When a headline like this says first I think it either means first test vehicle and it’ll be years before it’s available to the public or first brand, which is what I’d rather be hearing about. Article starts off saying “the first mass-produced electric vehicle (EV) with a sodium-ion battery”. If they buried that I’d say it was a clickbait headline but this way it seems pretty up front they’re just shortening for length. In my opinion. 🙂
