Report: Pentastar Enhancements to Improve Fuel Economy
Update Could Help Ram Recapture Truck Gasoline MPG Crown
The Ram 1500 underwent a comprehensive makeover in 2013 that added class-exclusive eight-speed automatic transmissions across the lineup, which helped give it class-leading gasoline fuel economy. To bolster its economy chops even further, the 3.0L EcoDiesel model was added for 2014, giving it the undisputed edge in overall fullsize truck fuel economy. Ford recently announced EPA figures of 19 city and 26 highway for the 2015 F-150, giving it the top fuel economy rating for a gasoline model in the fullsize segment. However, according to Automotive News (AN), enhancements to Chrysler’s family of Pentastar V-6 engines could help Ram to re-capture the gas truck MPG title.
Nearly 5 years after its introduction, the Pentastar will finally get direct fuel injection and may add some turbocharged variants to the lineup in specific applications. AN reports that the 2016 Jeep Grand Cherokee may be the first model to receive the updated engine, with the new Chrysler Town & Country and Jeep Cherokee also receiving updated V-6s. The powertrain enhancement may improve fuel economy on the Cherokee by as much as 25 percent, the article claims. Among the Detroit Three, the Chrysler Group is most dependent on truck and SUV sales for its profitability, so improvements in economy could have a significant impact on its overall Corporate Average Fuel Economy (CAFE) rating.
