do you have older versions or something in the mods oder vehicles folder? because it looks like you have the mod 2 times
its akward that it works for everyone but not for you. move your beamng files ( which is in AppData\Local\BeamNG.drive\Latest) everything away. then install the mod again and try it it should be something on your file side i guess
In the Version which ist published, no. But in the Next Update they will be added, i'm done with those 2 engines
