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.

GM says it will not sell Opel, Fiat still ready to buy

Automotive News reports General Motors has no interest in selling Opel. The statement comes after an Italian newspaper implied Fiat was ready to buy the brand should the alliance between GM and PSA/Peugeot Citroen fail. The publication reported that Fiat CEO Sergio Marchionne is already crafting a proposal to acquire the German brand in the event GM calls it quits, using a strategy similar to the one that saw Fiat win Chrysler.
Fiat has declined to comment on the situation, but GM Vice Chairman Stephen Grisky said in a statement that GM stands behind Opel and that the brand is "a fully integrated part of GM's global footprint."
Grisky also said the GM-PSA alliance is still strong.
