So I followed this tutorial: 
on how to add additional police cars and for the most part it worked, I was able to add a dodge charger to police5 slot, which I created and ELS worked. Unfortunately, the car has no sound, the sirens work but the engine is mute. Does this have something to do with the default  carvariations.meta I used which was provided? Thank You
 
 
Edit: So I feel really stupid asking a question I just answered. I went back into the vehicle.meta to search around and see if I messed up. Technically, I did everything correct however I did overlook one aspect. Creating a new unit called police5 was fine, but I was also calling the game to load <audioNameHash> </> for police5, of course none existed thus the car's engine was mute. I resolved this issue by replacing it with audioNameHash>police2</audioNameHash> so I was able to duplicate police2 engine sound and now everything works fine. So sorry about this pointless topic now.
