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.

Stellantis reveals STLA Large platform with EV and ICE support

Hot on the heels of a Jeep Wagoneer S teaser and photos of the prototype next-generation Dodge Charger (or Challenger), comes a reveal and details of what will likely underpin both of them: the STLA Large platform. It's one of multiple Stellantis flexible architectures that will be the basis of its upcoming electric cars, and apparently internal combustion ones, too. Stellantis says the STLA Large platform will be for D- and E-segment cars, crossovers and SUVs. In other words, it will be for midsize and large vehicles. For reference, lengths supported will be from 187.6 to 201.8 inches, and width will range from 74.7 to 79.9 inches. It will be highly flexible, too, with Stellantis claiming significant amounts of adjustability in overhangs, wheelbase, suspension placement and powertrain arrangement. The powertrain flexibility is quite impressive. Front-, rear- and all-wheel-drive layouts will be supported. Single- and dual-motor layouts will be on offer. Internal combustion will be available, too, either on its own or as a hybrid. Apparently engines can be fitted either longitudinally or transversely, too. Battery packs with between 85 and 118 kWh of capacity will be offered, with Stellantis claiming that sedan-style vehicles could have a range of up to 500 miles. The packs will also be available in 400- and 800-volt designs. Stellantis noted also that the platform can "easily accept future energy storage technologies when they reach production readiness." This seems to hint that the company is looking at different battery chemistries and maybe even solid-state batteries that could be added more easily in the future. Furthermore, the platform is designed to handle impressive output. Stellantis says that some models on the platform will have 0-to-62 mph times in the 2-second range. Limited-slip differentials for improved power delivery and wheel-end disconnects for reduced mechanical drag are also on the table for this platform. All of these details fit well with the information previously given for the concept Dodge Charger Daytona Banshee and Jeep Wagoneer S. The former was previewed with both battery voltage architectures and a wide range of electric powertrains with between 456 and 670 horsepower depending on specification and upgrades. And that's just for the 400-volt system; the 800-volt option wasn't detailed. We've also seen photos of the Charger chassis seemingly with provisions for gas engines, likely versions of the Hurricane I6.

FCA plotting larger Jeep Renegade, Fiat 500XL

The joint development of the new Jeep Renegade and Fiat 500X goes to show what the combined efforts of the Fiat Chrysler Automobiles group can yield. But don't expect the Italian-American automaker to stop there. According to Autocar, the company is planning to base another pair of larger SUVs on the same platform. The Jeep version would take the place of the previous Compass and Patriot, slotting in between the Renegade and Cherokee. Meanwhile, the Fiat version would further bolster the Cinquecento lineup to sit alongside the 500 hatchback, 500L minivan and 500X crossover. Details remain few and far between at the moment, but they wouldn't be the extent of the growth plans for either brand. Jeep is reportedly zeroing in on a decision on the long-rumored sub-Renegade model, while also preparing to expand up-market with the return of the Grand Wagoneer. Fiat is reportedly abandoning the prospect of offering a full model line as it once did. While the 500 range will continue to form a vital part of the brand's business, it's also tipped to be going after the no-frills, bare-bones market dominated by Renault's Dacia brand. To that end, it would seek to build upon the Panda by offering a larger, but still low-cost hatchback to rival the Ford Focus and VW Golf, and succeed the discontinued Fiat Bravo, but based on the 500L's platform and built in Turkey to keep costs down. This second pillar of the Fiat brand wouldn't likely be offered in the US, however, where we'd expect the 500 line to continue representing the Italian automaker. Related Video:
