Rivian shipped an AI voice assistant this week that does what Tesla's Grok still cannot: control the vehicle.
Activated by saying "Hey Rivian" or holding the left steering wheel button, the assistant is rolling out to Gen 1 and Gen 2 R1S and R1T owners through the 2026.15 over-the-air software update. It requires an active Connect+ subscription, which costs $14.99 per month or $149.99 per year.
The key difference between Rivian's offering and Tesla's "Hey Grok" assistant, which launched in Tesla's Spring 2026 update, is hardware access. Rivian's assistant is built directly into the vehicle's electronic architecture, not layered on top of a phone-mirroring system. That means owners can change drive modes, adjust ride height, open the front trunk, tweak climate settings, and check range-on-arrival data, all hands-free. Tesla's Grok, months after its beta launch, still cannot control climate, media, or core vehicle functions.
Rivian first previewed the technology at its Autonomy and AI Day in December 2025, where it described the underlying system as "Rivian Unified Intelligence", a multi-modal AI framework combining custom large language models with an orchestration layer that understands both the vehicle's systems and the driver's personal context. The assistant is the first consumer-facing product from that AI push. The assistant handles the usual voice tasks, navigation, media, calling, messaging, but also pulls from the owner's manual for troubleshooting. Drivers can ask how to change a tire or what a dashboard alert means and get answers without digging through a PDF.
It can read incoming texts, summarize them, and draft natural-sounding responses. It answers general knowledge questions like any chatbot.
Multi-step commands are the headline feature. A driver could ask the assistant to find a coffee shop on the way to a meeting, send a friend the ETA, and adjust the passenger seat heating, all in one request. The assistant saves learned preferences to individual driver profiles, so settings don't bleed between users in the same household. The first third-party integration is Google Calendar, letting owners check schedules, move meetings, and combine calendar actions with navigation and messaging. Rivian told RivianTrackr that additional calendar integrations (Apple, Outlook) are coming in future updates.
Privacy controls let owners disable the "Hey Rivian" wake word, limit location sharing, and turn off the memory feature. Personal context stays within individual driver profiles and is off by default. The assistant is English-only for now. Enabling it automatically disables Alexa and its integrations. The R2, Rivian's mid-size electric SUV that started production recently, will ship with the assistant when customer deliveries begin in the coming weeks. The R2 platform delivers 200 sparse TOPS of edge AI compute, hardware built specifically for these capabilities.
Rivian expects to deliver the R2's most expensive variant later this spring, with the $45,000 base model following in 2027.
