The 3.6 is definitely an improvement over the 3.7 for sure. It's not really a torque motor more horsepower RPM. It's what's in my wife's journey and it will get you in trouble in a hurry. 290 hp and 260 lbs are quite impressive when you think about it. I love my 2005 Grand but wish it had the hemi not the 4.7 but neither get good MPG.
