Rivian R2 Will Use Radar, Not Ultrasonic Sensors

Rivian is dropping the ultrasonic parking sensors found on the R1 and moving the upcoming R2 to a vision first setup at launch. Those bumper sensors normally handle close range object detection during parking and low speed maneuvers, so this is a notable shift. Instead, R2 will rely more heavily on cameras and radar, with LiDAR expected to join the hardware stack later in 2026. Here’s what those sensors actually do, what changes with vision only, and how Rivian’s broader autonomy roadmap plays into this decision.
