If it was turbo related it would probably occur around the same level of rpms regardless of vehicle speed (mph). Does it occur in every gear or only above 50 mph? It could be something as simple as the weather stripping around your doors. Sometimes this needs replacing when the car gets a little older to prevent "whistling" sounds when on the highway.

Could also be driveshaft wear. That normally makes a whining sound. Worth taking it back to the dealer and getting someone to come out and check it out.
