GM debuts Gemini-powered OnStar AI in 2027 Cadillac Lyriq

GM is debuting its new in-car assistant, OnStar AI, in the 2027 Cadillac Lyriq through an over-the-air software update in the coming months, with the Chevrolet Silverado 1500 and GMC Sierra 1500 next in line. The pitch, as Wired reported, is less a smarter voice command than a car that runs errands for you.

The assistant is powered by Google Gemini, extending a GM-Google partnership that dates to 2019. Drivers trigger it with 'Hey, OnStar,' and it has access to real-time vehicle data such as tire pressure, charging status and projected range. It can also control the dome lights, electronic glove box and charge port, and help plan charging stops.

The strategic ambition sits with Sterling Anderson, GM's Chief Product Officer, who frames the car as a productivity surface rather than a cockpit. He told Wired the company wants to 'make it more productive, make it more relaxing, make it more engaging' and 'make your vehicle a more central, more useful part of your life than it has been historically.' Anderson also sketched a future where the assistant could eventually coordinate children's pickups and drop-offs based on which spouse's car is closer, presenting that as a direction of travel rather than a confirmed feature of the first release.

Alongside the assistant, GM is collapsing its app sprawl. A unified OnStar mobile app arriving in 2027 will replace the OnStar Guardian app and the separate Buick, Cadillac, Chevrolet, and GMC apps. OnStar AI will be sold as a subscription, slotting it into a crowded in-car AI market that already includes Gemini on Android Auto and voice stacks from most major automakers.

Human OnStar advisors will still take over when airbags deploy.
