An image of the 3.0-liter turbodiesel in the 2014 Ram 1500 EcoDieselThe 3.0L turbodiesel V6 in the 2014 Ram 1500 EcoDiesel earned a slot on Ward's Automotive 2014 10 Best Engines for its power, fuel economy and refinement. In a piece looking at how Fiat subsidiary VM Motor developed the engine, Ward's also makes note of the fact that the same lump goes in diesel versions of the Maserati Quattroporte and Ghibli. They're tuned a bit differently, naturally, with the QP putting out 275 horsepower and 442 pound-feet of torque, the smaller, lighter Ghibli making do with the same number of horses but a lower torque output of 420 lb-ft.

The 240 horsepower and 420 pound-feet put out by the oil-burning six-cylinder in the Ram was tamed with a host of advances, but it appears that Ram hasn't tamed demand: the initial allocation of 8,000 engines was spoken for within three days of the truck going on sale. Head over to Ward's to read the story of how Ram worked out the equation light-duty-pickup + diesel = success.

      I'm a Gm guy and let me tell you before the diesel I loved this truck. I love the technology in the gauge cluster to the center stack. I love the gear shifter knob to the quality of the interior. I love the brutish good looks but then they went and put a economical and fuel efficient diesel in it and I can not see my way to any other truck no way no how! OMG I am a Ram fan!!!!

      It was this same diesel engine that was supposed to be in the 14' CTS......can you imagine that http://m.wardsauto.com/vehicles-amp-technology/after-killing-vm-motori-program-gm-takes-cadillac-diesel-house

        FYI, this engine wouldn't be the same one that was going to be in the CTS. The 3.0 started development while GM and Penske were 50/50 owners of VM. Since then both Penske and GM sold out to Fiat. Fiat added a lot of tech to the upper end of the engine like Multi Jet 2 etc.. If GM would have stayed with the 3.0 idea it most likely would have had the same lower end, but much different power levels because of the tech that Fiat Powertrain Tech added to the upper.

      Dear Jonathan: The headline should have been "Ram/Jeep and Maserati diesel engines has VM Motori roots", especially if you bothered to look and find out that VM diesel have been paired with European Chrysler/Jeep since the nineties -- even longer for Fiat vehicles.

          No, the 3 liter V6 is a new engine (family name:VM A630), it's on the market from a couple of years, and in Europe is sold with Chrysler 300 (rebranded as Lancia Thema), Jeep Grand Cherokee and Maserati Ghibli. The diesel engine used (from many yars) in Wranglers, Liberty (in Europe was called Cherokee), Town & Countri / Caravan (in Europe called Voyager) is the 4 cylinder 2.8 liters (163-200 hp versions), produced by VM (family name VM RA428). The previous Grand Cherokee and the old Commander used a Mercedes V6 diesel 3 liter. Compass and Patriot are still using a Mercedes 4 cylinders, 2.2 liter 163 hp diesel engine, and the Fiat Freemont (Dodge Journey) uses a Fiat 2 liter, 4 cylinders, 140/170hp diesel engine (that will be used also in the european version of the actual Cherokee).

        That's not the general public -- that's dealership sales. It should be interesting how much cannibalization occurs between the light duty diesel 1500 and the HD diesel 2500/3500 trucks.

      As a diesel owner (VW TDI) I can attest to how awesome they are to drive, as well as how they get great fuel economy, but diesel prices in the US are quite high right now. There is a significant delta in the cost ($0.60/gal+) between regular unleaded and diesel. That being said, I'm psyched that RAM was the first to **finally** put a diesel in a 1500 truck. What the heck took so long?!?

        fuel cost is relative to fuel economy. You have to crunch the numbers and figure out your overall monetary benefit for the vehicle.

        Well, they put diesels in the Compass, the Patriot, and the Caliber for export markets, why could they not install a small one in their small vehicles ?

        @fuzzyfish6
        I agree with diesel across the lineup, but this one overkill for the 200, Dart and renegade. I don't think it would fit in those either. Roughly a 2.0l 4 cyl diesel for those and maybe a little larger 4 cyl diesel for the Caravan... like the 2.8l they plan to put in the Wrangler and used to sell in the Liberty.

      It will likely be 2015 before dealerships are able to even have one on their lots for customers to test drive. The Auto industry is a lot like our government, in that they are so out of tune with what we want. For many years consumers have begged for a 1/2 ton diesel and now Ram is surprised that the whole 8000 engine initial allotment was sold in just three days.....really?? Perhaps someone should have thought ahead and gotten enough engines on hand before production orders began. Maybe by 2016 when everyone else has caught up and is offering 1/2 ton diesels.

        I think it's a better business model than dumping a ton of them on the lots only to discount them later. I like the slow roll outs of new product Chrysler is doing. It helps them work the kinks out.

