Beijing, December 12 (Xinhua) according to the New York Times, AM radios may be left behind in a future full of electric cars. Carmakers say electromagnetic interference can cause static electricity and noise in AM transmissions, annoying customers. Broadcasters say they may lose contact with their core listeners, who rely on radio to respond to emergencies.

For nearly a century, drivers have been listening to AM radio, which includes news, traffic, weather, sports and various other programs. But as electric cars begin to capture more of the U. S. market, the main products on the dashboard may disappear like manual crank windows and car ashtrays.

More and more electric cars are abandoning AM radios, which broadcasters say is a worrying shift that could cause trouble for radio stations and deprive drivers of a key source of news in an emergency. Carmakers say electric cars produce more electromagnetic interference than gasoline-powered cars, which interfere with the reception of AM signals and cause static, noise and high-frequency buzzing (FM signals are more resistant to such interference).

"to prevent customers from being frustrated by poor reception and loud noise, we have decided not to install this device on vehicles equipped with eDrive technology," BMW said in a statement. EDrive technology is a system that provides power for its electric vehicles.

Tesla (Tesla), Audi (Audi), Porsche (Porsche) and Volvo (Volvo) have also removed AM radios from electric cars, and Volkswagen has also removed AM radios from its ID.4 electric suv, according to automakers and the National Broadcasting Association (National Association of broadcasting). Ford said it would also stop carrying AM radios in its popular 2023 Fmur150 Lightning electric pickup truck.

Some experts say the problem of signal reception is not insurmountable. Xperi Inc., an entertainment technology company that owns HD Radio technology. Pooja Nair, a communications systems engineer, says EMI can be controlled by shielding cables, filters and carefully placing electronic components in the car.

But such a change will require money and effort, and it is unclear whether automakers are willing to invest more in the services of AM radio enthusiasts.
