R2: Real-World Testing Begins

A behind-the-scenes look at R2 as progress continues

Our tour across Rivian continues on our way to bringing R2 to the world.

We continue our series on R2’s progress with our pilot manufacturing line, where we validate the parts and build process for R2, and our testing grounds, where we validate each and every aspect of the product. With design and engineering ready for production, the many components and subsystems of R2 have begun the final phase of real-world testing.

Pilot Line

Before the start of production next year, we’re making sure R2 is ready to build at global scale, from parts design to end of line processes. This starts with validating each individual part and how they all fit together. The assembly process is refined through validation builds on our pilot line in California. The team from our manufacturing plant in Normal, IL rotates in to train on the new processes while providing critical feedback to our engineers to make vehicle assembly as simple and efficient as possible. Pilot line testing ensures R2 will be built to the highest standard of quality from the very beginning.

Proving Grounds

From the pilot line, the first R2 validation builds head to our proving grounds and test facilities all over the country, where they undergo virtually nonstop testing for durability, dynamics and controls, software, ADAS and much more. These tests provide data on how the vehicle behaves under every conceivable condition—from normal mileage accumulation to extreme temperatures and driving scenarios. This creates an invaluable feedback loop for our engineers to fine-tune the product before production.
