Federal investigations about safety of rear-mounted gas tanks is nothing new

The National Highway Traffic Safety Administration and Chrysler are currently making waves in our daily news feeds due to a disagreement over the safety of a few million Jeep Liberty and Grand Cherokee models. Specifically, NHTSA has asked Chrysler to recall the SUVs because of the location of their fuel tanks, but you may be interested to know that requests such as this are nothing new.
Besides the two Jeep models, NHTSA has launched investigations over the years in such models as the Ford Crown Victoria (and its police-car counterpart), GM pickups built between 1972 and 1987, and rather famously the Ford Pinto.
Understanding how automakers and NHTSA have dealt with fuel-tank-safety concerns in the past may offer a better understanding of how Chrysler and the government agency will settle their current dispute. Check out the complete article from The Detroit News here.

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 Renegade Trailhawk [w/video]

There are two avenues to the world of off-roading. Arguably the more popular is to pick up a second- or third-hand Jeep, Land Rover or pickup truck and go wild with the aftermarket. The opposite approach, though, is to simply buy new, which brings a warranty along with the most up-to-date off-road tech fitted by the factory (despite likely lacking the ultimate capability of an aftermarket-imbued vehicle). That second option has, traditionally, been pricey. Take our long-term Jeep Cherokee Trailhawk, which rings up at just over $38,000. A Ford F-150 SVT Raptor is going to be an even more expensive proposition, while the undisputed kings of luxury off-road performance from the factory – the Range Rover, Toyota Land Cruiser and Mercedes-Benz G-Wagen – will require ownership of a medium-sized oil well. With all due respect to those who take their Trail-Rated Jeep Patriot models off-road, the all-new Renegade Trailhawk is such an exciting proposition because it brings the cost of a warranty-backed off-roader down significantly, while also delivering a degree of trail-rated performance that should easily fulfill the needs of the average enthusiast. Drive Notes Before we get into what it adds, it's worth noting that the Trailhawk trim does have a small impact on the Renegade's on-road abilities. As we said in our original feature, the TH adds a significant amount of weight to the standard CUV, as it tips the scales at nearly 3,600 pounds. That mass, combined with the slightly higher stance, means the off-road model doesn't handle quite as well as a lesser Jeep. It also doesn't feel as fleet of foot, as it retains the same 2.4-liter, 180-horsepower four-cylinder and nine-speed automatic found throughout the Renegade range. Despite the downers, the Trailhawk trim does bring quite a lot to the Renegade package, most notably in the form of a bespoke version of Jeep's Active Drive all-wheel-drive system. The upgraded system features a dedicated 20:1 crawl ratio while the Selec-Terrain system is home to a new Rock setting. Beyond that, Jeep lifted the Renegade's ride height eight-tenths of an inch, increasing overall ground clearance to 8.7 inches and delivering 8.1 inches of wheel articulation. This is complemented by unique front- and rear-fascias, which up the approach and departure angles to 30.5 and 34.3 degrees, respectively, besting the Cherokee Trailhawk's 29.8 degrees and 32.1 degrees.
