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 refresh spied with big infotainment screen

Based on these recent spy shots, it looks like the littlest Jeep is getting a little makeover soon. They show a Renegade with camouflage on the front and rear, indicating there will be some changes to the outside. Whatever those changes are, they're extremely subtle. The headlights and taillights look untouched. The grille may have slightly wider slots than the current one, and the available fog lights look a little bigger. The biggest change appears to be inside. Sitting in the center stack is a massive touchscreen. It's bigger than any available on the current Renegade. It also pushes physical buttons and knobs for controls lower down in the stack, instead of surrounding the screen. The lower part of the center stack has also been redesigned for this new button layout, which includes driver assist buttons, stereo controls and climate controls. Fans of manual transmissions will also be happy to see this newer Renegade features a stick-shift. Part of that could be because this Renegade is probably a European model, based on where the images were taken. But seeing as this is a light refresh, and Jeep already offers a manual here, it should still be available on U.S. models, too. Also, considering how mild this update is, we would expect to see it revealed by the end of this year. Related Video:
