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.

What's really going on with the 2014 Jeep Cherokee's transmission issues?

On September 23, Automotive News reported that Chrysler had idled the second shift workers it hired just five weeks prior at its Toledo Assembly Complex to build the 2014 Jeep Cherokee. At the time, Chrysler said it had "built the critical number of vehicles we need to stock dealerships once containment is released" and did not want "to put additional strain on our logistics partners ... upon release." That reasoning was not only unusual, it didn't seem to make sense.
It appears the center of the nine-speed issue is software, not hardware.
That same day, the Detroit News ran a piece claiming workers at the Toledo factory said the halt was due to issues with the Cherokee's transmission. It put the number of already-built Cherokees needing fixes at 1,000 and said that some of the workers not laid off had been instructed "to take the Jeep on long test-drives." That made more sense. Three days later, on September 26, Automotive News reported that the 500 workers laid off had been reinstated, with engineers "speeding repairs on the SUV's powertrain software." The AN piece didn't put a number on how many units are being fixed, but it did say that 12,000 have been built and are awaiting delivery to dealers. The best it could say about when dealers will get them, however, is that "progress on a fix is being made. It's unclear when shipments to dealers will start."

Toledo continues fight for Jeep Wrangler production, despite mayor's death

Where will the next-generation Jeep Wrangler be built? That's an open question, but it's one that the city of Toledo, OH desperately wants to be the answer to. The city suffered a major blow, though, with the death of Mayor Michael Collins earlier this month. Collins had been the city's biggest champion during talks with Fiat Chrysler Automobiles, before suffering a fatal heart attack on Feb. 6. But Collins' tragic death isn't dampening the city's desire to carry on as the home of the Wrangler. "The mayor's passing is tragic. But on Monday, when I came to work, I knew exactly what I needed to do and exactly what needed to be done," the city's director of development, Matt Sapara, told the Detroit Free Press. According to the Freep, Sapara said Toledo and the state of Ohio have delivered an outline of a development plan that would give FCA the ability to buy an extra 100 acres to expand the factory. This is to help accommodate FCA's targeted output of 300,000 to 350,000 next-generation Wranglers, up from the 240,000 the factory can make now. "Our target in the proposal is to provide a way to increase the production capacity to a number that allows Fiat Chrysler to meet its business model," Sapara told the Freep, adding that the land could be available later this summer. FCA, meanwhile, has shown a somewhat ambivalent attitude towards Toledo production, with CEO Sergio Marchionne openly discussing the pros and cons of continuing to build the Wrangler south of the Michigan border. "We are going to take a very hard look at this without ignoring what these guys have done," Marchionne told the Free Press at last month's Detroit Auto Show, adding that he'd like to keep production there, provided the cost of retooling is comparable to relocating to another facility.
