The Future of Transportation is Here: Rivian and Arm Redefine Autonomous Driving
December 11, 2025 By Drew Henry, Executive Vice President, Physical AI Business Unit, Arm
Imagine a world where cars don't just drive themselves, but think and adapt like living beings. This isn't science fiction; it's the reality being forged by Rivian and Arm. Today, Rivian, a pioneer in AI-driven automotive technology, unveiled its groundbreaking third-generation autonomy hardware platform, the Rivian Gen 3 Autonomy Computer. But here's where it gets controversial: at the heart of this revolution lies a custom chip, the Rivian Autonomy Processor (RAP1), developed in partnership with Arm, a company traditionally associated with mobile devices. This unexpected alliance raises questions: Can a chip designed for smartphones truly power the future of autonomous vehicles?
The Rise of Physical AI: Beyond the Screen
AI is no longer confined to our screens. It's stepping into the physical world, powering robots, drones, and, most notably, self-driving cars. These machines need to perceive their surroundings, make split-second decisions, and act with unwavering reliability. This demands a new breed of computing power – one that's not only powerful but also efficient and inherently safe. This is the multi-trillion-dollar opportunity of physical AI, and Arm believes its compute platform, built on the cutting-edge Armv9 architecture, holds the key.
Rivian's Autonomy Breakthrough: A Chip Designed for the Road
Rivian's RAP1 chip, built on Armv9, is a testament to this vision. It's not just about processing power; it's about intelligent perception, real-time decision-making, and unwavering safety. The Arm Cortex-A720AE CPU, a v9 design, acts as the brain, interpreting the environment, predicting future scenarios, and choosing the safest course of action in milliseconds.
Safety First: A Pipeline of Trust
And this is the part most people miss: safety isn't an afterthought in Rivian's system. It's woven into the very fabric of the compute pipeline. Dedicated Arm processors handle real-time safety functions, ensuring consistent and reliable operation, even in the most unpredictable situations. This level of safety is crucial for any autonomous machine navigating the complexities of the real world.
Efficiency Meets Power: The Edge Advantage
Arm's compute platform delivers exceptional performance while sipping power, a crucial advantage as AI moves closer to the edge, directly into vehicles and other autonomous machines. This efficiency translates to extended range and improved overall performance, essential for the widespread adoption of autonomous technology.
Shaping the Future, Together
Rivian's third-generation autonomy platform is a powerful demonstration of how deeply integrated AI is transforming transportation. Intelligence, safety, and efficient computing are the cornerstones of physical AI's real-world applications. Arm's compute platform, powered by Armv9, is a driving force behind this transformation, enabling the perception, planning, and control capabilities that will define tomorrow's autonomous systems.
With partnerships like Rivian, Arm is at the forefront of this revolution. As we move towards a multi-trillion-dollar physical AI economy encompassing mobility, robotics, logistics, and industrial automation, Arm is providing the intelligent, efficient, and safety-focused compute foundation that will empower innovators to build the machines of the future.
