Chrysler 3.0L EcoDiesel V6: Autoblog Technology of the Year finalist

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.

2014 Jeep Grand Cherokee Diesel and SRT climb onto stage

This is indeed a case of not knowing how much we wanted something until it arrived. We've been big fans of the Jeep Grand Cherokee ever since the new model arrived a couple of years ago, and while the update you see here might seem just a slight refresh, it's actually much more than that.
For starters, the 2014 Grand Cherokee marks the return of a diesel model here in the States, with Chrysler's new 3.0-liter EcoDiesel V6 under the hood, churning out 240 horsepower and 420 pound-feet of torque, mated to an eight-speed automatic transmission. Of course, all of the Grand Cherokee's usual off-road goodies are on hand, with moderate tweaks to make it an even more capable vehicle when the going gets rough. Both the gasoline-fed 3.6-liter V6 and 5.7-liter V8 get the new eight-speed auto, as well.
The high-performance Grand Cherokee SRT also trudges on into the new model year, with very subtle tweaks found underneath the aggressive, slightly redesigned sheetmetal. The 6.4-liter Hemi V8 also gets eight-speed gearing, which Chrysler says will improve not only 0-60 times, but mid-range performance as well. Bring it on, we say.

2015 Jeep Cherokee finds a bit more fuel mileage thanks to stop/start and aero tweaks

Just a year after it burst onto the scene, Jeep has already made a pretty substantial addition to its V6-powered Cherokee, which has proven to be an extremely popular seller so far for the brand, adding a new stop-start system for the midsize, off-road-ready CUV.
The addition of stop-start included a few aerodynamic tweaks to the Cherokee's polarizing body, resulting in a wallet-pleasing increase in fuel economy. According to the EPA, the front-drive, V6-powered Jeep will now return 21 miles per gallon in the city and 29 mpg on the highway, up from 19 city and 28 highway. Four-wheel-drive, V6-powered Cherokees, meanwhile, will now return 20 mpg in the city and 28 mpg on the highway, up from 19 mpg in the city and 27 mpg.
With 271 horsepower, 239 pound-feet of torque and these newly enhanced figures, it's refreshing to see a larger, naturally aspirated engine that is still able to take the fight to today's crop of small-displacement, turbocharged four-cylinders.
