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.

100,000 Jeep Cherokee models subject to further 9-speed recalibration

It seems that the software problems with the nine-speed automatic gearbox in the Jeep Cherokee continue to mount. The programming already caused multiple development delays and even postponed the Cherokee's market launch by roughly two months. Now, Jeep has issued another recalibration to hopefully assuage unhappy drivers.
According to Automotive News, this reflash for the allegedly jerky transmission covers over 100,000 Cherokees built before May 5, but it's not technically a recall. If owners are having problems and complain to the dealer, they get the new software. Otherwise, they continue with the current version. New vehicles on dealer lots also receive the latest revision to the programming. It takes only around five minutes to install, but technicians need to take the Cherokee on a test drive to adapt the gearbox to the changes.
The Cherokee's transmission software has been problematic practically since the beginning. The Jeep plant in Toledo, OH, briefly idled its second-shift workers last year to take care of the issue. Since the launch issues for the crossover, demand has been strong. Jeep added another 1,000 temporary workers to the Toledo factory to keep up, and sales were on par with the Wrangler in just its first two months.

2016 Jeep Wrangler Backcountry is Xtremely Purple

Assuming you're headed into so-called backcountry to do fun, outdoorsy kinds of things, chances are, you wouldn't want to use a bright purple vehicle with hot pink graphics as your means to get off the beaten path. Particularly if you're doing those outdoor activities in a winter wonderland, surrounded by nature's own cold, white blanket. Fortunately, then, Jeep is offering its new Wrangler Backcountry in four colors that aren't called Xtreme Purple: blue, black, white, and gray. No matter which hue you choose, though, you'll get the graphics package, so best to bear that in mind. Besides its searing shade of paint, the Wrangler Backcountry is based on the Sahara model and comes equipped as you'd expect for a real, useful, backwoods vehicle. An off-road-spec front bumper joins a matching powdercoated rear bumper, and its 17-inch wheels are borrowed from the hardcore Rubicon model. Buyers will have a choice of Rubicon Rock Rails or Sahara side steps to ease ingress and egress, and a hardtop in either black or, for an added price, a body-color. But hopefully not purple. The interior is updated for the Wrangler Backcountry with black and grey plastics and stitching, along with black leather and "sport mesh" seating surfaces. A nine-speaker Alpine sound system pumps up the jams, and Bluetooth comes standard.

Oh, and if you do really like Xtreme Purple, you should know that the Wrangler Backcountry is the only Jeep you can get in this particular retina-assaulting hue. 2016 Jeep Wrangler Backcountry The Jeep Wrangler Backcountry boasts a winter capability theme and is based on the Wrangler Sahara model. It features a Backcountry decal on the front fender and rear quarter panel, a unique off-road front and rear powder coated bumper, 17-inch Rubicon wheels painted in Mid-gloss Black and a black fuel fill door. Wrangler Rubicon rock rails are standard on the Wrangler Backcountry, but Sahara side steps are also available at no additional charge. A black hard top is standard, but an optional body color hard top is also available. Wrangler Backcountry is available in five colors: Hydro Blue, Black, Bright White, Granite Crystal and Xtreme Purple. Backcountry is the only model in Wrangler's lineup available in Xtreme Purple.
