Chrysler’s 3.6 liter Pentastar V6 engine gets a healthy change for 2016 with enough new features and technical goodies, that I thought it was interesting and newsworthy enough to share.
Now, this engine is under the hood of a lot of vehicles from Dodge, Jeep, Chrysler and RAM Trucks.
And to keep progress moving in power gains and better efficiency, Chrysler gave this engine a healthy makeover.
A new valve-train features a two-mode variable-valve lift system. With two modes, it can operate with low lift which is more fuel efficient.
It can also open them more on high lift mode which enables free breathing and more power when needed.
And to that, the maximum compression ratio has been increased to 11.3:1, with those cylinders fed with an all-new intake system that now uses cooled EGR.
This is something new, a feature usually only found in modern diesel engines.
By cooling the recirculated exhaust-gas that gets introduced back into the fresh-air intake, a more aggressive tune can be maintained for maximum power, with less detonation that would be caused by the higher heat.
With these and several other improvements, the new 2016 Pentastar V6 picks up some 15 percent more torque, and a few more horses.
And most importantly, it does this while also offering up better fuel economy.
Now, final specs weren’t yet announced for the new engine, but it will first appear in the 2016 Jeep Grand Cherokee, the roll out across the line of vehicles one by one.
