TLDRs;
- Volkswagen will co-develop advanced autonomous driving chips in China with Horizon Robotics under its Carizon joint venture.
- The chip aims for 500–700 tera operations per second (TOPS), targeting a rollout within three to five years.
- It will power Volkswagen’s next-generation EV platform, with 80% of China models built on it by 2030.
- The move marks VW’s response to Chinese rivals like BYD, Xpeng, and Nio, who are also making in-house AI chips.
Volkswagen is doubling down on its China strategy with a plan to develop its own advanced semiconductors in the country, a bold step toward autonomy and digital control in its next generation of electric vehicles.
Through its joint venture, Carizon, with Chinese AI chipmaker Horizon Robotics, the German automaker aims to deliver a system-on-a-chip (SoC) within three to five years.
The chip will serve as the brain of Volkswagen’s semi-autonomous vehicles in China, processing streams of visual and sensor data with projected computing power of 500 to 700 tera operations per second (TOPS). That would place it among the top-performing automotive processors globally, comparable to the neural processing units used by Tesla and ZF.
Volkswagen’s goal is to egain lost ground in China’s electric vehicle market, where domestic giants like BYD, Nio, and Xpeng have outpaced foreign rivals with faster innovation cycles and more tailored software ecosystems.
Next-Gen EV Platform Anchored in Local Innovation
The upcoming chip will be embedded in Volkswagen’s third-generation EV technology platform, known as CEA (China Electrical Architecture). The company expects that by 2030, roughly 80% of its cars sold in China will be built using this architecture, signaling a decisive localization strategy.
Volkswagen’s deeper collaboration with Horizon Robotics allows it to bypass some of the constraints foreign automakers face in China’s tightly regulated semiconductor sector. The venture also complements Volkswagen’s 5% stake in Xpeng, with which it is co-developing smart vehicles for the Chinese market.
As competition intensifies, in-house chip design has become a defining strategy for automakers looking to differentiate their ADAS (advanced driver-assistance systems) and autonomous driving stacks. Chinese companies like Xpeng and Nio are already producing in-house smart-driving chips, narrowing the technology gap with global chip leaders.
Navigating Foundry Limits and Export Controls
However, Volkswagen’s ambition depends on more than design innovation, it hinges on foundry access and process node maturity within China. Current export restrictions on advanced lithography equipment limit domestic foundries’ ability to manufacture chips at cutting-edge nodes.
Horizon’s Journey 6 platform, which uses the Nash Brain Processing Unit (BPU) optimized for Transformer-based neural networks, currently peaks around 1,000 TOPS in ZF’s ProAI systems.
Achieving Volkswagen’s 500–700 TOPS range would require either a major architectural leap or collaboration with fabs capable of running more advanced nodes, both areas constrained by geopolitics.
Bridging the Software-Hardware Divide
For developers and investors alike, the collaboration signals an emerging race not only for hardware performance but also for software harmonization.
Horizon’s open SDKs and partnerships with Wind River and Aptiv enable cross-platform development, allowing Volkswagen’s future vehicles to run AI workloads on different SoC configurations.
That modularity could prove key to Volkswagen’s long-term success in China, where speed, adaptability, and localization are crucial for survival. As global automakers scramble to catch up with China’s AI-led vehicle revolution, Volkswagen’s chip venture underscores a strategic pivot, innovation built in China, for China.
