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.

Refreshed Jeep Cherokee gets more conservative styling

When the Jeep Cherokee hit the market a few years ago, it created a bit of controversy within the Jeep community. The two biggest issues were the styling and the fact that the former rough-and-tumble Cherokee was now a soft, car-based crossover. While there isn't much that can be done about the latter, it looks like Jeep is planning to address the Cherokee's love-it-or-hate-it looks. These spy shots, in typical fashion, don't reveal as much as we would like. The Cherokee here has a good amount of camouflage covering the front and rear fascias, the two areas that generated controversy. It looks like the headlights have moved up and sit alongside the bumper, not below it. The seven-slot grille remains, but there would likely be fires in Toledo if that disappeared. The rear has been changed as well, and it looks like there is a body-width trim piece similar to that on the Grand Cherokee. When the refreshed Cherokee debuts, the Jeep lineup will be murkier than ever. More conservative styling would make it look like a baby Grand Cherokee, but that's exactly what the all-new Compass looks like. It seems the pair might step on each other's toes, but Jeep must hope it's better than going to another manufacturer. Look for a full reveal this fall.
