About 3500 miles into Limited with Ecoboost and am getting 27 - 29 mpg so far, 75% of which is highway. Don't notice any power / performance issues whatsoever. In fact, my 5.4 Expy that I had for 12 years and 225,000 miles had 265 hp, whereas this is 240hp. Heck, my '95 t-bird 4.6l had 200hp. So going from 0-60 in about 7.5 sec and getting close to 30 mpg is very much a no brainer for me, even with the additional front end cost. I also would expect re-sale value to account for some of the add'l up front cost, particularly as fuel prices continue to rise. The Range Rover Evoque basically uses the same motor (made in Spain I believe) in a fairly high-end vehicle, which has been universally well reviewed.
Thankfully, my boat is only about 1500lbs, so can pull it with no issues. Kinda wish Ford would use some of their European diesel's over here. They can make financial sense when getting 40-50 mpg, even with increase vehicle & fuel cost. Performance is much improved with the new turbo diesels (no lag, tons of torque).
