But the V12 from the 760il is very usable in an X5 and would make the X haul ass. Its got tons of torque everywhere.

What i heard is that the new 2007 X5 will be available in 3.0i and 3.0D, 4.8i from the curent 4.8 will replace the 4.4 as the base V8. and for the IS replacement they may go to an alpina 5.0 v8 motor or use the V12 from the 760 and call it a 6.0is. either the v8 or v12 will be putting out around 450hp And they will all only be offered in auto trans as usual.
