OEM's sometimes love these early adopters. Let the paying consumer finish the beta testing. Hopefully the overheating issue reported above was an anomoly, or has been otherwise dealt with. If that is systemic of this engine and truck, this will be a short lived experiment for them.
Early production failures can wreak havoc with sales for years. Ask Nissan about early Dana 44 failures in the Titan......

The current issue of Diesel Power magazine has a writeup comparing two equivalently equipped 2014 Ram diesel powered trucks. The 1500 has the new v6 Italian engine while the 2500 continues with the Cummins straight 6.

As has been mentioned time and time again, the ton truck's achilles heel is payload which was 1,140 pounds versus the 2500's payload of 2,180 pounds.

What was interesting is that on the towing test, there was not enough power in the Ram 1500 to maintain speed going up a 7% grade to 5,000 feet with a 7.020 pound trailer behind and the engine temperature red lined at 244 degrees. That test trailer weight is less than the GVW of any current 25' or longer Airstream and less than the empty weight of both 31' Classic models.

So on the flat terrain, the mileage was really great, just don't get into steep hills and try to maintain speed....
So, I just read that DieselPowerMag article.

I think it's useful to note a couple of things... the truck they were testing had the 3.55:1 rear diff, which is not the one I'd choose for a tow vehicle. It was a little over 300 lb over its rated trailer weight, but the truck with a 3.92:1 diff is rated for 1800 lb more than the 3.55. They didn't show the trailer they used in testing, but it's reasonable to assume it's a square-profile camper or utility trailer. The truck maintained 53 mph floored up a 7% grade on a climb to 5000 feet, but they didn't specify the starting altitude so one can't tell how long the climb was.

I don't think it's fair to infer that the engine actually overheated, either. Here is what I see as the relevant paragraph:

Quote:
We saddled up the EcoDiesel first and loaded it up to 105 percent of its gross combined vehicle weight (GCVW) rating of 12,800 pounds. The Ram 1500 had no issues accelerating from a stop, getting up to speed, or slowing back down. Helping to reign in the load in tow is a factory-integrated trailer brake controller. While not overpowered, the truck never felt underpowered, either. The only place where the trucks showed any sign of weakness was climbing the nearly 7 percent final grade on the push to 5,000 feet of elevation. With the accelerator stapled to the floor, the truck’s speed dropped off to 53 mph, and engine temperature climbed to an almost alarming 244 degrees. Thankfully, as we crested the summit, the engine temperature returned to normal and we never experienced any other engine temperature issues during the remainder of the test. Overall, we were extremely impressed with the truck’s towing abilities. After a 260-mile round trip, the EcoDiesel averaged an astonishing 19.46 mpg, fully loaded.
I do not know what the "official" overheating level is defined to be, but the writer never uses the terms "redline" or "overheat" and the diesel supplement manual for the RAM 1500 states that there is an engine temperature warning light that behaves as follows:
Quote:
This light warns of an overheated engine condition. As temperatures rise and the gauge approaches H, this indicator will illuminate and a single chime will sound after reaching a set threshold. Further overheating will cause the temperature gauge to pass H, a continuous chime will occur until the engine is allowed to cool.
No such behavior was described in the article, though it may have been imminent. How serious the temperature issue was is hard to infer since I don't know what the critical temperature is, nor does the article say much about the conditions where they conducted the test. It may have been even less of an issue if they'd used a truck set up to tow as much weight as they were towing.

PS: on edit, I see that I forgot to write part of what I'd intended. I do agree that the RAM 1500 is a bit light on payload compared to what you can get on an F150 or Silverado/Sierra 1500, which is too bad because the engine seems appealing, to say nothing of the fuel mileage it apparently delivers.

Test drive

I test drove a new RAM 1500 EcoDIESEL last week. Two test drives actually. I must say I am very impressed with the quietness of the ride and amount of TQ it presents when you "staple the pedal to the floor"! I took a couple of videos to share the awesome sound of the Italian diesel engine.

Coupled with the great German transmission, I think this is going to be a very efficient and capable tow vehicle in the correct configuration. (3.92 rear end)
The dealership has agreed to let me test tow my Ambassador when they have one in stock with a trailer brake controller. I'll let you know how that goes when the time comes.

