I can tell you this...on a vid I saw of a Obey Tailgater being customized, you could hear the direct injectors working in the engine. Very realistic. After a couple of minutes of the car sitting, you heard the fan kick on.
Can cars get dirty?Atleast like GTA IV?
What about engine sounds?in livestreams they are almost unhearable...its that just because audio settings?
IF you add turbo does it make blow off sounds?(like sultan rs in gta iv)
Are we able to drift at all?
He added a turbo, and you could hear the turbo spool and the blow off valve.
And earlier in the topic, he did say you can drift in the game.
Oh, and there are car washes in the game.
