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 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.

Chrysler recalling over 200k vehicles across its brands

With more than 200,000 units across six separate recalls and almost all of its brands, it appears that Chrysler has officially jumped headfirst into the recall pool this month. The National Highway Traffic Safety Administration has issued three official recalls for the automaker, and The Detroit News is reporting that the automaker itself has announced three more.
The biggest of the recalls applies to about 120,000 Dodge Charger, Dodge Challenger and Chrysler 300 models for 2011 and 2012 due to faulty wiring harnesses for the seat-mounted side airbags, which could lead to these airbags not deploying in the event of a crash. A little more than 60,000 two-wheel-drive versions of the 2007-2008 Dodge Nitro and 2008 Jeep Liberty SUVs are being recalled due to a heat shield that could cause the driveshaft to break, which if that isn't bad on its own, could then hit underneath where the airbag sensor is mounted, causing the airbags to deploy. Wrapping up NHTSA's recall notices, about 20,000 Jeep Patriot and Jeep Compass models for 2012 are also being recalled due to a problem with the fuel tank transfer tube that could lead to the vehicle stalling. The LX car recall campaign is going into effect this month, while the other two will start next month - all three notices are posted below.
In addition to the official NHTSA recalls, The Detroit News is also reporting that Chrysler is recalling more than 16,000 Ram trucks and a small number of Dodge Dart sedans. Around 6,500 2013 Ram 1500 trucks will be recalled due to an improper adjustment of the parking brake cable from the factory, while 7,000 Cummins-powered 2013 Ram Heavy Duty trucks are being recalled due to an engine cover that does not have as much heat resistance as it is supposed to. Finally, a total of 46 Dodge Dart sedans are being recalled due to a problem with the brake calipers and/or parking brake.
