NHTSA still mulling crash tests for recalled Jeeps

Well, no one should ever accuse the government of not giving things plenty of thought. The National Highway Traffic Safety Administration is still debating whether it will retest any of the 1.56 million 1992 to 1998 Grand Cherokees and 2002 to 2007 Libertys that were part of a recall regarding fires after rear-end collisions. And yes, this debate has been going on for over a month. In other news...
The recall dustup started in early June, when Chrysler took the unusual position of refusing a recall request from NHTSA regarding placement of the fuel tank on the effected vehicles. NHTSA said a collision could cause a fire, a position Chrysler took issue with. Extensive negotiations ensued, with Chrysler agreeing to fit certain Jeeps with trailer hitches, which it said would provide some protection to fuel tanks mounted behind the rear axle in the event of a collision.
Part of the issue rests with the amount of data that needs to be processed, according to The Detroit News. NHTSA administrator David Strickland said during a Washington Auto Press Association meeting, "There's a lot of data and Chrysler is being very cooperative in giving us more data." Until that information has been sorted, it looks like re-testing will still be up for debate.

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.

2015 Jeep Cherokee finds a bit more fuel mileage thanks to stop/start and aero tweaks

Just a year after it burst onto the scene, Jeep has already made a pretty substantial addition to its V6-powered Cherokee, which has proven to be an extremely popular seller so far for the brand, adding a new stop-start system for the midsize, off-road-ready CUV.
The addition of stop-start included a few aerodynamic tweaks to the Cherokee's polarizing body, resulting in a wallet-pleasing increase in fuel economy. According to the EPA, the front-drive, V6-powered Jeep will now return 21 miles per gallon in the city and 29 mpg on the highway, up from 19 city and 28 highway. Four-wheel-drive, V6-powered Cherokees, meanwhile, will now return 20 mpg in the city and 28 mpg on the highway, up from 19 mpg in the city and 27 mpg.
With 271 horsepower, 239 pound-feet of torque and these newly enhanced figures, it's refreshing to see a larger, naturally aspirated engine that is still able to take the fight to today's crop of small-displacement, turbocharged four-cylinders.
