Why Is AM Radio Making a Regulatory Comeback in Vehicles?
AM radio, a broadcasting technology over 100 years old, is poised for a comeback in US vehicles as lawmakers push legislation requiring all new cars, trucks, and SUVs to include AM radio at no extra cost. The key reason behind this move is the critical role AM radio plays during emergencies, particularly in rural or remote areas where cellular networks may fail. Unlike FM or digital streams, AM radio signals generally travel farther and remain accessible in crises, providing emergency alerts, weather updates, and local information that can be lifesaving.
This push reflects a broader concern about preserving a reliable, low-tech communication channel that doesn’t depend on cellular networks or internet connections, which could be disrupted during natural disasters or other emergencies. Farmers and older Americans, among others, rely heavily on AM radio for essential information beyond just entertainment, making this legislation a public safety measure as much as a connectivity issue.
How Will This Legislation Affect Electric Vehicle Manufacturers?
Electric vehicles (EVs) are likely to face the biggest adjustments if this AM radio mandate becomes law. Many EV makers, including Tesla, Rivian, BMW, Volvo, and Polestar, have already removed AM radio hardware in some models, citing electric motor interference that degrades the AM signal quality. These manufacturers prefer streaming services and Bluetooth audio as replacements for traditional radio.
However, the proposed law would compel these companies to reinstall or provide AM radio receivers without additional cost, impacting around 2 to 2.5 million vehicles annually. This means EV manufacturers must reconsider their infotainment systems, balance technical challenges with regulatory compliance, and potentially invest in hardware solutions to mitigate electromagnetic interference. Meanwhile, automakers still including FM radios will face fewer changes since many AM functions can complement existing FM services.
What Should EV Buyers and Enthusiasts Expect Going Forward?
Consumers interested in EVs should be aware that regulatory priorities are shifting to ensure critical broadcast capabilities remain accessible regardless of new technologies. While streaming and smart infotainment systems offer convenience and a vast media selection, they depend on cellular and internet infrastructure, which is not fail-safe.
The reinstatement of AM radio could enhance vehicle safety and emergency preparedness, especially for users in rural regions or those who travel off-grid. At the same time, EV manufacturers will need to innovate radio hardware design to reduce motor interference and seamlessly integrate AM reception into modern vehicle systems. Buyers may see modular or improved software-defined radio solutions that blend streaming and traditional broadcasts efficiently.
Ultimately, this reflects a balancing act in EV technology development: embracing cutting-edge digital features while preserving resilient, broadly accessible communication channels that serve public safety needs.
