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.

Weekly Recap: Jaguar takes a leap with price cut, new strategy

Jaguar was one of the famous automotive props and plotlines in the now-iconic drama Mad Men. There's a scene where the show's protagonist, Don Draper, deftly undercuts an influential Jaguar dealer by indicating that get-me-in-the-door local radio spots would be an effective way to sell cars like the slinky E-Type. The British executives think this is folly – Draper knows they will – and his advertising strategy wins out over the dealer's approach to move the metal. Jaguar's not doing that, but half a century later in the real world the company is launching plans to make its cars more attainable to new and younger customers like Millenials. These aren't coupons, but this is a leap for Jaguar, which has long banked on sexy styling and its rich motorsports history to overshadow its past mechanical flaws. Put simply, Jaguar is addressing the reasons why people, especially the younger set, don't buy its cars. The 2017 XE will start at $35,895 when it launches next spring – which makes it an attractive buy for a successful, relatively young person. When it's time to move up, the redesigned XF will be more attainable, coming in at $52,895, which is $5,275 less than the 2015 model. The flagship XJ sedan and the enthusiast-oriented F-Type sports car will also get thousands of dollars worth of added standard features, and Jag is actively pitching them as a better value than their competitors. "The Jaguar brand is on the eve of a major transformation that will see it dramatically increase its presence in the United States luxury marketplace with an expanded lineup, pricing focused on the core of the luxury market, and an all-new ownership package with best-in-class coverage," Joe Eberhardt, CEO of Jaguar Land Rover North America, said in a statement. The brand's quality and reliability dings have also lurked in the back of buyers' minds for decades, though that's an outdated notion. Jaguar placed third in J.D. Power's Initial Quality Study in June and was the top-ranked luxury brand in J.D. Power's Customer Service Index in March. Not content, the company is rolling out an enhanced program called Jaguar EliteCare that launches on 2016 models. It offers a five-year, 60,000-mile limited warranty, the longest among its competitors, with free scheduled maintenance during that period. The plan also covers roadside assistance and connectivity features.

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."
