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.

NHTSA closes probes on Jeep Grand Cherokee, Ford Freestar and Mercury Monterey

The Detroit News reports the National Highway Traffic Safety Administration has officially closed its investigations into 2012 Jeep Grand Cherokee, 2004-2005 Ford Freestar and Mercury Monterey models. The separate probes found no issues that pose safety concerns. NHTSA began investigating certain Grand Cherokee SUVs over complaints that power steering hoses could detach during operation, thereby increasing the risk of a vehicle fire. Of the 24 reports of failure, none alleged smoke or fire in the engine bay, and Chrysler has since modified the power steering cooler assembly to reduce the likelihood of the failure.
Meanwhile, certain Ford Freestar and Mercury Monterey vehicles garnered a government probe after receiving complaints that the models were equipped with faulty scissor jacks. The agency had received six reports of the jacks failing or causing injuries, including one incident that resulted in a fatality. But NHTSA says the jack failure rate is similar to those found in other vehicles. In those six cases, the government agency found the jacks were being used for something other than changing a tire, and investigators could not determine whether the emergency brake was set or the rear tires were properly chocked.

Fiat Chrysler and Peugeot boards meet to finalize merger

MILAN/PARIS — The boards of Fiat Chrysler Automobiles and Peugeot will meet separately on Tuesday to discuss finalizing an initial agreement for a $50 billion merger to create the world's number four carmaker, sources said. A source close to FCA said the two companies could announce the signing of a binding memorandum early on Wednesday, followed by a conference call to explain further details later in the day. The two mid-sized carmakers announced plans six weeks ago for a tie-up to help them deal with big challenges in the industry, including a global demand downturn and the need to develop costly cleaner cars to meet looming anti-pollution rules. Ahead of the meetings, entities representing the Peugeot family, Etablissements Peugeot Freres (EPF) and FFP, unanimously approved a proposed memorandum of understanding for the planned merger, a source familiar with the situation said. FCA and PSA have said they would seek to finalize a deal by year-end to create a group with 8.7 million in annual vehicle sales. That would put it fourth globally behind Volkswagen, Toyota and the Renault-Nissan alliance. PSA's Carlos Tavares will be chief executive and FCA's John Elkann — the scion of Italy's Agnelli family, which controls FCA through their holding company Exor — chairman of the combined company. The group will include the Fiat, Jeep, Dodge, Ram, Chrysler, Alfa Romeo, Maserati, Peugeot, DS, Opel and Vauxhall brands, allowing it to serve mass and premium passenger car markets as well as those for trucks and light commercial vehicles.
