I could have sworn either the Abrams X or the Black Panther have an optional electric only mode, with onboard batteries that charge from the main engine, to allow either a moderate ability to move significantly more quietly or basically idle/hunker down at near silence.

While a tank being moved by a batteries is still quite loud up close, not using the incredibly loud engines would make it harder to hear from a decent distance away and could have legitimate tactical uses.

Also apparently Ola has made and will be selling a 120mph capable fully electric motorcycle in SE Asia: https://www.olaelectric.com/motorcycles
