X2, V8s are fun though offroad one wouldn't help me in the least on the trail types I prefer.My answer is because the vehicles power is just enough -on the road it really 40-50 more horses would be a joy-
at the same time, off road in rocks the 4.0 is actually lethal. I have a V8 TJ, and bear in mind I’m not totally dialed with it and it sure isn’t dialed in either, it can be a handful if you aren’t careful, where the 4.0 is smooth, precise and just keeps going with no drama. Oh the V8 is fun , but the 4.0 is pretty effective ...but certainly doesn’t need any weight hindrance.
