(Bloomberg) — BYD Co., the world’s largest electric vehicle maker, unveiled a series of technology advances, including what it calls China’s first automotive-grade 4-nanometer chip for self-driving cars.

The semiconductor breakthrough approaches the lead of Chinese tech giant Huawei Technologies Co., which currently makes chips with a geometry of 7 nanometers but has pledged to debut 1.4nm chips by 2031. It’s designed to allow BYD’s computer-assisted driving to stand out from a crowded Chinese EV market that includes rivals such as Xpeng Inc. and Xiaomi Corp.

BYD Chief Executive Officer Wang Chuanfu announced the Xuanji A3 chip at an event Thursday at its Shenzhen headquarters, saying it has the best energy efficiency in the industry and uses 20% less power than similar semiconductors.

The most advanced chip globally is the 2nm N2 node made by Taiwan Semiconductor Manufacturing Co. The nanometer measure is used to indicate the size of transistors on a chip. The smaller a transistor becomes, the more can be fitted on a chip, which in turn will become more powerful.

The Xuanji A3 is the centerpiece of BYD’s new laptop-sized central computing platform. The company said the unified software suite speeds up three previously separate domains within an EV: its smart cockpit of dashboard controls, an advanced driver-assistance feature and the core electric propulsion.

BYD is waiting for China to formalize legislation allowing more consumer-facing deployment of self-driving vehicles, which the company expects to happen as soon as 2027. The carmaker is prepared to roll out products at that level of autonomy when the time comes, according to Yang Dongsheng, a senior vice president.

While it doesn’t offer that fully driverless technology yet, BYD plans to expand its partially automated driver-assist system across all models in China. It will deploy that feature with laser-mapping sensors known as LiDAR to mass-market EVs such as its compact hatchback Seagull, which starts at 69,800 yuan ($10,300).

The technology, which automakers usually reserve for premium vehicles, will be available at a standard price of 12,000 yuan. Offering the upgraded driver assistance as a paid-for add-on gives the company a new revenue stream amid a fierce price war in China that has crunched earnings.

“Even the affordable Seagull or Dolphin models can be equipped with the smart driving experience that usually goes with luxury cars,” Wang said. “Our add-on package is the most sincere in the industry, priced only at cost.”
