Packaging different classes or fbx

Hi all

I am having a game size of 2gb and my question is I am having four cars and all cars are not used at a time. So, I wanted to pack each car class as one package (4 cars = 4 packages and one main game APK without 4 packages)

Now I will install the main APK file and in that main APK file, I will keep the path where all the 4 cars are at. I wanted to load each car whatever I need at the same level only

Is there any solution for this in unreal engine please help me I am not that much well versed in this concept or in Coding
