Volkswagen weights XPeng co-developed architecture to European models

China-engineered technology could cut development spending by billions, accelerate vehicle launches and reshape the group’s software strategy

Volkswagen Group is reportedly considering introducing the CEA (China Electronic Architecture), an electrical and electronic (E/E) architecture co-developed with XPeng, to Europe, potentially expanding the role of China-developed technology across its global lineup and covering its three core brands: Volkswagen, Skoda and Cupra, according to German business magazine Manager Magazin, citing people familiar with the matter.

Volkswagen core brand CEO Thomas Schäfer is expected to present the proposal to the group’s management on October 27, local time, according to the report. The plan, submitted for review by Schäfer in his capacity as head of the Core brand group, would cover approximately 75% of next-generation models across the three brands.

If implemented, the proposal would alter Volkswagen's strategy of developing separate software technologies for China and Western markets.

Volkswagen has so far pursued separate technology strategies for China and Europe. In China, it uses the CEA architecture developed jointly with XPeng.

In Europe and other Western markets, the group has primarily relied on a software technology platform developed through its joint venture with Rivian. In 2024, Volkswagen announced an investment of up to $5.8 billion in Rivian. 

The partnership is also a key part of Group CEO Oliver Blume’s efforts to transform the automaker’s software business.

Cost reduction is a major factor behind the proposed shift. CEA uses a zonal architecture that consolidates distributed electronic control units (ECUs), reducing the number of controllers installed in a vehicle.

The architecture is reported to cut the number of ECUs by approximately 30% and improve vehicle development efficiency by up to 30%. 

Development costs for selected key new models could fall by as much as 50%, while development cycles could be shortened to around 18 months.

German experts estimate that extending the architecture to more models could reduce Volkswagen’s development spending by €4 billion to €5 billion ($4.6 billion to $5.8 billion), according to Manager Magazin.

Potential applications cited in the report include future electric models such as the ID. Golf, ID. Passat and Skoda Enyaq. The mainstream segments these vehicles compete in are particularly sensitive to development costs and pricing competitiveness.

Supporters of the proposal argue that the software and electrical/electronic architecture developed by the Chinese team are already in use and can also support vehicles built on the group's existing European platforms, the magazine reported.

Volkswagen's strategic partnership with XPeng began in July 2023, when the German automaker announced a $700 million investment in the Chinese company and plans to jointly develop 2 Volkswagen-branded battery electric models for China.

In August 2025, the companies expanded their cooperation, extending the jointly developed electrical/electronic architecture (E/E Architecture) beyond battery electric platforms to Volkswagen's internal combustion engine and plug-in hybrid platforms in China.

The first model equipped with CEA, the ID. UNYX 07, began production at Volkswagen Anhui’s plant in January 2026. 

XPeng's in-house developed E/E architecture is at the core of its vertically integrated, full-stack hardware and software technology, which allows software including ADAS (Advanced Driver Assistance System) and Connectivity OS to be decoupled from the underlying hardware and vehicle platforms, enabling rapid iteration of cross-platform software, the statement said.

The latest generation of XPeng's E/E architecture utilizes a central computing and domain controller-based architecture to provide a high-performance in-vehicle computing environment and a competitive cost structure, according to the statement.

The E/E architecture supports Gigabit Ethernet high-speed data transfers between the central domain and ADAS domain controllers, XPeng said.
