Its a Motor Trend comparison, but still pretty decent.

 

Powerstroke = Celeron (sounds good to the average Joe)

Cummins = Pentium (quality)

 

The review was pretty good. I agree with the auto transmission comments and the ride quality. The Ford gets better mileage loaded than it does unloaded? ????? Really? For the Ford to have more power it does not perform all that much better. The rear leg room is better in the RAM and the Cummins is proven....... plus you save $8,000 + with the RAM. NO BRAINER THERE

 

Good God some body beat that Ford with an ugly stick....


That grill


If its that close, Ill take the tried and true.

 

Yea I'd go fo the engine that has the head start on things. 6.7 has been compliant for emissions since 07.

 

they want a real comparrision let me have each for a week then you can get real info

 

It was interesting that when ford tested the 2 trucks (in another test), their truck got 4 to 6 mpg better fuel economy than the dodge. Yet when MT tested it, it was only 2/10ths better. The review of the tranny was interesting as well. Said the ford was smoother shifting. If I'm towing heavy, I do not want a tranny sliding between shifts so its smooth, to me, sliding equals heat. Give me a good firm shift. For 10 grand cheaper, give me the dodge as well...

 

Have a look at this thread in the 4th gen section:

I agree, I'd take the Cummins over the Ford anyday. But I am curious how fords in house 6.7L will do in the long run. I've done alot of reading on its development and it actualy looks like a very strong motor. They seem to have fixed the issues that plauged the navistar motors before it. It also has one of the strangest turbo's I've ever seen!

On a side note, according to GM the 2011 Duramax will be pushing 397hp and 765tq, and run 680 miles highway on a 36 gallon tank! Just imagine the possabilities with aftermarket mods........

 

Doesn't mention how much urea it uses, or what it costs...

 

Urea averages $6.50-7 a gallon. I believe it holds 7 gallons and supposed to run up to 7500 miles on it. So your looking at an added $49 every oil change to fill up the urea tank. BUT we all know most diesel entheusiasts are going to get a tuner that will delete the urea and DPF.

 

I have a problem with the HP wars now. Most of us up the power to this level because we are going to use it or at least have a handle on it. I can't imagine the trouble a soccer mom can get into with a jacked 4X4 on wet pavement with 400 hp...

Oh and the mileage thing is a real problem too. Unless they have re-invented the combustion process, it still is going to take 150 hp to push that large vehicle down the highway. So unless they are getting free heat energy from that 5th radiator, I don't know how you can do it that much better.

 

Well there are a few ways they can increase the mpg and efficiency of the newer diesels. One is the higher injection pressures and piezo injectors, they do a better job of atomizing the fuel for a more complete burn. Second is the fact that compression ratios keep dropping. This means they can run more base timing than the older higher compression engines, while still maintaining simular cylinder pressures. That also increases HP and efficiency of the combustion process. There are other improvements they have made, but those two are the major things that will increase mpg and power at the same time.

Well,

At least it will sound ok as long as you can keep it running.
