In the most recent issue of Consumer Reports, they say too much road noise enters the cabin. I have a 2014 S Grand Touring and haven't really paid a lot of attention to the road noise until I recently drove a 1 year old Ford Fusion. That thing was quiet! I did a little test on my Mazda3. When driving over light gray pavement, there was road noise. When the pavement turned to the dark blacktop, there was almost no noise. I think it's the Dunlop tires. Any input from you all?
