With stricter CAFE standards just around the corner, Chrysler is looking at giving their Pentastar V6 range some big changes.

Automotive News has learned from sources about a new plan called Pentastar Upgrade - or PUG. PUG will feature such improvements as direct injection, turbocharging, and other technologies to bring more power and better fuel economy. Fiat's MultiAir variable valve timing technology will remain.

Now the first of these updated engines could arrive in the 2015 Grand Cherokee in the guise of a 3.6L V6. This will be followed by a updated 3.2L V6 in the 2016 Town & Country minivan.

The pentastar today is very efficient. Direct injection will make it more so.

With turbos, we're probably looking at a base Hemi replacement.

Yet DI on Pushrod engines from GM seem to do the same thing compared to turbo. I wonder if this marketing push is really just that, no real benefit but increase in cost due to complexity.

Remember, Jeep is trying to make big inroads in Europe and China. This move is probably linked to that.

Still wished for a 3.5L v6 to replace the 3.9L, ..gm, but thats another thread

 

will the power difference be substantial? i looked for the 2015 grand Cherokee, i didn't notice it being outside of ~5 hp?

on the turbo model, I would assume a fairly large power increase.
