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.

Jeep recalls 92k Grand Cherokee SUVs over electrical issue

According to the National Highway Traffic Safety Administration, Chrysler is recalling 91,559 Jeep Grand Cherokee SUVs from the 2014 model year due to some serious electrical issues. All of the affected models were built between January 8 and August 20, 2013.
The NHTSA report states that, "Due to a disruption of computer communications and loose alternator ground wires, the affected vehicles may experience random illumination of multiple instrument cluster warning lights, loss of cluster illumination and loss of anti-lock brake system (ABS) and electronic stability control (ESC) function." The loss of ABS or ESC would greatly reduce a driver's ability to control the vehicle if things get squirrely, and since these failures would not be illuminated on the dashboard display, drivers would not be warned of the issue, increasing the risk of a crash.
The recall is expected to kick off sometime this month. Chrysler will notify affected Jeep owners and dealerships "will update the ABS and instrument cluster module software and tighten the alternator ground wire," according to NHTSA.