      Fueleconomy.gov pegs the annual fuel cost for a 4wd diesel ram at $2,700. And the annual fuel cost of a 4wd F150 ecoboost at $3,100. Very cool but not earth shattering.

        You totally miss the point. It is simply knowing you are getting fuel numbers in all 20's. It is breaking a barrier and pushing everyone else to up their game. If you just write it off then no one will improve. Obviously many do not agree that is why they are selling like hot cakes.

          There is no need for automaker to outdo each other MPG rating nowadays, really. In the USA, CAFE mandates will take care of that nicely. Many people who bought the ecodiesel RAM is not aware of how much more expansive it is, compares to gasoline powered, to operate a modern diesel powered vehicle in the US, because of EPA related add on. It also ruins the diesel reliability and curve its power output. Get ready to get used to $100-$150 oil change, $50-$100 fuel filter change annually, cost of DEF along side of diesel, expansive glow plug service if living in cold climate (ridiculous when spark plugs can do fine for 100k miles now)....And for the record, the 3.5L ecoboost is putting out 365HP/same torque, the 6.2 Ecotec3 is pumping 420HP/450 lbft....where is the beef from this ecodiesel?

          @SBN This takes 7.7L of oil(about 8 quarts). A hemi takes 7.0L of oil. Again, if you plan on using full synthetics for the hemi engine it's pretty negligible in oil costs.

          • 9 Months Ago
          @Raymond
          @SBN Where you getting your oil changes done??? You're getting ripped off. You do realize this is a 3.0L diesel right??? Not a burly 6.7L like in the larger trucks. Also, most new cars and trucks are requiring full synthetic oil these days, so the cost difference isn't that much different if you're planning full synthetic regardless of which engine you choose.

        If you add any towing Fuel Economy to those numbers, the Diesel's annual fuel cost benefit will be even larger. A recent article of Diesel Power Magazine did a FE test with the Ram towing 7,000lbs. The Ram still almost got 20MPG. That is a huge number. The Ecoboost would have only gotten around 13. That is a 54% difference. http://www.dieselpowermag.com/features/dodge/1403_2014_ram_1500_ecodiesel_vs_2500_sibling_rivalry/

      I give props to Ram for bringing diesel a half ton the market. But why do you buy a diesel truck.....for it's capabilities right? So the numbers on this truck are good but not as good a Ford or GM similarly equipped trucks from Ford and GM will outperform the Ecodiesel in max tow configuration.... Ford 11,300lbs conv towing For the 3.5 EB Ford max payload 3120lbs GM 11,500 and 2010 For the 5.3 V8 As for Ram.... 9200lbs abd 1580lbs The Ecodiesel is a $4500 option, so those that say it had a mpg advantage is correct but it would take 7 years at 20K a year and current gas prices to get your investment back.

        • 9 Months Ago
        @metric91
        I think it depends largely on the buyer. Not everyone will ever tow anywhere close to the max payload of the truck. For instance, when I was shopping around I was aiming for a towing capacity of 6000-8000 lbs as that was all I ever needed (small sports car and tandem axle trailer). So with that in mind, I wouldn't necessarily spring for the strongest of the half tons.

        @metric91
        Actually to be fair you need to compare the price against a comparable engine like the HEMI, not the base 6 cylinder engine. When you do this the price premium for the ecodiesel is $2850 more than the HEMI which is the most fair comparison you can make. This is the exact truck I've wanted to buy for 10+ years...about damn time! But, too late for me as my family has outgrown trucks. If they dropped this motor into a full sized SUV like a Suburban or Armada or Expedition, I'D BUY IT!

        • 9 Months Ago
        @metric91
        this is a good point that many smart buyers consider when buying these trucks. Hopefully the premium for the diesel will eventually come down and hopefully we will start seeing diesel options on all cars and trucks.

        • 9 Months Ago
        @metric91
        you don't understand towing or trucks. I drive 30k a year, so my payback would be 3-4 years. I calculated it out myself, the payback at today's fuel prices would be about 75k miles vs the hemi, and about 150k miles vs the v6. The advantages of diesel are 2 fold. 1 = Low end Torque, diesels make it low, full torque by 2000rpm. This torque is needed to move heavy trailers, the lower the torque, the better it can hold gears and not scream all the time going up grades. 2 = fuel economy while towing. The ecoboost can almost come close with low end torque, but best it with horsepower. But with all that horsepower, it's a real fuel hog while towing. LIke 9-10mpg for a 6000lb trailer. WIth a diesel, you can probably get around 13mpg while towing which is a 30-40% improvement in fuel economy while towing. Paybacks will be much less. The diesel is also now quieter than the gas engine while cruising and accelerating.
