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 300 SRT dead in US, updated elsewhere

The Chrysler 300 SRT is officially dead here in the US, but the sedan's big V8 continues to rumble in a handful of other markets around the world. In fact, the model just received a refresh abroad to fit the standard version's recently updated styling. According to Car and Driver, customers in countries like Australia, Japan, South Africa, South Korea, and a few other places can stop by their local Chrysler dealer soon to pick up some of this imported muscle. For the refresh, the 300 SRT's 6.4-liter V8 remains under the hood producing 470 horsepower, and it's now hooked up to an eight-speed automatic gearbox. The styling also gets some updates like LED lights in the lower air dam, a reshaped mesh grille with the SRT logo, and a simplified design for the taillights. If it seems odd to go to the work of updating the 300 SRT's styling, while killing off the model in the US, the reason has to do with FCA's brand strategy here. Dodge is supposed to be the automaker's performance marque in America, and according to Car and Driver, Jeep gets to keep SRT branding on the Grand Cherokee because of the brawny SUV's popularity. That might not last much longer, because reports suggest a Hellcat-powered Trackhawk is on the way. Related Video:

Takata airbag recall claims 209k Chrysler, Dodge vehicles

Chrysler is expanding the scope of its front passenger side Takata airbag inflator recall yet again to include 139,115 additional vehicles for a total of 208,783 units now needing these parts replaced. The latest campaign affects the passenger side inflators of the 2003-2005 Dodge Ram 1500, 2003-2005 Dodge Ram 2500, 2003-2005 Dodge Ram 3500, 2004-2005 Durango; 2005 Dakota pickup; 2005 Dodge Magnum and 2005 Chrysler 300 (pictured above), 300C and SRT8. It's limited to vehicles purchased or ever registered in Alabama, Florida, Georgia, Hawaii, Louisiana, Mississippi, Texas and the territories of American Samoa, Guam, Puerto Rico, Saipan and the US Virgin Islands. The company expects owners to be notified by February 8. The automaker just expanded the replacement campaign last week to include passenger side inflators in 149,150 pickups from the 2003 model year. However, the parts are not the same. Chrysler says this recall is for the PSPI family of components versus SPI for the last one. The company is also not aware of any injuries or accidents in its vehicles from these potentially faulty inflators, and lab testing of 600 of them finds no issues. Despite this, Chrysler is repairing these models at the request of the National Highway Traffic Safety Administration. Scroll down to read the company's full announcement of the initiative. Statement: Air-bag Inflator (Regional Field Action Expansion) December 12, 2014 , Auburn Hills, Mich. - Chrysler Group is expanding an ongoing regional field action with a recall to replace front passenger-side air-bag inflators in an estimated 208,783 older-model vehicles originally purchased or ever registered in seven U.S. states and five territories. The vehicles are equipped with front passenger-side air-bag inflators from a product family code-named "PSPI." Chrysler Group is unaware of any injuries or accidents involving PSPI inflators of the type covered by this campaign, nor has a Chrysler Group investigation identified a defect in these components. Further, laboratory tests on nearly 600 such inflators did not result in any failures. The inflators affected by this campaign differ in design and construction from PSPI inflators used by other auto makers. They also benefited from a more robust manufacturing process. However, at the request of the National Highway Traffic Safety Administration (NHTSA), Chrysler Group is expanding its replacement action beyond its original scope of Florida, Hawaii, Puerto Rico and the U.S.
