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 recalling over 280k minivans because airbags may deploy on wrong side

Chrysler has issued a recall for some 2013 Town & Country, Dodge Grand Caravan and Ram C/V Tradesman vans built between May 10, 2012 and June 7, 2013. These vehicles may have a software error that would cause the wrong side (opposite side) airbags to deploy in a crash. With this defect, a left-side impact would cause the right-side airbag to deploy, etc.
The recall affects 281,500 vehicles in total: 224k in the US, 49,300 in Canada, 2,900 in Mexico and 5,300 in other locations. Chrysler will notify owners of effected vehicles, and reflash the offending occupant restraint control module to resolve the issue.

Feds sue Fiat Chrysler, accuse it of cheating on diesel emissions

WASHINGTON - The US government has filed a civil lawsuit accusing Fiat Chrysler Automobiles NV of using software to bypass emission controls in diesel vehicles. The Justice Department suit, filed in US district court in Detroit, is a procedural step that may ramp up pressure on Fiat Chrysler. The suit could ultimately help lead to a settlement, as in an earlier probe of rival Volkswagen AG that will cost VW up to $25 billion, but which affected a much larger number of vehicles. VW admitted to intentionally cheating while Fiat Chrysler denies wrongdoing. It did not immediately comment on Tuesday. US-listed Fiat Chrysler shares were down 2.9 percent at $10.44. The suit also names Fiat Chrysler's unit V.M. Motori SpA, which designed the engine in question. Reuters reported last week the Justice Department and EPA have obtained internal emails and other documents written in Italian that look at engine development and emissions issues that raise significant questions. The investigation has scrutinized VM Motori. FCA acquired a 50 percent stake in VM Motori in 2010 and the remainder in October 2013. The lawsuit asserts the Italian-American automaker placed undeclared "defeat devices," or auxiliary emissions controls, in 2014-2016 Fiat Chrysler diesel vehicles that led to "much higher" than allowable levels of nitrogen oxide, or NOx pollution, which is linked to smog formation and respiratory problems. The suit seeks injunctive relief and unspecified civil penalties. EPA said in January the maximum fine is about $4.6 billion. In January, EPA and California accused Fiat Chrysler of illegally using undisclosed software to allow excess diesel emissions in 104,000 U.S. 2014-2016 Jeep Grand Cherokees and Dodge Ram 1500 trucks. Fiat Chrysler said on Friday it plans to update software that it expects will resolve the concerns of U.S. regulators about excess emissions in those vehicles. The January notice was the result of regulators' investigation of rival Volkswagen, which prompted the government to review emissions from all other passenger diesel vehicles. Volkswagen admitted in September 2015 to installing secret software allowing its cars to emit up to 40 times legal pollution levels. In total, VW has agreed to spend up to $25 billion in the United States to address claims from owners, environmental regulators, states and dealers and offered to buy back about 500,000 polluting US vehicles.
