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.

Car Club USA: Louisiana Mudfest

There's nothing quite like mudding. Big tires, huge power, and crazy-wild gearheads that like to throw down on a mud pit almost as much as a thirty rack of Coors. In the latest, and some might argue greatest yet episode of Car Club USA, we head to Louisiana to throw some dirt at Mudfest. As Louisiana's one and only Mouth of the South puts it, "If you don't mud ride... go to Texas I guess." Joining The Mouth and friendly rivals The Most Hated Mud Sluts, we dive in. Beyond the obvious V8 blasting and tractor-tire spinning, those who know best describe Mudfest as, "Good cooking, good friends, good fun, and a lot of partying." It's a motorsport spectacle unlike any you're likely to find up North or out West, though no less impressive to behold. Follow along with the fun, the impromptu drag racing, the trash talking, and the mechanical madness. And find out why, at Mudfest, "if we don't tear it up, we ain't done it right." Each Car Club USA episode features a different car club or event from across the US, where passionate owner communities gather to share automotive experiences and embark on incredible adventures.

Jeep Cherokee sales rival Wrangler after two months

In our First Drive article on the 2014 Jeep Cherokee we said, "our informal and thoroughly unscientific opinion is they're going to sell tons of them. Why? Because it is very good." So far, it appears the public concurs. Of course, it's very early - the new compact utility has logged just one month of confirmed sales, but Larry Vellequette at Automotive News says dealers have told him that the second month of sales will be even better, a message that mirrors what we've heard from company execs.
In its first, severely truncated month on sale, the Cherokee sold 579 units. With all of November to play with, though, dealers moved 10,169 of them - compared to 11,753 Wranglers and 14,798 Grand Cherokees. That helped propel Jeep to a 30-percent year-on-year improvement for the month, Chrysler Group to a 16-percent improvement and the group's 44th consecutive month of sales growth, exceeding analyst expectations in posting its best November numbers since 2007.
If it can just keep replicating the its first month of sales, the finalist in North American Truck of the Year voting will smoke the trade done by the outgoing Liberty, which didn't break 7,900 units in a month in the last four years of its life (and normally didn't get close to even that). In March this year, Chrysler said it wants to build 250,000 Cherokees in its Toledo assembly plant for global sales. It's early yet, but with second-month sales quoted as being as "strong as death," the bookies might be resetting the odds.
