AM radio is underneath the gun, with an increasing number of automakers discontinuing its use, particularly because the business undergoes a speedy shift to electrification. Lawmakers and regulators are nervous that the gradual demise of AM radio might make it tougher to broadcast emergency data throughout a pure catastrophe or different associated occasions. However automakers are undeterred and appear decided to brush AM radio into the dustbin of historical past.
The most recent mannequin to hit dealerships with out the first-generation radio broadcast expertise is the 2024 Ford Mustang, in response to Ars Technica, citing Ford Authority. Certainly, Ford was certainly one of eight firms to primarily declare AM radio to be an out of date expertise of their response to Senator Ed Markey’s (D-MA) request for data.

Ford was joined by BMW, Mazda, Polestar, Rivian, Tesla, Volkswagen, and Volvo in staking out the place that AM radio is incompatible with EVs, citing electromagnetic interference from the powertrain. Certainly, Tesla made this identical argument when it eliminated AM radio from its automobiles again in 2018.
Based on a Vice article from 2016, the issue is when the interference will get picked up by the radio:
EVs are powered by a chargeable battery, electrical motor, and a frequency converter that controls how a lot energy the automotive’s electrical motors put out by turning voltage on and off 1000’s of occasions a second, principally chopping up vitality. This course of causes electromagnetic interference that will get picked up by the radio.
Ford mentioned [PDF] there have been different applied sciences obtainable, corresponding to web streaming, HD radio delivered on FM bands, or some apps that present AM content material, that may make up for the absence of AM radio in its automobiles.
Markey mentioned that 10 automakers — Honda, Hyundai, Jaguar / Land Rover, Kia, Lucid, Mitsubishi, Nissan, Stellantis, Subaru, and Toyota — have mentioned they don’t have any plans to discontinue their use of AM radio. Common Motors and Mercedes-Benz haven’t responded, relying as an alternative on statements from the business group Alliance for Automotive Innovation.
To make certain, none of those automakers went as far as to declare their long-term dedication to AM radio’s survival. Certainly, all indicators level to AM’s waning relevance within the auto business, which Markey argues would make it tougher to convey necessary data to individuals throughout an emergency.

“[T]oo many automakers are ignoring the vital security advantages of AM radio,” Markey mentioned in a press release this week. “Though many automakers instructed that different communication instruments — corresponding to web radio — might exchange broadcast AM radio, in an emergency, drivers won’t have entry to the web and will miss vital security data.”
Based on Markey, AM radio operates at decrease frequencies and longer wavelengths, enabling it to cross via stable objects and journey additional than different radio waves — a function not shared by FM broadcasts. Because of this, FEMA’s Nationwide Public Warning System — via which FEMA delivers vital security alerts to the general public — operates via broadcast AM radio stations.
“AM radio is irreplaceable,” Markey added.
The senator isn’t alone in his considerations about the way forward for AM radio. FCC Commissioner Nathan Simington just lately spoke out on its continued significance to public security and argued in favor of constant to incorporate AM radios in EVs, regardless of claims of electromagnetic interference.
“As electrical automobile adoption will increase, we should not depart behind these in rural areas who rely upon radio for his or her information and alerts,” Simington mentioned, in response to DRG Information.
And final month, a bunch of former FEMA managers urged Transportation Secretary Pete Buttigieg to hunt assurances from the auto business that AM radio will stay an important a part of their expertise choices sooner or later.
However as AM radio continues to vanish from automobiles, one after the opposite, it’s not clear the business is receiving the message.
