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.

Airbag fault on 1M recalled Jeeps getting second look from NHTSA [UPDATE]

UPDATE: Here is the statement we received from Chrysler regarding NHTSA's query: "Chrysler Group LLC advised the National Highway Traffic Administration of the six reports and, in accordance with the Company's long-standing practice, is cooperating fully with the resulting investigation. Customer safety is paramount at Chrysler Group. Customers who are concerned may call 1-800-853-1403."
It appears that Jeep's repairs for nearly one million Grand Cherokees from 2002-2004 and Liberty models from 2002-2003 might not be over yet. The vehicles were first recalled in November 2012 because the front airbags could suddenly deploy without being in an accident. Now, the National Highway Traffic Safety Administration is opening a recall query into them because of reports of inadvertent activation on some already corrected vehicles.
The original problem affected over 919,000 vehicles worldwide, including 744,822 in the US, and was caused by a degrading circuit in the wires that control the airbags. In some cases the airbag warning light would come on just before the premature activation, but in other cases it would just happen. The automaker installed an "in-line jumper harness with an integrated electrical filter" meant to eliminate the power spikes believed to be the cause.

Jeep hiring 1,000 part-time workers in Toledo on Wrangler, Cherokee demand

The new Jeep Cherokee has been quite a success for Chrysler, but its factory workers are getting tired. The automaker has agreed to hire up to 1,000 part-time, temporary employees at its Toledo Assembly Complex where the CUV and Wrangler are built. It will allow the company to keep Jeep production moving, while giving laborers a break.
According to plant manager Chuck Padden in the Toledo Blade, full-time workers are regularly taking on 60 hours a week, and it's beginning to wear on them. "To get them more time off is important to us, to make sure they're refreshed, and can work safely," said Padden.
Chrysler has already hired 380 temporary, part-time workers for the plant, and 50 have been converted to full-time employees. The company is in the process of interviewing the rest of the new hires now and plans to have all 1,000 in place by the summer. They will work between 10 and 30 hours a week mostly on weekends for $15.78 per hour with limited benefits. The temporary positions will last "as long as demand continues for the Jeep Wrangler and the Jeep Cherokee," said Jodi Tinson, Chrysler spokesperson for manufacturing and labor communications, to Autoblog in an email.
