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."

Mahindra fights FCA's Jeep infringement claims

The Indian manufacturer Mahindra is fighting tooth and nail to keep building its Roxor off-road vehicle to sell in the United States. In early August, Jeep mother company FCA filed a complaint with the U.S. International Trade Commission to stop Roxor sales in the U.S. FCA claims the Roxor design is an intellectual property infringement on Jeep design, meant to undercut FCA's own Jeep products on the market. Now Mahindra has released a statement to the commission saying that FCA's complaint is without merit. While FCA stated in its claim that the Roxor is "an imported low-quality knock-off kit car," Mahindra points out that the vehicle took several years to develop and is manufactured in Michigan. Mahindra intends the Roxor to be an off-road vehicle only, and says it does not compete with Jeeps. The Roxor isn't road legal, only comes with a diesel engine and reaches a top speed of only 45 mph. However, it has to be said that the uncomplicated Roxor is far closer to the original ethos of WWII-era Jeeps than the Jeeps FCA currently manufactures. Mahindra also states that FCA agreed in 2009 not to bring about infringement claims as long as Mahindra used a grille design that FCA approved — going with a grille design that clearly differs from the classic Jeep trademark grille. The matter might partially muddled by the fact that the grille agreement was made with 2009's Chrysler instead of today's FCA. Looking back several decades, the entire Mahindra Roxor appearance is at its core based on a 1940s license agreement made with Willys, the original Jeep manufacturer. Mahindra's statement addresses FCA as "Fiat," and it should not be forgotten that Fiat itself manufactured a Jeep lookalike, the Campagnola, from 1951 to 1973 — also with a different grille. Fiat Industrial subsidiary Iveco's history page says the 1951 Campagnola was constructed "according to the Willys mould". Mahindra claims that FCA is using the complaint to create negative publicity to damage Mahindra's reputation. The Indian manufacturer reminds us that it is the first automotive OEM to set up a new manufacturing operation in southeast Michigan in over 25 years — in Auburn Hills, not far from FCA's U.S. headquarters.
