I wasn't talling about production I was just talking about development. The development of all M /// cars takes place in Germany, there is a seperate M// division factory/facility where all the mules and development cars are built. For hot weather testing they will definitely be taken to the US. If there is an M/// version of the X5 it will be built in the US.

Personally I doubt a full M/// version of the X5 will be built, more a model that has been "breathed on" like the E53 4.6is and 4.8is. It's a bit like Audi doesn't have any plans for an RS version of the Q7, though there are bringing out more powerful models like the V12 Q7 TDi which will obviously be very quick. It dilutes the brand/ethos of M/// by producing an X5. An M/// version of the X3 would make more sense as it's a smaller car but I believe that I am right in saying that there's been no discussion of that and that car is obviously a lot further along in the production cycle.
