Grotti Turismo XP4

The Grotti Turismo XP4 Does not have any Engine sound. After purchasing the car and driving it, there is no sound with it.

I would like to have a better sound, its an exotic sports car so perhaps a v12 sound or even a super charged v12 would be insane. If it can have some crackle and pops and be very agressive that would be nice to hear. Would also be happy with a very deep v8 sound.
