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 revealed plans to develop its own maps internally to fix Navigation issues and give owners more control over their routing.
On the company’s Q3 2026 Earnings Call, a question was asked about FSD Navigation issues, particularly speed limit recognition, parking, and routing. These are issues that surface from version to version and seem to be seriously challenging for Tesla’s AI team to resolve.
Tesla’s Head of AI, Ashok Elluswamy, said in response to the question:
“You’re totally right that we shouldn’t be depending on external people’s maps. So we are building our own maps, but not like the same way as OneMoreMap. We are building an entirely new architecture with essentially AI-based mapping and navigation.”
He continued:
“It’s going to be super awesome. It’s going to be integrated with voice. You can talk to it, ask for different routes. It’s going to learn your personalized preferences, plus the fleet preferences. The collective intelligence of all the cars is going to flow into making the maps and navigation super cool.”
Elluswamy said this issue should be confronted, and the mapping should be available for people by the time the v15 release starts deploying to customers.
“And over the next several months,” he added, “it’s just going to take over all of the navigation functions, parking, destination handling. And it will know you better than you know yourself in some regard for the driving task, and then handle it fully.”
Tesla Summon got insanely good in FSD v14.3.2 — Navigation? Not so much
Navigation is perhaps the most notable complaint with FSD, and although it has gotten better, it is still flawed. Much of the time, FSD will take people on routes that are not preferred by the driver, but Tesla tried to combat this with a routing feature in the Summer 2026 Update.
Tesla currently relies on Google for map data, but it is sort of counterintuitive to believe the company would rely on a third party for this. These improvements will be welcome, as routing and navigation have been such a pain point for so many owners for so long.

Tesla Full Self-Driving (Supervised) showed a record attach rate at delivery for new vehicles in the third quarter of 2026.
75 percent of new vehicle deliveries in North America included a subscription to FSD software, up from 55 percent in the prior quarter, a 20-percentage-point sequential gain in the company’s most mature market.
Tesla Q3 2026 Earnings results: in-line revenues, slight beat on EPS
Tesla shed light on the Q3 Shareholder Deck that 75 percent of new deliveries came with an FSD subscription:
“FSD (Supervised)⁴ attach rate continued to grow, reaching over 75% of new vehicle deliveries in North America – our most mature market – a nearly twenty percentage point sequential increase. We believe that FSD is driving demand in markets where it is available, and we continue to work with regulators to get it approved in other markets. “
The higher attach rate accompanied strong growth in the overall FSD consumer base, as active subscriptions rose to 1.75 million, a 67 percent year-over-year increase. For the first time, more than half of paid customers are on the monthly subscription, which is priced at $99 per month in the U.S.

The transition to subscriptions has accelerated since Tesla discontinued the one-time purchase option in most markets earlier this year. The recurring model improves revenue visibility and margins compared with large upfront payments. With three-quarters of North American deliveries now including FSD, the software is now an evidently large contributor to Tesla’s economics and ancillary revenue.
Geographic expansion remains important for further gains. FSD is now available in nine countries in the EU, and more than 100,000 customers have driven over 160 million kilometers. Tesla is pursuing broader EU-wide approval, with a related vote expected in December. Similar progress in additional markets could support higher attach rates beyond North America.
These results came as Tesla had a strong quarterly delivery performance of 486,532 vehicles in the quarter, which came with its largest passenger-vehicle backlog in four years. Battery supply continued to limit volume, but the company has pointed to FSD as a clear difference-maker that is helping sustain demand. As supervised capabilities improve, the attach rate will likely continue to improve.
At face value, it is a key measure of how Tesla is converting sales into autonomy progress.
Update: 10/22 10:51a – Para 1 consumers changed to “customers” for accuracy.
Tesla Cybercab units finally got a definitive date for when they will be able to be purchased by customers, ending speculation regarding whether the fully autonomous vehicle would be available in the near term.
During Tesla’s third-quarter 2026 earnings call on October 21, Vice President of Engineering Lars Moravy said the company is aiming to begin delivering its purpose-built Cybercab robotaxi to customers before year-end.
🚨 In short, Cybercabs are slated to go to customers by end of the year. All units are going into Robotaxi fleet currently, per @larsmoravy
Cybercab will be “transport-as-a-service,” but vast majority of Cybercab will be “Tesla-owned,” @elonmusk says https://t.co/R8Qu8QWdmp
— TESLARATI (@Teslarati) October 21, 2026
“We’re trying to get Cybercabs to customers by the end of this year, 2026,” Moravy said. He added that production is underway on the line at Gigafactory Texas, but “all of those are currently going to our own internal Robotaxi fleet.”
Moravy explained that as operations scale, Tesla will “mainly deliver fully designed autonomous vehicles to our customers,” with the Cybercab as the first such vehicle. Initial customer deliveries will start small while the company gains experience with delivery logistics, ownership models, fleet management, and operating autonomous vehicles outside its direct control.
CEO Elon Musk reinforced the limited nature of private sales, describing the Cybercab primarily as a “transport-as-a-service” offering rather than a personal ownership vehicle like the Model 3, Model Y, or upcoming Roadster. “The vast majority of the Cybercab stuff will be Tesla-owned and transport-as-a-service,” Musk said.
The Cybercab is a two-seater vehicle developed by Tesla without a steering wheel or pedals. It relies completely on Tesla’s Full Self-Driving suite and has been in production since February. Early units have been put in Tesla’s Robotaxi service as of early September, when the company launched rides to the public. Tesla previously indicated it would aim to sell Cybercabs for about $30,000.
Unsupervised Full Self-Driving is expected to ship to consumer cars during Q2 2027, Ashok Elluswamy, Tesla’s Head of AI, indicated during the call. Early buyers or fleet operators may receive vehicles whose autonomous operation remains geographically restricted due to lagging regulatory agencies. There are some hurdles that remain ahead of Cybercab deliveries.
