Rivian-Volkswagen joint venture completes SDV architecture winter testing

The Rivian and Volkswagen Group Technologies (RV Tech) joint venture has completed winter testing of its production-intent zonal architecture for the first generation of software‑defined vehicles (SDVs). Over the course of several months of testing in Phoenix, Arizona, and Arjeplog, Sweden, a joint team from Volkswagen, Audi, Scout and RV Tech validated the functionality and performance of the electronics and software.

The partnership is developing SDV technology, from operating systems to zonal controllers to cloud and connectivity solutions.

Oliver Blume, CEO of the Volkswagen Group, said, “We are accelerating toward the future. With the successful completion of the winter tests, our joint venture once again demonstrates the speed and precision of its work. The close integration between the joint venture, our brands and the group follows a clear objective: to excite people with products and technologies that set new standards. This is how we are driving development forward across the Volkswagen Group – with the ambition to become the global automotive tech driver.”

Winter endurance testing

The program consisted of two phases. In Arizona, engineering teams from the brands and the joint venture worked together to finalize key software functions and prepare the reference vehicles for the winter tests in Europe. In Sweden, the systems were then subjected to stress testing under extreme weather conditions with snow and ice. The teams examined, among other things, the interaction between hardware and software for functions such as all-wheel drive, traction control and driving performance. Over-the-air (OTA) functionality was also validated. In total, the joint venture and brands conducted hundreds of tests and validation cycles. Individual approval drives in Germany and Sweden, led by the brands’ development teams, marked the completion of the winter testing program.

The results show the SDV architecture operates reliably in harsh winter and dynamic driving conditions. This milestone also lays the foundation for the next development phases across the joint venture and individual group brands. The Volkswagen Group will deploy this SDV architecture in electric vehicles across Western Hemisphere markets, delivering highly automated driving features and advanced infotainment, with continuous updates delivered over the air.

Qualification program

In parallel, the Volkswagen Group brands are strengthening their software capabilities for the SDV. Volkswagen Passenger Cars is expected to rapidly launch a long‑planned qualification program at the beginning of May where software specialists will spend several months at RV Tech locations, including Palo Alto, California, to deepen their knowledge of the joint venture’s architecture and code. Upon returning to Wolfsburg, these specialists will serve as internal experts and bring this expertise back into their development departments as multipliers. This will help to integrate brand-specific functions more quickly into future production models. Audi and Porsche are also preparing to launch similar training programs.
