Lots of Engine Noise from 2019 Pathfinder?

Hey all, we recently purchased a 2019 Pathfinder with AWD and tow package. So far I really love the car. The only thing that has me slightly concerned is the amount of engine noise. Previous car was a 3.5L Toyota Sienna, so same engine size and orientation, but the pathfinder has a lot more noise and vibration. Low rumbling vibration at 1000 RPM, higher pitched whirs while coasting. If this is normal and everything is working fine, I'm fine with it. Just wondering if it might be a sign that the transmission is working too hard. No warning lights are on in the dash and seem to be getting about 320 miles per tank city driving.
