Well, here’s an unexpected combination… Toyota’s Toyota Connected North America unit is developing a console-grade open-source game engine. Making it even more unusual is their engineering choices of building around the Flutter toolkit and in turn the Dart programming language. This new game engine creation is called Fluorite.
Toyota Connected North America is Toyota Motor Corporation’s subsidiary founded in collaboration with Microsoft for working on in-vehicle software, AI, and related tech initiatives. Toyota Connected developers announced at FOSDEM 2026 their Fluorite game engine as a “console grade” engine built around Flutter and Dart. They were going with Flutter to leverage its rich UI toolkit and for “building stunning interactive experiences.” Fluorite also makes use of Google’s Filament 3D rendering engine.
Toyota’s in-vehicle home screen already has an embedded Flutter run-time with Yocto Linux and Wayland. That is used in production on some of their vehicles like the Toyota RAV4 2026.
Toyota is interested in a game engine suited for their in-vehicle / digital cockpit experience. Options like Unity and Unreal Engine were rejected due to proprietary blobs, resource weight, and licensing fees. Meanwhile for Godot they found long start-up times and being too resource heavy. Other options were found to be unstable or lacking a stable API.
With Fluorite they are leveraging Filament, SDL, and other well known options and relying on the Dart programming language code for both UI and game logic handling. They also have plans to integrate Jolt Physics.
Those wishing to learn more about Fluorite can watch the FOSDEM 2026 presentation on this open-source game engine via FOSDEM.org. The presentation does cite fluorite.game as their website where they further detail this “first console-grade game engine fully integrated with Flutter.” Details there are light — as well as the lack of any source repository noted — but more is “coming soon”.
