why electromagnets aren’t used in piston motors, including internal combustion or not including internal combustion

Question

Will pistons specifically in the cylinder ever use electromagnets to propel the piston and to spin the driveshaft like gasoline motors?

Answer 1

Gas has way more energy per weight than batteries. Since we need combustion to extract energy from gas, pistons are the easiest design to utilize that. Introducing electromagnets would just add unnecessary power loss.

That said, we do have electric cars nowadays! Not nearly as much range as a gas vehicle of equivalent weight, but they certainly have their pros
