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.

New Jeep Wrangler caught nearly uncovered

Finally, after months of seeing Wrangler prototypes carefully covered up, we get a look at some prototypes with the bare minimum of camouflage. Starting from the front, the fascia looks just as it did in previously leaked images. In contrast to the outgoing model, the trademark grille slots are now taller, stretching nearly to the top of the grille surround. The headlights also intersect with the grille slots, resulting in slightly pinched slots at either end. Aside from the grille, we can get a clear view of the new horizontal, fender-mounted turn signals and the traditional exposed hood latches. Moving along the SUV, we find hinges at the base of the windshield, which seems to confirm that you'll still be able to fold it down for maximum wind exposure. And, as we've seen before, the doors have exposed hinges that indicate the doors can come off, too. We can also see that the Wrangler will be offered with both contrasting black plastic fender flares, and with body-colored versions. But unlike past models, the body-colored examples aren't completely painted, leaving a black strip along the edges. Interestingly, the fender vents seen on another fully exposed example of the Wrangler don't appear to be present on these prototypes. They could be covered, or they may be an optional appearance item. At the back, we now get to see the Wrangler's new taillights, which are LED units with an I-beam shape. The exposed gas filler cap is now gone, in favor of a permanently attached filler door. Both the license plate mount and rear window wiper have been moved, too. The license plate now mounts to the bumper, and the rear wiper hides at the base of the rear window behind the spare tire. The rear bumper also gets some red lenses that could simply be reflectors, or possibly rear fog lights. As previously reported, the new Jeep Wrangler is expected to make its debut at this year's LA auto show, with the first deliveries arriving to dealers not long after. It will be available with either a four-cylinder or V6 at launch, with a diesel coming later, and the truck sometime after that. Other new features to the Wrangler could include a roof with power sliding panels, and full-time four-wheel drive. Related Video:

2018 Jeep Wrangler will have an aluminum hood and doors, leaked memo says

Earlier this year, FCA CEO Sergio Marchionne revealed that 2018 Jeep Wrangler would feature a heavy dose of aluminum, though he didn't specify how. Now, JL Wrangler Forums says the Wrangler will use the material for the hood and the doors, citing an internal bulletin from aluminum supplier Alcoa. According to the forum, the company says the next-gen Wrangler will utilize Aloca's C6A1 (an internal name) high form alloy. The SUV will also get 6022 and A951 from Alcoa that will be used on the SUV's front and rear doors, as well as for the hood. Alcoa's C6A1 is the company's new high form alloy, while its 6022 alloy sheet can be found on things like a car's hood, door, or closure panels. Alcoa's A951 is the company's pre-treatment aluminum sheet bonding technology that it uses on automobiles. "A team in the Farmington Hills (Michigan, USA) Aerospace and Automotive Products group is leading a new profitable growth opportunity with the 2018 Jeep Wrangler program. The next generation Jeep becomes the first to utilize our C6A1 high form alloy; we are currently the only supplier of this high form product. Alcoa will also supply 6022 and A951, including front and rear door inners, hood outer and inner." As Marchionne pointed out earlier this year, the 2018 Wrangler won't be made entirely out of aluminum. So Alcoa's contribution to the upcoming SUV's doors and hood could be the only components that use the lightweight metal – or Jeep could be using another aluminum supplier for other parts. Large changes lie ahead for the 2018 Wrangler, which include a pickup version, new engines, and aluminum. But we do know that the next Wrangler is that it will be built in Toledo, OH, as FCA announced plans to spend $1.05 billion to retool the Wrangler factory, while also adding another site in Illinois earlier this year.
