Next-gen Jeep Wrangler to get 8-speed automatic and 3.0-liter EcoDiesel

Following up on previous reports, an anonymous source within FCA has confirmed to Autoblog that the next-generation Jeep Wrangler will come to market with both a 3.0-liter, EcoDiesel V6 and ZF's critically acclaimed eight-speed automatic transmission. While this pairing makes a lot of sense (we'll explain why in a minute), until now, we only had limited reports that either item would arrive in the next-generation Wrangler. This is the first time we've heard that the eight-speed automatic and the diesel would be paired together. That said, we shouldn't be surprised by this news. FCA currently sells the Jeep Grand Cherokee and Ram 1500 with the diesel/eight-speed gearbox combo, making its inclusion in the next-gen Wrangler far from an Apollo 11-caliber feat of engineering. Naturally, we reached out to Jeep for an official comment. Spokesperson Gabrielle Schulte gave us the expected response to this kind of inquiry, telling Autoblog that FCA does not comment on future product. Jeep has flirted with the idea of a diesel Wrangler for some time, with CEO Mike Manley telling Ward's Auto just over two years ago that a Wrangler diesel was "on the radar," although at that time, we weren't certain whether it'd be the 3.0-liter EcoDiesel showing up in the rough-and-tumble off-roader. As for the eight-speed, SEC filings back in November revealed that it'd be coming to the Wrangler in 2018. Our source could not confirm which model year the 8AT/diesel would arrive in.

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.

NHTSA closes investigation into Jeep Liberty fires

The investigation that the National Highway Traffic Safety Administration opened into the Jeep Liberty in October 2013 has been closed. NHTSA received two (!) complaints about fires starting in the driver's door, thought to be caused by the master power window switch. The initial estimate was that 80,000 Libertys could be roped into a possible recall, but according to a report in the Detroit News the agency examined records for 425,000 Chrysler products that used the same window switch, including the Dodge Nitro and Chrysler Town & Country minivan.
After canvassing 265 warranty claims related to the master switches, NHTSA concluded that the rate of fires compared to the "large population of vehicles" was rather low, and that there was no trend pattern behind the few issues it did find. Perhaps with that, and the closure of the trailer hitch investigation, the Liberty can finally rest in peace.
