Superior NVH for a Quiet Cabin

All these features can be enjoyed to the fullest, because CX9's cabin is designed to be quiet and relaxing, even at cruising speed on the motorway. Its new V6 engine and automatic transmission are smooth and quiet (see Powertrain below). And it supplements this with noise-suppressing foam applied at 22 locations in the body shell - the most of any Mazda vehicle ever - and various structural technologies which effectively dampen road and wind noise from reaching the cabin.
