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.

Daily Driver: Long-Term 2014 Jeep Cherokee

As a fan of the boxy Jeep styling of old, I was disappointed when photos first leaked of Jeep's revived Cherokee in early 2013. Then the midsize crossover arrived in Autoblog's longterm garage in May of 2014 and my opinion did a 180. I was prompted to rethink the exterior design of the vehicle after reading our reviewer's interview with head Jeep designer Mark Allen. "The previous, blocky Cherokee was so aerodynamically inefficient, it would be wrong to do it," Allen told Autoblog's Jonathon Ramsey. That made sense. After all, Jeep is a brand associated with the outdoors, so its only natural that they seek to produce efficient, yet capable vehicles. It was then I began reconsidering the sleek lines of the new Cherokee. What once seemed bland and rounded now appeared streamlined and purpose-built. I also give Jeep credit for the slim headlamp silhouette, which look like no other SUV on the market – a far cry from the distinct circular lamps on Wranglers or squared headlights of past XJs. As I drove our long-term Jeep Cherokee Trailhawk on a few road trips, my affinity for the vehicle's comfortable interior grew as well. The seats held up to a nine-hour trek to Montreal, and the Chrysler Uconnect system made navigating the roads and the radio a breeze. Above you'll hear my early impressions of the Cherokee, and below you'll find a previous long-term update featuring Autoblog's Steven Ewing and Chris McGraw. UPDATE: The video mistakingly indicates that the Jeep Cherokee features LED headlights. The Jeep Cherokee, in fact, has daytime running lamps with LED accent lighting. Related Video:

Jeep Cherokee Trail Carver is a more rugged Trailhawk

We briefly mentioned the Jeep Cherokee Trail Carver that was heading to SEMA last week when discussing the Mopar lineup set to be shown in Las Vegas. At the time, though, we weren't able to dive too deeply into details. But with SEMA in full swing, we were able to sneak over and grab some snaps of one of the first modified Cherokees we've seen. The Cherokee is, after all, kind of an unknown quantity in the modification department, being so new and featuring such a polarizing design. We were quite interested to see what Mopar could come up with.
Starting with the Trailhawk 4x4 and its 3.2-liter V6, the engine is fitted with a Mopar cold-air intake and a new exhaust, although it's not clear what sort of power boost has resulted. We'll admit, we were hoping Jeep and Mopar would get a bit more aggressive with the Cherokee's suspension (has anyone thrown a few-inch lift on the new Jeep yet?), but there's no mention of upgrades beyond the knobby, off-road tires. Those should do some good when the going gets rough, while rock rails are there to protect the Auburn Pearl paint on the body.
Speaking of that paint, it's complemented by an interesting graphics package in contrasting black and Crush Orange. The cabin sports Katzkin Amaretto leather seats, along with tech-friendly items like a wireless charging system for cellphones and wireless internet.
