FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

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.

Jeep recalling 75,000 Cherokees over air-conditioning lines

Fiat Chrysler Automobiles has issued a recall for an estimated 75,364 examples of the Jeep Cherokee in the United States. The problem stems from an air-conditioning line, which may have been installed to close to the exhaust manifold. "Under certain operating conditions," says FCA in the statement below, "this may pose a fire risk." Thus far, however, the company says it is "unaware of any related injuries or accidents." The owners of those 75k Jeeps (as well as another 18,000+ in other markets) can expect to hear from their local dealers to have the problem rectified. However the manufacturer also advises owners to watch out for indicators like air-conditioning loss or a dashboard warning light and contact their dealers if necessary.
