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 gives a trio of customs an encore showing at SEMA

While Jeep certainly had some new customs on display at this year's SEMA show, it wasn't afraid to recycle a few that people might have missed from earlier this year. The maker of many beloved off-roaders already displayed the Jeep Cherokee Dakar, Maximum Performance Wrangler and Wrangler Mojo at the 2014 Easter Safari, but they all made it to SEMA for an encore.
Based around the Trailhawk, the Cherokee Dakar (pictured above) imagines an even more off-road-capable version of the crossover. The concept wears a mix of Silver Steel Stain paint with Flame Red graphics and rides on 17-inch wheels wrapped in 33-inch BFGoodrich Mud Terrain tires. To back up the rugged look, the Dakar is fitted with rock rails and skid plates protecting the oil pan, front suspension, fuel tank and other underbody parts. It also sports prototype parts from Jeep Performance Parts, including a lift kit and fender flares.
The Wrangler is one of the paragons of off-roading, and as the name suggests, the Maximum Performance Wrangler concept is meant to be the ultimate example of what it can do. The custom features locking Dana 60 axles front and rear, a 4:1 Rock-Trac transfer case, prototype 4-inch lift kit and 37-inch Mud Terrain tires over beadlock wheels. To stay on the trails well into the night, a bar of LEDs is mounted above the windshield. And finally, the Mopar Blue exterior kind of makes the vehicle look like the world's toughest blueberry.
