M5 M5 diesel? More powered of the M550d

[beckervdo]

On the italian forum BMWPassion.com the forum user MC007 says that BMW would assemblea diesel enginewith threeturbochargers, morepowered of the M550d,to implement nextBMWM5Diesel F10.
The powerwould be greaterthan 480hp with a torqueof 800Nmto be transmittedto the ground,withonlyonerear wheel drive.

How much is real this?
I remember that the internal code of the M550d's engine is FH81.
Anyone know about a TU?

Would love to see it happen as would Goodyear, Michelin, Pirreli, Dunlop, etc, etc.

That would have to be a v8 diesel and that would be too heavy. I dont see any truth in that

More torque than the car could handle? Not useful. If any M car rocks a diesel engine in the near future then it would be the Next X5 and X6.

I just find it comical to think that 800Nm (especially diesel torque which isn't as progressive as with a petrol) driving only the rear wheels would be seriously considered a viable option.

You would the speed of tyre change of an F1 team to not make you feel that all of your time with the car wasn't spent in the shop. lol
