Rivian is rolling out RivianOS 2, the biggest overhaul of its in-car software since the R1 first shipped. For the first time, it puts every vehicle the company sells on a single software stack.
The update, version 2026.31, started reaching eligible R1 and R2 vehicles today. It brings a rebuilt interface, Unreal Engine 5 graphics, real-time police and speed-camera alerts, and a deeper AI layer Rivian calls Unified Intelligence.
One software stack across the whole lineup
Until now, first-generation R1s, second-generation R1s, and the new R2 ran on software that had drifted apart. RivianOS 2 pulls them back together onto one common foundation.
The hardware still sets limits. On the R2 and Gen 2 R1, Rivian is using Unreal Engine 5 for real-time 3D visualizations of the vehicle and its surroundings. Gen 1 R1s stay on Unreal Engine 4 to keep the screen responsive on older computing hardware. So “one stack” doesn’t mean one identical experience across the fleet, but it just got a lot closer.
