Because they cant afford to make it.
Fact: Those pics have been doing the rounds for what 2 years now? So even if they released the Car next week, it's already 2 years behind the latest generation Of EVO's etc, Ford won the World Rally Championship last year, and did fuk all about it, take the autosport show for instance, there was no official ford stand FFS, and that was down to them being in financial difficulties... I got that straight from a Guy at MSport.
Goodwood a weeks or so ago... they had the crapest of all the manufaturers dispalys and had fuk all performance cars there...
Every way you look at it, ford just don't care about that market anymore, they need to spend there money on cars that will recoupe the money, ie: mass produced dross.
