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:

Chrysler highlights Mopar lineup for SEMA

SEMA is all about aftermarket parts, and in Auburn Hills that all comes down to one name: Mopar. After having previewed its lineup for this year's Vegas tuner expo earlier this month, Chrysler has now revealed what may not quite be its full dossier of modified show cars, but a good portion of them.
All told Mopar is preparing 20 vehicles for display at SEMA this year. Among them you'll find the Ram Sun Chaser, a 1500 Quad Cab show truck kitted out in two-tone orange and black paint, a roof rack for surfboards, onboard shower and convertible tailgate. The white Fiat 500L is called the Adventurer and is modified for a more rugged look that could hint at the upcoming crossover version. The Jeep Cherokee Trail Carver upgrades on the Trailhawk package with everything from roof basket to rock rails. To counterbalance the off-roaders, there's also a modified Chrysler 300S with a deep black paint job, special grille, Varvatos-edition wheels and more.
All four concepts details so far have Katzkin interiors as well, and there's also an unspecified Dodge Durango with a storm-trooper look in the gallery above. But for more details on what Mopar has installed on the Ram, 500L, Cherokee and 300, you'll want to delve into the press release below.
