The 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.
