The House overwhelmingly approved a bill requiring AM radio in new cars, defying automakers. The bill now heads to the Senate for expected passage.

The vote was a rebuke to car manufacturers who had argued that AM radio is obsolete and costly to include in electric vehicles due to electromagnetic interference. Proponents say AM radio is a vital lifeline during emergencies.

The bill's passage in the House sets up a potential showdown with automakers, but with broad bipartisan support, it appears poised to become law.
