Hi devs, this game is very realistic but there a lot of work to do on the audio aspect of the game.This could be something to be worked for the next update. Sounds for different types of engine, starting sound, sound for the tyres for the type of ground that the car roll on, sounds for parts being destroy (transmition gears, engine component, scraping sound, starting failure), back fire sound, explosion sound and vehicle electronic and mechanic feature (lights on off, flashers, shifting, e-brake, pressing pedal sound), and more Dr1ftxK1ng thanks to have get your attention on this post
Though many people have asked for this since the beginning, this is something the game really needs. The audio is really downgrading the realism. I really hope something is being done, or is planned, to improve the audio.
They are probably planning to add different sounds for different cars, since they added a sound for the covet it would be a shame that others wouldn't have. And the game is not fully released yet, so surprises can/will happen
