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 defies NHTSA, says it won't recall 2.7M Jeep Grand Cherokee, Liberty models

Facing a possible recall totaling around 2.7 million of its most popular SUVs, Chrysler remains insistent that the 1993-2004 Jeep Grand Cherokee and 2002-2007 Jeep Liberty are safe vehicles. This comes on the heels of a recall request from the National Highway Traffic Safety Administration for these two models due to fuel tanks mounted behind the rear axle, which could possibly be ruptured during severe rear-end collisions, leading to an increased risk of fire. In response to the allegations, Chrysler says that it does not agree with NHTSA nor does it plan on recalling either vehicle.
Chrysler said both SUVs "met and exceeded" the requirements for fuel-system integrity, and cooperated fully with NHTSA since the investigation was opened in 2010. While 15 deaths and 46 injuries have been reported from fires caused by rear-end collisions on these models, Chrysler is claiming that the vast majority of incidents cited by NHTSA were "high-energy crashes," including one where a stopped Grand Cherokee was rear-ended by a tractor trailer going 65 miles per hour.
The automaker wraps up by saying "NHTSA seems to be holding Chrysler Group to a new standard for fuel tank integrity that does not exist now and did not exist when the Jeep vehicles were manufactured." Scroll down for Chrysler's official response to NHTSA, but we're pretty sure this isn't the last we've heard on this issue.

Chrysler axes old V6s, goes all-Pentastar

Old technology has a way of lingering on, particularly at Chrysler headquarters in Auburn Hills. So while the Pentastar V6 has replaced the older engine architecture in just about every application, it still soldiered on in some export markets. But the introduction of a new 3.0-liter Pentastar V6, produced in Michigan and meant only for the Chinese market, has put the final nail in the old engine's coffin.
Fitted into the 2014 Jeep Grand Cherokee and Jeep Wrangler just introduced to China at the Chengdu Motor Show, the downsized six uses the same architecture as the larger 3.6-liter Pentastar V6. But because of its 2,997cc capacity, it can be exported to China without the increased duty the 3.6-liter or even 3.2-liter Pentastar engines would incur. The 3.0-liter V6 develops 230 horsepower at 6,350 rpm and 210 pound-feet at 4,400 rpm.
Admittedly, it's unlikely, but even though the engine was said to be created solely to undercut tax thresholds in China and Europe, the 3.0-liter Pentastar has recently surfaced in rumors of an application here: as the boosted heart of a potential Cherokee SRT with anywhere from 375 to 410 hp.
