Automakers moving into an electric future are locked in a battle with broadcasters concerned about the potential loss of an aged and fading technology: AM radio.
Major carmakers, including Tesla Inc. and BMW AG, are omitting AM tuners from electric vehicles, citing electromagnetic interference with the frequencies used by the century-old broadcasting service. AM radio is particularly susceptible to disruption because it uses frequencies like those emitted by EV systems, which can overwhelm the radio signal and make it unintelligible. FM stations operate over different wavelengths. Shielding radio reception gear can be costly and complex, especially when vehicle users can access AM signals via digital platforms. READ MORE
