Automotive News is reporting that Chrysler will add direct injection and turbocharging to some variants, potentially enabling the company to use smaller displacement versions of the engine in a larger proportion of its range.
The project, entitled Pentastar Upgrade or PUG, will debut underneath the bonnet of the refreshed Jeep Grand Cherokee, which debuts towards the tail-end of 2015.
The next major release to receive the updated V6 engine will be the replacement for the Chrysler Voyager. Known as the Chrysler Town and Country and Dodge Grand Caravan in North America, Chrysler's big-selling MPV will replaced by a single "sexy" new model.
Unidentified sources who spoke to the industry publication indicated that the new people mover will feature a 3.2-litre V6 in place of the 3.6-litre V6 currently employed in its homeland. Paired with a nine-speed automatic transmission, improved aerodynamics and reduced weight, the next-generation Voyager is claimed to be 25 per cent more fuel efficient than the current 3.6-litre V6-equipped model.
The Pentastar V6 made its debut in 2011, and is currently available in 3.0-, 3.2- and 3.6-litre versions. In Australia the 3.2-litre six-pot is employed in the new Jeep Cherokee, while the 3.6-litre variant does service in the Chrysler 300, Dodge Journey and Jeep Grand Cherokee.
