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.

GMC boss wants a Jeep Wrangler rival

Challengers come and challengers go, but the Jeep Wrangler continues to push forward even after vehicles like the Toyota FJ Cruiser and the entire Hummer brand have been shut down. Now GMC reportedly wants to take a stab at the quintessential Jeep, as well.
The news comes directly from Buick-GMC vice president Duncan Aldred, speaking with our compatriots over at Edmunds. Although Aldred said there are no plans currently on the table to expand GMC's lineup beyond the current range, "there is plenty of room everywhere in the hierarchy."
That could include a rival to the Wrangler, as well as a flagship luxury SUV positioned above the current Yukon Denali (pictured above). Just when (or for that matter, if) such models might come into fruition remains a big question mark, but it's certainly interesting to see what GM's dedicated truck brand has on the drawing board.

Jeep Liberty under investigation for door fires

The Jeep Liberty has already had plenty of attention for possible fires thanks to the first-gen model's fuel tank, but now the midsize Jeep is under the microscope of the National Highway Traffic Safety Administration for another fire-related concern. NHTSA has opened an investigation for the 2012 Liberty after receiving two reports of electrical fires in the driver's door.
According to the investigation summary, around 80,000 vehicles could potentially be affected by this problem. In both reported fires, the drivers noticed smoke and then flames from the master power window switch, and they had to pull to a stop and exit through the passenger side of the SUV. According to Autoguide, there was one injury to a motorist who suffered burned fingers while trying to open the driver's door.
Interestingly, the Dodge Nitro is not yet involved in this investigation, even though it was still around for the 2012 model year; the Nitro ended production in 2011 about a year before the final Liberty rolled off the line for the 2013 model year.
