Re: V8 (4.7L) vs V6 Pentastar
I have had pretty much all of them. 2008 SRT8, 04 Overland with 4.7HO, 2012 Overland V6, and now 2014 Summit V8.
Im comparing the 2012 V6 which had that awful transmission which always put it in the wrong gear at the wrong time. Just an all around lame driving experience and I think they may have done that for fuel economy i'm not sure. I haven't driven a V6 with the 8spd, but from what I read its MUCH better.
My 04 Overland with 4.7HO was surprisingly fun to drive. It always had good power and moved out pretty good. Comparing to my 2012 Overland V6 I would say the 4.7HO would pull on it without much problem. Wouldn't be blown away, but it would probably win. I now have a 2014 Summit V8 and wouldn't trade it for ANY of them. LOVE the ZF 8spd and the sound of the engine. It just sounds so good and that tranny shifts awesome! Some may think i'm crazy, but I went with the V8 in my new Summit partially just because how it sounds in the cabin. IMO changes the entire driving impressions and makes it feel like a more significant vehicle. The old 4.7HO also had a great tone to it.
