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.

Chrysler recalls 2013 Ram pickups, 2014 Jeep Grand Cherokee

Chrysler's spate of successful products is about to be marred by a trio of recalls. The Pentastar is recalling 51,477 Ram trucks and Jeep SUVs. According to the National Highway Traffic Safety Administration, there have been no reported accidents, injuries or deaths related to the affected vehicles.
The largest action covers the Ram 1500, which is seeing 45,961 trucks being recalled. Models built between June 26, 2012 and February 5, 2013 are being recalled due to a potential software issue in the electronic stability control. Apparently, the system can be randomly deactivated upon vehicle startup.
Chrysler is also recalling 4,458 2014 Jeep Grand Cherokee models. Covering everything but the SRT models, the potentially defective SUVs were built between January 14 and March 20, 2013. This recall focuses on "premium headlights," which means cars equipped with LED running lights. During the switch from the bright daytime running lamp setting to the low-intensity parking light setting, an electrical spike can cause one of the Jeep's computers to go into a safe mode, turning off the LEDs. This violates Federal Motor Vehicle Safety Standards.
