Diesel Exhaust Fluid................had me laughing.

 

it's basically urea injection, common in Europe..

 

When is there enough HP & Torque? I think most owners want better mileage.
I am sure that Cummins will answer the call, as they always do, come 2012.
At what price does all this HP, torque, towing capacity come? How long will thse engines last? Only the Shadow knows!
I met an RVer witha 2009 6.7. He was most unhappy with the 6.7 compared to his 2006/5.9. He recently put in a Smarty and gutted all the pollution stuff. Much better performance and at least 2-3 mpg improvement. He had been getting 10-12 arounf town. In Texas, there are no emission tests for diesels.

 

So you want Dodge to start using urea injection? Cummins is ahead as their engine already met the stringent emissions tests without the use of urea. Ford and Chevy both have to use it to even sell their product. Personally, I think in a long time Dodge is finally ahead of the curve with looks, comfort, engine and tranny.

Now, with that said, I do think all of them are sandbagging on mileage. I think the mileage could be a lot better from stock trucks and it looks like Ford let the cat out of the bag on this one. There have been reports of the 6.7 Scorpion getting very nice mileage all the while having big HP and TQ.

 

The horse power race has been going on for decades. That's what the muscle car thing was all about in the 60s and 70s. What's happening now with diesel trucks is exactly the same. We are at the same stage today that the cars were back in the early 70s. Emissions is coming ahead of fuel economy. To me at the end of the day, it is towing and reliability that counts. The truck I now have is by far and away the best tow vehicle I have ever owned. With a load in the box and my 30' travel trailer hung on the back, the trip is seamless and always enjoyable. From what I have seen in my travels, the 6.7 Cummins Dodge will out tow its competition. I have no doubts that that will continue to be the case in the future. Personally I do not want anything to do with urea.

 

The current 4500/5500 chassis cabs use urea already, as do the 6.7's for RV aplications. I think I read where urea will be on the 2012 2500/3500 trucks. pcm

 

Interesting. I wonder if they will get to bump the HP and bring back a little mileage then too. Might have to wait to buy a new one when they unveil what it is they're going to do. That F-450 with the 6.7 sure is a good looking truck though.

 

Yep...I want Cummins to tune my engine to make efficient power, with LESS EGR and LESS DPF...then I'll spray something extra into the exhaust to make the engine clean. Not too mention, even after I pay for that stuff, I'll still save money on fuel!

Yes, I would love that!

Allpar.com speculates that "The Cummins straight-six diesel is still planned for future Rams and may get a kick up to 750 lb-ft of torque or more when coupled to the upcoming eight-speed automatic in 2012. The new 8 speed has a rated capacity of 800 lb-fts." pcm

 

8 speed auto...very interesting. Surprised that the 6-speed was so short-lived.

 

Alot of us have been hitting on Dodge since the 4500/5500 came out to build a non commercial version of the truck that is not limited to 26,000lbs GCWR.

Your statement atop "6.7's for RV Application" sounds like you've read something that indicates a change in CGWR. I visit ALPAR at least once a month, and have seen nothing for CGWR. Maybe I missed somthing. Please advise.

As you might know, the new 3500 can tow more than the 4500 just on curb weight differance as specified by Dodge.

 

I got the info regarding the 6.7 for RV application from the Cummins web site and several of the class a RV manufacturers websites. pcm

 

Please share the links.

Thanks
