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 still working to improve Cherokee's 9-speed auto

Fiat Chrysler is hoping an upcoming software update will stem the tide of consumer complaints surrounding its nine-speed automatic transmission. Owners of the 2014 Jeep Cherokee have reported a number of problems on the National Highway Traffic Safety Administration's SaferCar.gov website, since the new model and its troubled gearbox arrived way back in October 2013. The software update is "intended to keep the vehicle performing as intended, and to prevent durability issues from occurring in the future," an FCA spokesperson told Automotive News, and will be available to owners of both the 2014 to 2015 Jeep Cherokee and the 2015 Chrysler 200, which also uses the 9AT. While FCA will be notifying consumers of the update, owners can also request the software reflash if they happen into their dealer before then. Despite the widely documented problems with the transmission, the only complaints on NHTSA's website relate to the 2014 Cherokee – neither the 2015 Jeep nor the 200 have received any complaints. That bodes well as FCA prepares to begin deliveries of the 2015 Jeep Renegade and launch the Fiat 500X, both of which pair the 9AT with the 2.4-liter Tigershark four-cylinder. "We have had to do an inordinate amount of intervention on that transmission, surely beyond what any of us had forecast," FCA CEO Sergio Marchionne told Automotive News. "There are things that we have done – that we continue to do. Our proactive customer care intervention has actually increased in intensity on these vehicles in 2014, especially in the second half." What's fascinating about the 9AT's problems are that they haven't been the fault of manufacturer ZF, but have related to software that wasn't "mature" and had "teething problems," Marchionne has said previously, AN reports. With the lack of criticism for the 9AT in 2015 models and this pending software update, though, here's hoping that FCA has finally figured out its fuel-sipping gearbox. Related Video:

Jeep Wagoneer, Grand Wagoneer, and pickup confirmed for production, all built in the US

Jeep has confirmed some much-anticipated future models: a new Wagoneer and Grand Wagoneer as well as a pickup truck, which we expect to be based on the Wrangler. FCA has also announced where these new vehicles be produced, the investment involved, and that adding the models will create 2,000 American jobs. The Wagoneers will be built at FCA's Warren Truck Assembly Plant in Michigan, which currently produces the Ram 1500. The overhaul required to add the Jeeps will also set the plant up to build Ram Heavy Duty models, which are currently made in Mexico. (It's not clear whether this would be additional Heavy Duty capacity or a complete move of production of those trucks to the US.) The confirmed Jeep pickup will be built at the Toledo Assembly Complex in Ohio as expected. This is the same plant that builds Wranglers today and will produce the new JL Wrangler that the pickup version is expected to use. View 30 Photos All of these factory upgrades are part of a $1 billion investment by FCA. The retooling is scheduled to be completed by 2020, which means these models are likely to come online for the 2021 model year, which jibes with the rumors that the Wagoneers have been delayed. That the large Jeeps will be built at the plant that currently produces Ram 1500s also leads us to believe that they will in fact use a version of the Ram truck platform instead of being built off the Grand Cherokee platform as originally planned. The timing of this announcement and its mention of Mexico and US jobs may have something to do with recent talk from President-elect Trump about US auto industry jobs and possible tariffs to be imposed on vehicles built across the border. Marchionne says these plans have been in discussion "for some time" but it's not clear what that timeframe was. Trump has targeted Ford, General Motors, and Toyota in recent tweets but has stayed quiet on FCA. While the announcement may have been political in nature, Jeep fans will no doubt welcome the news of the returning nameplates and the long-awaited pickup model.
