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 Wrangler Red Rock concept brings Moab to SEMA

Among the concepts that FCA is showcasing at SEMA this year, the Jeep Wrangler Red Rock concept has been decked out with accessories from both the Mopar and Jeep catalogs. The concept is based on the existing Wrangler Unlimited Rubicon Hard Rock edition, but has been taken even further in for this show truck. It pays tribute to the Red Rock 4-Wheelers club and the Easter Jeep Safari it hosts every year in Moab, UT. The Red Rock concept rides on a 2-inch lift kit with 17-inch beadlock wheels shod with 35-inch all-terrain tires. It also has differential covers, a reinforced swing gate and wheel mount, a power winch, LED headlamps and fog lights, and an onboard CB radio. To help it crawl those rocks, it boasts electronic locking differentials, a Rock-Trac transfer case, and Dana 44 solid axles front and rear. Visually setting this concept apart are such special touches as a power-dome hood, red tow hooks front and rear, new rock rails, a color-keyed grille with low-gloss inserts, low-gloss bumpers, and of course the requisite special badging. Inside it's been done up in brown leather with silver accents and a special grab-handle plaque. This particular version will remain a showpiece only. So if you want to see it, you'll have to head to the show floor in Vegas this week. However Jeep is committed to undertaking a production run of 50 examples with many of the same special touches to celebrate the 50th anniversary of the Easter Jeep Safari next year.

FCA inline-six rumored to be real, headed for Jeep Wagoneer

In September, Allpar reported that that clues being dropped at Fiat- Chrysler headquarters, in the carmaker's factories, and on engineer resumes pointed to the development of an inline six-cylinder engine. The site has just proclaimed the rumor is reality, writing that the straight-six, "turbocharged to meet or beat 5.7 Hemi power ratings, with a smoother torque curve, is on the way." The motor's first outing is expected to be either the next-generation Jeep Grand Cherokee, debuting perhaps next year, or the Jeep Wagoneer, debuting in 2020 or 2021. "Tornado" is the purported codename for the power plant said to be just under three liters in displacement, expanding the family begun with the Global Medium Engine 2.0-liter turbo codenamed Hurricane. Engine bay constraints and a long use horizon mean engineers won't simply add two more cylinders to the GME, however. Allpar says the brief is to keep the Tornado GME-T6 — the alphanumeric for "turbocharged six" — no more than three inches longer than the Tigershark 2.4-liter four-cylinder. That means "major design changes" that could include a space-saving head, more closely spaced cylinders, and no cylinder liners. An FCA division called Comau could be called on for its "SmartSpray" plasma lining technology. Allpar muses that the standard version of the engine for Chrysler, Dodge, Jeep, and Ram could get a single twin-scroll turbocharger. Performance trims for Alfa Romeo and Maserati could get different heads and maybe twin turbos, an SRT version might also get both those tweaks. History shows that the Italian versions would make changes to the block, as well. Even so, the Tornado would be less expensive than any Ferrari-supplied V6. A straight-six would put FCA in company with current adopters BMW and Mercedes-Benz, future users like Jaguar, and perhaps Aston Martin. The engine would span the widest range of use cases in the U.S. carmaker's portfolio, though. Potential applications include being a base engine for Ram trucks, serving double duty as a base engine and 5.7-liter Hemi replacement for the Dodge Charger and Challenger, working in the high-end Jeeps, and as a properly hot trim — with Ferrari-designed heads — in the luxury Italian sports cars. The Alfa Romeo Giulia begs for just such motivation to fill the gap between the 280-hp, $42,695 Ti Sport RWD and the 505-hp, $73,700 Giulia Quadrifoglio RWD. And a twin-turbo inline-six in a Maserati Alfieri would stack up nicely with the Germans.
