Merc C9 has a very quiet engine note and is being drowned out by environmental noise. My audio levels for all cars is to set the engine to 100% and environment to 60%. At these settings the C9 engine is still drowned out and you can’t hear it.
The sound is noticeably thinner in this game for all cars, but this one in particular is very poor.
I’m using primarliy bonnet cam.
