Audio technology helps preserve sound of silence in
electrified luxury coupe
The all-new 2014 Cadillac ELR’s interior is so quiet when
running on battery power that the electrified luxury coupe’s development team
took care to keep it that way when the on-board gas-powered electric generator
turns on for extended-range driving.
ELR uses active noise cancelling to uniquely preserve the
peace and quiet. While most cars that use this type of sound-neutralizing
technology aim simply to mute exhaust boom at low engine speeds, such as when
idling, ELR uses it across all engine speeds.
