Driven both the sedan and hatch. Yes, the hatch has more road noise that the sedan. under the spare tire is only thin sheet metal... a little "dynamat" (I used second skin Damplifier Pro, and luxury liner) will reduce quite a bit of the road noise. I personally ugraded my tires, which also made quite a difference (Bridgstone Serenity Plus Turzana). Asphalt is much quieter than concrete interstate where I live.
