Most Americans get into their cars and pop on a podcast or stream some music. Some may not even know that century-old AM radio is disappearing from vehicles. Well, not for long, perhaps. 

Lawmakers in Congress are demanding that automakers bring the tuner back to new cars, and the House officially passed the AM Radio for Every Vehicle act this week. If adopted into law, it would force brands to equip every new vehicle sold in the U.S. with an AM tuner at no extra cost—even if those cars are electric. 

You might be wondering why we even mention powertrain here.
