NXP’s S32K5 Microcontrollers Selected for Rivian-Volkswagen Joint Venture Vehicle Architecture, First Model Set for 2027 in Germany

Volkswagen Group and NXP Semiconductors have entered a strategic partnership under which NXP will supply microcontrollers for the Group's future zonal software-defined vehicle architecture.

The agreement was announced ahead of the International Suppliers Fair (IZB) in Wolfsburg and extends the two companies' existing cooperation in automotive semiconductor technology.

NXP microcontrollers to support shared SDV architecture

NXP is described as one of the world's leading automotive semiconductor companies. At the heart of the deal sits the NXP S32K5 family of microcontrollers, which will serve as an important building block of Volkswagen Group's software-defined vehicle (SDV) architecture, supporting zonal control across all brands and vehicle segments.

The first vehicle featuring the new architecture is planned for 2027. The MCUs are intended to act as a common building block for the zonal SDV architecture being developed by Rivian and Volkswagen Group Technologies, LLC (RV Tech), the joint venture between Volkswagen Group and Rivian.

That architecture is meant to be used across both companies' vehicles, while still enabling brand-specific features and experiences.

Why fewer ECUs matter

The move responds to a growing challenge in vehicle electronics. As modern cars must support an increasing number of digital functions, managing them through separate electronic control units (ECUs) raises complexity in development and parts management and restricts scalability. Zonal architecture tackles this by using powerful microcontrollers to consolidate multiple vehicle functions into fewer ECUs.

In this setup, high-performance processors provide the central computing power and make complex decisions for AI-enabled functions such as automated driving and advanced infotainment. Alongside them, the S32K5 MCUs act as the core processors of the vehicle's zonal controllers: they connect sensors and actuators, collect and process data from specific areas of the vehicle, and manage functions including lighting, body, comfort, chassis, and safety systems.

According to the companies, these capabilities form the foundation for the central computing platform to run AI algorithms and perform advanced functions. Because the S32K5 MCUs allow functions that previously required separate chips and ECUs to be folded into zonal controllers, hardware complexity is reduced.

NXP states the family is built for safe real-time compute, fast and secure over-the-air updates, and the consolidation of functions that together create the basis for a flexible, continuously updateable vehicle.

Part of a wider chip strategy

The partnership sits within Volkswagen Group's broader semiconductor strategy. Through direct, long-term partnerships with leading semiconductor companies, the Group seeks to combine its automotive expertise with chip technology, strengthen supply resilience, and jointly shape key technologies for future vehicle generations.

The approach supports the Group Target Picture 2030 and aims to leverage synergies across brands and regions while harmonizing key technologies.

What the executives said

Karsten Schnake, Member of the Extended Executive Committee and Member of the Volkswagen Brand Board of Management responsible for Procurement, said, "Semiconductors are strategic technology for the automotive industry. Over the past years, we have systematically expanded our technology ecosystem and built partnerships with leading companies across the value chain. 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."

Werner Tietz, Member of the Extended Volkswagen Group Executive Committee responsible for Group Research and Development, said, "Our future zonal architecture, developed by RV Tech and supported by strategic technology partners such as NXP, creates a scalable technology foundation for multiple Group brands and vehicle segments. By harmonizing key technologies across the Group, we reduce complexity, leverage scale, and accelerate innovation while enabling advanced digital capabilities. This allows us to bring digital innovations to our customers faster and continuously enhance our vehicles throughout their lifecycle."

Rafael Sotomayor, President and CEO at NXP Semiconductors, said, "Intelligent, software-defined vehicles must operate safely, securely, and reliably. Together with Volkswagen Group and RV Tech, NXP is bringing scalable real-time compute, trusted edge intelligence and continuous software innovation together to create a scalable foundation for the next generation of intelligent vehicles."

Lars Reger, Executive Vice President and CTO at NXP Semiconductors, said, "Software-defined differentiation is the new auto benchmark, and NXP is excited that the S32K5 family of MCUs has been adopted into RV Tech's innovative new zonal architecture, one of the most sophisticated approaches to streamlined development and differentiating features in the automotive industry today. As a core processor for the vehicle's zonal controllers, S32K5 is built for safe real-time compute, fast and secure OTA updates and the consolidation of functions that together create a basis for a flexible, continuously updateable vehicle."

Toward the 2027 launch

With the S32K5 MCU family adopted into RV Tech's zonal architecture, the partnership positions common MCU technology as a way to reduce complexity and support scalable deployment across brands and vehicle segments.

The first vehicle featuring the new architecture remains planned for 2027, and both companies frame the cooperation as a step toward a flexible, continuously updateable vehicle built on harmonized key technologies.
