The sound is generally fine on this car, good job!
The cockpit sound, however, sounds small, thin, and hollow. Please update the cockpit sound dynamic range to make it sound more like you’re “there” in the car and not the car a few metres away from you in a tunnel or empty stadium.
So, give the cockpit sound some depth, dynamic range, midrange, bass, and loudness and it would be perfect - to relay to the driver the power of the exhaust and motor.
External view sounds could also be louder, thanks.
