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 recalling hundreds of thousands of Jeep Grand Cherokee and Commander SUVs

The public might associated ignition switch recalls with General Motors - and with good cause - but that's not the only automaker calling its vehicles back in to fix that sort of issue.
Last month we reported that the National Highway Traffic Safety Administration was investigating an array of Chrysler Group vehicles for electrical-related safety issues. The administration and Chrysler subsequently issued a recall for 700,000 Dodge Journey crossovers, Dodge Grand Caravan minivans and Chrysler Town & Country minivans. But while the Jeeps that were also under investigation were not covered in that recall, they are being addressed in a separate one now.
Although Chrysler reports that it is only aware of a single accident stemming from this issue, it is "committing now to conduct a recall out of an abundance of caution." The recall affects the 2006-2007 Jeep Commander and 2005-2007 Jeep Grand Cherokee, of which it reports there are 792,300 on the road: 649,900 in the United States, 28,800 in Canada, 12,800 in Mexico and a further 100,800 outside of North America.

Sunday Drive: A tale of old favorites and upcoming challengers

Sedans and crossovers dominated the attention of our readers last week, led by the completely redesigned 2018 Honda Accord. It's the Japanese automaker's flagship, and people are seriously interested in finding out how good the latest Accord is. So interested, in fact, that no other single story came close to the brand-new Accord in Autoblog reader interest. Moving down the list we find the equally new 2018 Buick Enclave. The three-row crossover has a lot to offer a family, especially one looking for a nice, quiet ride. If you're looking for the exact opposite of nice and quiet, but still want enough room for you and your significant others, the Subaru WRX that we tested last week may be the perfect ride for you. Or, if you just want to drive fast and aren't at all worried about space, there's the Camaro SS. See? We offer something for everybody. From there, we look to the future. Who isn't interested in seeing the first fully electric vehicle from Porsche? And who isn't intrigued to see the Mission E testing alongside a gaggle of Teslas? A brand-new Jeep is always a big deal, especially when it's the revival of a classic nameplate like the Grand Wagoneer. And finally, we have something completely different: the Rezvani Tank. As always, tune in to Autoblog next week for a front-row seat to all the happenings worth following in the automotive industry. 2018 Honda Accord First Drive | Feels like home again 2018 Buick Enclave First Drive Review | Fortress of quietude 2018 Subaru WRX Drivers' Notes | Turbo traditionalist 2018 Chevy Camaro SS Drivers' Notes | Demonstrative power, middling interior Porsche Mission E caught testing against Teslas Jeep three-row SUV caught on public roads — Grand Wagoneer, perhaps?
