We got the 4.7. Wasn't sold on the cyinder drop & didnt really need the hemi, although I wouldn't mind the hemi a bit. The XK is the wife's & she wanted the 4.7.
As far as mpg, she gets about 14-15 around town/rural and 17 18 mpg hwy/interstate in the Virginia mountains & 17-19....almost 20 (I whish) on the Florida flatlands. I have heard hemi owners say 12-13 around town and not sure about the hwy. I did hear that the cylinder drop occures at something like between 55mph to 65, anything below or above that it doesn't engage. That's not good around the mountains, it wouldn't ever kick in & who drives 55-65
. It would be good for the flater areas though.
We don't have the front and rear elect lockers, that option only came with the hemis in 06. That would have been nice! I think it's an option this year on the 4.7. We like to wheel it and unnecessary wheel spin seems to be gone.
We have an 02 WJ & are familiar with the front end wander or wobble. It's a sfa thing imo. The XK is as responsive as my KJ, just a bit heavier. I was very impressed with the handling and ride.
More pics coming.
