DETROIT – 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.

“Acoustic refinement is an important attribute of every Cadillac interior, and ELR is no exception,” said Chris Thomason, ELR vehicle chief engineer. “Considering how quiet the car is during pure-electric driving we knew the generator sound had to be as pleasant as possible, and we were able to achieve it with active noise cancelling.”
