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.

FCA recalls 894k total vehicles worldwide in two campaigns

FCA is recalling a total of 893,698 vehicles worldwide in two campaigns to fix problems with inadvertent airbag deployment, failure of the anti-lock brakes, and stability control systems in the Jeep Grand Cherokee, Liberty, Dodge Journey, and Fiat Freemont. 559,703 of these vehicles are in the US. The larger recall affects 284,089 examples of the 2003 Jeep Liberty and 2004 Jeep Grand Cherokee, and there are also 13,411 of them in Canada, 6,277 in Mexico, and 48,212 outside the NAFTA region. Because of "electrical noise beyond the tolerance of the airbag electronic control module", part of that component can fail, according to the National Highway Traffic Safety Administration. This can cause the front and side airbags to deploy and the seatbelt pre-tensioners to activate inadvertently. FCA US has seven reports of alleged injuries from this problem. To fix the situation, the Jeeps need their Occupant Restraint Control modules replaced, as well as the front- and side-impact sensors. According to the NHTSA, the replacement parts won't be available until early 2016. Still, FCA US will advise owners about the problem in a letter by the end of December and will send a second notification when the components are ready. The second campaign affects 275,614 examples of the 2012-2015 Dodge Journey in the US; plus 78,148 of them in Canada, 36,471 in Mexico, and 151,476 left-hand drive units outside of NAFTA where it's sold as the Fiat Freemont. On these vehicles, water intrusion can disable the anti-lock brakes and electronic stability control, although a warning light often illuminates when this issue occurs, and the problem doesn't affect regular braking. There are also no reports of injuries or accidents. To fix the issue, dealers will seal the ABS wiring harness and will replace any already affected components as necessary, like the ABS module or the headlamp and dashboard wiring harness. Statement: Occupant Restraint Control Modules October 30, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 284,089 older-model SUVs in the U.S. to replace their Occupant Restraint Control (ORC) modules and front and/or side-impact sensors, as required. Within this vehicle population, FCA US became aware of seven injuries caused by inadvertent air-bag deployments and advised NHTSA accordingly. The affected vehicles are not equipped with Takata Corp. air-bags. The Company is unaware of any related accidents.

Jeep Wrangler Polar Edition coming to America

Jeep originally took the wraps off its Polar Edition Wrangler at the Frankfurt Motor Show in September, and at the time, we figured this would be a Europe-only affair. (Perfectly fine, since we US customers haven't exactly been lacking special edition Wrangler models over the years.) But now, and as Jeep says, just in time for winter, the automaker has announced that the ice cold Wrangler will be hitting North American showrooms in November.
Based on the Wrangler Sahara model, the Polar Edition can be had in either two- or four-door body styles, with a unique Hydro Blue paint job as the featured color. (Buyers can also opt for less-special Billet Silver and Bright White hues.) Other exterior enhancements include a body-colored hardtop, 18-inch gloss black wheels, the Powerdome (power bulge) hood, and unique decals all around the body.
But the Polar Edition isn't just about some paint and stickers. Jeep has fitted this Wrangler with a Dana 30 front axle and Dan 44 rear axle, as well as the Trac-Lok anti-spin electronic rear differential. Like all US-spec Wranglers, the Polar Edition uses Jeep's 3.6-liter Pentastar V6, producing 285 horsepower and 260 pound-feet of torque. Both a six-speed manual and five-speed automatic transmission are available.
