Just read this the 2015 Navigator will have CO Boost engine
http://www.lincoln.com/navigator-reveal/With a 3.5L V6 EcoBoost® engine, drivers experience a smoother, more sophisticated sense of control than the previous model. This newly added engine's 370 horsepower, 430 lb.-ft. of torque*, and twin turbocharging, make for an overall more efficient machine. Elegance and command, it's a completely refreshed driving experience with just the right amount of kick and glide.
Wish I could get that engine in an Expedition
The Lincoln is too pricey
