Rivian launches ‘Hey Rivian’ AI assistant with full vehicle control

Rivian is now pushing its next-generation voice assistant to all Gen 1 and Gen 2 R1 owners as part of the latest over-the-air software update. Owners can trigger the system by saying “Hey Rivian” or pressing and holding the left steering wheel button, though an active Connect+ subscription is required.

What sets this assistant apart is its ability to control core vehicle functions , a capability that Tesla’s Grok assistant still lacks months after its own launch.

Built on Rivian Unified Intelligence

The Rivian Assistant is powered by what the company calls “Rivian Unified Intelligence,” a multi-modal AI framework that pairs custom large language models with an orchestration layer designed to grasp both the vehicle’s systems and the driver’s personal context.

Rivian first showcased the technology at its AI and Autonomy Day in December 2025, where it also revealed an in-house silicon chip and Level 4 self-driving ambitions. The assistant now stands as the first consumer-facing product from that AI initiative.

Unlike phone-mirroring systems such as Apple CarPlay’s Siri or Android Auto’s Google Assistant, the Rivian Assistant is embedded directly into the vehicle’s hardware and software. This gives it access to systems that phone-based assistants simply cannot reach.

What the assistant can do

Vehicle control is where this system truly distinguishes itself. Owners can change drive modes, adjust ride height, open the front trunk, modify climate settings, and check EV-specific data like range-on-arrival estimates , all hands-free.

Context-aware commands go beyond simple keyword matching. Rivian says the assistant understands natural language and complex context, enabling multi-parameter requests such as adjusting individual seat heating for specific passengers in a single sentence.

Navigation and media let you search for points of interest, get directions, and query information about currently playing media.

AI-powered messaging goes beyond basic dictation. The system can read incoming texts, summarize them, and help draft responses that Rivian claims will sound natural rather than robotic.

Vehicle knowledge means the assistant is trained on the owner’s manual, so it can answer troubleshooting questions about tires, features, and vehicle systems.

The assistant also handles general knowledge queries, including real-time weather and local news.

Agentic integrations starting with Google Calendar

Rivian describes its assistant as having an “agentic framework,” meaning it can chain multiple actions together across different services. The first third-party integration is Google Calendar.

Owners can ask the assistant to check their schedule, move meetings, and combine calendar actions with navigation and messaging in a single flow. For example, you could ask it to find a coffee shop on the way to your next appointment and text your contact an ETA.

The company says more third-party integrations are coming, though it hasn’t specified which services are next.

The Tesla comparison is unavoidable

Tesla launched its own “Hey Grok” voice assistant in its Spring 2026 update, powered by xAI’s Grok model. On paper, the two features sound similar. In practice, they are not.

Tesla’s Grok can handle navigation commands, answer general knowledge questions, and look up information from the vehicle’s manual. But critically, Grok still cannot control climate, media, or other core vehicle functions , a limitation that has been well-documented since its beta launch. Meanwhile, Mercedes-Benz’s MBUX voice assistant has offered full vehicle control for years.

Rivian’s assistant launches with native control over drive modes, climate, ride height, the front trunk, cameras, and range data. That is a meaningful gap.

The assistant requires Connect+, which costs $14.99 per month or $149.99 per year. Tesla’s Grok requires Premium Connectivity. Both are subscription-gated, but Rivian delivers more vehicle-integrated functionality for a lower monthly price.

The assistant will also be available on the R2 when it begins customer deliveries in the coming weeks, as the new platform delivers 200 sparse TOPS of edge AI compute , hardware purpose-built for these capabilities.

Privacy controls

Rivian includes controls that let owners toggle off the “Hey Rivian” wake word, limit location sharing, and disable the memory feature. Personal context the assistant learns is saved to individual driver profiles, not shared across users.

The feature is available in English only and requires a cloud connection.

Electrek’s Take

Rivian is executing an impressive software strategy, and the assistant launch is the latest proof point. As the company reported in its Q4 2025 earnings, software-driven revenue growth is becoming a real part of the Rivian story, and features like this give Connect+ subscribers a tangible reason to keep paying.

The competitive contrast with Tesla is striking. Rivian launched a voice assistant that controls the vehicle from day one. Tesla launched Grok months ago and it still cannot adjust your climate or change a song. That’s not a minor gap , vehicle control is the entire reason you’d want a car-native assistant instead of just talking to your phone.

We should note that the “agentic” framing , chaining calendar, navigation, and messaging together , is genuinely useful if it works reliably. The question is execution. Voice assistants across the auto industry have a long history of promising natural language understanding and delivering frustration. Rivian will be judged on how well these multi-step flows actually work in the real world, not on a blog post.

Still, on paper, this is already one of the most capable voice assistants shipping in any EV right now. If Rivian can match the promise with consistent real-world performance, it becomes another strong differentiator as the R2 heads to market.
