NXP’s S32K5 microcontrollers will be a common building block for the zonal architecture VW and Rivian are developing via RV Tech
Volkswagen Group has chosen NXP’s S32K5 microcontrollers as a common building block for the zonal architecture it is developing with Rivian, the latest step in its push to deal directly with chipmakers. The first vehicle using the architecture is due in 2027.
In the zonal setup, the S32K5 chips act as the core processors of zonal controllers. They connect sensors and actuators and manage lighting, body, comfort, chassis and safety functions, while high-performance central processors handle automated driving and infotainment. The architecture comes from RV Tech, the Volkswagen-Rivian joint venture, and will be used in both companies’ vehicles.
“Our partnership with NXP is another step in this journey, showing how Volkswagen Group is taking a more active role in the semiconductor value chain: defining our technology needs early, leveraging our scale across brands and creating greater long-term planning certainty for both sides,” said Karsten Schnake, Member of the Volkswagen Brand Board of Management responsible for Procurement.
Direct chipmaker partnerships, a lesson of the post-pandemic shortages, are now standard across the industry, as Hyundai Mobis’s localisation push this week also shows. Standardising on one MCU family across brands gives Volkswagen volume leverage that individual brands would lack. It also puts more weight on RV Tech to deliver the software-defined platform that Cariad struggled to build.
Why this matters:
- OEMs go direct to chipmakers. Specifying MCUs and partnering directly with NXP shows Volkswagen taking control of semiconductor choices once left to Tier 1 suppliers, which could narrow the role of traditional ECU makers in zonal architectures.
- Resilience after Nexperia. Choosing a European chip partner follows the 2025 Nexperia export disruption that threatened Volkswagen’s production, though NXP’s advanced automotive chips still rely partly on Asian foundries.
- One building block, two automakers. A common MCU across Volkswagen brands and Rivian strengthens RV Tech’s scale case, and the first vehicle on the architecture in 2027 will test whether those savings hold at entry-level price points.
