They literally all have the same engine. S58. They should sound a little different, but not this different. G82 M4 and G80 M3 sound nearly identical while the G87 sounds a lil more tame. At the very least they should all sound similar to the G82 M4 in game. Currently the G80 M3 and G87 M2 sound like they have the previous generation engine sound ( S55 ). This is wrong and needs to be corrected.
