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 issuing software update for 1.4M vehicles to prevent hacking

In the wake of a Jeep Cherokee being hacked remotely while on the road through its Uconnect infotainment system, FCA US is now issuing a software update for 1.4 million vehicles in the United States. Affected customers will receive a USB stick in the mail with the improved version; owners can check this website to see if their cars are affected. A large variety of models with FCA's 8.4-inch touchscreen infotainment system are affected. They include the 2015 Chrysler 200, 2015 Chrysler 300, 2015 Dodge Charger, and 2015 Dodge Challenger; 2013-2015 Dodge Viper; 2013-2015 Ram 1500, 2500, and 3500; 2013-2015 Ram 3500, 4500, and 5500 chassis cab; 2014-2015 Jeep Grand Cherokee and Cherokee; and 2014-2015 Dodge Durango. According to FCA in its announcement, the new software "insulates connected vehicles from remote manipulation." As of July 23, the company also "fully tested and implemented within the cellular network" additional security to prevent access to many of a vehicle's systems. FCA US says that it's conducting this campaign out of an abundance of caution and disputes the notion that there's a defect with these vehicles. Beyond the demonstration of the hack in the Cherokee, the automaker says that it's unaware of any other reports of these attacks actually happening. Related Video: Statement: Software Update July 24, 2015 , Auburn Hills, Mich. - FCA US LLC is conducting a voluntary safety recall to update software in approximately 1,400,000 U.S. vehicles equipped with certain radios. The recall aligns with an ongoing software distribution that insulates connected vehicles from remote manipulation, which, if unauthorized, constitutes criminal action. Further, FCA US has applied network-level security measures to prevent the type of remote manipulation demonstrated in a recent media report. These measures – which required no customer or dealer actions – block remote access to certain vehicle systems and were fully tested and implemented within the cellular network on July 23, 2015. The Company is unaware of any injuries related to software exploitation, nor is it aware of any related complaints, warranty claims or accidents – independent of the media demonstration.

2014 Jeep Cherokee: Introduction

When we look back at some of the more shocking product launches of recent yeras, the Jeep Cherokee is certainly high up on the list. And we aren't just talking about its off-the-wall, polarizing design.
For starters, it brought back the iconic Cherokee nameplate - something Jeep enthusiasts have coveted for ages. But beyond that, it brought a new evolution for the Jeep brand. After all, the Cherokee is car-based - using the same compact platform that underpins the Dodge Dart and Chrysler 200. It has a greater focus on technology and refinement than ever before, in an effort to appeal to a new crop of Jeep customers. And powering it all is a new (optional) V6 engine paired with an equally new nine-speed automatic transmission.
Can the Cherokee's car-based roots still allow for a vehicle that's superb when the going gets tough? Will its design still be a love/hate affair in one year's time, or will it start to blend in? Is the powertrain strong enough to not only support the needs of daily driving and road trips, but blaze a few trails as well? We're aiming to answer all these questions, and more, over the next 12 months. Welcome to the Autoblog long-term garage, Cherokee.
