Allpar sources told us that 2016 is likely to hold a power boost for the Pentastar V6 engines.
While the MultiAir 2 was reportedly tested on the Pentastar V6, the increased power was apparently not worth the cost over the efficient, cost-effective dual cam phasing system, which will be updated instead.
“The pug” is likely to get direct injection, at long last, coinciding with cleaner American gasoline. Engineers are also likely to make some changes to increase durability and reliability, having years of warranty data to work from, and to push performance in some areas where they may have been more conservative before.
The revised version might not be ready in time for the new minivans, but will probably be in revised Grand Cherokees and Rams (the 2014 Five Year Plan referred to 2017 as a “major update” for Ram 1500). Hundreds are said to be in circulation for endurance testing and final tuning at this point. Chances are that all cars with Pentastar engines will be updated relatively quickly, rather than waiting for refreshes, though with multiple assembly plants, it’s not that hard for Chrysler to make both upgraded and standard versions at once.
The Pentastar started out as a 3.6 liter engine, and has expanded out to 3.2 and 3.0 liter versions, the latter for export to regions where engines are taxed based on displacement. The engine is adapted for each vehicle it’s used in, with the greatest changes reportedly made for the Wrangler (accommodate water crossings and to physically fit) and the Ram. It currently ranges up to 305 horsepower and has made the Ward’s Ten Best Engines (worldwide) list — one of very few engines without direct injection and forced induction to do so.
