Image Credit: BMW.AM radio has been part of the in-car experience for nearly a century, but its future in new vehicles is suddenly a political fight. Automakers have been moving away from the old broadcast band, especially in electric vehicles, while lawmakers are pushing to make it mandatory.The latest effort is the AM Radio for Every Vehicle Act, which has been folded into transportation legislation. If passed, it would require automakers to include AM receivers in new vehicles, regardless of whether companies believe customers still want them.Supporters argue that AM radio remains an essential emergency communication tool, especially in rural areas and during natural disasters. Automakers counter that the mandate would add cost, create technical problems in EVs, and preserve technology that many drivers rarely use.AdvertisementAdvertisementThe debate has turned into a clash between public safety, industry cost, and the changing way people receive information. It also raises a bigger question for modern cars: should old technology stay onboard if it still works when newer systems fail?Why Automakers Want To Drop AMImage Credit: Toyota.The main issue for automakers is interference, particularly in electric vehicles. High-voltage motors, inverters, and related components can create electrical noise that disrupts AM reception, making the band harder to use cleanly in EVs.Industry groups argue that solving the problem is expensive and technically imperfect. The Alliance for Automotive Innovation has previously estimated that a federal AM mandate could cost the auto industry billions of dollars by 2030.Automakers also point out that emergency alerts are no longer limited to AM radio. FM broadcasts, satellite radio, internet services, cell networks, and digital warning systems now play major roles in public alerts.Why Lawmakers Want AM ProtectedSupporters of the mandate say AM radio still matters because of its long range and reliability. AM signals can travel farther than FM, especially at night, making them useful in rural regions where cell service or broadband access may be limited.AdvertisementAdvertisementThe public safety argument became central to the bill. Lawmakers backing the proposal say drivers should have access to emergency information even when cellular networks are overloaded, power is out, or internet-based services are unavailable.That argument has attracted bipartisan support. The measure has gained traction because it has been connected to a broader infrastructure package, giving it a stronger chance than previous standalone efforts.A Bigger Fight Over The DashboardImage Credit: Nissan News.This is not only about one radio band. It is also about who gets to decide what belongs in a modern vehicle: automakers, regulators, broadcasters, or consumers.For car companies, dashboard space and electronic architecture are becoming more complex. Every required feature adds engineering, testing, and cost, especially as vehicles become increasingly digital and software-defined.AdvertisementAdvertisementFor broadcasters, losing AM from new cars would be a major blow. Vehicles remain one of the most important places where people listen to radio, and removal from dashboards could accelerate AM's long decline.What Happens NextThe AM mandate still has to survive the legislative process. Its best chance appears to be staying attached to the transportation bill, which lawmakers want to move forward before the current highway and transit funding authority expires.Even if the measure passes, automakers may continue pushing for flexibility, especially for EVs. They could argue for digital alternatives, exemptions, or technical standards that reduce cost while still preserving emergency alert access.For now, AM radio's future in new cars is in Washington's hands. Automakers may see it as outdated hardware, but lawmakers are treating it as a backup system that could matter most when everything else stops working.AdvertisementAdvertisementIf you want more stories like this, follow Guessing Headlights on Yahoo so you don't miss what's coming next.
