For some manufacturers, an extra quiet interior is part of their design focus. The extra insulation or dual pane side windows add cost, compexity, build time and weight. Lexus used to advertise that their motors ran so smooth you could balance a coin on it while running. If you need a car that can balance a coin while runing then perhaps an earlier Lexus LS 400 might be your choice
Trade off is that they will cost more, have worse aerodynamics, handle worse, get worse fuel economy etc.
Tesla cars tend to be pretty quiet due to smooth electric drive, They seem to get even quieter after a few years of production as build quality improves and lots of little adjustments all add up to the cars evolving better and better. Wind noise is not determined by the type of engine, so Tesla will have no edge there.
Some cars can be made quieter by using aerodynamics to bend the wind away from the offending areas. This will make the car quieter, but less aerodynamic.
Stand next to an idling Tesla or ICE and the ICE will sound like a bucket of bolts in comparison. Some of the ICE comparisons also come with smaller and narrower tires and wheels. By running skinny tires the cars can be made quieter as well. (but worse handling).
Tesla has announced that they could make their cars much quieter if allowed to replace side mirrors with cameras. Lots of wind noise is caused by those mirrors sticking out of the smooth body. In addition to less wind noise, it would also allow the vehicle to get better range as that significant aerodynamic drag would be eliminated.
Photos have shown that the mirrors on the new Y stick out much less than those in the Model 3/S/X. This alone might be causing some of the reduction in wind noises.
