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.

Chrysler recalls 468,700 Jeep Grand Cherokees, Commanders over rollaway risk

Chrysler has issued a recall covering a combined 469,000 units of the 2005-2010 Jeep Grand Cherokee and the 2006-2010 Jeep Commander (inset). Of that number, 295,000 are in the US, roughly 33,000 in Canada and Mexico and the remainder in other markets. It seems an electrical fault in the transfer case can allow the affected SUVs to shift into neutral on their own, while an Associated Press report says that Chrysler had "found cracks in a circuit board that turns the four-wheel-drive system on and off." The issue was discovered when an owner started his car remotely and it rolled away.
Chrysler is expected to begin notifying owners in June 2013, who can then take their cars to dealers. The dealer will reflash the final drive controller free of charge. There's a bulletin from the National Highway Traffic Safety Administration below with more information.

Toledo mayor, Jeep champion Michael Collins dies from heart attack

The city of Toledo is mourning the loss of its mayor and the campaign to keep production of the Jeep Wrangler in the Ohio city has lost a champion after Michael Collins suffered a heart attack behind the wheel recently. Born, raised and educated in Toledo, Collins was a Marine Corps veteran and a city councilor. He was elected mayor in 2013 and assumed office on January 2, 2014, a little over a year ago. He was driving an SUV provided by the city in a snow storm on February 1 of this year when he suffered a heart attack and crashed into a utility pole. He remained in critical condition for days until he was taken off artificial life-support. During his relatively short term in office, Collins became an outspoken and energetic advocate of keeping the Jeep plant in Toledo, where it has been assembled for decades. The next-generation Wrangler is set to switch to aluminum construction, which could lead to moving its production to another location, but Collins (alongside Governor John Kasich and others) had worked hard to convince FCA US to keep it in town. Whether his efforts will prove successful remains to be seen, but our hearts go out to his friends, family and constituents. Michael is survived by his wife Sandy, three daughters and eight grandchildren. He was 70 years old.
