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 recalling 63k Jeeps, Vipers and Ram ProMaster City vans

Fiat Chrysler Automobiles has announced a pair of recalls cover nearly 63,000 vehicles. The bigger of the two actions covers manual-transmission-equipped vehicles from 2006, including the Jeep Liberty and Wrangler, as well as the Dodge Viper. FCA engineers uncovered that the clutch ignition interlock switches use a kind of wire that was part of a previous recall campaign. Because of this, the company said that affected vehicles may not start, although in rare cases, "if recommended starting procedures are not followed," the affected vehicles may lurch forward after turning the key. Those recommended starting procedures "include activating the parking brake, placing the shift lever in neutral and pressing the clutch pedal before turning the vehicle's ignition key." Recall number two affects the company's 2015 Ram ProMaster City cargo and passenger vans. Owners will need to report to dealers to have a piece of tape removed from the side-curtain airbags. The tape is added during assembly and in some cases, may not have been removed. That could prevent the airbags from deploying in the event of a crash. Just under 59,000 vehicles are included in the first recall, including 43,874 in the United States, 11,309 outside of North America, 2,944 in Canada and 706 in Mexico. The ProMaster City recall includes just over 3,900 vehicles. FCA claims it's unaware of any injuries, fatalities or accidents related to either recall and will perform repairs free of charge. Scroll down for the official press release on both campaigns.

The Company will replace their clutch ignition interlock switches at no charge to customers. The action follows an investigation by FCA US engineers that discovered these vehicles are equipped with switches that contain a certain type of wire implicated in a previous campaign. The wire, which was temporarily substituted by a supplier for the specified material, may break. As a result, the vehicles may not start, and in rare cases – if recommended starting procedures are not followed – a vehicle may exhibit unintended movement when its ignition key is turned. FCA US is unaware of aware of any related injuries or accidents involving this population of vehicles.

Consumer Reports digs Mazda3, disses Jeep Cherokee

Consumer Reports has just rendered its verdict on two of the more important cars to launch this year - the Mazda3 and the Jeep Cherokee. Considering the value a "Recommended" rating carries with the public and the viciously competitive markets these two cars compete in, Consumer Reports' view could have some impact on their initial success.
For Mazda, that's a good thing. CR spoke quite highly of the Zoom-Zoom brand's compact sedan and hatch, testing both models, and citing the excellent fuel economy and snickety-snack manual shifter as high points. Downsides to the 3 included a ride that is agile but "nervous," a bit too much noise and a cramped back seat. Still, the 3 was good enough to earn its place in the ranks of the "Recommended."
The Jeep didn't fare quite so well, with CR calling the polarizing CUV "half-baked." Although both engines were tested, the magazine called the 2.4-liter four-pot underpowered and its nine-speed automatic unrefined and unresponsive. That's particularly damning, considering the 9AT's role in future Chrysler products, including the extremely important 200. Overall, the Cherokee missed out on the coveted "Recommended" rating.
