I remember my mazda 3 being awfully noisy. There was a lot of wind noise and the road noise was really awful. I had to sound deaden all the doors, hatch lid, trunk floor and around the wheel wells. It didn't make much of a difference. So I've heard that the new cx-3 was designed with weight savings in mind so the engineers were able to squeeze in some more sound deadening materials. Apart from that, there just isn't any proof of this being the case. Has anyone removed their door panels recently or any other panels that may have sound deadening materials underneath? Underneath the door panels should be a fibrous door material like this found in my hyundai sonata. Thanks!
