I watch a tv program, where they investigate RUMORS, to see if there is any truth to them.
One particular Rumor involves EVs ..
The rumor states that AM radio in Vehicles will be eliminated:
one assumption was that Pressure was being put on Radio Station Operators, to get rid of Radio Shows that had a Political Only subject.
That was tossed in the trash bucket.
Then they had a more correct answer ...
AM Radio will not be installed in Electric Vehicles, because it draws off too much Battery Power.
I think it is funny that only AM radio was mentioned,
What about FM or Satellite radio ?
Don't they draw just as much power ??
Don't trust that tv show, whatever it is. AM drawing a significant amount of power over FM is laughably wrong. An antenna doesn't use electrical power, it receives it. Frequency doesn't change that. How much power your radio uses is pretty much whatever it's using to drive the speakers and light up the display. (there are signal amplifiers that use power to increase the signal the antennae passively receives, but no need to get that far in to the weeds on this)
The assumption it's some political thing is also wrong, given the US Congress introduced legislation to make auto makers keep installing AM radio due to emergency broadcast requirements. See:

For EV's, it's pretty simple. EVs have big ol' electric motors that create larger amounts of radio interference in the same band as AM Radio uses. Not about power consumption, just the "bleed over", so to speak, will make AM suck. Sort of like when you had a bad ground and you'd get alternator whine through your stereo, just there's nothing to ground to make it stop. For all vehicles, regardless of power train, it's the same reason they don't put in 8-track players, cassette players, CD players, etc. any longer. To do so cost money, customers don't value it enough to pay extra for it, so the economic incentive is to leave it out.
