The cheaper cost of premium diesel and improved fuel economy is a "nice" benefit of choosing this engine, but not the driving factor around choosing it.
It may be true for a SUV, but who needs 400+ pds of torque on a normal car?
The price of gas in europe is 2$+ a liter, and 90% of what you see on the streets is the smaller diesel engines. The day we pay the same here the choice will be natural.
