With Sync you can call the tune, but Ford still needs to face the music
At 55 mph and below, the Focus is quiet inside with very little wind noise and some tire noise. At 60-70 mph, wind noise is louder and mostly from the side mirrors. Much faster than that, and wind noise increases a lot, generated by the un-shrouded windshield wipers and the mirrors. In short, at the speeds that most people drive, the noise won’t rise to objectionable levels.
