Firefly updated its in-car software via OTA update recently, adding features like Nintendo Switch casting and customizable lock and unlock sounds and animations.

The Nintendo Switch streaming comes via a USB capture card, and a physical connection to the car.

Firefly's game casting feature works with both generations of the Nintendo Switch.

Too many cars available in the U.S. take themselves too seriously. Luckily, elsewhere in the world, more whimsical minds have prevailed. While in China last month, I got some seat time with the Firefly, a cutesy little hatchback from Nio’s sub-brand of the same name. I’ve driven the Firefly before; it's still great, especially with its retuned suspension and steering. But for 2026, the car has gotten an updated software system too, with some playful features you can’t find almost anywhere else.

Nio sees the Firefly as a car for young people. To lean into that, the brand has added the ability to cast games to the car’s central infotainment screen, via your Nintendo Switch. Eat your heart out, Sony Afeela. That car wowed journalists in 2024 with its ability to stream PlayStation 5 games on its massive screen. But the project will never see the light of day. Sony planned to use its PS Remote Play service to stream games to the car from a running PS5, which could be miles away in a driver’s living room.
