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.

Jeep Renegade gets new duds courtesy of Mopar

In a uncommon move, Jeep has found itself with customized versions of a car we've become quite familiar seeing on auto show floors well before it's actual on-sale date. But that's okay – we're pretty fond of the little Renegade, and we're even more keen to get behind the wheel, something that's scheduled to take place in just a few weeks. The two Renegade models you see here have been blessed with bits and pieces from the Mopar parts catalog. These Jeep Performance Parts and Authentic Accessories will be made available to buyers of the Renegade who want to add some factory-backed custom flair to their rough-and-tumble baby crossovers, whether they plan to stay on the asphalt or head off the beaten path. Starting on the street, the Urban Jeep Renegade doesn't really have any major modifications, its factory-spec bike carrier, mirror caps, grille rings, taillamp surrounds and roof rails in Omaha Orange paint over an Anvil-color base serving more to make it stand out from the crowd than actually offer any additional capability. The interior of the Urban Renegade also gets Omaha Orange highlights to go along with Katzkin leather seats. On the dirtier side of the crossover equation, the Commando Green off-road Mopar-modded Renegade gets concept skid plate, prototype rock rails, rear valance and production roof rails provide some added protection and carrying capabilities. X-shaped graphics mimic the jerry can-style motif of the Renegade's tail lamps. Inside, Commando Green bits again join Katzkin leather.
