According to sources that are familiar with the program, the Chrysler Group’s Pentastar family of V6 engines will undergo an upgrade process in the near future – which adds direct injection, turbo charging and other mileage improving technology.
Called the Pentastar Upgrade (PUG), the improvements would enable the use of smaller displacement engines that would deliver increased power and a better fuel autonomy. That means most Chrysler vehicles powered by the V6 range would get power boosts and increased fuel economy – with the possibility of previously naturally aspirated engines to use turbos, while the MultiAir variable valve timing technology from Fiat is here to stay. While Chrysler spokespersons declined any comment on the project, Automotive News reports the sources said the first upgraded 3.6-liter V6 could make its debut on the Jeep Grand Cherokee, as part of a late 2015 refresh.
Next up should be the next-generation of the Chrysler Town & Country minivan, scheduled for arrival in 2016 – with the people who opted to remain anonymous saying the model should come equipped with a refreshed 3.2-liter V6, replacing the current 3.6-liter V6. Just as is the case with some of the variants of the 2015 Jeep Cherokee, the updated 3.2-liter V6 would be available with the new nine-speed automatic transmission. According to the sources, the new powertrain option, coupled with the new and enhanced aerodynamics and the lowered weight should buoy the minivan’s fuel economy. It should come around 25% better than the current EPA ratings of 17 mpg city/25 highway.
