The 4BT get around 25 to 30-mpg on the highway. Bone stock it only hits about 130 to 150-hp but lightly mod the engines can put-out over 500-HP. If you have the money, I've seen some that top out over 700. Besides, you comparing apples and oranges. The key with the 4BT is the torque. There's a YouTube clip where the truck is anchored, in gear, and the engine is idling; the truck is spinning the the rear tires. Even the 6.4L Hemi can't do that.The 2010 Ram is available with 390hp. :rck:
The only way the manufactures are going to make money on the half-ton oil burners is if the fuel mileage is there. If the fuel mileage is markedly better then there will be a flood of plumbers, electricians, and other businesses that would flock to the diesel powered truck. The money is not going to come from Joe Public buying these trucks; it'll come from the business and fleet sales.With the new Ferd Eco-Boast making headlines - not to mention the very low upcharge for that option (plus the diesel like performance), I doubt that anybody could make money with a diesel in a half ton these days.
