There's always a bigger turbo out there, somewhere.

And before you know it, there'll be an in-line six diesel with six turbos in the coming F30 ///Md!!!

I read somewhere, due to geometry of the layout, only LHD available for this monstrous M550D.

RHD without de XDrive for UK market...hehe
LHD onli is for XDrive..so monstrous power to 2wheeler belakang for RHD = wheelspin

Added with sos kicap
Rear-wheel-drive M550d saloon and M550d Touring models engineered specifically for right-hand drive markets are tipped to go on sale in October. The rear-drive pair will come to the UK in place of the four-wheel-drive M550d xDrive saloon and Touring variants that will be offered elsewhere in left-hand drive only.

Maybe a 4th turbo could balance up the geometry for RHD xDrive :4:
