Thanks for the post, interesting to follow the developments here.

I wonder about a few things:

How can the trailer capacity be 5000 lbs 'unbraked'? Doesn't fit to me, since the difference between braked and unbraked is a chassis limitation, not an engine limitation, if I understand the engineer's concerns correctly. Also, a diesel has less compression braking than a gasoline engine, so the weight limit would be lower, not higher, with respect to braking. Certainly the torque numbers support a big tow rating, but that engine doesn't likely slow down a trailer very well.

How will BMW meet the 2008 pollution regulations? Will they use urea injection or a variation thereof? Will the engine be similar then to the current Euro rating, or is it a different animal altogether?
