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.

Feds fretting over remote hack of Jeep Cherokee

A cyber-security gap that allowed for the remote hacking of a Jeep Cherokee has federal officials concerned. An associate administrator with the National Highway Traffic Safety Administration said Thursday that news of the breach conducted by researchers Chris Valasek and Charlie Miller had "floated around the entire federal government." "The Homeland Security folks sent out broadcasts that, 'Here's an issue that needs to be addressed,'" said Nathaniel Beuse, an associate administrator with the National Highway Traffic Safety Administration. Valasek and Miller commandeered remote control of the Cherokee through a security flaw in the cellular connection to the car's Uconnect infotainment system. From his Pittsburgh home, Valasek manipulated critical safety inputs, such as transmission function, on Miller's Jeep as he drove along a highway near St. Louis, MO. The scope of the remote breach is believed to be the first of its kind. The prominent cyber-security researchers needed no prior access to the vehicle to perform the hack, and the scope of the remote breach is believed to be the first of its kind. A NHTSA spokesperson said the agency's cyber-security staff members are "putting their expertise to work assessing this threat and the response, and we will take action if we determine it's necessary to protect safety." A Homeland Security spokesperson referred questions about the hack to Chrysler. Fiat Chrysler Automobiles has already been the subject of a federal hearing this month, in which officials scrutinized whether the company had adequately fixed recalled vehicles and repeatedly failed to notify the government about defects. But cyber-security concerns are a new and different species for the regulatory agency. Only hours before the Jeep hack was announced by Wired magazine earlier this week, NHTSA administrator Dr. Mark Rosekind said hacking vulnerabilities were a threat to privacy, safety, and the public's trust with new connected and autonomous technologies that allow vehicles to communicate. NHTSA outlined its response to the cyber-security challenges facing the industry in a report issued Tuesday. In it, the agency summarized its best practices for thwarting attacks and said it will analyze possible real-time infiltration responses. But the agency's ability to handle hackers may only go so far.

The 2018 Jeep Wrangler will look a lot like the 2017 Jeep Wrangler

JL Wrangler Forums suggests the next-generation Wrangler will be restyled in an evolutionary way that maintains the off-roader's classic looks yet adds new features. The forum used intelligence from spy photos and leaked images to assemble renderings of the new Wrangler. They show that the front end is still classically Jeep, but with modern updates. The LED headlights and turn signals revealed in FCA drawings are noticeable changes. An interesting touch is just behind the rear bumper, where there appears to be an air dam for aerodynamics. There's still a gap between it and the front fenders to keep the old-school look intact. The grille, windshield, and hood are also more raked for the sake of aerodynamics. At the back, the lights follow the FCA drawings as well, though the reverse lights from those illustrations appear to be absent. The square taillights are also shown on the truck variant, along with the plastic fender flares of the SUV version. Spy photos of the Wrangler pickup have shown a streamlined box with integrated taillights akin to the Ram, but it's likely to be a placeholder until the final design is selected. The sides of both models also feature more squared-off details in the top and door handles, generally with beveled corners for a more modern look. The top is where things get fuzzy. The new model might lose its removable top altogether, in favor of removable panels similar to the Jeep Renegade. JL Wrangler Forums illustrated how this could work in the above image. The roof can be removed in sections, and the rear-most windows can also be taken out. The overall effect is similar to that of a current Wrangler Unlimited. There is a potential drawback to this system, though. All of these hard panels will have to be left somewhere. And unlike the current model, this one wouldn't have a soft-top back-up when the weather turns. It's hard to say for sure if this design will make it to production. FCA has consistently and effectively hidden this part of its Wrangler prototypes since they were first spotted. At this point, we can only speculate on how the top will function. Otherwise, these renderings seem plausible, and we should know how accurate they are when the Wrangler makes its expected debut next year. The new Wrangler will likely have some aluminum body panels, an 8-speed automatic and an available diesel powertrain.
