One of the issues that concerns me with the 3.0D, and its transmission, is the relatively high torque that they get from the common rail diesel engines. When the X5 fist came out the 3.0D pushed out 410NM, whilst later versions went up to 480 and then 500NM. This is the same torque as the 4.8iS... sure the surge is all over a lot quicker than in the V8, but basically the initial stress on the transmission must be almost the same. My question is this; is the transmission in the 3.0D designed to be as strong as in the 4.8iS, or have we got a lesser transmission and are we therefore destined to suffer a higher level of failure?
