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.

Chrysler teases upcoming outlay of SEMA cars

Fiat Chrysler Automobiles is hauling a multitude of modified models to the annual SEMA show in Las Vegas this November, and the company is releasing the first teasing sketches of many of them.
Unfortunately, FCA isn't giving many solid details on any of the concepts other than saying the vehicles from Chrysler, Jeep, Dodge, Ram and Fiat all benefit from tuning from its Mopar performance brand. The teaser photos include a sinister-looking Chrysler 200S, Fiat 500 Abarth with two-tone paint and a scorpion on the hood, a red and black 500L, seemingly two different takes on the Jeep Renegade, a green Dodge Challenger wearing the T/A badge, an orange and black Dart, a very neon Charger, just the outline of a red and black Viper, a Ram ProMaster in Mopar livery and a Ram pickup called the Outdoorsman.
Take a look through the gallery to see what you think of the sketches for these concepts, and scroll down for the full announcement from FCA.

Fiat-based baby Jeep spotted testing in US and Europe

Details remain scarce, but our spy photographers have managed to capture the upcoming Jeep B-segment crossover for the first time, testing in both the Alps and in the US. Shown here as a cobbled-together Fiat 500L mule, the new Jeep model is expected to arrive for the 2015 model year and act as a replacement for the current Compass and Patriot models.
According to our shooter, the new "baby Jeep" will share a platform with the Fiat 500X, and both models will be built on the same assembly line in Turin, Italy. We can't tell much from these images, but the added length apparent on this 500L mule would seem to dispel the recent speculation that the new entry-level Jeep model would be sized closer to the Ford Fiesta - since the 500L is already considerably larger than the Fiesta. Powertrain options will likely mirror other Fiat/Chrysler collaborative vehicles like the Dodge Dart, but this Jeep will also try to live up to its off-road roots with an optional all-wheel-drive system.
