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.

Jeep Grand Cherokee SRT gets power increase, minor tweaks for 2015

As a brand within Fiat Chrysler Automobiles, SRT may have an uncertain future, but it's pumping out some seriously mean machines anyway. The supercharged Hellcat V8 may be gobbling up most of the headlines with its 707 horsepower, but even the Grand Cherokee SRT is getting some small updates for the 2015 model year.
Most importantly for many enthusiasts, the Grand Cherokee SRT is getting a slight power bump. Don't expect the 700+ hp from the Hellcat, but this SUV sees a modest 5-hp and 5-pound-feet of torque improvement to bring output to 475 hp and 470 lb-ft for its 6.4-liter V8 with an eight-speed automatic. The minor change doesn't change the sprint to 60 miles per hour, clocking in at the same 4.8 seconds, or the tow rating at 7,200 pounds. Still, more grunt is never a bad idea.
Another new addition is the Active Noise Canceling system as a standard feature for this powerful SUV. It adds four microphones around the vehicle and uses the stereo system to nullify extraneous sound. However, Jeep claims that the meaty exhaust note from the V8 still gets through into the cabin for driver enjoyment.

Jeep Renegade gets new duds courtesy of Mopar

In a uncommon move, Jeep has found itself with customized versions of a car we've become quite familiar seeing on auto show floors well before it's actual on-sale date. But that's okay – we're pretty fond of the little Renegade, and we're even more keen to get behind the wheel, something that's scheduled to take place in just a few weeks. The two Renegade models you see here have been blessed with bits and pieces from the Mopar parts catalog. These Jeep Performance Parts and Authentic Accessories will be made available to buyers of the Renegade who want to add some factory-backed custom flair to their rough-and-tumble baby crossovers, whether they plan to stay on the asphalt or head off the beaten path. Starting on the street, the Urban Jeep Renegade doesn't really have any major modifications, its factory-spec bike carrier, mirror caps, grille rings, taillamp surrounds and roof rails in Omaha Orange paint over an Anvil-color base serving more to make it stand out from the crowd than actually offer any additional capability. The interior of the Urban Renegade also gets Omaha Orange highlights to go along with Katzkin leather seats. On the dirtier side of the crossover equation, the Commando Green off-road Mopar-modded Renegade gets concept skid plate, prototype rock rails, rear valance and production roof rails provide some added protection and carrying capabilities. X-shaped graphics mimic the jerry can-style motif of the Renegade's tail lamps. Inside, Commando Green bits again join Katzkin leather.
