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.

FCA recalling 400k Jeep Wranglers, 40k Fiat 500s

The Basics: Fiat Chrysler Automobiles has issued two recall. The first is for 392,464 Jeep Wranglers in the US from the 2007-2010 model years for the steering wheel airbags. The second covers 39,217 examples of the naturally aspirated 2012-2016 Fiat 500 in connection with the clutch release mechanism. The Problem: In the Wranglers' steering wheel, excessive accumulation of dust and dirt from open-air driving off-road could compromise the clockspring in the steering-wheel assembly and prevent the airbag from deploying in the event of a crash. In the case of the Fiats, the clutch travel in a small percentage of vehicles equipped with manual transmissions "may exceed design parameters" and eventually damage components. Injuries/Deaths: No injuries or accidents been reported to result from either issue. The fix: Dealers will install new back covers and column shrouds in the Jeeps and upgrade the clutch release systems in the 500s. If you own one: Expect to hear from the manufacturer to arrange service. In the case of the Fiat recall particularly, FCA "urges customers to heed the instructions on their recall notices." Related Video: Statement: Clockspring May 18, 2016 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 392,464 older-model SUVs in the U.S. to replace their clockspring assemblies and related components. Located in a vehicle's steering wheel, a clockspring forms part of the circuit that helps control airbag function. An investigation by FCA US determined excessive exposure to dust and dirt – consistent with extensive off-road driving or driving with a vehicle's top and/or doors removed – may compromise the clockspring and eventually prevent driver-side airbag deployment in a crash. If this condition is present, the airbag warning-lamp will be illuminated. If such an event occurs, customers are advised to contact their dealers. The Company is unaware any potentially related injuries or accidents. Affected by this campaign are model-year 2007-2010 Jeep Wrangler SUVs. An additional 7,435 model-year 2011-2016 vehicles equipped with right-hand drive for special duty also are affected in the U.S. Vehicles affected outside the U.S. comprise an estimated 35,412 in Canada; 8,529 in Mexico and 62,580 outside the NAFTA region. Customers will be advised when they may schedule service, which includes installation of a new steering-wheel back cover and a steering-column shroud.
