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.

Next Jeep Wrangler to get hybrid option?

This may the year a Jeep hybrid is officially announced. Really. The Chrysler division may finally be making plans for its first gas-electric powertrain to help boost the group's fuel economy, says UK's Auto Express, citing Mike Manley, CEO of FCA's Jeep division. The guinea pig of sorts may be the Wrangler, which moved almost a quarter-million units in the US last year. The Wrangler could get a hybrid drivetrain by the 2017 model year, as Jeep executives look to maintain the model's feel and torque while boosting its fuel economy. The Wrangler gets a pretty paltry 18 miles per gallon combined out of its six-cylinder mill, so the bar's set pretty low. Of course, we've heard this talk before. In late 2013, Chrysler Asia-Pacific product planning manager Steve Bartoli told Australia's Drive that a Jeep hybrid was pretty much inevitable, though not much has been mentioned since. FCA could use all the help it can get in the fuel economy department. The group brought up the rear among automakers when it came to fuel efficiency, the US Environmental Protection Agency (EPA) said in its EPA Trends report released last October. The FCA models combined for a 21.1 miles per gallon average for the 2014 model year, compared to the 24.2 mpg overall industry average. The group's only electric vehicle in the US is the low-volume Fiat 500e, though the company may start selling a plug-in hybrid version of its Chrysler Town & Country by the end of the year.

Refreshed Chrysler 300 SRT won't be sold in NA

It looks like it might be time to bid farewell to the V8 rumble from the Chrysler 300 SRT - at least if you live in North America. The reported change comes as Fiat Chrysler Automobiles reshuffles its ranks with the Dodge brand, re-absorbing SRT and building its muscular reputation with the Challenger and Charger Hellcat models. Meanwhile, Chrysler is taking a more mainstream approach, and that likely means the end of overt high-performance models from the division for now.
According to Automotive News, the 300 SRT will be discontinued in the US for 2015, but it won't be totally dead. Some right-hand drive markets will still get the brawny V8 sedan next year, a distinction that goes a long way toward explaining some spy shots we've seen recently.
The 300 SRT's North American demise probably shouldn't come as a total shock. In FCA's five-year plan, it says that the 300 is destined for a refresh to be unveiled later this year, presumably at the upcoming Los Angeles Auto Show. There's no mention of the SRT model in the document, though, which seems to signal its end.
