You’re going to have to test drive many to see if they meet your individual needs.
Sooo many variables reduce or allow road noise. One of the biggest that YOU can change after you own a car is the tires.
The other variables are built in to the car and the higher end cars are usually quieter because they invest in that technology…making it a higher priced car.
Everything from the suspension components to how the body panels are mounted can make a difference . Some brands even invest in body panel coatings and sound absorbing insulation.
Different cars within the same brand will be different too.
My 06 Escdape hybrid is very noisy compared to my 08 Expedition which is amazingly quiet and smooth riding.
