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:

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.

Off-roader plows through a deep bog like it was nothing

The Facebook page Jeeps With Attitude runs a weekly series called Too Deep Tuesday wherein they post videos of off-roaders running their rigs through bogs and mud holes of surprising depth and coming out the other side soggy but relatively unscathed. This week's video, in which a driver extracts a buried vehicle from the muddiest bog in the land, is the perfect mix of nutso bravery and off-road know-how. The video starts with the vehicle already sunk to its hood and listing to starboard in a deep, sticky bog. Slowly but surely, the vehicle creeps forward through the mud, pushing a heavy bow wave of muck and debris in front of it. Unlike other recent videos where jeep drivers lost their rides in the water and destroyed their expensive toys, this driver keeps his cool and with a steady foot on the accelerator and the help of a winch and a convenient tree, eventually emerges triumphant. What did he do right? Well, using the vehicle's winch to help pull the rig out of the mud was the big thing. Also, he kept his cool and, once committed, never hesitated or deviated from his chosen path. Gunning it blindly or backing up in that mess would have meant almost certain death for that vehicle, a lesson that the aforementioned Jeep drivers learned the hard way.
