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 first American carmaker to return to Tokyo show

Despite foreign-brand car sales in Japan declining six percent in the first four months of this year, Jeep sales are up 21 percent in the same period. That could explain why Jeep will be the first the US manufacturer to return to the Tokyo Motor Show after eight years away. Ford, General Motors, and Chrysler walked away during the global crisis that struck after the 2007 show. Jeep will be part of an eight-vehicle, four-brand showcase overseen by Fiat Chrysler Automobiles Japan, the local subsidiary. For the moment, it is the only US brand to sign up - neither Ford, GM, or even Chrysler are committed to attend. Stablemates Fiat, Alfa Romeo, and Abarth will be there, along with 13 other foreign makes, answering the "Technology & Fantasy" theme for this year's event. In total, organizers announced 15 brands from 14 Japanese manufacturers, and 27 brands from 17 foreign carmakers. The show opens to the public from Oct. 30 to Nov. 8. Related Video:

Jeep Wrangler Polar is a tasty frozen treat

Perhaps it's because we've seen so many kitted-out examples over the years, but it seems to us that the Jeep Wrangler tends to wear its special-edition duds better than most models. It might be the icon's familiar rectilinear proportions or the inherent bolt-on look of its extremities - bumpers, mirrors, lighting, and step rails - but we've seen precious few factory specials that look anything but excellent.
Case in point: this new Jeep Wrangler Polar unveiled at the Frankfurt Motor Show. This European-market limited-edition model is said to be a celebration of winter driving, which evidently works out to a body-color hardtop, black-accent seven-slot grille, 18-inch gloss black wheels, Trac-Lok limited-slip differential and a hard hat for the spare tire. Finished here in Hydro Blue (Billet Silver Metallic and Bright White are also available) and a black interior with Polar White accents, the Polar edition features badges displaying 78° S and 106° E longitude and latitude coordinates for Vostok, Antarctica.
This new Jeep will be available in both standard and Unlimited formats with either the 3.6-liter Pentastar gas engine or the still-not-for-US 2.8-liter turbodiesel when it bows early next year. For further details, check out our gallery above and the press release below.
