Rivian Q4 2025: R2 On Track, Software Surges

R2 Validation Build

Rivian’s Q4 2025 shareholder letter makes one thing clear, R2 is the pivot point. With manufacturing validation builds complete and deliveries still targeted for Q2 2026, Rivian is preparing for its biggest launch yet. At the same time, autonomy hardware, in house silicon, and surging software revenue are starting to reshape the company’s financial story as it pushes toward scale.

Real World Data Shows Rivian R1S Dual Standard LFP Range Gap vs EPA

R1S Dual Standard

A Gen 2 Rivian R1S Dual Standard owner equipped with the LFP battery and 20" AllsSeason wheels, rated at 258 miles EPA, shared real world winter data showing dramatically lower range. With efficiency of 1.35 mi/kWh and just 115 miles displayed at 85%, the numbers raise fresh questions about ongoing calibration and cold weather impact.

Rivian R2 Will Use Radar, Not Ultrasonic Sensors

R2 Validation Builds

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.

Rivian Explains R2 Electronic Door Latches After Concerns

Rivian R2 Silver Prototype

Rivian’s software chief, Wassym Bensaid, jumped into Reddit to address growing concerns around the electronic door latches coming to R2 and already used on Gen 2 R1. He explained that Rivian designed the system with full power redundancy between the high voltage and 12V batteries, ensuring the doors remain operational in a crash. More importantly, the e latch setup allows the vehicle to automatically release child locks and unlock doors after a collision, something traditional mechanical systems cannot do. Rivian says this move is about smarter, software driven safety, not cost cutting.
