4.4i twin turbo torque vectoring X5?
 

You can't help but like the thought of 22 mpg in a 400 hp twin turbo X5. So, any insight as to if, when, we can see that engine? And how about the torque vectoring differential? The X6 package is great for anyone without kids, pets, and a job that has you needing a 3rd row on occassion.
