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.

NYIAS: 2017 Jeep Grand Cherokee Trailhawk, ooh-rah!

I was very happy to see Jeep offer a stand-alone, off-road-oriented model to the Grand Cherokee for 2017, the Trailhawk. This is not the first time for a GC Trailhawk, as they offered a limited run a few years ago to see if there might be a market for such a model. Looks like there is, as there are Trailhawk models for the Cherokee and Renegade, and now the Grand Cherokee as well. Just to be clear here, Jeep has always offered off-road ready packages (tow hooks, one inch more ground clearance, skid plates) for the Grand Cherokee and Cherokee in the past. They were called "Up Country," or more recently, "Off Road" groups. That was all well and good but, at least where I was living, almost impossible to find. Rarely would you ever find one so-equipped on dealer lots. If you ever saw one on the street, most likely the owner special-ordered it. Having said that, now that I'm living by the beach, I am seeing a few Up Country-equipped older Jeeps; not many, but more than I've seen in the past. As to the new Cherokee and Renegade Trailhawks; I'm seeing a bunch of them. It took a little while for the public to discover this trim level, but now I see them everywhere. Must be the orange tow hooks? Speaking of orange tow hooks... I'm not a big fan of them. Tow hooks for sure, orange ones, not so much; same with the matte black hood decal, not a fan. If I were ever to get a Trailhawk, it would be either dark gray or black, as that effectively hides the hood decal. So Jeep has packaged the Trailhawk as a premium model within each respective model line. While I fully understand the thinking, I do wish Jeep would also offer an entry-level off-road model, one with all the Trailhawk off-road goodness, but minus all the visual and luxury fluff. A lot of off-roaders don't want to pay, or can't pay top dollar for stuff they don't want or need. As to a name, how about "Trail," that being Trailhawk minus the "hawk;" or perhaps "Pioneer?" That's an old name from Cherokees of yesteryear. Back then the Pioneer was positioned as a mid-low level model. I think either name would work well for a back-to-basics-off-road-focused Cherokee and/or Renegade. Content it like the current entry-level Sport or mid-level Latitude models, but include the Trailhawk's off-road prowess. The Grand Cherokee should probably pass on that suggestion, as it would run counter to that model's high-end image. Related Video: Image Credit: Jeep Jeep open road