So, I'll be picking up my EcoDiesel this Thursday and be heading out from Montreal to Salisbury, MA for my first rally of the year (very hilly in parts of I89 in VT & NH).
I'll have my '10 30' FC in tow, so I'll give everyone a full report early next week.

OK, so here's my report:
Remember, I'm coming from a '12 RAM, 1500 5.7 3.92.
My new RAM ED with the 3.55 is simply amazing; better than I hoped for.
It cruises very relaxed at 65mph even through the mountains. One great improvement which probably has nothing to do with the diesel is the cruise control. It reacts within 1 mph to adjust throttle to keep the selected speed even through the mountains.
There is no doubt the ED pulls easier than the hemi.
I can't implore enough to anyone thinking about buying any RAM 1500 to get the air suspension. Wow! Wow! Not sure you heard me; Wow!!
The truck keeps it's height exactly as when carrying no load. This allows for full suspension travel even when hitched. Great ride!!
I'll have to get a new draw bar for my hensley as the trailer is now a little nose high due to the air suspension keeping the ram level.
Mileage while towing is 15mpg. Average mpg while not towing is 23mpg; my average with the hemi was 14.
Great truck!!!!

Test Tow

Tomorrow morning the dealer is bringing a new RAM 1500 Ecodiesel Crew Cab 4x2 to my shop so I can take my '72 Ambassador out for a test tow. I'll post a report on Sunday.
I have been reading the towing threads on the RAM1500diesel forum. I sounds like 15 MPG while towing is very easy. Even more with a lighter foot.

Test tow

I got the chance to test tow my 1972 Ambassador with a RAM 1500 Ecodiesel today. It was a superb experience! I didn't want to stop.

It isn't the exact configuration that I want, but it is the engine and transmission that I'm interested in. To give you some background, I normally tow my Ambassador with my 4X2 2002 Toyota Sequoia with the 4.7l engine. I sometimes tow with my 1970 Chevrolet CustomCamper/20. I normally get 10MPG with either the Sequoia or the Chevy.
My Ambassador weighs in at #5,700 as towed today. There aren't many hills around here, but it pulled up the best example of a hill at 75 MPH. The ride was smooth, quiet and steering very controlled. For a 47 mile loop on US 190 from my shop to Belton and around Stillhouse Hollow, through Harker Heights, it managed 14.0 MPG. I was very impressed.

As noted previously here and elsewhere, the oil temperature runs hotter than most expect. At the top of the short hill we have here, the oil temp rose to 244deg/F on the first climb at 65MPH.

The oil temperature light did not illuminate, so I would guess this is normal. I have yet to find out at what temperature the engine oil temperature light illuminates.
I'll be ordering a new RAM 1500 Ecodiesel soon!

The water temp is more worrisome to me, but I guess time will tell. A really hot day in the SW or pulling some long grades in Colorado in July and August will be telling.

Yes the oil temp is fine, its the water temp that is important here.

Blasting up the hill

Well, I did have the pedal "stapled to the floor" to see if I could get any warning lights to illuminate. No warning lights came on. It held 75 MPH all the way up the hill.
I've asked the salesman to get me some information like at what temperature do the coolant and oil temperature "telltale" warning lights illuminate. I have not been able to find what "normal" operating temperatures are for this engine. All I can say for sure is that at 235F, the engine temperature "telltale" light did not illuminate. With it only being 75F when I took the test tow, it does make me wonder how it would have fared on a hotter day, with a heavier load, on a longer hill. Of course blasting up the hill at 75MPH (posted speed limit) is not how I typically tow

V-6 Turbo diesel for '14 Ram PU

The magical 8-speed... I notice from the tach that it's in a higher gear (or a locked-converter state) at 75 than 65. Both runs in tow/haul?

The transmission temp seems very well-behaved. I guess it doesn't run that through the engine radiator from the 50-degree delta between them.

I note also that at 235 on the EVIC, the coolant temp gauge is only a little above halfway and nowhere near the red.
