BYD Seal 07Several Chinese carmakers are developing their own smart-driving chips, aiming to cut costs, move faster, and rely less on third parties.Chinese EV makers are designing their own smart-driving chips to cut costs and rely less on suppliers.BYD, NIO, XPeng, and Li Auto want more control over the hardware behind driver assistance.In-house chip design could make Chinese EVs cheaper, smarter, and faster to develop.The first part of China's electric car rise was about batteries, an industry it now dominates. Cheaper, better batteries made at an enormous scale helped turn companies like BYD from regional players into global juggernauts with their eyes on legacy automakers. Now, Chinese carmakers are looking at the next expensive EV part: the chips that power advanced driver-assistance systems and increasingly automated driving features.Gasgoo says 2026 looks set to be a major year for Chinese automakers developing their own smart driving chips. BYD, NIO, XPeng, and Li Auto all have in-house chip design projects in progress because advanced driver-assistance hardware is becoming increasingly important—and too expensive—to leave entirely to suppliers.AdvertisementAdvertisementThe industry shift is bigger than propulsion. Cars are increasingly becoming software-defined machines, and in China specifically, advanced driver-assistance features are quickly trickling down from expensive flagship models into much cheaper mainstream EVs. That puts pressure on carmakers to make the hardware cheaper, more efficient, and more closely tied to their own software.The most advanced cars available in China are rolling sensor platforms, running cameras, radar, lidar in some cases, driver-monitoring systems, and increasingly ambitious assisted-driving software. The chip that processes all of that is becoming increasingly important, and automakers want more flexibility, independence, and savings by no longer outsourcing this technology.BYD is the cleanest example of how far this has gone. It is already the world's second-largest EV battery maker, according to SNE Research, with a global battery market share of 14.4% in the first five months of 2026. Now it has unveiled its first in-house smart-driving chip, and founder Wang Chuanfu says BYD can supply the key chips needed for its intelligent vehicles.If BYD wasn't already making Western automakers nervous through its huge global push for expansion, the announcement that it was making its own chips probably did the trick. And while Nvidia is offering a broadly adaptable platform of chips for different driving needs, BYD is tailoring its chips specifically to its own needs, aiming to cut costs.AdvertisementAdvertisementAccording to the Wall Street Journal, BYD has announced plans to invest over $14.75 billion into intelligent technology development over the next three years. Its Xuanji A3 chip, a specialized 4-nanometer semiconductor, is designed to support Level 3 and Level 4 automated driving, providing capabilities comparable to Nvidia's Thor chips but reportedly at one-third the price.However, designing a chip is not the same thing as escaping the semiconductor supply chain. Automotive AI chips still rely heavily on external parts and manufacturing, and Chinese companies continue to outsource production of many advanced semiconductors. But even partial control matters if it lets carmakers like BYD save money and design hardware tailored to their own cars.More On ThisGM's CEO Issues Warning Over Cheap Chinese EVs In North AmericaA New Car Chip Shortage Is Brewing—And It's All AI's FaultTesla's Next Gen Chips Are Coming. What Does That Mean For Self-Driving?Inside Ford's Plan To Outfox China's EV CompaniesNIO is another Chinese carmaker chasing the same idea. Its 5-nanometer Shenji NX9031 chip has already been used in NIO models, and Chinese industry reporting has said it could save roughly 10,000 yuan, or about $1,400, per car compared with Nvidia-based hardware.AdvertisementAdvertisementXpeng may be the most interesting case because its chip ambitions could move beyond its own cars. Its Turing AI chip, released in 2024 and presented as the "world's first multi-end universal chip," was developed for autonomous driving, but not just for Xpeng's own cars. It has been working with Volkswagen on China-market EVs with Xpeng tech, and it is reportedly in talks with other car brands.Li Auto has also unveiled an AI chip for autonomous driving, the Mach M100, with a 5-nanometer architecture. It was specifically designed for its flagship vehicle, the L9 Livis SUV. Other companies are also likely working on similar solutions, too, and this could be the Chinese car industry's next big push after it took control of batteries, squeezed cost out of the car, and moved faster than rivals expected.Now, the same thing seems to be happening with the silicon that lets cars drive themselves. That should worry Western automakers that aren't making their own chips and are relying solely on chips from Nvidia, Qualcomm, Mobileye, Horizon Robotics, and others. This could further strengthen Chinese automakers' cost advantage over Western rivals and make their cars even harder to match on price and technology.
