Not sure if this was mentioned but I am disappointed at the lack of intake sound from the cars when using the 3rd person camera in reverse view.
Cars that have very noticeable intake sounds IRL such as the Alfa Romeo 155, Carrera GT, F430 all lack it unless you are driving on the interior cam and even then it's still fairly weak, especially on the 155 in particular as that car sounds much more aggressive IRL.
PD Have done this since GTSport, cars that should have an audible intake sound either do not or it's very weak.
How it should sound:
How it actually sounds ingame:
The intake sound is non-existant with this car when it should be very loud and isn't audible on interior view unless you're in the lower range RPMs.
Older gen games like Forza Motorsport 4 for example has the Carrera GT along with the audible intake sound correctly represented.
It's a shame because in my opinion the sounds of a vast majority of the cars are correct but they are lacking character if that makes sense, the same issue I mentioned about DBR9 on GT Sport vs PGR4, one sounds very aggressive like it does IRL while the other sounds like a roadcar trying to emulate a racecar which brings me to my next issue, alot of the racecars sound far too muted/tame compared to their reallife counterparts; i'd show examples but there are far too many to point out. I was hoping this issue would be fixed with GT7Y but sadly it hasn't yet, hopefully they fix it via updates soon.
