I believe its a prototype 4x4 Cosworth Escort, I may of got the pic from on here ages ago I can't really remember but it was one of a few development cars they built.

I said one of the first but I guess the RS200 came before that but I believe it was the first front engined 4x4 they built, shame there isn't more info on it as it was probably a impressive car and with only subtle body mods a bit of a sleeper !
