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.

‘Star Trek’ actor's family settles with Fiat Chrysler over his death

LOS ANGELES — The family of late "Star Trek" actor Anton Yelchin has settled a wrongful death lawsuit with Fiat Chrysler Automobiles NV over the rollaway crash of a Jeep Grand Cherokee that killed the up-and-coming actor almost two years ago. Terms of the settlement, which was filed in Los Angeles Superior Court on Tuesday, were not disclosed. The lawsuit filed by Yelchin's parents, celebrated Russian figure skaters Victor and Irina Yelchin, is believed to be the first wrongful death complaint filed over Fiat Chrysler's April 2016 recall of more than 1.1 million vehicles due to a rollaway risk. Yelchin, 27, best known for playing navigator Pavel Chekov in the "Star Trek" movie reboot, died in June 2016 when his 2015 Grand Cherokee rolled backward in the steep driveway of his Los Angeles home, pinning the actor against a brick wall and fence. Yelchin's final role was in the indie film "Thoroughbreds," which was released this month. In a statement, Fiat Chrysler said on Thursday the company is "pleased that we've reached an amicable resolution in this matter. ... We continue to extend our deepest sympathies to the Yelchin family for their tragic loss." Messages left with Yelchin family attorney Gary Dordick seeking comment were not immediately returned. The lawsuit also accused Fiat Chrysler of negligence, product liability and breach of warranty. Dordick said when he filed the lawsuit that Fiat Chrysler had mailed a recall letter to Yelchin that was received seven days after his death. Final recall notices were sent during that time, but interim notices had been mailed at least 17 days before Yelchin's accident, Fiat Chrysler said. At the time of Yelchin's death, the rollaway problem had been tied to at least 68 injuries, 266 crashes and 308 reports of property damage. Drivers complained they would exit vehicles with the engine running falsely believing the vehicle was in park. Fiat Chrysler furnished a software upgrade to the affected 2014-2015 model year Jeep Grand Cherokee sport utility vehicle as well as 2012-2014 Dodge Charger and Chrysler 300 sedans.Reporting by Eric KelseyRelated Video:

The Jeep Grand Cherokee Trackhawk is pretty much good to go

We've been stalking the Jeep Grand Cherokee Trackhawk for months, and now we're getting our best look yet at the devilishly powerful sport utility vehicle. From a distance, the JGC looks almost stately in black. Look closer and you see the SRT badges and the big brakes. Look past the wrappings and you see large air intakes in the lower fascia. All of this reinforces the Trackhawk's performance pedigree, which will be anchored with the 6.2-liter supercharged Hemi Hellcat V8. It's rated at 707 horsepower in the Charger and Challenger Hellcats. The Jeep will use four-wheel drive. These up-close images show off the Trackhawk's simple design. Like the Dodge Hellcats, Jeep appears to be letting the power and capability stand on their own. Previously, we've only seen the Trackhawk from a distance or in blurry video. The Trackhawk's arrival comes as Fiat Chrysler expands Jeep's global presence. The company is increasingly looking to its venerable off-road brand for sales volume, image building, and profits as it re-aligns its car business and looks for potential partners. The Trackhawk looks nearly production ready, and we expect it to go on sale in 2017. Also, don't confuse it with the Trailhawk, which is a trim level you can buy on the 2017 Grand Cherokee.
