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.

Dodge and Jeep recalling 895k SUVs for possibility of headliner fires

Dodge and Jeep are announcing recalls of a total of 895,000 Durango and Grand Cherokee models worldwide from the 2011 through 2014 model years. There's a possibility that the wiring in the sun visor can short circuit and cause a fire. It specifically affects vehicles built between January 5, 2010, and December 11, 2013, and there are approximately 651,000 of them in the US, 45,700 in Canada, 23,000 in Mexico and 175,000 outside of North America.
Screws that fasten the sunvisor to the headliner may pierce wires in the visor, if the part has been removed or serviced, potentially causing a fire risk. If the wires short circuit, they could overheat and potentially combust. The automakers report three injuries caused by this defect, and according to the investigation by the National Highway Traffic Safety Administration, "there may be a total of 52 unique fire incidents."
To fix the problem, Dodge and Jeep will inspect the vehicles for suspect wiring, and all of the models, whether damaged or not, will get a new sun visor spacer with a wire guide to stop the possibility of short circuits. According to the automakers' announcement, "this condition is not present in vehicles which have not had the headliner or vanity mirror serviced." They will notify affected owners, and repairs will begin in August.

Jeep Renegade Hell's Revenge is the Harley rider's Jeep

Well, here's a thing. Yes, it's a Jeep Renegade. Yes, it has flames on it. And no, we aren't really sure how to feel about it. This is the Renegade Hell's Revenge. Presumably named after the Hell's Revenge Trail in Moab, this one-off baby Jeep is the product of Italian tuning house Garage Italia Customs and draws inspiration from the collected works of Harley-Davidson. It's not the first time a car company has attached the Milwaukee icon's badge to one of its vehicles – the company has a long history of partnering with Ford for special edition pickup trucks – but it's the first time we can recall the brand teaming with Jeep. The Hell's Revenge was created because of the 25th annual European H.O.G. Rally, a big Harley-Davidson festival being held in Portoroz, Slovenia this weekend. And since Europeans have a bizarre infatuation with Harleys, Jeep probably saw an excellent advertising opportunity and slotted the off-road brand in as the event's main sponsor. We have to admire the workmanship on this diesel-powered Renegade. Ignore the fact that there's a flame motif, and the actual paint job itself is absolutely lovely. According to FCA's official release, GIC used four layers of matte paint before applying fluorescent paint. The dashboard also gets a bright, exuberant flame motif, while the seats are a combination of Foglizzo Nappa leather and black denim. The functional changes are minor. BFGoodrich tires and a jacked-up suspension provide extra capability, and there are a pair of adorable LED spotlights ahead of the two A-pillars. It's an impressive effort. Really. But when you remember that the last Chrysler product to wear a flame motif was the PT Cruiser, we wonder if Jeep knew what kind of company its newest CUV would be in. Related Video:
