EcoBoost or EcoBust

We will soon have a diesel 1/2 ton to compare when the Dodge 1500 launches with the Fiat diesel. It will more than likely have the same horsepower numbers as the 3.0 audi and BMW 6 cylinder diesels. (225-250hp and 420lb ft of torque). My guess is that people will see a combined mileage of around 20 compaired to 18 with the eco. Much slower 0-60 times, but probably a tad bit flatter torque curve. It will have DPF, EGR, Urea injection, high pressure piezo injectors, complex turbo. Would hate to be the first year buyer of this truck.

Not sure I agree with your assumptions. The ecoboost makes as much torque as the old 7.3, way more horsepower, and equal to better mileage. Assume that you do the same direct injection and boost, to say, a 5.0 and I bet the torque numbers get pretty close. I do agree that diesel fuel does have more BTU's than gasoline, which gives it an advantage, but the cost and complexity of the emission systems have really hampered diesel efficiency and reliability. My PS 6.4 got 11mpg unloaded and 9mpg towing and choked itself on EGR. Had to spend $1500 bucks and void my warrany just to make it get 14mpg.
The modern turbo-diesel engine can't be matched on both power and mileage by a gas motor. Squeeze-bang with diesel fuel is a more efficient ignition than spark-igniting gasoline, and that alone can't be overcome enough to match power and mileage with diesel fuel.
Because diesel's can take advantage of larger displacement without sacrificing mileage and emissions like gas motors do, the gap will just become larger and larger.
The Euro's have understood this for a long time(maybe thanks to Rudy Diesel being one of 'em), but the American market has been scared of diesels because they can't get the '70s versions out of their minds.
In any event, I'm not saying anything new.. it's all fact, and the world's auto manufacturers are starting to introduce and increase diesel production because of it. They've got ever-increasing CAFE standards to meet, and a customer demand for certain power levels. Diesels are the best way to achieve everything they need right now.

I've owned diesels all my life. Had a 6.7 power stroke before the Eco and a heavily modified cummins. My Eco has all the mods on it (tune, down pipe, exhaust, intake). If you are expecting diesel like performance then you will be heavily disappointed with the Eco. Get a diesel if you want that feel and performance. I wish I had gotten a deleted, tuned, and studded 6.4 over this Eco. Would have paid the same price as I did for my Eco. Hell, I could have gotten a king ranch crew cab 6.4 for what I paid for my Eco AND been happier. Oh well.

I just traded in my 09 Powerstroke for my 2013 F 150 Platinum with Eco Boost for the very reasons Timschnell identified already. The govt mandated emissions have sapped the mileage advantage out of the newer diesel trucks. Sure,the truck might last longer since it is built heavier, and I will surely miss that turbo song and ability to tow anything I could hitch to it. I will not miss the $100.00 oil changes every 5000 miles and the $300.00 oil change with fuel filters every 15000 miles not to mention averaging $.35 - $.80 MORE per gallon of fuel at the pump. I could no longer justify these costs for a daily driver and occasional tailer puller. I think the Eco Boost will serve well as a commuter and should handle the occasional trailer tow for the weekend camping trip. All the while doing so in comfort and high style.
If I were towing heavy and often, then the diesel would be a no brainer. I just didn't need a Clydesdale when a Quarter Horse would do. Oh yeah, and I lowered my monthly payment too.

I went from a 04 cummins 5.9 tuned. For $1500 I gained 150hp/280+tq. Yah it was great but for back and forth to work and in the mud and snow it was horrid. The Eco is so nice to drive every day, light and fast. Yah it doesn't rumble like the diesel but the neighbours are probably happier. Towing with a turbo is great though.
