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.

Jeep Wrangler Willys Wheeler wants mountains, not a stage

We've said it before and we'll say it again - while we usually grow tired of the endless barrage of special edition vehicles, that isn't the case with the Jeep Wrangler. Every unique model we encounter seems cooler than the one before it, and this Willys Wheeler Edition is no exception.
The Willys Wheeler package is sort of a throwback to early Jeep CJ models, and wears "Willys" stickers on the hood. There's also a gloss black grille, rock rails to protect the side sills, and unique 17-inch black wheels wrapped in meaty BF Goodrich KM Mud Terrain tires. For proper off-road prowess, this special edition uses a Dana 44 rear axle with a limited-slip differential and a 3.73 final drive ratio.
Look for the Willys edition to hit dealerships early next year, starting at $25,795 for the two-door version and $29,595 for the four-door. Feel free to read all about it in the press release below.

Jeep spied testing Hellcat-powered Grand Cherokee Trackhawk

The Jeep Grand Cherokee Trackhawk is coming. We know this, because Mike Manley, the head of Jeep, said so. We showed you this brief spy video a while back, but now we have our clearer images of the Trackhawk undergoing testing. And it looks just like a normal Grand Cherokee SRT. Yeah, anti-climactic, we know. The four shots we have show a bit of camo over the front bumper and grille, likely concealing a tweaked design or visible bits of the 6.2-liter, supercharged V8. It looks like there's a rather substantial opening below the upper grille, almost like a ram-air system. There's also a smidge of what looks like tape on the front wheel arches, although this might not mean much of anything. What's interesting is what isn't here. There's no perceivable change to the back of the car. The exhaust pipes look like they're about the same size, there's no noticeable changes to the aerodynamics, and in fact, there's not even any camouflage. Jeep also hasn't updated the Grand Cherokee Trackhawk's hood, which is somewhat surprising considering the changes for every other Hellcat-equipped vehicle (concepts included). You can check out our earliest look at the Trackhawk up top. As for when this monstrous Grand Cherokee will debut, we're expecting it to arrive sometime in 2017, perhaps on FCA's home turf at the Detroit Auto Show. Related Video:
