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.

Weekly Recap: GM scales back as Russian auto market teeters

General Motors' extensive plans to scale back its Russian operations are the latest sign the automotive market in the former superpower is collapsing – and there are few signs of recovery. GM said Wednesday it will stop selling mainstream Chevrolets and shutter the entire Opel brand in Russia. The moves leave GM with a luxury-focused presence consisting of Cadillac and Chevrolet's Corvette, Camaro and Tahoe. The cutbacks will be completed by the end of the year. The automaker will also idle its factory in St. Petersburg and end a contract-assembly agreement with Russian manufacturer GAZ. "We had to take decisive action in Russia to protect our business," Opel Group CEO Karl-Thomas Neumann said in a statement. "We confirm our outlook to return the European business to profitability in 2016 and stick to our long-term goals." GM is the latest automaker to scale back in Russia as the economic conditions, volatile currency and uncertainty over the conflict in the Ukraine all have sandbagged new car sales. Last month, vehicle sales collapsed 38 percent in Russia to 128,298 units, according to the Association of European Business, which records sales. Joerg Schreiber, chairman of the AEB automobile manufacturers committee, didn't even feign optimism in a statement announcing the figures. "The market is entering a very difficult phase now, and February is only the beginning," he said. "Industry sentiment is the next few months will be extremely difficult and the market bottom has yet to be found." The dovetails with industry experts, who predict the Russian auto sector will remain in the doldrums. IHS said earlier this year it expects Russia's sales to slip to just 1.8 million units in 2015, which is a 40-percent drop from 2012. Other News & Notes Chief leads Jeep's Easter Safari stable Jeep is bringing seven attention-getting concepts to Moab for its annual Easter Safari off-roading celebration in Utah, but the Chief is perhaps the standout of the group. It salutes the 1970s Cherokee with a throwback appearance and surfer styling cues. The Chief has a custom modified razor grille made famous by the Wagoneer, and it rolls on 17-inch slotted mag wheels. The surf theme comes in with ocean blue paint, floral cloth and leather seats and a tiki-style shifter handle. Based on the Jeep Wrangler, the Chief has removable sides, a 3.6-liter V6 engine and a six-speed manual gearbox.

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
