Wow, it's amazing how varied points of reference are...I test drove both engines and felt a fairly significant difference between the V6 and the Hemi....the Hemi makes the JGC a totally different truck....and that's a good thing.....at least that's the way it felt to me.....oh, and before anyone calls me biased towards the Hemi, I had the Pentastar in the Wrangler and really liked it that application.......funny thing is, the Hemi gets better gas mileage than the my dad's Patriot around town....
