Apart from all the crap versions i welcome a WRC model. It wont be a diesel though, so if they do do a 200bhp diesel model it wont be the WRC version, that will be a 1.6 turbo petrol with a bit more than 200bhp.
WRC cars are 1.6 petrol turbo in the new FIA regulations.
Although i'm just presuming, BMW may do something stupid and promote diesel....But it would fly in the face of the direction of international motorsport, which is becoming diesel free thankfully.
