No, only MRT, BF1, Scirocco and FBM are based on in real life cars and they are fully licenced ones.
Others are a fictional cars but with some kind of similarity to a real life cars for example: XRT kinda looks like mistubishi starion but its not a licenced ingame car.
You can find some similarity in other cars like XFG is looking like seat ibiza in front but mixed with citroen AX rear.
edit: It's also very similar situation to GTA games series where you have to drive a car named patriot but you know its a hummer.
