Chrysler’s 3.0-liter EcoDiesel V-6 engine specs

3.0-liter EcoDiesel V-6 engine Specs: 

-240 Horsepower

-420 lb-ft of torque

-Oil change interval - 8,000 to 10,000 miles

-Reduced noise, vibration and harshness (known in the industry as "NVH") so you know you're driving a luxury SUV and not a dump truck!

-Lower compression contributes to a cleaner burning engine while producing more power. 

Offering a diesel engine in an American pickup is anything but new – Ford, General Motors and Chrysler all offer excellent and almost impossibly powerful oil-burning engines in their various fullsize trucks. What is new and novel about the 3.0L EcoDiesel, though, is its size, and the variety of vehicles that use it. It's the smallest engine, as far as displacement is concerned, currently offered in a large truck in the US, and, for 2014 and 2015, it is available in the Ram 1500 and the Jeep Grand Cherokee.

Though it may be small, it's got muscle. While 240 horsepower isn't particularly impressive these days, the engine's 420 pound-feet of torque more than makes up for that. The torque rating is even greater force than even the big 5.7-liter Hemi can muster. Chrysler's well-regarded eight-speed automatic transmission makes the most of all that bull-headed pulling power in both the Ram and Grand Cherokee. Chrysler claims the Ram EcoDiesel 1500 can tow as much as 9,200 pounds when properly equipped, which makes it "90-percent of the Hemi with a night and day difference in fuel economy."

Make no mistake; it's that promise of a sizable fuel economy improvement that many long-haul truckers will be most interested in. In the Ram 1500 that we tested for our Tech of the Year competition, the diesel engine costs $2,850 more than the gas-fed V8, and Ram estimates that EcoDiesel buyers will pay off their investment when compared to the Hemi engine in less than three years, which is considerably less time than the 4.5 or so years the average buyer will keep his or her fullsize pickup. The more you drive, the more you'll save, and the math proves equally as effective in the Jeep Grand Cherokee.

Put simply, the diesel engine will save its operator money by reducing fuel costs at the pump. Smart move, Ram. 

The EcoDiesel’s fuel pump is upgraded to accommodate the engine’s 2,000-bar (29,000-psi) high-pressure common-rail injection system. The engine also benefits from Fiat’s MultiJet 2 technology, which enables Injection Rate-Shaping – fuel injection that is modulated to mitigate noise and improve low-speed throttle response, while reducing fuel consumption and emissions.

The system’s high-dispersion nozzles and advanced-technology servovalve can accommodate up to eight fuel-injection events per cylinder cycle.


The EcoDiesel V-6 is available in the 2015 Ram 1500 full-size light-duty pickup and the mid-size 2015 Jeep Grand Cherokee, the most-awarded SUV ever. Equipped with the EcoDiesel, the Grand Cherokee’s 7,200-lb. tow rating is unsurpassed in its class – matched only by the Grand Cherokee powered by Chrysler Group’s celebrated 5.7-liter HEMI V-8.
