Additional sound deadening is a feature of the high package on Bronco and available in the Outer Banks, Badlands, Wildtrack, and comes standard on First Edition. Some of you have asked about details of the feature and what it actually is. Ford has confirmed to Bronco Nation that the additional sound deadening material is located in the engine bay and is designed to absorb engine noise.
So there's extra insulation / sound deadening material in form of battery cover , firewall insulation, and a hood liner.
