required to unlock the port through the touchscreen, which is a minor inconvenience, but an inconvenience nonetheless.
Additionally, it could be viewed as a safety feature, especially if you’re in need of unlocking the charger from your car in a pinch. Simply holding open the handle on the rear driver’s door will now unhatch the port from the car, allowing you to pull it out and place it back in its housing.
This feature is currently only available on the Model 3 and Model Y, so Model S, Model X, and Cybertruck owners will have to wait for a different solution to this particular feature.

LG Energy Solution pursuing battery deal for Tesla Optimus, other humanoid robots: report
Optimus is expected to be one of Tesla’s most ambitious projects, with Elon Musk estimating that the humanoid robot could be the company’s most important product.
A recent report has suggested that LG Energy Solution is in discussions to supply batteries for Tesla’s Optimus humanoid robot.
Optimus is expected to be one of Tesla’s most ambitious projects, with Elon Musk estimating that the humanoid robot could be the company’s most important product.
Humanoid robot battery deals
LG Energy Solution shares jumped more than 11% on the 28th after a report from the Korea Economic Daily claimed that the company is pursuing battery supply and joint development agreements with several humanoid robot makers. These reportedly include Tesla, which is developing Optimus, as well as multiple Chinese robotics companies.
China is already home to several leading battery manufacturers, such as CATL and BYD, making the robot makers’ reported interest in LG Energy Solution quite interesting. Market participants interpreted the reported outreach as a signal that performance requirements for humanoid robots may favor battery chemistries developed by companies like LG.
LF Energy Solution vs rivals
According to the report, energy density is believed to be the primary reason humanoid robot developers are evaluating LG Energy Solution’s batteries. Unlike electric vehicles, humanoid robots have significantly less space available for battery packs while requiring substantial power to operate dozens of joint motors and onboard artificial intelligence processors.
LG Energy Solution’s ternary lithium batteries offer higher energy density compared with rivals’ lithium iron phosphate (LFP) batteries, which are widely used by Chinese EV manufacturers. That advantage could prove critical for humanoid robots, where runtime, weight, and compact packaging are key design constraints.

Tesla receives approval for FSD Supervised tests in Sweden
Tesla confirmed that it has been granted permission to test FSD Supervised vehicles across Sweden in a press release.
Tesla has received regulatory approval to begin tests of its Full Self-Driving Supervised system on public roads in Sweden, a notable step in the company’s efforts to secure FSD approval for the wider European market.
FSD Supervised testing in Sweden
Tesla confirmed that it has been granted permission to test FSD Supervised vehicles across Sweden following cooperation with national authorities and local municipalities. The approval covers the Swedish Transport Administration’s entire road network, as well as urban and highways in the Municipality of Nacka.
Tesla shared some insights into its recent FSD approvals in a press release. “The approval shows that cooperation between authorities, municipalities and businesses enables technological leaps and Nacka Municipality is the first to become part of the transport system of the future. The fact that the driving of the future is also being tested on Swedish roads is an important step in the development towards autonomy in real everyday traffic,” the company noted.
With approval secured for FSD tests, Tesla can now evaluate the system’s performance in diverse environments, including dense urban areas and high-speed roadways across Sweden, as noted in a report from Allt Om Elbil. Tesla highlighted that the continued development of advanced driver assistance systems is expected to pave the way for improved traffic safety, increased accessibility, and lower emissions, particularly in populated city centers.
Tesla FSD Supervised Europe rollout
FSD Supervised is already available to drivers in several global markets, including Australia, Canada, China, Mexico, New Zealand, and the United States. The system is capable of handling city and highway driving tasks such as steering, acceleration, braking, and lane changes, though it still requires drivers to supervise the vehicle’s operations.
Tesla has stated that FSD Supervised has accumulated extensive driving data from its existing markets. In Europe, however, deployment remains subject to regulatory approval, with Tesla currently awaiting clearance from relevant authorities.
The company reiterated that it expects to start rolling out FSD Supervised to European customers in early 2026, pending approvals. It would then be unsurprising if the company secures approvals for FSD tests in other European territories in the coming months.
