The joint venture between Volkswagen Group and Rivian, known as Rivian Volkswagen Group Technologies (RV Tech), has completed winter testing of its software-defined vehicle (SDV) architecture, marking a milestone in the development of next-generation electric vehicles.
The multi-month testing programme took place in Phoenix and Arjeplog, involving teams from Volkswagen, Audi and Scout Motors. Reference vehicles used in the tests included the Volkswagen ID.EVERY1, alongside models from Audi and Scout.
According to Volkswagen, the tests validated both hardware and software performance under real-world and extreme conditions. Initial trials in Arizona focused on finalising software functions, while subsequent winter testing in northern Sweden assessed system reliability under harsh climates.
“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,” the company said.
The SDV architecture is intended to underpin a new generation of battery-electric vehicles across Western markets, enabling features such as highly automated driving and continuously updated infotainment systems via over-the-air updates.
“With the successful completion of the winter tests, our joint venture once again demonstrates the speed and precision of its work,” said Oliver Blume, Chief Executive Officer of Volkswagen Group. “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.”
Volkswagen added that the architecture will be deployed across multiple brands, while a parallel partnership with Xpeng is focused on the Chinese market.
The automaker also plans to strengthen internal software capabilities. From May, Volkswagen Passenger Cars will launch a training programme enabling software specialists to work at RV Tech locations, including in Palo Alto, before returning to integrate the technology into production vehicles. Similar initiatives are planned at Audi and Porsche.
While Volkswagen expressed confidence in the project’s progress, the joint venture comes amid broader industry pressure to accelerate software development. Rivian is simultaneously preparing for the launch of its next-generation models, including the R2, which is expected to play a key role in scaling production.
Volkswagen said the successful winter testing demonstrates that the SDV architecture is already capable of operating reliably under demanding conditions, laying the groundwork for further development and future vehicle integration.
