Volkswagen is reportedly considering equipping up to 75% of its future European mainstream models with electronic architecture developed in China alongside Xpeng.

The move could save billions of euros but threaten its expensive partnership with American EV maker Rivian. It also raises questions about European homologation, cybersecurity, and the growing dependence of European carmakers on Chinese technology.

According to Germany’s Manager Magazin, Volkswagen brand CEO Thomas Schäfer and China board member Ralf Brandstätter want to introduce the China Electronic Architecture (CEA) into future European models from Volkswagen, Škoda, and Cupra.

The proposal, reportedly discussed at management level this week, could cover approximately three-quarters of the brands’ next-generation models. Potential candidates include the future ID. Golf, ID. Passat, and Škoda Enyaq. Volkswagen declined to comment on the reports, which have also been carried by Reuters.

Up to €5 billion in savings

The financial incentives are considerable. Internal estimates suggest that adopting the Chinese-developed architecture could save Volkswagen between €4 billion and €5 billion in development costs.

The technology is already operational. Developed jointly by Volkswagen Group China Technology Company, CARIAD China, and Chinese EV manufacturer Xpeng, the China Electronic Architecture (CEA) entered series production in January 2026 with the Volkswagen ID. UNYX 07.

It serves as the car’s digital backbone, replacing numerous separate electronic control units with centralized computing and zonal controllers.

This reduces the complexity of the vehicle’s electrical system, potentially eliminating substantial wiring lengths and saving weight and costs, while enabling more efficient communication and over-the-air software updates. Volkswagen claims the architecture reduces the number of electronic control units by approximately 30%.

The architecture took just 18 months to develop and industrialize, a record for Volkswagen. It can support electric, hybrid, and combustion-engine vehicles. For a manufacturer struggling with software delays and mounting development costs, the attraction is obvious.

What about Rivian?

However, adopting the CEA in Europe would challenge another cornerstone of Volkswagen’s software strategy: its $5.8 billion partnership with American EV manufacturer Rivian.

Until now, Volkswagen has pursued separate approaches: Chinese-developed electronics for China and a new architecture developed with Rivian for Western markets.

Shifting high-volume European models to the CEA could undermine the economics of the Rivian venture. Premium brands such as Audi and Porsche might continue to use American technology, but fewer vehicles would remain to share in its development costs.

According to Electrive, the proposal is encountering internal resistance, particularly over its implications for Rivian and the potential costs of adapting Chinese technology to European requirements.

European approval is not automatic

There is no general European prohibition on Chinese-developed automotive electronics. However, using the CEA in China does not automatically qualify it for installation in European vehicles.

Volkswagen would have to satisfy European type-approval requirements, including UNECE Regulation R155 on automotive cybersecurity and R156 governing software updates.

These regulations require manufacturers to demonstrate adequate protection against cyberattacks, manage software vulnerabilities, and maintain secure, traceable update procedures.

European rules on vehicle safety and data protection introduce further requirements. Connected services handling personal information, including location data, must comply with the GDPR.

Importantly, an electronic architecture is not necessarily a complete operating system. Volkswagen could use the Chinese-developed hardware and software foundations while retaining European control over applications, connected services, and security infrastructure.

But such adaptations require engineering, validation, and certification. They could erode part of the projected savings.

Could Volkswagen cars become Chinese spying devices?

The security concerns extend beyond conventional hacking. Modern connected vehicles continuously generate information about their surroundings, movements, occupants, and sometimes sensitive locations.

German broadcasters NDR and WDR reported in February that German security authorities had investigated potential espionage risks associated with connected Chinese vehicles. Their findings were not publicly disclosed.

There is, however, no publicly substantiated evidence that Volkswagen’s CEA contains espionage functionality or provides Chinese authorities with access to vehicle data.

The relevant questions concern who controls the software, cloud infrastructure, encryption keys, remote updates, and access to collected data.

The United States has already adopted restrictions on certain connected-vehicle software and hardware linked to China or Russia, with software restrictions taking effect in model-year 2027 vehicles.

Europe currently relies primarily on cybersecurity, type-approval, and data-protection requirements rather than an equivalent general ban.

The technology flow reverses

Beyond Volkswagen, the implications are significant. Stellantis is already pursuing a comparable strategy with China’s Leapmotor.

Opel is developing a new electric C-segment SUV for a potential 2028 launch, using Leapmotor’s electronic architecture, batteries, and electric powertrain, while retaining responsibility for chassis, steering, design, and user experience.

The model is intended to be manufactured in Zaragoza, Spain, alongside the Leapmotor B10. Like Volkswagen’s proposed Xpeng-based architecture, the project illustrates how European manufacturers are increasingly looking to China not merely for cheaper components, but for the digital foundations of their future cars.

For decades, European manufacturers transferred vehicle technology to Chinese joint ventures. Increasingly, the flow of technology could move in the opposite direction.

Volkswagen’s dilemma illustrates the changing balance of power. Chinese manufacturers are no longer merely competing on battery costs and vehicle prices. Their advantages increasingly include electronic architectures, software development speed, and integration.

For Europe’s car industry, the central question is whether adopting cheaper Chinese technology can preserve competitiveness without sacrificing control over the digital systems that increasingly define the modern automobile.
