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 3.0L EcoDiesel V6: Autoblog Technology of the Year finalist

Offering a diesel engine in an American pickup is anything but new - Ford, General Motors and Chrysler all offer excellent and almost impossibly powerful oil-burning engines in their various fullsize trucks. What is new and novel about the 3.0L EcoDiesel, though, is its size, and the variety of vehicles that use it. It's the smallest engine, as far as displacement is concerned, currently offered in a large truck in the US, and, for 2014 and 2015, it is available in the Ram 1500 and the Jeep Grand Cherokee.
Though it may be small, it's got muscle. While 240 horsepower isn't particularly impressive these days, the engine's 420 pound-feet of torque more than makes up for that. The torque rating is even greater force than even the big 5.7-liter Hemi can muster. Chrysler's well-regarded eight-speed automatic transmission makes the most of all that bull-headed pulling power in both the Ram and Grand Cherokee. Chrysler claims the Ram EcoDiesel 1500 can tow as much as 9,200 pounds when properly equipped, which makes it "90-percent of the Hemi with a night and day difference in fuel economy."
Make no mistake; it's that promise of a sizable fuel economy improvement that many long-haul truckers will be most interested in. In the Ram 1500 that we tested for our Tech of the Year competition, the diesel engine costs $2,850 more than the gas-fed V8, and Ram estimates that EcoDiesel buyers will pay off their investment when compared to the Hemi engine in less than three years, which is considerably less time than the 4.5 or so years the average buyer will keep his or her fullsize pickup. The more you drive, the more you'll save, and the math proves equally as effective in the Jeep Grand Cherokee.

Jeep owner inadvertently receives 2018 Wrangler hood from scrapyard

After an apparent mix-up, FCA may be looking for a new scrapyard to which to send prototype parts. JLWranglerForums.com member Redrockjk recently purchased a used Wrangler hood from a yard near the FCA proving grounds. When he ordered it, he thought it was from a 2014 model, and while it looked very similar to his current hood, after installing he discovered something unusual. It was too long. From what we can see in the photos from JLWranglerForums.com, the leading edge of the hood sticks out roughly two inches from the top of the Wrangler's grille. The greater length is also clear when the hood is placed next to its likely predecessor. The receivers for the exposed latches are also too far forward to be used on a current Wrangler. Redrockjk also said there wasn't a VIN or a part number anywhere on the hood. As if those details weren't a big enough red flag, Redrockjk reported that the used parts supplier contacted him to ask for the hood back. We reached out to Jeep to see if they could confirm if this is a hood for the next-generation Wrangler. Unsurprisingly, the company had no comment at this time. Considering the details, and the proximity of the scrapyard to an FCA proving ground, there's a better than zero chance this is from a pre-production 2018 Wrangler sent to the yard to be scrapped. No word on whether the hood was aluminum, as has been rumored. Except for the length, the part fits pretty well on the current model. The hood vents present are also similar to those found on some current models. It's one more piece of evidence that the next Wrangler won't stray far from a proven formula.
