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.

2013 Jeep Wrangler Unlimited Rubicon 4X4

Ice skates are spectacular on frozen water, yet they are dreadful everyday footwear. I consider the Jeep Wrangler equally as specialized.
I recently spent a week with a 2013 Jeep Wrangler Unlimited Rubicon 4X4. Introduced for the 2007 model year, the Wrangler Unlimited is a standard JK two-door with 20.6 inches added to its wheelbase and two additional doors bolted to its passenger compartment. While Jeep offers the Unlimited in seven different trim levels, the desirable Rubicon is the most capable when the pavement ends, as it boasts a slew of hardcore off-road tools including front and rear electronic locking differentials and a front sway bar that can be disengaged at the touch of a button for improved articulation. My I-Look-Like-A-Traffic-Cone test model started with a base price of $34,095 (plus $995 destination). Options including a five-speed automatic transmission, Uconnect, tow package and a premium soft top, drove the bottom line up to $38,630.

Chrysler's Jefferson North plant builds 5-millionth SUV [w/video]

Chrysler's Jefferson North Assembly Plant opened in 1992 for production of the first Jeep Grand Cherokee, but in the subsequent years, the Detroit plant has gone on to produce some of the company's biggest SUVs including the Jeep Commander and Dodge Durango. Earlier this week, the plant produced its five-millionth SUV, which, fittingly, was a Grand Cherokee.
Celebrating the plant's five-millionth unit, the silver 2014 Grand Cherokee was promptly donated to the USO. In addition to this milestone SUV, Chrysler also had a near-perfect 1993-95 ZJ Grand Cherokee on hand for the photo op. Scroll down for the Chrysler press release as well as a video showing some of the speeches from the celebration.
