The only good thing I can say at this time about the vm v6 is that the injectors are easier to test than in a crd Cummins.It will take over a day to change the turbo on that v-6.

With this engine available in the 2014 Grand Cherokee's, 1500 1/2 tons and soon via Rams new panel van - I'm sure techs will come up to speed on the engine quickly, plus it has been in successful use in Europe.

Now for that incredible 8-speed tranny (same one in my 2014 SRT Grand Cherokee as well as my friends Bentley, Audi uses it too) - what an awesome piece of engineering.

We always chat about the engine but let's give the tranny a little love too (ok - and all the Chevy/GMC Allison folks jump in on 3,2,1...)

My primary motivator to move from my 2012 QX56 to a 2014 Ram 2500 CC 4x4 w/Cummins is very simple. OVER capacity. I spent a lot of time on both the Ram/Cummins forum and the Ram forum getting smart (er) about the performance of the vehicle. What I came up with was a very strong theme of the durability of this engine and the major positive change in the RAM product. The weak link in their vehicle has been the Alpine Radio and UConnect system. No radio, no truck. And it seems a fair number of folks in the '13 RAM have had more than one radio. VERY few issues with the engine, though the EPA regs and the requirement for DEF are clearly unwelcome by owners. The guess is 9 gallons of DEF for 5,000 miles (or thereabouts). For sure, I am going to enjoy going up (and down) mountains with 800 pounds of torque (vs.440 in the Infinity)....and the standard engine braking system gets rave reviews. Folks are NOT happy about waiting until December to be able to have the new Italian diesel in the 1500, and the curious are checking it out in the new Cherokee.

BAB,

I have used roughly 6.5 gallons of DEF with about 8000 miles on the truck. I believe my DEF tank holds 5 gallons. 1800 miles has been towing our 27FB Serenity. DEF was actually(for me) a welcome addition to the RAM. I had a 2010 2500 and the fuel oil dilution was horrific. I was changing oil every 6500 miles or so, which can really hit the cost of ownership equation. I am now at 8200 miles and I have 50% of my oil life(according to the EVIC) and about 49% on the fuel filter.


I personally have not had any problems with the 8.4an Uconnect system on my RAM. You can even update the software yourself by downloading it from uconnect and saving it to a thumbdrive. It works well with my ipod touch, iphone and music SD card.

I think you will be pretty pleased with the RAM as a tow vehicle. The combination of the Cummins with the exhaust break is absolutely fantastic for high altitude mountain towing. I test drove the GMC Denali 2500 , the Ford King Ranch F250 and 2500 and 3500 versions of the RAM before making the decision.

I am a big believer in having more TV than needed, vs being on the edge of the engineered towing capacity.

Reading how fast one is using the DEF fluid (urea), I wonder how that cost compares to the cost of oil changes.... Just another way to get into everyone's pocket.

Your long-term costs with DEF will be lower, especially if fuel prices rise. The benefit of more aggressive engine tuning is there from Day One, not just better fuel economy.

The Cummins v-6 and v-8s were road tested in Ram pick -ups back in 08.I had a ton of underground photos of both on my phone that sadly crashed .Both Versions were in San Diego for a diesel emission conference at the time.They were both considered light duty as is the vm v-6

These 1500 diesels should be hitting the dealers lots in a week or few.

The Dodge website give MPG numbers of 17 city and 25 Hwy with a tow load of 10,800 for the four wheel drive model.

240 hp and a 420 torque rating. I wonder how that will pull a 25 foot Airstream over the Grapevine or other steep as heck grade.

I'm tempted, but our 2012 Ram 5.7 does a great job (11-13 mpg) towing, I don't have any trouble with the transmission hunting gears, just find the gear I need and leave it there.

I would expect to see a 4 mpg increase in fuel use with the little diesel but with diesel cost ranging 30 to 80 cents more per gallon lately, the true cost of fuel per mile may still make it the most expensive to operate.

What I really want is the 8-speed transmission, always the precise gear choice for the task.

Remember torque gets the job done but it is the horsepower that determines the time work is performed in.
The early diesels would get to the top of the passes with their 400lbft of torque at 45 mph give or take depending on weight

The early Cummins were also EGT limited in the mountain climbs, so the 45mph was also an attempt to not melt the turbo charger or overheat the autotrnsmission, if installed.

The turbocharger designs have improved along with pre-colling the air to help keep EGT temps reasonable. At 1350 degrees, one is close to a failure if the temp stays there very long.

I monitor EGT, inches of boost, fuel rail pressure, transmission oil temperature and rear differential oil temperature on an Insight Edge digital gage to be sure things are running at a reasonable numbers when under a heavy load.

How are you measuring INCHES of boost ?

Factory sensors provides the boost and fuel rail pressure data to the Edge Insight. We added a temp probe into the exhaust manifold, transmission housing and both differentail covers.

If you're asking about the inches part (since that's what you put in all-caps) "inches of mercury" is a common unit of measure of pressure for medium-pressure systems (low-pressure systems like our propane system in Airstreams use inches of water.)

1 atmosphere = 14.696 psi = 29.92 inches of mercury = 100 kilopascals
