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.

Project Trail Force Jeep Wrangler goes to SEMA, then to a lucky winner

Extreme Terrain is an aftermarket parts company focused on the Jeep Wrangler. Partly just because it's a really cool thing to do, and probably having something to do with Jeep's upcoming 75th anniversary, Extreme Terrain found some dance partners to help work up a special 2015 Wrangler Rubicon that it will show off at the Bantam Jeep Heritage Festival in Butler, PA, then at SEMA in November, where it will be given away. Extreme worked with Barricade Off-Road and Kevin Tetz from the Spike show Trucks! to build the Wrangler it calls Project Trail Force. There is more than $24,000 worth of aftermarket gear on it, starting with the Ripp centrifugal supercharger that pumps an additional 140 horsepower into the 3.6-liter V6. It's got a 3.5-inch lift kit from Rock Krawler, Dana 44 axles strung between 37-inch BFG tires, Barricade bumpers, a 9,500-pound winch, fender flares, rock sliders, a 50-inch LED light bar above the windshield, LED spotlights on the A-pillars, and seven-inch KC Hilites headlights. Rugged Ridge worked over the inside with upgrades like all-terrain floor and cargo liners, plus seat covers, and a new navigation system with a back-up camera. If you want to win it, you can enter the contest at Extreme Terrain once every week until Oct. 23. The winner gets flown to SEMA to have Kevin Tetz hand the keys over. If you just want to see it, you can head to PA for that heritage festival. The Project Trail Force will also lead a Jeep parade that could set a Guinness World Record. The press release below has a lot more info on the build. Good luck.

Chrysler resolves recall issue with NHTSA, will inspect, upgrade affected Jeeps

Chrysler made big news earlier in the month by refusing a recall request from the National Highway Traffic Safety Administration for the 1993-2004 Jeep Grand Cherokee and 2002-2007 Jeep Liberty. Last week, NHTSA boss David Strickland countered by defending his agency's request for the recall of 2.7 million Jeep SUVs. Today marked the deadline for Chrysler to formally respond to NHTSA, and it seems that both parties have met in the middle with Chrysler inspecting and upgrading some of the affected vehicles without using the word "recall," which would constitute the admission of a defect; instead, Chrysler said that it is conducting a "voluntary campaign."
At issue on these vehicles is the positioning of the fuel tank behind the rear axle that could get damaged during a rear-end collision. NHTSA has stated that at least 51 people have been killed in rear-end collisions involving these Jeeps after the vehicles caught fire, to which Chrysler countered by pointing out that both models "met and exceeded" the requirements for fuel-system integrity.
As a compromise on the situation, Chrysler says that it will inspect all pre-2004 Grand Cherokees and pre-2007 Liberty models and, "if necessary, provide an upgrade to the rear structure of the vehicle." According to Automotive News, this upgrade will consist of adding a trailer hitch that will presumably better protect the rear-mounted gas tank. Vehicles already equipped with a factory or Mopar hitch will not be modified. Chrysler's official statement on the matter is posted below, but no additional information has been released, such as when the campaign will begin and how many vehicles could be affected.
