No, it runs only on hydrogen (to EV direct drive). https://m.hyundaiusa.com/nexo/. Zero emissions, refuels in five minutes at one of California's 40 stations. Soon all hydrogen production will be renewable from solar and wind electrolysis. Exciting times.
It's the hydrogen that makes it a hybrid. The parent comment is correct. Being a hybrid does not require eg a gasoline motor. It's not strictly an electric vehicle, it requires hydrogen in the process.
Their own diagram is very clear about this matter: motor + fuel cell + hydrogen + battery.
That's not the common definition of hybrid. Here, electricity directly powers an electric motor and there are no emissions. Is a Tesla a hybrid because some of its electricity comes from regenerative breaking? How about if some comes from from ions in an electrolyte solution?
I think you're overthinking it. Hybrid cars are not bad, they are pretty cool. It's a matter of semantics. A hydrogen fuel cell car could be considered a hybrid because the primary source of energy, hydrogen, is converted into energy and stored into an electric battery, which powers the drivetrain. Zero emissions, no internal combustion engine, hydrogen-electric hybrid.
Tesla is pure electric. You charge the battery itself, directly.
