I don't think that an accurate reflection of the situation BMW M division is facing.
This year has been a 'blip' based upon the launch of all the M3 variants- I am also pretty sure the vast majority of M series sales are the M3.
I have to say, I don't understand the business logic the m versions of the X6 or X5. Don't think they are going to be big sellers.
M series division are going to have to concentrate on producing smaller engines, with better mpg delivering similar power.
I think a M series version of the 1 series would be a seller....
