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 Cherokee faces on-sale delay

A report in The Wall Street Journal looks at some of the obstacles to the 2014 Jeep Cherokee that go beyond its mootable yet "very contemporary" looks, almost all of them based on Fiat's financial position. Starting with that sheetmetal, in defense of it SRT president Ralph Gilles and Jeep design head Mark Allen said they wanted to "make sure the design still looks modern five years from now."
The WSJ piece doesn't cite longevity as a factor, instead saying that its features originated in a design for an Alfa Romeo, the transformation into a Jeep design meant allowing Chrysler get it to market more quickly and save "hundreds of millions of dollars" in engineering.
The need for Fiat to save money while it weathers the European situation has cut budgets for development, engineering and the pace of retooling the Toledo, Ohio plant to build the Cherokee. In a familiar case of snowballing at work, among the effects will be pushing back the Cherokee's volume sales date and delaying updates to some of Chrysler's other products.

Dodge Viper production to end after 2017

We can't say we're surprised, but we're still saddened to report that the Dodge Viper will not live on past the 2017 model year. It's had a solid 25-year run, though, and that's worth celebrating. Fiat Chrysler Automobiles does just that for the Viper's final model year, with five special editions (some of which seem less special than others, admittedly): The 1:28 Edition ACR, GTS-R Commemorative Edition ACR, VoooDoo II Edition ACR, Snakeskin Edition GTC, and Dodge Dealer Edition ACR. Instead of running through what makes each of these 2017 Vipers special, we'll direct your attention to the press release below and the images above. All but the Dodge Dealer Edition commemorate memorable Viper models of the past 25 years, and the GTS-R is probably the pick of the litter with its classic blue-on-white paint scheme. Unless you prefer to err on the side of gaudy, in which case Dodge has you (and your car) covered with Snakeskin Green. If none of these special-edition Viper models strikes your fancy but you'd still like to park a 2017 Viper in your garage, fret not. Dodge is still offering its "1 of 1" customization program for the Viper's final year of production. Finally, instead of dwelling on the past, even when that past is as exciting as the Viper's, let's choose to look to the future with the only logical question left unanswered: What's next?
