Technical Reference on correct description of X5M 50d
 

Have noticed that X5M 50d is being reference as X5 M50d. Was given a BMW printout of the reference and the model is designated as X5M 50d on the paper work.

On the instrument cluster it also shows a space between the M & 50d

The X5 M(V8) is referred as X5M, but on paperwork its actually X5 M and badged X5 M

You can buy a M-Sport X5 but they are not badged as a M

So what is the correct reference for this new range of M diesel X5's

Is it X5M 50d or X5 M50d because it looks better when written, but the M 50d is badge this way and not as M50d

I see X5 M50d on the official press release.
