ford should install those 4.4 l turbodiesel engines,it's building in Mexico and sell them on most expensive SUV, the Range Rover in Europe
it's over 300  HP and is efficient better than any gasoline engine
Ford should install them on Navigator,Expedition,F 150 and Raptor
i would buy a Raptor with that engine
u don't need more power, because u don't fly with that vehicle
take example from BMW M 6, 3 littre turbodiesel 380 hp, 60 mph in 3.8 sec

If you are looking at 4.4 liters develop the Mazda SkyActive 2.2 liter inline 4 into a 4.4 liter V-8 instead. The four delivers 173 horsepower and 310 ft-lbs of torque. Imagine that in a V-8. Plus it uses no D.E.F. (diesel exhaust fluid).
