General Motors is gearing up to bring a new era of intelligent driving to its customers. Beginning next year, the automaker will introduce a conversational AI assistant powered by Google Gemini across its cars, trucks, and SUVs. The announcement was made during the company’s GM Forward event in New York City, where several technology-driven initiatives were revealed.
While GM outlined long-term plans for a revamped electrical architecture and a fully automated driving feature set for 2028, the Gemini rollout stands out as a near-term leap in how drivers will interact with their vehicles.
Driving Meets Conversation
The Gemini AI assistant represents GM’s next major step in integrating artificial intelligence into its driving experience. Vehicles from Buick, Chevrolet, Cadillac, and GMC already operate on “Google built-in” systems that feature Google Assistant, Maps, and Play Store apps. The new Gemini integration builds upon this foundation, offering a more natural, human-like conversational experience.
“One of the biggest frustrations with traditional voice assistants is their rigidity,” said Dave Richardson, GM’s Senior Vice President of Software and Services. “They depend on specific commands and often fail to understand accents or natural phrasing. Large language models like Gemini solve that—they remember context, adapt to tone, and make interactions feel seamless.”
From drafting messages and finding nearby stops to preparing for a meeting on the go, the Gemini-powered assistant will make everyday driving tasks simpler. It will even be able to answer contextual questions like, “What’s the history of this bridge?” using live internet access.
Expanding OnStar’s Capabilities
The Gemini assistant will be distributed as an over-the-air upgrade via the Play Store to all OnStar-equipped GM vehicles from model year 2015 and above. This marks one of the most extensive post-sale technology upgrades GM has ever undertaken.
More than a digital concierge, the AI will connect with vehicle data systems to deliver personalized insights and assistance from maintenance alerts and feature explanations to climate control activation before entry. In essence, it turns the vehicle into an intelligent companion that learns from the driver’s habits.
“The vision is to take a general-purpose language model and refine it with GM’s own data,” Richardson explained. “By training it on vehicle-specific systems, we’ll distill that intelligence to operate locally in the car.”
Privacy by Design
Introducing a data-connected AI inevitably raises privacy questions, especially after GM faced criticism earlier this year for sharing driving and location data with insurance companies. Richardson addressed this head-on, emphasizing that data control will rest with the driver.
“Every action will be consent-driven,” he said. “Drivers can opt in or out of what information the assistant accesses. Our approach is simple: privacy and transparency must be built into every layer of our work.”
To strengthen that stance, GM has built a new data governance team led by Christina Montgomery, former Chief Privacy and Trust Officer at IBM.
A Broader AI Ecosystem
While Google remains a key partner, GM isn’t locking itself in. The company plans to test multiple foundational AI models, including those from OpenAI, Anthropic, and others. The goal, according to Richardson, is to develop GM’s own proprietary AI platform, one that integrates deeply with OnStar and its vehicle ecosystem.
As automakers race to make driving more connected, intuitive, and personalized, GM’s move to embed conversational AI directly into vehicles signals a clear direction: the car of the future won’t just drive itself — it’ll talk, learn, and adapt to the driver who owns it.
