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.

7 months later, Jeep 'trailer hitch' recall still stalled

For the past few years, Chrysler and its CEO, Sergio Marchionne, have gone head-to-head with the National Highway Traffic Safety Administration and its boss, David Strickland, over the government safety agency's request for Chrysler to recall almost three-million Jeep vehicles due to what NHTSA says is a safety issue that has caused at least 51 deaths. After a three-year investigation and Chrysler's initial refusal to issue a recall because it deemed the vehicles safe and built to the day's federal requirements, last summer, the two parties compromised on a "voluntary campaign" to inspect 1.56 million vehicles, those being the 1992 to 1998 Grand Cherokee and 2002 to 2007 Liberty.
Those vehicles were designed with their gas tanks between the rear axle and the bumper, and NHTSA says that in rear-end collisions, damage to the fuel tank has caused fires responsible for those 51 deaths. The compromise reached last summer was that Chrysler would inspect 1.56 million vehicles and, "if necessary, provide an upgrade to the rear structure of the vehicle." Practically speaking, that meant Chrysler would replace aftermarket trailer hitches, but would take no action if a vehicle had a factory-installed hitch or an aftermarket hitch from Mopar.
A report in The Detroit News says the "voluntary campaign" is just now getting under way, with Chrysler saying last week that the design of the replacement part had been finalized and it was tooling up "to deliver the required volume." Seven months later, still in question is whether NHTSA will crash-test the fix engineered by Chrysler, noteworthy because not only did the vehicles in question pass every safety standard necessary to be cleared for sale at the time, there are still questions (to those of us on the outside) as to how the Jeeps at issue fare among their peers in such incidents. Either way, Chrysler and NHTSA apparently still disagree on the efficacy of the remedy itself: the carmaker says it might help in low-speed crashes but not high-speed collisions, a position the NHTSA is at odds with. All of this means the campaign doesn't yet have an end in sight.

2015 Easter Jeep Safari Concepts First Drive

Imagine if once a year your grandmother made a chocolate cake. Not a chocolate cake, that chocolate cake. Blow-your-mind chocolate cake. But she won't ever let you have any – you can only have the spatula and whatever's left over in the mixing bowl. And you don't care. You look forward to that spatula and bowl every year because – "Gadzooks!" – that is some stupendous cake. For us, that cake is the Easter Jeep Safari. An annual pilgrimage to Moab, Utah for a taste of what Fiat-Chrysler's off-road brand has cooked up in its Design Dome. "No, you can't have any," the company tells us, "but you can taste it here, then dream about it until next Easter." In Detroit, Jeep gave us a close look at the seven concepts it built for this year's 49th annual event. Then it went a step further and took those show cars to Mill Canyon, UT, to crawl the red rocks in Jeep's natural habitat. After all, the company calls Moab, "Our home away from home." And it's not true that we never get more than a taste of Jeep's conceptual goodness – 2011's JK8 pickup conversion kit is a slice of Safari creation we can now take home, for instance, as are the hood decals that adorned two of the concepts we drove this year. Pietro Gorlier, President and CEO of Mopar, told us that the evolution of Jeep Performance Parts came from listening to journalists and customers in his first year on the job in 2010. So there's that. But still, we want more cake. Like a full-on production Wrangler Africa. These being one-of-a-kind prototypes traipsing through a canyon of nearly immovable objects, we didn't go fast, we didn't go far, we didn't push hard. But we did drive all the Easter Jeeps, and even just this small taste was outstanding. View 30 Photos Jeep Chief While we listened attentively to the detailed spiels on all this conceptual candy, one question ran through our minds: "How am I going to get in the Chief before everyone else?" And we could see the same thought every colleague's face, those scheming bastards. And why not? The Ocean Blue tribute to the venerable Cherokee of old grabbed everyone's attention since the first teaser images weeks before the event, in part because the vintage truck is up there with mermaids for rarity and lustworthiness. Anything that goes this far in obeisance to that classic Jeep is always going to score huge marks. The Chief is a four-door Wrangler underneath, but in many ways it feels nothing like a Wrangler.
